| 摘 要： | 运用CFD软件对某型号偏转板射流阀内部不同阀口参数组合下的压力特性进行数值计算和分析，得出偏转板射流阀输出压力特性随不同阀口结构参数组合的变化规律。计算发现： 供油压力为4 MPa 时，λ1≈0.6，1.5≤λ2≤2，1≤λ3≤1.5组合下偏转板射流阀输出压力增益较大，输出压力特性曲线与偏转板位移成线性关系，研究结果可为偏转板射流伺服阀的工程设计和优化提供理论依据与参考。

| Abstract: | The pressure characteristics of a certain type of deflector jet valve with different port parameters combination are calculated and analyzed by using CFD software in the paper,and the change law of output pressure characteristics with different structural parameters combination of valve port in deflector jet valve was obtained. Calculation results show that: when oil pressure is 4 MPa, λ1≈0.6， 1.5≤λ2≤2， 1≤λ3≤1.5, the deflector jet valve output pressure gain is larger, the output pressure characteristic curve is linear with the deflection plate displacement.The results can provide theoretical basis and reference for the engineering design and optimization of deflector jet servo valve. |
