The technical solution of the utility model is:
A kind of novel nickel-hydrogen battery safety device, comprise gas main body 1, capping 2, jack 8 and air leakage hole 9, described jack 8 is located at vent plug main body 1 inside, one end of jack 8 communicates with the air leakage hole 9 of main body 1 bottom, the other end opening of jack 8, described capping 2 closely cooperates with the openend of jack 8 and fixedlys connected, and is provided with in the capping 2 to make jack 8 and the extraneous air vent hole 10 that communicates; Also be provided with spring 5 in the wherein said jack 8, an end of spring 5 connects and air leakage hole 9 offsets and the rubber column 4 of closed air leakage hole 9, leaves the gap between rubber column 4 and the jack 8, and the other end of spring 5 links to each other with capping 2.
Also be provided with pad 3 (this pad can be cancelled, and directly capping is contacted with spring) between capping 2 and the spring 5, pad 3 is provided with and air vent hole 10 corresponding perforates, hinders pore 10 to prevent pad 3.The aperture of perforate is not necessarily identical on air leakage hole 9, air vent hole 10 and the pad 3, if but the aperture unanimity can make the exhaust velocity in each hole identical, and then can increase current-controlled accuracy, so the preferred aperture of this three is identical.
The monnolithic case of vent plug main body 1 is generally upper coarse and lower fine two cylinders stack shape, and vent plug main body 1 thin inserts inside battery, and the top of vent plug main body (by air vent hole 10) communicates with the external world.Air vent hole 10 communicates with jack 8, and rubber column 4 closures by having spring 5 between jack 8 and the air leakage hole 9.When cell internal pressure just often, rubber column 4 tightly is against on the air leakage hole 9 by spring pressure, and battery is constituted sealing.When cell internal pressure surpasses rated pressure, pressure can upwards push up rubber column 4, thereby make the bottom surface in rubber column 4 and the vent plug main body 8 produce the slit, thereby formation gas vent, gas is by this outlet, crack, limit between rubber column 5 and jack 8 leaks in the jack 8 of vent plug inner chamber, is discharged outside the battery by air vent hole 10 at last.Rubber column 4 bottom surfaces were not supported the air leakage hole 9 of vent plug main body when last fully, and the gas in the battery can directly be discharged, and when inside battery air pressure descends, because the pressure of spring 5, rubber column 4 meetings seal with the air leakage hole 9 of vent plug main body 1 again.The utility model is controlled the folding of safety valve by the elasticity of spring, can significantly promote the accuracy of air pressure control, and exhaust velocity.
The beneficial effects of the utility model:
1, traditional a plurality of parts is simplified transformation.The apply materials advantage adopts spring, plastics to simplify for chief commander's structural texture, makes its structure more simple, makes more convenient.
2, the structure that adopts elastomeric material to combine with spring and control, strengthened the accuracy of control inside battery air pressure, when inside battery air pressure reaches certain force value, can rapidly gas have been discharged, effectively prevent battery explosion phenomenon, battery safety is improved greatly.
3, utilization spring, rubber, plastics etc. replace traditional all-metal structure, lower production cost, alleviate battery weight.
This safety valve manufacturing technology has had both safety valve and has controlled plurality of advantages such as the structural texture of degassing function and refining and low production cost accurately, thereby make air pressure safety valve that the unique manufacture of this utilization designs will promote rapidly and use in the production process of Ni-MH battery afterwards, it will have the vast market space in the coming years.
