| 摘 要： | 针对新型内置弹簧金属C形密封环在高压管道法兰密封上的应用条件，采用ANSYS有限元软件建立三维仿真模型，并通过相关实验验证本文理论模拟方法的可靠性；基于仿真结果分析了C形密封环压缩-回弹性能和密封环相关参数对密封性能的具体影响。结果表明：对于管道密封环，其压缩率、合金包覆层厚度、弹簧丝直径和弹簧匝外径分别在20%~25%、0.25~0.30 mm、0.60~0.70 mm和4.0~4.2 mm范围内时，密封环具有良好的密封性能。

| Abstract: | A three-dimensional simulation model of a new type of metal C-ring with a built-in spring for a high pressure pipeline flange seal under actual application conditions has been constructed using ANSYS finite element software,and the reliability of the simulation method was verified by experiment.The compression-recovery performance of the sealing ring is analyzed and the effects of some relevant parameters on its sealing performance are also discussed in detail.The results show that when the compression ratios,thickness of the covering layer,diameter of the spring wire and diameter of the spring are in the ranges 20％-25％,0.25-0.30 mm,0.60-0.70 mm and 4.0-4.2 mm,respectively,the sealing ring gives a good sealing performance. |
