Claims

[Scope of utility model registration request]

A gate is provided that can open and close the waterway by lifting and lowering, and within this gate, a hanging girder that can be moved vertically relative to the gate and can be locked to the gate in the vertical direction is provided, and this hanging girder is suspended. A hoisting device is provided for raising and lowering both the hanging girder and a gate secured to the hanging girder, a bypass valve that is opened and closed by a vertically movable valve rod is provided in the gate, and the hanging girder is provided with a bypass valve that is opened and closed by a vertically movable valve rod, providing a hook that engages with the valve stem and opens and closes the bypass valve as the suspension girder moves up and down with respect to the gate;
A hanging iron is provided at the gate rest position at the rising end of the gate, which contacts the hook and presses the hook to open and release the engagement between the hook and the valve stem, thereby closing the bypass valve by its own weight. An opening/closing device for a bypass valve with a gate, characterized by:
