Technical field
The utility model relates to technical field of lithium batteries, and in particular to a kind of rail traffic lithium battery anti-explosion valve structure.
Background technique
The structure of explosion-proof valve in the prior art is usually: it is equipped with rupture pressure disc in the opening of power battery, it is described explosion-proof
Film is used to for power battery being open and seal；Explosion-proof pin is equipped with outside rupture pressure disc, the explosion-proof pin has pyramid tip, rupture pressure disc
Pyramid tip there is a certain distance and the above-mentioned rupture pressure disc of face from rupture pressure disc；The gas generated in power battery can cause to prevent
The expansion of quick-fried film, as power electric pool gas constantly increases, pressure is also increasing, and rupture pressure disc just constantly expands,
When rupture pressure disc is expanded into the pyramid nib contacts with explosion-proof pin, explosion-proof pin just punctures rupture pressure disc, and then rupture pressure disc occurs to break
It splits, so that the gas in power battery is just discharged to outside power battery, the air pressure of power battery interior is also just with disappearance, institute
It just can not be exploded with power battery, to also avoid the generation of dangerous situation.
Above-mentioned explosion-proof valve can be played due to the gas pressure intensity for preventing power battery from generating by inside increases to a certain extent and be sent out
The effect of raw explosion, but there is also certain hidden danger.The process that pyramidal point terminal spine breaks rupture pressure disc is: rupture pressure disc is swollen by internal pressure
It is swollen, until piercing out an aperture by syringe needle, but film cannot rupture at this time, only continue to pressurize, aperture is supportted greatly, can just cause to prevent
The rupture of quick-fried film, rupture pressure disc, which has, significantly to be punctured and rupture process；Therefore the pyramid tip of explosion-proof pin contacts with rupture pressure disc and to anti-
Quick-fried film punctures, and the area at the place of being punctured for the incipient stage rupture pressure disc that rupture pressure disc is punctured is very little, only a very little
Hole is not just revealed seldom or substantially in the amount of leakage of this stage power electric pool gas, and hereafter rupture pressure disc will continue to swollen
Swollen, then pyramid tip constantly expands the place's of puncturing area of rupture pressure disc, and the gas in power battery is just smoothly revealed
To outside power battery；If gas pressure intensity increases quickly in power battery, and has little time to reveal, then in the incipient stage punctured
Still there is the possibility exploded, consequently, it is possible to situation of causing danger.Therefore, the above-mentioned explosion-proof valve using pyramid tip syringe needle is also
A possibility that cannot completely avoiding power battery from exploding because of the increase of internal gas pressure.
Meanwhile above-mentioned rupture pressure disc can only be disposable, and the service life is short, and it is at high cost, need to take a significant amount of time maintenance.
