Zusammenfassung:	A device for controlling gas flow includes a motor, a valve body connected to the motor, a threaded sleeve configured to be driven by the motor to rotate, a threaded rod matched with the threaded sleeve on a first end of the threaded rod, a first guide sleeve, a compression spring sleeved on the threaded rod; and a valve plate connected to a second end of the threaded rod and configured to cover a vent valve hole. The second end of the threaded rod extends through the first guide sleeve and the first guide sleeve surrounds a part of the threaded rod in axial direction, preventing the threaded rod from rotating.
