Abstract

The invention discloses a cryogenic connector used for rocket tank propellant filling. The connector includes a connector body and a locking structure; the connector body includes a shell and a self-sealing structure arranged in the shell; the inner side of the shell has a channel for a liquid medium to flow in a first direction; the self-sealing structure is arranged on the channel to control theopening and closing of the channel; the two ends of the shell are respectively used for connecting a rocket body pipeline and a ground pipeline; and the locking structure is arranged on the outside of the shell and used for connecting the connector body and the rocket body pipeline. After the locking structure connects the connector body and the rocket body pipeline in place, the self-sealing structure can make the channel in an opening state, and the locking structure can be opened; after the connector body separates from the rocket body pipeline, the self-sealing structure can close the channel; and therefore, compared with the prior art, the connector is reasonable in structural design, stable in structure, convenient in operation, safe and reliable.

Description

technical field [0001] The invention relates to the field of liquid rockets, in particular to a low-temperature connector for propellant filling of a rocket tank. Background technique [0002] With the rapid development of the aerospace industry, various technologies involved in the rocket field have also achieved rapid progress. At present, rockets are the only vehicle for launching satellites into space. Therefore, the continuous reduction of rocket manufacturing and launch costs is the goal pursued by major commercial aerospace companies. [0003] Liquid rockets need to be pre-filled with cryogenic liquid fuel before launch, and during this process, it is often necessary to apply a cryogenic connector. At present, in order to realize the separation of the rocket and the filling pipeline at a specific moment, the low-temperature connector of the low-temperature filling system adopts a ball lock unlocking separation structure and a plug-in pull-out separation structure. T...
