Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, and in particular to an electric regulating device for a gate valve. Background Technology

[0002] Gate valves are one of the most important types of valves. They belong to the category of shut-off valves and are used to connect or disconnect the medium in a pipeline. They have two working states: fully closed and fully open. They are widely used for the flow and shut-off of liquids, gases, dust and other media.

[0003] According to a public disclosure of a gate valve (publication number: CN205918924U), it includes a valve body, a valve cover disposed on the valve body, a valve core assembly disposed in the valve cavity of the valve body, a valve stem connected to the valve core assembly, and an operating mechanism connected to the valve stem. The above application document describes the corresponding adjustment operation by manually using an operating handwheel. However, this device requires a staff member to manually adjust it nearby, making the use of the device inconvenient. Utility Model Content

[0004] This invention addresses the inconvenience of manual adjustment in existing technologies. Therefore, it proposes an electric adjustment device for gate valves, which improves the ease of use of the device.

[0005] An electric regulating device for a gate valve includes a gate valve body and a support frame, wherein a stepper motor is fixedly mounted on the side of the support frame.

[0006] An adjustment assembly is provided between the gate valve body and the stepper motor. The adjustment assembly includes a gate valve adjustment handle. A sprocket is driven to the bottom of the stepper motor through its output shaft. A transmission chain is provided on the outer side of the sprocket. A transmission rod is fixedly connected to the top of the gate valve adjustment handle. A sprocket is fixedly connected to the top of the transmission rod.

[0007] Furthermore, one end of the transmission chain is located outside the first sprocket, and the other end of the transmission chain is located outside the second sprocket.

[0008] Furthermore, a locking assembly is provided between the gate valve body and the stepper motor. The locking assembly includes a fixing rod, a ratchet fixedly connected to the top of the second sprocket, a rotating shaft rotatably connected to the side of the fixing rod, a transmission plate one fixedly connected to the front end of the rotating shaft, a pawl fixedly connected to one side of the transmission plate one, a spring fixedly connected to the other side of the transmission plate one, a transmission plate two fixedly connected to the rear end of the rotating shaft, a linear motor fixedly connected to the rear end of the support frame, and a pressing rod driven through its output shaft to the side of the linear motor.

[0009] Furthermore, one end of the spring is fixedly connected to the transmission plate, and the other end of the spring is fixedly connected to the support frame.

[0010] Furthermore, the pawl is located on the side of the ratchet, and the pawl and the ratchet are in an engaged state.

[0011] Furthermore, the extrusion rod is located on the side of the transmission plate two, and the extrusion rod is in contact with the transmission plate two.

[0012] Unlike existing technologies, the beneficial effects of this application are as follows:

[0013] (1) The electric adjustment device of the gate valve starts the stepper motor through the remote operation platform, thereby driving the first sprocket to rotate at a certain angle. Because the first sprocket rotates at a certain angle, and the transmission chain set on the outside of the first sprocket is located on the outside of the second sprocket, the second sprocket rotates synchronously. The second sprocket then drives the transmission rod to rotate, which in turn drives the gate valve adjustment handle to rotate, thereby opening the gate valve body at a certain angle. No staff need to manually adjust it nearby, making the device easier to use.

[0014] (2) The electric regulating device of the gate valve, when the sprocket two drives the gate valve regulating handle to rotate and open, the sprocket two drives the ratchet to rotate. At this time, the ratchet squeezes the pawl, which causes the pawl to drive the transmission plate one to squeeze the spring and generate movement. When the gate valve regulating handle stops rotating, the ratchet is immediately restricted by the pawl, making it difficult to rotate, thus improving the stability of the device during use.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Example 1: Please refer to Figures 1-3 As shown in the figure, an electric regulating device for a gate valve includes a gate valve body 100 and a support frame 200, and a stepper motor 300 is fixedly installed on the side of the support frame 200.

[0031] An adjustment assembly 400 is provided between the gate valve body 100 and the stepper motor 300. The adjustment assembly 400 includes a gate valve adjustment handle 401, and a sprocket 402 is driven to the bottom of the stepper motor 300 via its output shaft. By starting the stepper motor 300 through a remote operating platform, the sprocket 402, which is driven to the output shaft of the stepper motor 300, rotates at a certain angle. A drive chain 403 is provided on the outer side of the sprocket 402. A drive rod 404 is fixedly connected to the top of the gate valve adjustment handle 401, and a sprocket 405 is fixedly connected to the top of the drive rod 404. One end of the drive chain 403 is located on the outer side of the sprocket 402, and the other end of the drive chain 403 is located on the outer side of the sprocket 405. When sprocket 1 402 rotates to a certain angle, and the other end of the transmission chain 403 on the outer side of sprocket 1 402 is located on the outer side of sprocket 2 405, sprocket 2 405 and sprocket 1 402 are connected by the transmission chain 403. This allows sprocket 2 405 and sprocket 1 402 to rotate synchronously to a certain angle. Sprocket 2 405 then drives the transmission rod 404, which is fixedly connected to it, to rotate to a certain angle. This causes the transmission rod 404 to drive the gate valve adjusting handle 401, which is fixedly connected to it, to rotate to a certain angle, thereby opening the gate valve body 100 to a certain angle. This eliminates the need for manual adjustment by personnel nearby, making the device easier to use.

