摘要
阐述了轴流式止回阀的流阻性能测试原理、检测装置设计及检验与分析,探讨了利用压差-流速函数关系,以流速为依据选取测试点,并提出了不同公称尺寸轴流式止回阀的推荐测试点选取方法。
Testing principle of flow resistance performances, design of testing equipment, inspection and analysis of axial check valve are introduced, and testing points selection method based on flow rate for using the function of pressure drop and flow rate is discussed, while recommended flow rate ranges for the testing of those samples with different nominal size are put forward.
