Abstract
The safety valve includes integrative valve body with valve spool. The body through valve spool is combined with filling hole of battery electrolyte. Ribs built on upper surface of valve body prevent vacsorb state occurred between safety valve and cover board. Thus, taking off cover board will not take off safety valve also. The invented structure increases fineness rate of cells.
Description
Technical field
The present invention relates to enclosed type cell, refer in particular to a kind of safety valve structure of enclosed type cell.
Background technology
Consult Fig. 1-shown in Figure 5, traditional closed is exempted to add water battery and is included battery body 1, and battery body 1 is established lid 10, and lid 10 tops are provided with positive and negative two utmost points 11 and 12, and establish the containing groove 100 of cover plate 13 on its surface, and this containing groove 100 is invaginated type; And establish air discharge duct 101, the containing groove 100 recessed degree of depth are the thickness of cover plate 13.Establish most battery liquid hand-holes 14 again at containing groove 100 places, each hand-hole 14 periphery is established annular groove 140, this annular groove 140 can be safety valve 15 and is installed with, after being filled into each slot electrode 16 in battery liquid, after safety valve 15 is covered on hand-hole 14, again cover plate 13 reverse (inversion) is placed aforementioned containing groove 100, make the outer surface 130 of cover plate 13 be covered on the safety valve top, as Fig. 1-shown in Figure 2, and tighten with elastic tape.So, when battery begins to charge, battery liquid can with the pole plate generation chemical change in the slot electrode 16, and generation gas 17, this gas 17 can produce the bulbs of pressure in slot electrode 16, and make gas 17 with the bottom 150 of safety valve 15 slightly to extrapolation (as shown in Figure 3), make gas 17 discharge through annular groove 140 and via air discharge duct 101 in outside.At this moment, inverted cover plate 13 is because of there being tying up of elastic tape solid, so gas 17 pressure can not make inverted cover plate deviate from.
Hand-hole 14 is covered; make slot electrode 16 produce inside suction; the upper surface 151 of safety valve 15 can be inside concavity (as shown in Figure 4); the suction of these groove 152 meetings and 130 generations of cover plate outer surface such as sucker; so when the operator takes off inverted cover plate 13; often have the situation generation (as shown in Figure 4) that safety valve 15 is adsorbed in inverted cover plate outer surface; this kind situation; represent that this battery will range in the false defective product; this battery will be recharged once or more times again, causes the increase of battery manufacturing cost.
As shown in Figure 5, desired the acceptance rate in the electrolytic cell manufacture process, needed safety valve 13 on battery all to fill with hand-hole 14 and part combine, and upper surface 151 all has a groove 152, each slot electrode that can confirm this battery is full of electric charge all and is good product.Can utilize this moment the inner surface 131 of cover plate 13 to establish most ribs 132 and containing groove 100, finish processing, can make enclosed type cell with ultrasonic waves or high frequency welding mode.Its major defect is:
Because the dysplasia between safety valve causes enclosed type cell acceptance rate in manufacture process to reduce, and increases manufacturing cost and puzzlement.
The inventor long-pending design and the manufacturing experience of correlated product are for many years studied at above-mentioned shortcoming, create technical scheme of the present invention.
