Description
本発明は制御弁式鉛蓄電池に関するものである。 The present invention relates to a control valve type lead acid battery.
一般に制御弁式鉛蓄電池の弁構造は、通常時には外気が蓄電池内に流入することを防止するために閉弁し、電解液中の水の電気分解によるガス発生等によって蓄電池内圧が上昇した時には開弁することが必要である。 In general, the valve structure of a control valve type lead-acid battery is normally closed to prevent outside air from flowing into the battery, and is opened when the internal pressure of the battery rises due to gas generation due to electrolysis of water in the electrolyte. It is necessary to speak.
特許文献１には、従来のモノブロック電槽を用いた制御弁式鉛蓄電池に使用される弁構造が示されている。電槽の開口部を閉塞する蓋に注液口を兼ねた排気口を設け、その排気口の開口部周辺の弁装着部に排気口を覆うゴム板を装着する。ゴム板の上面には弾性を有する平板状のスポンジ状ゴム体を設け、前記ゴム板の上面にはゴム板を圧縮させながら上蓋が蓋と溶着等により装着されている。 Patent Document 1 discloses a valve structure used in a control valve type lead-acid battery using a conventional monoblock battery case. An exhaust port that also serves as a liquid injection port is provided in a lid that closes the opening of the battery case, and a rubber plate that covers the exhaust port is mounted on a valve mounting part around the opening of the exhaust port. A flat sponge-like rubber body having elasticity is provided on the upper surface of the rubber plate, and an upper lid is attached to the upper surface of the rubber plate by welding or the like while compressing the rubber plate.
このような構造により、セルで発生したガスによって蓄電池内圧が上昇した時は、ガスが排気口を通りゴム板を押し上げて開弁して排気溝より外部へ放出される。また、ガスを放出して内圧が低下した後は、スポンジ状ゴム体の弾性によりゴム板が閉弁して排気口が閉塞される。負極板の酸素ガス吸収反応によって電池内が減圧状態になった場合、ゴム板が大気圧により排気口に押し当てられて、外気の電池内への流入を防止する。このようにゴム板が制御弁としての役割を果たす。 With this structure, when the internal pressure of the storage battery rises due to the gas generated in the cell, the gas passes through the exhaust port, pushes up the rubber plate, opens the valve, and is discharged to the outside through the exhaust groove. Further, after the gas is released and the internal pressure is lowered, the rubber plate is closed by the elasticity of the sponge rubber body, and the exhaust port is closed. When the inside of the battery is depressurized by the oxygen gas absorption reaction of the negative electrode plate, the rubber plate is pressed against the exhaust port by atmospheric pressure to prevent the outside air from flowing into the battery. Thus, the rubber plate serves as a control valve.
特許文献１の第１図に示されたように排気口が蓋に一体に有する構造を採用した場合、蓄電池に電解液を注液する時に電解液がゴム板載置部に付着してしまう。この状態でゴム板を装着すると、弁載置部とゴム板の接触面には硫酸分が残留してしまう。この状態で蓄電池を長期間使用すると硫酸により弁載置部表面とゴム弁板が変質し、両者が貼り付いてしまう。これによりゴム板の開弁圧が上昇し、結果として電槽が変形するという問題が生じていた。 As shown in FIG. 1 of Patent Document 1, when the structure in which the exhaust port is integrally provided with the lid is adopted, the electrolyte solution adheres to the rubber plate mounting portion when the electrolyte solution is injected into the storage battery. If the rubber plate is attached in this state, sulfuric acid remains on the contact surface between the valve mounting portion and the rubber plate. If the storage battery is used for a long period of time in this state, the surface of the valve mounting portion and the rubber valve plate are denatured by sulfuric acid, and both are adhered. As a result, the valve opening pressure of the rubber plate is increased, resulting in a problem that the battery case is deformed.
特許文献２には、鉛蓄電池の電槽化成方法が示されており、鉛蓄電池に電解液比重が１．１８０以下の希硫酸を注液して電槽化成を効率良く行い、電槽化成終了後に蓄電池を反転し脱液した後、比重１．４００以下の希硫酸を注入して再充電することで電解液が攪拌され、適正な電解液濃度にする方法が示されている。 Patent Document 2 discloses a method for forming a battery case for a lead-acid battery, in which a dilute sulfuric acid having an electrolyte specific gravity of 1.180 or less is injected into the lead-acid battery to efficiently perform the battery case formation, and the battery case formation is completed. A method is shown in which the storage battery is inverted and drained, and then diluted sulfuric acid having a specific gravity of 1.400 or less is injected and recharged to agitate the electrolyte to obtain an appropriate electrolyte concentration.
