従来・この種密閉形鉛蓄電池は、第3図に示す通シ、鉛
蓄電池内で発生するガスを排出する一方、外部の空気を
鉛蓄電池内に入れないだめの安全弁として、キャップ形
のゴム弁が使用されていた。Conventional technology Conventionally, this type of sealed lead-acid battery has a cap-type cap as shown in Figure 3, which serves as a safety valve to exhaust the gas generated inside the lead-acid battery and prevent outside air from entering the lead-acid battery. rubber valves were used.

に内圧が上昇した場合は、キャップ形ゴム弁5の内壁か
らの圧力でゴム弁5が膨張し、気密性が開放されてガス
つ二中ふた2と上ふだ7との間から外部に排出される。In the configuration shown in the figure, 1 is a battery case, 2 is an inner lid that covers the upper opening of the battery case 1, 3 is a recess provided in the upper surface of the inner lid 2, and an exhaust port 4 is provided in the inner lid of the recess 3. was formed into a pipe shape, and its tip was hermetically closed with a cap-shaped rubber valve 5. However, in order to prevent the cap-shaped rubber valve 6 from gradually rising due to the pressure of gas generated in the battery case and eventually coming off from the pipe-shaped exhaust port 4, a slight clearance is provided above the cap-shaped rubber valve 5. The valve holding plate 6 was fixed. Therefore, even if the rubber valve 6 mentioned above rises due to internal pressure, it will not fall out and the valve holding plate will act as a stopper to hold it in place. If the internal pressure rises further, the pressure from the inner wall of the cap-shaped rubber valve 5 will cause the The valve 5 expands, the airtightness is opened, and the gas is discharged to the outside from between the inner lid 2 and the upper lid 7.
このようにガスが排出される場合は鉛蓄電池の充電時で
あるが、放電時には逆に電槽内の圧力は減圧し、前記キ
ャップ形ゴム弁5は引き下げられ、排気口4のパイプ上
端に密着し、更に減圧されればキャップ形ゴム弁5の上
面部は外気圧に押されて凹球面状にわん曲する。When gas is discharged in this way, it is during charging of the lead-acid battery, but when discharging, the pressure inside the battery container decreases, and the cap-shaped rubber valve 5 is pulled down and tightly attached to the upper end of the pipe of the exhaust port 4. However, when the pressure is further reduced, the upper surface of the cap-shaped rubber valve 5 is pushed by the external pressure and curves into a concave spherical shape.

し返され抜は落ちてしまう。そのため、このゴム弁5を
押えながら同時に弁押え板6を固定する必要があった。Problems to be Solved by the Invention The safety valve for a sealed lead-acid battery having the above configuration has two problems: the cap-shaped rubber valve 5 must be inserted into the pipe section of the exhaust port 4, and the shape is small; Since the exhaust port 4 is located at the top of each cell chamber in the tank, a large number of cap-shaped rubber valves 5 must be inserted, which requires a lot of man-hours. Furthermore, when assembling a normal lead-acid battery, the rubber valve 5 is inserted after the electrolyte is injected into the battery case through the exhaust port 4, and when the electrolyte is injected, it is replaced with the air inside. Since the exhaust port 4 is under pressure due to gas discharge or gas generation due to the reaction between the electrolyte and the electrode, the inserted cap-shaped rubber valve 5 is instantly pushed back and the cap-like valve 5 falls out. Therefore, it was necessary to hold the rubber valve 5 while simultaneously fixing the valve holding plate 6.
この例は2セルの例であるが、電圧が高い即ちセル数の
多い鉛蓄電池であれば、このキャップ状ゴム弁5を数個
同時に挿入し、前記したゴム弁5の抜は落ちを阻止しな
がら弁押え板6を固着することは非常に困難な作業であ
った。また数個のゴム弁5を固着させるためには強固な
弁押え板が必要であった。Although this example is for a 2-cell lead-acid battery, if the voltage is high, that is, the number of cells is high, several cap-shaped rubber valves 5 may be inserted at the same time to prevent the rubber valves 5 from falling out when removed. However, fixing the valve holding plate 6 was a very difficult task. In addition, a strong valve holding plate was required to secure the several rubber valves 5.
また1人の作業者でこのような組立を行なうことは不可
能であって、複数の作業者を必要とした。Furthermore, it is impossible for one worker to carry out such assembly, and a plurality of workers are required.
またコンベア上で多量に組立ている場合に、キャップ状
ゴム弁6の脱落を見逃すことなく完全に組立てるために
は、作業者の高度な注意力を必要とした。Furthermore, when assembling a large number of valves on a conveyor, a high degree of attentiveness is required by the operator in order to completely assemble the cap-shaped rubber valve 6 without missing it.
本発明はこうした繁雑な作業上の問題点を解決するため
のものである。The present invention is intended to solve these complicated operational problems.
問題点を解決するだめの手段
本発明は従来のようなキャップ状ゴム弁を排し、平面状
の弁座に排気口を1個ないし複数個形成しこれを覆うよ
うにゴム製のシート状弁を装着したものである。Means for Solving the Problems The present invention eliminates the conventional cap-shaped rubber valve and uses a sheet-shaped valve made of rubber to cover the flat valve seat with one or more exhaust ports. It is equipped with.
作用
このように複数個の排気口を1枚のゴム製シート状弁で
覆い、平面状の弁座に密着させることで、鉛蓄電池内の
気密性をもたせ、内部加圧時にはゴムシート状弁を押し

