[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves and regulating valves. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief.

[0004] However, there are still some problems. Although the trigger end is fitted with the pressure sensor by the upward displacement of the float plate, thereby blocking the water inlet and outlet, the water level position where the valve body needs to be closed cannot be adjusted according to usage requirements. The valve body can only be closed when the water level reaches the height that pushes the float plate to contact the sensor. There are certain limitations, so an automated adjustable valve body is proposed to solve the above problems. Utility Model Content

[0024] In addition, the outer surface of the telescopic rod 5 is rotatably connected to a limit block 8, the length of the limit block 8 is greater than the length of the button 4, and after the limit block 8 is rotated, the limit block 8 will be located at the bottom of the valve body 1, so that the pressing plate 3 cannot contact the button 4, and a sealing component is provided on the top of the valve body 1, and the sealing component is used to close the valve body 1, and the sealing component includes a motor 9 fixed to the valve body 1, and the output shaft of the motor 9 is fixed with a driving rod 10 that penetrates into the interior of the valve body 1, and the outer surface of the driving rod 10 is threadedly connected with a sealing plate 11, and the driving A threaded strip is fixed on the outer surface of the rod 10, and a threaded hole matching the threaded strip is provided on the top of the sealing plate 11. The sealing plate 11 is a square plate. A square groove slidably connected to the sealing plate 11 is provided inside the valve body 1. The rotation of the sealing plate 11 can be effectively restricted by the provided square groove, so that the sealing plate 11 will move due to the extrusion of the thread. An outlet pipe 12 is fixed on the left side of the valve body 1, and a water inlet pipe 13 is fixed on the top of the valve body 1. The inner cavities of the valve body 1, the outlet pipe 12 and the inlet pipe 13 are connected to each other.

The opposite sides of the two clamping rods 704 and the interior of the moving block 702 are both provided with inclined surfaces. Through the provided inclined surfaces, when the moving block 702 moves downward, the clamping rod 704 is squeezed, so that the clamping block 705 clamps the telescopic rod 5, so that the length of the telescopic rod 5 is fixed.

[0028] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0029] The working principle of the above embodiment is:

[0030] When the water level rises, the water surface will contact the floating plate 6. Under the action of buoyancy, the floating plate 6 will rise with the water level, so that the telescopic rod 5 drives the pressing plate 3 to move. When the water level reaches the required water level, the pressing plate 3 just presses the button 4, so that the button 4 starts the motor 9 through an electrical signal, drives the driving rod 10 to rotate, and makes the sealing plate 11 that cannot rotate move due to the extrusion of the thread, and closes the valve body 1, thereby achieving the purpose of automatic closing. By rotating the rotating block 701, the rotating block 701 drives the moving block 702 to move upward due to the extrusion of the thread, so that the moving block 702 is away from the clamping rod 704, so that the clamping rod 704 and the clamping block 705 lose the extrusion on the telescopic rod 5, so that the telescopic rod 5 can be adjusted in length to drive the floating plate 6 to move, so that the position of the required water level can be adjusted, effectively improving the overall practicality.
