四堡污水处理厂排污管喷口研究

Development of New Spray Nozzle of sewage Pipe in Hangzhou sibao Sewage Treatment Plant

介绍了四堡污水处理厂排污入江管工程中应用的新型三口单向阀型自动喷口结构。叙述了排污量、开启度、喷口流速、阻力系数等水力特性。对喷口的安装施工以及喷口流速、开启度、喷口冲坑形状的现场检测也作了说明。

his paper presents a new tyep of spray nozzles with 3 openings, which used in Hangzhou Sibao Sewage Treatmant Plant.The hydraulic characteristies,as such as the rate of opening angle. nozzle、velocity and coefficient of resistance and so on,have been descreibed. Finally at the method of crection of the Spray nozzle,field measurement of flow velocity in nozzle,opening angle and the form of scouring of the river bed are described
