Valve controlling type accumulator is enclosed construction, and discharge capacity is little.
Vented cell, different according to accumulator use state, need to open fill cap and keep the skin wet, or carry out battery detecting, simultaneously by fill cap externally Exhaust Gas, therefore, also must fall acid mist to needing the gas filtration of discharging, meeting the requirement of environmental protection; Existing fill cap structure is scattered, and assembling, operation and use are all more loaded down with trivial details.
Utility model content
The purpose of this utility model is to provide a kind of New energy electric automobile-used lead acid accumulator special type fill cap, and structure is simple, easy and simple to handle, effectively can filter acid mist, reduces moisture discharge, extends the moisturizing cycle.
New energy electric described in the utility model automobile-used lead acid accumulator special type fill cap, comprise fluid injection lid, fluid injection lid top arranges upper cover, fluid injection lid bottom cover installs in battery cover liquid injection hole, on cover steam vent be set, arrange air filter piece in upper cover, air filter piece bottom arranges seal cover, and seal cover arranges air-vent; The hinge that upper cover and fluid injection lid pass through side is hinged, arranges sealing ring between fluid injection lid and battery cover.
Described New energy electric automobile-used lead acid accumulator special type fill cap, when needing to detect storage battery or moisturizing, upper cover and fluid injection lid are articulated as one, and directly open upper cover, can not fall down, and after moisturizing, cover upper cover, easy and simple to handle; In battery, acid mist and steam enter air filter piece along air-vent in seal cover, and acid mist is discharged after air filter piece filters; Steam is constantly condensed into water by seal cover, is back in battery, decreases moisture loss before discharging.
Described steam vent arranges 2-10, arranges 4 effects best, is convenient to the gas after filtering and discharges.
Described air-vent can arrange 2-20, general layout 9, and air-vent is evenly arranged better effects if, facilitates steam to condense into water and is back in battery by air-vent, reduces moisture loss.
Described air filter piece is expanded polytetrafluoroethyl(ne air filter piece; Filter acid fog effect is better, prevents the better effects if that steam overflows; Can prevent battery meet naked light time on fire, prevent battery explosion, improve battery safety in utilization.
Described fluid injection lid bottom arranges filter screen, filters, prevent foreign matter from falling into battery, cause damage to battery the liquid injecting battery; Filter screen also may be used for observing liquid level in battery simultaneously, during detection, if liquid level is lower than filter screen, then shows to need filling liquid; Liquid level higher than filter screen, does not then need filling liquid.
Described filter screen set installs in fluid injection lid, and fluid injection lid lower inside arranges step, filter screen arranged outside boss, and boss snaps on step; Filter screen set is contained in fluid injection lid, and simple installation is firm.
Described fluid injection lid is connected with battery cover by buckle; Connect more firm tightr, prevent acid mist from leaking from junction further.
Described sealing ring is caoutchouc elasticity sealing ring, and sealing effectiveness is better.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model structure is simple, easy and simple to handle, by arranging air filter piece, effectively can filter acid mist, avoiding contaminated environment; Meanwhile, can prevent battery meet naked light time on fire, prevent battery explosion, improve battery safety in utilization;
(2) seal cover, air filter piece and upper cover constitute maze-type structure, extend flow of water vapor route, add steam setting time, decrease moisture discharge, extend the moisturizing cycle;
(3) upper cover and fluid injection lid are hinged together, and simplify operation, are easy to open upper cover, filling liquid or detection battery.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model,
Fig. 2 is the structural representation of seal cover.
In figure: 1, upper cover 2, air filter piece 3, seal cover 4, fluid injection lid 5, sealing ring 6, filter screen 7, hinge 8, air-vent.
Embodiment
Below in conjunction with embodiment, the utility model is described further:
As shown in Fig. 1 ~ Fig. 2, New energy electric described in the utility model automobile-used lead acid accumulator special type fill cap, comprises fluid injection lid 4, and fluid injection lid 4 top arranges upper cover 1, fluid injection lid 4 bottom cover installs in battery cover liquid injection hole, and fluid injection lid 4 is connected with battery cover by buckle; Upper cover 1 arranges steam vent, and steam vent can arrange 2-10, and arrange 4 effects best, steam vent is evenly arranged better effects if; Arrange air filter piece 2 in upper cover 1, air filter piece 2 bottom arranges seal cover 3, seal cover 3 is arranged air-vent 8, and air-vent 8 can arrange 2-20, and generally arrange 9, air-vent 8 is evenly arranged better effects if; Upper cover 1 is hinged by the hinge 7 of side with fluid injection lid 4, and arrange sealing ring 5 between fluid injection lid 4 and battery cover, sealing ring 5 is caoutchouc elasticity sealing ring.
