本実施例ではこの幅寸法は弾性部材４の直径の８０％に
なっている。The inlet 6 is formed in the cover 5, and the width of the inlet preferably reaches 70 to 90% of the diameter of the elastic member 4.
In this embodiment, this width dimension is 80% of the diameter of the elastic member 4.

０％になっている。According to the invention, in another embodiment of the valve for sealed accumulators, the cover is in the form of a yoke or yoke 7 (third.
Figure 4). The width of both inlets formed by the wall of the yoke 7 and the base 1 reaches 70 to 90% of the diameter of the elastic member 4, and in this embodiment, the inlet width is 80% of the diameter of the elastic member 4.
It is 0%.

ではない。When gas pressure is generated in the storage battery, the gas pressure is transmitted from the inside of the sealed storage battery through the vent hole 3 (Fig. 1), and the elastic member 4 (Figs. 1 and 2) is distorted by this pressure, and When the pressure reaches a certain value, the elastic member 4 yields and vents the excess gas volume. The elastic member 4 is removed from the inlet 6 of the cover 5 when the physical and mechanical properties of the elastic member 4 deteriorate or carbonate build-up occurs. The base 1 of the valve is cleaned to remove adhering carbonates and the elastic member 4 is cleaned.
to its proper location. The width of the inlet 6 is approximately less than 70% of the diameter of the member 4 in order to avoid possible damage to the surface of the elastic member 4 when the elastic member is removed from or reinstalled in the valve. and should not be greater than approximately 90%.
後者の理由としては、もしこの入口幅が部材４の直径の
９０％より大きい場合には、過剰ガスが排気する場合に
部材４をカバー５によって十分には保持できないからで
ある。The reason for the latter is that if this inlet width is greater than 90% of the diameter of the member 4, the member 4 will not be sufficiently retained by the cover 5 when excess gas is evacuated.
損傷を与えないで弾性部材４を人口６を通して再び据え
付けるためには、その部材４の直径を１０〜３０％だけ
小さくなるよう予備圧縮しておく。即ちその大きさが入
口６の幅寸法と略等しくなるようにするのである。In order to reinstall the elastic member 4 through the prosthesis 6 without causing damage, the member 4 is pre-compressed so that its diameter is reduced by 10-30%. That is, its size is made to be approximately equal to the width dimension of the entrance 6.
カバーがくびき７ （第３．第４図）の形状をした実施

備圧縮するのである。In the embodiment in which the cover is in the form of a yoke 7 (FIGS. 3 and 4), the elastic members 4 are exchanged through opposite inlets 8, 9. The respective entrances are the first. It has a width comparable to the width of the entrance 6 shown in FIG. For reinstallation, the elastic member 4 is likewise precompressed as already described.
本発明により密封型蓄電池の弁の補修が可能となり、こ
れにより弁の寿命が延びる。The present invention makes it possible to repair the valves of sealed storage batteries, thereby extending the life of the valves.
更には、本発明により密封型蓄電池それ自身を補修可能
