According to the conventional equipment performance inspection plan and engineering actual There is a big difference between them, and the actual application of the equipment in engineering is unknown. Therefore, during the equipment development stage, 1:1 calibration test is carried out according to the actual engineering, which can not only test the comprehensive performance of the equipment well, but also Anticipated risks that may occur in engineering applications can be identified in advance.
2、工程试验风险提前辨识：爆破阀流阻模拟件在国内属于首次设计、研制、加工及测试，其在工程实际应用中可能产生的非预期或预期风险如未经实际测试难以准确判断，因此在爆破阀流阻模拟件标定测试期间，使用与工程系统管道布置结构相同尺寸的1:1标定配管、1：1的配管结构、1：1的管件及管道设备进行爆破阀流阻模拟件标定测试，对模拟件应用于工程实际期间存在的风险及不确定性问题提前辨识，提高工程系统调试试验期间测量数据的可信度，以便于对系统核安全相关功能进行有效验证。2. Early identification of engineering test risks: The blasting valve flow resistance simulation is designed, developed, processed and tested for the first time in China. Unexpected or expected risks that may arise in practical engineering applications are difficult to accurately judge without actual testing. Therefore During the calibration test of the blasting valve flow resistance simulation part, use 1:1 calibration piping, 1:1 piping structure, 1:1 pipe fittings and pipeline equipment with the same size as the engineering system pipeline layout structure for calibration of the blasting valve flow resistance simulation part Test, identify risks and uncertainties in advance during the application of simulation parts to actual projects, and improve the credibility of measurement data during engineering system debugging tests, so as to effectively verify the system's nuclear safety-related functions.
3、积累研制成果数据基础：爆破阀流阻模拟件在国内属于首次研制，且属于非标设备，设备研制并无成熟经验和数据作为支撑，爆破阀流阻模拟件的设计结构、参数配置等均属于自主化原创，模拟件研制成果与设计预期数据的符合性必须通过实际测试试验进行检验，按照工程实际进行1：1标定即是通过试验对模拟件应用于工程实际之前的测量性能进行检测，相关数据可直接指导其他结构的爆破阀流阻模拟件的设计研发。因此实施1:1标定测试对工程及其他规格型号的爆破阀流阻模拟件的设计研制提供可参考的数据输入，奠定CAP系列核电厂爆破阀流阻模拟件国产化研制的数据基础。3. Accumulated research and development results data basis: The blasting valve flow resistance simulation is developed for the first time in China and is a non-standard equipment. There is no mature experience and data to support the equipment development. The design structure and parameter configuration of the blasting valve flow resistance simulation, etc. All are independent original creations. The conformity of the development results of the simulation parts with the expected design data must be verified through actual testing. The 1:1 calibration according to the actual project is to test the measurement performance of the simulation part before it is applied to the actual project. , the relevant data can directly guide the design and development of flow resistance simulation parts of blasting valves of other structures. Therefore, the implementation of 1:1 calibration test provides reference data input for the design and development of blasting valve flow resistance simulation parts for engineering and other specifications and models, and lays the data foundation for the domestic development of blasting valve flow resistance simulation parts for CAP series nuclear power plants.
综上，按照工程实际系统管道布置配置1:1的管道结构、尺寸、管件的爆破阀流阻模拟件标定工装，首先实现高压爆破阀流阻模拟件在应用于工程系统调试前性能测试，通过该标定工装实现高压爆破阀流阻模拟件的在工程实际应用中的真实精度准确测量、实现爆破阀流阻模拟件本体流阻的准确计算分析、实现爆破阀流阻模拟件测量能力验证。In summary, according to the actual system pipeline layout of the project, the blasting valve flow resistance simulation part calibration tool is configured with a 1:1 pipeline structure, size, and pipe fittings. First, the performance test of the high-pressure blasting valve flow resistance simulation part is implemented before being used in engineering system debugging. It passes This calibration tool realizes the true and accurate measurement of high-pressure blasting valve flow resistance simulation parts in practical engineering applications, enables accurate calculation and analysis of the flow resistance of the blasting valve flow resistance simulation parts, and enables verification of the measurement capabilities of the blasting valve flow resistance simulation parts.
