摘　　要：核电站汽轮机旁路调节阀,用于汽轮机旁路系统中,为反应堆提供一个“人工负荷”,避免核蒸汽供应系统(NSSS)中温度和压力超过保护阈值,维持一回路与二回路的功率平衡。通过综述汽轮机旁路调节阀的研发实践,结合样机热态全流量湿蒸汽试验的状态和数据,验证了阀门设计的合理性,为该类调节阀的自主化设计和热态功能试验提供研究思路和借鉴经验。The turbine bypass control valve of the nuclear power plant is used in the turbine bypass system to provide an"artificial load"for the reactor,to prevent the temperature and pressure in the nuclear steam supply system(NSSS)from exceeding the protection threshold,and to maintain the power of the primary circuit and the secondary circuit balance.This paper reviews the research and development practice of turbine bypass control valve,combined with the status and data of the prototype thermal full flow wet steam test,to verify the rationality of the valve design,and to provide research ideas and experience for the independent design and thermal function test of this type control valve.
