STRUCTURE OPTIMAL DESIGN OF THE SEAL RING OF THE INTELLIGENT PLUG IN HIGH-PRESSURE PIPELINE
The intelligent plugging technology in high-pressure pipelines is a novel plugging technology without drilling, the seal capacity and the clamping function which are respectively accomplished through the seal ring and the locking block are the key techniques of occluders. For the aim of designing the seals better to generate an effective sealing effect against the tube wall, firstly, the sealing structure of Intelligent Plug is introduced. Then the sealing condition of seals is modeled with ABAQUS software in this paper, including the sensitivity analysis and calculation about the relationships among contact surface and contact pressure and the influence of the structure of seals on them. The elitist non-dominated sorting genetic algorithm NSGA- II with ISIGHT software has been adopted to do the optimization. Optimum structural parameter is obtained and the performance of withstanding pressure difference is improved. The sealing performance of the intelligent plugging technology in high-pressure pipelines is guaranteed.
