Abstract

The invention relates to a non-destructive cleaning connection device for aerospace hydraulic pipelines and a hydraulic pipeline cleaning method, belonging to the technical field of pipeline cleaning connection devices, and solves the problem that the existing hydraulic pipeline cleaning method is easy to cause damage to pipe joint threads and seals and increases The cost of cleaning the pipeline. The non-destructive cleaning connection device for aerospace hydraulic pipelines of the present invention is used for connecting hydraulic pipelines. The connecting device includes a sealing structure and a guiding structure. The sealing structure is arranged on the butt joint nut of adjacent hydraulic pipelines, and the sealing structure is a hollow cylinder. Shape, the middle of the sealing structure is a first hollow cylinder, the two sides of the sealing structure are a second hollow cylinder, the butt joint nut is arranged in the first hollow cylinder, and the second hollow cylinder is connected with the butt joint nut. Hydraulic pipeline; the guide structure arranged on the outer surface of the sealing structure is used to fix the sealing structure. The invention improves the product quality of the hydraulic system and the pipeline cleaning efficiency, and reduces the pipeline cleaning cost.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning and connection devices, in particular to a non-destructive cleaning connection device for aerospace hydraulic pipelines and a hydraulic pipeline cleaning method. Background technique [0002] Hydraulic pipelines are responsible for connecting various hydraulic components in the hydraulic system and are an indispensable part of the hydraulic system. Aerospace hydraulic pipelines generally have to be manufactured, cleaned and tested before they can be put into assembly and use, among which pipeline cleaning is a particularly important link. There are nuts at both ends of the hydraulic pipeline to be cleaned. The traditional hydraulic pipeline cleaning method is easy to cause damage to the thread and seal of the pipe joint, which greatly increases the cleaning cost of the pipeline and affects the company's benefits. [0003] At present, in the cleaning process of aerospace hydraulic pipeli...
