The invention discloses an aircraft fuel tank sediment discharging tool which comprises a sleeve, a pin shaft and an ejector rod are arranged at one end of the sleeve in a radial penetrating mode, one end of the ejector rod is in radial threaded connection with the pin shaft, the other end of the ejector rod is exposed out of the sleeve, the sleeve of the aircraft fuel tank sediment discharging tool is connected with the ejector rod through the pin shaft, and a sediment discharging valve of a fuel tank is triggered through the ejector rod. The excretion liquid is drained into the sleeve through the ejector rod and then is led into the collector through the sleeve or the ejector rod. The ejector rod is withdrawn after collection, and the ejector rod is taken away after the sediment discharging valve is closed, so that non-contact sampling collection is realized, the sampling collection efficiency is improved, pollution diffusion is avoided, and sanitary maintenance is facilitated. The anti-slip part prevents the sleeve from slipping in the sampling process, and the force application ejector rod can conveniently trigger the precipitation valve.

    本发明公开了一种飞机燃油箱放沉淀工装,包括:套管,套管的一端径向穿设有销轴,顶杆,顶杆的一端与销轴径向螺纹连接,顶杆的另一端外露于套管,该飞机燃油箱放沉淀工装的套管通过销轴连接顶杆,通过顶杆触发油箱的放沉淀阀,排泄液经顶杆引流进入套管,再由套管或顶杆引入收集器。收集后收回顶杆,待放沉淀阀封闭后取走即可,实现了无接触的采样收集,提高取样收集效率同时避免了污染扩散,利于卫生维护。防滑部避免采样过程中套管发生脱滑,便于施力顶杆触发放沉淀阀。
