Definitions

  • the invention relates to a cistern drain valve with a main valve body, which can be lifted off its seat by the triggering actuation of an auxiliary valve by means of an actuating device as a result of a negative water balance in an associated relief chamber.
  • Such a fitting is known for example from DE-A-26 09138.
  • the top of the main valve body provided there forms the lower boundary of a relief chamber.
  • a flow channel in which the auxiliary valve is arranged leads from the relief chamber into the cistern outlet.
  • the trigger actuation With the first actuation of the filled cistern, the trigger actuation, the auxiliary valve is opened.
  • the water running out of the relief chamber creates a negative water balance in it.
  • the main valve body lifts off its seat.
  • the present invention has for its object to provide a drain valve of the generic type, in which the flushing process initiated can be interrupted by a second actuation. This interruption actuation should be able to be carried out with the existing actuation device.
  • the additional auxiliary valve which can be opened at least for a short time by interrupting the actuating device, achieves a positive water balance in the relief chamber in the sense of the closure of the main valve body and also maintains it until the main valve body is finally closed.
  • This configuration enables the purging process to be interrupted prematurely, even with a high level of operating convenience, since the actuation forces and strokes can be kept low and the interruption actuation takes place in the same way as the trigger actuation.
  • the switching device for controlling the auxiliary auxiliary valve can in particular also be a binary coaster.
  • the patent claim 5 is a special binary coaster, which allows comparatively small actuation strokes and can be switched over in its unactuated state even by particularly low forces with regard to its end position. This embodiment of a binary coaster is considered in itself to be inventive.
  • valve 1 and 2 show a drain valve with its actuating rod 1 protruding from the box lid. This is firmly connected to the valve bell 2, which is supported on the box bottom by means of the prestressed lateral springs 3.
  • valve bell 2 In the valve bell 2 there is the upwardly movable main valve body 4, which closes both the lower main valve and the central auxiliary valve 8 when the box is filled and ready for rinsing (FIG. 1).
  • the top of the main valve body 4 and the valve bell 2 delimit the relief chamber 6.
  • the auxiliary valve 8, which closes the flow channel between the relief chamber 6 and the cistern outlet 5, is formed by a sealing washer inserted into the main valve body 4 and the end flange of the actuating rod 1.
  • the auxiliary auxiliary valve 9 In the upper wall of the relief chamber, the auxiliary auxiliary valve 9 is arranged, which cooperates with a wall opening kenden float flap 11 is formed. Its flow cross section is larger than that of the auxiliary valve 8.
  • the float flap 11 is located on the left arm of the control lever 10, the bearing pin 15 of which is firmly connected to the valve bell 2. On the right arm there is a shock entering the relief chamber 6! 12 and in the middle the control arm 13.
  • the switching device 13, 14 has the effect that the end position of the control lever 10 which is encountered in each actuation is pivoted into the opposite end position. In the unactuated state, the control housing 14 does not hinder the control arm 13, so that the control lever 10 - depending on the direction of the forces acting on it - either remains in the end position reached after actuation or is pivoted back into the opposite end position.
  • Fig. 1 the starting position of the drain valve is shown when the box is filled and ready for rinsing.
  • the main valve and the auxiliary valve 8 are closed. Due to the buoyancy of the float flap 11, the auxiliary auxiliary valve 9 is opened, whereby the control arm 13 assumes its right end position. With the trigger actuation, the control arm 13 moves relative to the control housing 14, which pivots it into its left end position.
  • the auxiliary auxiliary valve 9 closes. Since the auxiliary valve 8 opens at the same time, the water balance in the relief chamber becomes negative.
  • the main valve body 4 lifts off its seat and the flushing process begins.
  • the float flap 11 can also be moved into its closed position without forced control by the switching device 13, 14.
  • it is to be designed in such a way that, despite its driving force, it is torn with the flow through the auxiliary valve 8, which inevitably also occurs at the auxiliary auxiliary valve 9. This will be described in more detail later.
  • Fig. 2 shows the drain valve after the trigger actuation during the flushing process.
  • the pressure difference acting in the closing direction on the auxiliary auxiliary valve 9 is maintained, so that the float valve 11 remains closed despite its buoyancy. If there is no interruption actuation, the main valve body 4 only closes after the contents of the box have expired. The water flowing in via the filling valve is then dammed up again. When the water level exceeds the float flap 11, its buoyancy provides for the return of the control lever 10 to the starting position shown in Fig. 1, so that the box is ready for washing again.
  • an interruption actuation causes the relative movement between the control housing 14 and the control arm 13 again. This is therefore pivoted back into its right-hand end position.
  • the auxiliary auxiliary valve 9 opens.
  • the plunger 12 presses the main valve body 4 down. Theoretically, this is not necessary, it only serves to support the closing movement and can easily be limited to the initial area of the closing stroke. However, this means that the main valve body 4 gets even more into the suction of the flushing water flowing off and its floating force is better overcome by the downward flow forces.
  • the decisive factor for the premature closing of the main valve body 4 is the opening of the additional auxiliary valve 9. Since its flow cross-section is larger than that of the still open auxiliary valve 8, the required positive water balance is established in the relief chamber 6. This is retained even if the auxiliary valve 8 and the auxiliary auxiliary valve 9 close synchronously with the return stroke of the actuating rod 1.
