摘要/Abstract

摘要： 核电主蒸汽释放隔离阀(简称：释放隔离阀)是应用于第三代核反应堆的新型高端控制阀门，对于保障核电站二回路系统的安全和功能具有重要的作用。为了深入揭示其运行机理，论文从流-固-热多物理场耦合建模出发，结合样机试验，对释放隔离阀内部的流场特性、启闭动作特性以及关键设计参数开展了专门的研究。揭示了多场耦合作用下释放隔离阀内部流场的产生与演化机制、阀芯驱动力的形成与变化机理，并探究了关键设计参数对阀门动作性能的影响规律。论文的研究方法与结论不仅有助于对释放隔离阀动作特性的深入理解，还对其精细化设计与综合性能提升具有参考价值，同时对打破欧美国家在此领域的技术垄断，实现中国核电“走出去”战略具有促进作用。

Abstract: Nuclear main steam relief isolation valve(MSRIV) is one type of high-end control valve, which plays an important role in ensuring the safety and function of the secondary circuit system of nuclear power plants. To reveal its operation mechanism in depth, this paper starts from fluid-structure-thermal multi-physics coupling modeling, combined with prototype experiments, and conducts a special study on the flow fields, action characteristics and key design parameters of the MSRIV. The generation and evolution mechanism of the internal flow field and the change mechanism of the driving force under the multi-field coupling are revealed, thereby the influence of key design parameters on the valve action performance is explored. The research methods and conclusions of this paper are not only helpful to the in-depth understanding of the operating characteristics of the MSRIV, but also have reference value for its design and performance improvement, and also the “going out” strategy of China.

Key words: MSRIV, open-reclosure characteristics, numerical modeling, transient simulation, parameter analysis
