Description

Mouth water intake.

The present invention concerns a water inlet and especially, according to the preamble of independent claim 1, a casing tube for feeding water from a valve box to one or more water inlets of a water inlet mouth of this class.

The mouths of water intake are already known for a long time and in many different versions. They serve primarily as tap fittings for the extraction of water from a public supply network and, for example, provide fire extinguishers to firefighters. Two different versions are known, namely the mouth of water intake under the floor and the mouth of water intake on the floor. Both are constituted by a wrapping tube or one or two-piece valve housing that can be connected, for example, with its upper end to a supply pipe. At least one detachable lid can close the water inlet on its upper side. The water inlets have on their inner side at least one blocking element that is configured as a valve. To maneuver or to close and open this valve or closure, a maneuverable rotating spindle can be used from the outside which runs as part of an inner fitting almost always in a substantially axial direction in the water inlet. The water inlets frequently have a maneuvering bar that is mounted on the cover or on the casing and moves an axially guided spindle nut on the casing (see, for example, Figure 1 of document CH 675 139 TO 5). A connecting tube can transmit the movement of the spindle to the valve. To prevent frost damage caused by water freezing and dilating, such water inlets usually have a drainage system through which water remaining in the casing can escape after valve closure.

A water outlet on the floor can be configured, for example, as a stand-alone column or as a faucet fitting arranged at least partially on a wall of a building. Each water inlet comprises one or several water outlets that are almost always arranged on the sides of the water inlet. The different water intakes can be equipped with additional blocking elements so that each water intake can be opened and closed individually. However, the blocking of the different sockets can also be carried out by means of tap fittings located outside the water inlet.

The water inlets under the floor are preferably equipped with a nominal breaking point because of their exposed position. In the case of damage to the water intake, for example caused by a vehicle that collides with the column on the ground, the water intake mouth simply turns over - without its envelope deforming or noticeably damaging. This makes it possible, for example, specially shaped fixing screws or flanges by means of which the so-called overlapping (tiltable) tube is joined with the stationary envelope tube disposed mostly under the ground. At the same level the inner lining is formed as separable so that, when the superimposed tube is laid, the spindle extension is removed from the superimposed supplement of said spindle. The spindle bearing is disposed below the nominal breaking point, so that, in the case of an overlapping tube tipped over a water inlet, the main valve remains securely closed and, therefore, water losses are avoided. .

The acquisition of water from the different water intakes or water extraction openings is frequently activated by means of an additional blocking element of the extraction side or of a secondary blocking element. It is thus possible that, when connecting an additional acquisition pipe, an existing water transport does not have to be interrupted. Likewise, regulation or dosing functions cannot be preserved with the main locking element of the input side described at the beginning. Such additional secondary blocking organs may be incorporated in the column on the floor or in the superimposed tube of the water inlet.

Water inlets have previously been used primarily as suppliers of liquids, preferably water, for fire protection purposes or sprinkler installations in agriculture. On the contrary, water inlets are today an integral component of modern public drinking water supplies. Thus, they are now increasingly used for tasks such as the extraction of water by public or private consumers, the establishment of provisional connections for the external supply of the pipeline network, the ventilation and air purge of the pipeline network and the pipeline washing for hygienic reasons. Apart from the requirement imposed on water inlets referring to high operational safety, simple operation, high water capacity and long service life, ease of maintenance and maintenance are also at the center of interest today. optimal corrosion protection. To avoid corrosion damage, the inner surface of the casing tube usually consisting of cast iron is generally coated with plastic, fire-galvanized or enameled.

Other water inlets comprise a vertical tube or several chrome steel casing tubes. On the upper flanged end of the tube a head part is seated in which an annular gasket is partially embedded that requests the flange with a sealing action. For the assembly of the chrome steel tubes, mutually screwed flanges are welded at their ends between which joints are usually placed. Also, the valve box, which has a flange for connection to a component of the mains

channeling, is welded with the lower lower casing tube (see WO 02/04752 A1). When such water inlets must also meet strict hygienic provisions, their production and assembly are then quite expensive.

Likewise, it is known to have leak detectors for permanent monitoring of the water supply network at certain points of this pipeline network, especially in water intake ports (see DE 197 57 581 A1) or other components of the supply network, as, for example, in sections of pipe or shaped parts (see EP 1 052 492 A1).

