Metal pressure relief and explosion-proof valve is a new type of waterproof and breathable component.Theconnecting rod structure is compressed by a spring and combined with other materials such as metal and siliconerubber to form a sealed installation part,it can avoid dust, water or other harmful substances. While entering, keepthe pressure balance inside and outside the equipment, it has the advantages of quick pressure relief and explosion-proof,high precision of starting explosion point, automatic reset and continuous use after blasting, stableperformance, simple installation and extended product life cycle.

products are mainly used in the field of battery PACK and other occasions that require waterproof, breathable,explosion-proof pressure relief valves and rapid pressure relief to balance internal and external air pressurebattery pack is simple: the battery is overheated, causing thermal runaway. Of course,there are many reasons foroverheating, such as uneven battery pack temperature and high local temperature; overcharge and overdischargeExternal short circuit, internal short circuit, etc., mechanical causes of external force, collision,extrusion, puncture,water ingress, etc. can also be caused.
In order to solve the impact force caused by thermal runaway and the safety of thermal diffusion, Shangda’sexplosion-proof pressure relief valve can quickly relieve pressure and exhaust when it reaches a certain pressurevalue.
