摘　　要：插装阀在冶金装备中有着广泛的应用,本文建立了插装式顺序阀的数学模型,对插装式顺序阀在出口突然失去载荷情况下进口压力恢复过程进行了仿真分析,仿真与实验结果吻合,验证了数学模型,介绍了阻尼孔直径、弹簧刚度、进口流量等变化对进口压力恢复特性影响的实验结果。Cartridge valve has been widely taken for metallurgical equipments. The paper shows the establishment of mathematical model of cartridge - type sequence valve and the simulation analysis made during the valve inlet pressure recovery under the condition that the load of the valve at outlet lost suddenly. The simulation resuits prove to be in accordance with the experimental results, which verify the mathematical model. Experiments were carried out to check the influence of the change of parameters such as orifice diameter, spring stiffness and inlet flow rate upon the inlet pressure recovery.
