The invention relates to a ventilation safety valve, which comprises a ventilation joint, a mounting flange used for fixing the ventilation safety valve on an aircraft fuel tank, a safety valve core, a safety valve body, sealing rubber, a guide sliding block, a spring, a pressure regulating nut and a positioning nut, sealing rubber vulcanized on the safety valve element is arranged in the safety valve body, three guide sliding blocks are arranged on the safety valve element, when the safety valve element moves, the friction force between the safety valve element and the safety valve body is reduced, and when the fuel tank of the aircraft is overpressure, the safety valve can be opened in time, and overpressure protection is achieved. A spring is arranged in the safety valve element and makes contact with the pressure adjusting nut, the safety valve element enables the sealing rubber to be tightly attached to the sealing face of the safety valve element to achieve sealing under the pretightening force of the spring, and the positioning nut is arranged at the tail end of the safety valve body, makes contact with the pressure adjusting nut and is used for positioning the pressure adjusting nut and preventing the pressure adjusting nut from loosening.

    一种通气安全阀,包括通气接头、用于将通气安全阀固定在飞行器油箱上的安装法兰、安全阀阀芯、安全阀阀体、密封橡胶、导向滑块、弹簧、调压螺母及定位螺母,其中,通气接头与安全阀阀体以螺纹形式连接,安全阀阀体内设置有硫化在安全阀阀芯上的密封橡胶,安全阀阀芯上设置有三个导向滑块,安全阀阀芯运动时,减小安全阀阀芯与安全阀阀体的摩擦力,在飞行器油箱超压时,安全阀能及时开启,实现超压保护;安全阀阀芯内设置有弹簧,弹簧与调压螺母接触,安全阀阀芯受弹簧预紧力将密封橡胶与安全阀阀芯的密封面贴紧实现密封,定位螺母设置在安全阀阀体尾端并与调压螺母接触,用于对调压螺母定位并防止调压螺母松动。
