摘　　要：介绍了一种具有二级节流口的新型先导式海水液压定压输出减压阀。分析并建立了该阀的稳态数学模型,在数学模型基础上,对其中的次要参数进行合理地简化,进一步得到该阀的稳态响应特性。通过数值分析,得到部分结构参数对阀稳态性能的影响。分析结果不但表明该阀具有良好的稳态特性,也验证了分析过程中简化处理的合理性。A new kind of seawater hydraulic pilot-operated constant pressure pressure-reducing valve with a two-step throttle is introduced.Then the static mathematical model of the valve is established.Based on the model,the static characteristics of the valve are gained by simplifying some secondary parameters reasonably.By the meaning of numerical analysis,the influences of some major structural parameters on the static performance of the valve are obtained.The results not only show the valve has good static characteristics but also verify the reasonableness of the simplification.
