[0027] See also Figure 1-4The utility model provides a dual-air duct reversing air valve, including an air valve body 1, a valve plate 2 and a driver 3. The air valve body 1 is a frame-type dual-channel structure, including a first channel frame 11 and a second channel frame 12. One side of the first channel frame 11 and the second channel frame 12 are butt-jointed at a fixed angle, and a corner 13 is formed after the butt-jointing. The middle of the first channel frame 11 and the second channel frame 12 is an air duct, and the fixed angle after the two are connected is determined by the design requirements of the air purification system. In this embodiment, the fixed angle is 90 degrees.

[0028] A rotating shaft 21 is provided on one side of the valve plate 2. The rotating shaft 21 can be rotatably embedded and installed at the corner 13. One end of the rotating shaft 21 is connected to the driver 3. Under the driving control of the driver 3, the valve plate 2 rotates around the rotating shaft 21 as the central axis. A driver fixing platform 14 is provided at one end of the corner 13 of the air valve body 1. The driver 3 is fixedly installed on the driver fixing platform 14. The driver fixing platform 14 is provided with a through hole. The driving shaft of the driver 3 passes through the through hole and is connected to the rotating shaft 21.

[0029] Further Figure 2 As shown, in this embodiment, a stop slot 22 is provided at one end of the rotating shaft 21, and a latch 23 is provided at the other end. After the driving shaft of the driver 3 is inserted into the stop slot 22 and fixed with a fastener, a detachable fixed connection is formed with the rotating shaft 21; a valve plate fixing plate 15 is provided on the outer side of the other end of the air valve body 1 relative to the driver fixing platform 14, and the latch 23 is inserted into the frame of the air valve body 1 and passes through the valve plate fixing plate 15, so that a rotatable connection is formed between the rotating shaft 21 and the air valve body 1.

[0030] Further Figure 1 , Figure 2 and Figure 3 As shown, valve plate limiting plates 16 are provided in the frames of the first channel frame 11 and the second channel frame 12. When the channel is closed, the driver 3 drives the valve plate 2 to rotate until the valve plate 2 is completely fitted with the channel and then blocked by the valve plate limiting plates 16.

[0031] Further Figure 2 and Figure 4 As shown, the two sides of the three sides of the valve disc 2 that are not connected to the rotating shaft 21 are provided with raised edges 24, and the valve disc limit plate 16 of the first channel frame 11 and the second channel frame 12 is provided with a sealing groove 18 on the side facing the valve disc 2, and a sealing strip 19 is embedded and installed in the sealing groove 18. The sealing strip 19 is a soft edge sealing material. When the channel is closed, the raised edge 24 of the valve disc 2 will be embedded in the sealing strip 19, squeezing the sealing strip 19 so that the sealing strip 19 can completely fill the sealing groove 18, thereby improving the sealing effect. A sealing strip (not shown in the figure) is also provided at the rear of the rotating shaft 21 (the side facing the corner 13), which fits the rotating shaft 21 to ensure that the air valve does not leak air during use.

[0032] Further Figure 2 and Figure 4 As shown, an arc-shaped groove 17 is provided at the corner 13 for the rotating shaft 21 to be placed and installed, so that the valve plate 2 can be embedded in the first channel frame 11 and the second channel frame 12 after closing.

[0033] Further as Figure 1 , Figure 2 and Figure 3 As shown, a buckle 4 is provided on the outside of one side of the outer frame of the air valve body 1, and a fixed flange plate 5 is provided on the outside of the other side. A plurality of fixing holes are opened on the fixed flange plate 5. When installing the air valve on the unit, first insert the buckle 4 into the slot reserved on the unit and slide it to the locking position, and then use fasteners to lock the fixing holes to complete the installation operation, thereby improving production efficiency.

[0034] The assembly method of this embodiment is that the valve plate 2 is placed in the air valve body 1 and between the valve plate limit plates 16, the driving shaft of the driver 3 passes through the hole on the driver fixing platform 14 and then is inserted into the stop slot 22 designed at one end of the valve plate 2, and the driver 3 is fixed with fasteners, and finally the valve plate fixing plate 15 is installed at the other end of the outer frame of the air valve body 1.

[0035] In actual use, the dual-duct reversing air valve is installed on two vertically adjacent duct openings through a fixed flange. When the equipment runs to the duct switching instruction, the dual-duct reversing air valve switches the two ducts under the drive of the driver, so that one air valve controls the opening or closing of the two ducts, saving space and reducing the number of valves. The rotating shaft 21 is set at one end of the valve plate 2, which is different from the rotating shaft of the prior art that is located at the center.

[0036] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
