Background
The pressure relief valve is also called a safety valve, and is a valve capable of being automatically opened and closed according to the internal working pressure of a system, and is generally arranged on equipment or a pipeline of a closed system to protect the system. When the pressure in the equipment or the pipeline exceeds the set pressure of the pressure relief valve, the pressure relief valve is automatically opened, and the medium pressure in the equipment or the pipeline is ensured to be under the set pressure, so that the safety of the equipment or the pipeline is protected, and accidents are prevented. Existing relief valves typically set a threshold, referred to as the cracking pressure or relief pressure. When the pressure inside the pipe or device is above this threshold, the relief valve will open, allowing excess fluid to drain to reduce the pressure.
