油煤浆调节阀阀杆扭矩成因分析及结构优化

Torque causation analysis and structural optimization on oil-coal slurryvalve stem

用Solidworks建立油煤浆调节阀的三维实体模型,通过对阀杆机构的扭矩作用分析,应用CFX流体分析软件对流道内介质在不同压力下的流动进行仿真,研究调节阀扭矩产生的原因.以减小扭矩为优化目标,对调节阀阀芯及填料结构进行优化改进,为调节阀的优化设计提供参考方案.

Based on the 3D solid modeling via SolidWorksTM for oil - coal slurry valve, the torque effect on valve- stem mechanism is first analyzed. Then, the causation analysis is postulated using CFX method for flow simulation on internal media under different pressures. To reduce the torque, the regulator valve core and packing structure are improved to provide a reference to valve optimal design.
