The present invention relates to a safety valve apparatus connected to a regulator of a hydrogen tank, comprising: a regulator (20) having an entrance flow path (22), an exit flow path (23), and a valve flow path (24) communicating with a pressure reduction chamber (21) and a pressure reduction body (25); a safety valve (30) coupled to the valve flow path (24) of the regulator (20) by interposing a spring (34), and having a setting screw (35) changing the elastic force of the spring (34); and an end cap (40) mounted to prevent the random rotation of the setting screw (35). Accordingly, the present invention is able to precisely set the pressure of a pressure valve in a system, which reduces the pressure of and supplies hydrogen to a hydrogen tank, simplifying removal of residual pressure and maintaining the setting pressure in the maintenance process to improve safety and convenience.

    본 발명은 수소탱크의 레귤레이터에 연계되는 안전밸브 장치에 있어서: 감압실(21)과 감압체(25)에 연통되는 입구유로(22), 출구유로(23), 밸브유로(24)를 갖춘 레귤레이터(20); 상기 레귤레이터(20)의 밸브유로(24)에 스프링(34)을 개재하여 결합되고, 스프링(34)의 탄성력을 변동하는 세팅스크류(35)를 구비하는 안전밸브(30); 및 상기 세팅스크류(35)의 임의 회전을 방지하도록 장착되는 엔드캡(40);을 포함하여 이루어지는 것을 특징으로 한다. 이에 따라, 수소탱크의 수소를 감압하여 공급하는 계통에서 압력밸브의 압력을 정확하게 세팅할 수 있고 정비 과정의 잔압 제거와 세팅 압력 유지가 용이하여 안전성과 편의성을 향상하는 효과가 있다.
