[0002] The butterfly valve, also known as the flap valve, is a simple regulating valve that can be used for the switch control of low-pressure pipeline media. The butterfly valve refers to a valve with a disc as the closing part, which rotates around the valve axis to achieve opening and closing. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays a role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or regulating. The butterfly valve is a valve that uses a disc-shaped opening and closing part to reciprocate about 90° to open, close or adjust the flow of the medium.
