[0029] A second rotating disk 15 is disposed on the rotating disk 6, and a pull rod 16 is connected to the bottom of the second rotating disk 15. The pull rod 16 passes through the rotating disk 6 and extends to the bottom of the inner cavity of the rotating rod 5. The pull rod 16 can move up and down;

[0030] An open slot is provided on the first flow component 7 and extends to the bottom of the first flow component 7. A pull plate 17 is provided in the open slot. The pull plate 17 is connected to the pull rod 16 and moves up and down through the pull rod 16.

[0031] The ends of the first flow component 7 and the second flow component 8 are both provided with a sealing gasket 501, and the first flow component 7 and the second flow component 8 are sealed with the inner wall of the regulating valve body 1 through the sealing gasket 501. The first flow component 7 and the second flow component 8 can also be sealed with the left valve disc 12 through the sealing gasket 501 to achieve the separation of the left water inlet chamber and the right water inlet chamber;

[0032] A round block 601 is also fixed on the turntable 6, and a notch 602 is formed on the round block 601. The turntable 6 rotates so that the turntable 6 and the notch 602 rotate accordingly, and the number of revolutions of the turntable 6 is determined according to the direction of the notch 602.

[0033] The first flow component 7 is provided with a first opening 701 and a second opening 702. The first opening 701 is provided at the rear side of the first flow component 7 and is not connected. A plurality of second openings 702 are provided and are arranged side by side at equal distances on the first flow component 7. The second openings 702 all penetrate the first flow component 7.

[0034] The second flow component 8 is provided with a water outlet 801, and the inner diameter of the water outlet 801 is larger than the inner diameter of the second opening 702;

[0035] The pull plate 17 is provided with a rubber block 1701, which is a hemispherical convex block. The rubber block 1701 is located in the first opening 701. The diameter of the rubber block 1701 is consistent with the first opening 701 and the second opening 702. When the pull plate 17 moves up and down, the rubber block 1701 will move up and down with the pull plate 17. When the rubber block 1701 moves up and down, it will rub back and forth in the first opening 701 and the second opening 702. When the rubber block 1701 is located in the second opening 702, one row of the second openings 702 will be blocked so that water cannot flow out.

[0036] It also includes a regulating valve, including the above-mentioned flow regulating component. In the regulating valve, the regulating valve body 1 is subjected to the first flow regulation through the valve flap 4 and the second flow regulation is performed through the regulating component. The third flow regulation can be achieved by cooperating with the valve flap 4 and the regulating component, and the fourth flow regulation can be performed through the rubber block 1701 in the regulating component.

[0037] For example, the flow regulation of regulating valve body 1:

[0038] Under normal circumstances, the valve flap 4 is in a closed state, that is, the left valve flap 12 is tightly fitted with the first sealing gasket 10, and the second sealing gasket 13 is tightly fitted with the right water inlet chamber. At this time, since the fixed end of the hinged end 14 faces the water inlet end of the regulating valve body 1, the regulating valve body 1 does not pass water at this time;

[0039] The valve stem 3 is rotated by rotating the adjusting disk 2, thereby driving the valve flap 4 to rotate, so that the valve flap 4 and the regulating valve body 1 are perpendicular to each other. At this time, both the left water inlet cavity and the right water inlet cavity are flowing with water, and the water output of the regulating valve body 1 is the maximum.

[0040] Continue to rotate the adjusting disk 2, so that the second sealing gasket 13 and the first sealing gasket 10 are in a close and sealed state. At this time, the left valve flap 12 is located in the right water inlet chamber and is not in a close and sealed state because there is no sealing gasket. In addition, since the movable end of the hinged end 14 faces the water inlet end of the regulating valve body 1, the impact force of the water flow will cause the left valve flap 12 to open. At this time, only the right water inlet chamber of the regulating valve body 1 will discharge water.

[0041] When the regulating valve body 1 and the valve disc 4 work, the regulating components cooperate to work. Under normal conditions, the water outlet 801 on the second flow component 8 discharges water. The water outlet 801 is an opening set for the maximum water output, so its diameter is also relatively large.

[0042] When the rotating disk 6 rotates, the rotating rod 5 rotates, thereby exchanging the positions of the first flow component 7 and the second flow component 8, thereby changing the water outlet end, and the water is discharged from the second opening 702 of the first flow component 7;

[0043] In the above situation where only the right water inlet cavity discharges water, the left valve flap 12 will be opened due to the impact force of the water flow. At this time, the opened left valve flap 12 will be in close contact with the sealing gasket 501 on the first flow component 7 or the second flow component 8. Therefore, not only will water only flow out of the right water inlet cavity, but also only half of the first flow component 7 or the second flow component 8 will discharge water.

[0044] In order to prevent the second opening 702 from being blocked due to its small diameter, the second rotating disk 15 is pressed down, and the second rotating disk 15 drives the pull rod 16 and the pull plate 17 to press down. At this time, the rubber block 1701 located in the first opening 701 will move downward due to the elasticity of the rubber itself. At this time, the rubber block 1701 will push out and dredge the second opening 702. After the dredging is completed, the second rotating disk 15 is pulled up to return to its original position;

[0045] When the rubber block 1701 pushes out and clears the second openings 702, since the rubber block 1701 seals one row of the second openings 702, the flow of the first flow component 7 can be limited again without returning to its original position.

[0046] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
