摘要
核电站主蒸汽隔离阀技术要求严、安全系数高,是核电装备国产化进程中的重点攻关项目之一。某些核电站在运行过程中其主蒸汽隔离阀出现过气流诱发振动与噪声,最终导致阀门部件磨损的现象。本文通过数值方法对主蒸汽隔离阀内三维湍流流场进行模拟分析,研究找出产生振动与噪声的流场诱因。本工作的数值分析结果与现场的测量结果相符。
The main steam isolation valve（MSIV） in nuclear power station is one of the most important items of nuclear equipments in Localization Process project,which requires strict technical standard and high safety coefficient.During the operation of some nuclear power stations,MSIV gets the problem of vibration and noise due to airflow,which leads to the damage of valve accessory.In order to find the reason of vibration and noise,the method of numerical simulation to calculate the inner 3D on flow field of MSIV was used.The results of numerical analysis match with the on-site measurements.