The purpose of the present invention is to propose an alternative water intake which, thanks to its configuration, eliminates or at least minimizes most of the inconveniences known to the state of the art.

This problem is solved according to a first aspect by means of the characteristics of independent claim 1, in which a casing tube is proposed to feed water from a valve box to one or several water intakes of a water intake mouth with other parts thereof and fasteners. The wrapping tube according to the invention is characterized in that it is configured as a profile with a main wall that can be secured with the other parts of the water intake by means of fasteners attacking in these parts of said intake mouth Water. Preferably, the wrapping tube is configured as a profile comprising a main wall that at least partially surrounds an interior space and spatially insulated holding tubes with respect to this interior space and at least partially surrounded by secondary walls.

According to a second aspect, this problem is solved by proposing a water inlet with said profile of the casing tube. The water inlet according to the invention is further characterized in that it comprises as a top seal a cast iron head part with a sealing surface that is requested with a sealing action by a substantially annular joint adapted to the cross section of the profile of the envelope tube.

Other preferred and inventive features are apparent from the dependent claims.

The profile of the casing tube according to the invention has, among others, the advantage that, despite its high stability and pressure resistance, it can be manufactured simply by means of extrusion. Especially the profiles of aluminum casing or aluminum alloys are very easy to transport and assemble because of their small weight. The construction of the wrapping tube as a profile allows the mounting height of the water inlet to be adapted simply on site to local regulations. If necessary, the profile of the wrapping tube can be shortened or cut off easily at any time, for example by sawing.

The water inlet according to the invention has, among others, the advantage that it is made in modular form as a box of standard constructions. This enables a subsequent incorporation of one or more additional water extraction elements with one or several lateral water extraction openings. The profile of the casing tube can also be shortened here simply and at any time in the measure of the mounting height of these water extraction elements, whereby the original mounting height of the intake port is practically not varied. water despite the additional water extraction elements. An overlapping tube of a water inlet according to the invention has - according to the number of water extraction openings in the casting head part and according to the number of additional water extraction elements - a total weight of approximately 15 to 25 kg, which means a weight reduction of approximately 50-65% compared to a conventional superimposed tube of a water intake mouth made of cast iron. This weight reduction is achieved by means of the extremely light casing tube, which preferably consists of light metal materials or composite materials; Aluminum and aluminum alloys are especially preferred. The casting head parts and the water extraction elements, which preferably consist substantially of light metal materials, such as aluminum or aluminum alloys, contribute to this weight reduction. Cast iron head parts and water extraction elements can also be made of cast iron, especially ductile cast iron; however, such materials are heavier than the preferred light metal materials.

Figure 1 shows a cross section through a casing tube profile according to the invention. This is formed as a profile 4 with a main wall 6 that can be secured with other parts of the water inlet, such as with the head part 15 and with the lower case 37 (see Figures 10 to 19 ) by means of fasteners 36 (see Figure 11) that attack in these parts of the water intake. In a preferred embodiment of the profile of the casing tube four clamp tubes according to a first round embodiment are located on the outside and closed. Therefore, this casing tube for feeding water from a valve box to one or several water outlets 2 of a water inlet port 3 is configured as a profile 4 of casing tube. The profile 4 of the wrapping tube comprises a main wall 6 that at least partially surrounds an interior space 5. In this first embodiment of the profile 4 of the wrapping tube this main wall 6 is circular in cross-sectional configuration and completely surrounds the space inner 5. In addition, the profile 4 of the casing tube according to the invention comprises clamping tubes 8 spatially insulated with respect to this inner space 5 and at least partially surrounded by secondary walls 7. In this first form of

realization of the profile 4 of the casing tube the secondary walls 7 only partially surround the clamping tubes 8, since a part of the walls surrounding these clamping tubes 8 is provided by the main wall 6. The four clamping tubes 8 are arranged here entirely on the outer side of the main wall 6, at the same distance from each other. The inner side 9 of the main wall 6 thus has a cylindrical surface 11 and the clamping tubes are located at the vertices of a square delimited by the cross section.

Since the main wall 6 has to withstand significantly higher pressure loads than those supported by the clamping tubes 8 completely isolated from the part of the water inlet that conducts water, this wall is thicker in construction than that of the secondary wall 7 and withstands a test pressure of, for example, 24 bar, corresponding to the respective national prescriptions, and a normal pressure of 16 bar. In very general terms, thanks to the combination of a casing profile 4 according to the invention with a head portion 15 configured in accordance with national requirements, a water inlet is created that meets the national prescriptions of most countries.

