35孔流量调整器的设计与应用

Design and Application of 35-hole Flow Regulator

在气体封闭管道输送计量中,消除或最大程度地减少流态畸变的有效方法是在流量计上游安装流量调整器。在流量调整器与流量计之间需要一定长度的直管段,介绍了直管段长度的选择和实验方案,以达到最佳整流效果。性能优良的流量调整器可以改善进入流量计的流体流态,优化流动条件,提高流量计的测量准确度。

In the measurement of the closed gas pipeline, to eliminate or minimize the distortion of the flow state, the effective way is to install a flow regulator in upstream. There is a straight pipe between flow regulator and flow meter. The paper studies the choice of the length of straight pipe and experimental scheme, to achieve the best rectifying effect. Flow regulator with excellent performance can improve the flow state, optimize flow conditions, and improve flow measurement accuracy.
