Air valve device

Abstract

The invention relates to an air valve device. The air valve device is arranged in a ventilation pipeline, and is used for adjusting the sizes of the air volume and the air speed of the air entering an air inlet which is arranged at the front end of the ventilation pipeline, so the air speed and the air volume of the air delivered from an air delivery port which is arranged at the back end of the ventilation pipeline are constant. The air valve device is characterized in that the air valve device is provided with an air sensing part, an adjusting part, a connecting part and a limiting part, wherein the air sensing part is arranged at the air delivery port, and is used for sensing the air volume and the air speed, the air sensing part comprises a fixing framework, a limiting framework, an air sensing framework, a distance adjusting unit and a thrust component, the adjusting part is arranged at one side, near the air inlet, of the inside of the ventilation pipeline, and is used for adjusting the air volume and the air speed, the adjusting part comprises a first rotary shaft, a plurality of blade components, a blade driving rod, a support framework, an air retaining plate, a rotary gear, an adjusting component and a thrust component, the connecting part is used for connecting the air sensing part with the adjusting part, and comprises a second cable and a steering pulley block, and the limiting part comprises a first limiting table, a second limiting table and a third limiting table.

Description

technical field [0001] The invention relates to a damper device. Background technique [0002] In the air supply outlet of air conditioners and the air supply outlets of some buildings, in order to adjust the wind speed so that the wind can be sent out of the air outlet more evenly, and at the same time to adjust the air volume to a suitable size, so that the wind speed and air volume can be kept constant. Valve device, most of the existing air valve devices are mechatronic devices, which greatly increases energy consumption. [0003] Although the existing purely mechanical air valve devices do not require additional energy consumption, because there is no feedback adjustment mechanism in these air valve devices, they can only reduce the flow rate increase trend, so that the flow rate is roughly reduced, but It is difficult to keep the flow of the flow valve constant, and the air cannot be evenly sent out of the air outlet, and the initial value cannot be preset, the functi...
