Definitions
- the invention relates to a sanitary outlet unit, wherein a arranged in a flow path in a housing valve element between an open position and a closed position is switchable, wherein the closed position is disposed in the use position below the open position.
- the invention further relates to a method for actuating a valve, wherein a arranged in a flow path in a housing valve element is transferred from a closed position to an overlying open position.
- Flow rate regulator or flow restrictor can be preselected or varied by an axial change in a relative position of an actuating element and a counter element, with a handle being provided on an outlet end face of the outlet insert, which handle is designed as a pushbutton, and wherein by means of a Drucktastmechanik an adjusting movement on the handle in an axial relative movement of the adjusting element and the counter element can be implemented.
- Such pressure sensing mechanisms are usually bistable, so that usually no automatic return to a preferred starting position.
- the invention has for its object to improve in a sanitary outlet unit in compliance with legal requirements, the performance characteristics.
- the features of claim 1 are provided according to the invention in a sanitary outlet unit.
- the valve element has a contact surface which rests in the open position on the counter surface of the housing and is spaced in the closed position to the counter surface, so that the counter surface in the closed position by water in the flow path is wetted, and in that on the valve element an actuating surface is formed, which in the open position can be acted upon by a prevailing pressure in the flow path, so that the abutment surface is pressed against the counter surface.
- the valve element in the open position, the valve element is durable by the pressure prevailing in the flow path.
- valve element can fall, for example due to its own weight, into the closed position lying below the open position.
- the invention achieves that the valve element can be kept durable in the open position automatically, as long as sufficient water flows in the flow path and thus a sufficient pressure is built up. This facilitates the use, since the user can for example manually transfer the valve element into the open position, but does not have to hold the valve element in this open position. This improves the performance characteristics of the sanitary discharge unit, while at the same time meet legal requirements, according to which the standard setting in normal operation is to be the flow-limited setting.
- the loading surface is formed on a side facing away from the contact surface of the valve element.
- a contact pressure can be brought directly to the counter surface.
- a displacement body is formed, which is arranged in the open position in a lockable by the contact surface and the counter surface receiving space and in the closed position at least partially outside of the receiving space.
- a pressure-controlled retention of the valve element in the open position can be improved.
- a receiving space whose volume can be chosen, for example, only slightly larger than or equal to the volume of the displacement body, can be achieved that an additional resistance to an automatic return to the closed position can be developed.
- the embodiment makes use of the fact that water can flow less easily into a receiving space than air, so that removal of the displacer from the receiving space in a water environment is more difficult than in one Air environment.
- the air environment adjusts itself here, for example, when the water flow is switched off.
- the displacement body is guided in the receiving space. This facilitates a defined transfer of the valve element between the closed position and the open position. It is particularly favorable when the displacement body is displaceably guided. This allows for easy movement and may be conducive to assisting the return movement due to gravity.
- At least one discharge channel is formed, can be discharged via the displaced from the receiving space water. This facilitates a transfer of the valve element in the open position, in which the displacement body has to displace water from the receiving space.
- the at least one discharge channel may be favorable for the ventilation of the receiving space upon return to the closed position, to release the displacement body. It is particularly favorable if the at least one discharge channel opens into the flow path. This simplifies the structural design of the sanitary outlet unit and allows easy removal of the displaced water from the receiving space.
- an accessible from outside the housing actuating element is formed, with which the valve element from the closed position into the open position can be transferred.
- the actuator is rod-shaped to be structurally as simple as possible and / or to use as little space in the sanitary outlet unit.
- the rod-shaped actuator is aligned along the flow path. This has the advantage that the valve element can be operated from below the sanitary outlet unit in the position of use.
- control element is well integrated into the external shape of the sanitary outlet unit and on the other hand, no additional changes, for example, to a tap spout, in which the sanitary outlet unit is to be used, in this way required.
- the transfer movement from the closed position to the open position is immediately apparent to the user, since the actuating element moves rectified to the valve element.
- the actuating element is formed separately from the valve element.
- the advantage here is that the actuating element can be released after transfer of the valve element in the open position of the valve element.
- the weight of the actuator must therefore not be held by the water pressure.
- the holding force for the valve element is also increasable as soon as the actuating element is detached from the valve element.
- the invention makes use of the fact that the released part of the loading surface is pressurized during operation and thus can contribute to the holding force of the valve element in the upper open position.
- the actuating element is preferably independent of the Valve element movably arranged.
