産業上の利用分野
本考案は、蓄電池の排気弁に関するものであ
る。[Detailed Description of the Invention] Industrial Application Field The present invention relates to an exhaust valve for a storage battery.
従来の技術
電池の内圧が異常に上昇したときのみ電池内部
から外部へ排気し、電池内部が減圧したときは外
気を吸い込まない構造の弁体は、これまでに数多
く提案されている。PRIOR ART Many valve bodies have been proposed so far that allow exhaust air from inside the battery to the outside only when the internal pressure of the battery rises abnormally, and do not suck in outside air when the pressure inside the battery decreases.
従来排気弁部の例としては第１図に示す通り、
ゴム製の逆皿状弁体１を電池内に落し込んで設け
た台座２の排気開孔部３を覆うようにカバー４で
押しつけたものであり、弁体１と台座２との接触
は線接触に近い方法による密閉構造がとられてい
る。 As shown in Fig. 1, an example of a conventional exhaust valve part is as follows.
A rubber inverted dish-shaped valve body 1 is pushed into the battery and pressed with a cover 4 to cover the exhaust hole 3 of a pedestal 2, and the contact between the valve body 1 and the pedestal 2 is linear. The structure is sealed using a method that is close to contact.
一方面接触で密封する方法としては、第２図
Ａ，Ｂに示す通りの逆カツプ状ゴム弁体１と、バ
ンド状ゴム弁体１ａを用いた２通りの方法があ
る。 There are two methods for sealing with one-sided contact: one using an inverted cup-shaped rubber valve body 1 as shown in FIGS. 2A and 2B, and the other using a band-shaped rubber valve body 1a.
考案が解決しようとする課題
しかし、従来の第１図の構成では、カバー４の
押しつけ状態により、弁動作圧力を変えられる利
点があるものの線接触であるため、電池内部減圧
時の逆止が確実に行えない問題があつた。Problems to be solved by the invention However, although the conventional configuration shown in Fig. 1 has the advantage of being able to change the valve operating pressure depending on the pressed state of the cover 4, it is a line contact, so it is not possible to ensure a check when the pressure inside the battery is reduced. There was a problem that prevented me from doing so.
また、第２図、第３図の構成では、弁体部の形
状を決めてしまうと弁動作圧力を調整する事が不
可能でありまた形状が複雑であつた。 Furthermore, in the configurations shown in FIGS. 2 and 3, once the shape of the valve body is determined, it is impossible to adjust the valve operating pressure, and the shape is complicated.
本考案は、部品形状が簡素化されていると共に
上記両者の特長を兼ね備え電池内圧の変化に伴う
弁動作圧の操作性と、減圧時の逆止性の特性を向
上させた信頼性のある密封構造をもつた排気弁を
提供することを目的とするものである。 The present invention has a simplified part shape, combines the above two features, and has a reliable seal that improves operability of valve operating pressure in response to changes in battery internal pressure and non-return characteristics when pressure is reduced. The object of the present invention is to provide an exhaust valve having a structure.
課題を解決するための手段

前記弁体１を前記台座２に押圧する弁押えカバー

外周面に連接する第１の傾斜面とよりロート形状

角は、前記第１の傾斜面の傾斜角よりも大きく
し、前記弁体１は、その底面外周部が前記第１の
傾斜面に当接する大きさとしたものである。Means for Solving the Problems In order to achieve the above object, the exhaust valve for a storage battery of the present invention includes a valve body 1 made of an elastic member, a pedestal 2,
The exhaust valve for a storage battery is composed of a valve retainer cover 4 that presses the valve body 1 against the pedestal 2, and the valve body 1 has a flat bottom surface and a concave curved surface 5 on the circumferential surface.
The pedestal 2 has an exhaust hole 3 in the center, a second inclined surface surrounding the exhaust hole 3, and an outer periphery of the second inclined surface. The valve retainer cover 4 forms a funnel shape with a first inclined surface connected to the gas discharge port 7.
The angle of inclination of the second inclined surface with respect to the horizontal plane is larger than the angle of inclination of the first inclined surface, and the outer circumference of the bottom surface of the valve body 1 is in contact with the first inclined surface. The size is such that they touch each other.
作 用
本考案は、弁体１と当接する台座２の傾斜面を
小さくしているため、弁体１と台座２との密着性
を高めることができ、弁動作圧の調整が容易に行
える。また減圧時には、電池内部への引きつけ力
がよわくても弁体１と台座２との接触面は十分に
増加するため、逆止性もすぐれている。Function: Since the present invention reduces the slope of the pedestal 2 that contacts the valve body 1, the close contact between the valve body 1 and the pedestal 2 can be improved, and the valve operating pressure can be easily adjusted. Further, when the pressure is reduced, even if the attraction force to the inside of the battery increases, the contact surface between the valve body 1 and the base 2 increases sufficiently, so that the non-return property is also excellent.
さらに傾斜角の大きい第２の傾斜面を設けるこ
とにより、弁体１と台座２との接触面を、カバー
の押し圧や弁体１、台座２のばらつきに関係なく
一定にすることができ、弁動作圧のばらつきを少
なくすることができる。 Furthermore, by providing a second inclined surface with a large inclination angle, the contact surface between the valve body 1 and the pedestal 2 can be made constant regardless of the pressing force of the cover or variations in the valve body 1 and the pedestal 2. Variations in valve operating pressure can be reduced.
実施例
以下本考案の一実施例を第３図、第４図を用い
て説明する。Embodiment An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.
第３図に示す底面が平面をなした略円錐形のゴ
ム等からなる弾性弁体１が、第４図に示すように
逆円錐形（浅い杯形）の台座２に嵌着されたとき
環状の弁体圧着領域Ａ−Ｂにほぼ均等な圧力が作

