A seal is provided between the screw rod 5 and the valve body 1. A damping shaft 8 is fixedly connected to the inner side of the valve body 1 and located on one side of the water inlet pipe 2. The fixed axis of the damping shaft 8 is fixedly connected to the inner wall of the valve body 1. A baffle 9 is fixedly connected to the rotating axis of the damping shaft 8. A baffle 6 is fixedly connected to the inner side of the valve body 1 and located on one side of the water outlet pipe 3. A rubber sheet 7 is provided on the top of the baffle 6. The rubber sheet 7 has a certain curvature, and the baffle 9 can be deflected along the rubber sheet 7.

[0027] The inner side of the valve body 1 is fixedly connected with a sealing plate 11, the inner side of the sealing plate 11 is located on the side of the gear 15 and is rotatably connected with a threaded sleeve 19, the outer side of the threaded sleeve 19 is fixedly connected with a gear 2 18, the screw 15 passes through the threaded sleeve 19 and is threadedly connected with the threaded sleeve 19, the bottom of the valve stem 4 extends to the top of the sealing plate 11 and is fixedly connected with a gear 15, the gear 15 is meshed with the gear 2 18, the valve stem 4 drives the gear 15 to rotate, and then drives the gear 2 18 to rotate, the inner side of the valve stem 4 A screw rod 12 is connected to the side thread, and a piston 13 is fixedly connected to the bottom of the screw rod 12. The piston 13 is used to push the partition 9 to deflect. A sealing strip is provided at the end of the partition 9. A limiting groove 16 is provided on the inner wall of the screw rod 12. The screw rod 12 passes through the inner wall of the sealing plate 11, and a sealing rubber film is provided between the screw rod 12 and the sealing plate 11. A limiting block 17 is fixedly connected to the inner wall of the sealing plate 11 and located on the inner side of the limiting groove 16, and the limiting block 17 can slide along the inner side of the limiting groove 16.

[0028] Working principle: When the water flow rate of the water pump valve is at its maximum, the valve stem 4 is rotated clockwise. Under the limiting action of the limiting block 17 and the limiting groove 16, the screw rod 12 will move up along the inner wall of the valve stem 4, thereby driving the piston 13 to move up. At this moment, under the action of the damping shaft 8, the rotating shaft of the damping shaft 8 will drive the partition 9 to deflect upward until the partition 9 deflects to a horizontal position. The rotating shaft of the damping shaft 8 no longer moves. At this time, the valve stem 4 continues to be rotated, so that the screw rod 12 drives the piston 13 to rise to the bottom of the sealing plate 11. In this process, the rotation of the valve stem 4 will drive the rotation of the gear 15. The first gear 15 meshes with the second gear 18, so that the second gear 18 will rotate, thereby driving the threaded sleeve 19 to rotate on the inner side of the sealing plate 11. Since the inner wall of the screw rod 15 is provided with a card slot, the card block 20 is embedded in the card slot to limit the rotation of the screw rod 15. At this moment, the screw rod 15 will move up along the inner side of the sealing plate 11, thereby lifting the baffle plate 14. When the piston 13 rises to the bottom of the sealing plate 11, the bottom of the baffle plate 14 completely rises above the water outlet pipe 3, and the water outlet pipe 3 is no longer blocked. At this time, water flows from the water inlet pipe 2 into the valve body 1, and flows out through the water outlet pipe 3 again, and the water flow is maximum.

[0029] Similarly, rotating the valve stem 4 counterclockwise can cause the partition plate 9 to deflect, and at the same time make the baffle plate 14 gradually block the water outlet pipe 3, so that the water flow rate is reduced;

[0030] When the valve body 1 is used for a long time, sludge and garbage will appear in the valve body 1, and the sludge and garbage will gradually settle to the bottom of the valve body 1. At this time, the water flow rate is appropriately reduced to clean the sludge and garbage at the bottom of the valve body 1. By rotating the valve stem 4 counterclockwise, the screw rod 12 pushes the piston 13 to squeeze the partition 9 until the partition 9 contacts the surface of the retaining frame 6, and a seal is formed under the action of the rubber sheet 7, so that the water flow cannot pass through the partition 9. The water flow will flush the bottom of the valve body 1 under the shielding effect of the partition 9, and then flush the sludge and garbage from the inner side of the retaining frame 6, avoiding the phenomenon of sludge and garbage deposition, so that the water pump valve can continue to adjust the water flow, avoiding the blockage of the water pump valve, which is conducive to the long-term use of the water pump valve;

[0031] When it is necessary to close the water pump valve, the valve stem 4 continues to be rotated counterclockwise to make the screw rod 12 continue to move downward. At this moment, the partition plate 9 will continue to deflect along the surface of the gear frame 6. During this process, the piston 13 will gradually move downward to block the water outlet pipe 3 until the piston 13 contacts the gear frame 6. The piston 13 completely blocks the water outlet pipe 3, thereby closing the water pump valve.
