Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 6The solenoid valve core sealing assembly provided by this utility model includes a valve body 1 and a valve cover 2. The valve cover 2 is disposed on the upper surface of the valve body 1. An inner cavity 3 is formed inside the valve body 1. Liquid passages 4 communicating with the inner cavity 3 are formed at both ends of the valve body 1. A retaining ring 5 is fixedly installed on the inner wall of the inner cavity 3. A threaded rod 6 is rotatably connected to the upper surface of the valve cover 2. The threaded rod 6 penetrates the upper surface of the valve cover 2 and extends into the inner cavity 3. An electromagnetic head 7 is provided at the top of the threaded rod 6. A valve core body 8 is disposed inside the inner cavity 3. The upper surface of the valve core body 8 is fixedly... A sleeve 9 is fixedly installed, and the inner wall of the sleeve 9 has a threaded groove that meshes with the threaded rod 6. A slider 10 is fixedly installed on the outer surface of the valve core body 8. A sliding groove that matches the slider 10 is opened on the inner wall of the inner cavity 3. A sealing sleeve 11 is fitted on the outer surface of the valve core body 8. Several positioning rods 12 are fixedly installed on the upper surface of the valve core body 8. The upper surface of the sealing sleeve 11 has positioning holes that are the same in number and position as the positioning rods 12. The positioning rods 12 are inserted into the positioning holes. The outer surface of the bottom end of the sealing sleeve 11 is in contact with the inner ring of the retaining ring 5.

[0031] To facilitate the removal of the valve core body 8 from the valve body 1, a sealing gasket 13 is provided on the upper surface of the valve body 1. Six limiting rods 14 are fixedly installed on the lower surface of the sealing gasket 13. The limiting rods 14 are inserted into the upper surface of the valve body 1. Six positioning pins 15 are fixedly installed on the upper surface of the valve body 1. The positioning pins 15 penetrate the sealing gasket 13 and the lower surface of the valve cover 2. Nuts 16 are threadedly connected to the outer surface of the top of the positioning pins 15. The nuts 16 abut against the valve cover 2.

[0032] By configuring the valve body 1, valve cover 2, inner cavity 3, fluid passage 4, retaining ring 5, threaded rod 6, solenoid head 7, valve core body 8, sleeve 9, slider 10, sealing sleeve 11, positioning rod 12, sealing gasket 13, limit rod 14, positioning pin 15, and nut 16, the function of quickly and conveniently replacing the sealing sleeve 11 is realized. This improves the installation method of the sealing sleeve 11 in the existing technology, so that when the sealing sleeve 11 is damaged, it can be quickly replaced, saving time and effort and improving the practicality of the solenoid valve.

[0033] The upper surface of the valve cover 2 is provided with a connecting assembly, which includes a rotating cylinder 17 and a limiting block 18. The rotating cylinder 17 is rotatably connected to the lower surface of the solenoid head 7. The limiting block 18 is fixedly installed on the outer surface of the top end of the threaded rod 6. The top end of the threaded rod 6 is inserted into the rotating cylinder 17. The inner wall of the rotating cylinder 17 is provided with a limiting groove that matches the limiting block 18. Two connecting blocks 19 are fixedly installed on the lower surface of the solenoid head 7. Two mounting blocks 20 are fixedly installed on the upper surface of the valve cover 2. A positioning block 21 is fixedly installed on the side wall of the connecting block 19. The two connecting blocks 19 are respectively attached to the corresponding mounting blocks 20. The side wall of the mounting block 20 is provided with a positioning groove that matches the positioning block 21. A fixing bolt 22 is threadedly connected to the side wall of the mounting block 20. The fixing bolt 22 passes through the side wall of the mounting block 20 and is inserted into the side wall of the connecting block 19.

[0034] By setting up a rotating drum 17, a limiting block 18, a connecting block 19, a mounting block 20, a positioning block 21, and a fixing bolt 22, the function of quickly installing and removing the solenoid head 7 is realized, which improves the installation method of the solenoid head 7 in the existing technology. When the solenoid head 7 is damaged, it can be quickly removed from the valve cover 2, making it more convenient to repair or replace the solenoid head 7. On the original basis, the practicality of the solenoid valve is further improved.

[0035] Working principle: When using the solenoid valve, pipes are connected to both ends of the valve body 1, one of which is connected to a water source. When using the solenoid valve, the solenoid head 7 is activated. When the solenoid head 7 is running, the rotating drum 17 rotates. During the rotation of the rotating drum 17, the threaded rod 6 rotates inside the inner cavity 3. When the threaded rod 6 rotates, it drives the sleeve 9 to move through the threaded groove. Under the action of the valve core body 8 and the slider 10, the sleeve 9 rises or falls along the outer surface of the threaded rod 6, thereby driving the valve core body 8 and the sealing sleeve 11 to slide up or down along the inner wall of the inner cavity 3. When the valve core body 8 and the sealing sleeve 11 are inserted into the inner ring of the retaining ring 5, the outer surface of the sealing sleeve 11 and the outer surface of the retaining ring 5 are in contact with each other, blocking the two liquid passages 4, thereby cutting off the water flow. Conversely, the two liquid passages 4 are unobstructed.

[0036] When replacing the sealing sleeve 11, first tighten the nut 16 to disengage it from the outer surface of the positioning post 15. After unscrewing all the nuts 16 from the positioning post 15, pull the valve cover 2 upwards to move it away from the valve body 1. This causes the threaded rod 6 to drive the sleeve 9, valve core body 8, and sealing sleeve 11 to slide upwards. The slider 10 slides inside the groove. After the sleeve 9, valve core body 8, and sealing sleeve 11 slide out of the inner cavity 3, pull the two ends of the upper surface of the sealing sleeve 11 to disengage the positioning rod 12 from the sealing sleeve 11. Then remove the sealing sleeve 11 from the valve core body 8. Next, take out the new sealing sleeve 11 and repeat the above operations in reverse to complete the replacement of the sealing sleeve 11.

[0037] When repairing or replacing the solenoid head 7, loosen the two fixing bolts 22 so that both bolts 22 extend away from the mounting block 20. After the mounting block 20 separates from the connecting block 19, the restriction on the connecting block 19 is released, thereby releasing the fixation of the solenoid head 7. Then, pull the solenoid head 7 upward so that the connecting block 19 slides upward against the mounting block 20, the positioning block 21 slides inside the positioning groove, and at the same time, the rotating cylinder 17 slides upward at the top of the threaded rod 6, and the limiting block 18 slides inside the limiting groove. After the connecting block 19 separates from the mounting block 20, the rotating cylinder 17 separates from the threaded rod 6, completing the disassembly of the solenoid head 7. At this time, the solenoid head 7 can be repaired or replaced. After the solenoid head 7 is repaired or replaced, reverse the above operation and reinstall the solenoid head 7 onto the valve cover 2.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
