Definitions

  • the present invention relates to a valve device for mounting on a fluid-carrying line, in particular a faucet, with an inlet nozzle, on which a valve body is provided for opening and closing a passage to a distribution chamber, wherein provided at a bottom of the distribution chamber outlet openings for generating an outgoing jet are, and a hanging on the floor operating lever which opens or closes the valve body by pivoting.
  • valve device With which a fluid flow from a faucet can be opened or closed.
  • a valve body is provided, which is movable by pivoting an actuating rod, wherein the actuating rod rests with a head portion on the underside of the valve body.
  • the exiting water jet is irregularly strong and injected in different directions, because the head portion of the actuating rod is at a pivoting of the actuating rod obliquely in the distribution chamber, so that different pressure conditions result by deflecting the water jet.
  • the result is a splashing jet of water.
  • the user can forget to turn the tap after use, since the valve body completely closes the water outlet. This can lead to problems if the user moves away from the faucet and only after a leak occurs, which is then no longer noticed.
  • a jet distributor plate is arranged between a head of the actuating lever and the valve body, so that a misalignment of the head by pivoting the actuating lever has no effect has on the exiting beam.
  • the jet distributor plate preferably has an area of at least 20 mm 2 , in particular at least 100 mm 2 , on the side facing the valve body. As a result, a planar deflection of the incoming fluid flow is achieved, which is distributed in a ring around the jet distributor plate.
  • the jet distributor plate is guided linearly in the distribution chamber.
  • the beam distribution plate upon pivoting of the actuating lever, the head of the actuating lever, the beam distribution plate move away from the ground to lift the valve body.
  • the beam distribution plate may be fixed, for example on the housing. Then, the beam distribution plate may have an opening which is penetrated by the valve body or another actuating element.
  • this can have an annular step or a guide bar which cooperates with a web projecting from the base and only permits a linear movement of the jet distributor plate.
  • valve body may be fixed to the jet distribution plate or formed integrally with the jet distribution plate.
  • a wall section is arranged in the distribution chamber on an inlet side, which surrounds the jet distribution plate in a raised position with an open valve body.
  • a substantially uniformly wide gap can be formed between the wall section and the jet distributor plate, preferably an annular gap which forms a flow resistance and equalizes the flow velocity.
  • at least one ventilation opening is provided adjacent to the wall section on the side facing away from the jet distributor plate, from which ambient air can be sucked.
  • at several points adjacent to the bottom of a ventilation duct to the ventilation opening be formed, preferably an annular ventilation channel.
  • an annular air gap between the actuating lever and the floor may also serve as a ventilation opening.
  • a strainer may further be arranged on the inlet port.
  • a valve device is further provided in which at least one bypass opening is formed towards the distribution chamber, that is to say an opening which forms a flow channel into the distribution chamber parallel to the passage with the valve body.
  • the bypass opening has a maximum cross section of less than 3mm 2 , preferably about 0.3mm 2 .
  • the bypass opening may have a maximum opening diameter of less than 2 mm, in particular less than 0.7 mm.
  • the bypass opening may be circular or formed with another shape, so that only a small volume flow passes into the distribution chamber.
  • a sieve is arranged in front of the bypass opening whose mesh size is smaller than the diameter or the opening width of the bypass opening. This prevents the bypass opening from becoming dirty and thus losing its functionality.
  • the bypass opening is formed in the Ventilgroroper, so that a sieve can be arranged on the inlet nozzle to the valve body.
  • a valve device 1 comprises an upper housing part 2, on which an inlet pipe 3 is formed.
  • a valve body 4 is arranged, which can be applied with a contact surface on a sealing ring 30 in order to close the inlet pipe 3.
  • a sieve 5 is arranged, by means of which an entry of dirt particles to the valve body 4 is prevented.
  • a fluid can flow through the inlet port 3 to a distribution chamber 6, which between a lower housing part 8 and the upper housing part 2 is formed.
  • a jet distributor plate 7 is arranged, which forms a circular planar surface and distributes an incoming fluid in an annular manner.
  • the lower housing part 8 has at a bottom 80 a plurality of outlet openings 81, through which an outgoing jet can be passed.
