- pneumatic ball valve Knowledge of pneumatic ball valve

pneumatic ball valve, pneumatic ball valve in f Yu Shiji s with the rapid development of science and technology, pneumatic ball valve have continuous improvement, production and processing product structure in our factory in short time, pneumatic ball valve has rapidly developed into a major pneumatic valve, in the western developed countries, the use of pneumatic ball valve is constantly the rise year by year, in the pneumatic ball valve is widely used in oil drilling oil refining factory pipeline, chemical industry, paper making, pharmacy, food, electric power, steel and other industries, in I occupy important position in national economy. Pneumatic ball valve is mainly used for medium red in river closure, or connect line adjustment also moving valve in the pipeline and ventilation on not only the confluence of flexible control medium, three-channel is linked together, compared with other types of pneumatic valve pneumatic ball valve has the following advantages. A, easy to switch quickly to meet on line there is a requirement for quick opening, fast closing high andao place 2, fluid resistance small, whether it's full size reducing type pneumatic ball valve are all pneumatic valve fluid resistance in the smallest one. Three, reliable pneumatic valve seat seal, ordinary ball sealing ring are tetrafluoroethylene type other plastic better a polymeric material manufacturing, have higher request for seal, soft seal is easier to ensure sealing, metal sealing, < > hard seal structure can bear with the Npa, the Npa, the Npa high pressure can be high temperature ℃ in our daily life. Four, reliable pneumatic valve stem seal, can pour sealing structure with the pneumatic valve stem increases with the increment of medium, the denier pneumatic ball valve open/close the pneumatic valve rod make rotation movement only, and not of deeds lifting movement. Pneumatic valve stem packing is not easy to damage. Sealing of the pneumatic valve stem significantly longer service life. Five, the service life is long, pneumatic device in destructive tests above. Because the sealing parts of pneumatic ball valve is used more is good self-lubrication material of ptfe gas such as materials and pneumatic ball valve, pneumatic valve rod friction and wear are the youngest, ensures the service life of pneumatic valve. Sixth, is widely used. Pneumatic goal diversification not only can be used for manual rotation method, also can operate solenoid pneumatic valve control over long distances. Conveying medium and viscous fluid and conveyor belt of the fiber slurry, dust and solid particles. Installation is simple, pneumatic ball valve of small size light weight, compact structure, can be installed on any position of the line in any direction, at the same time, it is easy to transport and storage.
