介绍了压水堆核电站蒸汽发生器蒸汽限流器的一种改进设计。在保持相同喉部总流通面积的条件下,通过试验证明,改进后的19个文丘里管的蒸汽限流器结构的压力损失比传统的7个文丘里管的明显减小,并验证了蒸汽限流器的压力损失计算方法。
An improved design of steam restrictor for PWR steam generator is introduced. The experimental results show that the pressure loss of the steam restrictor structure of 19 improved Venturi tubes is significantly reduced compared with that of the conventional 7 Venturi tubes and it is verified that the steam Calculation method of pressure loss of restrictor.
