Abstract

The utility model provides an adjustable valve-control sealed cylindrical lead battery without maintaining, output parts of a positive and a negative pole posts of the battery can be solidified and sealed by polyamide resin in the mode of large range and long distance; a conical valve is arranged in the exhaust vent of a battery cover; an elastic rubber post is arranged on the conical valve; a regulating screw nail is placed on the elastic rubber post and are contacted and abutted with the elastic rubber post; the press to the conical valve from the elastic rubber post can be changed by the regulating screw nail; the air press for opening and closing the valve can be satisfied by the conical valve. The utility model has the advantages that the normal internal pressure of the battery can be ensured, without bringing explosion for damaging electric appliances, the leakage can not happen in the normal lifetime, etc.

Description

Adjustable valve-control sealed non-maintaining cylindrical excide battery

The utility model relates to a kind of battery, especially a kind of adjustable valve-control sealed non-maintaining cylindrical excide battery.

As can the optional position the cylindrical excide battery of closed maintenance free of work the most important thing is definitely can not leak, guarantee simultaneously safety again, could satisfy electric instructions for use, in other words promptly can not leakage, inside battery is worked under the certain pressure of assurance, in case when the improper use air pressure inside surpasses setting, must be able to start open valve decompression, otherwise battery causes blast or damages electrical appliance.

The purpose of this utility model is to provide a kind of adjustable valve-control sealed non-maintaining cylindrical excide battery.

The utility model can be achieved by the following scheme: a kind of adjustable valve-control sealed non-maintaining cylindrical excide battery, comprise shell 1, place positive plate 13 and the pole 7-1 and the lead-in wire 7-2 of shell 1 the inside, negative plate 10 and pole 7-3 thereof and lead-in wire 7-4, just, negative plate paripheral zone one dividing plate 11, sealed cell lid 2, brace 9, be loaded on the negative plate 12 and the positive electrode cap above the battery cover 3 of battery bottom, positive and negative terminals 7-1 at battery, the extension of 7-3 adopts long curing apart from polyamide to seal on a large scale, in the battery cover steam vent, establish a cone valve 6, the valve point downwards, put an elastic caoutchouc post 5 above the cone valve 6, adjustment screw 4 places above the elastic caoutchouc post 5 and touches to elastic caoutchouc post 5, by the pressure of 5 pairs of cone valves 6 of adjustment screw 4 change elastic caoutchouc posts, cone valve 6 is satisfied drive valve and close valve air pressure.

The utility model contrast prior art has following advantage: 1, because be provided with cone valve in the cell row pore, when making the pressure of inside battery surpass setting, can start cone valve, unlikelyly to guarantee inside battery to continue operate as normal set off an explosion, damage electrical appliance; 2, the extension at battery electrode column adopts long curing apart from polyamide to seal on a large scale, guarantees that battery can not leak in ordinary life.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a cone valve structural representation of the present utility model.

Among the figure: 1 is battery case, and 2 is battery cover, and 3 is positive electrode cap, and 4 is that adjustment screw, 5 is that rubber column, 6 is cone valve, and 7 are lead-in wire, and 8 is that polyamide, 9 is brace, and 10 is negative plate, and 11 is dividing plate, and 12 is negative plate, and 13 is positive plate.

Adjustable valve-control sealed non-maintaining cylindrical excide battery comprises shell 1, places positive plate 13 and the pole 7-1 and the lead-in wire 7-2 of shell 1 the inside.Negative plate 10 and pole 7-3 thereof and lead-in wire 7-4, positive and negative electrode panel area band one dividing plate 11, sealed cell lid 2, brace 9 is loaded on the negative plate 12 and the positive electrode cap above the battery cover 3 of battery bottom, adopt at the extension of positive and negative terminals 7-1, the 7-3 of battery and long to solidify sealing on a large scale apart from polyamide, establish a cone valve 6 in the battery cover steam vent, the valve point is put an elastic caoutchouc post 5 downwards above the cone valve 6, by adjustment screw 4, change the pressure that elastic caoutchouc post 5 gives cone valve 6.Before the assembling, earlier separately that battery cover 2 peripheries are airtight good, feed compressed air from steam vent A, adjust adjustment screw 4 simultaneously, according to the air gauge indicated value, be transferred to and make it drive valve and close valve pressure atmospheric pressure value up to specification; During the battery assembling, only need load onto the battery cover of adjusting, the embedding polyamide is sealed, and injects electrolyte, need not to adjust again, just can satisfy the requirement of battery operate as normal.
