大型水泵水轮机球阀的制造是水轮机关键部件制造技术的瓶颈问题,多年来一直是国内外大型水电公司研究的主要课题。本文以黑麋峰球阀制造为例,分析了整体式球阀焊接结构的特点、焊接制造的难点、机械加工制造及装配的难点。通过该球阀的成功制造,探索出了一套完整、合理、经济的焊接、机加工制造工艺方法,为相同结构球阀的制造打下了坚实的工艺技术基础。
Large-scale pump turbine valve manufacturing is the key component of turbine manufacturing technology bottleneck, over the years has been the major issue of large-scale hydropower companies at home and abroad. In this paper, black elk peak valve manufacturing as an example, analysis of the characteristics of the integral ball valve welding structure, the difficulty of manufacturing welding, machining manufacturing and assembly difficulties. Through the successful manufacture of the ball valve, a complete, reasonable and economical welding and machining manufacturing process method has been explored, laying a solid foundation of technology for the manufacture of the same structural ball valve.
