According to the utility model, the safety valve of the colloid battery is independent, the whole safety combined valve is separated from a middle cap, such that it is possible to eliminate adverse effect due to the safety valve in production process, so as to prolong normal service life of the battery and improve use safety of the battery to protect a device and the environment.
Description
Technical field
The utility model relates to a kind of independent secure group valve of lead acid accumulator, is particularly useful for gelled lead acid battery.
Background technology
For the lead acid accumulator of sealing, safety valve is a necessary mounted component.Safety valve plays adjusting and the inside and outside action of pressure of limit battery, when the inside battery gas flow surpasses certain value (representing with atmospheric pressure value usually), promptly when inside battery air pressure is elevated to certain value, vent valve is opened automatically, discharge gas, valve-closing prevents that air from entering inside battery then, and the assurance battery can be used safely.The effect of safety valve is similar on the pressure cooker of knowing with people.
For the employed safety valve of traditional gelled lead acid battery, consistent with the employed safety valve of lean solution formula lead acid accumulator, promptly emergency valve seat and battery middle cover are one.This mode is comparatively suitable for lean solution formula lead acid accumulator, but then has many drawbacks for gelled lead acid battery:
Colloid is easy to pollute emergency valve seat when 1, adding glue, after adding glue and finishing, needs to drop into great amount of manpower and clear up emergency valve seat.If clear up not thorough, there is the emergency valve seat surface in residual colloid, safety cap and emergency valve seat contact-making surface frictional force increase, when inside battery air pressure is elevated to standard unlatching pressure value, safety valve can not normally be opened and emit gas, and causes safety valve to lose efficacy, and this moment, cell internal pressure was excessive, the easy bulging of battery, thereby shorten battery life greatly.
2, emergency valve seat exposes outside the battery middle cover, in whole production, is subjected to outside destroy generation defective easily and causes the safety valve sealing bad, and safety valve is opened to press greatly and descended, and the safety valve unlatching frequently makes the battery dehydration too fast, shortens battery life.
The utility model content
At above-mentioned present situation; the utility model provides a kind of gelled lead acid battery secure group valve, and this secure group valve is used for gelled lead acid battery, can prolong the normal useful life of battery; can improve the fail safe that battery uses again, reach the purpose of protection equipment and environment.
The technical solution of the utility model is achieved in that gelled lead acid battery secure group valve, comprise safe valve bonnet, safety cap, air filter piece and emergency valve seat, emergency valve seat is provided with gas passage, safety cap covers at the outlet of gas passage, safe valve bonnet is connected with emergency valve seat and safety cap is covered between safe valve bonnet and the emergency valve seat, safe valve bonnet is provided with exhaust outlet, and air filter piece is between safety cap and exhaust outlet.
The gap that 0.3-0.5mm is arranged between above-mentioned safety cap and the air filter piece.
Be provided with 2～5 barrier plates that gas passage intercepted into circuitous channel in the above-mentioned gas passage.
The utility model is owing to adopt said structure, be installed on during use battery in cover, when inside battery air pressure does not reach when making the certain pressure value that safety valve opens, safety valve is in closed condition, make to be in sealing state in the battery, the outside batteries air can not enter inside battery.After inside battery air pressure reaches certain value, safety valve is opened, be that safety cap is expanded and valve seat generation gap by jack-up or generation under certain air pressure, make inside battery gas obtain discharging, the gas that discharges simultaneously is by the filtration of air filter piece, after gas filtration come out, discharge by the exhaust outlet of safety valve bonnet.After discharging certain gas, inside battery air pressure reduces, and safety valve resets, and enters closed condition.
The utlity model has following advantage:
1, the utility model colloid battery secure group valve can be used as an independently part, separates with the battery middle cover, and it is extremely convenient to mount and dismount.
2, the utility model does not participate in flowing of battery production process, and in the end one procedure is just loaded onto battery usually, is not easy contaminated.The safety valve working stability is admittedly can prolong the useful life of battery.
The utility model is by the independent design structure of colloid battery safety valve; whole secure group valve is separated with middle cover; eliminate the harmful effect that production process is brought battery safety valve; can prolong the normal useful life of battery; can improve the fail safe that battery uses again, reach the purpose of protection equipment and environment.
