供水管网排气阀检测与分析方法研究

Study on air-vent valve detection and analysis in water supply pipe network

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 , comparing 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 .
