The invention relates to a number lock balance valve, and belongs to the technical field of balance valves. The number lock balance valve comprises a valve deck mounted on a valve body, wherein a valve clack is mounted in the valve deck, a valve rod is mounted in the valve clack, a rotary table provided with a hand wheel is fixedly mounted at the outer end of the valve deck, the upper end of the valve rod penetrates through the rotary table to be connected with the hand wheel, and a locking device is arranged between the rotary table and the hand wheel. According to the number lock balance valve, the locking device is arranged between the rotary table and the hand wheel, so that the locking function after well adjustment of flow is improved greatly, higher requirements of a high-end user for flow adjustment are greatly met, the locking function is simple to operate, and use of the user is facilitated. By means of the locking structure, hydraulic balance among loops of a system can be realized, designed flow c
