Comparative Analysis of Pressurizer Proportional Spray Control Valve for PWR Nuclear Power PlantEn

  • 摘要:
      目的  稳压器比例喷雾阀是压水堆核电机组的关键阀门之一,是电站系统中唯一的核安全1级控制阀,掌握该阀门的技术特点对于工程实践和该阀门的自主化研发具有指导意义。
      方法  基于国内压水堆核电机组所用的两种典型结构——气动V型球芯式比例喷雾阀和电磁驱动角式比例喷雾阀,从结构设计、工作原理及运行维护等方面进行对比分析。
      结果  经过分析得出,两种结构型式的比例喷雾阀适用的技术路线不同,但均可实现核电站稳压器系统所需的喷淋控制功能,用户可根据核电厂的技术路线和具体需求选择相对适宜的产品。
      结论  但在未来新建核电市场中,电磁驱动型比例喷雾阀预计将有较广阔的应用前景。
    Abstract:
      Introduction  The pressurizer proportional spray control valve is one of the key valves for PWR nuclear power plant and it is the only level 1 nuclear safety control valve in power station system. Mastering the technical characteristics of the valve has very important guiding significance for engineering and domestic research for the valve.
      Method  Based on two typical structures used in domestic PWR nuclear power units - pneumatic V-ball proportional spray valve and solenoid angular proportional spray valve, this paper compared and analyzed them from structural design, working principle, operation and maintenance.
      Result  Through analysis, it was concluded that the two types of proportional spray valves have different technical routes, but both can realize the spray control function required by the pressurizer system of nuclear power plant. Users can choose relatively suitable products according to the technical route and specific needs of nuclear power plant.
      Conclusion  However, in the new nuclear power market in the future, the solenoid angle proportional spray valve was expected to have a broad application prospect.
