长输管道泄压阀的应用及改进

Application and Improvement of Relief Valves over Long DistancePipeline

介绍了长输管道水击角式自力泄压阀的类型及工作原理。针对水击角式自力泄压阀在实际应用中因设计缺陷导致的配件多和安装作业难度大等问题,对其进行了优化改进。经输油生产运行实践表明,改进后的水击角式自力泄压阀具有较强安全可靠性,能有效防止水击现象,保证长输管道安全平稳运行。

The types and work principles of the angle self-contained relief valve of water hammer are introduced. As for the problems of excessive parts and difficult installation caused by design defects of this kind of relief valve,optimal improvement is made to it. The improved relief valve is provided with highly safety reliability for effectively protecting it from water hammer and ensuring the long distance pipeline operating stably.
