Technical Field

[0001] The utility model belongs to the technical field of gate valves, in particular to a lifting gate valve. Background Art

[0002] A lift gate valve is a special type of gate valve in which the valve stem is connected to the valve plate and rises and falls as the valve opens and closes. When the valve is opened, the valve stem rises, allowing the valve plate to completely lift off the seat, allowing for a smooth passage of fluid. When the valve is closed, the valve stem descends, pressing the valve plate against the seat, achieving a sealed state.

[0003] Patent application number: 202320154495.8 discloses a lifting gate valve with a filtering structure, including a valve body, a tube body is connected to the center of both sides of the inner wall of the valve body, a through pipe is connected to the top of the inner wall of the tube body, a filter ring is connected to the bottom of the through pipe, a filter element is connected to the bottom end of the inner wall of the through pipe, a top pipe is connected to the top of the inner wall of the through pipe, a filter screen is connected to the bottom end of the inner wall of the top pipe, a valve frame is fixedly connected to the top of the valve body, and plugs are connected to both ends of the transverse symmetry axis of the top of the valve frame, and the top of the plug is connected to the filter element. The inner wall at the center of the part is connected with bolts, the outer wall of the plug column is connected with a top cover, the inner wall center of the top cover is fixedly connected with a shaft ring, the inner wall of the shaft ring is connected with a shaft rod, the bottom of the shaft rod is connected with a threaded column, the outer wall of the threaded column is connected with a gate plate, and the outer wall of the gate plate is connected with a rubber sleeve; by setting a filter element, fine particles mixed in the water flow can be filtered, and by setting a filter net, garbage or soil mixed in the water flow can be filtered, thereby preventing garbage or soil from adhering to the gate plate, causing the gate plate to fail to open and close normally.

[0004] In the current existing technology, although the above scheme can filter garbage or soil mixed in the water flow, after the threaded column is adjusted, since there is no self-locking structure between the threaded column and the gate plate, the threaded column will deflect when the gate valve is closed, causing water to leak out, which will cause trouble.

[0005] Therefore, a lifting gate valve is proposed to solve the above problems. Utility Model Content

[0013] Beneficial effects of the utility model:

[0014] The utility model provides a lifting gate valve. When the gate valve needs to be adjusted by rotating the turntable, the user dials the No. 1 dial block downward, and the No. 1 dial block drives the stop block to slide into the No. 1 shell. After the stop block enters the No. 1 shell, the stop rod is rotated to the top of the stop block. At this time, the stop block is fixed, and the turntable loses its fixation, so the turntable can be rotated to adjust the gate valve. After the gate valve is adjusted, the No. 1 dial block is held and the stop rod is rotated to make the stop rod away from the stop block. Because in the process of the stop block sliding into the No. 1 shell, the stop block will squeeze the No. 1 spring, and the No. 1 spring will shrink due to the squeezing, and will give the stop block a thrust. Therefore, after the stop rod is away from the stop block, the No. 1 dial block is slowly released. Under the action of the thrust of the No. 1 spring, the stop block slides out of the No. 1 shell and fixes the turntable, so that the screw rod will not deflect and water will not flow out.

[0028] During operation, when it is necessary to rotate the turntable 15 to adjust the gate valve, the user dials the No. 1 dial block 23 downward, and the No. 1 dial block 23 drives the block 21 to slide into the No. 1 housing 2. After the block 21 enters the No. 1 housing 2, the stopper 27 is rotated to the top of the block 21. At this time, the block 21 is fixed, and the turntable 15 loses its fixation. The turntable 15 can be rotated to adjust the gate valve. After the gate valve is adjusted, hold the No. 1 dial block 23 and rotate the stopper 27 so that the stopper 27 Keep away from the block 21, because when the block 21 slides into the No. 1 shell 2, the block 21 will squeeze the No. 1 spring 22, and the No. 1 spring 22 will shrink under the squeezing and give a thrust to the block 21. Therefore, after the stop rod 27 is away from the block 21, slowly release the No. 1 shift block 23.

The turntable 15 can be rotated to adjust the gate valve. After the gate valve is adjusted, hold the No. 1 dial block 23 and rotate the stopper 27 to make the stopper 27 away from the The stopper 21, because when the stopper 21 slides into the No. 1 housing 2, the stopper 21 will squeeze the No. 1 spring 22, and the No. 1 spring 22 will shrink under the squeezing, and will give a thrust to the stopper 21, so after the stopper 27 is away from the stopper 21, the No. 1 shifter 23 is slowly released, and under the action of the thrust of the No. 1 spring 22, the stopper 21 slides out of the No. 1 housing 2 and fixes the turntable 15, so that the screw 14 will not deflect and water will not flow out;

[0039] When the gate valve needs to be adjusted, the user pinches the two No. 2 dial blocks 35 at the same time to make the two No. 2 dial blocks 35 approach each other, and at the same time drives the plug block 33 to slide into the No. 2 outer shell 31 and slide out from the positioning shell 34. After the plug block 33 slides out of the positioning shell 34, the protection box 3 loses its fixation, and the protection box 3 is taken down from the top cover 16, and the turntable 15 can be rotated to adjust the gate valve; after the gate valve is adjusted, the two No. 2 dial blocks 35 are pinched again to make the plug block 33 slide into the No. 2 outer shell 31. In the shell 31, during the sliding of the slider, the No. 2 spring 32 will be squeezed, the No. 2 spring 32 will shrink under the squeezing, and will give a thrust to the plug 33. After pinching the No. 2 block 35, the protection box 3 is placed above the top cover 16, and the plug 33 is aligned with the position of the positioning shell 34. After alignment, slowly release the No. 2 block 35.
