Patent ID: 11761572

Abstract:
A pipeline separation device for liquid-propellant rocket comprising a first flange pipeline, a second flange pipeline, a clamping unit, a push-and-pull unit and an actuation unit. The first flange pipeline and the second flange pipeline dock along a first direction, a docking end surface docking with each other is limited by the clamping unit, and end surfaces opposite to each other after docking of the first flange pipeline and the second flange pipeline are respectively used for connecting with different medium pipelines; the actuation unit is used for pushing the push-and-pull unit so that the clamping unit relieves limit on the docking end surface. Being provided with a clamping unit and an actuation unit, the pipeline separation device for liquid-propellant rocket is capable of quickly pushing the clamping unit out when the actuation unit works, thereby relieving the limit on the first flange pipeline and the second flange pipeline.
