Pneumatic hard seal butterfly valve structure and working principle

Pneumatic butterfly valve seal butterfly valve installed in the diameter direction of the pipe. In the butterfly valve body cylindrical channel, the disc-shaped disc rotates about the axis, the rotation angle is between 0 ° ~ 90 °, when rotated to 90 °, the valve is fully open state card. Pneumatic butterfly valve seal is simple, small size, light weight, only a few components. And just turn 90 ° to quickly open and close, easy to operate, while the electric valve has good fluid control features. When the butterfly valve is fully open, the thickness of the disc is the only resistance to the flow of the medium through the valve body, so the pressure drop across the valve is small and therefore has good flow control characteristics. Butterfly valve seal and metal seal two types of seal. Flexible sealing valves, seals can be embedded in the body or attached to the butterfly plate around. If the butterfly valve is required to be used as a flow control, the main choice is the correct size and type of valve. The structural principle of the butterfly valve is especially suitable for making large diameter valves. Butterfly valve not only in the oil, gas, chemical, water treatment and other general industry has been widely used, but also used in thermal power station cooling water system.
