摘要
介绍了轴流式止回阀的用途和性能特点,对比分析了常规轴流式止回阀的结构特点,阐述了为实现CAP1400轴流式止回阀的阀位常开、在役试验、在役检测、经受反向流冲击等功能所作的结构改进。
The application and performance characteristics of axial flow check valve are introduced.The structural characteristics of conventional axial flow check valve are compared and analyzed.This paper describes the structural improvement of CAP1400 axial flow check valve for its functions of normal opening,in-service test,in-service inspection and adverse flow impact.
