DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

The moving mechanism includes a first motor 7, a first gear 9, a first rack 10, and a push plate 11. The first motor 7 is fixedly connected to the interior of the main body 1, and the front end of the first motor 7 is connected to the first gear 9, a first rack 10, and a push plate 11. A gear 9 is fixedly connected, and the first gear 9 is meshed with the first rack 10, the front end of the first rack 10 is fixedly connected to the push plate 11, and the push plate 11 is provided with a through hole 14, and the rear end of the push plate 11 is fixedly connected to the moving rod 12, and the moving rod 12 is connected to the inside of the main body 1 through a sliding connection, the main body 1 is provided with a through hole 14, and the through holes 14 are arranged in an array with respect to the main body 1 and the push plate 11, and the through holes 14 in the main body 1 and the through holes 14 in the push plate 11 are staggered, and the push plate 11 is provided with a through hole 14;

[0025] First, when using, after connecting the two ends of the main body 1 to the outside through threads, the gas enters the inside from the left side of the main body 1. At this time, the push rod 4 inside the fixed plate 3 can be started by the controller 2 to drive the front moving plate 5 to move inside the fixed plate 3. Since a plurality of through holes 14 are provided on both sides of the fixed plate 3, the through holes 14 are blocked by the movement of the moving plate 5 to control the flow of gas. At the same time, the first motor 7 can be started to drive the first gear 9 to rotate. Since the first gear 9 and the first rack 10 are meshed, the first rack 10 drives the front push plate 11 to move. At the same time, the push plate 11 drives the moving rod 12 to slide inside the main body 1. The moving rod 12 can prevent the gas from entering the inside and causing damage to the first motor 7. Since the push plate 11 and the through holes 14 inside the main body 1 are staggered, the farther the distance between the push plate 11 and the inside of the main body 1, the faster the flow rate, and the better the flow control can be;

[0026] The interior of the main body 1 is connected to the adjustment plate 6 through a hinge shaft, the adjustment plate 6 is symmetrically arranged about the center of the main body 1, and the rear ends of the adjustment plate 6 are connected to the main body 1 through the hinge shaft, and the adjustment plate 6 is an arc-shaped plate, and the interior of the main body 1 is connected to the baffle 8 through a pushing mechanism, and the pushing mechanism includes a second motor 15, a second gear 16, a second rack 17, a fixed rod 18, and a baffle 8. The second motor 15 is fixedly connected to the interior of the main body 1, and the front end of the second motor 15 is fixedly connected to the second gear 16, and the second gear 16 is meshed with the second rack 17, the front end of the second rack 17 is fixedly connected to the baffle 8, and the second rack 17 is connected to the fixed rod 18 through a sliding connection, and the fixed rod 18 is fixedly connected to the interior of the main body 1, and the second motor 15 and the first motor 7 are both stepping motors;

[0027] When in use, the gas enters and pushes the adjustment plate 6 to be adjusted through the hinge axis. The faster the gas flow rate, the greater the opening distance of the adjustment plates 6 on both sides. At the same time, the adjustment plate 6 can prevent the gas from flowing in the opposite direction. At the same time, the internal filter 13 can filter impurities in the gas. When the valve needs to be closed, it is only necessary to start the second motor 15 through the controller 2 to drive the second gear 16 to rotate. Since the second gear 16 and the second rack 17 are meshed, the second rack 17 slides on the fixed rod 18 and then drives the baffle 8 to slide inside the main body 1, blocking the right side of the main body 1. At this time, the valve is closed.

[0028] Working principle: When using the desulfurization tower valve that is easy to control the flow rate, first connect the two ends of the main body 1 to the outside through threads, and the gas enters the inside from the left side of the main body 1. At this time, the push rod 4 inside the fixed plate 3 can be started by the controller 2 to drive the front moving plate 5 to move inside the fixed plate 3. Since multiple through holes 14 are provided on both sides of the fixed plate 3, the through holes 14 are blocked by the movement of the moving plate 5 to control the flow of the gas. At the same time, the first motor 7 can be started to drive the first gear 9 to rotate. Since the first gear 9 and the first rack 10 are meshed, the first rack 10 drives the front push plate 11 to move, and at the same time, the push plate 11 drives the moving rod 12 to slide inside the main body 1. The moving rod 12 can prevent the gas from entering the interior and causing The first motor 7 is damaged. Since the push plate 11 and the through holes 14 inside the main body 1 are staggered, the farther the distance between the push plate 11 and the inside of the main body 1, the faster the flow rate, and the better the flow rate can be controlled. At the same time, when in use, the gas enters the push adjustment plate 6 for adjustment through the hinge axis. The faster the gas flow rate, the greater the opening distance of the adjustment plates 6 on both sides. At the same time, the adjustment plate 6 can prevent the gas from flowing in reverse, and the internal filter 13 can filter impurities in the gas. When the valve needs to be closed, it is only necessary to start the second motor 15 through the controller 2 to drive the second gear 16 to rotate. Since the second gear 16 and the second rack 17 are meshed, the second rack 17 slides on the fixed rod 18 and then drives the baffle 8 to slide inside the main body 1, blocking the right side of the main body 1. At this time, the valve is closed.
