[0004] For the above description, the applicant believes that the following problems exist:

[0005] The utility model in the use process, since the device is rotated by motor and connecting rod, the position of valve clack is controlled by eccentric connecting rod, the contact surface of valve clack and valve body inner cavity is controlled to control flow rate, but motor does not have self-locking function, so the position of valve clack cannot be stably controlled by motor driving connecting rod, when the flow rate of passing is large, valve clack will be pushed to shift position, and the size of flow rate cannot be accurately controlled, so a regulating assembly for throttle valve is needed to solve the above problems. Utility model content

[0006] In order to overcome the problem that the position of valve clack cannot be stably controlled by motor driving connecting rod, when the flow rate of passing is large, valve clack will be pushed to shift position.

[0007] The technical solution of this utility model is as follows: an adjusting component for a throttle valve, including a throttle valve body, a hollow cylinder, a sealing plate, a slide rod, a connecting plate, a first spring, a rubber head, a rotating plate, a first bolt, and an installation mechanism.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5This utility model provides an embodiment: an adjusting assembly for a throttle valve, including a throttle valve body 1, and further including a hollow cylinder 22, a sealing plate 23, a sliding rod 24, a connecting plate 26, a first spring 27, a rubber head 25, a rotating plate 211, a first bolt 210, and an installation mechanism. The installation mechanism is provided on the left and right sides of the throttle valve body 1. The hollow cylinder 22 is fixedly connected to the top of the throttle valve body 1. The sealing plate 23 is fixedly connected inside the hollow cylinder 22. The sliding rod 24 is slidably connected inside the sealing plate 23. The bottom of the sliding rod 24 is fixedly connected to a rubber head 25. A connecting plate 26 is fixedly connected to the part, and a first spring 27 is fixedly connected between the connecting plate 26 and the sealing plate 23. A rotating plate 211 is rotatably connected inside the slide rod 24, and a first bolt 210 is fixedly connected to the top of the rotating plate 211. The first bolt 210 is threaded into the inside of the hollow cylinder 22. The first spring 27 applies a thrust to make the first bolt 210 and the hollow cylinder 22 connect and tighten, stabilizing the position of the rubber head 25. The rotation of the connecting cylinder 28 drives the first bolt 210 to rotate. As the first bolt 210 rotates, it descends, pushing the rubber head 25 down, so that the rubber head 25 and the rubber ring are aligned. 21. As the first bolt 210 descends, it compresses the first spring 27 via the connecting plate 26, causing the spring 27 to deform. The spring 27 applies a thrust, securing the first bolt 210 to the hollow cylinder 22, thus preventing the first bolt 210 from loosening. The stable position of the first bolt 210 also prevents the rubber head 25 from loosening. After the rubber head 25 is adjusted and stabilized, the nut 33, in conjunction with the second bolt 32, allows the fixing plate 31 to connect to the flanges of other pipes. The second spring 37 pushes the second bolt 32 to a stable position, which, in conjunction with the nut 33, ensures stable positioning. Nut 33 is provided to prevent the second bolt 32 from loosening, thus making the connection more stable. The slide rod 24 has a limit groove at the corresponding position of the rotating plate 211, and the rotating plate 211 rotates inside the limit groove. By connecting the rotating plate 211 through the limit groove, the first bolt 210 can be raised and lowered simultaneously, and the slide rod 24 can be raised and lowered synchronously through the rotating plate 211. The sealing plate 23 has a limit groove at the corresponding position of the slide rod 24, and the slide rod 24 slides linearly inside the limit groove. The limit groove ensures that the slide rod 24 can only slide linearly, preventing the slide rod 24 from rotating while sliding.

[0023] Please see Figures 1-3In this embodiment, a connecting cylinder 28 is rotatably connected inside the hollow cylinder 22, and a first bolt 210 is slidably connected inside the connecting cylinder 28. A rotating handle 29 is fixedly connected to the outside of the connecting cylinder 28, and a rubber ring 21 is fixedly connected inside the throttle valve body 1. The first bolt 210 can be rotated by manually turning the rotating handle 29 without affecting the up-and-down sliding of the first bolt 210, making adjustment more convenient. The rubber ring 21 has a slanted groove at the corresponding position of the rubber head 25, and the rubber head 25 contacts and cooperates with the rubber ring 21 through the slanted groove. The slanted groove allows the rubber head 25 and the rubber ring 21 to fit tightly together, preventing gaps that could lead to leakage and improving sealing performance.

[0024] Please see Figure 1 , Figures 4-5 In this embodiment, the installation mechanism includes a fixing plate 31, which is fixedly connected to the left and right sides of the throttle valve body 1. A second bolt 32 is movably connected inside the fixing plate 31, and a nut 33 is threadedly connected to the outside of the second bolt 32. A washer 34 is provided outside the second bolt 32, and a first connecting ring 35 and a second connecting ring 36 are provided outside the second bolt 32. A second spring 37 is fixedly connected between the first connecting ring 35 and the second connecting ring 36. The second spring 37 tightens the position of the second bolt 32, and the washer 34 tightens the position of the nut 33, which makes the pipe connected by the second bolt 32 more stable and prevents loosening. The fixing plate 31 has a through hole at the corresponding position of the second bolt 32, and the second bolt 32 passes through the through hole. The second connecting ring 36 and the washer 34 are in contact with the throttle valve body 1, which facilitates the connection of other pipes through the second bolt 32. The contact between the second connecting ring 36, the washer 34 and the fixing plate 31 makes the position of the second bolt 32 more stable.

[0025] During operation, the second bolt 32 passes through the through hole of the fixed plate 31 and then through the through hole of the connecting pipe flange. A washer 34 is then fitted over the second bolt 32, and a nut 33 is screwed onto the outside of the second bolt 32. Twisting the nut 33 pushes the washer 34 against the connecting pipe flange, simultaneously compressing the second spring 37 with the first connecting ring 35 and the second connecting ring 36. The second bolt 32 is then secured by the push of the second spring 37, and with the tightening of the nut 33, the connection of the second bolt 32 is stable. Twisting the handle 29 drives the connecting cylinder 28, which in turn drives the first bolt 210. As the first bolt 210 rotates, it descends, driving the rotating plate 211. The rotating plate 211 drives the sliding rod 24, which, as it descends, compresses the first spring 27 through the connecting plate 26. The sliding rod 24 then adjusts the rubber head 25 to the appropriate position, and the rubber head 25, in conjunction with the rubber ring 21, controls the flow rate.

[0026] Through the above steps, the compressed first spring 27 applies an upward thrust to the first bolt 210, which makes the connection between the threaded first bolt 210 and the hollow cylinder 22 more stable, and makes the self-locking function more stable. This solves the problem that the motor-driven connecting rod control cannot stably control the position of the valve disc, and when the flow pressure is large, it will push the valve disc to shift position.
