Abstract
Description
Technical Field
[0001] This utility model relates to the field of five-way ball valve technology, and more specifically, it relates to an electrically controlled five-way ball valve for irrigation. Background Technology
[0002] A five-way ball valve is a multi-channel fluid control valve that switches between multiple flow paths by rotating a ball. It is widely used in industrial scenarios such as chemical, pharmaceutical, and food processing where multiple media switching is required. The valve body of a five-way ball valve is usually made of stainless steel. The types of drive methods can be divided into manual, pneumatic, electric, and hydraulic. In some agricultural fields, five-way ball valves are also needed, such as in irrigation, where they are used to switch between multiple water channels to deliver water to different fields, thereby making the irrigation system more flexible and automated.
[0003] Traditional electrically controlled five-way ball valves mostly have fixed connecting pipes. When connecting to external water pipes, if the distance is too far to reach, the water pipe needs to be extended by connecting pipes. However, connecting pipes is not only more troublesome to operate, but also prone to leakage, affecting normal use.
[0004] Most existing electrically controlled five-way ball valves are controlled by a motor during use. Since water flows inside the ball valve, it inevitably impacts the ball that controls the water flow direction. Over time, the motor's self-locking structure will be affected, thus affecting its service life. Utility Model Content

[0030] Please see Figure 1-5 An electrically controlled five-way ball valve for irrigation includes a valve body 1. The valve body 1 has a spherical cavity inside, and a control ball 2 is rotatably mounted inside the cavity. Flow ports 3 are provided on the outer wall and bottom of the control ball 2, and the two flow ports 3 are connected. Water guide pipes 4 are fixedly mounted on the outer wall of the valve body 1 in four directions. External connecting pipes 5 are slidably mounted on the outer ends of the water guide pipes 4. One end of each external connecting pipe 5 has a telescopic pipe 6. A connecting ring 7 is provided on the outer wall of each water guide pipe 4. The other end of each telescopic pipe 6 is fixedly connected to the connecting ring 7. Threaded posts 8 are provided on both sides of the outer wall of the connecting ring 7. Fixing blocks 9 are provided on both sides of the outer wall of the external connecting pipe 5. The fixing blocks 9 are movably mounted to the threaded posts 8. Adjusting nuts 10 are provided on each threaded post 8. Two sets of adjusting nuts 10 are provided, both contacting the fixing blocks 9. A control rod 11 is fixedly mounted on the upper end of the control ball 2. The inner wall of the external connecting pipe 5 is in close contact with the outer wall of the water guide pipe 4.
[0031] In this embodiment, the control rod 11 is rotatably mounted to the valve body 1 via a sealed bearing. A support 12 is fixedly provided on the upper end face of the valve body 1. Support frames 13 are provided on both sides of the upper end face of the support 12. A motor 14 is provided on the upper end face of the support frame 13. The output end of the motor 14 is fixedly connected to the control rod 11. Electric push rods 15 are fixedly provided on both the upper end face of the support 12 and on both the front and rear sides. A clamping block 16 is provided on the output end of each electric push rod 15. Anti-slip textures 17 are provided on the outer wall of both the clamping block 16 and the control rod 11.
[0032] More specifically, when connecting to an external water supply pipe, the user can adjust the installation position of the ball valve on the threaded post 8 by rotating the adjusting nut 10. Then, the extension length of the external pipe 5 can be adjusted by the telescopic tube 6, so that the ball valve can be connected to external water supply pipes of different lengths, increasing the flexibility of use. When switching water circuits, the control rod 11 can be driven by the motor 14 to rotate the control ball 2 to adjust the orientation angle of the flow port 3. Then, the electric push rod 15 can be controlled to move the clamp 16 so that the anti-slip texture 17 on the clamp 16 abuts against the anti-slip texture 17 on the control rod 11, thereby fixing the control rod 11 to prevent the control ball 2 from rotating due to water erosion, which would affect the service life of the motor 14.
[0033] Please see Figures 1-3 As an embodiment for disassembling and assembling the annular ring 20: a water inlet pipe 18 is fixedly provided on the lower end face of the valve body 1. An annular groove 19 is provided inside the water inlet pipe 18. An annular ring 20 is movably provided inside the annular groove 19. A filter screen 21 is provided inside the annular ring 20. Mounting posts 22 are provided on the inner wall of the annular groove 19 on both sides. The annular ring 20 is movably installed with the mounting posts 22. Each mounting post 22 is provided with a clamping nut 23. The clamping nut 23 is threadedly connected to the mounting post 22. A flange 24 is provided at the bottom of the water inlet pipe 18.
[0034] Specifically, by setting up the filter screen 21, the groundwater can be filtered to prevent impurities inside from entering the valve body 1 and blocking the flow port 3 on the control ball 2, thus affecting normal use. Subsequently, the ring 20 can be disassembled by removing the clamping nut 23 to facilitate cleaning the residue on the filter screen 21 and to facilitate continued use.
[0035] Please refer to Figure 2 As a further embodiment of the method of guiding water through the water pipe 4: the inner diameter of the flow port 3 is equal to the inner diameter of the water pipe 4.
[0036] Specifically, the flow port 3 allows water to flow into guide pipes 4 in different directions, thereby enabling the switching of water paths.
[0037] In summary, when using the entire device: the control lever 11 is rotated by controlling the motor 14 to adjust the orientation angle of the flow port 3 by rotating the control ball 2; then, the electric push rod 15 is controlled to move the clamping block 16 so that the anti-slip texture 17 on the clamping block 16 abuts against the anti-slip texture 17 on the control lever 11, thereby fixing the control lever 11 and preventing the control ball 2 from rotating due to water erosion, which would affect the service life of the motor 14. When connecting to an external water supply pipe, the user can adjust the mounting position on the threaded post 8 by rotating the adjusting nut 10. After adjustment, the extension length of the external pipe 5 can be adjusted through the telescopic pipe 6, so that the ball valve can be connected to external water supply pipes of different lengths, increasing the flexibility of the device during use. In addition, a filter screen 21 is installed inside the water inlet pipe 18 to filter the groundwater, so as to prevent impurities inside from entering the valve body 1 during irrigation and blocking the flow port 3 on the control ball 2, affecting normal use. Subsequently, the ring ring 20 can be disassembled by removing the clamping nut 23 to facilitate the cleaning of residues on the filter screen 21 for continued use.
