Synchro control crossed reversing type double-path air flow adjusting device

The utility model discloses a synchro control crossed reversing type double-path air flow adjusting device, which comprises a box body, a linkage shaft and an executing mechanism, wherein an upper circulation air channel and a lower circulation air channel are respectively and vertically formed in the box body; an upper circulation air pipe and a lower circulation air pipe are arranged between the upper circulation air channel and the lower circulation air channel; an upper circulation air valve is arranged in the upper circulation air pipe; a lower circulation air valve is arranged in the lower circulation air pipe; the upper circulation air valve and the lower circulation air valve are mutually vertical and are coaxially arranged on the linkage shaft; the linkage shaft is connected with the executing mechanism; an air return port and an air inlet are formed in the box body. According to the synchro control crossed reversing type double-path air flow adjusting device, the upper and lower circulation air valves are controlled by the same executing mechanism to alternatively open and close so as to realize the wind direction reversing circulation mode that the lower circulation air channel feeds air and the upper circulation air channel returns air or the upper circulation air channel feeds air and the lower circulation air channel returns air; the synchro control crossed reversing type double-path air flow adjusting device has the advantages that the structure is simple, the operation is simple and convenient, and the manufacturing cost is low.
