Factory making Forged Steel Trunnion Mounted Fully Welded Ball Valve - Hydraulic three-way valve for water supply of high-pressure heater – Convista Detail:
Type | Three-way Valve |
Model | F763Y-2500LB, F763Y-320, F763Y-420 |
Nominal Diameter | DN 350-650 |
During normal operation of high-pressure heater of 600 to 1,000MW supercritical (ultra-supercritical) thermal power unit, the main route of the three-way valve at high pressure heater inlet is opened and the bypass is closed. Water supply of the boiler enters the high-pressure heater from the main route before entering the boiler through the three-way valve at high pressure heater outlet.
- The valve body and bonnet adopt fully forged steel structure.
- Sealing type of the valve body and bonnet adopts pressure self-sealing structure.
- Top of the valve bonnet has water injection and drainage holes and the piston is built in the valve bonnet.
- Sealing surfaces of the valve seat and disc adopt Stellite No. 6 alloy spray welding.
- The bypass sealing adopts the sealing structure integrating modified PTFE elastic energy storage ring and perfluoro O-ring.
- The throttle elements in inlet three-way valve bypass and the upper valve seat adopt integrated design and require no additional throttle orifice separately.
