A connection device for eliminating three-way vibration of pipe joints

Abstract

The invention provides a connection device for eliminating three-way vibration of a pipeline interface, which mainly includes a pipeline A, a pipeline B, a sealing sleeve, a three-way damper, a sealing ring and a connecting pipe. Its characteristic is that the three-way shock absorber compensates for misalignment displacement. The invention quickly discharges excess fluid at the sealing ring through the oil return hole and ensures the force balance of the sealing ring; realizes axial and radial vibration elimination and eliminates axial and radial displacement through the three-way damper, and ensures the sealing of the pipe interface. Cut off the vibration transmission and protect the connected pipe; eliminate the movement resistance of the radial buffer block and the axial buffer block through the vent hole; limit the stroke of the axial buffer block and the radial buffer block through the stopper and prevent them from completely entering or moving out of the three-way Shock 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...
