Embodiment
Be described in detail of the present utility model below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, aircraft fuel oil conduit high security connection set of the present utility model, can comprise gathering-device 2 and drainage valve 5.
Gathering-device 2 for the first conduit 1 is connected with the second conduit 3, and for collecting the fuel oil of the first conduit 1 and the second conduit 3 joint leaks.Wherein, gathering-device 2 leakage of oil ozzle can downwards or level (with the first conduit 1 of level in Fig. 1 or the second conduit 3 for benchmark) install.
Drainage valve 5 is connected with the leakage of oil ozzle of gathering-device 2 by row fistulae road 4.Particularly, be, under the fuselage of the below of aircraft fuel oil conduit (first conduit 1 and the second conduit 3) flexible joint oil spill gathering device 2, covering installs drainage valve 5 by arranging fistulae road 4.Wherein, the latus rectum on row fistulae road 4 can carry out the selection be applicable to as required, is preferably latus rectum and is more than or equal to 6mm in the present embodiment; Further, the leakage of oil ozzle of gathering-device 2 and row's fistulae road 4 latus rectum are also all chosen as and are more than or equal to 6mm.
Aircraft fuel oil conduit high security connection set of the present utility model, when aircraft utilization and flight, the fuel oil leaked fuel duct joint can be collected by gathering-device 2, and leakage of oil is closed in Seal cage (Seal cage of gathering-device 2, row fistulae road 4 and drainage valve 5 internal cavities) by drainage valve 5, ensure that fuel oil can not drain to internal body or outside, ensure aircraft utilization and flight safety; In addition, when preflight ground is safeguarded, fuel oil can also be discharged by opening drainage valve 5, checking whether the outlet of drainage valve 5 has oil, can judge that fuel duct connects whether leakage of oil, find that leakage of oil is got rid of in time.
Drainage valve 5 of the present utility model can adopt multiple applicable structure, and in the present embodiment, drainage valve 5 comprises drainage valve body, valve 6, valve base 8 and sealing gasket 9.
Drainage valve body interior have cavity and with the filler opening of cavity connects and oil outlet.
