The invention discloses an outboard installation type cabin safety valve comprising a modular excess pressure mechanism and a method. Comprising a shell (1), a diaphragm (2) is arranged in an inner cavity of the shell (1), and a knife edge valve (3) is arranged on the bottom face of the diaphragm (2). A cavity B is formed by the upper surface of the diaphragm (2) and the shell (1), a cavity A is formed between the inner side of the knife edge valve (3) and the shell (1), and an atmosphere cavity (4) communicated with the atmosphere is formed among the outer side of the knife edge valve (3), the bottom face of the diaphragm (2) and the shell (1). The cavity A is communicated with the cavity B through a hollow valve rod (5); and the cavity B is communicated with the residual pressure mechanism. The problems that a cabin safety valve installed outside a cabin is poor in control precision, product debugging is difficult, and the residual pressure value is prone to fluctuation under the high-altitude condition are solved.

    本发明公开了一种含模块化余压机构的舱外安装式座舱安全活门及方法。包括壳体(1),壳体(1)内腔设置有膜片(2),膜片(2)底面设有刀口活门(3);膜片(2)上表面与壳体(1)形成B腔,刀口活门(3)内侧与壳体(1)间形成A腔,刀口活门(3)外侧、膜片(2)底面及壳体(1)间形成连通大气的大气腔(4);A、B腔间经中空的活门杆(5)连通;B腔与余压机构连通。本发明解决了舱外安装的座舱安全活门控制精度较差、产品调试困难、在高空条件下余压数值容易波动的问题。
