Explosion-proof valve, also known as explosion relief valve, is a kind of equipment used to prevent the internal pressure of pressure vessel or pipeline from exceeding the allowable range In industrial production, many equipments and pipelines will be supplied with high pressure gas or liquid. If the internal pressure of these equipments or pipelines is too high, it will cause serious potential safety hazards and even lead to accidents Therefore, the use of explosion-proof valve can effectively protect the safety of equipment and personnel
Explosion-proof valve is mainly composed of valve body, spring, valve seat, valve plate and other parts When the pressure inside the pipeline exceeds the set value, the explosion-proof valve will automatically open to release the pressure to avoid equipment or pipeline Explosion-proof valves are generally installed in pressure vessel piping system or other equipment requiring explosion-proof protection to play a role in safety protection
The working principle of explosion-proof valve is to control the switch of valve plate through the compression and release of spring. When the pressure inside the pipeline exceeds the set value, the spring is opened by the compression valve plate to release the pressure; When the pressure drops to a safe range, the spring returns to its original state, and the valve plate closes and stops releasing the pressure The explosion-proof valve can effectively protect the safety of equipment and personnel in time
Besides explosion-proof valves, there are also some other explosion-proof devices such as sheet covers, etc. They are all designed to ensure that the equipment and pipelines can release pressure in time and safely in case of accidents to avoid accidents Safety first is the most important principle in industrial production. Using explosion-proof equipment is an effective means to ensure the safety of personnel and equipment
Generally speaking, explosion-proof valves play an important role in industrial production, which can effectively protect the safety of equipment and personnel Accidents can be avoided by releasing the excessive pressure explosion-proof valve in the pipeline or container in time to ensure the safe and smooth progress of the production process Therefore, in industrial production, the use of high explosion-proof valves should be checked and maintained regularly to ensure their normal operation and ensure production safety
