摘　　要：煤液化过程中,煤浆的输送要求在高压、高流量下进行,煤浆对减压阀的破坏非常严重。用Fluent软件对187137-IP型减压阀进行了内部流场的数值模拟研究,并与试验相比较,找到了187137-IP型减压阀阀芯失效原因为煤浆冲刷磨损。在此基础上对减压阀的结构提出改进意见。The delivery of coal slurry requires high pressure and high flow capacity during the liquefying process of coal slurry. The damage of the spool by the flushing of the coal slurry is very severe . By means of numerical simulation of the valve＇ s inner flow field using Fluent software and comparing with the experiment, the failure mechanism of 187137-IP relief pressure valve spool was found out, and the suggestion for improving the structure of the valve base was presented.