この電槽化成方法を採用しようとした場合、蓄電池を反転し脱液する際に電解液が弁載置部に残留し、ゴム板が弁載置部に固着してしまうという問題があった。 When this battery case forming method is to be adopted, there is a problem in that when the storage battery is reversed and drained, the electrolytic solution remains on the valve mounting portion, and the rubber plate adheres to the valve mounting portion.
さらに、特許文献１に示されたゴム板を用いた弁構造は、弁の信頼性を得るために注液及び排気口の内径が小さくなるため、特許文献２に示した電槽化成を行う場合、蓄電池への電解液の注液及び脱液に時間を要すという問題も生じていた。 Furthermore, in the valve structure using the rubber plate shown in Patent Document 1, since the inner diameter of the liquid injection and the exhaust port becomes small in order to obtain the reliability of the valve, the battery case formation shown in Patent Document 2 is performed. In addition, there has been a problem that it takes time to inject and remove the electrolyte from the storage battery.
特許文献３には、前述の課題に対し、図１に示されたように電槽の開口部を閉塞する蓋に設けた注液口に、装着されるように制御弁（安全弁）部を有する液栓を備え、前記制御部の弁体周囲から電槽方向に突出する筒部を備えた制御弁式鉛蓄電池が示されている。 Patent Document 3 has a control valve (safety valve) part to be attached to a liquid injection port provided in a lid that closes the opening part of the battery case as shown in FIG. There is shown a control valve type lead-acid battery that includes a liquid stopper and includes a cylindrical portion that protrudes from the periphery of the valve body of the control portion toward the battery case.
しかしながら、制御弁を構成するに当たり、液栓にはそれぞれゴム板、発泡ゴム体、上蓋が必要となり、各セルに対応する個々の液栓が必要であり、部品点数の増加およびそれに伴う液栓装着工数が増加するという課題があった。
本発明は、複数セルを有したモノブロック電槽を用い、蓋には注液兼脱液口を有した構造を有した構成を有した制御弁式鉛蓄電池において、電槽化成の注液及び脱液を容易にし、部品点数の削減によるコスト及び工数低減を図るのを目的とする。 The present invention uses a monoblock battery case having a plurality of cells, and in a control valve type lead storage battery having a structure having a liquid injection / drain port on the lid, The purpose is to facilitate drainage and to reduce costs and man-hours by reducing the number of parts.
上記の課題を解決するために、本発明の請求項１記載に係る発明は、一方向に隣接する複数セルを有したモノブロック電槽の開口部を閉塞する蓋の上面には、凹部を一方向に連続的に設けるとともに凹部の底部には各セルに対応する注液兼脱液口を備え、注液兼脱液口には上下に開口した着脱可能な液口体を装着し、複数の前記液口体の上面には一枚の平板状ゴム弁を配置し、蓋と一体化した上蓋によりクッション材を介し平板状ゴム弁を押圧する制御弁式鉛蓄電池を示すものである。 In order to solve the above-mentioned problem, the invention according to claim 1 of the present invention has a recess on the upper surface of the lid that closes the opening of the monoblock battery case having a plurality of cells adjacent in one direction. In addition, the bottom of the recess is provided with a liquid injection / discharge port corresponding to each cell, and the liquid injection / discharge port is equipped with a detachable liquid port body that is opened up and down, The control valve type lead acid battery which arrange | positions one flat rubber valve on the upper surface of the said liquid mouth body, and presses a flat rubber valve via a cushion material with the upper cover integrated with the cover is shown.
さらに、本発明の請求項２に係る発明は、蓋と上蓋が一体化された状態において、蓋の上面が実質的に平面である制御弁式鉛蓄電池を示すものである。 Furthermore, the invention according to claim 2 of the present invention shows a control valve type lead-acid battery in which the upper surface of the lid is substantially flat when the lid and the upper lid are integrated.
本発明の制御弁式鉛蓄電池は、上記構成を有し、蓋の凹部に大きな注液兼脱液口を設けることで電槽化成時の注液及び脱液に要する時間を削減できるとともに、一枚の平板状ゴム弁で複数の液口体に対応することができるため、部品点数の削減によるコスト及び工数低減が図れるという効果を有し、工業上、極めて有用である。 The control valve type lead-acid battery according to the present invention has the above-described configuration, and by providing a large liquid injection / drain port in the concave portion of the lid, it is possible to reduce the time required for liquid injection and liquid discharge during battery case formation. Since a single flat rubber valve can cope with a plurality of liquid orifices, it has the effect of reducing costs and man-hours by reducing the number of parts, and is extremely useful industrially.
以下、本発明の実施の形態を、図面を参照しまがら説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図１は、本発明による制御弁式鉛蓄電池の構成説明図である。 FIG. 1 is a configuration explanatory view of a control valve type lead storage battery according to the present invention.
