Structural principle of butterfly valve（2）

Structural principle

The structural length and overall height of butterfly valves are small, with fast opening and closing speeds, and good fluid control characteristics. The structural principle of butterfly valves is most suitable for making large-diameter valves. When it is required to use butterfly valves for flow control, the most important thing is to correctly select the specifications and types of butterfly valves, so that they can work properly and effectively.

 

Working principle

Butterfly valve is a type of valve that uses a disc type opening and closing element to rotate back and forth about 90 ° to open, close, or regulate medium flow. Butterfly valves not only have simple structure, small volume, light weight, low material consumption, small installation size, small driving torque, simple and fast operation, but also have good flow regulation function and closing sealing characteristics. They are one of the fastest developing valve varieties in the past decade. 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 multifunctional. Its reliability and other performance indicators have reached a high level.
