Description

무보수형 납축전지의 벤트밸브 조립체{Bent Valve Assembly of Lead Storage Battery}Bent Valve Assembly of Lead Storage Battery

본 발명은 정보통신용, 무정전 전원장치용 등으로 이용되는 무보수형 납축전지에 관한 것으로, 더욱 상세하게는 축전지의 수명연장과 전지간 성능균질화가 이루어지는 무보수형 납축전지의 벤트밸브 조립체에 관한 것이다.The present invention relates to a maintenance-free lead acid battery used for information communication, an uninterruptible power supply, and more particularly, to a vent valve assembly of a maintenance-free lead acid battery in which the life of the battery is extended and performance homogenization between batteries is achieved.

일반적으로 무보수형 납축전지는 정보통신 및 무정전 전원장치 등에 널리 이용되는 축전지로서, 충전시 전해액에 포함된 물의 분해시 발생하는 산소와 수소의 배출을 억제하여 이 산소와 수소를 물로 재결합시킴으로서 주기적인 물보충을 지양하는 구조를 갖추고 있다.In general, maintenance-free lead-acid batteries are widely used in telecommunications and uninterruptible power supplies. They are designed to prevent the release of oxygen and hydrogen generated during the decomposition of water contained in the electrolyte during charging and to recombine these oxygen and hydrogen into water to regenerate the water periodically. Equipped with a structure to avoid replenishment.

이와 같은 무보수형 납축전지는 전해액 격리판 함침형과 겔 전해질형으로 크게 2가지로 구분되며, 이들 전지의 파손은 주로 전해질내의 물고갈에 의하여 발생되는 바, 즉 충전시 전해액 물분해로 발생되는 산소와 수소의 배출정도는 밸브 조립체의 벤트밸브 개폐압에 의해 결정되므로, 상기 벤트밸브 제조시 축전지내의 가스 밀폐압을 정확히 설정해 주는 것이 납축전지 수명향상에 매우 중요한 기술로 대두되어 왔다.These maintenance-free lead acid batteries are classified into two types, namely, electrolyte separator impregnation type and gel electrolyte type. The breakage of these batteries is mainly caused by water depletion in the electrolyte, that is, oxygen generated by electrolyte decomposition during charging. Since the degree of discharge of hydrogen and hydrogen is determined by the vent valve opening and closing pressure of the valve assembly, precisely setting the gas sealing pressure in the battery when manufacturing the vent valve has emerged as a very important technique for improving the life of a lead acid battery.

또한 산업적으로 이용되는 무보수용 납축전지는 주로 군전지(群電池)형태로 적용되므로 각각의 전지의 벤트밸브 개폐압이 일정해야만 전지간에 균질한 전압특성을 나타내어 전지군 전체의 급격한 파손을 방지할 수 있게 된다.In addition, the maintenance-free lead acid batteries used industrially are mainly applied in the form of military batteries, so that the vent valve opening and closing pressure of each battery is uniform to show homogeneous voltage characteristics between the batteries to prevent sudden breakage of the entire battery group. Will be.

