[0020] 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.

[0021] Please see Figures 1-5 This embodiment provides an anti-interference ball valve, including a base 1 and a ball valve body 2. The upper surface of the base 1 has symmetrically arranged bottom grooves. A stud 11 is rotatably installed in the bottom groove via a thread. A sleeve 12 is screwed to the outer wall of the stud 11. A connecting sleeve 13 is installed on the upper surface of the sleeve 12. The ball valve body 2 is installed on the inner end of the connecting sleeve 13. A handle 14 is rotatably installed on the upper surface of the ball valve body 2 via a bearing. A pressure sensor 15 is embedded in the bottom of the bottom groove. The bottom of the stud 11 is tightly attached to the upper surface of the pressure sensor 15. Buzzers 16 are symmetrically embedded on the left and right side walls of the base 1. A control panel 17, pressure sensor 15, and buzzers 16 are arranged inside the base 1. All 6 are electrically connected to the control panel 17. The control panel 17 contains a PLC program to control the operation of each device. During operation, the base 1 is cast on the corresponding ground, and the stud 11 is rotated to abut against the bottom of the groove, thereby connecting and fixing the ball valve body 2 to prevent the ball valve body 2 from shaking and causing the connection to loosen, thus improving the stability of the device connection. When the ball valve body 2 vibrates too much, the stud 11 rotates and moves upward. The pressure sensor 15 senses the disappearance of pressure and transmits the signal to the control panel 17, thereby controlling the buzzer 16 to sound an alarm, so that the staff can promptly rotate and tighten the stud 11.

[0022] A fixed cavity 18 is installed on the upper end face of the base 1. An adjusting screw 19 is rotatably installed on the left end face of the fixed cavity 18 via a bearing. The adjusting screw 19 has symmetrical left and right threads with opposite directions. A first slider is symmetrically screwed to the outer wall of the adjusting screw 19. A connecting frame 21 is installed on the upper end face of the first slider. A plug rod 22 is installed on the outer end of the connecting frame 21. A plug hole is opened on the outer wall of the stud 11. The plug rod 22 is inserted into the plug hole. During operation, rotating the adjusting screw 19 moves the plug rod 22 outward into the plug hole, thereby limiting the stud 11 and preventing the stud 11 from rotating accidentally.

[0023] The bottom of the connecting frame 21 is connected to the upper surface of the base 1 by a sliding fit. During operation, the sliding fit is used to ensure the stability of the insertion rod 22 when moving left and right.

[0024] An outer slot is provided at the outer end of the insertion rod 22. A first screw 23 is installed in the outer slot by screwing. A bracket 24 is installed at the outer end of the first screw 23. During operation, the bracket 24 limits the insertion rod 22 to prevent it from moving inward and disengaging from the insertion hole, thereby further improving the stability of the device.

[0025] The bottom of the outer side wall of the handle 14 is symmetrically provided with lower slots. A triangular cone 25 is installed in the lower slot by insertion. A spring rod 26 is installed at the bottom of the triangular cone 25. The spring rod 26 is arranged at an angle. When working, the spring rod 26 drives the triangular cone 25 to move upward and insert into the bottom of the handle 14, thereby preventing the handle 14 from rotating accidentally and ensuring the sealing performance of the ball valve body 2.

[0026] A side mesh 27 is arranged on the outer end of the buzzer 16. Multiple through holes are opened on the outer end of the side mesh 27. When working, the side mesh 27 protects the buzzer 16, while the sound of the buzzer 16 is emitted through the through holes, so as not to affect its normal function.

[0027] In actual operation, the base 1 is cast on the corresponding ground, and the stud 11 is rotated to abut against the bottom of the groove, thereby connecting and fixing the ball valve body 2. This prevents the ball valve body 2 from shaking and causing the connection to loosen, thus improving the stability of the device connection. When the ball valve body 2 vibrates too much, the stud 11 rotates and moves upward. The pressure sensor 15 senses the disappearance of pressure and transmits the signal to the control panel 17, thereby controlling the buzzer 16 to sound an alarm, so that the staff can promptly rotate and tighten the stud 11.

[0028] 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.
