Description

Be applied to vacuum apparatus's antidetonation metal collapsible tube

Technical Field

Background

The domestic nuclear equipment and the cryogenic technology basically adopt a vacuum system, and mainly have good stability, safety and reliability. The vacuum system has extremely high requirement on sealing performance, the system is driven to run mainly by the vacuum pump, and the vacuum pump can vibrate under the traction action during normal work. If the vacuum pump is connected with the vacuum pipeline by adopting the hard pipeline, the vibration can lead the local stress of the hard pipeline to be overlarge so as to cause the welding seam or the pipeline to crack, and the whole system can not meet the vacuum requirement after the crack, so that the whole vacuum system is paralyzed, and even the irrecoverable accident can be caused. The vacuum pipeline requirements of the nuclear industry system in China are the most special industries, and the inlet and the outlet of a vacuum pump are basically connected with a vacuum pipeline by adopting metal hoses with good flexibility, good anti-seismic effect and high sealing performance requirements.
