SCIENTIFICALLY GROUNDED CRITERIA FOR THE SELECTION OF CONTROL VALVES IN THE TRANSPORTATION AND DISTRIBUTION OF PETROLEUM PRODUCTS

The article examines the issues related to the selection of control valves (flow-forming and flow-directing elements) used in the distribution of petroleum products from storage tanks and their transportation through pipelines. The research is based on the regularities associated with evaporation losses of petroleum products, gas phase formation, hydraulic flow regimes, and the Reynolds number. The efficiency of control valves is evaluated using graphical diagrams and tables.本文探讨了石油产品从储油罐配送并经管道输送过程中所使用的控制阀（flow-forming and flow-directing elements，流体成型与导流元件）的选型相关问题。本研究基于石油产品蒸发损耗、气相形成、水力流态以及雷诺数（Reynolds number）的相关规律展开。研究通过图表与表格对控制阀的效能进行了评估。
