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 usage conditions, the operating pressure of the internal pressure rubber valve 1 may be less than half. 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.The role of the rubber valve 1 is generally that of the battery. It is there to prevent destruction.

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
本考案は上記の如き点に鑑み、弁体外周部の内
側にリング状の凹部をもつと共に最外周のゴム部
分の高さを上蓋の弁体収納部分の内側の高さより
高くして、弁体凸部の高さは上記最外周のゴム部
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 ring-shaped recess inside the outer periphery of the valve body, and the height of the outermost rubber part is set to the inside of the valve body housing part of the upper cover. The height of the valve body convex portion 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、上蓋に加圧して密
接しているので、外部にミストが出るのを防止す
る。Function: The edge of the outer circumference of the valve body is pressurized and in close contact with the top cover, which prevents mist from coming out to the outside.
実施例
軟質ゴム等からなる弁体１２の最外周のゴム部
分の高さが、陽極端子蓋４の弁体収納部分の内側
の高さＨよりもh2だけ高く、又中央部の弁体凸部
１３の高さが、弁体収納部分の内側の高さＨより
h1だけ高く（但しh1＞h2）なる様な構造をもつ弁
体１２を安全弁素子として使用し、これを陽極端
子蓋９の弁体収納部分に収納して電池蓋部分とな
す。Example The height of the outermost rubber portion of the valve body 12 made of soft rubber or the like is higher by h 2 than the height H of the inside of the valve body housing portion of the anode terminal cover 4, and the height of the valve body convex in the center is The height of part 13 is higher than the height H inside the valve body housing part.
A valve body 12 having a structure such that the height is h 1 (where h 1 >h 2 ) is used as a safety valve element, and this is housed in the valve body housing part of the anode terminal cover 9 to form a battery cover part.
安全弁体としてこれを使用した場合、弁体外周
部１４は、Ｈ寸法よりh2だけ高さ寸法が大である
ため、ある程度の安全弁体としての機能を持つ。
この場合、弁体凸部１３より弱い圧力にて外側に
広がる事になる。 When this valve body is used as a safety valve body, the valve body outer peripheral portion 14 has a height dimension larger than the H dimension by h 2 , so that it functions as a safety valve body to some extent.
In this case, the pressure will be weaker than that of the valve body convex portion 13 and it will spread outward.
この様にする事により、万一弁体１２が収縮し
てアルカリミストが放出されても、弁体外周部１
４の端部が上蓋１０に弱い圧力ではあるが加圧し
て密接しているので、外部にミストが出る事が防
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 alkaline mist is released, the outer circumference of the valve body 1
Since the end of 4 is in close contact with the upper lid 10 under slight pressure, mist is prevented from coming out to the outside. 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. The function is satisfied with the above content because it is used only in emergency situations and is not activated during normal use.
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 recessed portion provided 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充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２％であつた。 Next, the results of reverse charging by 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 mist with one valve operation. On the other hand, the mist leakage of the valve body 12 according to the present invention was 2%.
考案の効果
上述のように本考案によれば、弁体の作動が良
好であり、外部へのミストの洩れを減少ならしめ
ることができる等実用的価値甚だ大なるものであ
る。Effects of the Invention As described above, the present invention has great practical value, as the valve body operates well and the leakage of mist to the outside can be reduced.
