The present invention is to provide a valve for a hydrogen tank of a fuel cell vehicle, which connects a pilot plunger and a main plunger through a flexible connection bar, and includes a first open hole for communicating with a tank-side flow passage at the pilot plunger, a blocking body for blocking the tank-side flow passage, and a second open hole allowing the tank-side flow passage to communicate with a pipe-side flow passage. When the pilot plunger ascends by magnetic force in the state in which the first open hole communicates with the tank-side flow passage, the tank-side flow passage is blocked by the blocking body and subsequently communicates with the pipe-side flow passage via the second open hole, thereby reducing the size of a section in which a pressure difference occurs between the tank-side and pipe-side flow passages and reducing the time taken to eliminate the pressure difference. Therefore, stable supply of hydrogen from a hydrogen tank to a fuel cell can be secured.

    본 발명은 파일럿 플런저와 메인플런저를 플렉시블 재질의 연결바로 연결하고, 파일럿 플런저에 탱크측 유로와 연통되는 제1개방홀과 탱크측 유로를 차단하는 차단체와 탱크측 유로와 배관측 유로를 연통시키는 제2개방홀을 형성하여, 탱크측 유로와 제1개방홀이 연통된 상태에서 자기력에 의하여 파일럿 플런저가 점진적으로 상승될 때, 탱크측 유로가 차단체에 의하여 차단된 후, 탱크측 유로가 제2개방홀에 의하여 배관측 유로와 연통되도록 함으로써, 탱크특 유로와 배관측 유로 간의 차압이 발생하는 구간 및 차압이 해소되는 시간을 줄일 수 있고, 그에 따라 연료전지에 대한 수소탱크의 수소공급 안정성을 확보할 수 있도록 한 연료전지 차량의 수소탱크용 밸브를 제공하고자 한 것이다.
