Ball valve development evolution and the working principle of ball valve is evolved by the cock valve. It has the same rotate 90 degrees to action, different is the cock body is ball, a round hole or channel through its axis. Spherical and opening ratio should be such, that is when the ball rotate 90 degrees, in the inlet and outlet should be completely present spherical, thereby blocking flow. 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 hydraulic fitting manufacturer resistance is very small, straight flow channel. Usually do think ball is 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.
Ball valve working principle and practical effect of the working principle of ball valve is love by rotary valve to keep the valve open or closed. 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 and plug valve is belong to one type of valve, only its closure is a ball, the ball around the center line of the body as a rotation to achieve a kind of open and close the valve. Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Ball valve is widely used in recent years a new type of valve, it has the following advantages: small fluid resistance, the resistance coefficient with section of equal length. Simple structure, small volume, light weight. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system. Easy to operate, open and hydraulic fitting supplier close quickly, from open to close just rotate 90 °, is advantageous for the remote control. Convenient maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient. In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
