Description

Pipeline centering adjusting device Technical Field The utility model belongs to the technical field of pipeline installation, and particularly relates to a pipeline centering adjusting device. Background Pipeline centering devices are key tools used in pipeline installation engineering to ensure that pipelines coincide with the center line of a sleeve or a supporting structure, and the design and technology of the pipeline centering devices need to be continuously innovated to adapt to different scene requirements. Common pipeline centering methods include ‌ air bags and ‌ retainer ring methods ‌ and ‌ air bags, wherein the air bags are uniformly arranged on the outer side of a sleeve wall, are mutually connected in parallel through air ducts and are finally converged on a one-way valve for connection. The balloon is inflated to position the pipeline in the casing, and the ‌ baffle ring method is to set baffle ring on the top of the casing wall to limit the pipeline to move and ensure the pipeline to be centered ‌ inside the casing. Chinese patent CN204611105U discloses a pipe centering stop device, it includes a pair of ferrule subassembly, the ferrule subassembly includes big semicircle staple bolt spare and little semicircle staple bolt spare, big semicircle staple bolt spare and little semicircle staple bolt spare coaxial arrangement, and little semicircle staple bolt spare sets firmly in big semicircle staple bolt spare upside.
