Abstract

This application relates to the technical field of aircraft assembly, and discloses a stress-relief installation method for quick-release clamps connected to conduits. Through the steps of pre-installation inspection, first stress-relief installation, second stress-relief installation, and final inspection and installation, it solves the problem of current conduit fastening During the installation process of the unloading clamp, the system pipeline may crack or leak oil during use due to excessive installation stress.

Description

technical field [0001] The present application relates to the technical field of aircraft assembly, in particular to a stress-relief installation method for quick-release clamps connected to conduits. Background technique [0002] In the design of aircraft system piping, considering the requirements of maintainability and operability, the standard parts of conduit quick release clamps are often used to connect adjacent conduits. Therefore, the installation quality of conduit quick release clamps has a great influence on the performance of the aircraft system. and reliability play an important role. This type of conduit quick-release clamp clamps the joint through the clamp, and through the V-shaped surface in contact with the joint, the radial clamping force is partially converted into the axial pulling force along the conduit, and the joints at both ends are close to each other under the action of tension. And press the sealing ring in the sealing groove to realize the sea...
