When a fire disaster occurs outside the storage tank, the medium in the storage tank is heated, the volatile gas is greatly increased, and the gas phase space pressure in the storage tank is increased. When the pressure reaches the set opening pressure of the emergency release valve. The emergency release valve starts to work, the valve disc is opened, gas in the storage tank is discharged, the pressure in the storage tank is ensured not to be higher than the opening pressure of the emergency release valve, and the effect of protecting the storage tank is achieved.
The conventional emergency relief valve is assembled from a valve body, a valve disc, and a pressure loading assembly. The pressure loading assembly is typically a weight gravity loaded, spring loaded. The conventional emergency release valve has the following problems:

Second, the conventional spring-loaded emergency release valve uses a compression spring to pressure-load the valve disc, thereby achieving high-pressure opening of the valve disc. However, when the valve disc needs to be opened upwards to reach the rated discharge height, the spring is continuously compressed, and the loading force acting on the valve disc is continuously increased, so that the valve disc is pushed up by the higher pressure in the storage tank, the overpressure in the storage tank is serious, and the overpressure of the spring-loaded emergency release valve is high, so that the discharge capacity of the emergency release valve is affected.
