The invention provides a float type water control valve. The float type water control valve comprises a valve cover, a valve bottom and a connecting core tube. The valve cover is provided with a fluidinlet. The valve bottom is provided with a fluid outlet, and the valve cover is connected with the valve bottom. The connecting core tube is installed between the valve cover and the valve bottom, and a flow passage is enclosed between the outer wall surface of the connecting core tube and the inner wall surface of the valve bottom. The fluid inlet communicates with the fluid outlet through the connecting core tube and the flow passage, and the flow passage area of the fluid inlet is not less than the flow passage area of the connecting core tube. The flow passage contains a float internally,and the float blocks the flow passage or conducts the flow passage under the action of fluid pressure. The float type water control valve optimizes the fluid passage structure and the fluid flow pathby additionally arranging