The profile 4 of the casing tube shown in Figure 1 has a central interior space 5 and four round clamping tubes 8 spaced uniformly apart from each other and running parallel to the inner space 5. As an alternative to this embodiment, the clamping tubes 8 may also have a different cross section of the circular shape, for example oval (not shown).

Preferably, the shell profile 4 according to the invention has been manufactured as a single-piece straight extrusion profile and has been formed from a material selected from aluminum, aluminum alloys and composite materials. Other light metal materials, such as magnesium, may be at least part of the aforementioned alloys. Preferred composite materials include glass fiber reinforced polymers that are admitted for conduction of drinking water.

Figure 2 shows a cross-section through a profile 4 of a wrapping tube according to the invention with four clamping tubes which, according to a second round embodiment, are located on the outside and partially open. In this second embodiment of the profile 4 of the casing tube this main wall 6 is also configured as circular in cross section and completely surrounds the inner space 5. In addition, the casing tube profile 4 according to the invention comprises clamping tubes 8 spatially insulated with respect to this interior space 5 and at least partially surrounded by secondary walls 7. Unlike the first embodiment of the profile 4 of the casing tube, the secondary walls 7 only partially surround the clamping tubes 8, and that a part of the secondary walls 7 has been removed. Thus, these four clamping tubes 8 are open on one side.

Figure 3 shows a cross section through a profile 4 of the wrapping tube according to the invention with four clamping tubes which, according to a third round embodiment, are located between half and closed. In this third embodiment of the profile 4 of the casing tube this main wall 6 is configured only partially as circular in cross-section and only partially surrounds the interior space 5. The clamping tubes 8 spatially insulated with respect to the interior space 5 are located on a circular line defined by the main wall 6. The walls surrounding the clamping tubes 8 are configured as secondary walls 7 and are visible as thickening from outside and from within the profile 4 of the casing tube. For this reason (in contrast to the embodiments shown in Figures 1 and 2 and 4 to 6), the profile 4 of the casing tube does not have an exactly cylindrical surface inside or out.

Figure 4 shows a cross section through a profile 4 of a wrapping tube according to the invention with four clamping tubes which, according to a fourth round embodiment, are located inside and closed. In this fourth embodiment of the profile 4 of the casing tube this main wall 6 is configured as circular in cross section and only partially surrounds the interior space 5, since the secondary walls 7 penetrate into this interior space. The spatially insulated holding tubes 8 with respect to the interior space 5 are located at the vertices of a square delimited by the cross section. The walls surrounding the clamping tubes 8 are visible as thickening only from within the profile 4 of the surrounding tube configured on the outside as exactly cylindrical.

Figure 5 shows a cross section through a profile 4 of the wrapping tube according to the invention with three clamping tubes which, according to a fifth round embodiment, are located on the outside and closed. In this fifth embodiment of the profile 4 of the casing tube this main wall 6 is configured as circular in cross section and completely surrounds the interior space 5. The spatially insulated clamping tubes 8 with respect to the interior space 5 are located at the vertices of a triangle delimited by the cross section. This can be, for example, an isosceles triangle (as shown) or an equilateral triangle. A triangle with only one axis of symmetry (as shown) or even without any axis of symmetry (not shown) has, on the one hand, the advantage that the mounting direction of at least all the components of a mouth is uniquely determined of water supply arranged on the ground, so that no confusion of any kind is possible. On the other hand, the flexibility for a subsequent variation and re-assembly of the water inlet is limited, so that an additional water extraction element 31 cannot be oriented at will.

Secondary walls 7 surrounding the clamping tubes 8 are visible as thickening only from outside the profile 4 of the inner tube configured inside as exactly cylindrical.

Figure 6 shows a cross-section through a profile 4 of a wrapping tube according to the invention with six clamping tubes which, according to a sixth round embodiment, are located on the outside and closed. In this sixth embodiment of the profile 4 of the casing tube this main wall 6 is configured as circular in cross section and completely surrounds the interior space 5. The spatially insulated clamping tubes 8 with respect to the interior space 5 are located at the vertices of a hexagon delimited by the cross section. This may be, for example, an equilateral hexagon (not shown) or a non-equilateral hexagon (as shown). The hexagon shown has the advantage that with three fasteners 36 (as in Figure 5), the assembly direction of at least all the components of a water outlet disposed on the floor can be turned 180 °. When the profile 4 of the casing tube has up to eight clamping tubes 8 that are located at the vertices of an equilateral octagon delimited by the cross-section, all the components of a water outlet disposed on the ground can then be arranged with respective orientations rotated in 45º. In this case, a respective arbitrary number of fasteners 36 may be used, said number having to be, of course, within a range of 1 to 8. Preferably, at least two are used, but especially preferably three or four fasteners 36 to hold together the components of a water outlet located on the floor.

