Abstract

The utility model relates to the technical field of valves, and discloses an automatic variable air volume ventilation regulating valve. The ventilation regulating valve comprises a shell, blades, an electric actuator, a sensor and a controller, the blades are rotatably arranged on the shell through a rotating shaft, the electric actuator is arranged on the shell and is in transmission connection with the rotating shaft, the sensor and the controller are arranged on the shell, and the sensor and the electric actuator are respectively and electrically connected with the controller. According to the ventilation regulating valve, the sensor detects environment data of indoor space, the controller calculates the needed air supply amount according to the environment data and sends corresponding control signals to the electric actuator, the opening amplitude of the blades is controlled, the air outlet amount is controlled and regulated, the air supply amount is automatically regulated and accurately controlled according to actual requirements, and the ventilation regulating valve is simple in structure and convenient to use. The situation that the air volume is too large or too small frequently occurring in a constant air volume system is avoided, the energy consumption of the system is reduced, energy conservation and consumption reduction are achieved, and resource waste is reduced.
