Provided in this paper, using fluid dynamics analysis software CFX, the flow field within the valve cavity is analyzed and calculated. By changing the valve cover installation status and valve cavity dimensions, the flow field is calculated respectively. The influence of the two factors on air flow is summarized, which can be used to guide the design.%采用流体动力学分析软件CFX,对气阀腔内的流场情况进行分析计算.通过改变压阀罩安装状态和气阀腔尺寸分别进行计算,总结出这两种因素对气流流动的影响情况,从而指导设计工作.
