What is the function of a ball valve?


The function of a ball valve is to control the switching and adjustment of fluids

Ball valve is a fluid control valve that controls the flow of fluid by rotating the ball. The main function of a ball valve is to control the switching and adjustment of fluid to ensure normal flow of fluid in the pipeline. The advantages of ball valves are their simple structure, easy operation, and the ability to withstand high pressure and high temperature. In the industrial field, ball valves are widely used in industries such as petroleum, chemical, power, natural gas, and mining. They are used to control the flow rate, pressure, temperature, and direction of fluids. Ball valves are also widely used in fields such as sewage treatment, air conditioning systems, and water treatment systems. In household pipelines, ball valves can effectively prevent water pipe rupture and leakage, protecting the safety of household property. In addition, the cut-off function of a ball valve is formed by the metal sphere pressing against each other between plastic valve seats under the action of a medium (float ball valve).

The opening and closing part of a ball valve is a circular ball with a hole, which uses the ball core to rotate back and forth around the axis of the valve stem by 0-90 ° to achieve the purpose of opening or closing the valve. The sealing surface of a ball valve is usually in a closed state with the spherical surface, so it is not easily eroded by the medium, easy to operate, and has a simple and compact structure. It can be used in working conditions with water, natural gas, acid, solvents, etc.
