High temperature and high pressure power station gate valve
High temperature and high pressure power station gate valve
Pressure and temperature refer to JB / t3595 ANSI B16.34
2. Main pressure level of high temperature and high pressure power station gate valve
Nominal pressure 200250320
Working pressure P 55 100 V, P 55 140 V, P 55 170 V
3. Advantages of high temperature and high pressure power station gate valve structure
1. Pressure self tightening seal is adopted, and both ends of valve branch are welded.
2. The valve seat and valve sealing surface adopt cobalt based carbide plasma spray welding, which has good wear resistance and scratch resistance.
3. The valve rod is treated by corrosion resistant nitriding, which has good corrosion resistance and scratch resistance.
4. Relevant standards of high temperature and high pressure power station gate valve
