Description

Technical Field

[0001] The utility model relates to the technical field of reservoir drain valves, in particular to a medium-sized reservoir drain valve. Background Art

[0002] Reservoirs in water conservancy and hydropower projects typically require a venting structure to cope with various operational situations. A vent pipe is typically installed at the bottom of the reservoir dam. The vent pipe's primary functions are to drain the reservoir and irrigate farmland, and to provide water for downstream urban life. A vent valve is used to control the opening and closing of the vent pipe. For example, a reservoir vent pipe valve replacement auxiliary device, as shown in Chinese Patent Publication No. CN213740827U, shows a steel sleeve with a flange fixed to its open end. A vent pipe and a water pipe are connected to the other end of the sleeve. A water-stopping rubber ring is fixed to the outer edge of the flange's end face facing away from the steel sleeve. The water-stopping rubber ring presses against the outer end face of a water hole on a platform on the inner wall of the dam. A grille and a vent pipe are fixed within the vent hole. A vent valve is provided at the end of the vent pipe that extends beyond the dam.

[0003] However, when replacing the vent valve, the water inlet end of the vent pipe needs to be blocked before the vent valve can be replaced. This process is not only time-consuming and labor-intensive, but also easily affects the drainage of the reservoir by the vent pipe, and also affects the domestic water use of downstream cities, thereby causing inconvenience to the replacement and maintenance of the vent pipe valve.
