摘要(Abstract)：

空气阀作为输水系统中负压消除的有效设施,在管线充水、排水阶段也同样担负着重要的作用,但由于选型、布置等方面缺少系统性的指导,在实际工程中多按照经验进行选取,以致造成许多安全性事故的发生。综合国内外研究对空气阀的种类、主要功能以及维护等方面进行介绍,并主要针对空气阀在水锤防护方面的影响因素进行分析和讨论,指出了目前空气阀在设计、选用、布置等方面存在的问题,尤其是缺乏空气阀内部动态特性的研究,可为相关研究学者提供参考和帮助。
As an effective measure for elimination of negative pressure in the water supply system,the air valve also plays an important role in the pipeline filling and draining stages. However,due to the lack of systematic guidance in type selection and arrangement,etc.,the air valves are selected mostly according to experience in practical engineering,which even causes occurrence of a lot of safety accidents. In this paper,the types of air valves,main functions and maintenance,etc. of air valve are introduced by synthesizing researches at home and abroad,and analysis and discussion are carried out mainly on the influence factors of air valve in the water hammer protection,the current problems existing in design,selection and arrangement of air valves are pointed out,especially the lack of researches on the dynamic characteristics of air valves,which can provide reference and help for relevant researchers.
