Abstract
A double-disk slide valve, the shut-off plates of which are displaceable by means of an actuator rod and which is provided with a bridging pipe having two sealing rings that are in operative engagement with corresponding housing sealing seats of the slide valve housing when the slide valve is in the open position. At least one of the two housing sealing seats rests, by the action of a resilient element, under predetermined pressure against the sealing ring(s) associated with the bridging pipe when the slide valve is in the open position and against the peripheral edge of the shut-off plate(s) when the slide valve is in the closed position.
