[0025] Working principle: When the solenoid valve is used for irrigation, the user aligns the locking pin 5 on the filter element 4 with the slide groove 8 on the inner wall of the filter block 3, presses the cover plate 9 downward, the locking pin 5 slides in the slide groove 8, and the cover plate 9 drives the filter element 4 to move. When the filter element 4 contacts the connecting plate 6, the spring 1 7 is pressed downward through the connecting plate 6. When the locking pin 5 contacts the slide groove 28, the cover plate 9 is rotated at this time, and the locking pin 5 slides in the slide groove 28. The cover plate 9 is released. Under the elastic force of the spring 1 7, the locking pin 5 will be stuck in the slide groove 3 29, and the filter element 4 is locked in the filter block 3 through the locking pin 5. Inside, the sealing ring 10 and the sealing plug 31 are used to achieve sealing. At this time, the water flow is turned on, and the water flows into the interior of the filter block 3 through the water pipe 16. The filter hole 30 on the filter element 4 is used for filtering to filter out impurities in the water. When the filter element 4 needs to be cleaned, the cover plate 9 is pressed downward and rotated in the opposite direction. At this time, the filter element 4 presses the spring 1 7 downward through the connecting plate 6. When the locking pin 5 exits the slide groove 3 29, the filter element 4 can be easily taken out under the elastic force of the spring 1 7, thereby cleaning the filter element 4 and reducing the probability of blockage of the solenoid valve. After the pipeline is connected, the handle 15 is manually turned to open the handle. 15 drives the threaded rod 12 to rotate on the fixed block 11, and the threaded rod 12 drives the locking block 14 to move from both sides to the middle on the slide rail 13. The locking block 14 is used to clamp the water pipe 16, fix the water pipe 16, and it is not easy to loosen. The solenoid valve works more smoothly. When the water flows into the water injection chamber 25 from the water inlet 24, the piston 22 is blocked above the water injection chamber 25. The partition plate 23 is used to block the flow of water. The water flows from the guide hole 26 into the cavity above the piston 22 to achieve hydraulic pressure balance. The coil 19 is energized, and the coil 19 generates magnetic force. Through the fixed iron core 18 enhances the magnetic field, thereby causing the moving iron core 21 to move upward, and the moving iron core 21 drives the piston 22 to leave from above the water injection chamber 25. At this time, the moving iron core 21 will squeeze the spring 20, and the piston 22 will move upward, the valve will open, and water will flow from the water inlet 24 through the water injection chamber 25 to the water outlet 27, and then flow out to irrigate the crops. When water is not needed, the coil 19 is powered off, and the moving iron core 21 drives the piston 22 back to its original position under the elastic force of the spring 20, and the piston 22 will seal the top of the water injection chamber 25, the valve is closed, and the water no longer flows out from the water outlet 27.
