缓闭式空气阀口径和孔口面积比对停泵水锤防护的影响
Non-slam Air-valve's Diameter and Area Ratio Impacted Pump-stop Water Hammer Protection
摘要
Abstract
In order to solve the problems about pipeline failure and pipeline fracture caused by using wrong type and diameter of air-valve in accident condition,Improved the mathematical model of conventional air-valve,got the mathematical model of non-slam air-valve,Accorded to the theory of water hammer and the method of characteristic,combined them with the volume of air inflow and the speed of water hammer,got a formula for the diameter of non-slam air-valve.using Hammer software for numerical simulation of southwest long distance and undulating water pipeline in pump-stop situation.The results show that:water hammer protection has a relationship with diameter and area ratio of non-slam air-valve,verified the formula is feasible.The results of research can provide reference for non-slam air-valve's diameter and area ratio selection in conveyance engineering.关键词
