[0001] The utility model relates to the technical field of gate valves, in particular to a thin plate type gate valve. Background Art
[0002] As we all know, gate valve is a common valve, generally including valve body, valve stem, valve cover, opening and closing gate, etc. The opening and closing gate moves in the vertical direction along the center line of the passage to realize the opening and closing function. It mainly plays the role of cutting off the flow of the transported medium in the pipeline. There are many types of gate valves, among which thin-plate gate valves are widely used.
[0003] During the use of the existing thin-plate gate valve, after the rocker opens or closes the valve to a certain state, no protective measures are added. However, in actual use, the rocker can easily rotate due to misoperation or collision, making the flow of the valve body uncontrollable, thereby reducing the control accuracy of the valve.

[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model provides a thin plate gate valve. The inner rod is held and pulled upward. The inner rod drives the clamping plate and the limit rod to move. The clamping plate moves upward with the inner rod to be away from the rocking wheel, thereby releasing the fixation of the rocking wheel. Then, the inner rod is flipped in the direction away from the rocking wheel. Then, the rocking wheel is rotated to drive the valve stem to rotate. Then, the inner rod is flipped in the direction close to the rocking wheel. At the same time, the inner rod is pulled upward. The inner rod drives the clamping plate to move to the top of the rocking wheel, so that the clamping plate is clamped on the outside of the rocking wheel. The spring applies a downward pulling force to the clamping plate, so that the clamping plate fixes the rocking wheel, thereby preventing the rocking wheel from rotating due to misoperation or collision, thereby controlling the flow of the valve body, thereby improving the control accuracy of the valve.
[0015] 2. The utility model provides a thin plate gate valve. During use, the inner rod moves within a limited track through the setting of the limit rod and the limit groove, thereby ensuring the normal operation of the components.

A spring 14 is movably sleeved on the outer edge of the outer tube 8, one end of the spring 14 is fixedly connected to the limit rod 15, and the other end of the spring 14 is fixedly connected to the second fixing ring 13.

[0028] Working principle: During use, the valve body 1 is connected to the connecting pipe through the flange 2, and the valve body 1 is closed and opened by rotating the hand wheel 5. Before rotating the hand wheel 5, first hold the inner rod 7 and pull the inner rod 7 upwards, the inner rod 7 drives the clamping plate 17 and the limit rod 15 to move, the limit rod 15 moves in the inner cavity of the limit groove 16, and the spring 14 is compressed at the same time, and the clamping plate 17 moves upward with the inner rod 7 away from the hand wheel 5 to release the fixation of the hand wheel 5, and then flip the inner rod 7 in the direction away from the hand wheel 5, the inner rod 7 drives the outer tube 8 to flip around the adjacent pin shaft 11 as the center, and then the action of the inner rod 7 is released.

The spring 14 applies a downward pulling force to the clamping plate 17, so that the clamping plate 17 fixes the rocking wheel 5, thereby preventing the rocking wheel 5 from rotating due to misoperation or collision, thereby controlling the flow of the valve body, thereby improving the control accuracy of the valve.
