Problems solved by technology

However, most of the existing plugging technologies use inflatable or simple deformation of rubber materials for plugging operations, and it is difficult to implement plugging operations for large-diameter and high-pressure pipelines
Moreover, the radial expansion and contraction range of the current plugging equipment is extremely limited, resulting in very strict requirements on the radius of the inner plugging device in the pipeline plugging operation. If the damage occurs at the bend of the pipeline or there is a reducing tube in the pipeline, the existing The internal occluder cannot complete the occlusion task

Abstract

The invention discloses a modular reducing pipeline inner plugging device, a driving mechanism and a coordination ring. The plugging device comprises a sealing barrel, a pressing mechanism, universal joints and the like; and the pressing mechanism is of a deformable serial connection structure formed by connecting a plurality of reducing modules through universal joints and is installed in the sealing barrel. During plugging operation, the sealing barrel can be pressed on the inner wall of a pipeline through the reducing modules to complete sealing operation. According to a plugging system, a hydraulic system is adopted for providing power, and a complex gas supply system is not needed; and reducing mechanism bodies in the reducing modules adopt a plugging mode of combining spring steel and a sealing flexible material, so that the plugging device has very good structural strength and has higher plugging pressure than a common plugging device.

Description

technical field [0001] The invention relates to the technical fields of mechanical engineering and petrochemical industry, in particular to a modular variable-diameter pipeline internal blocker, a driving mechanism and a coordination ring. Background technique [0002] At present, the infrastructure facilities of the domestic oil and gas industry are basically complete, and the corresponding oil and gas pipelines have been in service for many years. Corrosion, damage, potential cracks and other problems will inevitably occur in pipelines as their service life increases. However, many pipe plugging devices have also been produced at present. The usual way to repair a pipeline after it has ruptured is to shut off the flow of liquid and then carry out repair work on the pipeline. However, most of the existing plugging technologies are inflatable or simply deformed rubber materials for plugging operations, and it is difficult to implement plugging operations for large-diameter ...
