Description
Technical field
The utility model belongs to explosion-proof technology field, particularly relate to a kind of on battery to discharge the battery anti-explosion valve of the gas produced in charge and discharge process.
Background technology
The rechargeable battery of nearly all type all can produce gas more or less in the process of discharge and recharge, these gases are harmful to battery, if discharged from battery not in time, the shell of battery can be burst after inner air pressure reaches certain value, make battery failure, quick-fried spray or explosion phenomenon can be produced time serious, the person of user of service and property are damaged.Need a kind of can by the excessive air release produced inner in battery charge and discharge process to outside, battery anti-explosion valve that structure is simple, easy for installation.
Utility model content
The utility model provides a kind of structure simple, easy to install for solving in known technology the technical problem that exists, exhaust, the battery anti-explosion valve that explosion-proof effect is good.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is: the explosion-proof ball that battery anti-explosion valve comprises top cover, bleeder screw and is positioned between the two, top cover is provided with 2 to 4 steam vents, bleeder screw inside is provided with exhaust passage, outer wall is provided with screw thread, and top cover is fixed on bleeder screw; Top cover surrounding is provided with for fixing edge, and steam vent is located at the junction of this edge and closure body; Explosion-proof ball is quality of rubber materials, multidiameter structure, and its butt end is against on top cover, its taper end is against on the exhaust passage of bleeder screw; Bleeder screw is connected with the nut turned for spanner etc.
Advantage of the present utility model and good effect are: owing to adopting above-mentioned design, structure of the present utility model is simple, easy to install.Unique explosion-proof ball and exhaust passage, vent design make the exhaust of explosion-proof valve, explosion-proof effect good.