According to the embodiments 1 to 6 discussed so far, the main wall 6 of the shell profile 4 according to the invention is configured as a substantially round tube. Particularly in embodiments 1 and 2 and 4 to 6 the profile 4 of the casing tube has a cylindrical surface inside or outside 11. Particularly preferred are embodiments 1, 2, 5 and 6, in which the surface cylindrical 11 is located on the inner side 9 of the main wall 6. This is due to the fact that an annular seal 17 applied inside to the profile 4 of the casing (for example, an annular lip seal or an o-ring) can be hermetically joined this cylindrical surface 11 with the head part 15 and the lower housing 37 of a water outlet (see Figures 10 to 13). When this cylindrical surface 11 is located on the outer side 10 of the main wall 6 (not shown), an annular seal 17 applied externally to the profile 4 of the casing tube would then hermetically join this cylindrical surface 11 with the head part 15 and the lower housing 37 of a water outlet. Preferably, the head part is configured as a casting head part 15, the sealing surface 16 of the casting head part 15 being arranged in a groove 18 in which the seal 17 is at least partially embedded. Thus, the water inlet 3 comprises as a top closure a head part 15 with a sealing surface 16 which is hermetically requested by a substantially annular joint 17 adapted to the cross section of the profile 4 of the casing tube.

Figure 7 shows a cross-section through a profile 4 of a wrapping tube according to the invention with four clamping tubes which, according to a seventh embodiment pumped out, are located outside and closed. In this seventh embodiment of the profile 4 of the casing tube this main wall 6 is configured as approximately octagonal in cross section and completely surrounds the interior space 5. The spatially insulated clamping tubes 8 with respect to the interior space 5 are located at the corners of the profile 4 of the casing tube which enclose an angle of preferably around 96-106 ° and, therefore, are at the vertices of a square delimited by the cross section. The angles of the obtuse vertices located between the clamping tubes 8 in this case amount to approximately 164-174 °. The secondary walls 7 surrounding the clamping tubes 8 are visible as thickening only from outside the profile 4 of the casing tube. Especially preferred are the profiles 4 of the casing tube in which the obtuse vertices do not protrude outwardly from the clamping tubes 8 located at the vertices almost at right angles. This has the advantage that in the majority of cases in which an impact of a moving object (such as a car) occurs, it collides only with the secondary walls never subjected to water pressure. If these secondary walls were slightly damaged by the impact, the safety and functional capacity of a water outlet of this class would still be guaranteed.

Figure 8 shows a cross-section through a profile 4 of a wrapping tube according to the invention with four clamping tubes which, according to an eighth square embodiment, are located on the outside and closed. In this eighth embodiment of the profile 4 of the casing tube this main wall 6 is configured as a square in cross-section and completely surrounds the interior space 5. The clamping tubes 8 spatially insulated with respect to the interior space 5 are thus found in the vertices of a square delimited by the cross section. The secondary walls 7 surrounding the clamping tubes 8 are visible as thickening only from outside the profile 4 of the casing tube. The clamping tubes 8 protrude from the outer surfaces 10 of the profile 4 of the casing tube to an even greater extent than in the embodiment shown in Figure 7. This improves the protection of the main wall 6 against damage.

Figure 9 shows a cross-section through a profile 4 of a wrapping tube according to the invention with four clamping tubes which, according to a ninth embodiment pumped inwards, are located outside and closed. In this ninth embodiment of the profile 4 of the casing tube this main wall 6 is approximately star-shaped in cross section and completely surrounds the interior space

5. The spatially insulated holding tubes 8 with respect to the interior space 5 are located at the vertices of the profile 4 of the casing tube that enclose an angle of preferably around 74-78 ° and, therefore, are at the vertices of a delimited square by the cross section. The angles of the super-aerobic vertices located between the clamping tubes 8 are in this case approximately 192-196 °. The secondary walls 7 surrounding the clamping tubes 8 are visible as thickening only from outside the profile 4 of the casing tube. The clamping tubes 8 protrude here from the outer surfaces 10 of the profile 4 of the casing tube to an even greater extent than in the embodiment shown in Figure 7 or 8. This further improves the protection of the main wall 6 against damage.

