The present invention relates to a fuel tank sealing valve which can easily solve an overpressure applied from a fuel tank or a canister. The fuel tank sealing valve comprises: a housing having a canister and a flow path connected to the fuel tank; a driving unit having a rod linearly moving when power is applied; an opening and closing unit coupled to the rod to open and close the flow path, and having a connection hole of which the center is penetrated to allow gas to flow; an opening and closing unit elastic member applying an elastic force so that the opening and closing unit closes the flow path; a relief unit provided in the flow path to open and close the connection hole, and having a penetration hole penetrated to allow gas to flow; and a relief unit elastic member applying an elastic force to the relief unit to close the connection hole. With this configuration, both the opening and closing unit and the relief unit, which easily solve the overpressure when overpressure is applied from the fuel tank or the canister, can be accommodated in the housing, thereby reducing the overall size.

    본 발명은 연료탱크 또는 캐니스터로부터 과압이 작용하면 이를 용이하게 해소할 수 있는 연료탱크 밀폐밸브에 관한 것으로, 캐니스터와 연료탱크에 연결되는 유로가 형성된 하우징과, 전원이 인가되면 직선 이동하는 로드가 구비된 구동부와, 상기 로드에 체결되어 상기 유로를 개폐하고 가스가 유동하도록 중심이 관통된 연통홀이 형성된 개폐부와, 상기 개폐부가 상기 유로를 폐쇄하도로 탄성력을 인가하는 개폐부 탄성부재와, 상기 유로에 구비되어 상기 연통홀을 개폐하고 가스가 유동하도록 관통된 관통홀이 형성된 릴리프부, 그리고 상기 릴리프부가 상기 연통홀을 폐쇄하도록 탄성력을 인가하는 릴리프부 탄성부재를 포함한다. 이러한 구성으로, 연료탱크 또는 캐니스터로부터 과압이 작용하면 이를 용이하게 해소하는 개폐부와 릴리프부를 하우징의 내부에 모두 수용할 수 있어 전체 크기를 줄일 수 있는 효과를 얻을 수 있다.
