Design and manufacture GB/T12234 ASMEB16.34
Structure length JB/T3595
Interface connection size JB/T3595 GB/T12224
Inspection and test JB/T3595 MSS SP61
High temperature and high pressure power station gate valve
High temperature and high pressure power station gate valve
Pressure and Temperature Reference JB/T3595 ANSI B16.34
2. Main pressure level of gate valve of high temperature and high pressure power station
Nominal pressure 200, 250, 320
Working pressure P 55 100V, P 55 140V, P 55 170V
3. Advantages of gate valve structure of high temperature and high pressure power station
1. Pressure self-tightening seal is adopted, and the two ends of the valve body branch are welded.
2. The valve seat and valve sealing surface are made of cobalt-based hard alloy plasma spray welding, which has good wear resistance and scratch resistance.
3. The valve stem is treated by corrosion-resistant nitriding, which has good corrosion resistance and scratch resistance.
4. High temperature and high pressure power station gate valve related standards
