Mechanical pipeline vibration isolation sealing device

Abstract

The invention discloses a mechanical pipeline vibration isolation sealing device and belongs to the technical field of sealing equipment. The mechanical pipeline vibration isolation sealing device comprises sealing caps oppositely arranged on the two sides of a partition plate. A vibration isolation sealing ring is attached to the outer wall of a pipeline. Compressing bottom plates are attached to the two sides of the vibration isolation sealing ring and connected with compressing screws. The compressing screws are in threaded connection with the sealing caps. The mechanical pipeline vibration isolation sealing device is remarkable in sealing effect, the vibration isolation sealing ring can effectively absorb and weaken the pulse of the pipeline, the rubber vibration isolation sealing ring can be replaced quickly from the two sides in an alternative mode when the elasticity of the rubber vibration isolation sealing ring is reduced, and pressure leakage is reduced to the greatest extent.

Description

technical field [0001] The invention relates to a pipeline sealing device, which belongs to the technical field of sealing equipment. Background technique [0002] When the pipe passes through a partition such as a steel plate, there are inevitably gaps between the pipe and the partition. If there are different pressure requirements on both sides of the partition, these gaps will cause pressure leakage on both sides of the partition, thus non-compliant. In addition, most of the current sealing devices use solid connections, and certain pulsations will inevitably occur in the pipeline due to the flow of fluid. This solid connection will cause the pulsation of the pipeline to be transmitted to the partition wall, causing unnecessary vibration and affecting the overall performance. Moreover, the adjustability of this method is poor. With the increase of service time, the sealing effect is getting worse and worse, and it cannot be adjusted on the basis of the original seal.

[0002] When the pipe passes through a partition such as a steel plate, there are inevitably gaps between the pipe and the partition. If there are different pressure requirements on both sides of the partition, these gaps will cause pressure leakage on both sides of the partition, thus non-compliant

In addition, most of the current sealing devices use solid connections, and the flow of fluid in the pipeline will inevitably produce certain pulsations.

This solid connection will cause the pulsation of the pipeline to be transmitted to the partition wall, causing unnecessary vibration and affecting the overall performance

Moreover, the adjustment of this method is poor. With the increase of use time, the sealing effect is getting worse and worse, and it cannot be adjusted on the basis of the original seal. Only the sealing device can be replaced, which is time-consuming, laborious and costly.
