Ball valve is evolved from the plug valve, its opening and closing parts as a ball, using the ball to rotate 90 degrees around the axis of the stem to achieve the purpose of opening and closing, the difference is that the cock body is a ball, with a circular through hole or channel through its axis. The ratio of the sphere to the passageway should be such that when the ball is rotated 90 degrees, the inlet and outlet should be completely spherical, thus cutting off the flow.
The role of ball valve in the pipeline is mainly used to cut off, distribute and change the direction of media flow, designed into the V-shaped opening ball valve also has good flow regulation function.
Ball valve is not only simple in structure, good sealing performance, but also in a certain nominal range of small volume, light weight, less material consumption, small installation size, and driving torque is small, easy to operate, easy to realize rapid opening and closing, is one of the fastest developing valve varieties in recent decades. Especially in the United States, Japan, Germany, France, Italy, West, Britain and other industrial developed countries, ball valves are widely used, the variety and number of use is still continuing to expand, and to high temperature, high pressure, large mouth, high sealing, long life, excellent regulatory performance and a valve multifunctional direction, its reliability and other performance indicators have reached a higher level, And has partially replaced Gate Valve, Globe Valve, Regulating Valve.
