摘  要:用于化工行业的两通旋塞阀壳,材质为锡青铜ZCuSn10Zn2,阀壳结构较为复杂,且要承受水压试验。分析了锡青铜的铸造特性,针对两通旋塞阀壳的结构,分析了其易产生的缩松、缩裂铸造缺陷,对两种旋塞阀壳的铸造工艺进行了深入的探讨。采用设计的铸造工艺,生产出多批质量良好的旋塞阀壳铸件,将泵漏率控制在较低的水平,满足了批量生产的需要。The two-way cock valve shell used for chemical industry is made of tin bronze ZCuSn10Zn2.The shell structure is rather complicated,and it must bear the pump pressure test.In this paper,the casting characteristics of tin bronze were analyzed.In view of the structure of the two ways of the cock valve shell,the defects of dispersed shrinkage and shrinkage crack of casting were analyzed,and the casting process of the the two plug valve shells was deeply discussed.According to the designed casting process,several batches of castings with good quality were produced,and the leakage rate of the pumps was controlled at a lower level to meet the needs of mass production.
