[0022] Reference Figures 1-7 A solenoid valve assembly with a small flow channel spacing includes: a valve body 11, a movable cavity 14 disposed within the valve body 11, a connecting cavity 16 disposed within the left end wall of the movable cavity 14, a second sealing ring 17 fixedly connected to the left end wall of the connecting cavity 16, a sealing cavity 18 disposed within the second sealing ring 17, a flow channel block 20 fixedly connected to the left end face of the valve body 11, a flow channel cavity disposed within the flow channel block 20, and a partition plate 19 fixedly connected to the flow channel block 20. The movable cavity 14 and the sealing cavity 18 are both open to the left and right. The connecting cavity 16 communicates with the movable cavity 14 and the sealing cavity 18. The partition plate 19 divides the flow channel cavity into two vertically parallel second flow channels 22 and 23. The first flow channel 21, the second flow channel 22, and the first flow channel 21 are all open on the left and right sides. The second flow channel 22 is connected to the sealing cavity 18, and the first flow channel 21 is connected to the connecting cavity 16. A valve core mechanism 30 is provided inside the valve body 11 and on the right side of the valve body 11. The valve core mechanism 30 can block the connecting cavity 16 and the sealing cavity 18. At this time, the second flow channel 22 and the first flow channel 21 are disconnected. When the valve core mechanism 30 is activated, it can connect the connecting cavity 16 and the sealing cavity 18. At this time, the second flow channel 22 and the first flow channel 21 are connected through the sealing cavity 18 and the connecting cavity 16, allowing water to flow normally and realizing the opening and closing operation.

[0023] The outer right side of the second sealing ring 17 is chamfered to facilitate the sliding connection between the valve core mechanism 30 and the sealing cavity 18, thereby connecting and disconnecting the connecting cavity 16 from the sealing cavity 18.

[0024] The first sealing ring 15 is fixedly connected to the left end wall of the movable cavity 14. The first sealing ring 15 is used to connect and cooperate with the valve core mechanism 30 to seal and prevent water leakage.

[0025] The connecting ring 23 is fixedly connected to the outer wall of the first flow channel 21 or the second flow channel 22, wherein the connecting ring 23 is used to connect the water flow pipe or the water flow inlet and outlet.

[0026] The mounting ring 12 is fixedly connected to the left outer side wall of the valve body 11. Multiple mounting holes 13 are provided in the mounting ring 12, wherein the mounting holes 13 are used to install and fix the valve body 11.

[0027] A fixing hole 27 is provided on the right side of the valve body 11, wherein the fixing hole 27 is used to install and fix the valve core mechanism 30.

[0028] The valve core mechanism 30 includes: The electromagnetic actuator 24 is fixed to the valve body 11. The moving iron core 32 is fixedly connected to the left end of the electromagnetic actuator 24. The main piston 25 is slidably connected to the connecting cavity 16. The sealing plug 28 is fixedly connected to the electromagnetic actuator 24. The intermediate cavity 29 is formed between the main piston 25 and the sealing plug 28. The small valve port 26 is fixedly connected to the main piston 25. The connecting port 31 is fixedly connected to the main piston 25. The sealing plug 28 is slidably connected to the movable cavity 14. The connecting port 31 connects the connecting cavity 16 and the intermediate cavity 29. The bolt enters the fixing hole 27 and is fixed to the valve body 11, thus fixing the electromagnetic actuator 24 to the valve body 11. The left side of the main piston 25 has a groove that slides with the second sealing ring 17. The left side of the small valve port 26 has a groove that slides with the second sealing ring 17. The right opening connects the sealing cavity 18 and the intermediate cavity 29. When the main piston 25 and the moving iron core 32 are pushed to the leftmost position by the push rod of the electromagnetic pusher 24, the moving iron core 32 can seal the small valve port 26. At this time, the intermediate cavity 29 is not connected to the sealing cavity 18. When the moving iron core 32 is pulled to the rightmost position by the push rod of the electromagnetic pusher 24, the intermediate cavity 29 is connected to the sealing cavity 18. Since the connecting port 31 connects the connecting cavity 16 and the intermediate cavity 29, the first flow channel 21 is connected to the second flow channel 22. Water flows into the sealing cavity 18 and then pushes the main piston 25 to the right through the pressure difference at both ends of the main piston 25, thereby directly connecting the connecting cavity 16 and the sealing cavity 18, and starting a large flow of water.

[0029] Work or installation process: In use, the electromagnetic push rod 24 and the valve body 11 are connected and fixed. The first flow channel 21 and the second flow channel 22 are connected to the corresponding inlet and outlet water ports or inlet and outlet water pipes in the equipment where the electromagnetic valve is installed through the connecting ring 23. The valve body 11 is installed and fixed on the equipment where the electromagnetic valve is installed through the mounting hole 13. At this time, the small valve port 26 is sealed by the passive iron core 32, the main piston 25 is located at the leftmost movable position, separating the sealing cavity 18 and the connecting cavity 16, the second flow channel 22 and the first flow channel 21 are not connected and activated, and the electromagnetic push rod 24 is connected to the power supply. When it is necessary to connect the first flow channel 21 and the second flow channel 22, the electromagnetic pusher 24 is activated to retract and move the pusher to the right, thereby driving the moving iron core 32 to move to the right, so that the small valve port 26 is connected. At this time, the first flow channel 21 and the second flow channel 22 are connected through the connecting cavity 16 and the sealing cavity 18. Water flows into the sealing cavity 18, and then the pressure difference between the two ends of the main piston 25 pushes the main piston 25 to move to the right, thereby directly connecting the connecting cavity 16 and the sealing cavity 18, starting a large flow of water and realizing the opening and closing function. Since the first flow channel 21 and the second flow channel 22 are parallel to each other and separated by the partition plate 19, the distance between the first flow channel 21 and the second flow channel 22 is small, occupying little internal space in the equipment where the solenoid valve is installed.
