Abstract
The present invention relates to a method used for separating and eliminating the defects and unreliability which exist in a mixed type device which can be used as a through hole of an exhaust valve and a liquid feeding hole, and the mixed type device is generally adopted by the prior art of a lead accumulator. The through hole of the exhaust valve and a liquid feeding and sealing device are respectively independent, and a rubber lantern ring is adopted to tighten an exhaust through hole which is arranged on the traverse side of an exhaust valve column to increase the sealing reliability of a one-way exhaust valve and reduce the air leak probability. A liquid feeding hole sealing device is independently designed, a thread rotating and blocking device which is inlaid with a rubber plug is adopted to seal the liquid feeding hole, lead accumulators are generally mixed into a whole, and the present invention respectively and independently solves the defects of air exhaust and liquid feeding sealed technology, which are not easy to be solved at the same time.
Description
The present invention relates to the electrochemical power source field of batteries.
Prior art is to the sealing mode of the exhaust hole and the liquid feeding closed hole of sealed lead accumulator vent valve, all adopt " female cap hat type " or " sheet rubber is pressed stifled formula " sealing mode, and still there is defective in the sealing airtight performance of this class mode, this class sealed cell of the shared large through-hole of steam vent and liquid filling hole particularly, the probability of its gas leakage dehydration is higher, the rubber parts of former because shutoff exhaust hole and the limit, exhaust hole aperture that is closed receive that to touch loop wire long, excessive with acid solution acid mist contact area, exhaust hole 360 degree garden ring wall faces, belong to the garden week contact sealing area that several contact points assemble, some loose contacts of Shang Ruoyin or rubber parts corrosion resistant performance reduce, or elasticity is weathering, easily cause sealing property to reduce, the storage battery gas dehydration of overflowing.
The objective of the invention is to change the deficiencies in the prior art part, the liquid filling hole double as vent valve through hole redesign of before heavy caliber area is independent structures separately.With the pin exhaust structure of vent design in the horizontal side end face of top closure formula vent valve hollow pillar, and using " O " shape rubber lock ring collar with this exhaust hole lock ring sealing, liquid filling hole adopts the screw thread that contains the stifled liquid head of cone rubber to revolve to block cap and seals.
Technical scheme of the present invention:
" sealed lead accumulator rubber hooped type one-way exhaust valve and liquid feeding sealing device " revolved by top closure formula vent valve hollow pillar 1, the O shape rubber lock ring collar 2, horizontal side exhaust hole 3, exhaust polyrrhea groove 4, liquid feeding closed hole 5, the close liquid for plugging head 6 of cone rubber, plastic whorl hollow and blocks cap 7 and formed.
The structure of rubber hooped type one-way exhaust valve is: a horizontal side exhaust hole 3 is laterally opened through exhaust polyrrhea groove 4 in the horizontal side end face of top closure formula vent valve hollow pillar 1, with the O shape rubber lock ring collar 2 cuffs on top closure formula vent valve hollow pillar 1, the horizontal side exhaust hole 3 of this vent valve pillar is sealed by lock ring, electrochemical substance and gas in the cell body are completely cut off with outside atmosphere.
The structure of liquid feeding sealing device is: the plastic whorl hollow that will contain the close liquid for plugging head 6 of cone rubber revolves and blocks cap 7 and be screwed in the liquid feeding closed hole 5, the liquid feeding closed hole can be sealed.
The present invention is compared with the prior art:
1, with existing " female cap hat type " or " sheet rubber is pressed stifled formula " structure, changes one-way exhaust valve structure into, reduced the gas leakage probability, improved the air-tightness reliability of one-way exhaust valve with the horizontal side exhaust hole of O shape rubber collar lock ring.
2, existing heavy caliber exhaust hole change is designed to horizontal side exhaust pinhole aperture, the contact aperture area of rubber packing material and acid mist acid solution is dwindled greatly, also set simultaneously unique aspect (horizontal stroke is direction then) of draining gas, when gas pressure in the cell body is enhanced to the coefficient of elasticity that overcomes the rubber lock ring collar, rubber lock ring collar automatic valve opening makes the air pressure in the cell body obtain draining.
3, after independently the liquid feeding closed hole was screwed sealing, closed performance was good, gas, liquid seepage can not occur.
Description of drawings:
1---top closure formula vent valve hollow pillar; 2---the O shape rubber lock ring collar; 3---horizontal side exhaust hole; 4---the exhaust polyrrhea groove; 5---the liquid feeding closed hole; 6---the close liquid for plugging head of cone rubber; 7---the plastic whorl hollow revolves and blocks cap.
Implementation method:
1, top closure formula vent valve hollow pillar 1 and liquid feeding closed hole 5 all can be shaped by the injection moulding demoulding.
2, transverse row vent hole 3 and exhaust polyrrhea groove 4, the shaping of when the injection moulding demoulding, laterally loosing core.
3, the plastic whorl hollow revolves and blocks cap 7, is shaped by the injection moulding demoulding.
4, the O shape rubber lock ring collar 2 is shaped through the pressing mold moulding with the acid-resisting rubber raw material, and with its cuff on top closure formula vent valve hollow pillar 1, with horizontal side exhaust hole 3 sealings.
5, the close liquid for plugging head 6 of cone rubber is shaped through moulding mold pressing glue, and it is bumped into the plastic whorl hollow revolves and block in the cap 7.
6, the plastic whorl hollow that will contain the close liquid for plugging head 6 of cone rubber revolves and blocks cap 7 and be screwed in the liquid feeding closed hole 5, realizes the sealing to the liquid feeding closed hole.
By above method, realize " sealed lead accumulator rubber hooped type one-way exhaust valve and liquid feeding sealing device " this structure.
