摘　　要：介绍了输水管线中空气的来源、危害以及安装空气阀的必要性,对长距离输水管线中空气阀的设置进行了探讨,并根据国内外对有压输水管道气水两相流的最新理论研究和实验成果,对进排气阀的结构原理进行分析,论述了长距离有压输水管路进排气阀选型设计的相关问题。Based on an introduction of the sources and harms of air in the water delivery pipeline as well as the necessity of air valve, the author probed into the arrangement of air valves along the long-distance water delivery pipeline. In accordance the latest domestic and overseas theory research and testing achievements of air-water two-phase flow in the long-distance pressure delivery pipeline, the author also analyzed the structure and theory of air intake/relief valve and discussed the selection and design of air intake/relief valves for the long-distance pressure delivery pipeline.