종래에 주로 이용되는 무보수형 납축전지의 벤트밸브 조립체를 살펴보면, 도 3에 도시된 바와 같이 벤트 구멍(74)이 형성된 밸브(76)를 누르는 상부캡(76)으로 이루어진 일본국 공개특허 1999-176,412호 또는 동국 공개특허 2000-277,081호 및 동국 공개특허 1987-128,435호등에 공지된 바와 같이 가스밀폐용 고무캡을 상부에서 일정압력으로 누르는 구조를 채택하였는 바, 이러한 벤트밸브 조립체는 고무캡에 걸려 있는 탄성응력을 극복하고 빠져 나갈 수 있는 가스압으로서 밸브의 개폐압을 설정하도록 되어 있는데, 이와 같은 종래 벤트밸브 구조들은 합성수지 사출부품들과 고무캡등의 제조시 발생하는 치수 공차에 의해 가스 밀폐압 범위가 크게 달라지는 문제점이 제기되었으며, 따라서 벤트밸브 제조후 전수검사시 설정 개폐압 범위를 벗어나는 벤트밸브가 다량 발생하거나, 합격품수를 늘리기 위해서 개폐압 설정범위를 넓게 책정할 경우에는 군전지내의 전지간 성능 불균질 현상이 과도하게 발생하는 문제점을 지니고 있다.Looking at the vent valve assembly of a maintenance-free lead-acid battery mainly used in the prior art, as shown in Figure 3, consisting of an upper cap 76 for pressing the valve 76 is formed with a vent hole 74, Japanese Patent Laid-Open No. 1999-176,412 As described in Korean Patent Application Publication No. 2000-277,081 and Dongkuk Patent Publication No. 1987-128,435, the gas sealing rubber cap is adopted to press a certain pressure from the top. It is to set the opening and closing pressure of the valve as a gas pressure to overcome the elastic stress, such a conventional vent valve structure is a gas tight pressure range due to the dimensional tolerances generated during the production of synthetic resin injection parts and rubber cap There is a problem that is greatly changed, so a large number of vent valves out of the set opening and closing pressure range during the full inspection after manufacturing the vent valve In the case of setting a wide range of opening and closing pressure to increase the number of accepted products, there is a problem that excessive performance heterogeneity between batteries in a group battery occurs.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 벤트밸브 제조후 밸브의 개폐압 검사시 벤트압 조절용 볼트(9)를 움직여 설정된 목표 개폐압으로 정밀조정해줌으로써 납축전지의 수명과 성능을 향상시키면서 동시에 전지간 균질한 성능을 나타내게 하는데 그 목적이 있다. 또한, 더 나아가 가스밀폐압이 상이한 다른 납축전지 등에도 손쉽게 호환 적용할수 있는 납축전지의 벤트밸브 조립체를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, by moving the vent pressure adjusting bolt (9) during the inspection of the opening and closing pressure of the valve after manufacturing the vent valve to precisely adjust the set target opening and closing life of the lead acid battery The purpose is to improve the performance and at the same time show homogeneous performance between cells. In addition, an object of the present invention is to provide a vent valve assembly of a lead acid battery that can be easily compatible with other lead acid batteries having different gas sealing pressures.

이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 무보수형 납축전지의 벤트벨브 조립체를 나타낸 단면도이고, 도 2는 도 1의 평면도이다.1 is a cross-sectional view showing a vent valve assembly of a maintenance-free lead acid battery according to the present invention, Figure 2 is a plan view of FIG.

본 발명은 축전지의 커버(1)에 설치되어 전조장착부(2)와 가스밀폐부(3)로 이루어진 납축전지의 벤트밸브 조립체에 있어서, 상기 전조장착부(2)에는 전조와의 밀착 및 밀폐를 위한 O링(4)이 장착되는 장착면(5)과 전조장착용 나사부(6)가 형성되어 있으며, 이 전조장착부(2)의 내부에 접착되는 가스밀폐부(3)에는 두개의 구멍(7b,7a)을 통과해온 가스의 배출압을 결정하는 고무캡(8)이 안착되고 이 고무캡(8)의 상부면에 압축응력을 가감하는 벤트밸브 개폐압 조절용 볼트(9)가 압착커버(10)에 삽입되어 고무캡을 누르는 구조로 되어 있다.The present invention provides a vent valve assembly of a lead acid battery, which is installed on a cover 1 of a storage battery and includes a roll mounting part 2 and a gas sealing part 3, wherein the rolling mount part 2 is used for close contact with and sealing of a rolling element. The mounting surface 5 on which the O-ring 4 is mounted and the roll mounting screw portion 6 are formed, and the gas sealing portion 3 bonded to the inside of the roll mounting portion 2 has two holes 7b, A rubber cap 8 for determining the discharge pressure of the gas that has passed through 7a) is seated, and a vent valve opening / closing pressure adjusting bolt 9 for applying or compressing a compressive stress to an upper surface of the rubber cap 8 is a crimping cover 10. It is inserted into and pressurized the rubber cap.

