Summary of the invention
For solving above-mentioned technical problem, the present invention provides a kind of quick detachable sealing and connecting device, seal with high-strength spring crush seal rubber ring, easy for installation, reliable operation, achieve plug-in auxiliary fuel tank oil transportation and the sealing of ventilation route, and can the effect that separates of fast-falling, reached satisfied sealing and effect that fast-falling separates.
In order to solve the technical problem of the present invention, the present invention is achieved by the following technical solutions: a kind of quick detachable sealing and connecting device, including fixing hoop 1, compensate flexible pipe 2, high-strength spring 3, spigot joint 4, rubber seal 5, locking nut 6 and joint shell 7, described fixing hoop 1 is installed on the two ends compensating flexible pipe 2, described joint shell 7 is fixed on the drop in beam below wing, described high-strength spring 3 is enclosed within the described outside of spigot joint 4, elastic force by high-strength spring 3, oppress described spigot joint 4, make described spigot joint 4 surfaces fitting tightly on described rubber seal 5, reach the effect sealed；On oil transportation that described locking nut 6 is arranged on auxiliary fuel tank is spigot joint, by adjusting lock nut 6 upper-lower position, regulate the sealing fastening dynamics of described rubber seal 5；Described joint shell 7 and spigot joint 4 junctions are the appropriate sphere-contact rotated so that described spigot joint 4 and the contact area maximization of described rubber seal 5, are greatly improved sealing effectiveness.
Preferably, described joint shell 7 and described spigot joint 4 junctions, it is designed to the sphere-contact 9 that can rotate in right amount, the top half of described quick detachable sealing and connecting device, i.e. fixing hoop 1, compensate flexible pipe 2, high-strength spring 3, spigot joint 4, joint shell 7, sphere-contact 9, can realize around described device center axis thereof, slewing area is 3 ° ~ 5 °.
Preferably, described compensation flexible pipe 2 is flexible material, compensates the plastic deformation surplus of flexible pipe 2, facilitate the connection of described quick detachable sealing and connecting device and wing drop in beam described in scalable.
Preferably, described spigot joint 4 can fit the most completely with rubber seal 5, reduce and force installation, increase the sealing of described auxiliary fuel tank 8 and wing junction.
After the instruction of input auxiliary fuel tank 8 sends, link on auxiliary fuel tank 8 and the hook below wing depart from, auxiliary fuel tank 8 is in free state, under the common effect of high-strength spring 3 elastic force and auxiliary fuel tank 8 gravity, spigot joint 4 can depart from rapidly with rubber seal 5, it is achieved the pipeline sharp separation that auxiliary fuel tank 8 is connected with wing.
Compared with prior art, the present invention obtains and provides the benefit that:
A kind of quick detachable sealing and connecting device disclosed by the invention, high-strength spring extruding rubber seal is used to seal, easy for installation, reliable operation, achieve plug-in auxiliary fuel tank oil transportation and the sealing of ventilation route, and can the effect that separates of fast-falling, reached satisfied sealing and effect that fast-falling separates.
