Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, in particular to a regulating air valve for fresh air equipment. Background Art

[0002] As we all know, at present, air pollution is getting more and more serious, and the use of fresh air system has effectively improved the air environment for residents. The control of air volume by fresh air equipment needs to rely on air valves for adjustment, and for existing fresh air equipment, the air valve is usually set in the air inlet duct.

[0003] Existing fresh air valves mostly use valve plates to control and adjust the air volume. A sealing rubber ring is arranged around the valve plate to play a sealing role. The air valve is frequently opened and closed, and the sealing rubber ring and the inner wall of the fresh air duct are easily worn due to friction, which may easily lead to poor sealing. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides an adjustable air valve for fresh air equipment, which can effectively improve the sealing performance.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjusting air valve for fresh air equipment, including a fresh air duct, a valve is installed in the middle of the fresh air duct, the valve includes a control handle, a drive shaft and a valve plate, and is characterized in that: the top and bottom of the fresh air duct are provided with mounting rings matching the two sides of the valve plate, each of the mounting rings is provided with a sealing ring on the side close to the valve plate, each of the sealing rings is provided with a magnet inside and on the side close to the valve plate, and iron sheets are provided on both sides of the valve plate.

[0008] Furthermore, the mounting ring and the fresh air duct are fixedly connected.

[0009] Furthermore, when the valve plate is in a closed state, two sides of the valve plate abut against the sealing ring.

[0010] Furthermore, the sealing ring is made of rubber.

[0011] (III) Beneficial effects

[0012] Compared with the prior art, the utility model provides a regulating air valve for fresh air equipment, which has the following beneficial effects:

[0013] The regulating air valve of the fresh air equipment is provided with a mounting ring, a sealing ring, a magnet and an iron sheet. When the valve plate is closed, the magnet and the iron sheet are adsorbed together, and the sealing ring can be more closely attached to the valve plate, thereby effectively improving the sealing performance.
