本发明涉及一种自充气密封圈、筒段装卡工装、内壁保护及局部氧化方法,属于航天大型筒段结构技术领域,解决了现有技术中大型筒段使用常规密封圈或大型橡胶塞,安装非常困难,或氧化后无法拆卸;在大型筒段内部造成了大体积的空腔,无法正常氧化的问题。本发明提供一种自充气密封圈,包括密封圈壳体和填充物,密封圈壳体设置有进料口;填充物填充在密封圈壳体内,填充物为通过化学反应产生气体的化学反应物,产生的气体实现密封圈壳体的充气和膨胀;气体为二氧化碳、氧气中的一种或多种。实现了航天大型筒段内壁保护下进行局部氧化。

    The invention relates to a self-inflating sealing ring, a cylinder section clamping tool and an inner wall protection and local oxidation method, and belongs to the technical field of aerospace large cylinder section structures. The problems that in the prior art, a large cylinder section uses a conventional sealing ring or a large rubber plug and is very difficult to install or cannot be disassembled after being oxidized, a large-size cavity is formed in the large-size cylinder section, and normal oxidation cannot be achieved are solved. The self-inflating sealing ring comprises a sealing ring shell and filler, and the sealing ring shell is provided with a feeding port; the sealing ring shell is filled with the filler, the filler is a chemical reactant which generates gas through a chemical reaction, and the generated gas achieves inflation and expansion of the sealing ring shell; and the gas is one or more of carbon dioxide and oxygen. Local oxidation under the protection of the inner wall of the aerospace large cylinder section is achieved.
