AI Technical Summary

Technical Problem

During live pipeline tapping and plugging operations, iron filings left inside the pipeline may cause the plugging to fail. Existing cleaning devices cannot completely eliminate the risk, and may even damage the sealing surface of the rubber cup under extreme conditions.

Method used

A device for removing iron filings left in a pressurized pipe opening is designed. It utilizes a sealing tee and an adsorption assembly, including a main support, a movable support, and a magnet, connected by a hinge shaft, to adsorb iron filings inside the pipe, especially those that have entered the downstream area.

Benefits of technology

It improves the range and efficiency of iron filings adsorption, reduces the risk of damage to the sealing surface of the rubber cup, avoids pipe blockage, and ensures the sealing performance and construction progress of the plug.

Abstract

The utility model discloses a device for removing scrap iron left in pipeline tapping under pressure, which comprises a plugging tee joint arranged at a pipeline tapping position, a plugging device is arranged on the plugging tee joint, a plugging rod of the plugging device extends inwards along the radial direction of a pipeline, the tail end of the plugging rod is connected with a main support, and the tail end of the main support is connected with a pipeline. A movable support is connected to the main support through a hinged shaft, and an adsorption assembly is arranged at the tail end of the movable support. The device for removing the scrap iron left after pipeline pressure tapping is simple in structure, convenient to use and capable of adsorbing the scrap iron entering the downstream of a pipeline due to pipeline pressure and solving the problem of plugging failure caused by the fact that the scrap iron damages the sealing face of the leather cup.
