摘要
本文对在燃气输配工程中有广泛应用的球形管接水力特性进行了实验分析.由于球形管接结构复杂,因此与普通三通的阻力系数有很大差异,在管网设计中必须考虑此变化.本文给出了在不同分流比工况下的阻力系数,并就管接的水力特性进行了探讨.
The hydraulic resistance of a new kind of wye has been investigated by means of experimental method. Owing to the complex construction of the wye, the pressure loss coefficients are much different from that of common wyes, so that the difference must be considered in the pipe network calculation. The coefficients of fluid resistance have been presented in different ratios of flow rates.
