One, introduction power station valve
"Special valve power station valve" also known as the power station, line the main fire station for the various systems, cut off or connected to the pipeline medium. Suitable medium: water, steam and other non corrosive media. Power station valves and other valve products than is characterized by high temperature and high pressure, the unique self seal design, the higher the pressure, the more reliable seal. Because of the special technical performance characteristics, conditions of formation of the products can not be replaced by other product characteristics.
Two, power station valve main design specification
Design and manufacture of GB/T12234 ASMEB16.34
The length of the structure JB/T3595
Interface connection size JB/T3595 GB/T12224
Inspection and test of JB/T3595 MSS SP61
The pressure and temperature of the benchmark JB/T3595 ANSI B16.34
Three, power station valve pressure rating
The nominal pressure of 200, 250, 320
Working pressure of P 55 100V, P 55 140V, P 55 170V
Four, power station valve structure
1 the pressure seal, valve pipe ends are connected by welding.
The 2 valve seat, valve sealing surface of valve using cobalt based alloy plasma spray welding, wear resistance, good anti abrasion performance.
3 stem through the corrosion resistance of nitriding treatment, with good corrosion resistance and scratch resistance.
