pneumatic ball valve is a kind of commonly used control element, it is evolved by the plug valve, with the same the effect of rotating 90 degrees. The difference is that the plug is a sphere body, there is a round hole or through the axis of the channel. This paper mainly introduces the purpose and the advantages of the pneumatic ball valve, hope I can help you better application products. The working principle of the application of the pneumatic ball valve pneumatic ball valve is by changing the valve core valve open or jam. Pneumatic ball valve switch light weight, small size, large diameter can be made, reliable sealing, simple structure, convenient maintenance, the sealing surface and spherical surface are in a closed state, not easily be medium corrosion, has been widely used in various industries. Pneumatic ball valve and plug valve is the same type of valve, only the closing part is a sphere, spheres revolve around the body line, implements a Industrial Valves open and close. Pneumatic ball valve is mainly used for pipe, cutting speed, the distribution and change of flow direction of medium. The advantages of the pneumatic ball valve 1. The resistance coefficient of fluid drag coefficient is equal to the length of the same section. 2. Simple structure, small volume, light weight. 3. Ball valve sealing surface material closed, reliable and has good sealing performance, has been widely used in the vacuum system. 4. The utility model has convenient operation, opening and closing speed, from open to close only 90 ° rotation, the advantages of convenient for remote control. 5. Convenient maintenance, pneumatic ball valve structure is simple, general is mobile sealing ring, it is more convenient to remove and replace. 6. Sphere and valve seat fully open or closed, sphere and Industrial Valves seat sealing surface and the dielectric isolation, medium by less wear of valve sealing surface. 7. Applicable scope wide, small path to a few millimeters, big to a few meters, from high vacuum to high pressure can be used. 8. The pneumatic ball valve power supply for gas, general is 0. 2 to 0. 8 mpa pressure, relative safety. If the pneumatic ball valve leakage, compared with the hydraulic and electric, gas can direct emissions, no pollution to the environment, at the same time has the very high security. 9. Compared with the manual and turbine rotating ball valves, pneumatic ball valve with large-diameter ball valve. ( Manual and generally below DN 300 turbine rotating ball valve diameter, pneumatic ball Industrial Valves diameter can achieve DN 1200. ) Pneumatic ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aerospace, rockets and other departments as well as People's Daily life.
