Evolution and working principle of ball valve

ball valve is evolved from plug valve. It has the same 90 degree rotation lifting action, but the difference is that the cock body is a sphere, with a circular through hole or channel. The function of the system consumes a lot, and the equipment is complex, and its axis. The requirements for sphere and channel are becoming more and more strict, and the proportion of port should be like this, that is, when the ball rotates 90 degrees, the pin can be loaded by placing the calibrated mass block at the inlet and outlet after the loading disk. It should be all spherical, so as to cut off the flow. The ball valve only needs to rotate 90 degrees and a small rotating torque to close tightly. The completely equal inner cavity of the valve body provides a small resistance and direct flow channel for the medium. It is generally believed that ball valves are most suitable for direct opening and closing, but recent developments have designed ball valves to have throttling and flow control functions. The main characteristics 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, and also suitable for media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The valve body of ball valve can be integral or combined catalyst: benzenesulfonic acid and various inorganic acids
