Definitions

  • the invention relates to a single-point valve with the features specified in the preamble of claim 1.
  • the purpose of the invention is to create a single-point fitting which is inexpensive to manufacture and which can be quickly and easily assembled and completed on site.
  • the visible parts of the single-point valve should be replaced quickly and inexpensively during maintenance.
  • EP 0 392 176 shows such an arrangement in which the fitting body which carries the mixing device is designed as a one-piece part with the outlet and is equipped with a multi-part rosette.
  • the valve body has a flange with several through holes, through which it is screwed to a connecting element in a positive manner in the direction of rotation.
  • discharge fittings as modular building block systems, in that a base body is preferably combined with several discharge pieces of different lengths. It is also known that these outlet pieces are rotatably mounted on the connection to the valve body and that these pivot bearings have swivel angle limits.
  • CH 673 689 shows a fitting in which such rotatably mounted covers are present and which can simultaneously serve as a pivotable holder for a flexible spout.
  • the single-point fitting contains, among other things, the operating element 1, the casing 2, the inner body 3, which is preferably formed in one piece, the union nut 4 and a snap ring 5 which is seated in an annular groove 5a of the inner body 3 and is secured by the securing ring 6.
  • the union nut sits with an axial play z approximately corresponding to its length on a shoulder of the inner body 3 and connects the single-point fitting via the snap ring 5 and the locking ring 6 and via seals 25 in a rotationally non-positive manner and tightly to the fitting connecting element 7.
  • This arrangement means that the fastening means 4 , 5, 6 can be removed quickly and easily in the mounting direction of the valve against the valve connecting element 7.
  • the valve connector 7 consists of a housing 26 and an insert 27 rotatably inserted in the housing 26 with two channels 28 for cold and hot water, which are aligned with corresponding channels 29 of the inner body 3.
  • two pins 30 formed on the insert 27 engage in corresponding bores 31 of the inner body 3. It is thereby achieved that the housing 26 can be mounted in the wall in any rotational position.
  • 27 hot and cold water connections can be swapped by turning the insert. The non-positive connection between the inner body 3 and the connecting member 7 therefore facilitates the installation of the supply lines.
  • the rosette 8 carries in its inside means for water-tight sealing against the wall 23 on the one hand and against the casing 2 of the single-point fitting on the other hand, as well as a screw 10.
  • This screw 10 spreads the seal 9a frictionally against the casing 2 when screwed in and thus serves as a fixing element for the rosette on the single-point fitting to keep the sealant under the rosette for years.
  • the type of attachment of the union nut 4 by means of a snap ring 5 and locking ring 6 allows on the one hand a smaller diameter of the fitting body 2 and 3 than that of the union nut and on the other hand the aforementioned quick and easy assembly of the union nut 4 after the rosette, designed as a one-piece assembly with loose screw 10 has been pushed onto the casing 2.
  • the rosette can be pushed as far as possible on the casing 2 in the direction of the operating element 1. This creates the necessary space for the appropriate assembly wrench for the purpose of tool attack in the longitudinal grooves 32 of the union nut 4 in the interior of the wall.
  • the rosette 8 can be pushed approximately up to the operating member 1 onto the valve head when the connection to the valve connecting element 7 is carried out with a suitably designed geometry, which is particularly advantageous.
  • the inner body 3 contains the feed lines 29 for hot and cold water from the valve connection element 7 to the mixing element 11 containing the shut-off and mixing device, which is connected in a rotationally fixed manner by means of a cam 12 to the inner body 3, and the mixed water outlet 13, which leads to the coupling part in FIGS then leads to the outlet 14. He also wears the casing 2, which can be pushed onto the inner body 3 from both sides via an O-ring brake 15.
  • the casing can be slid on both sides has the particular advantage that the inner body is already pre-assembled during factory assembly Valve head (control element 1 and mixing element 11), and with the head sheathing 17a and 17b, but without connecting parts (union nut 4, snap ring 5 and locking ring 6), without sheathing 2, without a rosette and without a coupling part according to FIG. 2, can be checked for function and tightness . This means that any leaks on the inner body are immediately visible.
  • both the casing 2 and the one-piece rosette 8 can be easily removed to the front in order to carry out maintenance.
  • the water does not need to be turned off and / or the single-point fitting has to be dismantled from the connection element 7.
  • the casing 2 is held on the inner body by means of the screw 16 so as to be non-rotatable and non-slip, which in turn is absolutely necessary for the permanent pressing of the sealant 9 under the rosette 8 and to maintain the rotatability of the valve head 1, 17, 17a when the valve is operated .
  • the screw head of the screw 16 already produces this holder due to the height H of its screw head in the partially screwed-in state, which brings about the advantages of the following explanations:
  • Fig. 2 the coupling part to the outlet 14, 14a, 14b is drawn again.
  • the screw 16 also serves to hold and prevent rotation of the pivot bearing element 18.
  • the easy interchangeability and combinability of spouts of different lengths and designs 14, 14a with the same single-point fitting body are known.
  • the coupling and mounting of the swivel spouts is usually done on a pin similar to the pivot bearing element 18 by means of fixing screws 20.
  • the pivot bearing elements are mostly screwed or soldered in the valve body in a torsion-proof manner. In the embodiment of the single-point fitting according to the invention, however, this coupling takes place via the easily removable pivot bearing element 18.
  • This pivot bearing element 18 on the one hand contains a groove 19, which serves to limit the swivel angle of the outlet 14, and projects as a pin into this outlet 14.
  • the swivel spout 14 itself is by means of a fixing screw 20 attached to this pin and thus forms, together with the pivot bearing element 18, a preassembled, testable structural unit, which is suitably sealed in itself and against the inner body 3 with O-rings.
  • the pivot bearing element 18 on the other hand carries a collar 21 which serves as a depth stop and which has bayonet-type recesses 22.
  • the above, pre-assembled outlet assembly of the single-point fitting consisting of a pivot bearing element 18 and swivel outlet 14, can be inserted into the inner body 3 quickly and easily by a suitable rotary movement, following the bayonet-type recesses, with the screw 16 not yet fully screwed in. It is then secured against falling out and against twisting in the inner body 3 by screwing the screw 16 to the depth stop. This achieves the double function of the screw 16 (fixation of the casing 2 on the one hand and non-rotatable mounting of the pivot bearing element 18 on the other).
  • a relatively large air space 24 is created between the casing 2 and the inner body 3. This has the advantage of a lightweight construction of the single-point fitting and the temperature insulation against the casing 3. Even if the inner body heats up as a result of hot water tapping, there is a risk of burns when touching the single-point fitting excluded on the casing 3.
