[0033] Two sealing rings 21 are located on the opposite side of the outer surface of the spherical valve core 22 to improve the sealing performance of the spherical valve core 22 and the valve body 5. The driven gear 20 and the driving gear 25 are meshed and connected. The connecting rod 23 passes through the valve body 5 through the through-hole 16. The first sealing component 19 has a bearing and a sealing structure inside, which is sleeved on the outer surface of the connecting rod 23. In conjunction with the sealing ring 17, the angle of the connecting rod 23 can be adjusted without leakage. The mounting shell 4 is covered on the outer surface of the docking frame 18.

A through-hole is opened on the opposite side of the outer surface of the spherical valve core 22, which corresponds to the shape of the inlet and outlet of the valve body 5.

[0034] Both ends of the valve body 5 are fixedly connected to a connecting pipe 7, and the other end of the connecting pipe 7 is fixedly connected to a flange 6;

[0035] The flange 6 facilitates the connection between the valve body 5 and the corresponding pipeline, and the connecting pipe 7 and the valve body 5 are connected.

[0036] The outer surface of one of the connecting pipes 7 is fixedly connected to a mounting base 13 , and a fixing bolt 14 is installed on the top of the mounting base 13 ;

[0037] Mounting base 13 position reference Figure 2 , the middle of the fixing bolt 14 is empty.

[0044] The working principle of the intelligent valve opening and closing mechanism provided by the utility model is as follows:

[0045] A through-hole 16 is opened at the top of the valve body 5 for the connecting rod 23 to pass through, and then the spherical valve core 22 is installed inside the valve body 5 through the connecting rod 23, so that the spherical valve core 22 is located between the two sealing rings 21, and the connection between the connecting rod 23 and the through-hole 16 is sealed by the sealing ring 17 and the first sealing component 19, so that the connecting rod 23 can rotate while ensuring the sealing. A driven gear 20 is installed on the top of the connecting rod 23 and is connected to the driving gear 25 at the output end of the driving component 3. The driven gear 20 is driven to rotate by adjusting the angle of the driving component 3 to move the ball. The spherical valve core 22 is adjusted in angle to realize the opening and closing of the valve body 5. In actual use, if the valve body 5 needs to be closed, remote control is realized by receiving the signal through the signal line 10. It is only necessary to start the driving component 3 to drive the driven gear 20 to rotate through the driving gear 25, so as to drive the spherical valve core 22 to rotate, so that the through-hole of the spherical valve core 22 and the inlet and outlet of the valve body 5 are misaligned, thereby realizing the closing of the valve body 5. If the valve body 5 needs to be opened, it is also only necessary to drive the spherical valve core 22 to rotate through the driving component 3 to align the through-hole of the spherical valve core 22 with the inlet and outlet of the valve body 5.

[0046] Compared with related technologies, the intelligent valve opening and closing mechanism provided by the present invention has the following beneficial effects:

[0047] In order to simplify the structure of the intelligent valve and facilitate later maintenance, a through-hole 16 is opened at the top of the valve body 5 for the connecting rod 23 to pass through, and then the spherical valve core 22 is installed inside the valve body 5 through the connecting rod 23, so that the spherical valve core 22 is located between the two sealing rings 21, and the connection between the connecting rod 23 and the through-hole 16 is sealed by the sealing ring 17 and the first sealing component 19, so that the connecting rod 23 can rotate while ensuring the sealing. A driven gear 20 is installed at the top of the connecting rod 23 and is connected to the driving gear 25 at the output end of the driving component 3. The angle adjustment of the driving component 3 drives the driven gear 20 to rotate, which can move the spherical valve core 22 for angle adjustment, thereby realizing the opening and closing of the valve body 5. This design simplifies the structure of the opening and closing mechanism of the intelligent valve, and replaces manual opening and closing with the remotely controlled driving component 3, which improves the intelligence while facilitating later maintenance and reducing the maintenance cost when a failure occurs in the later stage.
