介绍了电磁阀的工作原理和分类,对电磁阀产品主要的优缺点及适用性进行了阐述,并对电磁阀在我国核电厂的应用情况以及应用前景进行了说明和分析。针对核级电磁阀的国产化情况,对某电磁阀有限责任公司取得核3级电磁阀民用核安全设备设计和制造许可证所制作模拟件的相关情况进行了详细的描述,重点介绍了模拟件的结构特点、工作原理、执行标准、主要工艺及工艺评定、技术指标、定试验等方面的内容,该模拟件对于核3级电磁阀具有较好的代表性。基于当前的情况,对核级电磁阀后续国产化的进展及前景进行了展望,并对各相关单位在全面推进电磁阀国产化过程中需发挥的作用提出了建议。
The working principle and classification of the solenoid valve are introduced. The main advantages, disadvantages and applicability of the solenoid valve are expounded. The application and prospect of the solenoid valve in the nuclear power plant in China are also described and analyzed. In view of the localization of nuclear-level solenoid valves, the author gives a detailed description of the relevant conditions of the simulation parts produced by the design, manufacture and manufacture of the nuclear three-stage solenoid valve civil nuclear safety equipment for a solenoid valve limited liability company. The simulation part The structure, working principle, execution standard, main process and process evaluation, technical index, test and so on. The simulation part has good representation for the nuclear three-stage solenoid valve. Based on the current situation, the prospect and prospect of the follow-up localization of nuclear solenoid valve are prospected, and suggestions are put forward for the relevant units to play an integral role in the localization of solenoid valves.
