A butterfly valve, also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve which is opened and closed by rotating around a valve shaft, wherein a closing member (a valve clack or a butterfly plate) is a disk. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The pipe mainly plays a role in cutting off and throttling. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved.
