Actual role of pneumatic flange ball valve
The principle of stainless steel pneumatic ball valve is to rely on rotary valve love to make the valve open or blocked. Pneumatic ball valve is light and compact, can be made into a large diameter, reliable sealing, simple structure, easy maintenance, sealing surface and spherical surface often closed, not easily eroded by media, and widely used in various industries.
Pneumatic flange ball valves are mainly used in pipelines to do fast cutting, distributing and changing the flow direction of the medium. Pneumatic ball valve is a new valve that has been widely used in recent years. It has the following advantages:
1. The fluid resistance is small, and its drag coefficient is equal to the length of the same length.
2. Simple structure, small size, light weight.
3. It is compact and reliable. At present, the sealing surface material of the ball valve is widely used with plastics and has good sealing performance. It has also been widely used in vacuum systems.
4. Easy to operate, fast opening and closing, as long as the rotation from 90 degrees from full open to fully closed, easy remote control.
5. Easy maintenance, pneumatic ball valve structure is simple, the seal ring is generally active, removal and replacement are more convenient.
6. When fully open or fully closed, the sealing surfaces of the ball body and the valve seat are isolated from the medium. When the medium passes through, the sealing surface of the valve will not be eroded.
7. Wide range of applications, from small to several millimeters in diameter, up to a few meters in size, from high vacuum to high pressure can be applied.
Pneumatic three-piece ball valve has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, as well as people's daily lives.
