利用途泄流量和输转流量确定天然气分配管道计算流量的研究

Research on Determining the Calculating Flow in Distribution Pipe of Natural Gas Based on the Shunting Flow and the Conveying Flow

在城市天然气管道的输送中,管道建筑用户相连,中途有流量分出,从途泄流量和输转流量的角度研究,利用计算公式来计算管段的计算流量,确定其压力降,并进行了举例说明,为输气管道的设计工作提供了参考。

In the conveying of natural gas of the city,the pipe connects with users and the flow shunts in the halfway.In this paper,according to the research on the shunting flow and the conveying flow,the calculating flow in pipeline was calculated by formula,and its pressure drop was gained,which can provide the reference for design of the gas transmission pipeline.
