摘要
阀芯卡紧是滑阀常见的故障,泄漏量过大也会对滑阀的工作性能产生影响.合理设计阀芯阀体的配合间隙,在阀芯上开设适当数量的均压槽,可以有效避免阀芯产生卡紧,同时获得较小的泄漏量.文章运用Fluent软件对60mm通径滑阀的缝隙流场进行仿真,结合试验研究,分析了均压槽对滑阀径向不平衡力和泄漏量的影响,评估了滑阀间隙密封结构,可为类似大通径滑阀的设计研发提供参考.
Valve element jamming is a common accident of slide valve, large leakage will also affect the function of valve. Rational design of the structure between valve element and valve body could prevent jamming and decrease leakage. The method of digging grooves on valve element is always used to prevent jamming. This paper numerically simulated the flow field in gap of 60mm diameter slide valve with the software Fluent. Then analyzed the influence of groove on unbalanced radial force and leakage by experimental research, to evaluate the gap structure of slide valve, and establish the technical basis for the design of similar large diameter slide valve.
