Description
Technical field
The present invention relates to battery technology field, seals snifting valve more specifically to one kind, the invention further relates to one
Storage battery of the kind with above-mentioned sealing snifting valve.
Background technology
Storage battery is a kind of device that chemical energy is directly translated into electric energy, mainly by positive plate, minus plate, electrolyte,
Battery container and cover board are formed.
Electrolyte is the important configuration resource of storage battery, when storage battery occurs inversion, drops when fortuitous event, is easier to make
Into the leakage of electrolyte.
Simultaneously as storage battery produces heat in charging process, electrolyte volatilizees because heated produces gas-vapor mix,
The pressure in battery can increase at this time, when pressure, which reaches a certain level, to be discharged, it may occur that expansion explosion, is easier to cause peace
Full accident.
It is current this area skill to realize the security protection to storage battery in conclusion how to avoid the leakage of electrolyte
Art personnel technical problem urgently to be resolved hurrily.
The content of the invention
In view of this, it is an object of the invention to provide one kind to seal snifting valve, to avoid the leakage of electrolyte, so that real
Now to the security protection of storage battery.
Another object of the present invention is to provide a kind of storage battery with above-mentioned sealing snifting valve, to avoid electrolyte
Leakage, so as to fulfill the security protection to storage battery.
In order to achieve the above object, the present invention provides following technical solution：
One kind sealing snifting valve, including：
Valve seat with cavity, is provided with the exhaust hole connected with the cavity on the valve seat；
The valve body being arranged in the cavity, the valve body have fluid passage, the input end of the valve body and the valve
Seat is tightly connected；
Sealing separates the fluid passage and the flexible glue steam venting cap of the cavity, and the valve is covered in outside the flexible glue steam venting cap
The port of export of body, when the Fluid pressure in the fluid passage reaches default exhaust steam pressure, the flexible glue steam venting cap can produce
Life makes the elastic deformation that the fluid passage is connected with the cavity.
Preferably, in above-mentioned sealing snifting valve, the input end of the valve body is interference fitted with the valve seat and passes through annular
Colloid layer is tightly connected.
Preferably, in above-mentioned sealing snifting valve, the first sealing ring and the second sealing ring are provided with the valve seat outer circumferential surface.
Preferably, in above-mentioned sealing snifting valve, the valve seat is provided with outer connection screw thread section.
Preferably, in above-mentioned sealing snifting valve, the valve body includes input end cylindrical section, port of export cylindrical section and connection institute
The changeover portion of input end cylindrical section and the port of export cylindrical section is stated, the input end cylindrical section outside diameter is justified more than the port of export
The outside diameter of cylinder section.
It can be seen from the above technical scheme that sealing snifting valve provided by the invention includes the valve seat with cavity, valve
The exhaust hole connected with cavity is provided with seat；The valve body being arranged in cavity, valve body have fluid passage, the input end of valve body
It is connected with valve base sealing；Sealing separates the flexible glue steam venting cap of fluid passage and cavity, and the outlet of valve body is covered in outside flexible glue steam venting cap
End, when the Fluid pressure in fluid passage reaches default exhaust steam pressure, flexible glue steam venting cap, which can produce, makes fluid passage and sky
The elastic deformation of chamber connection.
It is installed in application, snifting valve will be sealed first on the cover board of storage battery, and makes the import and electric power storage of fluid passage
The electrolyte cavity connection in pond.
In above-mentioned sealing snifting valve, when the Fluid pressure of fluid passage is less than default exhaust steam pressure, flexible glue steam venting cap with
The port of export sealing of valve body coordinates；So, when being inverted, dropping when non-artificial situation generation, fluid passage is in
Closed mode, so as to the leakage of electrolyte is avoided, so as to fulfill the security protection to storage battery.
The sealing function of flexible glue steam venting cap is additionally, since, ambient atmos can be prevented to enter in storage battery, also improved close
Seal effect.
Meanwhile when storage battery produces heat in charging process, and electrolyte by thermal evaporation because being produced gas-vapor mix, electricity
Pressure in pond can increase, and gas-vapor mix enters fluid passage by the input end of valve body, when the fluid pressure in fluid passage
When power reaches default exhaust steam pressure, flexible glue steam venting cap produces elastic deformation, and gas-vapor mix can be from the flexible glue steam discharge of elastic deformation
The gap formed between cap and valve body is discharged to cavity, finally discharges the gas-vapor mix of generation by exhaust hole, avoids
Pressure increase in battery, and then the explosion triggered because gas-vapor mix produces pressure is avoided, so as to fulfill to storage battery
Security protection.
Present invention also offers a kind of storage battery, including cover board, further includes the sealing snifting valve being arranged on the cover board,
The sealing snifting valve is any of the above-described kind of sealing snifting valve, since above-mentioned sealing snifting valve has the effect above, is had above-mentioned
The storage battery of sealing snifting valve has same effect, therefore repeats no more herein.
Preferably, the storage battery is start and stop storage battery.
Brief description of the drawings
