Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0027] In this technical solution, a valve with an anti-corrosion function includes a first pipe body 1 and a second pipe body 2.

The anti-corrosion switch structure includes a first control pipe body 3, a second control pipe body 4, a first operation pipe 5, a second operation pipe 6, three operation grooves 7, three sealing plates 8, a first driving component, a second driving component, and a liquid discharge component;

[0028] One end of the first control pipe body 3 is connected to one end of the first pipe body 1 through a flange. One end of the second control pipe body 4 is connected to one end of the first control pipe body 3 through a flange. One end of the second pipe body 2 is connected to one end of the second control pipe body 4 through a flange. The first operation pipe 5 is embedded in the first control pipe body 3. The second operation pipe 6 is embedded in the second control pipe body 4. One of the operation grooves 7 is opened in the first operation pipe 5. The other two operation grooves 7 are opened on both sides of the second operation pipe 6. The three sealing plates 8 are respectively movably embedded in the three operation grooves 7. The first driving component is installed at the upper end of the first control pipe body 3. The second driving component is installed at the upper end of the second control pipe body 4. One end of the liquid discharge component is communicated with one side of the second operation pipe 6.

[0029] In this technical solution, during installation, the first control pipe body 3 and the second control pipe body 4 are connected through a flange. Subsequently, both ends of the first control pipe body 3 and the second control pipe body 4 are respectively connected to the first pipe body 1 and the second pipe body 2. A passage is formed through the first pipe body 1, the first control pipe body 3, the second control pipe body 4, and the second pipe body 2. During daily use, by the operation of the second driving component, two of the sealing plates 8 are driven to move in the two operation grooves 7 to close the second operation pipe 6, and the closing operation of the passage can be realized. When the valve is regularly overhauled, by the operation of the first driving component, the sealing plate 8 in the first operation pipe 5 is closed to seal the conveying pipeline, and then the first control pipe body 3 and the second control pipe body 4 can be disconnected through the flange to overhaul the components in the second control pipe body 4. When facing a long-term closure of the passage, by the synchronous operation of the first driving component and the second driving component, the three sealing plates 8 are pushed downward to completely seal the first operation pipe 5 and the second operation pipe 6. Subsequently, the liquid between the second control pipe body 4 and the first control pipe body 3 is discharged through the liquid discharge component, avoiding the long-term contact of the components with the liquid and reducing the probability of component corrosion.

The bottom end of the connecting frame 12 is connected to one of the sealing plates 8, and the top end is movably sleeved on the upper end of the first lead screw 11.

[0032] In this technical solution, when closing the first operation pipe 5, the first motor 10 at the upper end of the first operation box body 9 works. The first motor 10 drives the first lead screw 11 to rotate. Through the cooperation between the first lead screw 11 and the internal thread in the connecting frame 12, the connecting frame 12 is adjusted in the first operation box body 9.

The two lower sides of the moving plate 16 are respectively connected to the upper ends of the two sealing plates 8, and the moving plate 16 is movably sleeved on the upper end of the second lead screw 15.

[0035] In this technical solution, when closing the second operation pipe 6, the second motor 14 at the upper end of the second operation box body 13 works. The second motor 14 drives the second lead screw 15 to rotate. Through the cooperation between the second lead screw 15 and the internal thread in the moving plate 16, the moving plate 16 is adjusted in the second operation box body 13. Through the cooperation between the moving plate 16 and the other two sealing plates 8, the second operation pipe 6 is switched on and off.

[0038] In this technical solution, when both the first operation pipe 5 and the second operation pipe 6 are closed, the control valve 18 at the upper end of the liquid discharge pipe 17 is opened, and the liquid between the second control pipe body 4 and the first control pipe body 3 is discharged through the liquid discharge pipe 17, avoiding the long-term contact between the components and the liquid and reducing the probability of component corrosion.

[0039] In some technical solutions, referring to Figure 1, a first guiding rod 19 is provided inside the first operation box body 9, the first guiding rod 19 is movably embedded on both sides of the connecting frame 12, a second guiding rod 20 is provided inside the second operation box body 13, and the second guiding rod 20 is movably embedded on both sides of the moving plate 16.

[0040] Working principle:

[0041] During installation, the first control pipe body 3 and the second control pipe body 4 are connected through a flange. Subsequently, both ends of the first control pipe body 3 and the second control pipe body 4 are respectively connected to the first pipe body 1 and the second pipe body 2 to form a passage through the first pipe body 1, the first control pipe body 3, the second control pipe body 4, and the second pipe body 2. During daily use, when closing the second operation pipe 6, the second motor 14 at the upper end of the second operation box body 13 works, the second motor 14 drives the second lead screw 15 to rotate, and through the cooperation of the second lead screw 15 and the internal thread in the moving plate 16, the moving plate 16 is adjusted inside the second operation box body 13. Through the cooperation of the moving plate 16 and the other two sealing plates 8, the second operation pipe 6 is sealed, and the closing operation of the passage can be realized. When regularly overhauling the valve, when closing the first operation pipe 5, the first motor 10 at the upper end of the first operation box body 9 works, the first motor 10 drives the first lead screw 11 to rotate, and through the cooperation of the first lead screw 11 and the internal thread in the connecting frame 12, the connecting frame 12 is adjusted inside the first operation box body 9. Through the cooperation of the connecting frame 12 and one of the sealing plates 8, the sealing plate 8 inside the first operation pipe 5 is closed, and the conveying pipeline is closed. Then, the flange can be used to disconnect the first control pipe body 3 and the second control pipe body 4, and the parts inside the second control pipe body 4 can be overhauled. When facing a long-term closing of the passage, the first driving component and the second driving component work synchronously to push the three sealing plates 8 downward to completely seal the first operation pipe 5 and the second operation pipe 6. Then, the control valve 18 at the upper end of the drain pipe 17 is opened, and the liquid between the second control pipe body 4 and the first control pipe body 3 is discharged through the drain pipe 17 to avoid the long-term contact of the parts with the liquid and reduce the probability of the parts being corroded.
