摘要： The present disclosure provides an explosion-proof valve core, an explosion-proof valve, and a box body gas tightness detection clamp, including an explosion-proof valve core, a valve body, and sealing rings. The waterproof gas-permeable explosion-proof valve core of the present disclosure timely discharges high-temperature and high-pressure in a box body, which prevents explosion or reduces damage caused by explosion. An inner sealing ring in the explosion-proof valve is fixed through an inner sealing ring groove, so that a problem of poor sealing caused by easy falling and displacement of the inner sealing ring is solved. A metal protective shell is disposed on an outer side of an explosion-proof valve spring, a problem that the spring is blocked by battery core jets to weaken pressure relief performance when working is solved. The present disclosure further provides the box body gas tightness detection clamp, which is simple to use and operate.
