METHOD FOR OPERATING THE CLOSING MECHANISM OF A FLOAT-CONTROLLED BUTTERFLY VALVE OF A SINK CHAMBER FOR RINSING A LIQUID STORAGE SPACE, AND DEVICE FOR CARRYING OUT THE METHOD

摘要

1. Method of activating a locking mechanism of a float-controlled shut-off flap of a flushing chamber for flushing a liquid storage space, in which the float, arranged preferably in the area of the low point of the floor of the storage space or an area upstream and downstream from the storage space and having a float arm and a float body, activates the locking mechanism of the shut-off flap in the essentially emptied state of the storage space or of the area upstream or downstream from the latter, characterized in that, when the space in which the float is located is emptied, a lowering movement of the float for activating the locking mechanism is prevented and the movement of a tripping means is used to release the preset float arm for activating the locking mechanism.