- a return to an initial position is independent of the valve element executable.
- the actuating element is guided in the housing.
- the advantage here is that the movement of the actuating element is independent of the movement of the valve element definable. A decoupling of the two movements is thus possible. This simplifies the requirements to be complied with tolerances, so that the actuating element and the valve element are easily adjustable. It is particularly favorable if the actuating element is likewise displaceably guided. Thus, a movement of the valve member directly without mechanical reaction by the actuator effected.
- the loading surface is arranged upstream of a flow obstacle in the open position in the flow path.
- a sufficient water pressure can be developed, which can hold the valve element in the open position.
- the flow obstacle is preferably formed by a valve seat of the valve element or on a valve seat, for example close to the valve seat. Additional flow obstacles are thus dispensable, which simplifies the structural design.
- the contact surface is formed on a circumferential rim, which cooperates in the closed position with a valve seat, for example, the already mentioned valve seat to an at least partial closure.
- a closed position is formed in a simple manner, which according to Art a throttle or may be formed with more complex control functions.
- the use of a peripheral brim has the additional advantage that space is provided in a simple manner for the formation of the mentioned contact surface.
- valve element in the flow path upstream of a flow regulator or Mengenbegrenzer in one embodiment of the invention can be provided that the valve element in the flow path upstream of a flow regulator or Mengenbegrenzer.
- the advantage here is that legal requirements are sustainable even in short-term operating conditions.
- a further advantage is that defined flow and / or pressure ratios can be set behind the flow regulator or flow limiter, which enable a particularly good functioning of the sanitary discharge unit according to the invention.
- the contact surface is formed in the closed position on the valve element on the inflow side.
- the displacement body is made of a metallic material.
- the advantage here is that a higher weight is achievable.
- the entire valve element is made of the metallic material. Multi-components are thus avoidable at this point. As a cheap metallic material, for example Brass exposed.
- the actuating element is made of plastic. This allows a particularly simple production of the actuating element.
- the formation of the actuating element made of plastic is particularly favorable when the actuating element is formed separately from the valve element and arranged detachably from this. In this case, it is necessary that the actuator is provided with a sufficient self-weight, since it is not retained by the valve member.
- a flow restrictor is arranged such that the valve element is at least partially shielded in the open position in the circumferential direction.
- an inflow of the valve element by a turbulent flow of water can be reduced or even completely avoided.
- An unwanted detachment of the valve body from the mating surface, which could be caused by swirls and / or reflected currents, which insert between the contact surface and the mating surface, is thus suppressible.
- the flow diaphragm along an entire circumferential length of the valve element so for example over an angle of 360 °, the valve body, in particular its brim shields.
- the flow restrictor can in this case surround the valve body in an annular manner. It is favorable if the flow diaphragm describes a circular ring. Thus, the possibly non-circular valve body fits into the ring of the flow restrictor, without the need for a rotationally fixed guide of the valve body.
- the flow diaphragm can be arranged stationary, for example, on the housing or a carrier or frame part. The advantage here is that energy and / or impulses of turbulent flow portions easily receivable and / or can be conducted around the valve element around. It is particularly favorable if the flow diaphragm is arranged adjacent to the mating surface. Thus, a joining surface or a gap between the contact surface and the counter surface is effectively shielded.
- the flow restrictor shields the valve element at its brim in order to avoid detachment particularly effectively.
- a height of the flow aperture is tuned to a height of the brim.
- the brim can be completely covered.
- the flow diaphragm is arranged along the flow path behind a baffle surface.
- vortices or flows that are reflected by the baffle and flow in the direction of the valve element, well deflected.
- the flow diaphragm protrudes into a valve chamber receiving the valve element.
- a flow rectifier in the flow path in front of the valve element, a flow rectifier is arranged.
- a flow is evenly aligned.
- a development of vortices, which in particular can cause a detachment of the valve element from the mating surface and thus a dropping of the valve element into its closed position, can thus be reduced or even completely suppressed.
- the flow rectifier is designed in multiple stages. This is better to manufacture by injection molding compared to a one-piece design of a single, correspondingly longer flow straightener. In principle, it seems conceivable to take a thick rectifier, which has only one plate or step with holes.
- boundary conditions of the injection molding technique are to be considered, which in the case of the small bores of, for example, 0.25 mm diameter used here, involve the risk that during cooling the boreholes will close again due to shrinkage.
- a multi-level design can help to avoid this effect.
