Compared with the traditional detachable filter screen, the hemispherical filter screen 5 realizes intelligent self-cleaning, and there is no need to frequently disassemble and install the filter screen, thereby reducing labor costs and improving water delivery efficiency. It avoids the wear of the valve caused by frequent manual disassembly of the filter screen, thereby improving the reliability and service life of the intelligent valve; according to the required water flow, the spiral cylinder 6 rotates upward under the action of the spiral ring 16, the key cylinder 20 moves upward to squeeze the second spring 22, and the spiral cylinder 6 moves to lift the ball head 31. At this time, the threaded ring 7 follows the spiral cylinder 6 to move upward , the threaded ring 7 moves upward with the slider 9 in the slide groove 8 to compress the first spring 15, and the threaded ring 7 moves upward with the sealing plate 27 and the hemispherical valve 13. At this time, the hemispherical valve 13 is separated from the water inlet pipe 2, and the water inlet pipe 2 is slowly opened. The water flow of the intelligent valve is controlled according to the distance of the upward movement of the hemispherical valve 13; during the long-term filtration process of the hemispherical filter 5, the hemispherical filter 5 will be blocked, which will lead to a decrease in the water flow in the outlet pipe 3. At this time, when the flow sensor 25 detects a decrease in water flow, it transmits a signal to the controller 26. The controller 26 executes a cleaning command for the hemispherical filter 5, and the electromagnetic valve 19 rotates to open the sewage pipe 4. The motor 24 provides a power source, and the hemispherical filter 5 is intelligently self-cleaned through the rotation angle of the hemispherical filter 5 and the direction of the water flow, and the valve body 1 integrates cutoff, filtration, and intelligence. ,
