Structure:
1. Wehn the medium pressure rises to the set pressure, the impulse safety valve will open , and the medium will enter into the piston chamber of the main safety valve from the impulse pipe to drive the piston to descend, while the valve automatically open; when the impulse safety valve closes, the disc will automatically close.
2. The sealing surface is made of Fe-Based Cr-Ni Stainless Steel by over-laying welding. Through thermal treatment, the disc has stronger resistance to wear and erosion.
Installation:
1. The main Safety Valve shall be installed vertically at the highest position of the device.
2. The main safety valve shall be fastened upon the gallows, which sustains the back-seat force produced in the steam discharging process of the mains afety valve.
