The invention relates to the technical field of aircraft fuel oil systems, and discloses a safety valve which comprises a shell, a valve element, a valve element and a valve element. The valve is restrained in the inner cavity of the shell in a sliding mode and used for opening or closing the inlet, a sealing groove is formed in the end, close to the inlet, of the valve, the sealing groove is provided with a sealing ring, the sealing ring is used for sealing the inlet, a gap is reserved between the sealing ring and the sealing groove, and the end, away from the inlet, of the valve is connected with an elastic piece used for applying pre-tightening force; according to the safety valve, the possibility that the safety valve cannot normally release pressure is effectively reduced, the stability of opening pressure release of the safety valve under the specified pressure is improved, the service life of the safety valve is prolonged, the safety valve is particularly suitable for the low-pressure working condition of an aircraft fuel system, and the safety and reliability of the aircraft fuel system after long-term storage of an aircraft are improved.

    本发明涉及飞行器燃油系统的技术领域,公开了一种安全阀,包括:壳体,设有连通内腔的进口、出口;活门,滑动约束于壳体的内腔,用于打开或关闭进口,活门靠近进口的一端开设有密封槽,密封槽设有密封圈,密封圈用于密封进口,密封圈与密封槽之间留有缝隙,活门远离进口的一端连接有弹性件,弹性件用于施加预紧力;本发明的安全阀,有效的降低了安全阀无法正常泄压的可能性,提高了安全阀在规定压力下开启泄压的稳定性,提高了安全阀的使用寿命,尤其适用于飞机燃油系统的低压工况中,提高了飞机在长期贮存后飞机燃油系统的安全性和可靠性。
