The invention discloses a pneumatic type cabin pressure adjusting system based on digital control for an airplane. Comprising a cabin pressure controller, an electric air pressure regulator, a two-position three-way electromagnetic valve, a pneumatic cabin pressure regulator and an exhaust valve, the electric air pressure regulator comprises a control valve and a limited corner motor mechanism used for controlling the opening degree of the control valve. The electric air pressure regulator is electrically connected with the control end of the limited angle motor mechanism and the control end of the two-position three-way electromagnetic valve. The feedback end of the limited angle motor mechanism is further electrically connected with the electric air pressure regulator through the position feedback assembly. And two passages of the two-position three-way electromagnetic valve are respectively communicated with a control cavity of the exhaust valve through the control valve and the pneumatic cabin pressure regulator. Take-off and landing of airports with different heights can be achieved, ground crew does not need to manually switch pressure systems before the airplanes take off, and the attendance efficiency of the airplanes is greatly improved.

    本发明公开了一种飞机用基于数字控制的气动式座舱压力调节系统。包括座舱压力控制器,电动气压调节器,两位三通电磁阀,气动式座舱压力调节器和排气活门;电动气压调节器包括控制活门和用于控制其开度的有限转角电机机构;电动气压调节器分别与有限转角电机机构和两位三通电磁阀的控制端电连接,有限转角电机机构的反馈端还经位置反馈组件与电动气压调节器电连接;两位三通电磁阀的其中两个通路分别经控制活门、气动式座舱压力调节器与排气活门的控制腔连通。本发明能实现不同高度机场起降,也无需飞机起飞前地勤人员手动切换压力制度,大幅提升飞机的出勤效率。