  • Responsible for this are not only the larger flow cross section of the auxiliary auxiliary valve 9, but also the flow cross sections, which are small but always present, and which are provided with the guide gap between the main valve body 4 and the valve bell 2.
  • the plunger 12 which can be moved into the relief chamber 6 with the interruption actuation must bring about the full closing stroke of the main valve body 4. Because of the lack of hydraulic closing support, a higher tappet force is required to overcome the buoyancy of the main valve body 4.
  • the switching device 13, 14 can also be taken over for this embodiment if the bearing journal 15 carrying the control arm 13 is arranged in a stationary manner and the control housing 14 is movably arranged with the actuation.
  • the switching device 13, 14 can, for. B. be a special binary coaster, which requires a comparatively small actuation stroke, and which exerts no forces on the control lever 10 in the unactuated state. It is described below with reference to FIGS. 3 and 4.
  • Fig. 3 the symmetrical control arm 13 (corresponds to the symbolic control arm 13 of Figs. 1 and 2) is shown in its right end position in a solid line. Its journal 15 moves with each actuation relative to the likewise symmetrical fixed control contours (corresponds to the control housing 14 in FIGS. 1 and 2).
  • the lever arms 17 are each attached via elastic connecting zones 16, each carrying the right control pin 19 and the left control pin 20 at the upper end. These work together with the fixed control edges 21 and their run-on slopes 22.
  • the center arm 23 carries at the upper end the control pin 24, which cooperates with the fixed control edges 25 and their run-up slopes 26.
  • the arms carrying the control pins are each elastic perpendicular to the plane of the drawing, so that the run-off slopes do not constitute an obstacle.
  • This end position is the starting position shown in solid line in FIG. 4 for the subsequent return stroke of the actuation and thus the bearing pin 15.
  • the control pin 24 slides upward behind its control edge 25 and locks the left end position of the control arm 13.
  • the right control pin 19 releases from its control edge 21 and springs back into its original relative position to the control arm 13.
  • the left control pin 20 slides onto the run-up slope 22, the upright right-hand boundary edge of which takes over the locking of the swivel position before the control pin 24 leaves its control edge 25.
  • the end position of the return stroke is shown in dashed lines in FIG. 4.
  • the left control pin is locked behind the control edge 21.
  • control pins are not hindered by the fixed control contours in the respective end positions when the binary coaster is not actuated.
  • the control arm 13 can therefore be pivoted back into its original starting position even without a renewed double stroke by minor forces acting from outside, which only have to overcome the bearing friction of the pin 15. This is shown by the unfilled arrows in FIG. 4.
  • the binary coaster can be modified such that the control arm 13 is pivoted into its opposite end position only by hydraulic forces when the trigger is actuated. These hydraulic forces are effective insofar as the flow that begins with the actuation of the trigger by the auxiliary valve also inevitably occurs at the auxiliary auxiliary valve and moves the float valve in the closing direction.
  • a fixed control edge 18 can be arranged, which is shown in FIG. 3 as a dotted line. It acts on the control pin 20 and initiates the left pivoting of the control arm 13.
  • Such a simplified switching device 13, 14 can therefore dispense with the right and middle control arm and the fixed control contours interacting with them in comparison to the complete binary coaster.
  • valve bell 2 and the actuating rod 1 are structurally separate from one another. However, they are fixed against each other by a compression spring 27, the pretension of which is stronger than that of the pretensioned lateral springs 3.
  • the auxiliary auxiliary valve 9 'leading to the relief chamber 6 is replaced by the flange 28 arranged on the actuating rod 1 and by the inner collar cooperating with it Valve bell 2 formed. Furthermore, the auxiliary float 29 is guided in the area of the relief chamber 6 'on the actuating rod 1, the lower outer diameter of which is somewhat larger than the diameter of the inner collar 30 in the central bore of the main valve body 4.
  • the triggering operation is carried out in the usual way. If only the restoring force of the lateral springs 3 is overcome, but not the spring 27, the auxiliary auxiliary valve 9 'remains closed. The opened auxiliary valve ensures a negative water balance in the relief chamber 6 and the main valve body 4 opens. These sequences of movements are shown in FIG. 5.
  • Fig. 6 shows the interrupt operation.
  • the restoring force of the spring 27 must be overcome so that the auxiliary auxiliary valve 9 'opens.
  • the water balance in the relief chamber 6 becomes positive and moves the main valve body 4 downward in connection with the flow forces acting increasingly in the closing direction.
  • This is followed by the auxiliary float 29, which is pressed by hydraulic forces onto the inner collar 30 of the float piston 4 and thus blocks the flow through the still open auxiliary valve 8.
  • the positive water balance is maintained until the drain valve is finally closed even if the auxiliary auxiliary valve 9 'closes earlier than the auxiliary valve 8 during the return stroke of the interruption actuation.
  • This is again ensured by the additional flow cross sections between the outer diameter of the main valve body 4 and the inner wall of the valve bell 2. They are significantly larger than the comparatively narrow guide gap between the auxiliary float 29 and the actuating rod 1.
  • auxiliary valve 8 With the final completion of the drain valve, the auxiliary valve 8 is also closed.
  • the Auxiliary float 29 moves upwards because of its buoyancy, since the pressure drop originally acting on it can be compensated for via its central guide gap. The cistern is now ready for the next actuation.
