Embodiment Construction
[0032] Embodiments of the present invention will be described in more detail below in conjunction with the accompanying drawings.
[0033] A pipeline automatic separation joint, including a pipeline automatic separation joint, including a first joint 1 and a second joint 2, the first joint 1 is installed on an external fuel tank 3, and the second joint 2 is installed on an aircraft pylon 4 on.
[0034] See attached figure 1 , the first joint 1 includes a telescopic joint 11, a height adjustment nut 12, a bushing I13, a limit screw 14, a sealing ring I15 and a sealing ring II16. Put the sealing ring II16 into the sealing ring installation groove of the bushing I13; screw the height adjustment nut 12 into the upper thread of the bushing I13; insert the bottom of the telescopic joint 11 into the bushing I13, then rotate the telescopic joint 11 to make it go up The limit groove of the bushing is aligned with the limit screw mounting hole of the bushing I13; finally, screw the tw...

The invention discloses a pipe automatic separation joint which comprises a first joint and a second joint, wherein the first joint is installed on an exterior oil tank; the second joint is installed on an aircraft hanging rack; the first joint comprises a telescopic joint mouth, a height adjustment nut, a bushing I, a limit screw, a seal ring I and a seal ring II; when the height adjustment nut is rotated, the telescopic joint mouth can ascend or descend; the second joint comprises a slide joint mouth, a stroke adjustment nut, a bushing II, a spring and a rubber clamping ring; the stroke adjustment nut is used for adjusting the stroke of the slide joint mouth; and the second joint is connected with the first joint. The pipe automatic separation joint has the compensation function, and is free from the influence of clearance errors and position errors between the exterior oil tank and aircraft hanging rack. The joint adopts flexible connection, can bear the influence of vibrations, impact and deformation in the use process, and has the advantages of high connection firmness and high reliability. The joint can be automatically separated quickly without clamping stagnation.
Description
technical field [0001] The invention belongs to the technical field of aircraft fuel systems, in particular to a pipeline automatic separation joint. Background technique [0002] Due to the limitation of the internal space of the aircraft, the fuel capacity is often limited, which affects the flight range of the aircraft. In order to solve the above problems and increase the range of the aircraft, the current solution is to add an external fuel tank (auxiliary fuel tank) at an appropriate position (wing or fuselage) outside the aircraft. Some of these external tanks are droppable as required. The external fuel tanks that can be dropped are hung on the pylon of the aircraft for easy release. The external fuel tanks are equipped with fuel delivery pipes and booster pipes connected to the internal fuel system, and the fuel delivery pipes and booster pipes need to be connected to the internal pipelines through pipeline connector . When the external fuel tank is launched in t...
