Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. The butterfly valve that can be used for switching control of low pressure pipeline medium refers to a valve whose closing piece (valve disc or butterfly plate) is a disc and rotates around the valve axis to open and close. The butterfly valve is a kind of valve that uses the disc type hoist to and fro rotate about 90 ° to open, close or regulate the medium flow. The butterfly valve is not only simple in structure, small in volume, light in weight, low in material consumption, small in installation size, small in driving torque, simple and rapid in operation, but also has good flow regulation function and closing sealing characteristics. The butterfly valve is easy to be combined with various driving devices, and has good durability and reliability. It is one of the fastest growing valve varieties in recent ten years. Butterfly valves are widely used. The variety and quantity of its use are still expanding, and it is developing towards high temperature, high pressure, large diameter, high sealing, long service life, excellent regulation characteristics, and one valve multi-function. Its reliability and Other performance indicators have reached a high level.
