  • the venting device releases the vent opening as a function of a liquid level surrounding the riser pipe.
  • the drain valve within the liquid container which may be a Spülschacht, is arranged, whereby the required space is significantly reduced.
  • the riser is not only in fluid communication with the liquid level in the liquid container. Rather, the rising liquid level in the liquid container can be used to actuate the venting device. In this way, the drain valve works automatically and reliably.

  • the float may be formed as an inverted cup, which encloses an air cushion with increasing liquid level.
  • the shut-off element has a sealing portion with which the vent opening can be closed. This can improve the sealing function of the shut-off element for closing the vent opening, since the specially designed sealing section is adapted to the vent opening in order to close it in a targeted and reliable manner.
  • a guide is provided on the riser pipe or the shut-off .
  • a guide has the purpose to guide the shut-off element along its actuating path between the locking position and the release position, so that a more reliable function can be ensured.

It has been shown here that the Drain valve even more reliable when the said pressure equalization is established during the transfer of the valve member in its open position.
  • the pressure compensation device comprises a pressure equalization channel and a check valve.
  • a pressure equalization channel which preferably extends between the two ends of the valve member, is a very simple way to establish pressure equalization.
  • the check valve is provided, which strives under the built-up in the riser pressure of the air cushion in the closed position.
  • the non-return valve has the purpose to compensate for any occurring pressure peaks during the expiring rinsing surge and to keep the valve member longer in the open position.
  • the pressure equalization channel can be formed as a longitudinal bore in the valve member. This simplifies the manufacture of the valve member.

  • the float is arranged on the valve member longitudinally displaceable between a shut-off and a Mitaueranschlag for the float. This embodiment allows a production of the individual components with the greatest possible manufacturing tolerances.
  • the float has a driver portion which engages during a driving movement of the float to the open position on the driver stop of the valve member. This ensures a reliable interaction between the float and the valve member.
  • the float has at least one bridging section, which protrudes in particular with respect to the driver portion of the float and lifts the seal in the entrainment movement of the float in the open position.
  • the float can also serve as an actuator for the bridging of the check valve to provide at the moment in which the opening movement of the valve member begins to provide already for a pressure equalization. In this way, the drain valve works very reliable.
  • a liquid container according to claim 11 for the production of surge flushing with one of the previously described drain valves, which is provided to selectively close or release a drain opening of the liquid container. It has proven to be advantageous to equip liquid containers, such as rinsing shafts, with a drain valve according to the invention, in order to provide a surge flushing mechanism in the inflow region of the sewer. Liquid reservoirs with pre-assembled drain valves facilitate installation of the entire device.

In this way, not only the actuation of the valve member is triggered, but also provided the force required to move the valve member by the floating of the float in the liquid level. This makes the proposed method mainly dependent on the liquid level in the liquid container and rising therein.
  • the float actuates a pressure compensation device when triggering the venting, which produces a pressure equalization between the two ends of the valve member of the drain valve. In this way, any existing, unfavorable pressure differences between the sewer located behind the drain opening and the space located in the riser can be compensated, so that the valve member does not automatically return to the closed position due to the unfavorable pressure conditions before the rinse is triggered.

That is, the material of the float portion 9 has a smaller density than the liquid contained in the liquid container 1. In any case, the shut-off 8 is designed as a float or float. Therefore, variants are also conceivable in which the shut-off element 8 is made of a material having a higher density than the liquid present in the liquid container 1, but the formation of the shut-off element 8 as a floating body provides for a floating in the liquid. Conceivable are cup-shaped Embodiments or hollow configurations in which the recesses do not come into contact with the liquid level rising in the liquid container 1 during normal operation.
