摘要
针对现有管道抢修卡具存在变形大、堵漏速度慢、堵漏效果差等缺陷,基于相关的经典理论研究成果,完成了卡具的材料、本体、耳板、螺栓、密封材料等的优化,提出了改善卡具刚度的加强肋结构及注剂孔的合理布局。通过Pro/e软件建立了新型高压卡具的三维实体模型,对卡具的应力、应变、位移等进行了定量分析,进而利用有限元计算结果验证了卡具的周向与轴向密封的可行性。通过优化设计,新型对开式高压管道卡具减小了卡具变形量,提高了卡具周向与轴向密封的可靠性,具有广阔的应用前景。
Taking into account of the existing defects in clamps used for rush-repair of pipes, such as severe deformation, slow leakage plugging and poor result in leakage stoppling, the clamps have been optimized in terms of material, tool body, lug, bolt and sealing material and a rational layout of reinforcement structure and filling port has been proposed for improvement of the clamp rigidity based on relevant results of classic theories and studies. By use of software Pro/e, a 3D physical model has been established for the new high pressure clamp, a quantitative analysis has been made for clamp stress, strain and displacement, fia＇ther to verify the feasibility of clamp＇s circumferential and axial sealing by means of finite element calculation. As a result of optimized design of the new split-on high-pressure pipeline clamp, clamp deformation has been reduced and the reliability of clamp＇s circumferential and axial sealing has been enhanced, providing broad future for deployment and application. （10 Figures, 12 References）
