Definitions

  • the invention relates to a drain valve for a liquid container, in particular for a toilet cistern, with an outlet opening, the drain valve returning to its closed position after the opening process and at least partial emptying of the liquid.
  • the drain valve In known water cisterns for sanitary facilities, the drain valve is arranged in the bottom of the cistern. In the shut-off position, a drain opening in the bottom of the water cistern is shut off by a sealing ring disk made of an elastomer, which is supported by an annular flange on an overflow pipe. During the opening process, the overflow pipe is lifted by the user and thus the drain opening is released, the overflow pipe with the sealing ring disc being held in the open position by a float during the flushing process. After the rinsing process has been completed, the overflow pipe with the sealing ring disc falls back into the shut-off position.
  • the invention has for its object in the preamble of the drain valve specified in such a way that with simple means a safe barrier is achievable.
  • this object is achieved by that the outlet opening of the drain valve at a in its height protruding into the liquid container movable tube is formed, being in the closed position the outlet opening of the pipe from one Float held above the liquid level and that a device is provided with which the float is retractable.
  • the tube having the outlet opening can expediently be connected to a bellows or a rolling membrane in the region of the connection for the flushing line, the float advantageously comprising a foam ring which is fastened to the tube in the region of the outlet opening, or else as a hollow body with an air chamber and a flood chamber, which is formed directly on the tube in the region of the outlet opening.
  • a linkage with which the float can be submerged or sunk with the outlet opening of the tube can expediently be provided as the actuating device.
  • the actuating device can be designed such that a different amount of liquid can optionally be dispensed, one or more limiting arms then being able to be provided on the linkage of the actuating device, of which the float is optionally held at an adjustable height during the sinking process, so that the liquid container is then only partially emptied.
  • the drain valve according to the invention is particularly suitable for sanitary water flushing devices suitable. But it can also beneficial in liquid containers for others Purposes, e.g. for a surge emptying.
  • a first exemplary embodiment is shown schematically, a liquid container 2 being shown only in part.
  • the liquid container 2 has a base 22 and a cover 21, a connection 23 for a flushing line being formed in the base region.
  • the liquid container 2 is filled with water from a float-controlled filling valve (not shown in the drawing) up to the maximum liquid level 20, as shown in FIG. 1.
  • a roller membrane 12 with a sealing ring 121 is pressed into a depression 220 coaxially with the connection 23.
  • the other end region of the rolling membrane 12 is guided with a sealing bead 120 over the outer jacket of a tube 10, a sealing bead 120 being accommodated in a circumferential annular groove on the tube 10.
  • the tube 10 is expanded in a funnel shape above the sealing bead 120 and carries in this area a float 3 designed as a foam ring, which also rests with its inner wall on the sealing bead 120 of the rolling membrane 12.
  • An outlet opening 1 is provided in the tube 10 above the float 3.
  • the float 3 carries the pipe 10 connected to the connection 23 via the rolling membrane 12 with its outlet opening 1 above the liquid level 20, so that no liquid is dispensed via the connection 23 in this position. The drain valve is thus in the closed position.
  • a throttle funnel 5 is arranged coaxially in the tube 10, the throttle funnel 5 being held at a distance from the inner wall of the tube 10 by means of ribs 50.
  • a linkage 4 of an actuating device is arranged coaxially to the tube 10 and the throttle funnel 5.
  • the linkage 4 passes through an end region 41 through the narrowest region of the throttle funnel 5 and thereby additionally reduces the passage cross-section, so that during the opening process the outlet opening is pressed more towards the bottom 22 of the liquid container 2.
  • an annular wall 30 is formed, on the front side 300 of which two diametrically opposite transverse arms 40 of the linkage 4 rest when the liquid level 20 has the level shown in FIG. 1.
  • the linkage 4 is in this case received at an end region in an axially displaceably guided manner by a pot-like bushing 45 which is locked in a bore in the cover 21 with the aid of snap tongues 450.
  • a compression spring 43 is arranged coaxially in the bushing 45 and, on the other hand, is supported on a pusher 44 which is arranged to be axially displaceable to a limited extent in the bushing 45 and is connected to the linkage 4.
  • the throttle funnel 5 is also emptied, so that the float 3 with the outlet opening 1 formed on the tube 10 again comes above the water level 20 due to its buoyancy and thus brings the drain valve into the shut-off position.
  • the liquid level 20 can be refilled to the level shown in FIG. 1 via the filling valve (not shown in the drawing).
  • the flushing process can then be initiated again with the push button 44.
  • the pipe 10 is guided by the linkage 4 during the floating process and during the lowering process.
  • a bellows 11 is connected in a rotationally fixed manner to a pipe 10 carrying an outlet opening 1 and, on the other hand, is held in a rotationally fixed manner with a pipe pin 111 in the inner region of a connection 23 for a flushing line, an O-ring 112 being arranged in the region of a depression 220 for sealing purposes.
  • the bellows 11 each have a wire reinforcement 110 to increase stability in the area of the outer folds, as can be seen in particular from FIG. 6 of the drawing.
  • the wire reinforcement can also be omitted in the case of a correspondingly stable bellows.
  • the tube 10 is initially cylindrical, starting from the outlet opening 1, and then tapered in the region 100 in the direction of flow.
  • the float 3 is formed in one piece on the tube 10, the bellows 11 being tightly connected to a cylindrical extension 35.
