[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Please see Figures 1-5This embodiment provides an encrypted anti-interference gate valve, including a gate valve body 1 and a handle 2. A connecting sleeve 11 is installed on the upper end of the outer wall of the gate valve body 1. The handle 2 is rotatably installed on the upper surface of the connecting sleeve 11 via a pin. A buckle 12 is symmetrically fitted on the outer wall of the handle 2, with a notch at the bottom. A connecting rod 13 is symmetrically installed on the outer wall of the connecting sleeve 11 via a pin, and a hook 14 is rotatably installed on the other end of the connecting rod 13 via a pin. A connecting plate 15 is symmetrically installed on the bottom of the buckle 12, with a through hole at the outer end of the connecting plate 15. The hook 14 passes through the through hole. Both the hook 14 and the connecting plate 15 are made of magnetic material. During operation, the opening and closing of the gate valve body 1 is controlled by rotating the handle 2. When the gate valve body 1 is in the closed state, the buckle 12 plays a role in limiting and fixing the handle 2, preventing the handle 2 from rotating and causing the gate valve body 1 to open accidentally, thereby ensuring the stability of the device. The use of magnetic material ensures the connection between the hook 14 and the connecting plate 15 and ensures the limiting effect of the buckle 12 on the handle 2. Rotating the hook 14 removes it, allowing the buckle 12 to be removed through the notch.

[0020] The inner end of the buckle 12 is equipped with a plug 16, and the inner end of the handle 2 is provided with a positioning groove that matches it. The bottom of the handle 2 is equipped with a lower plate 17, which is arranged at the notch of the buckle 12. During operation, the plug 16 is used to position and fix the buckle, further ensuring the stability of the device. The lower plate 17 prevents the buckle 12 and the handle 2 from rotating relative to each other.

[0021] A pressure sensor 18 is embedded in the inner end of the plug 16, and a buzzer 19 is installed on the upper end of the outer wall of the buckle 12. A control board 21 is arranged in the inner end of the buckle 12. The pressure sensor 18 and the buzzer 19 are electrically connected to the control board 21. The control board 21 is programmed with a PLC to control the operation of each device. During operation, the plug 16 is engaged in the positioning slot. The pressure sensor 18 senses the pressure. When the buckle 12 disengages, the pressure disappears and a signal is transmitted to the control board 21, causing the buzzer 19 to sound an alarm, thereby reminding the staff to perform timely reset and maintenance to ensure the stability of the device installation.

[0022] A connector 22 is installed on the upper end face of the handle 2. Connecting ropes 23 are symmetrically installed on the outer side wall of the connector 22. The other end of the connecting rope 23 is installed on the outer side wall of the buckle 12. During operation, the connecting rope 23 structure is used to connect the buckle 12 and prevent the buckle 12 from being lost.

[0023] The gate valve body 1 is symmetrically equipped with flanges 24 on its left and right sides. Fixing sleeves 25 are symmetrically installed on the outer walls of the gate valve body 1 on its left and right sides. Multiple adjusting grooves are installed along the circumferential direction on the outer walls of the fixing sleeves 25. Adjusting screws 26 are rotatably installed in the adjusting grooves via bearings. Adjusting sliders are screwed to the outer walls of the adjusting screws 26. Limit frames 27 are installed on the upper surface of the adjusting sliders. During operation, the gate valve body 1 is connected to the inlet and outlet pipes via flanges. After the connection is completed, rotating the adjusting screws 26 causes the limit frames 27 to move inward, thereby clamping and fixing the flange connection. This ensures the stability of the connection between the gate valve body 1 and the inlet and outlet pipes.

[0024] In actual operation, the gate valve body 1 is opened and closed by rotating the handle 2. When the gate valve body 1 is in the closed state, the buckle 12 limits and fixes the handle 2, preventing the handle 2 from rotating and causing the gate valve body 1 to open accidentally, thus ensuring the stability of the device. Magnetic material is used to ensure the connection between the hook 14 and the connecting plate 15 and to ensure the limiting effect of the buckle 12 on the handle 2. Rotating the hook 14 removes it, allowing the buckle 12 to be removed through the notch.

[0025] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
