The invention provides a high-fault-tolerance splicing connection structure of a ventilation pipeline. The high-fault-tolerance splicing connection structure comprises a pipe body assembly, a companion flange, a sealing element and a flexible connection assembly, the pipe body assembly comprises a first pipe body and a second pipe body, the companion flange comprises a first flange and a second flange, the pipe body assembly and the companion flange are connected through a single-side flexible connection assembly or a double-side flexible connection assembly, the sealing element is an elastic body with a structure shaped like a Chinese character ' hui ', and sealing between the large end of the first flange and the large end of the second flange is achieved through compression deformation. Through the flexible connection component, the overall structure is compact, the weight is light, the installation error caused by accumulated deviation of the axis of a large-size ventilation pipeline is compensated, the ground installation efficiency is greatly improved, meanwhile, the problem that a traditional hard connection assembly cannot bear the severe upward orbit injection mechanical environment of a space station or other manned spacecrafts is solved.

    本发明提供了一种通风管路的高容错拼装连接结构,包括管体组件、配对法兰、密封元件和柔性软连接组件,其中,所述管体组件包括第一管体和第二管体,所述配对法兰包括第一法兰和第二法兰,管体组件与配对法兰为单侧柔性软连接组件连接或双侧柔性软连接组件连接,所述密封元件为“回”形结构弹性体,通过压缩变形实施第一法兰和第二法兰大端之间的密封。通过柔性软连接部件,整体结构紧凑,重量轻,补偿了大尺寸通风管路轴线累计偏差造成的安装误差,极大提高了地面安装效率,同时解决了传统硬连接组件无法承受空间站或其他载人航天器上行入轨恶劣力学环境的问题。
