くぼみができずに電池内部の減圧状態の確認が不可能に
なる。However, with the miniaturization of small sealed lead-acid batteries, the space for safety valves, etc. has also become smaller, and in conventional cap-type rubber valves with a constant wall thickness, the wall thickness of the top surface becomes relatively thick,
It is impossible to check the depressurized state inside the battery without forming a dent.
そこで電池が正常か否かの確認方法として、気密検査や
エージング後の容量検査等を実施して確認を行っていた
ため工数がかかり、コストが高くなっている。Therefore, as a method for confirming whether or not the battery is normal, airtightness inspection, capacity inspection after aging, and the like are performed for confirmation, which requires a lot of man-hours and cost.
本考案の目的は従来の欠点を解決し、小形化された小形
シール鉛蓄電池においても、キャップ型ゴム弁により内
部の減圧状態を確認し、安全性が高くしかもコストの安
い小形シール鉛蓄電池を供給しようとするものである。The object of the present invention is to solve the drawbacks of the prior art, and to provide a small sealed lead acid battery with high safety and low cost by checking the internal depressurized state with a cap-type rubber valve even for a miniaturized small sealed lead acid battery. Is what you are trying to do.
課題を解決するための手段 本考案の安全弁はキャップ型ゴム弁の側面肉厚を開弁圧
・閉弁圧が0.1〜0.3Kg/cm2の範囲に入るように設定し、
さらに天面の肉厚を減圧状態時にくぼみができるように
側面よりも薄く設定したものである。In the safety valve of the present invention, the side wall thickness of the cap-type rubber valve is set so that the opening / closing pressure is within the range of 0.1 to 0.3 Kg / cm 2 .
Further, the thickness of the top surface is set to be thinner than the side surface so that a hollow can be formed when the pressure is reduced.
作用 前記内容のキャップ型ゴム弁を小形シール鉛蓄電池に採
用することにより、安全性が高くしかもコストの安い小
形シール鉛蓄電池を供給することができる。By adopting the cap-type rubber valve having the above contents in a small sealed lead acid battery, it is possible to supply a small sealed lead acid battery with high safety and low cost.
