The invention belongs to the field of sensitive elements of absolute pressure control mechanisms of aviation cockpit pressure regulators, and relates to a vacuum corrugated pipe assembly for an aviation cockpit pressure regulator, which comprises an upper cover (1), a lower cover (2) and a corrugated pipe (3), the upper cover is in a T-shaped step cylinder shape, and the lower cover is in an inverted T-shaped step cylinder shape. The upper cover lower section and the lower cover upper section are equal in diameter, and the corrugated pipe is arranged between the upper cover lower section and the lower cover upper section in a sleeved mode. The upper end of the corrugated pipe is connected with the upper cover side wall and the upper cover step surface through welding, and the lower end of the corrugated pipe is connected with the lower cover side wall and the lower cover step surface through welding; and vacuum seal welding is performed through the seal welding hole of the lower cover (2). The reliability of the pressure regulator is improved, automatic regulation of the cabin pressure is achieved, and the stability of the cabin pressure is effectively guaranteed.

    本发明属于飞机座舱压力调节器绝压控制机构的敏感元件领域,涉及一种用于飞机座舱压力调节器的真空波纹管组合件,包括上盖(1)、下盖(2)和波纹管(3)三个部分;所述上盖为“T”型台阶圆柱状,所述下盖为倒置的“T”型台阶圆柱状;上盖下段和下盖上段直径相等,所述波纹管套设在上盖下段和下盖上段之间;波纹管上端通过焊接与上盖侧壁和上盖台阶面连接,波纹管下端通过焊接与下盖侧壁和下盖台阶面连接;并通过下盖(2)封焊孔经真空封焊而成。本发明提高了压力调节器的可靠性,实现了座舱压力的自动调节,有效保证了座舱压力的稳定性。
