Definitions

the invention relates to a drain fitting with odor trap, with a housing having a drain, which forms a housing chamber, and with an extending into the housing chamber dip tube, which is spaced from the housing base and the housing limits a reservoir volume, wherein of the reservoir volume a nozzle for the connection to a line system emanating, wherein in the housing a the reservoir volume is connected to the interior of the nozzle connecting piece connecting portion is provided, and wherein the odor trap is effected by means in the dip tube and in the reservoir volume Sperrwasser held.
Drain fittings with odor trap are already known in the art.
the patent application EP 0 634 530 A1 discloses an odor trap which has a ball floatable in the sealing water. If the level of the sealing water falls below a level ensuring the odor trap, for example because a large part of the sealing water has been sucked out by a negative pressure in the line system connected to the drain fitting, the ball settles in a ball seat arranged on the immersion tube and thus mechanically prevents the ingress of gases from the tank Sewer system in the drainage room.
the object of the present invention is to provide a drain fitting with odor trap, which at least largely avoids the aforementioned disadvantages and, in particular, requires a small installation space.
a drain fitting with odor trap of the type mentioned in that a construction element is provided which is designed such that it causes a change in the flow behavior in a leading from the interior of the dip tube to the nozzle connection portion flow channel, in particular changes the flow cross-section of the flow channel , preferably extended.
part of the sealing water remains in the reservoir volume and can ensure the odor trap. If the level of the sealing water has reached approximately the height of the end face of the immersion tube facing the housing base due to the pressure conditions, there is a risk that the sealing water will be drawn off to such an extent by the passage of air through the immersion tube and the reservoir volume into the connection or the conduit system the odor trap after the end of the pressure disturbance can not be reliably restored.
the drain fitting With the configuration of the drain fitting according to the present invention, it becomes possible to hold the amount of sealing water necessary for the odor trap in the reservoir volume even when air is sucked into the piping system through the drain, the dip tube and the reservoir volume. Because of the construction element, the flow cross section of the leading from the interior of the dip tube to the nozzle connection portion flow channel - that is essentially in the reservoir volume - modified so that an air channel is formed in the flow channel located in the sealing water through which sucked through the flow of air into the pipe system can get. By this type of "short circuit" is largely avoided that too much sealing water is lost in pressure disturbances in the pipe system.
the provision of the sealing water in the reservoir volume ensures the restoration of the odor trap by means of sealing water even with repeated pressure disturbances.
the appropriately designed drain fitting is thus particularly suitable for connection to piping systems in which pressure fluctuations occur more frequently.
the construction element is formed by a partial, radially outward recess in the nozzle connection section.
the partial recess thus preferably extends only over a certain portion of the circumference of the housing.
the partial depression causes in particular a cross-sectional widening of the flow channel and thus a pressure reduction in the water, which flows through the flow channel at a pressure prevailing in the line system negative pressure.
the pressure reduction leads in particular to the fact that - as soon as air is sucked in - a stable air duct from the interface between air and water, for example in the Immersion tube, formed to the nozzle connection section.
the flow of air, which is sucked in the case of the sinking of the sealing water level to about the height of the lower end side of the dip tube from the drainage chamber through the dip tube and the reservoir volume in the conduit system can be directed by means of a simple structural design in an air duct.
the reservoir volume can advantageously hold a quantity of sealing water necessary for the restoration of the odor trap.
the partial recess in the nozzle connection portion is formed so that it is directly upstream of the nozzle in the flow direction.
a retaining barrier retaining the sealing water in the reservoir volume is arranged, and the vertical distance between the housing base and the nozzle barrier is preferably between 30 mm and 50 mm. In this way, a particularly flat and therefore easy to install design of the drain fitting can be ensured.
the partial depression may extend approximately to the height of the nozzle barrier. In this way, the formation of the air duct in the case of a negative pressure can be influenced up to the level of the maximum possible in the reservoir volume Sperrwasserpegels.
the reservoir volume approximately at the level of the nozzle barrier and / or the recess has a radial foreign extended section on.
the extended section for receiving in particular from the dip tube Withschogenem barrier water, and thus as a kind of additional barrier water receiving volume, act.
an increased amount of sealing water can be kept available, which helps to restore after the decay of the pressure disturbance a reliable function of the odor trap ensuring sealing water level in the reservoir volume and in the dip tube.
the nozzle connection portion preferably connects the extended portion to the interior of the nozzle.
the barrier water stored in the above-mentioned additional barrier water receiving volume can thus flow back into the lower part of the reservoir volume or into the dip tube by the action of gravity.
the construction element is preferably designed such that a complete suction of the sealing water from the reservoir volume caused by pressure fluctuations in a line system connected to the drain fitting is prevented.
the design of the construction element for example the depth and / or the shape of a partial recess at the nozzle connection section, is preferably in coordination with individual specific parameters or any combination of these specific parameters of the drain fitting, for example, the volumes of the dip tube and the reservoir volume, the intervals between sequence and housing base or housing base and nozzle barrier, as well if appropriate, taking into account the pressure fluctuations typically occurring in piping systems.
the dip tube widens inwards and / or outwards towards the housing base and in particular has a concave curvature.
the flow conditions of draining water in the dip tube and in the surrounding reservoir volume, and thus in the flow channel can be optimized.
a mandrel in the dip tube preferably only in the expanded portion of the dip tube, that is not beyond, extend.