According to embodiments 3 and 7 to 9, no annular seal 17 internally or externally applied to the profile 4 of the envelope tube (for example, an annular lip seal or an O-ring) can hermetically join the profile 4 of the envelope tube with the part of head 5 and the lower housing 37 of a water outlet. The profile 4 of the casing tube has at its upper end and at its lower end 13 a cutting surface 1a, 1b which preferably runs at a right angle to the axes 14, 14 'of the profile defined by the respective corresponding ends (see Figures 10 and 11). In embodiments 3 and 7 to 9 discussed here, the joint 17 joins one of these cutting surfaces 1a, 1b. Preferably, the head part is configured as a casting head part 15, the sealing surface 16 of the casting head part 15 being arranged in a groove 18 in which the gasket 17 is at least partially embedded. Thus, the water inlet 3 comprises as a top closure a head part 15 with a sealing surface 16 which is hermetically requested by a substantially annular joint 17 adapted to the cross section of the profile 4 of the casing tube.

Figure 10 shows a vertical cross-section through a casting head part 15 of a water inlet 3 according to a first embodiment, with two lateral water extraction openings 20 that are closed with covers of closure 19. On the central axis of this casting head part 15 also runs the upper axis 14 of the profile 4 of the casing tube that joins down to the casting head part 15. The casting head part 15 presents with this end on its lower side a groove 18 comprising a sealing surface 19 and in which a seal 17 is partially embedded in the form of an O-ring. On this joint 17, the upper end 12 of the profile 4 of the casing tube is connected, whose upper cutting surface 1a abuts a surface of the casting head part 15. The joint 17 has an outer perimeter that is somewhat larger than the inner perimeter of the profile 4 of the casing tube, whereby the gasket is somewhat deformed by this profile plugged 4 of the casing tube and is applied tightly to the sealing surface 16 of the casting head part 15 and to the cylindrical surface 11 of the side interior 9 of the main wall 6 of the profile 4 of the casing tube. In the view two secondary walls 7 are shown that project beyond the outer side 10 of the main wall 6.

An intermediate floor 21 hermetically separates a sensor space 22 from the water intakes 2 of the two water extraction openings 20. In this sensor space 20 a leak detector 23 is preferably arranged which is designed to recognize leaks in the Piping network of the drinking water supply to which the water intake port 3 is connected. The casting head part 15 comprises at its center a guide sleeve 24 for a maneuvering bar 25 intended to maneuver the main valve spindle 26 of the water inlet 3. This guide sleeve 24 is preferably immobilized on the intermediate floor 21 of the casting head part 15. The sensor space 22 in the casting head part 15 can be closed with a lid 27 of said space that can preferably be opened only when at least one closing lid 19 of a water extraction opening 20 is opened. It is thus satisfactorily prevented that unwanted zeros or even vandals can open the cover 27 of the sensor space in a simple way and without special tools. The casting head part 15 is substantially constituted by cast iron, especially ductile cast iron, by aluminum or by an aluminum or light metal alloy. The casting head part 15 defines a certain height increase 28 and the profile 4 of the casing tube has been cut to a length measurement 29 so that at least one water extraction opening 20 is located at an extraction height of given water 30 on the ground (see figures 14 to 19). In these water inlets 3 intended for international use (for example, for Germany), a driving screw 33 typical of the country is seated on the spindle extension 25 which prevents the cover 27 of the sensor space from being opened without special tools.

Figure 11 shows a vertical partial section through the foot portion of the water inlet 3 according to Figure 10, with a lower housing 37 and a connecting flange 34 for seating the overlapping tube located above the ground, with the profile 4 of the casing tube and the casting head part 15, on the ascending tube lying under the floor (not shown) or on the main valve housing (not shown) of the water inlet 3. On the shaft In the middle of this lower housing 37, the lower axis 14 'of the profile 4 of the casing tube, which is attached below to the casting head part 15, also runs. The lower housing 37 has on its upper side a groove 18 comprising a surface of sealed 16 and in which a seal 17 in the form of an O-ring is partially embedded. On this gasket 17 the lower end 13 of the profile 4 of the casing tube is connected, whose lower cutting surface 1b abuts a counter surface of the lower housing 37. The gasket 17 can be constructed, for example, as an O-ring or a lip seal and has an outer perimeter that is somewhat larger than the perimeter

inside the profile 4 of the casing tube, whereby the gasket 17 is somewhat deformed by this plugged profile 4 of the casing tube and is applied tightly to the sealing surface 16 of the lower housing 37 and to the cylindrical surface 11 of the inner side 9 of the main wall 6 of the profile 4 of the casing tube.

