Understand the working principle and application of pneumatic ball valve

Pneumatic ball valveOperation principle and application
Pneumatic ball valve is evolved from the plug valve, and the plug valve with a rotation of 90 degrees is different, the plug body is a sphere, there is a round through hole or flow through its axis. Its working principle is to open or close the valve by rolling the valve core.
Pneumatic ball valve switch light weight, small size, can be made of large diameter, tight sealing, simple structure, convenient repair. The sealing surface and the spherical surface are often in a closed condition, not easy to be corroded by the medium, and have been widely used in many occupations.
Pneumatic ball valves and plug valves are the same type of valve, as long as the closed part is a sphere, the sphere rotates around the center line of the valve body to open and close the valve.
Pneumatic ball valve is mainly used for pipeline, cutting speed, distribution and change the flow direction of the medium.
The advantages of pneumatic ball valve
The fluid resistance is small, and the resistance coefficient is equal to the length of the same pipe section.
2. Simple structure, small size and light weight.
3, ball valve sealing surface information is widely used in plastic products, with outstanding sealing performance, widely used in vacuum system.
4, the utility model is convenient to operate, the opening and closing speed is fast, from full open to full close rotation only 90 degrees, easy to remote control.
5. Convenient repair, simple structure of pneumatic ball valve, movable sealing ring, convenient disassembly and replacement.
6. When the steel ball and the valve seat are completely opened or closed, the sealing surface of the steel ball and the valve seat is isolated from the medium. Medium through the period, the valve sealing surface will not wear.
7, a wide range of applications, the way small to a few millimeters, large to a few meters, from high vacuum to high pressure can be used.
8, pneumatic ball valve power source for gas, generally 0.2 ~ 0.8MPa pressure, relatively safe. If the pneumatic ball valve leakage, compared with hydraulic, electric, gas can be directly discharged, no pollution to the environment, high safety.
9. Compared with manual and turbine ball valves, pneumatic ball valves can be equipped with large caliber (manual and turbine ball valves are generally less than DN300 caliber, and the current pneumatic ball valves can reach DN1200 caliber).
