Power station pressure test valve USES
Installed in 300 mw, 600 mw boiler superheater outlet, reheater inlet and outlet steam pipe, as the water pressure experiment was carried out in isolation device. After adopting transmission device, hydraulic demolition of internal wall plate, into the training set, used as a pipe, next time when hydraulic load boards.
Power station pressure test valve structure characteristics
1, the valve pressure rating equal to or higher than design pressure and design temperature.
2, valve by E101, ANSIB16.25 JB/T6903, JB/T6440, JB/T6902, JB/T6439, JB/T3595 standards related to design, material selection, fabrication, inspection and acceptance.
3, can adopt the way without gear and worm drive two (see chart).
4, using pressure self-tightening seal structure and bolted bonnet structure in two forms, both ends of branch pipe welding
