The invention relates to the technical field of airport transport vehicles, in particular to a manual emergency blow-down device for an aircraft sewage truck, which comprises a ball valve, a driving assembly and a manual assembly, the manual assembly comprises a valve opening plate and a labor-saving rod, when the aircraft sewage truck runs normally, the ball valve is operated by the driving assembly to control automatic blow-down, and when the truck is in an abnormal state, the manual assembly is operated by the driving assembly. When the driving assembly stops being used, the labor-saving rod is inserted into the power-assisted connecting port, the labor-saving rod is rotated to drive the valve opening plate to rotate, then a valve element of the ball valve is rotated, the ball valve is opened for pollution discharge, different power-assisted connecting ports can be selected according to needs to open the ball valve for pollution discharge, the automatic pollution discharge requirement and the manual pollution discharge requirement are met at the same time, and manual emergency pollution discharge can be achieved in the abnormal state of the vehicle. The manual emergency pollution discharge operation is simple and convenient, the valve opening plate is provided with a plurality of power-assisted interfaces, a lengthened labor-saving rod is configured for operation, labor is saved, remote operation is achieved, and sewage is prevented from being splashed to the body of an operator.

    本发明涉及机场运输车辆技术领域,具体涉及一种飞机污水车手动应急排污装置,包括球阀、驱动组件和手动组件,手动组件包括开阀板和省力杆,在飞机污水车车辆正常运行时,球阀操纵由驱动组件控制自动排污,车辆异常状态下,驱动组件停止使用,省力杆插上助力连接口,转动省力杆带动开阀板转动,进而转动球阀的阀芯,打开球阀排污,可根据需要选择不同的助力连接口开启球阀排污,同时满足自动和手动排污需求,在车辆异常状态下,可通过手动应急排污;手动应急排污操作简便,开阀板设置多个助力接口,配置加长省力杆操纵,省力且远距离操作,避免污水溅到操作人员的身上。
