Abstract：In order to provide a design basis for the structural parameters of the divertional on the rocking arm sprinklers, this paper described main factors exerting a influence, on structural parameters of divertional and gave correlations between the rotational inertia J and the structural parameter R1 of rocking arm , the rotational inertia J of the rocking arm and nozzle diameter d0 and the ratio between R1,R2,R3,R4 by means of regression analysis about structural parameters of the divertional (covering 14 types of sprinklers). Based on combination with the theoretical analysis, the paper led the formula for the ratio U/ω0 between the jet flow velocity and oscillating angular velocity of the rocking arm. The calculating method may be contributed to the design of the structural parameters of this kind of sprinklers ’ divertional.
