The use and advantages of pneumatic ball valve are introduced
Pneumatic ball valves are a commonly used control element that evolved from the plug valve with an opposite rotation of 90 degrees measure. The difference is that the stopcock body is a sphere with a circular through-hole or channel through its axis. This article introduces the use and advantages of pneumatic ball valve, hope to help you better use the product.
Pneumatic ball valve use
The working principle of pneumatic ball valve is to dredge or block the valve by rotating the spool. Pneumatic ball valve switch heavy, small size, large diameter, reliable sealing, complex structure, easy to maintain. The sealing surface and the sphere are often closed, not easy to be eroded by the medium, and are widely used in various industries.
Pneumatic ball valve and plug valve belong to the same type of valve. As long as its enclosed part is a sphere, the sphere rotates around the center line of the body to open and close the valve.
Pneumatic ball valve is mainly used for fast cutting, distribution and change the direction of the pipeline medium.
The advantages of pneumatic ball valve
1. Fluid resistance is small, and its resistance coefficient is equal to the same length of pipe section.
2. Complex structure, small volume, light weight.
3. Tight and reliable. At present, plastic is widely used in ball valve sealing surface data, sealing performance is good, also widely used in vacuum debris.
4. Easy to operate, fast switch, from fully open to fully closed only need to rotate 90°, convenient control distance.
5. Convenient maintenance, pneumatic ball valve structure is complex, sealing ring is generally active, assembly and replacement are more convenient.
6. When completely open or completely closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause corrosion of the sealing surface of the valve.
7. Wide range of application, diameter from small to a few millimeters, to a few meters, from high vacuum to high pressure can be used.
8. Because the power source of pneumatic ball valve is gas, the pressure is usually 0.2-0.8mpa, which is absolutely safer. If the pneumatic ball valve leakage, absolute hydraulic, electric, gas can be directly discharged, do not purify the environment, high safety.
9. For manual and turbine rotary ball valves, pneumatic ball valves can be configured with large caliber (manual and turbine rotary ball valves are generally in DN pneumatic ball valves can reach 300 caliber below DN1200 caliber.)
Pneumatic ball valve has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rocket and other departments, as well as People's Daily life.
