[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figures 1 to 7 The utility model embodiment is a theft-proof fast gate valve, which includes a valve body 1: a pair of flanges 2 are fixedly connected to the valve body 1, and a positioning block 3 is provided above the valve body 1, a sealing block 4 is fixedly connected to the bottom of the positioning block 3, and a pair of first bolts 5 pass through the positioning block 3, a thread groove matching the first bolt 5 is provided on the valve body 1, and a valve plate 6 is provided in the valve body 1, a limiting groove 7 is provided on the valve plate 6, a limiting block 8 is provided in the limiting groove 7, and a second bolt 9 passes through the side wall of the limiting groove 7, a thread groove matching the second bolt 9 is provided on the limiting block 8, and a rotating rod 10 is fixedly connected to the top of the limiting block 8, and the top of the rotating rod 10 passes through the sealing block 4 and the positioning block 4. Block 3 is fixedly connected with a rotating block 11, a sealing groove 12 is fixedly connected to the valve body 1, a pair of anti-theft blocks 20 pass through the sealing groove 12, and rectangular bins 13 are fixedly connected to the two side walls of the sealing groove 12, a sealing door 14 is movably connected to the rectangular bin 13, a door lock 15 is arranged on the sealing door 14, a blocking block 16 is arranged in the rectangular bin 13, the top of the blocking block 16 passes through the rectangular bin 13 and the anti-theft block 20, and a threaded rod 17 passes through the blocking block 16, a threaded groove matching the threaded rod 17 is opened on the inner wall of the rectangular bin 13, an adjusting block 18 is fixedly connected to one side of the threaded rod 17, and a special-shaped groove 19 is opened on the side wall of the adjusting block 18.

[0025] The force is evenly distributed, which improves the stability of the gate valve. A pair of flanges 2 are symmetrically arranged about the central axis of the valve body 1.

[0026] To prevent thieves from unscrewing the first bolt 5 , a pair of anti-theft blocks 20 are symmetrically arranged about the central axis of the sealing groove 12 .

[0027] In order to improve the surface friction of the rotating block 11 , anti-skid grooves are provided on the rotating block 11 .

[0028] The force is evenly distributed, thereby improving the sealing effect of the sealing block 4 . A pair of rectangular bins 13 are symmetrically arranged about the central axis of the sealing groove 12 .

[0029] The force is evenly distributed, which improves the installation stability of the positioning block 3. The pair of first bolts 5 are symmetrically arranged about the central axis of the positioning block 3.

[0030] Working principle: When the utility model is used, the gate valve is installed on the pipeline through the flange 2. When the gate valve needs to be opened, the rotating block 11 is rotated, and the rotating block 11 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the valve plate 6 to rotate until the valve plate 6 is parallel to the gate valve. During the use of the gate valve, the sealing groove 12 and the anti-theft block 20 prevent thieves from removing the first bolt 5. When the gate valve needs to be maintained, the door lock 15 is opened by the key to open the sealing door 14. At this time, a special-shaped tool is inserted into the special-shaped groove 19 to screw the adjusting block 18. The adjusting block 18 drives the threaded rod 17 to rotate until the threaded rod 17 is unscrewed, and the blocking block 16 is moved downward to keep it away from the anti-theft block 20, so that a pair of anti-theft blocks 20 can be moved away from each other. At this time, the first bolt 5 is unscrewed, and the positioning block 3 is moved upward until the valve plate 6 is taken out. When the valve plate 6 needs to be removed, the second bolt 9 is unscrewed to remove the valve plate 6.
