[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1 - Figure 5 As shown, the utility model provides a technical solution: a throttle valve for controlling the flow rate of a fluid, comprising a valve body 1, a lifting assembly 2, and a display assembly 3, wherein the lifting assembly 2 is arranged on the valve body 1, the display assembly 3 is arranged on a side of the valve body 1 away from the lifting assembly 2, a transmission assembly 5 is arranged between the lifting assembly 2 and the display assembly 3, a sealing assembly 4 is arranged on one end of the lifting assembly 2 close to the display assembly 3, and a valve seat 6 is fixedly connected to the bottom of the inner wall of the valve body 1;

[0030] like Figure 2 As shown, the lifting assembly 2 includes a connecting rod 21 and a hydraulic telescopic rod 22, the connecting rod 21 is arranged at the top of the valve body 1, and a fixed block 24 is fixedly connected to the top of the valve body 1 near the connecting rod 21. The connecting rod 21 is rotatably connected to the fixed block 24, and the hydraulic telescopic rod 22 is rotatably connected between the connecting rod 21 and the valve body 1. A valve core 23 is arranged on the side of the connecting rod 21 near the valve body 1, and the valve core 23 is movably inserted on the valve body 1. By installing the connecting rod 21 between the hydraulic telescopic rod 22 and the valve core 23, the hydraulic telescopic rod 22 is started, and the hydraulic telescopic rod 22 contracts to drive the connecting rod 21 to rotate along the fixed block 24, so that the connecting rod 21 lifts the valve core 23 and separates the valve core 23 from the valve seat 6, so that the valve body 1 can be quickly opened, which is convenient for the use of the throttle valve, and the flow of the throttle valve can be accurately controlled according to the contraction degree of the hydraulic telescopic rod 22.

[0031] A connecting block 26 is fixedly connected to one side of the valve core 23 near the connecting rod 21, and an inner groove 25 is provided on one side of the connecting rod 21 near the connecting block 26. The valve core 23 is movably connected to the connecting rod 21 through the inner groove 25 and the connecting block 26. By providing the inner groove 25, the connecting block 26 can move along the inner groove 25. When the connecting rod 21 lifts the valve core 23, the valve core 23 is lifted by the connecting rod 21 along the inner groove 25, thereby separating the valve core 23 from the valve seat 6.

[0032] A slider 27 is fixedly connected to one side of the valve core 23 close to the valve body 1, and a slide groove 28 is provided on one side of the valve body 1 close to the slider 27. The slider 27 is slidably connected to the slide groove 28. By installing the slider 27 on the valve core 23, the valve core 23 slides along the slide groove 28 through the slider 27, which facilitates the movement of the valve core 23 on the valve body 1 and can also make the connection between the valve core 23 and the valve body 1 more secure, thereby avoiding the problem of shaking and deviation of the valve core 23 when moving.

[0033] The above solution still has the problem that when the valve body 1 is opened, the worker cannot accurately read the flow rate according to the contraction degree of the hydraulic telescopic rod 22, and cannot meet the problem of complex on-site use, such as Figure 1 and Figure 4 As shown, the display assembly 3 includes a scale 31 and a pointer 32. The scale 31 is fixedly connected to the valve body 1, and the pointer 32 is rotatably connected to the scale 31. A rotating shaft 33 is rotatably connected to the side of the scale 31 close to the pointer 32, and a driving wheel 34 is fixedly connected to the rotating shaft 33. An end of the pointer 32 close to the driving wheel 34 is fixedly connected to a driven wheel 35, and the driving wheel 34 is meshed with the driven wheel 35. By installing the scale 31 on the valve body 1, a scale can be provided on the scale 31, and the scale indicates the flow rate of the throttle valve. When the driving wheel 34 rotates, the driven wheel 35 drives the pointer 32 to rotate synchronously with the driving wheel 34, so that the pointer 32 points to different scales on the scale 31, so that the worker can accurately read the current flow rate of the throttle valve, which is convenient for controlling the flow rate of the throttle valve.

[0034] The transmission assembly 5 includes a moving plate 51 and a tooth column 52. The moving plate 51 is fixedly connected to the side of the valve core 23 close to the pointer 32. The side of the moving plate 51 close to the driving wheel 34 is fixedly connected to the tooth column 52. The tooth column 52 is transmission-connected to the pointer 32 through the driving wheel 34 and the driven wheel 35. When the valve core 23 is lifted, the moving plate 51 and the valve core 23 are lifted synchronously, so that the moving plate 51 drives the driving wheel 34 to rotate through the tooth column 52, thereby driving the pointer 32 to rotate.

[0035] like Figure 5As shown, the sealing assembly 4 includes a sealing base 41 and a sealing gasket 42. The sealing base 41 is fixedly connected to the inside of the valve body 1, and the sealing gasket 42 is fixedly connected to the sealing base 41. The valve core 23 is movably inserted into the sealing base 41 and the sealing gasket 42. A sealing ring 43 is provided on the side of the sealing base 41 close to the valve core 23. By fixing the sealing base 41 on the valve body 1 and installing the sealing ring 43 inside the sealing base 41, the valve core 23 and the sealing base 41 are sealed to prevent the fluid from flowing out from between the valve core 23 and the sealing base 41. A sealing gasket 42 is added to the sealing base 41 to further enhance the leakage prevention.

[0036] Working principle:

[0037] like Figure 1 - Figure 5 As shown, the fluid is sent into the interior of the valve body 1, and the hydraulic telescopic rod 22 is started. The hydraulic telescopic rod 22 contracts and drives the connecting rod 21 to rotate along the fixed block 24, so that the connecting rod 21 cooperates with the connecting block 26 through the inner groove 25 to lift the valve core 23, so that the valve core 23 is separated from the valve seat 6, and the flow flows out from the interior of the valve body 1, so that the worker can quickly open the valve body 1 and accurately control the fluid flow.

[0038] When the valve core 23 is lifted, the movable plate 51 moves upward synchronously with the valve core 23, so that the valve core 23 drives the pointer 32 to rotate through the driving wheel 34 and the driven wheel 35, so that the pointer 32 points to the scale 31 according to the contraction degree of the hydraulic telescopic rod 22 and the gap between the valve core 23 and the valve seat 6, so that the workers can quickly and accurately read the flow size, so that the workers can accurately control the flow size of the water-saving valve.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