放させることができる。Function: By covering the multiple exhaust ports with a single rubber sheet valve and placing it in close contact with the flat valve seat, the interior of the lead-acid battery is airtight, and the rubber sheet valve is used when internal pressure is applied. It can be pushed up to create a small gap between the valve seat and the flat, allowing it to open.
実施例 以下本発明の実施例について説明する。Example Examples of the present invention will be described below.
1は電槽、2は電槽上部開口部を覆う中ふた、3は中ふ
た2の上面中央部に設けた凹部で、この凹部3の底面は
平面状の弁座8を形成している。1 is a battery case, 2 is an inner lid that covers the upper opening of the battery case, and 3 is a recess provided in the center of the upper surface of the inner lid 2, and the bottom surface of this recess 3 forms a planar valve seat 8.

を案内する構成である。Reference numeral 4 designates an exhaust port provided at the center of the top of each cell chamber 9 of the lead-acid battery (the partitions between the cell chambers are not shown) of the planar valve seat 8. Reference numeral 10 denotes a rubber sheet-like valve that is in close contact with the valve seat 8 and has the exhaust port 4 hermetically closed. Reference numeral 11 denotes a cushioning material that elastically and uniformly presses the valve 1o from above. This cushioning material 11 is further covered with an upper flap 7 from the upper surface, and is placed on both sides of the upper lid 7 on both sides of the recess 3 of the inner lid 2. It is welded and fixed to the step portion 12 provided. Reference numeral 13 denotes a plurality of guide ribs provided on the inner wall of the recessed portion 3. Each guide rib 13 has a tapered portion at the upper part and is opposed from both sides, and its inner side faces the outer surface of the seat valve 1o and the cushion material 11 described above. The structure is designed to guide you through these steps.
なお、弁座8とシート弁10との密着性及び排気口4へ

に塗布するとよい。In addition, in order to provide close contact between the valve seat 8 and the seat valve 10 and airtightness to the exhaust port 4, it is preferable to apply silicone oil to the upper surface of the valve seat.
発明の効果 以上のように発明によれば次のような効果が得られる。Effect of the invention As described above, according to the invention, the following effects can be obtained.
(1)各セル毎に設けた排気口にキャンプ状ゴム弁を挿
着することなく一枚のシートを乗せるだけで弁の装着が
できる。(1) The valve can be installed by simply placing a sheet on the exhaust port provided for each cell without inserting a camp-shaped rubber valve.
(2)装着したシート状弁は、シリコーンオイルを塗布

たが、これらの部品は不要となる。その結果は従来の作
業工程からは大幅な人員削減が出来、また出来上った製
品の作業ミスもなく安定した品質が得られる。(2) The attached seat-shaped valve strongly self-adsorbs to the valve seat coated with silicone oil, and even if it becomes pressurized due to gas generation from inside the battery case as described above, the seat-shaped valve will not hold. There is no chance of it peeling off from this valve seat. Therefore, normally a valve holding plate is required during the assembly process, but these parts are no longer necessary. As a result, it is possible to significantly reduce the number of personnel compared to conventional work processes, and the finished product can be of stable quality with no operational errors.
(3)また中ふだ凹部の両側内壁に設けたガイドリブで
極めて簡単にシート状弁の装着が出来ると同時に内壁に
突起があるため、排気口から発生したガスは凹部内壁と
弁とが気密的に接触しないだめガスの放出は容易になっ
ている。(3) In addition, the guide ribs provided on the inner walls on both sides of the inner flange recess make it extremely easy to install the seat valve, and at the same time, since there is a protrusion on the inner wall, the gas generated from the exhaust port is airtight between the inner wall of the recess and the valve. Do not come in contact with the gas as it is easy to release the gas.
(4)また弁座の上面にシリコーンオイルを塗布してお

リブは防止する効果もある。(4) Also, apply silicone oil to the top surface of the valve seat. This oil usually has diffusive properties, so if the inner wall of the recess is in contact with the sheet-like valve and cushion material, capillary action will occur in the gap between them. The oil rises up and wastes oil, but the guide ribs have the effect of preventing this kind of rise.
