Ball valve
Ball valves are widely used in oil, gas, coal and ore mining, refining and processing and pipeline transportation systems; in chemical products, medicine and food production systems; in hydropower, thermal power and nuclear power power power production systems; in urban and industrial enterprises water supply and drainage, heating and gas supply systems; in farmland drainage and irrigation systems; in metallurgical production systems An important mechanical product closely related to production and construction, national defense construction and people's life. The ball valve is sealed in all kinds of pipeline systems and is used to cut off or connect the medium flow, so that the medium can be transported to each designated point according to the predetermined procedure.
(1) The flow resistance is small, and the ball valve with full diameter has no flow resistance.
(2) It has the advantages of simple structure, small volume and light weight.
(3) Tight. It has two sealing surfaces, and the sealing surface material of ball valve is plastic, which has good sealing performance and can realize sealing. It has also been used in vacuum system.
(4) It is easy to operate and fast to open and close. From full opening to full closing, only 90 ° rotation is needed, which is convenient for remote control.
(5) Maintenance is convenient, ball valve structure is simple, seal ring is generally movable, disassembly and replacement are more convenient.
(6) When the valve is fully open or closed, the sealing surface of the ball and valve seat is isolated from the medium. When the medium passes through, the valve will not be sealed.
