摘要
在长距离供水工程中,空气阀是重要的水锤防护措施。以水锤分析为基础,构建了空气阀的数学模型,并结合工程实例,通过数值模拟仿真对空气阀在事故停泵工况下的水力过渡过程进行了计算分析。结果表明:合理设置空气阀,可有效控制沿线负压在管道承受标准之内,保证长距离供水工程的安全稳定运行。
In the case of long distance water transportation project, air valve is one of the important measures for water hammer prevention. The pa- per built the mathematical model for air valve on the basis of water hammer analysis, calculated and analyzed water power transition process of air valve under the event of pump-stopping through data simulation and provided guidance on ensuring smooth implementation of long distance water transportation projects.
