Sealing device and sealing method for wall penetration of negative pressure bin test pipeline

The invention belongs to the technical field of tests, and relates to a sealing device and a sealing method for wall penetration of a negative pressure bin test pipeline. The sealing device comprisesa sealing plate 1, a sealing gasket 2, a plug 6 and a bolt 5. The sealing device can conveniently and effectively enable a tested piece to lead out a cable and the pipeline to penetrate through a boxbody wall plate of a negative pressure bin, the negative pressure bin does not leak air, the negative pressure environment of a test region is not influenced, and the test stability and reliability are ensured. 本发明属于试验技术领域，涉及一种负压环境试验箱体线缆与管路穿壁密封方法及密封装置。密封装置包括密封板1、密封垫2、堵头6和螺栓5。该装置能够便利、有效地使被试件引出线缆与管路穿过负压仓箱体壁板后，负压仓不漏气，不影响试验区负压环境，确保试验稳定与可靠。
