The clamping column rod 39 is located inside the spacing between the clamping plates 8, so that the clamping column rod 39 can slide inside the annular groove 7 and between the clamping plates 8, thereby achieving the effect of locking the solid rotating column 6.

[0029] As a further implementation of the present invention, the front end of the polyhedral groove 32 is in the shape of a rectangular body, the rear end of the polyhedral groove 32 is in the shape of a cylinder, the anti-counterfeiting slide 33 is fixed on the left and right sides of the polyhedral groove 32 opened in the housing 31, and the anti-counterfeiting slide 33 slides inside the anti-counterfeiting slide 42, further preventing the non-management staff from operating the device, and further improving the safety performance of the ball valve;

[0032] Working process: the solid rotating column 6 is locked to prevent non-staff from operating it incorrectly. During the normal operation of the ball valve body 1, the built-in magnetic plate 37 is kept moving in the direction of the solid rotating column 6 under the elastic pulling force of the spring 38. One end of the built-in magnetic plate 37 is fixedly connected to the limiting slider. The built-in magnetic plate 37 is slidably connected to the column channel 35 and the limiting slideway 36 opened inside the built-in orifice plate 34, so as to limit the movement of the built-in magnetic plate 37. The built-in magnetic plate 37 drives the clamping column rod 39 fixedly connected on one side to move. The clamping column rod 39 moves in the direction of the solid rotating column 6. The clamping column rod 39 slides inside the annular groove 7 opened in the solid rotating column 6. At the same time, the clamping column rod 39 slides in the space between the clamping plates 8. At this time, the rear end of the clamping column rod 39 is in contact with the outer side of the solid rotating column 6. Under the action of the clamping plate 8 and the clamping column rod 39, the solid rotating column 6 can be locked to prevent the operating handle 5 from driving the solid rotating column 6 to rotate, thereby preventing the ball valve from being operated. When impacted by water, it rotates, thereby improving the stability of the ball valve switch and preventing non-staff from operating it incorrectly. When the solid rotating column 6 needs to be rotated, the staff is equipped with the lock assembly 4, and slides the unlocking plate 41 inside the multi-shaped groove 32 opened in the shell 31. At the same time, the anti-counterfeiting slide 42 opened on the unlocking plate 41 slides on the outside of the anti-counterfeiting slide bar 33. The anti-counterfeiting slide 42 and the anti-counterfeiting slide bar 33 play a role in controlling the model of the unlocking plate 41, further preventing non-staff from operating the device, and further improving the safety performance of the ball valve. When the rear end of the unlocking plate 41 is in contact with the front end of the built-in orifice plate 34, the magnetic column 43 and the built-in magnetic plate 37 are magnetically attracted to each other, and the built-in magnetic plate 37 moves toward the direction of the magnetic column 43. The built-in magnetic plate 37 drives the clamping column rod 39 to move, and the clamping column rod 39 is away from the inside of the annular groove 7 and between the clamping plate 8, so that the solid rotating column 6 can be controlled to rotate when the turning handle 5 is turned, thereby realizing the function of controlling the switch of the ball valve.
