[0022] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Reference Figures 1-4 An electrically operated valve includes a valve body 10. An auxiliary mechanism is provided on the top of the valve body 10. The auxiliary mechanism includes an alarm 8, an extension bar 12, and a power failure protector 14. A valve stem 5 is fixedly connected to one side of the extension bar 12. The valve stem 5 passes through the top side wall of the valve body 10 and is rotatably connected to the valve body 10. A support base 20 is inserted into the top of the valve stem 5. A limit rod 19 is fixedly connected to the bottom of the support base 20. The bottom of the limit rod 19 is inserted into the extension bar 12. A support plate 13 is fixedly connected to the top of the support base 20. An electrical control box 9 is engaged with the top of the support plate 13. An alarm 8 is fixedly connected to the top of the electrical control box 9. The alarm 8 is electrically connected to the power failure protector 14. The bottom of the power failure protector 14 is fixedly connected to the support plate 13.

[0024] A limiting block 16 is slidably connected to the top of the support plate 13. A heat dissipation fin 17 is fixedly connected to one side of the limiting block 16, and a bolt is installed between the limiting block 16 and the support plate 13. One side of the limiting block 16 overlaps with the electrical control box 9. Three heat dissipation pipes 18 are embedded inside the support plate 13. The ends of the heat dissipation pipes 18 penetrate the top side wall of the support plate 13, and the three heat dissipation pipes 18 are connected to each other through a branch pipe 21. A cooling fan 15 is fixedly connected to the top of the middle heat dissipation pipe 18, and the bottom of the cooling fan 15 is fixedly connected to the support plate 13.

[0025] Specifically, by rotating the valve stem 5, the position of the valve core inside the valve body 10 can be adjusted, thereby achieving the adjustment of the entire valve. The insertion of the support base 20 into the valve stem 5 assists in the installation of the support plate 13 on top of the valve stem 5. The insertion of the extension strip 12 into the limiting rod 19 guides the installation of the support base 20 on top of the valve stem 5. The limiting block 16 limits the installation of the electrical control box 9 on top of the support plate 13, reducing the shaking of the electrical control box 9. When the electrical control box 9 is in normal use, the cooling fan 15 and the cooling pipe 18 located in the middle can be connected. The connection between 18 allows air to be supplied to the other two heat dissipation pipes 18 through branch pipe 21. When the air flows inside the heat dissipation pipe 18, it can cool the support plate 13. The air is discharged through the end of the heat dissipation pipe 18, which can accelerate the air flow around the power failure protector 14 and the heat dissipation fins 17, thereby achieving heat dissipation assistance for the electrical control box 9 and reducing the heat accumulation inside the electrical control box 9. When the electrical control box 9 malfunctions, the power failure protector 14 and the alarm 8 will work, and the alarm 8 will sound an alarm, which will help the staff to discover the valve abnormality in time and carry out maintenance.

[0026] As an optimization solution, such as Figure 1 and Figure 2 As shown, a sealing ring is fixedly connected to the inner ring surface of the valve body 10, and a guide member 11 is fixedly connected to the outer ring surface of the valve body 10. A plug rod 7 is inserted into the guide member 11, and a reinforcing ring 3 is fixedly connected to one end of the plug rod 7. The reinforcing ring 3 is slidably connected to the valve body 10. An extension tube 2 is fixedly connected to the inner ring surface of the reinforcing ring 3, and a sealing ring 1 is fixedly connected to the inner ring surface of the extension tube 2. One end of the extension tube 2 overlaps with the sealing ring. A limiting member 4 is inserted into the outer ring surface of the valve body 10. The inner wall of the limiting member 4 is engaged with the plug rod 7, and the limiting members 4 are connected by a connecting bolt 6 through a thread.

[0027] Specifically, the sealing ring can be used to seal and protect the connection between the extension tube 2 and the valve body 10. The guide 11 can guide the installation of the reinforcing ring 3 on both sides of the valve body 10. The engagement of the limiting member 4 with the valve body 10 can limit the connection between the plug rod 7 and the guide 11, ensuring a stable connection between the plug rod 7 and the guide 11. The connecting bolt 6 can fix the limiting members 4 on both sides, thereby reducing the loosening of the limiting members 4 after installation, ensuring the stability of the limiting members 4 during use, and facilitating the subsequent disassembly of the limiting members 4.

[0028] Working principle: First, the reinforcing ring 3 slides along the valve body 10. At this time, the end of the extension tube 2 is inserted into the valve body 10 and overlaps with the sealing ring on the inner wall of the valve body 10. Then, the insertion rod 7 is inserted into the guide 11, and the limiting member 4 is inserted into the valve body 10. The limiting member 4 and the insertion rod 7 are engaged. Rotate the connecting bolt 6 so that the end of the connecting bolt 6 passes through the limiting member 4 on one side and connects with the limiting member 4 on the other side, thereby limiting and fixing the limiting member 4. During the use of the entire valve, the circuit inside the electric control box 9 can be driven by the external controller to control the opening and closing of the valve. When an abnormality occurs inside the control box 9, the power failure protector 14 will activate and the alarm 8 will sound, reminding the staff to inspect the control box 9 in time. At this time, the support base 20 will be moved upward, so that the support base 20 and the limit rod 19 will be separated from the valve stem 5 and the extension bar 12 respectively. Then, the extension bar 12 will be rotated, and the valve stem 5 will drive the valve core inside the valve body 10 to rotate, which can close the valve. The cooling fan 15 will exhaust air through the heat dissipation pipe 18 and the branch pipe 21, accelerating the air flow around the top of the support plate 13 and the heat dissipation fins 17, thereby accelerating the heat dissipation of the control box 9 and ensuring the operating temperature of the control box 9.
