Description

고압밸브용 가스누출 감지장치Gas leak detection device for high pressure valves
본 발명은 고압밸브용 가스누출 감지장치에 관한 것으로서, 보다 상세하게는 밸브에서 고압가스가 누출되는 것을 감지하여 알려줄 수 있는 고압밸브용 가스누출 감지장치에 관한 것이다.The present invention relates to a gas leak detection device for high-pressure valves, and more specifically, to a gas leak detection device for high-pressure valves that can detect and notify when high-pressure gas is leaking from a valve.
일반적으로 연료전지 차량에서 에너지 생성은 수소와 공기의 반응에 의한 역전기분해 현상에 의해 전류가 흐름으로써 전기 에너지가 생성된다. 이때 수소는 수소 저장 시스템의 수소 충전 라인을 따라 수소 저장 탱크에 저장된다. 상기 수소 저장 탱크에 저장된 수소는 전기 에너지 생성을 위해 수소 공급 라인을 따라 레귤레이터를 걸쳐 감압되고, 스택으로 공급된다.In general, energy generation in fuel cell vehicles is achieved by the flow of current through the reverse electrolysis phenomenon caused by the reaction between hydrogen and air, thereby generating electrical energy. At this time, hydrogen is stored in a hydrogen storage tank along the hydrogen charging line of the hydrogen storage system. The hydrogen stored in the hydrogen storage tank is depressurized through a regulator along the hydrogen supply line to generate electrical energy, and is supplied to the stack.
한편, 수소 저장 탱크에 구비되는 밸브는 고압 수소를 안내하기 위한 배관이 형성되는데, 배관 자체 손상이 발생하는 경우, 고압 가스가 누출되면서 폭발을 유발하는 문제점이 있다. 따라서, 이를 개선할 필요성이 요청된다.Meanwhile, the valve provided in the hydrogen storage tank forms a pipe to guide high-pressure hydrogen, but if the pipe itself is damaged, the high-pressure gas leaks and causes an explosion. Therefore, there is a need to improve this.
