Ball valve door of knowledge
Ball valve door rotates 90 degrees it with the same action, different is the cock body is ball, a circular hole or channel through its axis. Ball valve in the line is mainly used to do door stop, distribution, and change the flow direction of medium, it just has to rotate 90 degrees of operating and small rotational torque can be closed tightly. Ball valve door using the most appropriate do switch, cut off valve, ball valve door but recent development have designed to make it with throttling and control flow, such as v-shaped ball valve gate. Ball valve door itself is the main characteristics of 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 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, widely used in various fields. Ball valve gate valve door can be a whole body, also can be combined. ( Edit this paragraph] Fluid resistance small, full size of ball valve door little flow resistance. Simple structure, small volume, light weight. The compact and reliable. It has two sealing surface, and the widely use of all kinds of plastic ball valve sealing surface of the door materials, good sealing, can realize completely sealed. Have been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close just rotate it 90 & deg; To facilitate remote control. Convenient maintenance, simple ball valve door structure, 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. As ball valves in the process of opening and closing doors have wiped sex, so can be used to bring in the medium of suspended solid particles.
