Pressure vessel pipeline sealing vibration isolation device

Abstract

The invention discloses a pressure vessel pipeline sealing vibration isolation device. The device structurally comprises a metal inner ring, a metal outer ring and an annular rubber cover, wherein themetal inner ring is arranged on a pipeline in a sleeving mode and is in sealing connection with the outer wall of the pipeline, the metal outer ring is connected with a pressure vessel body, the metal outer ring is arranged around the periphery of a pipeline extending-in hole of the pressure vessel body, a gap is formed between the metal outer ring and the metal inner ring, the annular rubber cover covers the gap between the metal outer ring and the metal inner ring, a plurality of carbon fiber lines are arranged in the rubber cover, and the two ends of each carbon fiber line are connected with the metal inner ring and the metal outer ring correspondingly. According to the device, the structure is compact, the static rigidity and the dynamic rigidity in the axial direction and radial direction of the pipeline are smaller than the required rigidity of vibration isolation between the pipeline and a pressure vessel, meanwhile, under the action of the carbon fiber lines, rubber which is used for vibration isolation can bear the pressure of the pressure vessel, and the rubber cannot be damaged by too large deformation caused by the fact that the rubber bears the high pressure, so thatthe rubber has a long service life.

Description

technical field [0001] The invention relates to a high-pressure sealing vibration-isolation structure, in particular to a high-pressure sealing vibration-isolation device suitable for use between a pressure vessel and a pipeline. Background technique [0002] A pressure vessel refers to a closed device that contains gas or liquid and carries a certain pressure. The body of the pressure vessel has a pipe access hole, and a pipe is provided in the pipe access hole through which the gas or liquid is input and output. The pipeline of the pressure vessel (the connection between the pressure vessel body and the pipeline) is usually equipped with sealing and vibration isolation devices. On the one hand, it is necessary to seal the high-pressure gas in the pressure vessel; Vibration isolation treatment avoids or weakens the interaction between the vibration of the pressure vessel body and the vibration of the pipeline. In current engineering practice, high-pressure gas sealing and ...

AI Technical Summary

Problems solved by technology

In current engineering practice, the sealing of high-pressure gas and pipeline vibration isolation are generally designed independently, while ordinary sealing rings are usually used for traditional sealing, which are easily damaged by vibration and difficult to meet high-pressure conditions.
