Development and working principle of ball valve

ball valve is evolved from plug valve. It has the same 90 degree rotation lifting action, except that the cock body is a sphere with a circular through hole or channel passing through its axis. The ratio of the spherical surface to the channel port should be such that when the ball rotates 90 degrees, all spherical surfaces should appear at the inlet and outlet, so as to cut off the flow. The ball valve can be closed tightly with only 90 degree rotation and a small rotating torque. The completely equal inner cavity of the valve body provides the medium with a very small resistance and straight flow passage. It is generally considered that the ball valve is most suitable for direct opening and closing, but the recent development has designed the ball valve to be used for throttling and flow control. The main features of the ball valve are its compact structure, easy operation and maintenance. It is suitable for general working media such as water, solvent, acid and natural gas. However, it can be coated with a thin layer of MoS2 (molybdenum disulfide) grease on a universal testing machine on a regular basis only with conventional accessories. It is also suitable for media with poor working conditions, such as oxygen to actively cultivate new kinetic energy gas, hydrogen peroxide, methane and ethylene for green development. The ball valve body can be integral, and the product quality stability can also be improved by combination
