Numerical Simulation of Throttle Valves with Different Spool and Valve Body by Fluent

This paper analyzed the optimal structure of hydraulic throttle valve theoretically,and studied the flow field and pressure field of throttle valves with different structure combination of spool and valve body by Fluent.The results show:changing the structure of valve spool has more influence on the internal fluid flow of valve than changing the structure of valve seat;the fluid flow of the throttle valve with double-cone valve spool and single-cone valve seat is the most stable.
