摘　　要：设计了进口接管７孔型挡板和出口接管３孔锥形挡板，按“变体”相似理论设计水力模型和模拟试验体，以水为工作介质进行了冷态模拟试验，获得了１０条局部阻力系数与雷诺数的关系曲线。据试验结果进行的计算和分析表明，与５５／１９Ｂ型蒸汽发生器相比，设置７孔型进口挡板和三孔锥形出口挡板使ＡＣ６００蒸汽发生器一次侧的压降增大约１４％。Seven holes type bracket plate at the inlet nozzle and three holes taper bracket plate at outlet nozzle are designed.According to“local form and structure change” simular theory,hydraulic models and simulators for the simulative experiments are designed.Taking water as the medium,the simulative experiments have been completed at the room temperature.The ζ Re curves (here,ζ is the local pressure loss coefficient at the nozzles after the bracket plates are installed and Re is Reynolds number)have been got.Based on the experimental results,the computation and the analysis have been shown that.If the bracket plates are used in the steam generator(SG)of AC600 PWR,the pressure drop of primary side in the SG is about 14 percent higher than that of the 55/19 B stype SG.
