された場合等の非常時となり、ゴム弁１の役割は
一般的には電池の破壊を防止する為にある事にな
る。 Originally, a battery performs its original function in a sealed state, and under normal use, the internal pressure can be ignored as it is less than half the operating pressure of the rubber valve 1. Therefore, the rubber valve 1 operates in emergencies such as when charging with an extremely large current causes the equilibrium internal pressure to exceed the valve pressure, or when reverse charging occurs, and the role of the rubber valve 1 is generally This is to prevent battery damage.

を及ぼす事がある。Problems to be Solved by the Invention When the rubber valve 1 is operated in an emergency like the one described above, the problem is that alkali hydroxide mist as an electrolyte may be released as the internal gas is released to the outside. be. Alkali hydroxide mist is a highly corrosive liquid that can cause damage to surrounding equipment.

8 is a separator, 9 is an anode connection terminal, 10 is a cathode connection terminal, and 11 is a packing.
問題点を解決するための手段
本考案は上記の点に鑑み、弁体外周部の内側に
凹部が形成されて最外周のゴム部分の高さを上蓋
の弁体収納部分の内側の高さに等しくなし、弁体
凸部高さは最外周のゴム部分の高さより高くした
弁体を安全弁素子として使用するものである。Means for Solving the Problems In view of the above points, the present invention has a recess formed inside the outer circumference of the valve body so that the height of the outermost rubber part is equal to the height of the inside of the valve body housing part of the top cover. The height of the convex portion of the valve body is higher than the height of the outermost rubber portion, and the valve body is used as a safety valve element.
作 用
弁体の弁体外周部の端部が、上蓋に密接してい
るので、外部にミストが洩れることを防止する。Function Since the end of the outer periphery of the valve body is in close contact with the top cover, mist is prevented from leaking to the outside.
実施例
軟質ゴム等からなる弁体１２は最外周のゴム部
分の高さＨ寸法が、陽極端子蓋４の弁体収納部分
の内側の高さに等しく、又中央部の弁体凸部１３
の高さＨ＋ｈが、上記最外周のゴム部分の高さよ
りｈ寸法だけ高い構造をもつ弁体１２を安全弁素
子として使用し、上蓋２と陽極端子蓋４の間に収
納する。Embodiment The height H of the outermost rubber portion of the valve body 12 made of soft rubber or the like is equal to the height of the inside of the valve body storage portion of the anode terminal cover 4, and the valve body convex portion 13 at the center
A valve body 12 having a structure in which the height H+h is higher than the height of the outermost rubber portion by the dimension h is used as a safety valve element and is housed between the upper cover 2 and the anode terminal cover 4.
この様にすることにより、万一弁体１２が収縮
して水酸化アルカリミストが放出されても、弁外
周部１４の端部が上蓋２に密接しているので、外
部にミストが洩れる事が防止される。なお、何回
も弁体１２が作動してミストが放出された場合に
は、ここでのトラツプは充分とは言えなくなる
が、前記した様に弁体１２が作動するのは一般的
に極端な条件にて使用される非常時にかぎられて
おり、通常での使用では未作動であるから、上記
内容にて機能は満足する。 By doing this, even if the valve body 12 contracts and alkali hydroxide mist is released, the end of the valve outer circumference 14 is in close contact with the upper lid 2, so the mist will not leak to the outside. Prevented. Note that if the valve element 12 is activated many times and mist is released, the trap here will not be sufficient, but as mentioned above, the activation of the valve element 12 is generally an extreme case. Since it is used only in emergencies under certain conditions and is not activated during normal use, the above content is sufficient for the function.
なお、１５は弁体外周部１４の内側に有するリ
ング状の凹部である。 Note that 15 is a ring-shaped recess formed inside the outer peripheral portion 14 of the valve body.
次に、適正電解液の30％増加量をKR−Ｃ形ア
ルカリ蓄電池に注入した逆光電を行なつた結果で
は、１回の弁体作動にて従来のゴム弁１が30％の
ミストの洩れが認められたのに対して、本考案に
よる弁体１２はミストの洩れは５％であつた。 Next, the results of back photovoltage injecting a 30% increase in the amount of appropriate electrolyte into a KR-C type alkaline storage battery showed that the conventional rubber valve 1 leaked 30% of the mist with one valve actuation. On the other hand, the mist leakage of the valve body 12 according to the present invention was 5%.
