産業上の利用分野
本発明は鉛蓄電池の安全弁装置に関し、更に詳
細には防爆フイルターを備えた鉛蓄電池の安全弁
装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a safety valve device for a lead-acid battery, and more particularly to a safety valve device for a lead-acid battery equipped with an explosion-proof filter.
従来技術の問題点
鉛蓄電池は内部から水素ガス並びに酸素ガスが
発生するため、引火爆発の危険性がある。従つ
て、これを防止する目的から防爆フイルターを装
着したものが数多く製造され、販売されている。Problems with conventional technology Lead-acid batteries generate hydrogen gas and oxygen gas from inside, so there is a risk of ignition and explosion. Therefore, in order to prevent this, many products equipped with explosion-proof filters have been manufactured and sold.
しかし、フイルターの通気抵抗のバラツキによ
り当初から通気抵抗の高いものがあつたり、蓄電

共にフイルターに導びかれて、これが次第にフイ

たりして、一部のものにフイルター詰まりによる
電槽破裂が発生した。これは、鉛蓄電池の電解液
が希硫酸であるため、希硫酸の流出により周囲と
器物を腐食させるので致命欠陥となつていた。 However, due to variations in the airflow resistance of the filters, some filters may have high airflow resistance from the beginning, and fine foreign matter such as active material powder may be guided from inside the storage battery to the filter along with the gas, and this may gradually accumulate inside the filter. , the former and the latter overlapped, and in some cases, the battery case burst due to filter clogging. This was a fatal flaw because the electrolyte in lead-acid batteries is dilute sulfuric acid, and the leakage of dilute sulfuric acid corrodes the surrounding area and equipment.
これを防止するため、従来から安全弁を他の位

爆式蓄電池として使用するものについては安全弁
を施すことが出来ない等の欠点があつた。 In order to prevent this, a method of separately providing a safety valve at another position has been proposed, but this method is unreasonable in terms of construction and area, and also leads to high costs. Additionally, batteries of general specifications (not explosion-proof) that are used as explosion-proof batteries by attaching a liquid port plug with an explosion-proof filter have drawbacks such as the inability to provide a safety valve.
発明の目的
本発明は上記従来の欠点を全て排除するもの

る。Purpose of the Invention The present invention eliminates all of the above-mentioned drawbacks of the conventional technology by configuring an explosion-proof filter and a safety valve in one place, and also makes a general specification storage battery explosion-proof and equipped with a safety valve. The present invention provides a safety valve device for a lead-acid battery that can be used as a lead-acid battery.

する。 7 is an explosion-proof filter, which is formed by adding a binder to crushed corundum powder of about 60 mesh and sintering it.
Designed to be 6mm thick. The outer shape of the explosion-proof filter 7 is almost the same as the outer shape of the sleeve 4, and the explosion-proof filter 7 is mounted in contact with the upper surface of the sleeve 4. Reference numeral 8 denotes an elastic covering, which is made of elastic and acid-resistant material such as chloroprene rubber (hardness of about 40°).
This elastic covering 8 has an opening 9 and a skirt portion 1
0 reaches below the bottom of the slit 6.
The inner diameter of the skirt portion 10 is formed smaller than the outer diameter of the sleeve 4, and when it is installed, it is pushed out and installed.

いて、小隙１４から外部へ逃げる。 Next, to explain this operation, when the explosion-proof filter 7 is conductive, the exhaust gas passes through the explosion-proof filter 7 from the opening 5, passes through 12 slits, as shown by the arrow in FIG. The exhaust gas is discharged to the outside through the small gap 14, but when the explosion-proof filter 7 is closed, the exhaust gas is discharged through the opening 5 as shown in FIG.
From there, it passes through the slit 6, pushes open the skirt portion 10, and escapes from the small gap 14 to the outside.

At Kg/cm 2 , some batteries were destroyed. Therefore,
It is appropriate to set it to 0.1-0.4Kg/ cm2 .
