본 발명은 납축전지의 내부로부터 발생되는 가스를 외부로 배출시키는 납축전지의 가스배출 밸브에 관한 것으로, 더욱 상세하게는 밸브에 방폭필터를 일체로 결합시켜 납축전지의 조립공정을 단순화시킴으로써 생산성을 향상시킬 수 있게 한 납축전지의 가스 배출밸브에 관한 것이다.The present invention relates to a gas discharge valve of a lead acid battery for discharging the gas generated from the inside of the lead acid battery to the outside, and more particularly, to improve productivity by simplifying the assembly process of the lead acid battery by integrally connecting the explosion-proof filter to the valve. To a gas discharge valve of a lead acid battery.

일반적으로 납축전지는 방전시 양극판인 과산화납이 이에 포함되어 있는 전해액의 수소와 결합하여 물이 생기고, 과산화납 속의 납은 전해액의 황산기와 결합하여 황산염을 형성하여 황산납이 되며, 음극판인 해면상납은 양극판과 같이 황산납이 된다.In general, lead-acid batteries produce water by discharging lead peroxide, which is a positive electrode plate, with hydrogen in the electrolyte solution contained therein, and lead in lead peroxide combines with sulfuric acid of the electrolyte to form sulfate, resulting in lead sulfate. Silver becomes lead sulfate like a positive plate.

그리고 충전시에는 상기의 방전과 반대로 외부로부터 충전전류가 흘러들어오게 되므로 방전에 의하여 황산 납으로 변한 음극판과 양극판의 작용물질은 납과 황산기로 분해되고 전해액 속의 물은 산소와 수소로 분해되고, 분해된 황산기의 수소의 결합에 황산이 되어 전해액으로 환원된다.During charging, the charging current flows from the outside as opposed to the above discharge. Therefore, the functional materials of the negative electrode plate and the positive electrode plate which are changed into lead sulfate by discharge are decomposed into lead and sulfate, and the water in the electrolyte is decomposed into oxygen and hydrogen. Sulfuric acid is bonded to the hydrogen of the sulfuric acid group to reduce sulfuric acid.

상기와 같은 화학 반응시 물의 가수분해에 의하여 양극에서는 2H2O→O2+4H++4e- 반응으로 산소가 발생되고, 음극에서는 4H+(aq)+4e-→2H2 반응으로 수소가 발생되기 마련이다.During the chemical reaction as described above, oxygen is generated by the reaction of 2H 2 O → O 2 + 4H + + 4e-by the hydrolysis of water, and hydrogen is generated by the reaction of 4H + (aq) + 4e-→ 2H 2 by the cathode.

이렇게 발생된 가스(산소, 수소 및 전해액의 증기포함)는 납축전지의 내부의 압력을 증가시키게 된다.The generated gas (including oxygen, hydrogen and the vapor of the electrolyte) increases the pressure inside the lead acid battery.

납축전지의 내부 압력 증가는 납축전지 게이스의 변형은 물론 납축전지의 Increasing the internal pressure of lead acid batteries can lead to deformation of lead acid battery

성능에도 영향을 미치게 되어 납축전지의 내부 압력을 일정한 수준으로 유지시킬 필요가 있다.It also affects the performance, and it is necessary to maintain the internal pressure of the lead acid battery at a constant level.

납축전지의 내부압력을 일정하게 유지시킬 수 있게 하기 위하여 납축전지의 메인커버에 가스를 외부로 배출시킬 수 있게 하는 통공을 형성시키고, 상기 통공에 가스배출밸브를 설치시키며, 가스배출밸브의 외측에 가스배출로를 연결시켜 납축전지의 내부압력을 일정하게 유지시킬 수 있게 하였다.In order to keep the internal pressure of the lead acid battery constant, the main cover of the lead acid battery is provided with a through hole for discharging the gas to the outside, and the gas discharge valve is installed in the through hole, and the outside of the gas discharge valve By connecting the gas discharge path, the internal pressure of the lead acid battery can be kept constant.

또한 납축전지의 내부에서 발생되는 가스는 폭발의 위험성이 높기 때문에 점화불꽃이 가스배출로 및 배출밸브를 통하여 납축전지의 내부로 유입되는 것을 차단하는 방폭필터를 가스배출로의 입구부위에 설치시켜 왔다.In addition, since the gas generated inside the lead acid battery has a high risk of explosion, an explosion-proof filter that blocks the ignition flame from entering the lead acid battery through the gas discharge path and the discharge valve has been installed at the inlet of the gas discharge path. .
