[0029] Working principle: When the gate valve is needed, the sealing groove 7 is used to seal the valve cover 3 and the storage column 2 to prevent water from leaking out from the gap between the valve cover 3 and the storage column 2. The second sealing ring 6 can make the valve core 11 and the connecting pipe 1 fit more tightly, thereby preventing water from flowing out from between the valve core 11 and the connecting pipe 1, thereby achieving a good sealing effect and avoiding water leakage and waste. The hand wheel 8 can then be turned to drive the valve stem 9 to slide on the inner wall of the valve cover 3, thereby driving the valve stem 9 to rise and fall. When the valve stem 9 rises and falls, it can drive the valve core 11 to rise and fall on the inner wall of the connecting pipe 1, thereby adjusting the water flow. At this time, the hand wheel 8 can be used to drive the valve stem 9 to slide on the inner wall of the valve cover 3, thereby driving the valve stem 9 to rise and fall. When the valve stem 9 rises and falls, it can drive the valve core 11 to rise and fall on the inner wall of the connecting pipe 1, thereby adjusting the water flow.

When the sliding column 12 slides, it will drive the sliding plate 14 to slide on the inner walls of the storage groove 16 and the card groove 19. When the sliding plate 14 slides, it can drive the card column 18 to slide on the inner wall of the card groove 19. At the same time, the sliding plate 14 will squeeze the spring 15, so that the spring 15 can slide on the inner wall of the hollow column 17. At this time, the connecting column 10 and the valve core 11 are no longer fitted, so that the valve core 11 can be quickly disassembled for easy maintenance. The gate valve can not only achieve a good sealing effect and avoid water leakage and waste, but also achieve the effect of quickly disassembling the valve core 11 for easy maintenance.
