[0023] 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.

[0024] Reference Figure 1-Figure 3The utility model provides an embodiment: an anti-channeling high-efficiency regulating valve, including a valve body 1, a support seat 4 is fixedly connected to the upper surface of the valve body 1, a rotating rod 5 is rotatably connected inside the support seat 4, a connecting block 3 6 is fixedly connected to the lower end of the outer wall of the rotating rod 5, a valve core 7 is fixedly connected to the outer wall of the connecting block 3 6, a pointer 10 is fixedly connected to the outer wall of the rotating rod 5, a dial 11 is fixedly connected to the upper surface of the support seat 4, a connecting plate 8 is fixedly connected to the upper end of the outer wall of the rotating rod 5, a screw 9 is slidably connected to the inside of the connecting plate 8, and the outer wall screw of the screw 9 is fixedly connected to the outer wall of the screw 9. The groove is connected to the inside of the valve body 1, the top of the rotating rod 5 is fixedly connected to the connecting block 12, the top of the connecting block 12 is rotatably connected to the connecting block 2 13, the outer wall of the connecting block 2 13 is fixedly connected to the handle 14, the inside of the connecting block 12 is provided with an adjusting component, the adjusting component includes a rotating shaft 15, the outer wall of the rotating shaft 15 is rotatably connected to the inside of the connecting block 12, the outer wall of the rotating shaft 15 is fixedly connected to the fixing block 16, the inner top of the connecting block 2 13 is fixedly connected to the sliding block 17, and the outer wall of the sliding block 17 is slidably connected to the inside of the connecting block 12.

[0025] Specifically, the handle 14 is turned to drive the connection block 12 and the connection block 2 13 to rotate. This action will cause the rotating rod 5 to rotate, and then drive the connection block and the valve core 7 to rotate. By adjusting the opening and closing degree of the valve core 7, the flow rate of the medium can be accurately controlled. During the rotation process, the rotating rod 5 will also drive the pointer 10 to rotate above the dial 11. By reading the value on the dial 11, the rotation angle of the valve plate 23 can be conveniently controlled. In addition, when the rotating handle 14 is suddenly released, the connection block 2 13 will drive the slider 17 to hit the fixed block 16. This impact process converts the impact potential energy into the rotation energy of the rotating rod 5, so that the opening and closing degree of the valve core 7 can be more accurately controlled. This design not only improves the response speed of the regulating valve, but also enhances its stability.

[0026] Reference Figure 4 The inner wall of the valve body 1 is fixedly connected with a hinge 22, and the lower surface of the hinge 22 is fixedly connected with a valve plate 23, the outer wall of the valve plate 23 fits with the outer wall of the valve body 1, and the upper end of the outer wall of the valve body 1 is fixedly connected with one end of a return spring 24, and the other end of the return spring 24 is fixedly connected to the inside of the valve body 1. The inner wall of the valve body 1 is threadedly connected with a connecting pipe 31, and the outer wall of the connecting pipe 31 is threadedly connected with a water inlet pipe 19, and the lower end of the outer wall of the water inlet pipe 19 is fixedly connected with a water inlet pipe 20, and the outer walls of the water inlet pipe 19 and the water inlet pipe 20 are both fixedly connected with a flange plate 21.

[0027] Specifically, when the medium flows inside the pipeline, it pushes the valve plate 23 to rotate with the hinge 22. During this process, the valve plate 23 squeezes the return spring 24. When the medium stops flowing, the reaction force of the return spring 24 causes the valve plate 23 to rotate in the opposite direction, thereby preventing the medium from flowing back.

[0028] Reference Figure 4-Figure 5 The outer wall of the valve body 1 is slidably connected with a connecting sleeve 25, and the inner wall of the connecting sleeve 25 is fixedly connected with a sealing ring 18. The outer wall of the sealing ring 18 fits with the outer wall of the connecting pipe 31. The outer wall of the connecting sleeve 25 is fixedly connected with a bracket 26, and the lower surface of the bracket 26 is fixedly connected with a telescopic rod 27. The bottom end of the telescopic rod 27 is fixedly connected with a limiting plate 29, and the lower surface of the limiting plate 29 is fixedly connected with a clamping block 30. The outer wall of the clamping block 30 is slidably connected to the inside of the valve body 1. The outer wall of the telescopic rod 27 is sleeved with a spring 28, one end of the spring 28 is fixedly connected to the lower surface of the bracket 26, and the other end of the spring 28 is fixedly connected to the upper surface of the limiting plate 29. The lower surface of the valve body 1 is fixedly connected with a support foot 2, and the outer wall of the valve body 1 is fixedly connected with a flange plate 3.

[0029] Specifically, when the regulating valve needs to be used, first rotate the connecting pipe 31. The connecting pipe 31 is designed with a fine thread groove inside so that it can be tightly connected to the valve body 1. This step ensures the sealing of the fluid in the pipeline and prevents the possibility of leakage. Next, the connecting sleeve 25 together with the telescopic rod 27 and the block 30 are inserted into the interior of the valve body 1. This step further enhances the stability of the pipeline system. Then, by rotating the valve body 1, the connecting pipe 31 can be connected to the water inlet pipe 19. In addition, the flange plate 3 connected to the valve body 1 and the flange plate 21 connected to the water inlet pipe 20 enable the entire regulating valve to be stably installed. It is worth noting that the position of the water inlet pipe 20 is lower than the water inlet pipe 19. This height difference design helps to prevent turbulence when the medium flows inside the pipeline.

[0030] Working principle: when the device needs to be used, first rotate the connecting pipe 31, connect it with the valve body 1 through the threaded groove inside the connecting pipe 31, then insert the connecting sleeve 25 with the telescopic rod 27 and the block 30 into the interior of the valve body 1, then rotate the valve body 1 with the pipe to connect the connecting pipe 31 with the water inlet pipe 19, and install the entire regulating valve on the flange plate 13 connected to the valve body 1 and the flange plate 21 connected to the water inlet pipe 20. The position of the water inlet pipe 20 is lower than that of the water inlet pipe 20. When the medium flows inside the pipeline, the height difference between the water inlet pipe 20 and the water inlet pipe 19 prevents medium turbulence. At the same time, when the medium flows inside the pipeline, it will push the valve plate 23 to rotate with the hinge 22. When the valve plate 23 rotates, it squeezes the reset spring 24. When the medium stops flowing, the reset spring The reaction force of the spring 24 causes the valve plate 23 to rotate in the opposite direction to prevent the medium from flowing back. When the medium pressure and flow rate need to be adjusted, the handle 14 is turned to cause the connecting block 12 and the connecting block 2 13 to rotate. The connecting block 2 13 is rotated to cause the rotating rod 5 to rotate. The rotation of the rotating rod 5 causes the connecting block and the valve core 7 to rotate. The flow rate of the medium is adjusted by the opening and closing degree of the valve core 7. When the rotating rod 5 rotates, the pointer 10 is rotated above the dial 11. The angle of the rotating valve plate 23 is controlled by reading the value on the dial 11. When the handle 14 is suddenly released, the connecting block 2 13 causes the slider 17 to hit the fixed block 16. The fixed block 16 causes the connecting block 2 13 and the rotating rod 5 to rotate, and the impact potential energy is converted into the rotation energy of the rotating rod 5, so as to achieve more precise control over the opening and closing degree of the valve core 7.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
