Abstract

The invention discloses a low separation load joint with flexible self-compensation, and relates to a joint of an air supply connector and a liquid supply connector in a carrier rocket (a guided missile) which is more sensitive in rocket-ground separation load requirement, and high in falling separation reliability requirement. The provided joint aims to reduce separation load, has a butting automatic guide positioning function and an automatic flexible compensation function, and is capable of realizing separation without clamping stagnation, and improving butting and separation reliability. The joint comprises cooperatively installed socket and plug. The plug comprises a plug body, a fixing base, a guiding base and a spring. The socket comprises a sealing base and an outer sleeve. The plug body is provided with a hollow cavity structure. The front part of the plug body is a conical surface. The fixing base can be screwed in the plug body and cooperatively installed with the plug body.The guiding base is sheathed at the outer side of the fixing base. The spring is pre-compressed and installed between the plug body and the guiding base. The rear part of the sealing base is providedwith a conical surface structure which has the same inclination angle of the conical surface as the plug body. The rear part of the outer sleeve is sheathed at the outer side of the sealing base.

Description

technical field

[0001] The invention relates to a connecting piece, in particular to a joint used for a gas supply connector and a liquid supply connector in a launch vehicle (missile) which is sensitive to the load requirements of the rocket-ground separation and has high requirements on the reliability of the separation. Background technique

[0002] Air supply connectors and liquid supply connectors are usually installed in launch vehicles and missiles, but launch vehicles and missiles are sensitive to the load requirements for rocket-ground separation, and require high reliability for separation and separation. When supplying air or liquid, the connecting equipment generates axial separation load due to the separation load such as blind plate force. The higher the medium pressure and the larger the diameter, the greater the axial separation load. There are high requirements on the rigidity and strength of the connected parts, which will increase the size, volume, weight ...