그리고 상기 전조장착부(2)의 하부에는 가스밀폐부(3)의 가스벤트구멍(7a)과 연통되는 가스의 배출통로인 다른 가스벤트구멍(7b)이 형성되어 있으며, 이의 상부 헤드쪽에는 상부커버 걸이용 홈(11)이 형성되어 있다.In addition, another gas vent hole 7b, which is a discharge passage of the gas communicating with the gas vent hole 7a of the gas sealing part 3, is formed in the lower part of the roll mounting part 2, and an upper cover is formed on the upper head side thereof. The hook groove 11 is formed.

두개의 가스벤트구멍(7b,7a)을 통과해온 가스는, 벤트밸브 개폐압 조절용 볼트(9)에 의해 상부면을 눌림으로써 가스밀폐압을 결정하는, 고무캡(8)을 통과하여 압착커버(10)에 형성되어 있는 가스벤트구멍(7c)으로 배출된다.The gas which has passed through the two gas vent holes 7b and 7a passes through the rubber cap 8 to determine the gas sealing pressure by pressing the upper surface by the vent valve opening / closing pressure adjusting bolt 9 and presses the pressing cover ( It is discharged to the gas vent hole 7c formed in 10).

또한 도 1과 도 2에 도시된 바와 같이 상기 전조장착부(2)의 헤드쪽에는 벤트밸브를 전조에 장착하기 용이하도록 육각형의 렌치홈(12)이 형성되어 있다.Also, as shown in FIGS. 1 and 2, a hexagonal wrench groove 12 is formed at the head side of the roll mounting part 2 to easily mount the vent valve to the roll.

따라서 본 발명은 가스밀폐부(3)의 벤트밸브 개폐압 조절용 볼트(9)를 이용하여 가스밀폐압을 결정하는 고무캡(8)의 압축정도를 손쉽게 조절할 수 있는 구조로 되어 있다.Therefore, the present invention has a structure that can easily adjust the degree of compression of the rubber cap (8) for determining the gas sealing pressure by using the vent valve opening and closing pressure adjusting bolt (9) of the gas sealing part (3).

상기와 같은 구조를 갖는 본 발명은 벤트밸브를 납축전지에 장착시킨 다음 벤트밸브 개폐압검사를 수행하면서 설정 목표치보다 높게 되면, 벤트밸브의 개폐압 조절용 볼트(9)를 풀어서 고무캡(8) 상부를 누르는 압력을 낮추는 반면, 설정목표치보다 낮을 경우 반대로 이 벤트밸브 개폐압 조절용 볼트(9)를 조여서 고무캡(8) 상부를 누르는 압력을 높여 설정된 목표 가스 밀폐압과 거의 유사하거나 동일하게 일치시킬 수 있도록 되어 있다.According to the present invention having the structure as described above, when the vent valve is mounted on the lead acid battery and then the vent valve opening and closing pressure test is higher than the set target value, the opening and closing pressure adjusting bolt (9) of the vent valve is released to the upper portion of the rubber cap (8). On the other hand, if the pressure is lower than the set target value, the pressure of the event valve opening / closing pressure adjusting bolt (9) can be tightened to increase the pressure to press the upper portion of the rubber cap (8) so that the pressure can be almost similar to or equal to the set target gas seal pressure. It is supposed to be.

상기와 같이 본 발명은 기존 벤트밸브의 조립체에서 야기되는 문제점, 즉 고무캡 및 사출부품들의 제조상의 치수 공차 등으로 인하여 가스의 설정 목표 밀폐압을 벗어나는 경우에 폐기하지 않고 이를 재조정할 수 있음에 따라 납축전지의 수명을 향상시키고 군전지의 전지간 성능 균질화를 향상시킬수 있으며, 더 나아가 요구되는 가스 밀폐압이 상이한 납축전지에도 벤트밸브를 호환 적용할 수 있는 잇점이 있다.As described above, the present invention can be readjusted without discarding the gas when it is out of the set target sealing pressure due to problems caused by the assembly of the existing vent valve, that is, the manufacturing dimensional tolerances of the rubber cap and the injection parts. It is possible to improve the life of lead acid batteries and to improve the performance homogenization of the batteries of military batteries. Furthermore, the vent valve can be interchangeably applied to lead acid batteries having different gas sealing pressures.