形成したものである。このとき弁体圧着領域Ａ−
Ｂの距離（幅）は、２mmが望ましく、２mm以下に
なると密着の度合にバラツキを生じ易く、逆に大
きすぎると弁体の圧着関与面積が大きくなり、強
い開弁圧力が必要となる傾向がある。 When an elastic valve body 1 made of rubber or the like having a substantially conical shape with a flat bottom as shown in FIG. A gentle concave curved surface 5 is formed on the circumferential surface of the elastic valve body 1 so that a substantially uniform pressure acts on the valve body crimping area A-B, and the peripheral edge of the bottom surface of the valve body 1 is pressed against the pedestal 2. It is. At this time, the valve body crimping area A-
The distance (width) of B is preferably 2 mm; if it is less than 2 mm, the degree of adhesion tends to vary; on the other hand, if it is too large, the area involved in crimping of the valve body becomes large, and strong valve opening pressure tends to be required. be.
排気弁としての密着度は、電池内圧が加圧また
は平衡圧の場合には、第４図の状態であるが、減
圧時には、弁は、弁座側へ引かれ、弁と弁座の接
触面積が増えるため高い信頼性が得られる。 The degree of closeness as an exhaust valve is as shown in Figure 4 when the battery internal pressure is pressurized or at equilibrium pressure, but when the pressure is reduced, the valve is pulled toward the valve seat, and the contact area between the valve and the valve seat is increases, resulting in high reliability.
弁の台座２は逆円錐形状で水平面に対して弁体
圧着領域Ａ−Ｂが傾斜角度θ＝１〜3゜をもつ構造
とし、Ｂから弁体の中心に形成した排気開孔部３
へは更に大きな角度をもつて沈み込ませてある。
この弁体圧着領域Ａ−Ｂの傾斜角度θが1゜よりも
小さい場合には、弁体１の加圧時の沈みしろが少
なくなり、弁圧力を予定した数値内に調整するこ
とが困難になるばかりでなく、弁体１の沈みを大

る。即ち線接触密封になるおそれがある。またθ
が3゜を超えると弁体１の変形が大きくなり、弁体
１の変形疲労が激しくなつて寿命が短かくなるお
それがある。 The valve pedestal 2 has an inverted conical shape and has a structure in which the valve body crimping area A-B has an inclination angle θ = 1 to 3 degrees with respect to the horizontal plane, and an exhaust hole 3 formed from B to the center of the valve body.
It is sunk at an even larger angle.
If the inclination angle θ of the valve body crimping area A-B is smaller than 1°, the amount of room for the valve body 1 to sink when pressurized will be small, making it difficult to adjust the valve pressure within the expected value. Not only this, but if the valve body 1 sinks too much, the edge A' of the valve body 1 may rise at point A, making it impossible to achieve uniform pressure bonding between areas A and B. In other words, there is a risk of line contact sealing. Also θ
If it exceeds 3 degrees, the deformation of the valve body 1 will become large, and the deformation fatigue of the valve body 1 will become severe, which may shorten its life.
領域のうち内側圧着境界部Ｂから台座２の中心
の排気開孔部３へ向つての傾斜角度は、このθよ
りも大きい傾斜角度を必要とし、θより5゜〜10゜
大きい傾斜が弁１の必要以上の台座への圧着をな
くす上で望ましい。 The angle of inclination from the inner crimping boundary part B of the region toward the exhaust opening 3 at the center of the pedestal 2 needs to be larger than this θ, and the angle of inclination 5° to 10° larger than θ is required for the valve 1. This is desirable in order to eliminate unnecessary crimping to the pedestal.
更にカバー４の固定圧着状態を変え、圧着を高
めれば、動作圧力を高め、圧着を低くすれば、動
作圧力を低く設定することもできる。 Furthermore, by changing the fixed crimping state of the cover 4 and increasing the crimping, the operating pressure can be increased, and by decreasing the crimping, the operating pressure can be set low.
第４図中６は弁１の押えカバー４に設けた弁１
の突起を嵌入させる凹部、７はガス排出口であ
る。 6 in Fig. 4 is the valve 1 installed on the presser cover 4 of the valve 1.
The concave portion 7 into which the protrusion is fitted is a gas discharge port.

増加するため、逆止性もすぐれている。Effects of the invention In the present invention, since the slope of the pedestal 2 that contacts the valve body 1 is made smaller, it is possible to improve the adhesion between the valve body 1 and the pedestal 2, and the valve operating pressure can be easily adjusted. . Further, when the pressure is reduced, even if the attraction force to the inside of the battery increases, the contact surface between the valve body 1 and the base 2 increases sufficiently, so that the non-return property is also excellent.
