摘要
介绍了阀体镶轴套孔是带有硬度差及切削不连续的特殊结构,论述了孔的工艺加工试制过程,提出了结构优化的方案,保证了阀体与轴套装配后的轴套孔尺寸精度。
This paper introduces that the valve sleeve hole is of hardness difference and special structure of discontinuous cutting, discusses the processing technology production procedures of the hole, propo- ses structure optimizing scheme, ensures the inner hole size accuracy of valve body and collar sleeves after assembly.