Two of the secondary walls 7 projecting beyond the outer side 10 of the main wall 6 are shown in the view. On the right side there is a hint (with dashed line) the fastener 36 visible from the outside that runs in the clamping tube 8 formed by the secondary wall 7. The connecting flange shown here 34 also has anchors 35 in which the clamping elements 36 that attack on the casting head part 15 fit and run at least partially in the clamping tubes 8. These clamping elements 36 stabilize the superimposed tube of the water inlet 3 because, by means of these clamping elements 36, an essential part of this superimposed tube is connected to each other, such as the part of cast iron head 15, the profile 4 of the casing tube and the lower housing 37 under tension of the fasteners 36. These fasteners 36 are preferably configured c As solid rods, threaded rods, tubes or cables. Materials that can be applied to tensile and which preferably do not corrode are considered as materials. Especially preferred are threaded bars or metal cables, especially steel

or steel wire. In enclosed tube profiles 4 with closed clamping tubes (see Figures 1 and 3 to 9) the preferred clamping elements 36 are additionally protected against mechanical actions, weather influences and chemical loads (for example, spilled salt). The visible lower closure of a water inlet port 3 according to the invention is formed by a cover 38 that can be adapted in height to local conditions and that partially penetrates the floor material, tar or other vehicle-coated liners. or by pedestrians. The nominal breaking point between the spindle extension 25 and the main valve spindle 26 of the water inlet 3 is located (as indicated in Figure 11) at the height of the lower housing 37.

Figure 12 shows a vertical cross-section through a cast head part 15 of a water inlet 3 according to a second embodiment, with two lateral water extraction openings 20 that are closed with covers of closure 19. As in the similar foundry head portion 15 shown in Figure 10, the upper shaft 14 of the casing tube profile 4 that is attached below to the foundry head portion 15 also runs here on the shaft central mouth of water intake. This casting head part 15 also comprises at its center (preferably on the intermediate floor 21) a guide sleeve 24 for a maneuvering bar 25 intended to maneuver the main valve spindle 26 of the water intake port

3. The sensor space 22 in the casting head part 15 can be closed with a lid 27 of said space that can preferably be opened only when at least one closing lid 19 of a water extraction opening 20 is opened. Thus, it is satisfactorily prevented that unwanted third parties or even vandals can open the cover 27 of the sensor space in a simple manner and without special tools. The casting head part 15 again substantially consists of cast iron, in particular ductile cast iron, aluminum or an aluminum alloy or light metal. The casting head part 15 defines a certain height increase 28 and the profile 4 of the casing tube has been cut to a length measurement 29 so that at least one water extraction opening 20 is located at an extraction height of given water 30 on the ground (see figures 14 to 19). In this water outlet 3, preferably intended for national use in Switzerland, no operating screw is seated on the spindle extension 25, so that the cover 27 of the sensor space is blocked only by means of the two closing covers 19.

Figure 13 shows a partially cut-out three-dimensional view of a water inlet 3 according to a first embodiment with a head part 15 according to Figure 10, a profile 4 of a casing tube according to Figure 1 and a foot part according to figure 11. All parts are provided with reference symbols corresponding to those of these figures. It is generally fulfilled that the same reference symbols also designate equal elements, even if these are not described in detail in each case.

