Abstract

Because of complexity of the inner structure of hyddraulic poppet valve and uncertainty of the affection of its performance led by the parameter,the Computational Fluid Dynamics method was adopted to analyze the different inner structure,and the valve of discharge coefficient and steady flow force of hydraulic poppet valve in different uncork was gained.The results show that when the cone is 90 degree and circumference diameter is 16mm or 16.5mm have the optimization design of this valves.
