由高桥化工厂、石化部化工设计院、石化部炼油设计院、石化部洛阳石油设计研究院、安徽石油化工设计院、上海工业自动化仪表研究所共六个单位组成的调节阀流量特性选择试验研究工作组,自七五年八月五日至九月二十五日在上海自动化仪表所进行了第一阶段的试验研究工作。并汇编了“调节阀流量特性选择试验研究报告(一)”,本文是摘自其中的第五部分。该部分对调节阀口径计算中,C值圆整的倍数m与那些因素有关,以及如何选择合适的C值提出了一些意见。登载于这里作为问题提出,供同志们讨论,希望读者提出宝贵意见。 From the Takahashi Chemical Plant, Chemical Design Institute of Petrochemical Industry, Petrochemical Refinery Design Institute, Ministry of Petrochemical Design and Research Institute of Petroleum in Luoyang, Anhui Petrochemical Design Institute, Shanghai Institute of Industrial Automation Instrumentation composed of six units of the control valve flow characteristics of choice test Research Working Group, from August 5, 1975 to September 25 at the Shanghai Automation Instrumentation conducted the first phase of the pilot study. And compiled a “valve flow characteristics of selected test research report (a),” This article is excerpted from the fifth part. This part of the calculation of the caliber of the control valve, the C value of the round m times those factors, and how to choose the appropriate C value made some comments. It is posted here as a question for discussion by the gay people and I hope readers will come up with valuable suggestions.
