【摘要】 以π桥液阻网络理论为指导，研制了Ｇ型π桥溢流阀，对其稳态和动态特性进行了试验研究，研究表明，改变Ｇ型π桥溢流阀先导回路的液阻参数，可使该阀的稳态调压偏差△ｐ为正、为零，也可以为较小的负值。在△ｐ为正和零时，该阀具有良好的动态特性。当△ｐ从零向负的方向增加时，其动态特性逐步变差并很快趋向不稳定。更多还原

【Abstract】 The relief valve with C - TC bridge hydraulic resistances pilot circuit was designed in terms of n bridge hydraulic resistances network theory, the static and dynamic characteristics were gained by experiment. The researches showed that the static pressure override Ap can be positive or zero value, and can be also small negative value in terms of pilot hydraulic resistances network parameters.更多还原