  • a directed to the upper housing part 2 web 9 is formed, on which the beam distributor plate 7 is guided linearly.
  • the jet distribution plate 7 is movable via an operating lever 10 having a thickened head 11 which is held on the bottom 80.
  • at least one web 12 is formed adjacent to the head 11 on the actuating lever 10, which protrudes radially from the actuating lever 10.
  • a thickened handle portion 13 is formed on the operating lever 10 in the lower region.
  • valve device 1 In the FIGS. 1 and 2 the valve device 1 is shown in the closed position.
  • the valve device 1 can be fixed via a sleeve 14 with an internal thread at an end portion 16 of a faucet 15, as shown in FIG FIG. 2 is shown. Then, a fluid in the faucet 15 can be prevented from flowing out, for example, to save water during brushing, shaving or hand soaping.
  • the operating lever is pivoted, as shown in the FIGS. 3A and 3B is shown.
  • the head 11 is inclined and presses the jet distributor plate 7 upwards in the direction of the inlet nozzle 3.
  • the valve body 4 is raised so that an annular gap is formed between the valve body 4 and a sealing surface 30, for example an O-ring.
  • a water jet corresponding to the dashed line 26 can flow from the water line 15 through the inlet connection 3 and the distribution chamber 6 to the bottom 80 and generate a jet 17 there through the outlet openings 81.
  • annular ridge 20 on the housing upper part 2, which surrounds the beam distribution plate 7.
  • annular gap 21 is formed, which has a substantially constant width distributed over the circumference and thus ensures an annular distribution of the fluid.
  • a plurality of ventilation openings 22 are provided distributed over the circumference, can be sucked through the air, as indicated by the dashed line 25 (FIG. FIG. 3B ) is shown.
  • a annular gap 28 is formed to the adjacent sleeve 14, so that air adjacent to the bottom 80 to the vent opening 22 in a ventilation channel 28 can flow.
  • the lower housing part 8 is connected via a wall portion 23 with the sleeve 14.
  • the web 20 covers in the radial direction the ventilation opening 22, so that air is sucked through the ventilation opening 22, and the beam is formed simultaneously.
  • the jet distributor plate 7 presses against the head 11 of the operating lever 10 and pushes it into a vertical position. As a result, the jet distributor plate 7 can be displaced downwards, so that the valve body 4 rests again on the sealing surface, such as the sealing ring 30. In this position, the faucet 15 is almost completely sealed by the valve device 1, wherein in the valve body 4, a bypass opening is recessed, having a diameter of less than 2 mm, preferably less than 0.7 mm.
  • a second valve such as a shut-off valve for the faucet 15. This avoids Leakage occurs at a later time when the user has gone away and the valve device 1 is damaged.
  • FIGS. 4A to 4D the upper housing part 2 of the valve device 1 is shown.
  • the inlet stub 3 there is a passage opening 31 to the distribution chamber 6, wherein three inwardly projecting webs 32 are arranged on the passage opening 31.
  • the webs 32 form a guide so that a cylindrical portion of the valve body 4 is guided linearly and is prevented from pivoting.
  • the annular web 20 Integral with the upper housing part 2, the annular web 20 is formed, in which the beam distribution plate 7 can be at least partially inserted.
  • the valve body 4 comprises a head portion 40, in which a bypass opening 41 is arranged.
  • the bypass opening 41 has a larger diameter inlet section 42 and a smaller diameter channel 43.
  • the bypass opening 41 has at its narrowest point a cross-sectional area of less than 7 mm 2 , preferably less than 0.28 mm 2 .
  • a conical contact surface is formed, which can be applied to the sealing ring 30.
  • the head portion 40 is followed by a cylindrical portion 45 which is guided substantially linearly on the webs 32 of the upper housing part 2.
  • the valve body 4 further includes a plug-in element 46, which can be inserted into a corresponding receptacle on the jet distributor plate 7 and clamped there. It is also possible to form the valve body 4 integrally with the jet distribution plate 7.
