[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The following is combined Figure 1 and Figure 2 The following describes embodiments of the present invention.

[0026] According to an embodiment of the present invention, a regulating valve is provided, comprising: a valve body 1, a valve stem 2, and a rotating disk 5.

[0027] Specifically, the valve stem 2 is movably connected to the valve body 1. The valve stem 2 is adapted to make linear movements within the valve body 1. The valve stem 2 has a drive end 3, which is located outside the valve body 1. The drive end 3 is used to drive the valve stem 2 to move under the action of external force. The valve stem 2 has a drive part 4. The rotating disk 5 is rotatably disposed inside the valve body 1. The rotating disk 5 is provided with a mating part 6 that cooperates with the drive part 4. The rotating disk 5 is located on one side of the valve stem 2, and the drive part 4 cooperates with the mating part 6.

[0028] In this embodiment, the valve body 1 has a valve body channel 10, in which fluid can flow. One end of the valve stem 2 is movably disposed inside the valve body 1. The valve stem 2 can move linearly in a direction close to or away from the valve body channel 10. The other end of the valve stem 2 disposed outside the valve body 1 is a drive end 3. The valve stem 2 can be moved linearly by external force driving the drive end 3. For example, the operator can grip the drive end 3 to drive the valve stem 2 to move. A rotating disk 5 is disposed inside the valve body 1 and located on one side of the valve stem 2. The valve stem 2 and the rotating disk 5 respectively have a driving part 4 and a mating part 6. When the valve stem 2 moves linearly, the driving part 4 on the valve stem 2 moves with the valve stem 2. When the driving part 4 moves, it can drive the mating part 6 to rotate. The mating part 6 drives the rotating disk 5 to rotate. The rotating disk 5 contains a valve core 11. When the rotating disk 5 rotates, the valve core 11 can adjust the opening of the valve body channel 10. When the valve stem 2 moves linearly away from the valve body channel 10, the rotating disk 5 rotates clockwise, and the valve core 11 can reduce the orifice diameter of the valve body channel 10, reducing the fluid flow rate. When the valve stem 2 moves linearly towards the valve body channel 10, the rotating disk 5 rotates counterclockwise, and the valve core 11 can expand the orifice diameter of the valve body channel 10, increasing the fluid flow rate. In other alternative embodiments, when the valve stem 2 moves linearly toward the valve body channel 10, the rotating disk 5 rotates clockwise, and the valve core 11 can reduce the orifice diameter of the valve body channel 10, thereby reducing the fluid flow rate; when the valve stem 2 moves linearly away from the valve body channel 10, the rotating disk 5 rotates counterclockwise, and the valve core 11 can expand the orifice diameter of the valve body channel 10, thereby increasing the fluid flow rate.

[0029] In this embodiment, the regulating valve has a drive unit 4 on the valve stem 2, which makes the valve stem 2 move linearly to drive the rotating disk 5 to rotate. The valve stem 2 no longer needs to be equipped with gears, which simplifies the structure of the valve stem 2 and makes it easier to produce and install the valve stem 2.

[0030] Preferably, the drive part 4 and the mating part 6 each have a toothed structure, and the drive part 4 and the mating part 6 mesh with each other through the toothed structure. The number of teeth in the toothed structure can be determined according to the number of valve stems 2 and the adjustment accuracy of the valve.

[0031] In one embodiment, the mating part 6 is disposed on the outer peripheral surface of the rotating disk 5, the driving part 4 is disposed on the outer peripheral surface of the valve stem 2, and the driving part 4 is located on the side of the valve stem 2 facing the rotating disk 5.

[0032] In this embodiment, as Figure 2 As shown, the valve stem 2 is located on the left side of the rotating disk 5, the drive part 4 is located on the right side of the valve stem 2, and the mating part 6 is disposed on the outer peripheral surface of the rotating disk 5 and meshes with the drive part 4. When the valve stem 2 drives the drive part 4 to move, it can drive the mating part 6 to drive the rotating disk 5 to rotate.

[0033] In this embodiment, as Figure 2 As shown, the valve stem 2 has a groove 7, and the drive part 4 is disposed in the groove 7.

[0034] In one embodiment, the valve body 1 has a guide structure that cooperates with the valve stem 2 to enable the valve stem 2 to move linearly within the valve body 1.

[0035] In this embodiment, the guide structure guides the valve stem 2, causing it to move vertically and preventing the valve stem 2 from deviating from the rotating disk 5 during movement, thus preventing it from driving the rotating disk 5 to rotate. Figure 2 As shown, the guide structure is a valve stem channel 8, which is perpendicular to the valve body channel 10. The valve stem 2 is installed in the valve stem channel 8 and can move along the guide direction of the valve stem channel 8. The valve stem channel 8 is not connected to the valve body channel 10 and is located on one side of the valve body channel 10.

[0036] In one embodiment, the rotary disk 5 has a through hole 9 that communicates with the valve body channel 10 of the valve body 1.

[0037] In this embodiment, as Figure 2 As shown, the rotating disk 5 has a through hole 9. The rotating disk 5 is coaxially arranged with the valve body channel 10, and the through hole 9 is connected to the valve body channel 10.

[0038] In this embodiment, the rotating disk 5 contains a valve core 11, which controls the opening of the through hole 9. When the rotating disk 5 rotates clockwise, the valve core 11 extends from the rotating disk 5 into the through hole 9, thereby reducing the fluid flow rate. When the rotating disk 5 rotates counterclockwise, the valve core 11 retracts from the through hole 9 into the rotating disk 5, thereby increasing the fluid flow rate. The valve core 11 used in this embodiment is the same as the valve core 11 of DISK VALVE manufactured by AMPO. This valve core 11 is well-known in the art, and its principle will not be described in detail here.

[0039] In one embodiment, the drive end 3 is connected to the power output device.

[0040] Preferably, the power output device (not shown) is a cylinder, the output end of which is connected to the drive end 3, and the output end of the cylinder can drive the valve rod 2 to move linearly through the drive end 3.

[0041] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
