- pneumatic ball valve Pneumatic pneumatic valve

pneumatic ball valve English name; Pneumatic ball valve, as the name implies, Pneumatic ball valve of Pneumatic ball valve with Pneumatic actuator. Pneumatic actuators execution speed is relatively fast, the fastest switching speed. Seconds/times, so usually also called pneumatic quick cut pneumatic ball valve. Pneumatic ball valve usually configure various accessories, such as electromagnetic air valve, air source treatment sanlian pieces, limit switch, locator, control box, etc. , in order to realize the local control and remote centralized control, pneumatic valve in the control room can control the switch, do not need to run to the field or high altitude and dangerous manual control, to a great extent, save the human resources and time and safety. The application of the pneumatic ball valve, pneumatic ball valve itself, compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, applicable to ordinary work such as water, solvents, acids and gas medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various fields. Pneumatic valve pneumatic ball valve body can be as a whole, also can be combined. The characteristics of the pneumatic ball valve, pneumatic ball valve is mainly used for cutting or on line in the medium, can also be used for flow regulation and control, pneumatic ball valve compared with other types of pneumatic valves, Angle schedule output torque, start quickly, stable and reliable, and is used widely, such as the following several advantages. , fluid resistance small, pneumatic ball valve are all pneumatic valves classification of least resistance of fluid, even reducing pneumatic ball valve, the fluid resistance is small. , thrust bearing, reduce the pneumatic valve rod friction torque, can make the pneumatic valve stem long smooth and flexible operation. , pneumatic valve seat sealing performance is good, use the sealing ring made of elastic material, such as teflon structure is easy to be sealed, and pneumatic ball valve pneumatic valve sealing ability increases as the medium pressure increases. , pneumatic valve rod sealing is reliable, the pneumatic valve stem will only be used as the rotation without lifting movement, pneumatic valve stem packing seal is not easy to damage, and sealing ability increases as the medium pressure increases. , such as ptfe material has good self-lubrication, with ball friction loss is small, so the pneumatic ball valve of long service life. , bottoms type pneumatic valve rod, and pneumatic valve stem head convex order to prevent the pneumatic valve rod, such as pneumatic stem seal damage caused by fire, convex order can also be formed between the pneumatic valve body and the metal contact, to ensure that the pneumatic valve stem seal. , anti-static functions: in a sphere, pneumatic valve, pneumatic valve body between the spring, will be generated switching process of electrostatic export. The advantages of the pneumatic ball valve, pneumatic ball valve in the line is mainly used to do fast cutting, distribution, and change the flow direction of medium. Fluid resistance is small, its resistance coefficient with section of equal length. Simple structure, small volume, light weight. Close and reliable, the pneumatic ball valve sealing surface of materials widely used plastic, sealing good, also has been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close as long as the rotating °, is advantageous for the remote control. Pneumatic valve has simple structure, convenient maintenance, pneumatic ball sealing ring are generally activities, remove the replacement is more convenient. In full open or full close, the sphere and the pneumatic valve seat sealing surface and the dielectric isolation, medium through, can not cause erosion of pneumatic valve sealing surface. Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. 。 Because pneumatic ball valve is a gas that is used by the power source is commonly. - 。 MPa pressure, is relatively safe. Pneumatic ball valve if air leakage, the relative hydraulic, electric, gas can directly discharge, no pollution to the environment, and has higher security. 。 Compared with the manual and pneumatic turbine rotating ball valve, pneumatic ball valve can be large caliber configuration, ( Manual and pneumatic turbine rotating ball valve is generally below DN caliber, pneumatic ball valve DN caliber can be achieved at present. ） Pneumatic ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life.
