Definitions

  • the invention relates to a drain valve for a cistern, with an auxiliary valve, which has a closure body, after its actuation is the static pressure of the rinse water automatic opening of the main valve causes.
  • a drain valve of this type is known from the prior art DE 2609138 become known.
  • This is the closure body of the main valve an up and down movable piston.
  • At the Piston is attached to a sealing flange, which is when the cistern is full due to the static pressure on the valve seat of the Main valve rests.
  • An upper side of the sealing flange offers is a cylinder space, which after actuation of the Auxiliary valve is relieved of the water pressure.
  • This drain valve has the advantage that it is comparatively low Force can be operated.
  • To trigger a rinsing process is a pressure on the closure body of the auxiliary valve exercised, which opens the auxiliary valve.
  • Cisterns have also been in use for a long time, which also include flushing with a portion of the rinse water, for example 6 liters enable. This saves water on a large scale.
  • the invention is based on the object, the drain valve so that a partial rinse with this is possible.
  • the valve should still have a simple structure own as well as be reliable and easy to maintain.
  • the object is achieved according to claim 1.
  • the control of the Auxiliary valve with a float enables this to be closed Auxiliary valve depending on the water level in the cistern and therefore a partial rinse.
  • Preferably in one Dual flush two swimmers provided in different Heights are arranged. With the bottom float becomes one Full flushing and partial flushing controlled with the upper float.
  • the height of the upper float determines the amount of Rinsing water during partial rinsing.
  • This top float is in its height adjustable, so the desired subset can easily and be set precisely at the same time.
  • a major advantage of the drain valve according to the invention is seen there that the closing noise during a partial flush is significantly smaller than the previous cisterns, that allow a partial rinse.
  • the very annoying blow when closing of the main valve is significantly dampened because the closure body of the main valve is moved by a differential pressure of the water and is therefore completely in the water. The valve body can therefore not suddenly hit the valve seat.
  • a further reduction in the flushing noise can then be achieved if the cistern outlet is horizontal.
  • the exit is direct and a flushing bow, in which usually Noises can be avoided.
  • At least one tie rod provided with the valve body of the auxiliary valve connected is.
  • a float is arranged on this tie rod and by means of a latch or other locking device this tie rod is fixed.
  • the pull rod can now be unlocked released and a flush is triggered.
  • the postponement can be done with little force and enables a mechanical, electromagnetic or pneumatic release. Due to the low power required is a trigger possible with battery operation.
  • FIG. 1 to 6 show a cistern 2 in which a drain valve 1 is attached.
  • the drain valve 1 is actuated with an actuating device only indicated in FIG. 2 3, which is arranged behind an inspection opening 36 and the one mechanical, electromagnetic, hydraulic or can be pneumatic actuation.
  • the in Fig. 2 latch 31 shown in the position shown in Fig. 3 postponed. This shift takes place against the retroactive one Force of a spring 38.
  • the drain valve 1 has a main valve 5 and an auxiliary valve 4 on that near a relatively narrow bottom wall 37 of the box body are arranged.
  • the main valve 5 has a piston 8, on which a Sealing flange 21 is arranged, which has a valve seat 32 cooperates.
  • the piston 8 is horizontal in a valve housing 11 displaceable and in relation to this with an outer circumferential sealing ring 24 sealed.
  • a back 39 of the Piston 8 faces a chamber 23, which in FIG Opening 33 of the housing 11 with an interior 40 of the cistern 2 is connected. When the cistern is full is in the Room 40 and room 23 rinse water.
  • the interior 40 is also via a passage 22 of the housing 11 with a space 41 connected.
  • a front 42 of the piston 8 is this space 41 facing.
  • the position of the piston according to FIG. 4 prevails the same water pressure in both rooms 23 and 41.
  • a compression spring 28 which on a rear wall 43 of the housing 11th is supported, the piston 8 in that shown in Fig. 4 Position held.
  • the main valve 5 is as can be seen closed.
  • the auxiliary valve 4 has a rod-shaped closure body 26 on a lower sealing flange 27 and an upper sealing flange 34 has.
  • a compression spring 29 is shown in FIG. 4 on one Supported web 44 and holds the closure body 26 in the in Fig. 4 position, in which the lower sealing flange 27 rests on a valve seat 20 of a channel 19.
  • the channel 19 leads according to FIG. 4 along and to the bottom wall 37 vertically rising overflow pipe 6, which according to FIG has upper overflow opening 7.
  • the channel 19 is horizontal Outlet opening 45 of an outlet nozzle 9 connected.
