| Abstract: | Based on the derivation of the parameters related to the gap between the nozzle and the flapper,this paper reveals the influence of the gap on the dynamic and static performance of the flapper servo valve,including the influence on the static loss flow,threshold,hysteresis and dynamic characteristics.Finally,it is verified by experiments,which provides theoretical guidance for the design and maintenance of this type valve. |
