摘要
对立式升降式止回阀流道型线进行优化设计,采用Granville双参数平方多项式回转体流线型对阀瓣型线进行设计,选用Granville尾部型线对导流体型线进行设计.通过解析计算法、数值模拟法和试验验证对优化设计的新流道进行流阻分析,结果表明:新流道的流阻系数比原有流道下降约47%,且压力分布均匀、梯度小,具有优良的流场特性.
Lines plans of flow channel of vertical lift check valve were optimal designed. The lines plan of disc was designed on the basis of Granville double parameters square polynomial. The lines plan of guide shell was designed on the basis of Granville tail curve. According to the analysis of new flow channel by analysis method,numerical simulation and experimental verification,flow resistance coefficient of new flow channel was lower than before by about 47% and pressure distribution was uniform and gradient was tiny as well. It had good channel feature.
