摘要
介绍了阀门内漏在线检测技术、内漏试验系统、内漏的声音检测和内漏的正确定性方法,分析了阀门内漏的声学特性,讨论了阀门种类、公称直径、进口压力、开启高度对声音强度的影响。
The testing technology online,the testing system,the sound detection,and the correct qualitative method of valve inner leakage were introduced. The acoustic properties of valve inner leakage were analyzed. The effect of valve type,nominal diameter,inlet pressure,open height on sound intensity was discussed.
