る。Conventional technology In general, a sealed lead battery is a cathode gas absorption type lead battery that has a structure in which the electrode plate and separator are impregnated with electrolyte, and the cathode plate absorbs oxygen gas generated from the anode plate, and is sealed with a sealing plug. It has a unique structure.
しかし、完全密閉ではなく、充電終期や異常に
大きい充電電流が流れた場合、陰極板でのガラス
吸収反応が酸素発生に追いつかなくなり、電池の
内圧が上昇するため、電池内圧がある圧力以上に
なると密閉弁が作動して酸素ガスを電池の外部へ
放出する構造となつている。 However, if the battery is not completely sealed and an abnormally large charging current flows at the end of charging, the glass absorption reaction on the cathode plate will not be able to keep up with the oxygen generation, and the internal pressure of the battery will rise. The structure is such that a sealing valve operates to release oxygen gas to the outside of the battery.
考案が解決しようとする問題点
このような密閉弁は、電池内圧が非常に高くな
つたときや、減圧状態から加圧状態へ変化すると
き等に、密閉弁の作動圧が安定しないという欠点
を有していた。Problems that the invention aims to solve This kind of sealing valve has the drawback that the operating pressure of the sealing valve is unstable when the internal pressure of the battery becomes extremely high or when changing from a reduced pressure state to a pressurized state. had.
問題点を解決するための手段
本考案は上記の如き欠点を除去するもので、電
槽凹部に設けられた排気孔部を覆うように、逆椀

前記密閉弁を押える密閉栓を備えたことを特徴と
するものである。Means for Solving the Problems The present invention eliminates the above-mentioned drawbacks, and provides an elastic seal with an inverted bowl shape and a protrusion at the top of the center so as to cover the exhaust hole provided in the recess of the battery case. The present invention is characterized in that it includes a sealing stopper that holds the sealing valve with a top plate having a concave portion corresponding to the protruding portion.
作 用
本考案は上記の特徴を有することにより、密閉
弁が電槽凹部の側壁にずれて接触することがない
ので、密閉弁の作動圧を安定した状態に保つこと
ができ、密閉栓の信頼性を向上することができ
る。Function The present invention has the above-mentioned features, so that the sealing valve does not shift and come into contact with the side wall of the battery case recess, so the operating pressure of the sealing valve can be maintained in a stable state, and the sealing plug is reliable. can improve sexual performance.
実施例 本考案の一実施例を説明する。Example An embodiment of the present invention will be described.
１はシール鉛電池の電槽で、２は該電槽１の凹

充電電流が流れた場合、陰極板での酸素ガス吸収
能力を上回る酸素ガスが発生し、排気孔部２を覆
つている密閉弁３の作動圧以上に電池内圧が上昇
し、密閉弁３が開放して天板排気孔５より電池外
部へ酸素ガスが排気される。 1 is a battery case for a sealed lead battery; 2 is an exhaust hole provided in a concave portion of the battery case 1; 3 is a sealing valve made of rubber or the like; 4 is a sealing valve made of rubber or the like; This is the attached top plate. Reference numeral 5 denotes a top plate exhaust hole provided in the top plate 4. At the end of charging or when an abnormally large charging current flows, oxygen gas exceeding the oxygen gas absorption capacity of the cathode plate is generated, and the exhaust hole portion 2 The battery internal pressure rises above the operating pressure of the sealing valve 3 covering the battery, the sealing valve 3 opens, and oxygen gas is exhausted from the top plate exhaust hole 5 to the outside of the battery.
本考案では、密閉弁３の中央上部に突起部６を
設けるとともに、該突起部６に対応する凹部７を
有する天板４にて密閉弁３を押えることにより、

示したａの寸法を変化させることにより調整する
ことができる。 In the present invention, a protrusion 6 is provided at the upper center of the seal valve 3, and the seal valve 3 is held down by the top plate 4 having a recess 7 corresponding to the protrusion 6.
The sealing valve 3 is prevented from coming into contact with the side wall of the recess of the battery case 1, and the operating pressure of the sealing valve 3 is stabilized.The operating pressure of the sealing valve 3 is determined by the hardness of the sealing valve and the a shown in the figure. It can be adjusted by changing the dimensions of.
考案の効果 本考案により次のような効果が認められた。Effect of invention The following effects were observed with this invention.
