Pipeline butt-joint device capable of adapting to adjustment

Abstract

The invention discloses a pipeline butt-joint device capable of adapting to adjustment. The pipeline butt-joint device capable of adapting to adjustment consists of a hose 1, a rotary shaft 2, a bracket 3, a hoop 4, a heat-insulation buffer layer 5, an adapting head 6, a lifting frame 7, an inclined support 8, a bottom plate 9 and a vertical rod 10. The device is used for a pipeline butt-joint system, wherein one end of the pipeline butt-joint system is fixed, and the other end of the pipeline butt-joint system has displacement, vibration and structural changes. In a using process, adapting heads of different structural forms are matched in structure and position. The lifting frame is adjusted in height, so that height errors of the bracket can be compensated. When one end of the hose has displacement, the bracket bound with the hose can freely rotate to relieve additional stress. The heat-insulation buffer layer is used for reducing heat conduction between medium and the bracket and reducing influences, on the pipeline system, of the vibration. With methods such as differential butt-joint, mounting error elimination, displacement amount accompanying adjustment, vibration absorption and heat insulation, the pipeline butt-joint device can be used for butting side structures and position changes, and can be applied to the pipeline engineering fields which need reducing vibration and carrying out heat insulation.

Description

technical field [0001] The invention relates to a pipeline butt joint device, which is suitable for liquid rocket cryogenic propellant filling system and pipeline systems in other engineering fields. Background technique [0002] The power system test is the largest ground test before the flight test of the newly developed rocket. It needs to actually fill the propellant and complete all the work during the ignition period. As a key component of the rocket power system test bench, the propellant filling system is connected with the rocket body tank through the docking device. For rockets that use cryogenic working fluid as propellant, the contraction force of the pipes in the cold state and the gravity of the medium make the pipes and brackets in the system face great challenges. If the force is directly applied to the interface such as the flange, it will affect the sealing of the interface, and in severe cases, it will cause the leakage of propellant, and even affect the ...
