Title:
SEALING SYSTEM FOR USE IN VACUUM PIPELINE OF HIGH-SPEED TRAIN
Document Type and Number:
WIPO Patent Application WO/2019/218378
Kind Code:
A1
Abstract:
A sealing system for use in a vacuum pipeline of a high-speed train, comprising a first connecting mechanism (1) and a second connecting mechanism (2), the first connecting mechanism comprising a fixed base (11) penetrated through the middle by a channel, a left valve body (12) and a right valve body (13), and a drive mechanism (14), a first rail (15) being laid horizontally in the channel of the first connecting mechanism, and a second rail (21) being mounted horizontally in a channel of the second connecting mechanism and being used for though-connection to the first channel; and an avoidance groove (151) used for smooth opening and closing of the left valve body and the right valve body is disposed between the two opposite end faces of the first rail and the second rail. The present sealing system for use in a vacuum pipeline of a high-speed train, by means of the synchronous rapid opening and closing of the left valve body and the right valve body, can quickly achieve sealing of the vacuum pipeline; in addition, as the first rail and the second rail do not move with the opening and closing of the left valve body and the right valve body, after the left valve body and the right valve body are opened, the reliability of the travel of the high-speed train is greatly improved.
