Plant basic classification and structure of pneumatic valve

'power station' pneumatic valve special pneumatic valve, also known as power station is mainly used in the thermal power plant all kinds of the pipeline system, cut off or connect pipe medium. Applicable medium: water, steam and other corrosive medium. Power station of pneumatic valve compared with other pneumatic valve products is characterized by high temperature and high pressure, special since the seal design, the higher the pressure, the more reliable seal. Because of performance technology characteristics, operating mode of the special products have formed the characteristics do not replace the other products.

power station pneumatic valve structure advantage. Since the tight seal is adopted, and the branch pipe pneumatic valve body for welding connection at both ends.
。 Pneumatic valve seat, pneumatic valve sealing surface using cobalt-based hard alloy welding or plasma spray welding and become, high temperature resistant, wear resistant, good abrasion resistance.
。 Pneumatic valve rod by corrosion resistance nitriding processing, good corrosion resistance and abrasion resistance.

power pneumatic valve compared with other pneumatic valve products is characterized by high temperature and high pressure, if only from the aspects of pressure is lower than general pneumatic valve, just from the aspects of temperature is lower than than general pneumatic valves. Because of performance technology characteristics, operating mode of the special products have formed the characteristics do not replace the other products.