  • the float 3 is formed in two parts, an air chamber 33 being provided below a partition and a flood chamber 34 being provided above the partition, as can be seen in particular from FIG. 10 of the drawing.
  • the flood chamber 33 is bounded by an outer ring wall 30 and an inner ring wall 31 formed by the tube 10.
  • Throttle openings 310 are also provided in the inner ring wall 31, which establish the connection from the flood chamber 34 into the interior of the tube 10, as can be seen in particular from FIGS. 10 and 12.
  • the air chamber 33 is likewise delimited by the outer ring wall 30, while the delimitation takes place in the inner region by the bellows 11.
  • a rod 4 is provided coaxially with the tube 10, which is guided axially displaceably in the cover 21 in a pot-like bush 45 on the one hand and on the other hand extends through the tube 10 and thus simultaneously forms a guide for the float 3.
  • two diametrically opposite transverse arms 40 are formed above an end face 300 of the float 3, with which the float 3 can be flooded by an axial displacement.
  • two diametrically opposite limiting arms 42 are provided at the lower end of the linkage 4. The limiting arms 42 can be adjusted in their axial position on a thread 48.
  • the maximum sinking depth of the float 3 can be limited with the aid of parallel webs 32 formed on the float 3.
  • a detachable flange 46 is provided on the linkage 4 at the upper end region and is inserted after the linkage 4 has been inserted into the bushing 45.
  • the socket 45 is also held in the plug position in the cover 21 with snap tongues 450.
  • a spring 43 is arranged in the bush 45 coaxially to the linkage 4 with the flange 46 and is supported on the one hand on the bottom of the bush 45.
  • a cup-like pusher 44 is inserted, which is detonated by means of latching tongues 440 in axial grooves 451 of the socket 45 and is guided in the socket position 45 to be axially displaceable to a limited extent.
  • the pusher 44 has a bush 441 running coaxially in the inner region, the end face of which bears against the upper edge of the flange 46.
  • an extension piece 47 can be connected in a rotationally fixed manner to the linkage 4, a partial area of the extension 47 protruding from the pusher 44 and having a flag 470.
  • the two limiting arms 42 point in the same direction as the flag 470, so that the respective rotational position of the limiting arms 42 can be seen from the outside by the user.
  • the limiting arms 42 are formed on a hub 420 in which a threaded bore 421 is formed, as can be seen in particular from FIGS. 16 and 17.
  • the thread 48 here has a certain stiffness, so that an unintentional rotation of the limiting arms 42 to the flag 470 is excluded.
  • a smooth-running thread can also be used, in which case a lock nut must also be provided for fixing in the specific rotational position.
  • the float 3 with its flood chamber 34 and the air chamber 33 is made together with the tube 10 in one piece from plastic in an injection molding process.
  • the socket 45 and the pusher 44 can also be produced inexpensively from plastic in an injection molding process.
  • the drain valve described above works as follows: 4, the liquid container 2 of a sanitary water flushing device is filled up to the liquid level 20 from a float-controlled filling valve - not shown in the drawing.
  • the float 3 is held by the air chamber 33 and the flood chamber 34, in which there is no water, with its end face 300 and the outlet opening 1 above the liquid level 20.
  • the linkage 4 is in a rotary position in which the limiting arms 42 come to rest against the parallel webs 32 of the float 3 in a lowered position, so that in this rotary position of the linkage 4 only partial emptying of the amount of liquid present in the liquid container 2 is possible.
  • the pusher 44 must be pressed from its neutral axial position against the force of the spring 43 in the direction of the liquid container 2, as a result of which the linkage 4 is axially deflected and the float 3 is submerged by the transverse arms 40 .
  • Water now flows into the flood chamber 34, so that the float 3 sinks and the liquid can run through the outlet opening 1 into the flushing line, the slightly conical design in the region 100 of the tube 10 additionally giving a force in the direction of the bottom 22 of the Liquid container 2 acts.
  • the force results from the pressure difference of the water column over the projected area and the water column inside the bellows 11. In addition, there is the friction of the liquid on the wall of the pipe 10.
  • the float 3 and thus also the outlet opening 1 sink in the direction the limiting arms 42.
  • the limiting arms 42 come to rest against the parallel webs 32, the lowering of the outlet opening 1 is ended.
  • the flood chamber 34 is emptied through the throttle openings 310, so that the buoyancy of the float 3 is increased accordingly, and the float 3 with its end face 300 formed on the ring wall 30 reappears from the liquid level 20, as shown in FIG. 4 of the drawing.
  • the user should turn the linkage 4 with the extension 47 and the flag 470 by 90 °, as can be seen in particular from FIG. 8 of the drawing .
  • the two limiting arms 42 are positioned parallel to the parallel webs 42, so that during the flushing process, the float 3 can completely immerse into a sump in the bottom 22 and permit complete emptying.
  • the outer ring wall 30 has an outer edge 330 at the lower area, with which the float 3 touches down in the bottom position.
  • the float 3 receives an increased buoyancy again, so that the outlet opening 1 with the float 3 floats above the liquid level 20 and brings the drain valve into its shut-off position.
  • the liquid container 2 is then filled to the liquid level, as shown in FIG. 4. The user can then initiate a new flushing process.
  • the pusher 44 is with his shown retracted position with which a rinsing process is triggered when the liquid container 2 is filled, as shown in Fig. 4.
