Description

TECHNICAL FIELD

[0001] The utility model relates to pressure relief valve technical field, concretely is a kind of pressure relief valve of convenient concealment installation. BACKGROUND

[0002] The function of pressure relief valve is to automatically release excessive pressure when the pressure in equipment or pipeline exceeds the set safety range, to ensure the safety of equipment and pipeline. Its principle is based on pressure sensing mechanism, and pressure control is realized by internal spring and piston system or similar structure. Specifically, when the system pressure is lower than the set value, the pressure relief valve remains closed state, to ensure that the medium in the system does not flow out at will. Once the system pressure exceeds the set value, the pressure sensing mechanism in the pressure relief valve will trigger, so that the valve automatically opens, allowing fluid to escape temporarily, thereby releasing excess pressure. When the pressure drops to an acceptable level, the pressure relief valve will reseal, stopping the flow of fluid, and restoring the closed state of the system. This precise pressure control mechanism ensures that the equipment and pipeline are always in a safe and controllable state, effectively preventing damage caused by excessive pressure. The set pressure of the pressure relief valve can usually be flexibly changed by adjusting the spring tightness to adapt to different application scenarios. In general, as an important safety device, the pressure relief valve plays a crucial role in protecting equipment and pipelines from accidental damage. The pressure relief valve with concealed installation is a specially designed valve, and its main feature is that it can better hide the installation components after installation, avoiding being randomly disassembled or damaged.
