Disclosed is a balanced water-intake control valve, comprising an adjusting mechanism of water-level between two linkage rods. The adjusting mechanism includes a first pivot guide, a second pivot guide, a lead screw and an adjusting nut. The first pivot guide is pivoted at the first linkage rod for driving a valve rod. The second pivot guide is pivoted at the second linkage rod connecting to a float body. The first and second pivot guides are connected by the lead screw at opposite ends. At the middle of the lead screw, an adjusting nut is placed. By rotating the lead screw, the length between the first and second pivot guides can change. Therefore, the water-level upper limit can be adjusted by the user's demand after installing of the control valve.
