An adjusting valve of the ventilation water tank comprises a front end tooth groove, a main body is a plate-shaped structure with a shaft and a valve tail end, and the circular plate-shaped structure with the shaft is matched with the cross section of a ventilation pipe in size. A ventilation pipe penetrates through the top of the water tank main body; a shell is fixed to one side face of the ventilation pipe, a front end tooth groove is formed in the shell, an adjusting handle is arranged outside the shell, and the adjusting handle is fixedly connected with the front end tooth groove. Bearing seats are fixed on the opposite side surfaces of the ventilation pipe, and are internally and rotatably connected with the valve tail end; a sliding groove is formed in the shell, a bolt is slidably connected into the sliding groove, and the front end of the bolt is inserted into the front end tooth groove to limit the rotation angle of the adjusting valve. A filter box is installed on the top of the ventilation pipe in a penetrating mode, an exhaust fan is arranged in the filter box, and a filter mechanism capable of being rapidly replaced is arranged above the exhaust fan. The ventilation requirements in different use scenes can be met by adjusting the rotating angle of the adjusting valve, the practicability and flexibility of ventilation of the water tank are improved, and the ventilation air volume can be accurately controlled.
