Ball valve working principle and practical effect

The working principle of ball valve is love by rotary valve to keep the valve open or occlusion. Ball valve switch lightweight, small size, can make it big caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries. Ball valve just has to rotate 90 degrees operation and small rotational torque can be closed tight. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Usually do think ball valve * suitable for direct use open and close, but recent development has put a ball valve designed to make it with throttling and control flow. Ball valve itself is the main characteristics of compact structure, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be a whole, also can be combined. Pump valve in our country in 2011, such as machinery manufacturing industry's main income rose 28. 41% of the world's first AP1000 nuclear blast valve in the final hydrostatic test
