Therefore, a plurality of gas burners are arranged in the pizza oven. However, a plurality of gas burners are controlled by one control valve, which easily causes uneven gas supply to the plurality of gas burners, resulting in insufficient gas combustion and unable to improve the cooking efficiency of the pizza oven. But when using a plurality of control valves to control a plurality of gas burners, the number of knobs of the control valves corresponding to the pizza oven is large, which is not beautiful and has poor flexibility and practicability in use.
