Embodiment 1

[0022] Figures 1-3 show that a specific embodiment of the present invention is: a hermetic door used in a vacuum pipeline system, including a partition wall 10 set in the vacuum pipeline 1 and a door opening 11 and a door cover on the partition wall 10 3. Partition wall 10 metope is hinged by one end of pin 2 and L-shaped hinge bar 4, and the other end of L-shaped hinge bar 4 is hinged with the back side of door cover 3 by pin 5. Its door cover 3 back side connects steel cable 8, and the other end of steel cable 8 links to each other with the winch 9 of door cover 3 back tops. The connection of steel cable 8 and door cover 3 back sides can adopt modes such as buckle, hook to connect flexibly, is convenient to the replacement of steel cable 8 like this.

[0023] The L-shaped hinge bar 4 of this example is positioned at the top of the door opening, and the winch 9 is positioned at the top of the door cover 3 backs. Also be provided with a Sui wheel 7 between door cover 3 and h...

Abstract

The invention discloses a sealing door in vacuum pipe system. The wall face of partition wall (10) is connected with one end of L-shape hinge bar (4) and the other end of L-shape hinge bar (4) is hinged with the back surface of door cover (3), which can cover the door hole (11). Steel cable (8) is connected at the back of door cover (3) and the other end of steel cable (8) is connected with hoister (9) at back of the door cover (3). The invention is provided with good isolation performance and small cubage occupied by door cover. The driving device can be set in the coffin corner place of vacuum pipe system. It is also provided with convenient use and simple structure.

Description

technical field [0001] The invention relates to a hermetic door used in a vacuum piping system. Background technique [0002] In the vacuum pipeline system, it is often necessary to set a hermetic door to seal and isolate a certain part of the vacuum pipeline or the space connected to it, so as to realize the conversion between the isolated part of the vacuum and the atmospheric pressure environment. Such as the vacuum pipeline transportation system, the maglev vehicle running in it has the unparalleled advantages of the existing transportation system. It has no noise, no exhaust gas emission, energy saving and environmental protection, which is not only beneficial to environmental ecological protection, but also saves a lot of land for construction Road; during the operation of the maglev vehicle, there is neither track friction resistance nor air resistance, and its speed exceeds that of an airplane, and its efficiency is high. However, when loading and unloading passenge...
