[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveying medium (temperature, pressure, and flow). According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, with functions such as shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems.

Slide plates 5 are sleeved near the bottom ends of the two slide rods 8. The adjacent sides of the two slide plates 5 are respectively fixedly connected with the inner walls near the centers of the left and right sides at the top end of the sleeve 4. The cross-section of the sleeve 4 is U-shaped. Internal threads matching the threaded column 6 are opened near the top end of the inner wall of the sleeve 4. First and second through holes are respectively opened near the centers of the upper and lower ends of the valve barrel 3. The sleeve 4 is respectively movably connected inside the adjacent first and second through hole cavities near the upper and lower ends. The bottom end of the sleeve 4 penetrates the second through hole cavity and is fixedly connected with a valve core 2;

[0026] Embodiment 2: A driven bevel gear 14 is movably connected to the top of the partition plate 13 near the center. A rotating shaft 12 is fixedly connected to the bottom of the driven bevel gear 14 near the center. An activity hole is formed in the inner cavity of the partition plate 13 near the center. The bottom end of the rotating shaft 12 penetrates the inner cavity of the activity hole and is fixedly connected to the top of the threaded column 6 near the center. There is a driving bevel gear 15 near the right side of the top of the driven bevel gear 14. The driving bevel gear 15 meshes with the driven bevel gear 14. A rotating rod 16 is fixedly connected to the right side of the driving bevel gear 15 near the center. The right end of the rotating rod 16 is movably connected to the inner wall of the right side of the valve sleeve 7 near the center of the top end. A coupling shaft is fixedly connected to the right end of the rotating rod 16 near the center. A first rotating hole is formed in the right side of the valve sleeve 7 near the center of the top end. The right end of the coupling shaft penetrates the inner cavity of the first rotating hole and is fixedly connected to a rotating handle 17, which is convenient for driving the threaded column 6 to rotate;

[0027] On the inner walls of the left and right sides of the valve barrel 3 near the center of the front side, a guide rod 10 is fixedly connected. Guide sleeves 9 are sleeved on both ends of the guide rod 10 near the left and right ends. Connecting rods 18 are fixedly connected to the front sides of the two guide sleeves 9 near the center. The front ends of the two connecting rods 18 are fixedly connected to the front sides of the adjacent limiting plates 11 near the center, which is convenient for limiting the positions of the two limiting plates 11, so that the two limiting plates 11 can smoothly move closer to or away from the adjacent side.

[0028] Working principle: When the water conservancy valve assembly needs to be opened or closed, first, the staff rotates the handle 17 in the reverse direction to drive the rotating rod 16 to rotate in the reverse direction. The reverse rotation of the rotating rod 16 drives the driving bevel gear 15 to rotate in the reverse direction. When the driving bevel gear 15 rotates, it meshes with the driven bevel gear 14, causing the driven bevel gear 14 to drive the rotating shaft 12 to rotate in the reverse direction. The reverse rotation of the rotating shaft 12 drives the threaded column 6 to rotate in the reverse direction, causing the threaded column 6 to drive the sleeve 4 to move upward. The upward movement of the sleeve 4 drives the two sliding plates 5 to slide upward on the two sliding rods 8, enabling the sleeve 4 to smoothly pull the valve core 2 upward and pull the valve core 2 into the inner cavity of the valve barrel 3, thereby opening the valve body 1 for water flow. When the water conservancy valve assembly needs to be closed, only rotate the handle 17 in the forward direction. Thus, for the water conservancy valve assembly with an anti-rotation structure, by conveniently driving the threaded column 6 to rotate forward or backward, the threaded column 6 can drive the sleeve 4 to move downward or upward, facilitating the sleeve 4 to push the valve core 2 into the inner cavity of the valve body 1 or pull the valve core 2 out of the inner cavity of the valve body 1, so as to quickly close or open the valve body 1 and quickly complete the opening and closing of the water conservancy valve assembly, facilitating the rapid use of the water conservancy valve assembly for water flow work. When the water conservancy valve assembly is in the closed state, the staff rotates the handle 23 in the forward direction to drive the right threaded rod 20 to rotate in the forward direction. The forward rotation of the right threaded rod 20 drives the fixed shaft 21 to rotate in the forward direction, causing the fixed shaft 21 to drive the left threaded rod 20 to rotate in the forward direction. Since the thread tapping directions of the two threaded rods 20 are opposite, the two threaded rods 20 drive the two screw sleeves 19 to move towards the adjacent side, pulling the two limit plates 11 to move towards the adjacent side. During the movement of the two limit plates 11 towards the adjacent side, the two guide sleeves 9 slide on the guide rods 10 towards the adjacent side to limit the positions of the two limit plates 11, enabling the two limit plates 11 to smoothly move towards the adjacent side and fixedly connect the inner cavity of the circular card slot near the center of the sleeve 4, thereby fixing the position of the sleeve 4 and preventing the threaded column 6 from rotating by mistake and causing the sleeve 4 to move up and down. Thus, for the water conservancy valve assembly with an anti-rotation structure, by conveniently driving the two screw sleeves 19 to move towards the adjacent side, it is convenient for the two screw sleeves 19 to smoothly drive the two limit plates 11 to approach each other, facilitating the two limit plates 11 to quickly fix the sleeve 4 in the inner cavities of the two circular card slots, thereby fixing the position of the sleeve 4 and preventing the threaded column 6 from rotating by mistake and causing the sleeve 4 to move up and down, increasing the use safety and preventing resource waste. The above is the entire working process of the present utility model.

[0029] The above embodiments are only the preferred embodiments of the present utility model and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