- the so-called aspect ratio ie the ratio of diameter of the holes to the length of the holes can be improved, so that the described closure of holes due to shrinkage can be avoided.
- the flow rectifier may thus have one stage, two stages, or more than two stages, for example three, four or five or more than five stages.
- the flow straightener has at least one use.
- a flow straightener in an existing outlet unit can be retrofitted and / or it is the flow rectifier easily retrofittable and / or replaceable.
- the insert forms a stage of the flow straightener, in particular one of the already mentioned stages.
- the or each insert may in this case be designed as a plate with holes, the holes can cause a rectification by the above-mentioned aspect ratio. If each step is designed as an insert, the rectifying behavior of the flow rectifier can be easily modified by changing the number of inserts and / or by changing the design of the inserts by replacing them.
- At least one passage nozzle is arranged in the flow path between the flow rectifier and the valve element.
- An edge of the passage nozzle can also form a support for the aforementioned inserts. It is particularly favorable if the flow diaphragm is connected continuously to the passage nozzle. Thus, undesirable vortex formation can be reduced or even avoided. In this case, it is particularly favorable if a flow rectifier, for example the flow rectifier already described, is arranged in front of the passage nozzle.
- Turbulences in the downstream valve chamber are thus largely avoidable.
- the contact surface rests against the counter surface in a contact area and outside of the contact area a distance is formed.
- a flat, low gap or even gap-free concerns the contact surface at the interface can be achieved without the manufacturing technically unavoidable surface unevenness in the vicinity of the investment area its function and in particular the adhesion would interfere in the open position.
- a precise fit of the contact surface on the mating surface can be achieved by the investment area is chosen as small as possible.
- the area in which a gap or gap is formed as large as possible compared to the investment area extent along the contact surface.
- the contact area is limited by one stage. This is a particularly simple means, on the one hand to comply with the desired distance beyond the investment area and on the other hand to create a good transition to the investment area.
- the step may in this case be formed in the contact surface and / or in the counter surface.
- the features of the sibling, directed to a method claim are provided in a method for actuating a valve according to the invention.
- the valve element is acted upon in the open position by a pressure prevailing in the flow path, so that a contact surface of the valve is pressed and held against a counter surface on the housing.
- the valve element automatically remains in the open position, as long as a pressure in the flow path is applied. This facilitates operation since a user is not forced to hold the valve element in the open position.
- the valve element automatically falls after a pressure drop in the flow path in the closed position.
- the valve assumes a state in normal operation, in which the valve element is arranged in the closed position. It is particularly favorable if the valve element falls into the closed position due to its own weight. Additional return springs and the like are therefore dispensable.
- the pressure is generated by a valve element in the open position downstream flow obstacle. The advantage here is that no additional pressure generating means are required. It is particularly favorable if the flow obstacle is generated by a valve seat of the valve element and / or if the flow obstacle in the closed position defines a limitation or regulation of the water flow in the flow path.
- the valve element in the open position water is displaced from a receiving space for a displacement body of the valve element.
- the advantage here is that an additional resistance can be built up against an automatic return of the valve element in the closed position, as long as water is available.
- the displacement can take place via at least one discharge channel, for example the already mentioned discharge channel.
- valve element in the closed position by a pending on the contact surface pressure in the flow path in a Valve seat for example, the already mentioned valve seat is held.
- the advantage here is that a return movement of the valve element in the closed position by a pressure in the flow path can be amplified or supported.
- a sanitary outlet unit according to the invention in particular as described above and / or according to one of the claims directed to a sanitary outlet unit, is used.
- the described advantages of the sanitary outlet unit according to the invention can be used in the inventive method.
- FIG. 1 shows a sanitary outlet unit according to the invention in a cutaway view, wherein the valve element is located in the closed position
- Valve element is transferred with the actuating element in the open position
- Valve element in the open position and the 1 is a view from the side, the situation according to Figure 1 in a view obliquely from below on the outlet structure, another outlet unit according to the invention in a cutaway view, wherein the valve element in the closed position is located, the sanitary outlet unit of Figure 6, wherein the valve element is transferred with the actuating element in the open position, the sanitary outlet unit of Figure 6, wherein the valve element is arranged in the open position and the actuating element of the valve element solved, the sanitary outlet unit of FIG 6 in a longitudinal section, an enlarged detail of FIG. 9, the sanitary outlet unit of Figure 6 in an exploded view, the sanitary outlet unit of Figure 9 to illustrate the position of the detail magnification in Fig. 13 and 13 shows an enlarged detail of FIG. 12 with flow velocity vectors.