モノブロック電槽１は、隔壁２により仕切られたセル３が複数により構成され、矢印で示した隣接するセル方向へセルが順次形成されたモノブロック電槽１に、極板群（図示はしていない）が挿入されて隔壁２を介して隣接セルへ接続される。モノブロック電槽１の上部には、一枚の蓋４が接着又は溶着によりモノブロック電槽１へ一体化され、蓋４の上部には電池外部への接続のための正極端子５と負極端子６が設けられている。前記蓋４の上面には、セル３の接続方向へ凹部７を連続的に設け、凹部７の底部には各セルに対応するように注液兼脱液口８を有する。 The monoblock battery case 1 is composed of a plurality of cells 3 partitioned by a partition wall 2, and the monoblock battery case 1 in which cells are sequentially formed in the direction of adjacent cells indicated by arrows, Is not inserted) and connected to the adjacent cell through the partition wall 2. A single lid 4 is integrated into the monoblock battery case 1 by bonding or welding at the upper part of the monoblock battery case 1, and a positive terminal 5 and a negative terminal for connection to the outside of the battery are provided at the upper part of the cover 4. 6 is provided. Concave portions 7 are continuously provided on the top surface of the lid 4 in the connecting direction of the cells 3, and a liquid injection / drain port 8 is provided at the bottom of the concave portion 7 so as to correspond to each cell.
注液兼脱液口８より、密度が約１．１８の希硫酸電解液を注液し、通電することにより電槽化成を行う。電槽化成終了後に電池を反転して注液兼脱液口８より電解液を排出し、密度約１．４００の電解液を再度注液し、当初の通電電流より大きな電流にて通電することで、電解液から盛んにガス発生することにより電解液が攪拌され、所定の電解液濃度を得ることができる。 A dilute sulfuric acid electrolyte having a density of about 1.18 is injected from the injection / drainage port 8 and energized to form a battery case. After the formation of the battery case, the battery is inverted and the electrolytic solution is discharged from the pouring and draining port 8, and the electrolytic solution having a density of about 1.400 is poured again and energized at a current larger than the initial energizing current. Thus, by vigorously generating gas from the electrolytic solution, the electrolytic solution is stirred, and a predetermined electrolytic solution concentration can be obtained.
注液兼脱液口８には、上面が平面状な液口体９が前記注液兼脱液口８に装着され、それぞれの液口体９の上面９ａには、一枚の平板状ゴム弁１０（平面状のゴム板）を配置し、前記平板状ゴム弁１０の上にはクッション材１１を載置して、さらに上蓋１２を蓋４に溶着することで、前記クッション材１１を介して前記平板状ゴム弁１０を押圧する。 A liquid port body 9 having a flat upper surface is attached to the liquid injection / drain port 8 and the upper surface 9a of each liquid port body 9 has a flat rubber plate. A valve 10 (a flat rubber plate) is disposed, a cushion material 11 is placed on the flat rubber valve 10, and an upper lid 12 is welded to the lid 4, so that the cushion material 11 is interposed therebetween. Then, the flat rubber valve 10 is pressed.
図２は、本発明による各セルの注液兼脱液口の構造説明図である。 FIG. 2 is an explanatory view of the structure of the liquid injection / drainage port of each cell according to the present invention.
蓋４の上面に設けられた凹部７内に存在する注液兼脱液口８のセル３への注液兼脱液口の開口部８ａは、直径１５ｍｍ以上を有するのが望ましい。この注液兼脱液口の開口部８ａの直径を小さくすると、注液及び脱液の際、特に脱液の工程において、電解液が注液兼脱液口の開口部８ａにおいて表面張力の影響によりセル内の電解液と大気とが置換されないことがある。注液兼脱液口８は注液兼脱液口のねじ部８ｂを有し、その部分に上下に開口する筒を有した液口体９のねじ部９ｂが装着されることで、液口体のねじ部９ｂの上の周縁に配したゴムパッキン１３により液口体９の外側と注液兼脱液口８との気密が保たれる。 It is desirable that the opening 8a of the liquid injection / drainage port into the cell 3 of the liquid injection / drainage port 8 present in the recess 7 provided on the upper surface of the lid 4 has a diameter of 15 mm or more. If the diameter of the opening 8a of the liquid injection / drainage port is reduced, the influence of the surface tension on the opening 8a of the liquid injection / drainage port during the liquid injection and liquid removal, particularly in the step of liquid removal. As a result, the electrolytic solution in the cell and the atmosphere may not be replaced. The liquid injection / discharge port 8 has a screw portion 8b of the liquid injection / discharge port, and the screw portion 9b of the liquid port body 9 having a cylinder opening up and down is attached to the liquid injection / discharge port. The rubber packing 13 disposed on the peripheral edge on the threaded portion 9b of the body maintains the airtightness between the outside of the liquid mouth body 9 and the liquid injection / discharge port 8.
