The invention relates to the technical field of aviation cabin pressure regulators, in particular to a pressure release valve of a miniaturized airplane. Comprising a shell (1), a diaphragm assembly (3), a microswitch screw rod (4), a microswitch (5), an electric connector (20), a wire (21), a spring (22), an upper cover (13) and a pressure regulating screw sleeve (14). The pressure release function is controlled, meanwhile, the function of a'valve full-open 'indication signal is provided, in the state that the pressure release valve is fully opened, the diaphragm assembly moves upwards to press the microswitch contact, and the problem that the microswitch contact is in a long-term compression state, so that signals are abnormal is effectively avoided.
本发明涉及航空座舱压力调节器技术领域,具体涉及一种小型化飞机压力释放活门。包括:壳体(1)、膜片组合件(3)、微动开关螺杆(4)、微动开关(5)、电连接器(20)、导线(21)、弹簧(22)、上盖(13)、调压螺套(14)。在实现控制压力释压功能的同时并提供“活门全开”指示信号的功能,在压力释放活门全开的状态下,膜片组合件向上运动按压微动开关触点,有效避免了微动开关触点因长期压缩状态造成信号异常的问题出现。
