Summary:The invention relates to a control logic optimization method and system for a hydraulic control butterfly valve, and the method comprises the steps: obtaining the water pump opening degree of each circulating water pump in a DCS control system and the water pump state corresponding to each water pump opening degree, and carrying out the linkage adjustment of the butterfly valve opening degree of the current hydraulic control butterfly valve according to the water pump opening degree and the water pump state, the circulating water flow direction under the butterfly valve opening degree is obtained, the water pump opening and closing sequence of a DCS control system is adjusted according to the circulating water flow direction and the butterfly valve opening degree feedback, and the butterfly valve opening and closing sequence of each water pump associated butterfly valve is synchronously adjusted according to the water pump opening and closing sequence. And calculating the valve opening delay time between each
