Air valve and fan interlocking control system

The invention relates to the technical field of ventilation, and discloses an air valve and fan interlocking control system which comprises an air valve (20), a fan (21) and a power distribution control device (6) with a microcontroller (8), wherein the microcontroller (8) is in signal connection with the air valve (20) and the fan (21), and is configured to control the fan (21) to be started after the air valve (20) is opened, and/or control the air valve (20) to be closed after the fan (21) is stopped. The power distribution control device with the microcontroller is arranged, the power distribution control device can control the fan to be started after the air valve is opened and the air valve to be closed after the fan is stopped through the microcontroller, so that the linkage requirement of the air valve and the fan is met, electrical device configuration of an installation site is simplified, the complexity of power distribution wiring is reduced, and the production cost is reduced. 本发明涉及通风技术领域，公开了一种风阀
