均匀坡下变径管道的定型设计──再论特征点定位法设计变径管道

Pattern design for tapered pipeline on uniform slope

为确保均匀坡下多孔变径管道的压力均衡，本文从分析等比降点存在条件入手，揭示了各变径管段的管径和变径点位置与管坡、出水孔设计流量之间的内在联系，提出简便易行的解析方法。设计效果令人满意：压力偏差低，均匀度高，便于定型设计。

To ensure the Pressure et1ualizahon of tapered pipeline with many outlet on the uniform slope, this paper anasyzes the existing condition of equal slope point, reveals the inner relationship between diameter of each pipe section, position of changing point and pire slope and design flow rate of outlet and presents a simple analylical method. this method usel to design proves satisfactory low pressure deviation, high uniformity and easy to get a pattern design.
