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 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) Small fluid resistance, full size of the ball valve is basically no flow resistance.
(2) Simple structure, small volume and light weight.
(3) Compact.It has two sealing surface, and the current ball valve sealing material using plastic, good sealing, can achieve sealing.It has also been used in vacuum systems.
(4) Easy to operate, fast on and off, from full open to full close only rotation 90°, convenient for remote control.
(5) Easy maintenance, simple ball valve structure, sealing ring is generally active, disassembly and replacement are relatively convenient.
(6) When fully open or fully closed, the sealing surface of the ball and seat is isolated from the medium, which will not cause valve sealing when passing through.
