Drive assembly 7 includes motor 701 equipped in the top of the inner chamber of casing 301, and the output end of motor 701 is equipped with gear 702, and the lateral surface of the inner chamber of casing 301 is rotatably equipped with driving disc 703, and the top of driving disc 703 is equipped with internal gear ring 704, and internal gear ring 704 is mutually engaged with gear 702, and a plurality of driving arc grooves 705 matched with adjusting part 9 are formed in driving disc 703, and circular groove 706 is formed in driving disc 703 and is movably connected with main installation pipe 302.The adjusting member 9 comprises an adjusting plate 901, the side of the adjusting plate 901 is provided with a driving rod 904, the driving rod 904 is movably connected in the driving arc groove 705, the side of the adjusting plate 901 is provided with a sliding block 903, the other side of the adjusting plate 901 is provided with a sliding groove 902, the two adjacent adjusting plates 901 are slidably connected through the sliding groove 902 and the sliding block 903, one side of the adjusting plate 901 is provided with a limiting block 905, the limiting block 905 is matched with the matching member 8; wherein the matching groove 404 is matched with the adjusting plate 901, thereby forming a sealing effect. The matching member 8 comprises a matching disc 801 provided on the inner wall of the shell 301, the matching disc 801 is provided with a limiting groove 802 slidably connected with the limiting block 905. The main gas flow sensor 5 and the auxiliary gas flow sensor 6 are high-precision gas flow sensors, which can accurately measure the ammonia flow in real time and transmit the flow data to the external control unit.

[0043] The implementation process: when the new ammonia flow regulator starts to work, the main gas flow sensor 5 and the auxiliary gas flow sensor 6 respectively monitor the ammonia flow passing through the main installation pipe 302 and the auxiliary installation pipe 303 in real time, and the two high-precision gas flow sensors transmit the collected ammonia flow data to the external control unit, which provides the basis for subsequent flow regulation. According to the preset ammonia flow value and the real-time flow data fed back by the main gas flow sensor 5 and the auxiliary gas flow sensor 6, the external control unit sends instructions to the motor 701 in the driving assembly 7. After the motor 701 starts, the gear 702 at the output end rotates. Since the gear 702 is meshed with the inner tooth ring 704 on the top of the driving disc 703, the rotation of the gear 702 drives the inner tooth ring 704 and the driving disc 703 to rotate. The circular groove 706 on the driving disc 703 is movably connected with the main installation pipe 302. When the driving disc 703 rotates, the circular groove 706 moves along the main installation pipe 302, which stabilizes the rotation of the driving disc 703. During the rotation of the driving disc 703, the driving arc grooves 705 formed on it rotate, the driving rod 904 of the adjusting piece 9 is movably connected in the driving arc groove 705, the rotation of the driving arc groove 705 drives the driving rod 904 to move, thereby driving the mutual coordinated movement between the plurality of adjusting plates 901. The sliding block 903 on the side of the adjusting plate 901 is slidably connected with the sliding groove 902 on the adjacent adjusting plate 901, which improves the stability of the mutual coordinated movement between the plurality of adjusting plates 901. The adjusting plate 901 adjusts the position under the drive of the driving assembly 7. The limiting block 905 on one side of the adjusting plate 901 is slidably connected with the limiting groove 802 on the matching disc 801 in the matching piece 8, which limits the limiting block 905 and ensures that the adjusting plate 901 moves along the predetermined trajectory. It also assists the adjusting plate 901 to make fine position adjustment. During the movement of the adjusting plate 901, the adjusting plate 901 cooperates with the matching groove 404 of the fixed piece 4, which further ensures the stability of the movement of the adjusting plate 901. With the position adjustment of the adjusting plate 901, the flow area of ammonia in the main installation pipe 302 and the auxiliary installation pipe 303 changes. When the adjusting plate 901 moves away from the fixed column 403, the flow area of ammonia increases, thereby realizing the regulation of ammonia flow. When it is necessary to increase the ammonia flow, the driving assembly 7 drives the adjusting plate 901 away from the fixed column 403, so as to increase the flow area of ammonia. Conversely, when it is necessary to reduce the ammonia flow, the adjusting plate 901 moves towards the fixed column 403, thereby reducing the flow area of ammonia. During the adjustment process, the main gas flow sensor 5 and the auxiliary gas flow sensor 6 continuously monitor the ammonia flow and feed back the new flow data to the external control unit. The external control unit judges whether the current ammonia flow reaches the preset value according to the feedback data. If not, the external control unit adjusts the operating state of the motor 701 again.The driving assembly 7 continues to drive the adjusting member 9 to act until the ammonia flow rate reaches the preset value, so as to realize accurate and dynamic adjustment of the ammonia flow rate.

[0044] The above embodiments are only used to illustrate the technical solutions described in the utility model and not to limit the utility model.
