Ball valve, the standard GB / T21465-2008 "Valve terminology" is defined as: opening and closing parts (spheres) driven by the stem, and around the axis of the stem for the movement of the valve, the ball valve it has a 90 degree rotation action, For the sphere, with a circular through hole or passage through its axis. Mainly used for cutting off or connected to the pipeline in the medium, can also be used for fluid regulation and control, which hard sealed V-ball valve V-shaped core and surfacing carbide alloy metal seat between the strong shear Cutting force, especially for fiber, micro-solid particles and other media. The multi-ball valve in the pipeline not only can be flexible control of the media confluence, diversion, and flow of the switch, but also can turn off any channel and the other two channels connected. This type of valve in the pipeline should generally be installed horizontally. Ball valve classification: pneumatic ball valve, electric ball valve, manual ball valve. The ball valve only need to rotate 90 degrees of operation and a small turning torque can be closed tight. Ball valve is most suitable for the switch, cut off the valve to use, V-type ball valve. In the western developed countries, the use of ball valves is increasing year by year. In China, ball valves are widely used in oil refining, long-distance pipeline, chemical, paper, pharmaceutical, water, electricity, municipal, steel and other industries. The national economy occupies a pivotal position.
