Abstract
The utility model provides a gas piece relief valve for battery is strained to bilayer, includes the circular safety valve housing of upper and lower two -layer step form, the last circular inside groove that is equipped with of safety valve housing, the lower part is equipped with an inner tube as the exhaust passage in the inside groove, and the inner tube upper end is equipped with the lip type valve, and the first gas piece of straining is equipped with on lip type valve upper portion, and the first gas piece of straining clamps in the inside groove top, and the inner tube lower extreme is equipped with the second and strains the gas piece, the safety valve housing lower floor step outside is the helicitic texture, there is the bayonet socket more than 1 in the safety valve housing upper strata step top outside. The utility model discloses a but the bilayer is strained gas piece secondary and is strained acid, filters the acidizing fluid in the gas, prevents that the acidizing fluid from congealing the corruption to the battery in the battery surface, has also avoided battery acid leakage's false appearance simultaneously.
Description
Technical field
This utility model be related to battery technology field and in particular to a kind of bilayer air filter piece accumulator relief valve.
Background technology
At present lead-acid accumulator protection valve is made up of the additional lip type rubber valve of one layer of air filter piece, and battery is in discharge and recharge
During when internal pressure exceedes relief valve maximum valve opening pressure gas battery can be discharged by relief valve, this when is singly
Possibly filter out the acid solution in not clean gas by one layer of air filter piece of relief valve.Once acid solution is coagulated in valve body surface, will affect
The outward appearance of battery, causes the illusion of battery leakage acid.
Content of the invention
This utility model aims to overcome that the above-mentioned not enough of prior art provides a kind of bilayer air filter piece accumulator to use
Relief valve, has prevented the illusion that battery leaks acid in exhaust process.
The technical solution of the utility model is: includes upper and lower two-layer step-like circular safety valve chest, on safe valve chest
Be provided with a circular inner groove, described inside groove middle and lower part be provided with one as exhaust passage inner core, inner core upper end is provided with lip type valve, lip type
Equipped with the first air filter piece, the first air filter piece is installed in inside groove top on valve top, and inner core lower end is provided with the second air filter piece；Described safety
It is helicitic texture outside valve chest lower floor step, the cooperation of relief valve and battery uses threaded；Described safe valve casing
Body upper strata step top outer has the bayonet socket of more than 1.
It is equipped with rubber washer at described safe valve chest upper and lower two-layer step handing-over circumference.
The quantity of described bayonet socket is 4, is evenly distributed in the outer circumference of safe valve chest upper strata step top.
Described first air filter piece upper surface and relief valve housing upper surface level, it is to avoid the interference with battery cover plate.
Described second air filter piece lower surface and relief valve housing bottom lower surface level.
The beneficial effects of the utility model are: this utility model using double-deck air filter piece can secondary acid filtering, filter gas
In acid solution, prevent acid solution from coagulating the corrosion to battery in battery surface, it also avoid simultaneously battery leakage acid illusion.
Brief description
Fig. 1 is axonometric chart of the present utility model.
Fig. 2 is profile of the present utility model.
Specific embodiment
As shown in figure 1, upper and lower two-layer step-like circular safety valve chest 4, safe valve chest 4 is provided with a circular inner groove,
It is helicitic texture outside safe valve chest 4 lower floor's step；The cooperation of relief valve and battery uses threaded.Safe valve casing
It is uniformly distributed 4 bayonet sockets in body 4 upper strata step top outer circumference, be easy to relief valve to be screwed into from battery and back-out.
As shown in Fig. 2 the step-like safe valve chest 4 of upper and lower two-layer, safe valve chest 4 is provided with a circular inner groove, inside groove
Middle and lower part be provided with one as exhaust passage inner core, inner core upper end is provided with lip type valve 2, plays the effect of valve opening valve closing.On lip type valve 2
Portion is installed in inside groove top equipped with the first air filter piece 1, the first air filter piece 1, and inner core lower end is provided with the second air filter piece 5；First air filtration
Piece 1 setting height(from bottom) is less than safe valve chest 4 upper surface；Avoid the interference with battery cover plate.Second air filter piece 5 setting height(from bottom) is less than
Safe valve chest 4 bottom lower surface；It is helicitic texture outside safe valve chest 4 lower floor's step；The cooperation of relief valve and battery is adopted
It is threaded.It is equipped with rubber washer 3 at safe valve chest 4 upper and lower two-layer step handing-over circumference, play the effect of sealing.
Battery in charge and discharge process when produce gas be more than relief valve maximum cracking pressure when will by air filter piece 5 to
Outer discharge, during gas is discharged, air filter piece 5 can filter acid solution in gas, a small amount of overflow acid solution with gas one
Rise and wash lip type valve 2 open and discharge to outside relief valve, this when, air filter piece 1 just served the effect of second filtration acid solution, kept away
Exempt from sour pearl and condense upon valve outer surface.
