Superhigh pressure impulse safety device Structure

A49Y-PW5414V Superhigh Pressure impulse safety device (H Series) Structure Briefing:

1. The impulse safety device is as shown in the figure, mainly consisted of impulse safety valve, main safety valve, stop valve and throttle valve. Impulse safety valve is a kind of spring safety valve. The impulse safety valve can be adjusted by using the spring to regulate the pressure.

2. The impulse safety valve contains an electromagnet to open and another to close the valve. The actions of the mechanism and the electric appliance are separate and will not affect each other.

3. The main safety valve is as shown in the figure. With a structure of double exhaust, it is mainly consisted of body, cushion valve, piston chamber, disc and other parts. The valve adopts the self tightening and sealed structure. The highter the pressure of the medium is, the better the seal performance becomes. The cushion valve serves as a buffer in the working process of the master relief valve to avoid the damage of the sealed surface and the disc.

4. Both the seat and the sealed surface of the disc of the impulse safety valve are made of hard alloy of cobalt by overlaying welding. Both the seat and the sealed surface of the disc of the main safety valve are made of hard alloy of cobalt by plasma spray welding.

5. The upper part of the impulse safety valve contains an electromagnet to open and another to close off. At ordinary times, the close-off electromagnet may not be electrified, but when the sealed surface of the valve leaks, it can be electrified over a long period of time to make the valve sealed. Or when the mechanical adjusting reseating pressure is excessively low, it can be electrified to help the disc return and procure a higher reseating pressure.

6. The impulse safety only leaves the factory after it has passed the seal and sensitivity tests.
