Large Plunger Control Valve Model Test of Water Diversion Project
At present,there are relatively few model tests conducted on large-diameter plunger regulating valves in China,DN2400 electric plunger control valve has been used to regulate the flow of water diversion system in Yunnan Dali Ludila Project.According to the DN500 large-diameter plunger regulating,model test was carried out based on the appli-cation requirements of the prototype valve.The required flow rate without head loss was calculated,The parameters of the test bench water pump required for the full test stroke was obtained.Test requirements was met through installing two types of pumps on the test bench.In addition to the valve flow characteristic test,the valve cavitation performance was tested by judging the sudden change of the monitoring value of noise and vibration by external senses.The test re-sults show that the flow coefficient,flow resistance coefficient,flow capacity,and cavitation performance all meet the en-gineering design requirements.
