摘　　要：介绍了天然气管道输送系统中承担启闭和调节功能阀门出现外漏的原因及对环境的影响。分析了管线阀门外漏失效模式及泄漏造成的危害,讨论了管线阀门泄漏的检测技术现状,设计了全焊接球阀阀体水压爆破试验及监测程序,并通过应变片监测得出阀门极限承载的能力,提出了天然气管道输送系统阀门监测的技术思路。The disposable clean energy natural gas is mainly transported to the end user through the pipeline system.The valve in the pipeline system mainly undertakes the function of opening and closing.The leakage of valves will lead to the discharge of natural gas to the external environment.In this paper,the failure mode of pipeline valve leakage and its influence are analyzed.The hydraulic blasting test of the valve body is designed and the ultimate bearing capacity of the valve is monitored by strain gauge.
