【発明の詳細な説明】 産業上の利用分野 本発明は、蓄電池の排気部の構造の改良に関するもの
である。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in the structure of an exhaust portion of a storage battery.
従来技術とその問題点 従来、密閉形鉛蓄電池等に用いられている排気部の構
造は、筒状の排気口にキャップ状のゴム弁を装着し、該
ゴム弁が該排気口から離脱しないように、該ゴム弁の頭
部から平板状の押え板で押えて保持する構造であった。Conventional technology and its problems Conventionally, the structure of an exhaust portion used in a sealed lead-acid battery or the like has a cap-shaped rubber valve attached to a cylindrical exhaust port so that the rubber valve does not detach from the exhaust port. Further, the rubber valve has a structure in which the head is pressed and held by a flat pressing plate from the head of the rubber valve.
しかし、上記構造ではキャップ状ゴム弁を正規の位置
に装着することが困難であるという欠点があった。特に
電解液を注入後に該ゴム弁を排気口に装着すると、注液
直後から極板活物質と電解液とが反応してCO2ガスが発
生するため、該ゴム弁を押え板で押えるまでにCO2ガス
により該ゴム弁が微動し、正規でない位置、即ち電池内
部と外部とが開放された状態で前記押え板で保持される
という欠点があった。また、CO2の発生しなくなるまで
待って該ゴム弁を装着すると、電池を単に放置しておく
だけのストック工程が必要となり、生産性が低くなると
いう欠点があった。However, the above structure has a drawback that it is difficult to mount the cap-shaped rubber valve at a regular position. In particular, when the rubber valve is attached to the exhaust port after injecting the electrolytic solution, the electrode plate active material and the electrolytic solution react immediately after the injection to generate CO 2 gas. There was a drawback that the rubber valve was slightly moved by CO 2 gas, and was held by the holding plate in an irregular position, that is, in a state where the inside and outside of the battery were opened. Further, if the rubber valve is mounted after waiting until CO 2 is no longer generated, there is a disadvantage that a stock process of simply leaving the battery unnecessary is required, and the productivity is reduced.
発明の目的 本発明は上記欠点を解消したもので、電解液を注入し
て極板活物質と反応してCO2ガスが発生中であっても、
すぐに排気弁を正規位置に装着できる信頼性の高い品質
で、且つ生産性を向上することができる排気弁と排気弁
を位置保持する構造を有する蓄電池を提供するものであ
