The invention belongs to the technical field of fire extinguishing aircraft design, and discloses an aircraft water tank filling device and a working method.The aircraft water tank filling device is characterized in that a pipeline assembly is connected with a filling port of a ground water pipe through a clamping key assembly, and a one-way valve assembly is arranged; when water injection is stopped, the valve body restores to the initial position under the action of the spring, the water injection function of the water tank can be achieved, water in the water tank after injection does not flow back, and through the arrangement of the clamping key assembly, the requirements that the water tank is in quick butt joint with a ground water pipe, automatic locking is achieved, and overflowing is avoided during water injection can be met. Design components are few, the structure is reliable, and use is safe.

    本发明属于灭火飞机设计技术领域,公开了一种飞机水箱加注装置及工作方法,本发明通过卡键组件将管道组件与地面水管的加注口相连接,通过单向阀组件的设置,在注水时,高压水流将单向阀阀体冲开,水流将从阀体周圈流入水管直至进入水箱中,当停止注水后,在弹簧作用下,阀体恢复至初始位置,能够实现水箱的注水功能,并且满足加注后水箱中的水不逆流,通过卡键组件的设置,能够满足与地面水管快速对接且自动锁定,注水时不溢流,设计构件较少、结构可靠、使用安全。