液口体の上面９ａは、制御弁として機能する平板状ゴム弁１０と直接接触するため平面にする必要があり、接触面積を広く取る方が良い。具体的には、液口体９の上下に開口する筒９ｃの内径が７ｍｍで液口体の上面９ａの直径を２０ｍｍとした場合、平板状ゴム弁１０の幅は同じ２０ｍｍとする。液口体９の直径と平板状ゴム弁１０の幅を同じにするのは、平板状ゴム弁の安定した開弁圧力及び閉弁圧力を得るため、平板状ゴム弁１０による凹部７や蓋４との接触を避けるためである。 The upper surface 9a of the liquid mouth body needs to be flat because it is in direct contact with the flat rubber valve 10 functioning as a control valve, and it is better to take a wide contact area. Specifically, when the inner diameter of the cylinder 9c opened up and down the liquid mouth body 9 is 7 mm and the diameter of the upper surface 9a of the liquid mouth body is 20 mm, the width of the flat rubber valve 10 is the same 20 mm. In order to obtain a stable valve opening pressure and valve closing pressure of the flat rubber valve, the diameter of the liquid body 9 and the width of the flat rubber valve 10 are the same. This is to avoid contact with.
平板状ゴム弁１０は、厚み１ｍｍで液口体９の直径とほぼ同じ幅のクロロプレン製ゴムで、ＪＩＳスプリング式硬さ試験機ＪＩＳのＡ形を用いて硬度は約６０°相当を用い、液口体の上面９ａと平板状ゴム弁１０との間にはシリコンオイル等を存在させることにより制御弁としての気密性が保たれる。平板状ゴム弁１０の上に配置されるクッション材１１は、ＥＰＤＭによる連続気泡体により平板状ゴム弁と同寸法として用いる。上蓋１２は、蓋４と同材質を用い溶着等により部分的に間隙（図示はしていない）を設け、蓋と一体化することで、クッション材１１を介して平板状ゴム弁１０を押圧する。 The flat rubber valve 10 is a chloroprene rubber having a thickness of 1 mm and a width substantially the same as the diameter of the liquid mouthpiece 9, using a JIS spring type hardness tester JIS A type with a hardness equivalent to about 60 °. By allowing silicon oil or the like to exist between the upper surface 9a of the mouth body and the flat rubber valve 10, airtightness as a control valve is maintained. The cushion material 11 arranged on the flat rubber valve 10 is used as the same size as the flat rubber valve by the open cell body by EPDM. The upper lid 12 is made of the same material as the lid 4 and is partially provided with a gap (not shown) by welding or the like, and is integrated with the lid to press the flat rubber valve 10 via the cushion material 11. .
セル３内でガスが発生し、セルの内圧が上昇した場合、発生ガスは、液口体の筒９ｃより押圧している平板状ゴム弁１０を押し上げて上蓋１２の間隙より大気中に放出され、内圧が低下すると平板状ゴム弁は液口体の上面９ａを閉塞する。充電時以外は、平板状ゴム弁１０は閉弁状態で、充電により生じたセル内の酸素ガスが負極板に吸収され、セル内は減圧状態になり、大気中からの酸素のセル内への進入を防止できる。 When gas is generated in the cell 3 and the internal pressure of the cell rises, the generated gas is released from the gap between the top lid 12 into the atmosphere by pushing up the flat rubber valve 10 pressed from the cylinder 9c of the liquid mouth. When the internal pressure decreases, the flat rubber valve closes the upper surface 9a of the liquid mouthpiece. Except at the time of charging, the flat rubber valve 10 is in a closed state, oxygen gas in the cell generated by charging is absorbed by the negative electrode plate, the inside of the cell is decompressed, and oxygen from the atmosphere enters the cell Prevent entry.
上記のように構成することで、複数セルを有したモノブロック電槽に、蓋には広い径を有した注液兼脱液口を形成することができるため電槽化成の注液及び脱液を容易にすることができ、部品点数の削減によるコスト及び工数低減が図れる。 By configuring as described above, the monoblock battery case having a plurality of cells can be formed with a liquid injection / discharge port having a wide diameter on the lid, so that the injection and discharge of the battery case chemicals The cost and man-hours can be reduced by reducing the number of parts.
本発明は、電槽化成時の注液及び脱液の時間を短縮することができるとともに、一枚の平板状ゴム弁で複数のセルに対応できる制御弁式鉛蓄電池が得られるので、その工業的価値は高い。 The present invention can reduce the time for injecting and draining during the formation of the battery case, and a control valve type lead-acid battery that can handle a plurality of cells with a single flat rubber valve. Target value is high.
