Description
Technical field
The present invention relates to storage battery safety technical fields, are specially a kind of power lithium battery safety valve.
Background technology
Power lithium battery pool technology is the novel environment friendly energy just occurred in recent years, it is widely used in electric vehicle, it is electronic from
The energy storage in the fields such as driving, wind-power electricity generation, solar power generation, communication, power lithium battery pool technology are in rudiment shape at home
State, lithium battery in charge and discharge process because electronics constantly back and forth migration can generate heat, charge or discharge, shock or failure
Etc. short-circuit conditions caused by factors substantial amounts of chemical gas can all be precipitated, when pressure reache a certain level or internal short-circuit of battery and
The spark of generation will burn to the inflammable gas of precipitation, cause battery explosion, and threat is brought to personal property.
There are mainly two types of the power battery safety devices of some producers production at present：1st, it is made of two kinds of different metals tactile
Point type is connected on using the coefficient of expansion difference of two kinds of metals in the circuit of battery, when battery is put, overcurrent or made overcharging, cross
Flow of metal is disconnected into short circuit to get an electric shock to play the role of protection.This safety valve is also easy to produce fire when electric shock is opened or closed
Flower, makes the inflammable gas of inside battery run into spark and generate hidden peril of explosion；2nd, using diaphragm explosion-proof valve, cell internal pressure is worked as
When reaching certain value, it is explosion-proof to achieve the purpose that rupture pressure disc is broken through decompression by internal pressure, the drawback is that safety valve can not be recovered,
Scrap battery failure.
The shortcomings that in order to improve above two power battery safety devices, one kind of Application No. " 201020282536.4 "
Ball-type safety valve with power lithium batteries including valve deck, valve body, spring, ball valve, sealing ring, can effectively play safety anti-explosive
Effect；A kind of safety valve for high-capacity power lithium battery of another Application No. " 201210468220.8 ", including valve body, valve body
Including upper valve body and lower valve body, safety valve has higher stability and security, simple in structure, production cost is low.
Although above-mentioned two application documents provide the security performance of battery well, can be very good to carry out explosion-proof row
Gas, but it still has the defects of more apparent：No matter whether sufficiently large the gas pressure that inside battery generates is, as long as gas
Body pressure can promote ball valve, and ball valve will be opened, connected with ambient atmosphere, gas is discharged at once, but this can be big
The big air-tightness for reducing safety valve, so as to be impacted in itself to battery.
The content of the invention
It is an object of the invention to provide a kind of power lithium battery safety valve, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the present invention provides following technical solution：

Set, rotor plate 103 can also be driven to reset, re-start closing, rotor plate 103 is obliquely installed, and 103 both ends of rotor plate and
10 madial wall of low-pressure inlet pipe is flexibly connected, and by the setting of rotor plate 103, can be divided to low-pressure inlet pipe 10 for two sections, is led to
Too slow one 8 pairs of gases of qi of chong channel ascending adversely pipe into row buffering, storage.
10 inner cavity of low-pressure inlet pipe is provided with baffle 104 close to 2 one side of air inlet pipe so that waste exhaust gases enter low pressure into
When in tracheae 10, rotor plate 103 can preferably be promoted to be rotated, open the connection with buffering tracheae 1.
The setting of rotor plate in the present invention so that low-pressure gas can be carried out first in release in low-pressure inlet pipe 10
Buffer storage, when pressure reaches certain numerical value, rotor plate 103 rotates so that gas can be entered from low-pressure inlet pipe 10
It buffers in tracheae 1.
As one preferably, substrate 131 is connected with out gas spring 123 away from 134 one side of inlet valve, goes out in gas spring 123
Vent plug 122 is connected with out, goes out vent plug 122 and is flexibly connected with 121 side wall of conical pipe, conical pipe 121 is fixedly installed on connecting tube 12
Interior, after in air storing cavity 13 into waste exhaust gases, gas push goes out vent plug 122, carries out gas release, goes out the setting of vent plug 122,
Also buffering, the effect for storing waste exhaust gases can be realized by allowing for air storing cavity 13.
After gas pressure value slowly increases in buffering tracheae 1, gas push inlet valve 134 moves, and gas enters storage
Buffer storage, conical pipe 121 and the setting for going out vent plug 122 are carried out in air cavity 13 so that the gas in air storing cavity 13 is reached in pressure
During to certain numerical value, vent plug 122 can just be promoted out to move, the gas in air storing cavity 13 is discharged by low pressure exhaust mouth 4,
Low pressure exhaust mechanism is divided into three sections of gas buffer storage parts so that in battery by rotor plate 103 and the setting for going out vent plug 122
Low-pressure gas release will not be directly connected with outside atmosphere.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
