Working principle and practical function of ball valve
The working principle of the ball valve is to rely on the rotary valve to make the valve unblocked or blocked.
Ball valve switch light, small size, can make large caliber, reliable seal, simple structure, easy maintenance, sealing surface and spherical surface often closed state, not easy to be eroded by medium, widely used in various industries.
The ball valve can only be closed with 90 degrees of rotation and very small torque. Perfectly equal valve body cavity provides a very small and direct flow passage for the medium. It is generally believed that ball valves are most suitable for direct opening and closing operation, but the development of ball valves has recently been designed to make them throttling and controlling flow. The main characteristic of the ball valve is its compact structure, easy operation and maintenance. It is suitable for water, solvent, acid and natural gas. It is also suitable for the medium with bad working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or modular.
