Many people do not know the correct working principle of the sewage ball valve!Release time: 2019-01-09 Clicks: 49 times
The structure of the sewage ball valve has obvious advantages. It is developed according to the actual situation in China, and the connection size conforms to national standards. In particular, the sealing ring of the valve has the advantages of high strength, high wear resistance and strong resilience. The fluid resistance is small, the structure is simple, the volume is small, heavy and light, tight and reliable, and the treasure is good. Can achieve complete sealing, has been widely used in vacuum systems. The operator makes the opening and closing fast, and it only needs to rotate 90 degrees from fully open to fully closed, which is convenient for long-distance control. Easy maintenance, simple ball valve structure, seal ring is generally movable, and it is more convenient to disassemble and replace. It is large and used for the flow of pipeline media such as petroleum, chemical industry and steam.
The sewage ball valve adopts high-strength carbon-bonded graphite or seals the valve seat with high-temperature and abrasion-resistant materials such as Juju to increase the service temperature of the valve, which can reach about 300 degrees. The high temperature ball valve adopts an integral valve body and a side-mounted ball valve structure, which reduces the bolted middle flange and reduces the leakage point. The valve seat has high temperature, wear resistance, corrosion resistance, strong resilience, and good self-lubrication. Sewage ball valve is widely used in petroleum, chemical, rubber, papermaking, pharmaceutical and other industries. It can replace globe valve, plunger valve, quick sewage valve for high-temperature water, steam, heat transfer oil and other pipelines and devices.
