The working principle of pneumatic forged steel ball valve is to make the valve open or blocked by rotating the spool. Pneumatic ball valve switch light, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and sphere are often in a closed state, not easy to be washed by the medium, in various industries have been widely used.
The closing part of the pneumatic forged steel ball valve is a ball, and the ball rotates around the center line of the valve body to achieve the opening and closing of a valve.
Pneumatic forged steel ball valve in the pipeline is mainly used to cut off speed, distribution and change the direction of the flow of the medium. Pneumatic ball valve is a new type of valve, it has the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length.
2. Simple structure, small size, light weight.
3. Tight and reliable, the sealing surface material of the ball valve is widely used in plastic, good sealing, and has been widely used in the vacuum system.
4. Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 degrees, easy to remote control.
5. Convenient maintenance, pneumatic ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
6. When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when it passes through.
7. Wide range of application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
8, because the pneumatic ball valve power source is gas, generally 0.2-0.8MPa pressure, relatively safe. If the pneumatic ball valve leaks, relative to hydraulic, electric, gas can be directly discharged, no pollution to the environment, while having a high safety.
Pneumatic ball valves have been widely used in petroleum, chemical, power generation, paper making, construction industries
