Experimental Research on Interactions of Slotted Parameters for Rotary Distributing Excitation Control Valves#br#

A rotary distributing excitation control valve was proposed. In order to determine the influences of spool slotted parameters and the interaction on the output pressure of excitation control valves, the output pressures of excitation control valves was simulated based on multi-reference systems sliding grid method by Fluent, and the simulated results were verified by experiments. A significant regression model of slotted parameters and output pressure was established by using quadratic regression orthogonal test method and central composite test method.Through the analysis of ANOVA （analysis of variance）, the significant difference and the response surface under the interaction of slotted parameters affecting the output pressure were obtained. The Influence trend for interaction of slotted parameters on the output pressures was discussed.The results show that in the test space, as the slot length, slot width and slot depth increase, the output pressures of excitation control valves increase by 8.3%, 25.1% and 22.3% respectively, the order of effective extent is width, depth and length. The interactions of slot width with slot length and depth have the most significant effect on the output pressures of excitation control valves.
