Abstract

The invention provides a connecting device for eliminating three-direction vibrations of a pipeline interface. The connecting device mainly comprises a pipeline A, a pipeline B, a sealing sleeve, a three-direction vibration absorber, a sealing ring and a connecting tube. The connecting device is characterized in that dislocation displacement is compensated by the three-direction vibration absorber. According to the connecting device, by virtue of an oil return hole, excessive fluid at the sealing ring is quickly discharged and stress balance of the sealing ring is guaranteed; axial-direction and radial-direction vibration absorption as well as axial-direction and radial-direction displacement elimination are realized by virtue of the three-direction vibration absorber, so that the pipeline interface is guaranteed to be sealed, vibration transmission is cut off, and a connected pipe is protected; motion resistance of a radial-direction buffer block and an axial-direction buffer block is eliminated through a vent hole; and stroke of the axial-direction buffer block and the radial-direction buffer block is limited by a baffle block, and the axial-direction buffer block and the radial-direction buffer block are prevented from completely entering or moving out of a three-direction vibration absorber housing.

Description

technical field [0001] The invention relates to a connection device for eliminating three-way vibration of a pipeline interface, in particular to a fast discharge of excess fluid at the sealing ring through an oil return hole and ensuring a balanced force on the sealing ring; To eliminate vibration and eliminate axial and radial displacement, ensure the sealing of pipe joints, cut off vibration transmission, and protect the connected pipes; eliminate the movement resistance of radial buffer blocks and axial buffer blocks through vent holes; limit axial buffer through stoppers The stroke of the block and the radial buffer block and prevent it from completely entering or moving out of the three-way shock absorber shell belong to the technical research and development field of the pipeline connection device. Background technique [0002] Fluid transport pipelines are susceptible to vibration loads during work. Vibration loads cause displacement changes in the pipelines, so that...
