[0026] When the gate valve body 1 is opened, the valve plate 12 rises, and the pressurized water flow will flow through the slots in the arc-shaped filter screen 21, and the pressure generated on the arc-shaped filter screen 21 will prompt the slider 22 to slide on the outer surface of the slide rod 23 and squeeze the spring 24, thereby blocking the impact force of the water flow on the sealing ring 11, avoiding wear of the sealing ring 11 after long-term use, and improving the sealing effect of the sealing ring 11. When the gate valve body 1 is closed, the valve plate 12 slides in the groove 102, and at the same time, the water in the groove 102 is discharged from the through groove 121 through the downward pressure of the valve plate 12, thereby closing the valve plate 12.
