DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: a regulating valve for agricultural irrigation, including a valve body 1, as Figure 1 shown, having a tubular structure for allowing irrigation water to flow through; both ends of the valve body 1 can be connected to flanges (not shown in the figure) to facilitate the connection between the valve body 1 and the water supply pipeline. A valve includes a circular plate 2 and a plug 3 fixedly connected inside the valve body 1, as Figure 2 shown. A conical through groove 4 is provided through the end face of the circular plate 2, and the plug 3 is located at the conical through groove 4 for regulating the water flow. By controlling the movement of the plug 3 along the axial direction of the valve body 1 and controlling the gap between the plug 3 and the conical through groove 4, the water flow can be regulated; an adjusting mechanism includes a movable plate 5 movably arranged inside the valve body 1, as Figure 2 shown. The movable plate 5 is arranged at the front end of the valve, and a plurality of through grooves 6 for water flow to pass through are provided through the end face of the movable plate 5. An elastic element is arranged between the movable plate 5 and the valve body 1, and a connecting rod 7 is connected between the movable plate 5 and the plug 3. The elastic element causes the movable plate 5 to have a tendency to move in a direction opposite to the water flow direction. When the water flow passes through the movable plate 5, under the action of resistance, the movable plate 5 can overcome the elastic element to move, and drive the plug 3 to move through the connecting rod 7 to realize the control of the water flow;

[0022] Specifically, a movable tube 8 is movably arranged on the inner surface of the valve body 1, and the movable plate 5 is fixedly connected to the inner surface of the movable tube 8. The outer wall of the movable tube 8 fits with the inner wall of the valve body 1, and the movement is more stable, limiting the movable plate 5 to ensure the stable position of the plug 3;

[0023] Specifically, the elastic element includes a limiting tube 9 and a limiting ring 10 arranged inside the valve body 1. The limiting tube 9 is located between the movable tube 8 and the valve, and the limiting ring 10 is fixedly connected to the inner peripheral surface of the valve body 1. The movable tube 8 is located between the limiting ring 10 and the limiting tube 9. A spring 11 is arranged between the limiting tube 9 and the movable tube 8. Under the action of the spring 11, the movable tube 8 is tightly attached to the limiting ring 10 to slide against the spring 11 under the action of the water flow;

[0024] Specifically, the limiting pipe 9 is movably connected to the valve body 1, and the limiting pipe 9 can slide along the axial direction of the valve body 1, thereby adjusting the distance between the limiting pipe 9 and the movable pipe 8. Under the action of the limiting pipe 10, the pre-tightening force of the spring 11 can be adjusted, so that the water flow can be adjusted while ensuring the self-regulation of the water flow;

[0025] Specifically, an adjusting ring 12 is movably arranged outside the valve body 1, and the adjusting ring 12 is coaxially arranged with the valve body 1. A waist-shaped hole 13 is penetrated through the side wall of the valve body 1 corresponding to the limiting pipe 9. The adjusting ring 12 and the limiting pipe 9 are fixed by a connecting block 14 slidably arranged inside the waist-shaped hole 13. The limiting pipe 9 can be driven to slide synchronously by the adjusting ring 12. To ensure the sealing performance, as Figure 2 shown, sealing gaskets are arranged on the outer peripheral surfaces of both ends of the limiting pipe 9. During the movement of the limiting pipe 9, the waist-shaped hole 13 is always located between the two sealing gaskets to prevent the irrigation water from leaking through the waist-shaped hole 13;

[0026] Specifically, an outer shell 15 is fixedly connected to the outside of the valve body 1, the adjusting ring 12 is movably arranged inside the outer shell 15, an adjusting screw 16 screwed to the adjusting ring 12 is rotatably arranged inside the outer shell 15. The number of the adjusting screws 16 is multiple and they extend in the same direction along the axial direction of the valve body 1. One end of the adjusting screw 16 is coaxially connected with an adjusting gear 17. An adjusting knob 18 is rotatably arranged at one end of the outer shell 15. The adjusting knob 18 is connected with an internal gear meshing with the adjusting gear 17. The adjusting screw 16 is controlled to rotate synchronously by the adjusting knob 18 to adjust the external adjusting ring 12. At the same time, the screw drive has a self-locking function, which is convenient for adjustment.

[0027] When the utility model is in use, the water flow passes through the valve body 1, pushes the movable plate 5 to move, and the movable plate 5 drives the plug 3 to move through the connecting rod 7. When the water flow is too large, the movable plate 5 drives the plug 3 to approach the through groove 6 to reduce the water flow. When the water flow is too small, the movable plate 5 resets under the action of the elastic element, and the plug 3 moves away from the through groove 6 to increase the water flow, realizing the self-regulation function. The adjusting knob 18 drives the adjusting gear 17 to rotate synchronously, and the adjusting gear 17 drives the adjusting screw 16 to rotate synchronously to control the movement of the adjusting ring 12 under the action of the thread fit. The adjusting ring 12 drives the limiting pipe 9 to move through the connecting block 14 to adjust the pre-tightening force of the spring 11, and further realizes the adjustment of the water flow.
