输水管道工程排气阀选型设计探讨

在长距离、大直径输水管道工程中,排气阀的合理设置对工程安全起着至关重要的作用。所以,工程设计人员对排气阀的选择和布置也日渐重视。本文通过对有压输水管道系统中排气阀特性、管内气体的运动和对系统的危害进行研究,提出了排气阀选型设计的方法和应注意的问题,可供工程技术人员在供水管道工程设计中借鉴。

Discussion on the design for selecting the exhaust valve of Aqueduct project

The reasonable setup for the exhaust valve plays a vital role for the safety in the long-distance,large-diameter aqueduct project;therefore,the engineering designers are gradually recognizing their selection and layout.This paper researches the exhaust valve characteristics,the movement of gas and its hazards in the aqueduct system pressure,and put forward the approaches and attention problems in the design and provides the reference for water supply pipeline design.