- FIGS. 1 to 5 will first be described together in the following, with a subsequent discussion of the different switching states.
- a designated as a whole with 1 outlet unit forms inside a flow path 2 for water flowing through.
- the flow path 2 is formed in a conventional manner in a multi-part housing 3.
- a valve element 4 is arranged, which can be switched between an open position ( Figures 2 and 3) and a closed position ( Figures 1, 4 and 5).
- the closed position is in this case arranged below the open position when the sanitary outlet unit 1 is used in use in the orientation according to FIG.
- the sanitary outlet unit 1 is held by a mouthpiece 5 to a valve not shown in a conventional manner.
- a contact surface 6 is formed on the valve element 4.
- a corresponding mating surface 7 is formed, which cooperates with the contact surface 6 such that the mating surface 7 in the open position of the valve element 4 rests flat against the contact surface 6.
- the contact surface 6 is arranged at a distance from the counter surface 7.
- the mating surface 7 is accessible from the flow path 2 in the closed position and is therefore wetted in the presence of water in the flow path 2.
- an application surface 8 is formed on the valve element 4 .
- the loading surface 8 is oriented downwards, while the contact surface 6 is oriented upwards. In other words, the loading surface 8 is aligned in a direction away from the contact surface 6.
- the loading surface 8 is thus pressurized and presses the valve element 4 against the counter surface 7.
- a displacement body 9 is formed, which fits into a receiving space 10.
- the displacement body 9 is shown here by way of example with a cylindrical shape.
- the displacement body 9 is guided displaceably in the receiving space 10 by its inner contour. In the open position, the displacement body 9 fills the receiving space 10 completely. In the closed position, however, the displacement body 9 is partially disposed outside of the receiving space 10 and projects into this only so far as it is necessary for the mentioned sliding guide. Between the displacement body 9 and an inner wall 11 of the receiving space 10 a plurality of relief channels 12 are formed, via which water, which is displaced from the receiving space 10, can flow back into the flow path 2.
- a rod-shaped actuating element 13 is formed, which is accessible from the outside.
- the actuating element 13 is displaceably guided in an outlet structure 14 and acts on the valve element 4 from below, on the loading surface 8.
- the actuating element 13 is formed separately from the valve element 4, so that a part of the loading surface 8 with the actuating element 13 can be covered and released.
- this part of the loading surface is covered in the figure 2 and released in the figure 3.
- the Beauftschungs character 8 is disposed upstream of the valve seat 15 in the flow path 2.
- the valve seat 15 forms a flow obstruction in the flow path 2, so that a pressure builds up in front of the valve seat 15 which holds the valve element 4 in the open position.
- the contact surface 6 and the loading surface 8 are formed on a peripheral rim 16 of the valve element 4.
- the brim 16 partially closes the valve seat 15 in the closed position in order to achieve an additional constriction.
- flattenings 17 are formed on the brim 16, which in itself describes a round basic shape, which each form passage gaps on the valve seat 15.
- the valve element 4 in the flow path 2 is preceded by a known quantity regulator or flow restrictor 18, by which in the vicinity of the valve element 4 defined ratios are adjustable.
- the contact surface 6 is formed in the closed position on the valve element 4 on the inflow side, so that the valve element 4 is guided by the flow pressure in the closed position and held in the firing position as soon as the contact surface 6 is released from the counter surface 7.
- the displacement body 9 and overall the entire valve element 4 are made of brass.
- the actuating element 13 is made of plastic, as is the housing 3 with the outlet structure 14.
- Figure 1 shows the resting state of the sanitary outlet unit 1.
- the valve element 4 is arranged in the closed position.
- valve element 4 During operation, the flow along the flow path 2 is thus defined by the valve element 4 and in particular the flats 17 in the valve seat 15.
- the valve element 4 By a manual pressure on the actuating element 13 from bottom to top, the valve element 4 is transferred to the open position shown in FIG. In this case, water is displaced from the receiving space 10 by means of the displacement body 9 via the discharge channels 12.
- valve element 4 is pressed with its contact surface 6 against the counter surface 7 on the housing 3. In this open position, the loading surface 8 is acted upon by the pressure built up or prevailing in the flow path 2, so that the valve element 4 is held in the open position.
