The introduction of butterfly valve

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. It is one of the fastest growing valve varieties in recent decades. 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.

With the application of chemical resistant synthetic rubber in butterfly valves, the performance of butterfly valves has been improved. Because synthetic rubber has the characteristics of corrosion resistance, erosion resistance, dimensional stability, good resilience, easy forming, low cost, etc., and can choose synthetic rubber with different properties according to different use requirements to meet the operating conditions of butterfly valves.

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 valve can be used to control the flow of various fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It is mainly used to cut off and throttle the pipeline. The butterfly valve opening and closing piece 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 adjustment.