a formation of depressions on the housing base which can affect the flow conditions, be prevented.
the risk of deposits in the storage space of running water in the middle of the housing base is reduced.
the flow cross-section between the end face of the immersion tube facing the housing base and the housing base and / or between the end face of the immersion tube facing the housing base and the housing wall radially outwardly limiting the reservoir volume is the smallest and increases immediately thereafter.
the flow cross section smaller than at any other point of the flow channel.
the flow cross-section is greatest in the region of the partial depression. The largest flow cross-section can be widened by more than 10%, in particular by more than 20%, compared with the smallest flow cross-section. In this way, particularly favorable flow conditions of the water in the flow channel are effected.
such an embodiment has an advantageous effect on the formation of an air channel for "short-circuiting" the drainage space with the line system in the case of a pressure difference, which not only stops for a short time.
the reservoir volume can be designed, for example, as an annular space, in particular a torus. But there are also other fulfilling the same function, geometric shapes of the reservoir volume possible.
Fig. 1 shows an embodiment of the drain fitting 2 with odor trap according to the present invention.
a circular in this example 6 is incorporated.
a edge-supported screen or a edge-supported filter (not shown) can be placed in order to prevent the penetration of solids into the housing chamber 4a.
a dip tube 8 is fixed to the housing 4, which extends into the housing chamber 4a until shortly before the housing base 10 and is thus spaced therefrom.
the dip tube 8 has a concave curvature in this example, whereby the flow behavior of a running through the drain fitting 2 fluid, such as water, favorably influenced and the volume of the dip tube 8 can be reduced.
an approximately conical mandrel 12 is arranged, which extends over the plane of the lower end face of the dip tube 8 in the direction of the drain 6 in the dip tube 8.
the mandrel 12 advantageously prevents the formation of depressions on the housing base 10, which adversely affect the flow behavior and in which deposits can settle.
annular space 14 has at one point StutzenanInstitutabêt 16 a and a nozzle 16 for connecting the drain fitting 2 to a line system (not shown), for example, a service water or greywater pipe system on.
a line system for example, a service water or greywater pipe system on.
the annular space 14 has a radially outwardly widened section 21 arranged just below the nozzle barrier 18 in order to create an additional volume in the annular space 14 for receiving sealing water (not shown).
the nozzle connection portion 16a is slightly below the barrier height in this example partial, radially outward recess 20, which acts as a structural element.
the partial depression 20 modifies the flow cross-section of the flow channel leading from the interior of the dip tube 8 to the nozzle connection section 16a. Due to the partial depression 20, it is possible, in the case of a negative pressure in the connected line system, to channel the flow of the air sucked in at the drain 6 so that a large part of the sealing water (not shown) is not sucked away in the annular space 14. Rather, a portion of the sealing water can be kept in the annular space 14 during the pressure disturbance. After the release of the pressure disturbance, the so-held barrier water can flow back into the dip tube 8 and restore the required for the odor trap sealing water level.
Fig. 2a shows in a schematic cross-sectional view of the drain fitting 2 from Fig. 1 ,
the immersion tube 8 and the annular space 14, as far as possible are filled with sealing water (hatched area) up to the maximum height 22 of the nozzle barrier 18 at the nozzle connection section 16a.
sealing water hatchched area
In the in Fig. 2a shown normal state prevail both in the discharge space above the drain 6 and in the pipe system to which the drain fitting 2 is connected via the nozzle 16, equal pressures p 1 and p 2 .
the sealing water thus reliably prevents the ingress of gases from the conduit system into the drainage space.
Fig. 2c It is shown how a complete suction of the sealing water from the annular space 14 is prevented via the nozzle barrier 18 in the conduit system according to the present invention. Due to the partial recess 20 in the nozzle connection portion 16a on the annular space 14, the flow behavior of the sucked from the drain 6 air (dashed arrows 30) is channeled so that only a small portion of the reproached in the annular space 14 sealing water is lost. The sucked air is supplied to the conduit system via the nozzle 16 to form an air channel 32 in the sealing water.
the flow conditions shown here are to be understood as schematic or by way of example and, depending on the design of the construction element which modifies the flow cross section of the flow channel leading from the interior of the dip tube 8 to the nozzle connection section 16a, assume a different shape. As long as the pressure difference p 2 > p 1 persists, despite the air channel 32, the odor trap of the drain fitting 2 is ensured, because the flow direction of the air prevents gases from entering the drainage system through the drain fitting 2 in the drainage chamber.
Fig. 2d finally shows the state of the drain fitting 2 after the balance of the pressures p 2 and p 1 .
the in the annular space 14 - in particular advantageously in the radially outwardly widened portion 21 as an additional barrier water receiving volume - held captive water can now flow back into the dip tube 8 (solid arrow 34) until the sealing water level in the dip tube 8 and in the Annulus 14 are approximately at the same height 36.
the volumes of the dip tube 8 - by the formation of a concave curvature - and the annulus 14 - taking into account the partial recess 20 and the radially outwardly widened portion 21 - are adapted in this example to each other so that the sealing water level in the annulus 14 of the level 22 of the nozzle barrier 18 drops to the next lower level shown 36.
the next lower level 36 from the housing base 10 in the vertical direction 38 by about 30 mm, in particular 32 mm, spaced. In this way, a drain fitting 2 can be implemented with reliable odor trap even with low height.
