Pipeline self-sealing structure and airplane comprising same

Abstract

The invention discloses a pipeline self-sealing structure and an airplane comprising the same, and relates to the technical field of engine maintenance. The pipeline self-sealing structure comprises a sleeve pipe, a valve and a spring, wherein the sleeve pipe is internally provided with an annular sealing boss, and the two ends of the sleeve pipe are used for connecting pipelines; the valve is of an annular sleeve structure, the side wall of an annular sleeve is provided with a through hole, the through hole communicates with one end surface of the valve, the end surface is defined to be a sealing end surface, and the valve is installed in the sleeve pipe and is in sliding fit with the inner wall of the sleeve pipe; and the spring is installed in the sleeve pipe, one end of the spring is fixed, the other end of the spring is in contact with the valve, the spring provides thrust for the valve on the basis of compression elastic force, and the sealing end surface and the side surface of the annular sealing boss are matched so that a sealing effect can be achieved. The pipeline self-sealing structure and the airplane comprising the same have the advantages that when the connecting pipelines needing to be maintained are assembled and disassembled, oil pollution and leakage can be avoided, so that ground crew conduct operating conveniently and quickly, and the engine maintenance is improved.

Description

technical field [0001] The invention relates to the technical field of engine maintenance, in particular to a pipeline self-sealing structure and an aircraft with the same. Background technique [0002] In recent years, with the successful development of many new products, some models have been gradually put into use, and designers have gradually realized the importance of aero-engine reliability, manufacturing and assembly process, product maintainability and comprehensive support. According to the installation and maintenance characteristics of the current engine and aircraft, during the assembly and disassembly process of the pipeline structure between the engine and the aircraft, because the pipeline interface is not easy to be blocked in time, fuel, lubricating oil, etc. are often splashed onto the aircraft port cover or the airport ground, sometimes It may even stain the clothes of the ground crew, which is inconvenient for operation and maintenance, and increases the ...
