The invention belongs to the technical field of vacuum, and discloses a vacuum pipeline high-speed magnetic suspension vacuum maintaining and pressure relief evacuation system, which comprises a vacuum pipeline (1) which can be isolated in a partitioned mode, each section of the vacuum pipeline is divided into a top channel (8) and a rail area (7) by a sealing top plate (10) from top to bottom, and a pressure relief hole set (11) is further formed in the sealing top plate; a pressure relief wedge group can move to enable the pressure relief hole set to be switched between an open pore passagestate and a closed pore passage state; and the top channel in each section of the vacuum pipeline has an independent vacuumizing function and an inflation and pressure relief function. By improving the structure of each component in the system, the arrangement mode and the cooperative work relationship among the components and the like, compared with the prior art, the system can solve the problems of vacuum maintenance under the normal operation condition of the vacuum pipeline high-speed maglev train and disaster prevention and evacuation under the fault condition.

    本发明属于真空技术领域,公开了一种真空管道高速磁悬浮真空保持与泄压疏散系统,包括能够进行分区式隔离的真空管道(1),真空管道的每个区间均自上而下被密封顶板(10)分隔成顶部通道(8)及轨行区(7),密封顶板上还开设有减压孔组(11);减压劈尖组能够移动使减压孔组在开放孔道与闭合孔道两种状态之间切换;真空管道每个区间内的顶部通道均具有独立的抽真空功能和充气泄压功能。本发明通过对系统内各组件的结构及它们之间设置方式、配合工作关系等进行改进,与现有技术相比能够有效解决真空管道高速磁悬浮列车正常运行工况时的真空保持与故障工况时的防灾疏散的问题。
