Water Pressure Test Plug Valve

The water pressure test plug valve designed by Dazhong Valve Group adopts a pressure self-tightening sealing structure, is sealed with a flat ring, and the valve seat is made of stainless steel surfacing. During the hydraulic test, the blocking plate is installed, and the blocking plate is taken out after the hydraulic test, and the hydraulic test can be carried out multiple times.

• Installed on the 300MW boiler superheater outlet, reheater inlet, and outlet steam pipes, as an isolation device during the hydraulic test, remove the internal blocking plate after hydraulic pressure, and use it as a pipeline. When the next hydraulic pressure The blocking plate can be installed again

• The pressure self-tightening sealing structure is adopted, and the branch pipes at both ends are welded.

• It is sealed with a flat ring, and the valve seat is made of stainless steel surfacing.

• Insert the blocking plate during the hydrostatic test, take out the blocking plate after the hydrostatic test, and perform the hydrostatic test multiple times
