Big Discount Spherical Disc Butterfly Valve - Main safety valve – Convista Detail:
This valve is used for power plant boilers, pressure containers, pressure and temperature reducing device and other facilities. It serves to prevent the pressure exceeding the highest allowed pressure value and ensure the safety of the device when working.
1、When the medium pressure rises to the set pressure, the impulse safety valve opens, and the medium in the impulse pipe enters into the piston chamber of the main safety valve from impulse pipe, forcing the piston to descend, and then the valve automatically opens; when the impulse safety valve closes, the disc will also automatically close.
2、The sealed surface is made of Fe base stainless steel by overlaying welding. Through thermal treatment, the wear resistance and anti-erosion of disc is improved.
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 main safety valve.
3、The exhaust pipe shall contain a special aglow to prevent the force of its weight directly applying on the main safety valve. The connecting flange between the main safety valve and exhaust pipe shall eliminate any extra stress.
4、At the lowest point of the exhaust pipe, water drainage shall be taken into consideration to avoid producing water hammer while discharging steam.
