Technical field
The utility model is related to cell art, specially a kind of explosion-proof valve of lithium dynamical battery.
Background technology
Explosion-proof valve plays very important effect on the safety problems such as battery explosion are prevented.And the processing of explosion-proof valve in itself
Technique is a technological difficulties, and domestic only several enterprises could autonomous production at present.Due to needing to play the work of valve
With specific requirement can realize explosion under defined air pressure, can not reveal or rupture before air pressure as defined in reaching, at present
The explosion-proof valve of in the market is difficult to play a part of valve under regulation air pressure in use.
Utility model content
The purpose of this utility model is to provide a kind of explosion-proof valve of lithium dynamical battery, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical scheme：A kind of explosion-proof valve of lithium dynamical battery, including
Cover plate, the top of the cover plate has from left to right riveted positive terminal and negative terminal, and the top surface of the cover plate opens up passage,
Offered around the corresponding cover plate of the passage and rupture pressure disc, the top of the rupture pressure disc are bonded with neck, the neck
Safety valve is bonded with, the surface of the safety valve offers through hole, and the neck bottom is with forming safe air chamber, institute at the top of cover plate
Safe air chamber is stated to connect with the inside of battery by airway tube.
It is preferred that, a kind of explosion-proof valve of lithium dynamical battery of rupture pressure disc is divided into three layers, a kind of lithium dynamical battery of top layer
Explosion-proof valve and a kind of explosion-proof valve of lithium dynamical battery of bottom are anti-corrosion layer, and a kind of explosion-proof valve of lithium dynamical battery in intermediate layer is gold
Belong to film layer.
It is preferred that, a kind of explosion-proof valve thickness of lithium dynamical battery of rupture pressure disc is 0.3 centimetre.
It is preferred that, a kind of inner hollow of the explosion-proof valve of lithium dynamical battery of safety valve, a kind of lithium dynamical battery of through hole
Explosion-proof valve and a kind of lithium dynamical battery of rupture pressure disc explosion-proof valve at the top of connect.
Compared with prior art, the beneficial effects of the utility model are：Collection gas is renewed by setting air chamber to reach
Effect, by setting rupture pressure disc, neck, safe air chamber and through hole, reached to be formed under defined air pressure and be fully sealed
State, when reaching the maximum gas pressure born, the gas of rupture pressure disc explosion inside battery is discharged outside battery by through hole and safety valve,
The effect of protection battery is reached.
