Abstract
The utility model discloses an air cap used for an accumulator, which belongs to a battery. The technical problem which is needed to be solved of the utility model is that an air cap used for an accumulator is designed. Insulation property between battery groups and battery storehouses can not be affected when the battery is used for discharging gas. The utility model has the technical scheme that an air cap used for an accumulator comprises an air cap housing and an air cap cover, wherein a clapboard is arranged in the air cap housing, external threads arranged on a step housing body at the lower part of the air cap housing are matched with threads of air outlet holes of the accumulator, at least two cavities which are communicated with each other are arranged in the air cap housing, filter cotton is put into the cavities which are arranged in the air cap housing and cavities are arranged between filter cotton cavities. The utility model is suitable for liquid environment at the periphery of the batteries.
Description
Technical field
The utility model relates to a kind of battery, particularly a kind of storage battery gas cap.
Background technology
The gas cap (vent plug) of existing Alkaline Zinc silver accumulator is a closed elasticity pressure relief, promptly when the air pressure in the Battery body reaches certain pressure, elastic sealing device such as rubber ring in the gas cap, elastomers such as spring are opened release gas automatically, when gas pressure value drops to elastic force less than elastic component, automatically close, it is gas that this structure is only applicable to the battery pack surrounding environment, when battery pack is in liquid environment, the battery pack of using in the bathyscaph of ocean for example, because the gas that cell body produces contains electrolyte, this alkaline electrolyte can reduce the electrical insulation capability between battery pack and battery.
Summary of the invention
The utility model technical issues that need to address design a kind of battery gas cap, and this gas cap can not exert an influence to the insulation property between battery pack and battery compartment when cell row goes out gas.The technical solution of the utility model is, a kind of storage battery gas cap, comprise the gentle cap of gas cap shell, it is characterized in that: be provided with dividing plate in the gas cap shell, the venthole screw thread that the step housing of gas cap shell bottom is provided with external screw thread and storage battery matches, in the gas cap shell, be provided with the cavity that filter pulp is arranged and communicate with each other in two at least, between the filter pulp chamber, be provided with cavity.The utility model is owing to be provided with a plurality of cavitys on the exhaust passage in gas cap, filled material in it with adsorptive liquid, thereby the utility model to have gas-liquid separation effect compared with the prior art good, the reliable advantage of the insulation property between battery pack and battery compartment.
Description of drawings
Accompanying drawing is an axial section of the present utility model.
Embodiment
In conjunction with above accompanying drawing the utility model is elaborated, two stepped holes about in the gas cap shell 1 being, be provided with following plug dish 2 with holes at the lower port place in the hole of getting out of a predicament or an embarrassing situation, its upper port is provided with top plug dish 4 with holes, in topping bar the hole, the gas cap shell is provided with lower clapboard 6 and upper spacer 7, between top plug dish and lower clapboard, be connected with one 5, the tube end and last, cavity 3 between the following plug dish is not communicated with, hole on the upper spacer is communicated with cavity between last lower clapboard, the centre bore of lower clapboard is communicated with the inner chamber of tube 5 and the cavity between last lower clapboard, the wall of tube 5 is provided with the hole, the top, bottom surface of the low groove of dividing plate 9 is provided with an inverted tube 11, be provided with gas cap lid 13 at the upper port place of dividing plate 9, the end face of the dividing plate 9 relative with gas cap shell upper port is provided with the hole and is communicated with cavity between the dividing plate 9 with the upper plenum 8 of gas cap shell and tube 11 respectively, the bottom of tube 11 has the hole and is communicated with the hole that gas cap covers, and is provided with cavity 12 between tube 11 and the gas cap lid.Be placed with filter pulp ventilative and suction electrolyte function in cavity 8 between cavity between the plug dish 3, dividing plate 9 and the upper spacer 7 and the cavity 12 up and down.
