The invention belongs to the technical field of aircraft gas pipeline maintenance, and particularly relates to an automatic liquid drainage device and method for a gas pipeline. Comprising a shell (1), an upper cover plate (2), a valve retainer ring (3), a drainage valve (4) and a spring (5), the upper cover plate (2) is fixedly connected with the upper end of the shell (1) in a sealing manner; the structure is simple, the water separation efficiency is high, when gas passes through, liquid water in the gas is separated in a centrifugal separation mode and a gravity separation mode, when the gas path is ventilated, the liquid discharge port is closed under the pressure effect to guarantee sealing of the gas path, and after the gas path is closed, the liquid discharge port is opened to discharge liquid automatically.

    本发明属于飞机气体管路维护技术领域,具体涉及一种气体管路自动排液装置及方法。包括壳体(1)、上盖板(2)、活门挡圈(3)、排液活门(4)、弹簧(5);所述上盖板(2)与所述壳体(1)上端密封固定连接;结构简单,分水效率高,气体通过时,利用离心分离和重力分离两种方式,分离气体中的液态水,当气路通气时,在压力作用下排液口关闭保证气路密封,当气路关闭后,排液口打开自动排液。
