[0026] The second gear 10 is driven to rotate by the low-speed motor 9, and the meshing transmission of the second gear 10 and the first gear 8 is used to drive the adapter shaft to rotate. It should be noted that since the diameter of the second gear 10 is smaller than that of the first gear 8, that is, the number of teeth of the second gear 10 is less than that of the first gear 8, the rotation adjustment accuracy of the adapter shaft and the opening and closing plate 6 driven by the rotation of the second gear 10 is higher, and the adjustment process is more controllable, thereby driving the opening and closing plate 6 to start synchronous rotation, so that the opening and closing plate 6 starts to open one of the exhaust pipes 5 and close the other exhaust pipe 5, so as to quickly complete the supply switching operation of the two exhaust pipes 5, thereby improving the two-way supply switching efficiency of the gas pipeline.

[0027] like Figure 1 、 Figure 3-Figure 5As shown, the exhaust pipe 5 and the inner wall of the delivery pipe 3 are rotatably connected with a supply regulating assembly, which is used to adjust the gas delivery rate inside the two delivery pipes 3. The supply regulating assembly includes a regulating pipe 11 rotatably connected to the inner wall of the exhaust pipe 5 and the delivery pipe 3 through a sealed bearing. The inner wall of the regulating pipe 11 and the inner wall of the delivery pipe 3 are fixedly connected with a valve plate 12.

[0029] The detailed working process of this utility model is as follows:

[0030] 1. During use, if it is necessary to switch the bidirectional gas supply between the two exhaust pipes 5 and the delivery pipe 3, the low-speed motor 9 can be controlled to start, and the second gear 10 can be driven to rotate by the low-speed motor 9. The meshing transmission of the second gear 10 and the first gear 8 is used to drive the adapter shaft to rotate, thereby driving the opening and closing plate 6 to start synchronous rotation, so that the opening and closing plate 6 starts to open one of the exhaust pipes 5 and close the other exhaust pipe 5, so as to quickly complete the supply switching operation of the two exhaust pipes 5, thereby improving the bidirectional supply switching efficiency of the gas pipeline;

[0031] 2. If it is necessary to independently adjust the gas delivery rate of the two delivery pipes 3, the rotary motor 14 can be controlled to start, and the worm 15 can be driven to rotate by the rotary motor 14. The meshing transmission of the worm 15 and the worm wheel 13 is used to drive the regulating pipe 11 to rotate, so that the two valve plates 12 on the inner wall of the regulating pipe 11 and the inner wall of the delivery pipe 3 are relatively fitted and rotated at a certain angle, thereby changing the degree of connectivity of the regulating through holes on the two valve plates 12, realizing independent control and adjustment of the gas rate inside the delivery pipe, and improving the practicality of the two-way supply switching device of the gas pipeline.
