供水管网排气阀检测与分析方法研究

摘要

对郑州市供水管网运行中的排气阀进行了分类，确定出了7种类型排气阀，并选取了阀体进行进排气检测，对比优选各种排气阀的进排气性能，在此基础上对管网中使用的阀体进行了现场监测，考察排气阀运行效果，统计分析了郑州市排气阀现状，为郑州市排气阀的设置和运行管理提出了建议。%The project classified the air -vent valve of water supply pipe network in Zheng-zhou City, identified seven types, and select the intake and exhaust valve for testing , compa-ring various preferred intake and exhaust vent performance , on the basis using a air -vent valve on-site monitoring visits , the statistical analysis of the status , recommendations for air-vent valve ’ s setting and operation management was put forward .