- valve element 4 also remains in the open position when the actuating element 13 is left to itself and separates from the valve element 4 and falls down. This holding in the open position takes place as long as water flows in the flow path 2 and the necessary pressure is built up.
- valve element 4 falls with the displacement body 9 due to its own weight in the closed position shown in FIG 1 back.
- valve seat 15 In the open position, the valve seat 15 has a maximum free inner cross section, so that the flow rate is increased compared to the closed position. It can also be seen from the figures that the pressure which holds the valve element 4 in the open position is produced by the valve seat 15 and subsequent flow obstacles.
- FIGS. 6 to 13 will be described jointly below, with identical or identical components and functional units being designated functionally and / or structurally with the same reference numerals and not being described separately again in the preceding embodiment.
- the remarks on the preceding figures therefore apply correspondingly to FIGS. 6 to 13.
- FIGS. 6 to 13 at least differs from the preceding exemplary embodiment in that - preceded by a passage nozzle 23 - a flow rectifier 20 is formed.
- This flow straightener 20 is composed of two layers of two stages, the first stage 21 and the second stage 22.
- Each step 21, 22 is formed here as an annular insert 34.
- steps 21, 22 are formed, for example, three or more than three stages and / or circular disk-shaped inserts 34.
- a flow diaphragm 19 is formed in the valve chamber 28, which is formed along the flow path 2 behind the passage nozzle 23.
- the flow aperture 19 protrudes into the valve chamber 28 and encloses the valve element 4 along the full circumference of the rim 16.
- the flow aperture 19 is brought close to the counter surface 7.
- the flow aperture 19 has a height that is tuned to a thickness of the rim 16. Thus, the brim 16 is stretched completely behind the flow aperture 19.
- the brim 16 has a non-circular shape with the already described flattenings 17.
- Flow restrictor 19 in contrast, has a shape of a circular ring, which surrounds the rim 16 on all sides. Thus, it is avoided that the brim 16 can collide by rotation about its longitudinal axis with the flow restrictor 19, wherein at the same time the flow restrictor 19 is moved as close as possible to the brim 16.
- the counter surface 7 is divided by a step 26. In this way, a contact region 24 is defined, in which the contact surface 6 and the mating surface 7 lie flat against one another.
- This investment area 24 is only a fraction of the area covered by the valve element 4 and more precisely its rim 16. This small proportion can be produced sufficiently flat in terms of production, so that the abutment surface 6 rests sufficiently close to the counter surface 7 to allow the valve element 4 to pass through Keep water pressure in the upper position.
- FIG. 13 shows the course of the flow in the flow path 2 on the basis of flow velocity vectors 27.
- the drawn line of the flow path 2 is to be understood as an approximate sketch of the basic course of the flow.
- the rectifying action of the flow straightener 20 can be seen from the fact that the flow velocity vectors 27 after exiting the passage nozzle 23 define a general flow direction with a small degree of turbulence. Although subsequent structures cause a renewed increase in turbulence, but to a tolerable level.
- FIG. 11 shows the outlet unit 1 in an exploded view.
- the outlet unit 1 accordingly has a flow regulator 18, on which a front screen (not visible in FIG. 11) is placed.
- the flow regulator 18 has in a conventional manner a control body 35 which defines a control gap 36 with a control profile 36 such that a constant flow rate can be achieved independently of pressure.
- the housing 3 is arranged, in which the perforated plate-like inserts 34 are inserted, which form the steps 21, 22 of the flow rectifier 20.
- the receiving space 10 is formed, which receives the displacement body 9 of the valve element 4.
- the baffle 32 follows the housing 3 and provides the baffle 29 (see Fig. 10) and the valve seat 15.
- the actuating element 13 is connected to the outside with a sleeve-shaped handle 33.
- the actuating element 13 can thus be actuated from the outside, without having to intervene in the water jet.
- This connection is realized in the present embodiment via the outlet structure 14. But it can also be formed separately from the outlet structure 14.
- a sleeve part 38 receives the Zerlegerteil 31, the baffle 32 and the housing 3 with doseclipstem flow regulator 28.
- the sleeve part 38 is held in the outlet nozzle 5, which in a fitting outlet (not shown) can be screwed.
- a contact surface 6 is formed on a valve element 4 which is adjustable in a flow path 2 between an open position and a closed position, which in the open position covers a corresponding, stationary counter-surface 7 and releases it in the closed position, so that the valve element 4 is automatically held in the open position by the pressure in the flow path and returns to the closed position upon pressure drop.
