The invention provides a fluid power optimizing method for a hydraulic valve and belongs to the technical field of structure optimization of hydraulic valves. By the adoption of the fluid power optimizing method for the hydraulic valve, the problem that in the prior art, since a large quantity of manual calculation and screening is needed for structure optimization design of a hydraulic valve to compensate for the influence of fluid power, the designing efficiency is low is solved. The fluid power optimizing method for the hydraulic valve comprises the steps that structure parameters which can be optimized are determined; structure parameters to be optimized are selected, and the value range of the structure parameters to be optimized is determined; a three-dimensional valve flow channel model of the hydraulic valve is established; an intra-valve flow field in the hydraulic valve is calculated; fluid power borne by a valve element of the hydraulic valve is extracted; an optimized objective function is establi
