Abstract
A kind of dynamic lithium battery relief valve, including the valve body being sealably coupled in battery cover board, the upper end of valve body is equipped with tabletting, tabletting is equipped with the inner cavity for the aperture connection valve body that loses heart, the bottom of valve body is equipped with air through hole, it is placed with elastic seal ring sealing partition gas passage in the inner cavity of valve body, forms the lossless bleed structure of over-voltage.The utility model it is excessively high in cell internal pressure but also be not up to explosion value when, elastic seal ring can be extrapolated and is squeezed and deformed by air pressure, temporarily there is gap and no longer separates gas passage in sealing, and gas can leak decompression in time, and elastic seal ring can restore sealing with automatic rebounding after pressure reduction.The utility model it is structurally reasonable, can timely pressure release, it is highly-safe, can repeat pressure release use, avoid the unnecessary failure of battery.Also, relief valve can be sealably coupled in the liquid injection hole of battery cover board, vdiverse in function as the plugging structure after battery liquid-filling, make full use of the space of battery cover board.
Description
Technical field：The utility model relates to a kind of safety relief valves that dynamic lithium battery uses.
Background technique：Dynamic lithium battery is in use if there is abnormal conditions, and internal pressure may be increased rapidly, even
Explosion.In order to improve the safety in utilization of battery, generally requires and safety relief valve is installed on battery cover board.But common peace
Full relief valve mostly uses explosion-proof membrane structure, and the price of rupture pressure disc is high, can only be disposable, is easy to puncture during producing and using
Failure, for internal pressure increase but also be not up to explosion value the case where, rupture pressure disc can not timely pressure release, battery be easy rouse becomes
Shape causes the unnecessary failure of battery.Also, the battery cover board region relatively limited for area, is specially arranged safety relief valve
It needs to occupy certain position, is easy to influence space rational deployment.
Summary of the invention：In view of the deficiencies of the prior art, the utility model provide in a kind of use can pressure release in time it is dynamic
Power lithium battery relief valve.
The utility model includes the valve body being sealably coupled in battery cover board, and the upper end of valve body is equipped with tabletting, in tabletting
The bottom of inner cavity equipped with discouraged aperture connection valve body, valve body is equipped with air through hole, places in the inner cavity of valve body flexible close
Seal sealing partition gas passage, forms the lossless bleed structure of over-voltage.
The utility model it is excessively high in cell internal pressure but also be not up to explosion value when, air pressure can extrapolate elastic seal ring
It is squeezed and deformed, sealing temporarily gap occurs and no longer separates gas passage, and gas can leak decompression in time, elasticity after pressure reduction
Sealing ring can restore to seal with automatic rebounding.The utility model it is structurally reasonable, can timely pressure release, highly-safe, Ke Yichong
Multiple pressure release uses, and avoids the unnecessary failure of battery.Also, relief valve can be sealably coupled in the liquid injection hole of battery cover board,
It is vdiverse in function as the plugging structure after battery liquid-filling, make full use of the space of battery cover board.
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
Detailed description of the invention：Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the perspective cross-sectional schematic diagram of embodiment.
Fig. 3 is that embodiment installs and uses status diagram.
Specific embodiment：As shown in Figure 1 to Figure 3, valve body 1 is sealably coupled in battery cover board 7, can actually be sealed
It is connected in the liquid injection hole 8 of battery cover board 7, as the plugging structure after battery liquid-filling, makes full use of the space of battery cover board 7,
Without occupying special position.The upper end of valve body 1 is equipped with tabletting 2, and tabletting 2 is equipped with the aperture 3 that loses heart and is connected to the interior of valve body 1
The bottom of chamber, valve body 1 is equipped with air through hole 4, and the sealing partition gas passage of elastic seal ring 5 is placed in the inner cavity of valve body 1,
Form the lossless bleed structure of over-voltage.
The present embodiment is equipped with boss 6 in the intracavity bottom of valve body 1, and air through hole 4 runs through boss 6, and elastic seal ring 5 surrounds
Outside boss 6, it is more reasonable to construct in this way, and assembly is more convenient.The aperture 3 that loses heart can have multiple, be evenly distributed on the side of tabletting 2
Edge, pressure release effect are good.
Under normal circumstances, elastic seal ring 5 can seal inside battery with 1 inner cavity favorable elasticity of valve body, and partition gas is logical
Road.When cell internal pressure is excessively high, elastic seal ring 5 can be extrapolated and is squeezed and deformed by air pressure, seal temporarily failure, pressed gas
It can be leaked decompression by air through hole 4 and discouraged aperture 3 in time.After pressure reduction, 5 automatic elastic of elastic seal ring is replied,
Sealing restores to come into force, and battery and relief valve can continue to use.
