Superhigh Pressure Impulse Safety Device(H series)

Superhigh pressure impulse safety device Instruction

This suiperhigh pressure impulse safety device is used for power plant boilers with steam working conditions as: P=13.72MPa, T=540 C. Its main function is to avoid the medium pressure inside the boiler exceeding the allowable value to ensure that the boiler run safely.

Superhigh pressure impulse safety device features:

The impulse safety device is the main safety valve, with auxiliary valve support contained. This device has large discharge ability with convenient adjustment.

Superhigh pressure impulse safety device working principle:

When the medium pressure inside the boiler surpasses the allowable value, the impulse safety valve opens firstly; the steam enters into the piston chamber of the main safety valve, forcing the main safety valve to open; the boiler bengins discharging steam; after the excess pressure has been released, the impulse safety valve closed, stopping the steam entering into the piston chamber of the main safety valve; the main safety valve automatically closes at the reactions of the springs and medium.