  • a substantially cylindrical side surface 71 is formed, which is insertable into the web 9 and is linearly guided there. Further, at one end of the side surface 71, a groove 70 is formed, which has an outer side wall 72 and into which the web 9 can be inserted. This ensures that the jet distributor plate 7 can only be lowered and axially guided to the head 11 of the actuating lever 10 by a predetermined amount.
  • the screen 5 is shown mounted on the inlet port 3.
  • the screen 5 comprises a plate 50 on which a plurality of entry slots 51 are formed.
  • the screen 5 can be inserted with a projection 52 into the inlet port 3, wherein the inlet slots 51 have a width which is smaller than a maximum opening width of the bypass opening 41. This prevents dirt particles from passing through the screen 5, which pollute the bypass opening 41 could.
  • the slots 51 may therefore have a maximum width of 0.5 mm, that is smaller than the bypass opening 41, with a larger chosen bypass opening, the slots 51 should always be smaller than the bypass opening 41, in order to avoid clogging of the bypass opening. It is also possible, instead of the inlet slots 51, to provide a plurality of inlet openings which have a geometry other than the slot shape, for example circular, having a maximum opening width of less than 0.5 mm.
  • FIGS. 7A to 7D the housing lower part 8 of the valve device 1 is shown.
  • the lower housing part 8 is substantially cup-shaped with a bottom 80 formed on the ring a plurality of outlet openings 81 are formed. Between the outlet openings 81 individual webs 84 are arranged. In a central region of the bottom 80, an opening 82 is arranged, through which the actuating lever 10 is inserted. Further, at the opening 82 radially opposite recesses 83 are formed, which are dimensioned so that the actuating lever 10 with the webs 12 through the Recesses 83 can be raised.
  • the head 11 can be moved upward via the grip section 13, wherein the webs 12 are then rotated by an angle via the grip section 13, so that the beam distributor plate 7 can be fixed in a raised position, so that the valve body 4 remains open.
  • the user can also permanently open the valve device 1, wherein the outgoing jet 17 has a lower volume flow than without valve device 1, since a large number of flow resistances are to be overcome on the valve device 1.
  • the annular web 9 is formed, which holds the jet distributor plate 7 from below and causes a linear guide 7.
  • an inner housing wall 24 is formed, which forms a boundary for the outer ventilation channel 28.
  • an outer housing wall is provided in regular sections, on which the sleeve 14 rests.
  • An upper wall section 23 can be fixed to the sleeve 14.
  • FIG. 8 a modified embodiment of a valve device is shown, in which a jet distributor plate 7 'is arranged stationary and fixed to the lower housing part 2 or is formed integrally therewith.
  • a jet distributor plate 7 ' In the jet distribution plate 7 ', an opening is provided through which a cylindrical portion 45' of a valve body 4 'is performed.
  • the head 11 presses against an underside of the portion 45 'and thereby pushes the valve body 4' upwardly to open the valve device. Then, the fluid flows through the distribution chamber 6 to the bottom 8, as in the previous embodiment.
  • the stationary arrangement of the jet distributor plate 7 ' has the advantage that very uniform flow conditions are present on and in the valve device.
  • the beam distribution plates 7 and 7 ' have a flat surface. It is of course also possible to form the jet distributor plate slightly conical in order to make an annular distribution of the fluid. In addition, the jet distribution plate 7 may also be annular and have a central opening. Other geometries for the annular distribution of the fluid jet should be understood as a "beam distribution plate" in the context of the application.
  • valve body 4 is formed closed and has no bypass opening 41. Then the valve device 1 also cause a complete closing of a fluid-carrying line 15.
  • bypass opening 41 in the valve body 4, but in the upper housing part 2. Then, the bypass opening ensures a slight drop in the valve device, even if it is closed.
  • ventilation openings 22 are provided laterally on the lower housing part 8.
  • the ventilation can also take place at a different location of the lower housing part 8, for example via the floor 80.
  • the head 11 of the actuating lever 10 is preferably arranged in a chamber which is arranged separately from the water-conducting region of the distribution chamber 6. It is also possible that the chamber communicates with the distribution chamber 6 through smaller openings, as long as the flow is not significantly affected thereby.
