The power station valve synopsis 】 "Power station valve also known as the" plant dedicated valve, the pipeline mainly used in the thermal power plant system, cut off or connect pipe medium. Applicable medium: water, steam and other corrosive medium. Power station valve compared with other valve products is characterized by high temperature and high pressure, the unique 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.
The power station valve USES 】 Welding connection of valve is suitable for the nominal pressure PN16.0 32.0 MPa, working temperature 540 ℃ or less (including P57170V working temperature is 570 ℃) of oil, chemical industry, hydropower and thermal power plant all kinds of the pipeline system, cut off or connect pipe medium. Applicable medium: water, oil, steam, acid medium, etc. Operation mode: manual, gear drive, electric, etc.
Power station valve structure diagram The power station valve structure characteristics 】 (1). Using pressure self-tightening sealing, the valve manifold for welding connection at both ends. (2). The stem by corrosion resistance nitriding processing, good corrosion resistance and abrasion resistance. (3). Sit valve, valve sealing surface using cobalt-based hard alloy plasma spray welding and become, wear resistant, good abrasion resistance.
