[0026] As shown in Figure 1 - Figure 4As shown, the drive assembly includes a fixed box 5, which has a cavity 6. A heat dissipation window 7 is provided on one side of the fixed box 5. A cover 8 is movably mounted on the top of the fixed box 5. A fixed plate 9 is fixedly mounted inside the cavity 6 of the fixed box 5. A motor 10 is fixedly mounted on one side of the fixed plate 9. A bevel gear 11 is movably mounted on the other side of the fixed box 5 and is fixedly connected to the output end of the motor 10. A bevel gear 2 12 is movably mounted on one side of the bottom of the bevel gear 11. The bevel gear 2 12 is connected to the bevel gear 11. 11 meshing connection, a spindle 13 is fixedly installed at the bottom end of bevel gear 11, the spindle 13 passes through the connecting pipe 4 and is movably connected to the valve plate inside the valve body 1, a locking block 14 is fixedly installed on one side of the spindle 13, a groove 15 is opened at the top of the valve plate 3, a limiting groove 16 is opened at the top of the valve plate 3, the limiting groove 16 communicates with the groove 15, the spindle 13 is movably engaged with the groove 15 of the valve plate, the locking block 14 on one side of the spindle 13 is movably engaged with the limiting groove 16 of the valve plate, the limiting groove 16 of the valve plate 3 and the locking block 14 cooperate with each other. The spindle 13 and valve plate are positioned to limit their movement. A bearing 17 is installed inside the top of the connecting pipe 4, engaging with the top of the spindle 13. A groove 18 is provided at the bottom of the valve body 1, housing a bearing 19. The spindle 13 penetrates the sealing ring 2 and engages with the bearing 19. A sealing ring 2, made of synthetic rubber, is also movable inside the valve body 1. The valve plate 3 is movable and engaged with the sealing ring 2, and is made of aluminum alloy. The motor 10 drives the fixed... On the other side of the fixed plate 9, bevel gear 11 rotates, and bevel gear 11 meshes with bevel gear 12 at the bottom and rotates, driving the spindle 13 at the bottom of bevel gear 12 to rotate. The spindle 13 rotates inside the connecting pipe 4, and the locking block 14 on the spindle 13 engages with the limiting groove 16 at the top of the valve plate 3, so that the rotation of the spindle 13 drives the valve plate to rotate. When the angle between the valve plate and the sealing ring 2 increases, the flow of dust and gas medium is accelerated; conversely, when the angle between the valve plate and the sealing ring 2 decreases, the flow of dust and gas medium is reduced.

[0027] Working principle: First, the flange on the pipeline is connected to the flanges on both sides of the valve body 1 to install the device on the dust and gas pipeline. When it is necessary to control the flow rate of the medium inside the dust and gas pipeline, the motor 10 inside the fixed box 5 at the top of the valve body 1 can be started by the control switch. The motor 10 drives the bevel gear 11 on the other side of the fixed plate 9 to rotate through the output shaft. The bevel gear 11 meshes with the bevel gear 12 at the bottom and rotates, driving the spindle 13 at the bottom of the bevel gear 12 to rotate.

[0028] The spindle 13 rotates inside the connecting pipe 4. The locking block 14 on the spindle 13 engages with the limiting groove 16 at the top of the valve plate 3, causing the valve plate to rotate while the spindle 13 rotates. The increased angle between the valve plate and the sealing ring 2 accelerates the release of dust and gas medium, while the decreased angle between the valve plate and the sealing ring 2 reduces the flow of dust and gas medium. During later maintenance, the parts on the device can be removed for repair and the sealing ring 2 can be replaced, which improves the efficiency of the electric dust and gas valve.

[0029] The above merely describes a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent substitutions or changes within the technical range disclosed by the present application, which should be covered within the scope of protection of the present application.