[0032] In use, the stepper motor 300 is started via a remote operation platform, which drives the sprocket 402, which is connected to the output shaft of the stepper motor 300, to rotate a certain angle. Because the sprocket 402 rotates a certain angle, and the transmission chain 403 on the outside of the sprocket 402 is located on the outside of the sprocket 405, the sprocket 405 and the sprocket 402 are connected by the transmission chain 403, so that the sprocket 405 and the sprocket 402 rotate synchronously with the sprocket 402 at a certain angle. The sprocket 405 then drives the transmission rod 404, which is fixedly connected to it, to rotate a certain angle, so that the transmission rod 404 drives the gate valve adjusting handle 401, which is fixedly connected to it, to rotate a certain angle, thereby opening the gate valve body 100 at a certain angle.

[0033] To further improve the stability of the device during use, please refer to Figures 1-4As shown in the figure, a locking assembly 500 is provided between the gate valve body 100 and the stepper motor 300. The locking assembly 500 includes a fixed rod 501, and a ratchet 502 is fixedly connected to the top of the second sprocket 405. When the second sprocket 405 drives the gate valve adjusting handle 401 to rotate and open, the second sprocket 405 drives the ratchet 502 fixedly connected to it to rotate. A rotating shaft 503 is rotatably connected to the side of the fixed rod 501. A transmission plate 504 is fixedly connected to the front end of the rotating shaft 503. A pawl 505 is fixedly connected to one side of the transmission plate 504. The pawl 505 is located on the side of the ratchet 502 and is engaged with the ratchet 502. A spring 506 is fixedly connected to the other side of the transmission plate 504. One end of the spring 506 is fixedly connected to the transmission plate 504, and the other end of the spring 506 is fixedly connected to the support frame 200. When ratchet 502 rotates, it presses against pawl 505, causing pawl 505 to drive transmission plate 504, which is fixedly connected to it, to compress spring 506, resulting in movement. When the gate valve adjusting handle 401 stops rotating, ratchet 502 is immediately restricted by pawl 505, making it difficult to rotate. This improves the stability of the device during use. Transmission plate 507 is fixedly connected to the rear end of rotating shaft 503, and linear motor 508 is fixedly connected to the rear end of support frame 200. A pressing rod 509 is driven to the side of linear motor 508 through its output shaft. The pressing rod 509 is located on the side of transmission plate 507, and there is contact between the pressing rod 509 and transmission plate 507. When it needs to be reset, the linear motor 508 is started, which drives the pressing rod 509 connected to its output shaft. The pressing rod 509 presses the transmission plate 507 and moves it. This works in conjunction with the rotating shaft 503 fixedly connected to the transmission plate 507 and the transmission plate 504 fixedly connected to the rotating shaft 503. As a result, the transmission plate 504 rotates in the opposite direction. The transmission plate 504 then drives the pawl 505 fixedly connected to it to move away from the ratchet 502. At this time, the stepper motor 300 is started, and the gate valve adjusting handle 401 can be rotated and reset, making the device easier to use.

[0034] In use, when sprocket 2 405 drives the gate valve adjusting handle 401 to rotate and open, sprocket 2 405 drives the ratchet 502 fixedly connected to it to rotate. At this time, ratchet 502 squeezes pawl 505, causing pawl 505 to drive the transmission plate 1 504 fixedly connected to it to squeeze spring 506, resulting in movement. When the gate valve adjusting handle 401 stops rotating, ratchet 502 is immediately restricted by pawl 505, making it difficult to rotate. When it needs to be reset, the linear motor 508 is started, causing the linear motor to... The stepper motor 508 drives the extrusion rod 509, which is connected to its output shaft, to extrude the transmission plate 507 and move it. This, in conjunction with the rotating shaft 503 fixedly connected to the transmission plate 507 and the transmission plate 504 fixedly connected to the rotating shaft 503, causes the transmission plate 504 to rotate in the opposite direction. The transmission plate 504 then drives the pawl 505 fixedly connected to it to move away from the ratchet 502. At this time, when the stepper motor 300 is started, the gate valve adjusting handle 401 can be rotated and reset.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
