Anti-explosion waterproof breathable valve

Abstract

The invention relates to an explosion-proof, waterproof and breathable valve, which comprises a valve body, a cover body, a waterproof and breathable film, and an elastic dome. A sliding ring assembly is set in the chamber, and a pressure relief hole is arranged on the side wall of the valve body or the cover body. , a waterproof rubber ring is fixed on the end face of the sliding ring assembly. The waterproof and gas-permeable membrane of the present invention will not be punctured, and the waterproof and gas-permeable membrane returns to a normal state after the excessive internal pressure is released. At the same time, since the dome is used as the elastic part for the position restoration of the internal components, the sensitivity and smoothness of the waterproof and breathable membrane, the main ring, the pressure ring and the inner ring in the process of moving outwards under the pressure of the internal pressure of the equipment are improved, ensuring The inside of the device and the pressure relief hole can be accurately connected to realize the release of pressure, which is safer and more reliable. The entire valve can be designed to be thinner and smaller, and it is more convenient to apply to equipment with limited installation space and high installation requirements.

Description

Technical field [0001] The invention relates to the field of explosion-proof, waterproof and breathable, in particular to an explosion-proof, waterproof and breathable valve. Background technique [0002] At present, in the fields of vehicle batteries, solar energy, and new energy on the market, most of them use a one-time piercing of the waterproof, breathable and explosion-proof membrane to release the gas in the internal space to achieve the effect of explosion protection. But this method also brings other hidden dangers in the process of solving explosion protection. First, the use of a one-time puncture prevents the product from blasting, but the diaphragm after the puncture has water leakage and needs to be replaced in time. The maintenance cost and difficulty of the product are relatively high; second, the product releases internal space gas, which needs to reach A certain pressure will pierce the diaphragm, which will result in greater pressure but not reaching the punct...

But this method also brings other hidden dangers in the process of solving explosion-proof

First, one-time puncture is adopted. Although the product is prevented from blasting, the punctured diaphragm has water leakage and needs to be replaced in time. The product maintenance cost and replacement difficulty are relatively high; second, the product releases the gas in the internal space and needs to reach Only a certain pressure will puncture the diaphragm, which will lead to a high pressure but not a punctured state, making the critical state where the diaphragm is not completely pierced, and the user cannot detect it in time, which brings the risk of water leakage
