摘要
本文介绍了机械密封冲洗用限流阀的性能试验结果，推荐了平头阀芯顺流直角阀的３种规格，以满足有关石油化工用泵机械密封对冲洗量的不同要求。通过用水、煤油和机油等３种介质进行试验，得出了近似计算用的ｈ－Ａ－αＡ曲线，以用来确定限流阀的流量系数α。
he performance test result of control valves for flushof mechanical seals was presented. three sizes of down-strearn rightangle valves with flathead valve cores wererecommended to meet the needs of vartous flushes of me-chanical scals for petrochemical pumps. The h-A-aA curvesfor approximate calculation was derived to determine flowcoefficient a of control valves.
