Usually, when the air pressure of the closed system rises excessively, the pressure release valve is opened to release part of the pressure, so that the air pressure of the closed system is reduced, the occurrence of dangerous accidents is prevented, and the working stability of the closed system is ensured.

In the prior art, there are two main types of relief valve structures: spring type and lever type. The spring type means that the sealing of the valve clack and the valve seat is against the acting force of the spring. The lever type is realized by the acting force of a lever and a heavy hammer. With the demand of large capacity, there is also a pulsed relief valve, also called pilot relief valve, consisting of a main relief valve and an auxiliary valve. When the medium pressure in the pipeline exceeds the specified pressure value, the auxiliary valve is opened first, the medium enters the main pressure release valve along the guide pipe, and the main pressure release valve is opened, so that the increased medium pressure is reduced. However, the pulsed relief valve is susceptible to insensitive response, and when the pressure exceeds a set pressure value, the relief valve may not be opened in time.
