[0002] Valves are control components in fluid conveying systems, with functions such as shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest shut-off valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. There are many types of valves, including gate valves, shut-off valves, plug valves, ball valves, butterfly valves, needle valves and diaphragm valves.

[0003] A ball valve is a valve whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid regulation and control. When in use, impurities in the water adhere to the inner wall of the ball valve. An automatic cleaning structure is installed in some ball valves. The automatic cleaning structure is mainly installed on the inlet and outlet sides of the ball valve to automatically brush away impurities adhered to the inner wall of the ball valve.