Figure 14 shows a front elevation of a water inlet 3 with two lateral water inlets 3 and with a head part 15 according to the second embodiment, for example for Switzerland. On the ground the cover 38, the preferably straight shell profile 4 and the casting head part 15 are visible. The casting head part 15 defines a certain height increase 28 and the profile 4 of the wrapping tube has broken off to a length measurement 29 so that at least one water extraction opening 20 or at least one water outlet 2 is located at a certain water extraction height 30 on the ground. The clamping elements 36 are not visible here, since the secondary walls close the clamping tubes completely outwards. Unlike this representation, the profile 4 of the casing tube can also form an arc, whereby the upper and lower axes 14, 14 'of the profile are not located one above the other, but enclose an angle of, for example, 90 ° or 135º. For securing a water inlet 3 with a curved casing tube in this manner, steel wire cables are preferably used. The operation of the main valve is then carried out mainly by means of a spindle extension 25 which is incorporated in the element of a building on which the water inlet sits. Thus, an element of the building can be, for example, a bridge part, a retaining wall and also a house wall.

Figure 15 shows a side elevation of the water inlet 3 according to Figure 14. The cover 38 that closes

optically, the water outlet 3 downwards is held together by means of a screw 39 of the same that is not visible here. According to an alternative embodiment (not shown that differs from the one shown here), the cover 38, the so-called "foundation ring", is constructed in one piece. This foundation ring is detachably plugged into the profile 4 of the casing tube during the installation of the water inlet and, after the non-staggered orientation and securing of the lower housing 37 on the ascending tube, it is pushed down on the lower housing until it stops.

Figure 16 shows a front elevation of a water inlet 3 with a lateral water inlet 2 in the head part 15 according to a third embodiment. The cover 38 that optically closes the water inlet port 3 downwards is held together by means of two bolts 39 thereof which are not visible here.

Figure 17 shows a front elevation of a water inlet 3 with a lateral water inlet 2 in the head part 15 and an additional water extraction element 31 seated in a low position with a lateral water inlet 2 according with a fourth embodiment. This water outlet 3 can thus be planned from the beginning and the profile 4 of the casing can be cut to size accordingly. The additional water extraction element 31 with its lateral water extraction opening or with a lateral water outlet 2 has a mounting height 32, is disposed here at the lower end 13 of the profile 4 of the casing tube and comprises tubes of clamp corresponding to profile 4 of the casing tube. The same fasteners 36 can thus be used to secure the water intake mouth as in the type of Figure 16. However, this water intake can also be reformed on site during a revision incorporating the water supply element. extra water extraction 31 and cutting off the profile 4 of the casing tube according to its mounting height

32. This parting can be done by a plumber on site by simply sawing the necessary piece of profile 4 of the casing. Sheath profiles 4 with a cylindrical surface are also preferred here, since the newly created lower cutting surface 1b is not hermetically requested by the joint 17, but rather - in accordance with the first embodiment of the profile 4 of the sheath tube - the inner side 9 of the main wall 6 is requested in this way. The water inlet 2 of the additional water extraction element 31 could also be oriented forward, to the right or to the rear (not shown).

Figure 18 shows a front elevation of a water inlet 3 with two lateral water inlets 2 in the head part 15 and an additional water inlet element 31 seated high with a front water inlet 2 according with a fifth embodiment. The additional water extraction element 31 has a mounting height 32, is arranged here at the upper end 12 of the shell profile 4 and comprises clamping tubes corresponding to the profile 4 of the shell tube. The same fasteners 36 can also be used here to secure the water intake mouth as in the type of Figure 16 or 17. This water intake can also be reformed on site incorporating the water extraction element additional 31 and cutting the profile 4 of the casing tube to the extent of its mounting height 32. The water inlet 2 of the additional water extraction element 31 could also be oriented backwards (not shown).

Figure 19 shows a front elevation of a water inlet 3 with two lateral water inlets 3 in the head part 15 and an additional water extraction element 31 seated at medium height with a front water inlet 2 according with a sixth embodiment. The additional water extraction element 31 also has a mounting height 32, is disposed here approximately in the center of the shell tube profile 4 and comprises clamping tubes corresponding to the profile 4 of the shell tube. The same fasteners 36 can thus be used again to secure the water intake mouth as in the type of Figure 16, 17 or 18. This water intake can also be reformed on site incorporating the extraction element of additional water 31 and dividing the profile 4 of the casing and cutting it to the measure of its mounting height 32. This parting can also be done by a plumber on site. However, as an alternative (as in all other modifications of the water inlet), the plumber can take with him the necessary pieces of the profile of the casing tube to the place of assembly, which is no problem thanks to Your small weight The water inlet 2 of the additional water extraction element 31 could also be oriented forward, to the right or to the rear (not shown).

Within the framework of the present invention, the elements described and shown in virtually any way desired may be exchanged or combined with each other.
