Vacuum heat insulation low-temperature connector

Abstract

The invention relates to a vacuum heat insulation low-temperature connector, which comprises a connecting base and a butt joint; a ball lock is arranged between the connecting base and the butt joint; the connecting base comprises a first inner pipe and a first outer pipe; the right ends of the first inner pipe and the first outer pipe are in sealed connection through a first taper pipe; the left end of the first outer pipe is in sealed connection with the first inner pipe through a first plugging piece; the first outer pipe is provided with a first vacuumizing pipe joint; the first inner pipe is coated with a first heat insulation layer; the butt joint comprises a second inner pipe and a second outer pipe; the left ends of the second inner pipe and the second outer pipe are in sealed connection through a second taper pipe matched with the first taper pipe; a first sealing ring is arranged between the second taper pipe and the first taper pipe; the right end of the second outer pipe is in sealed connection with the second inner pipe through a second plugging piece; the second outer pipe is provided with a second vacuumizing pipe connector; and the second inner pipe is coated with a second heat insulation layer. The vacuum heat insulation low-temperature connector provided by the invention has the advantages of being simple in structure, convenient to connect, reliable in sealing, good in heat insulation effect and capable of effectively avoiding the frosting and freezing phenomena.

Description

technical field [0001] The invention relates to a connector, in particular to a vacuum insulation connector used for low-temperature medium filling. Background technique [0002] In the field of aerospace, low-temperature connectors are used as functional components for the injection and release of low-temperature media in rockets, and they need to meet the requirements of stable connection and reliable shedding. However, the existing low-temperature connectors have the problems of complex structure and inconvenient connection in practical applications, especially after a long time of low-temperature medium filling, it is easy to generate frost and ice at the connection, resulting in unlocking, The shedding action could not be completed smoothly, which affected the safety of the rocket launch. Contents of the invention [0003] The purpose of the present invention is to provide a vacuum insulated cryogenic connector, which has the advantages of simple structure, convenien...
