[0025] In the specific implementation process, it is worth noting that, under the cooperation of the servo motor 21, the connecting rod 22 and the gear 23, the servo motor 21 is used to drive the connecting rod 22 to rotate, and the gear 23 is engaged with the ring gear 24 to drive the driving rod 25 to rotate, so that the driving rod 25 drives the ball 12 to rotate, closing or opening the valve body 1, solving the problem of the prior art that when in use, the staff needs to be close to the valve body 1 for adjustment, which causes inconvenience to the staff during use;

[0026] Furthermore, a simple structure 3 is installed on the top of the driving rod 25. The simple structure 3 includes: a connecting block 31, fixedly connected to one end of the driving rod 25 extending to the top of the fixed shell 15; a handle 32, inserted into the top of the connecting block 31, and a diamond groove is provided at the connecting portion of the connecting block 31 and the handle 32. When the handle 32 is inserted into the connecting block 31, it can drive the driving rod 25 to rotate; wherein, the driving rod 25 rotates through the cooperation between the connecting block 31 and the handle 32.

[0027] In the specific implementation process, it is worth noting that, with the cooperation of the handle 32, the connecting block 31 and the driving rod 25, when the servo motor 21 fails, the handle 32 is inserted into the top of the connecting block 31, and the handle 32 is used to drive the driving rod 25 to rotate, thereby opening and closing the valve body 1;

[0028] Furthermore, a sealing structure 4 is installed on the outer wall of the driving rod 25. The sealing structure 4 includes: a sealing gasket 41, which is sleeved on the outer wall of the driving rod 25 and pressed against the top of the valve body 1; a sealing plate 42, which is sleeved on the top of the driving rod 25 and pressed against the top of the sealing gasket 41, and is fixedly connected to the top of the valve body 1 by bolts; wherein, the valve body 1 is sealed by the cooperation of the sealing gasket 41 and the sealing plate 42;

When assembling the valve body, a sealing gasket 41 is placed in the gap between the driving rod 25 and the valve body 1, and it is tightened with a sealing plate 42 to seal the valve body 1.

[0031] Example 2: By Figure 1-5 It can be seen that the inner wall of the fixed shell 15 is fixedly connected to the pressure switch 5, the pressure switch 5 is electrically connected to the alarm 6, and the outer wall of the alarm 6 is fixedly connected to the outer wall of the fixed shell 15. The pressure switch 5 and the alarm 6 are used in conjunction with each other, and their specific models are not limited, as long as they meet the actual usage conditions;

[0032] During the specific implementation process, it is worth noting that, with the cooperation of the pressure switch 5, the fixed shell 15 and the alarm 6, when the valve body 1 leaks, the pressure in the fixed shell 15 will increase, thereby triggering the pressure switch 5, causing the pressure switch 5 to activate the alarm 6, causing the alarm 6 to sound, notifying the staff of the leakage and promptly repairing the valve body 1;

[0033] Furthermore, a protective net 14 is provided on the inner wall of the valve body 1, and a mounting frame 16 is fixedly connected to the outer wall of the protective net 14.

[0035] Specifically, based on the above embodiment, when the valve body 1 is used, the protective net 14 is installed at the water inlet of the valve body 1 to prevent impurities from affecting the sphere 12 in the valve body 1. When blockage occurs, the pressure at the water inlet of the valve body 1 will increase, causing the pointer of the pressure gauge 13 to move. When the valve body 1 leaks, the pressure in the fixed shell 15 will increase, thereby triggering the pressure switch 5 and causing the alarm 6 to sound an alarm, alerting the staff to the leakage.
