Abstract

The invention provides an air valve. The air valve comprises a shell, a valve shaft and a valve plate, wherein the shell defines a channel having an inlet and an outlet, and the channel has a channel length direction, a channel width direction, and a channel height direction; the valve shaft is arranged in the channel and is arranged in the width direction of the channel; the valve plate is arranged on the valve shaft and provided with an opening position and a closing position, and the valve plate is configured to be capable of rotating between the opening position and the closing position around the axis of the valve shaft; when the valve plate is located at the opening position, the valve plate extends roughly in the length direction of the channel, when the valve plate is located at the closing position, the valve plate extends at an angle to the length direction of the channel, and the valve plate is provided with a first end and a second end; and at least one of the first end and the second end of the valve plate is provided with a sealing piece, and the sealing piece is configured to extend in the length direction of the channel when the valve plate is located at the opening position. The air valve has good sealing performance at the closing position and is small in air resistance at the opening position.

Description

technical field [0001] The present application relates to the field of ventilation, in particular to dampers. Background technique [0002] A traditional air valve includes a rotating shaft and a valve plate arranged on it. The valve plate has an open position and a closed position. However, conventional dampers are less airtight in the closed position. Therefore, there is a need for a damper that is more airtight in the closed position. Contents of the invention [0003] In order to achieve the above purpose, the present application provides a damper, which includes a housing, a valve shaft and a valve plate. The housing defines a channel having an inlet and an outlet, the channel having a channel length direction from the inlet to the outlet, a channel width direction transverse to the channel length direction, and a channel width direction transverse to the channel Channel height direction for length direction and channel width direction. The valve shaft is arrange...
