文章摘要: A new type pilot of zero steady-state error hydraulic overflow valve is designed in this paper, and the structure characteristics of the valve is introduced. In the partial hypothesis premise, a precise mathematical model of overflow valve is established. By using the actual parameters and universal numerical, the steady-state error of the zero steady-state error of water hydraulic overflow valve is explored. With the aid of Matlab / Simulink on the new valve structure for dynamic and static simulation analysis, the static and dynamic characteristics and stability of the valve are studied at the pressure of 31MPa working conditions. The simulation results indicate that, the valve has better dynamic and static characteristics, its response time reaches to 12sm, AFW reaches to 86Hz and phase bandwidth reaches to 87.6Hz.
