Description

A kind of battery and its relief valve
Technical field
The present invention relates to battery technology field, more specifically to a kind of battery and its relief valve.
Background technology
The electrolyte of battery is important configuration resource, is inverted, the situation that drops may all cause the leakage of electrolyte.And And battery can produce heat in charging process, electrolyte volatilizees because heated produces gas-vapor mix, causes in battery Pressure can increase, when the pressure value in battery, which reaches, can not discharge to a certain degree, it is possible to create blast.
In summary, the problem of how efficiently solving battery rechargable battery internal pressure excessive explosive, is current sheet Art personnel's urgent problem.
The content of the invention
In view of this, first purpose of the invention is to provide a kind of relief valve, and the structure design of the relief valve can be with The problem of efficiently solving battery rechargable battery internal pressure excessive explosive.Second object of the present invention is to provide one kind Include the battery of above-mentioned relief valve.
In order to reach above-mentioned first purpose, the present invention provides following technical scheme:
A kind of relief valve, including:
Valve body and the valve element for being arranged at the valve inner, and sealed between the valve body and valve element;
The colloid steam venting cap being arranged on the valve body, there is steam discharge seam, the valve core inside on the colloid steam venting cap With with the exhaust passage that connects of steam discharge seam, steam discharge when pressure in the exhaust passage is in the first setting range Sew and strut to form outlet, the steam discharge seam closure when pressure in the exhaust passage is in the second setting range.
Preferably, in above-mentioned relief valve, sealing ring is provided between the valve body and valve element.
Preferably, in above-mentioned relief valve, fluted, the inner side insertion of the sealing ring is opened up on the valve body and valve element In the groove of the valve element, the outside of the sealing ring is embedded in the groove of the valve body.
Preferably, in above-mentioned relief valve, the material of the sealing ring is silica gel or rubber..
Preferably, in above-mentioned relief valve, the valve element is plastic poppet.
Preferably, in above-mentioned relief valve, the valve body is plastics valve body..
Preferably, in above-mentioned relief valve, first setting range is 12-16kpa, second setting range be less than 12kpa。
A kind of battery, including accumulator body and the relief valve being arranged on the accumulator body, the relief valve For the relief valve any one of as described above;
Connected inside the exhaust passage and the accumulator body, the steam discharge slit is into the outlet of the relief valve.
Preferably, in above-mentioned battery, the battery cover of the valve body of the relief valve and the accumulator body welds.
Relief valve provided by the invention includes valve element and valve body.Wherein, valve element is arranged on the inside of valve body, and valve element and Sealed between valve body.Colloid steam venting cap is provided with valve body, i.e. colloid steam venting cap is set on valve body.Have on colloid steam venting cap Steam discharge stitches, and valve core inside has the exhaust passage connected with steam discharge seam, when the pressure in exhaust passage is in the first setting range When steam discharge sew and strut to form outlet, i.e., when the pressure in exhaust passage is in the first setting range colloid steam venting cap can occur Elastic deformation, and then steam discharge sews and struts to form outlet, the gas-vapor mix in exhaust passage is stitched from steam discharge and discharged, with the row of reduction Pressure in vapour passage.The steam discharge seam closure when the pressure in exhaust passage is in the second setting range, i.e., when in exhaust passage Pressure in the second setting range when, colloid steam venting cap resiles, now steam discharge seam closure, it is impossible to have gas or vapour-liquid again Mixture is stitched by steam discharge, realizes the sealing of relief valve.
During using relief valve provided by the invention, the exhaust passage of relief valve is connected with internal storage battery, by relief valve Steam discharge seam connected with battery outer.When the pressure of internal storage battery is in the first setting range, colloid steam venting cap occurs Elastic deformation, and then steam discharge sews and struts to form outlet, the gas-vapor mix in battery is stitched from steam discharge and discharged, to reduce electric power storage Pressure in pond.When the pressure of internal storage battery is in the second setting range, colloid steam venting cap resiles, and now steam discharge stitches Closure, it is impossible to there is gas or liquid-vapor mixture to be stitched by steam discharge again, realize the sealing of battery.From the foregoing, it will be observed that use this hair , can be by relief valve pressure release when the pressure in battery is larger during the relief valve of bright offer, and then avoid battery and fill The problem of cell internal pressure excessive explosive.
In order to reach above-mentioned second purpose, present invention also offers a kind of battery, the battery includes any of the above-described Kind relief valve.Because above-mentioned relief valve has above-mentioned technique effect, the battery with the relief valve also should be with corresponding Technique effect.
