摘要
概述油气管道管内封堵器及密封结构的发展情况。介绍管内封堵器密封系统的构造及工作原理,对封堵器密封结构的研究进展进行综合评述。讨论了封堵器密封结构中各结构参数对密封可靠性的影响。从国际先进水平的管内封堵器密封结构的发展趋势和可靠性要求,对未来封堵器密封结构的技术发展远景进行了展望。对于国内开展同类技术研究具有深刻的指导意义。
In the article, development of the occluder and sealing structure of oil and gas pipeline is outlined. The structureand working principle of occluder sealing system are introduced, and comprehensive review of the research progress on thesealing structure is also conducted. The effect of structural parameters on the sealing reliability in the sealing structure is dis-cussed. According to the development trend and the reliability requirements of the occluder sealing structure in the internation-al advanced level, the future technical development prospect of the occluder seal structure was discussed. Thus it has a pro-found significance for the domestic research on similar technology.
