提出了一种先导回路为G型π桥液阻网络的减压阀新结构，对该阀的出口压力流量特性进行了仿真研究，分析了该阀先导回路有关参数的设计方法．该阀的压力流量特性根据先导回路液阻参数的不同设计，可以呈现3种形式：（1）减压阀出口压力随减压阀口流量增加而下降；（2）减压阀出口压力保持恒值，不随减压阀。流量的增减而变化；（3）减压阀出。压力随减压阀。流量增加反而上升．而普通先导式减压阀只具有一种特性，即随着流量的增加，其出口压力下降．图4，表1，参4
A new type of pressure relief valve with pilot circuit as G-type π-bridge liquid-resistance network was proposed. The outlet pressure-flow characteristics of the valve were simulated and the design method of the pilot-loop related parameters was analyzed. The valve pressure flow characteristics of the pilot circuit according to different parameters of the hydraulic resistance design, can be presented in three forms: (1) the outlet pressure relief valve outlet pressure decreases with the increase; (2) the outlet pressure relief valve to maintain constant Value, not with the pressure reducing valve. Flow changes and changes; (3) pressure relief valve out. Pressure with pressure reducing valve. Instead, the increase in traffic. Ordinary pilot-operated pressure reducing valve only has one characteristic, that is, as the flow rate increases, the outlet pressure drops. Figure 4, Table 1, reference 4
