Detailed Embodiment

[0027] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0028] Referring to the attached Figures 1-6 , a bidirectional metal-sealed butterfly valve with high protection provided by the present invention includes a butterfly valve body 1. Connecting pipes 2 are fixedly connected to both sides of the butterfly valve body 1. A sealing plate 3 is embedded in the butterfly valve body 1. A transmission shaft 4 is provided on the top of the sealing plate 3. The top end of the transmission shaft 4 extends to the outside of the top of the butterfly valve body 1. A turntable 5 is fixedly connected to the top of the transmission shaft 4;

[0029] At the bottom of the butterfly valve body 1, there is a rotating rod 6. Two gears 7 are fixedly sleeved on the outer side of the rotating rod 6. Two moving grooves 8 are formed inside the butterfly valve body 1. Two toothed rings 9 are embedded in each of the two moving grooves 8. Two connecting rings 10 are embedded in each of the two moving grooves 8. The two connecting rings 10 are fixedly connected to the two toothed rings 9 respectively. A plurality of sliders 11 are fixedly connected to the inner sides of the two connecting rings 10. Two threaded pipes 12 are embedded in the butterfly valve body 1. A plurality of sliding grooves 13 are formed on the outer sides of the two threaded pipes 12. The plurality of sliders 11 are respectively embedded in the plurality of sliding grooves 13.

[0030] A base 14 is provided at the bottom of the butterfly valve body 1. A moving groove 15 is formed inside the base 14. A first threaded rod 16 and a second threaded rod 17 are embedded in the moving groove 15. The outer sides of the first threaded rod 16 and the second threaded rod 17 are sleeved with a first sleeve 18 and a second sleeve 19 respectively. A rotating shaft 20 is embedded in the moving groove 15. The rotating shaft 20 is fixedly embedded on the outer sides of the first threaded rod 16 and the second threaded rod 17.

[0031] In this embodiment, in the present invention, the user places two transfer pipes inside the two connecting pipes 2, so that the two transfer pipes are engaged with the two threaded rods. After the engagement is completed, the first knob 25 is rotated. The rotation of the first knob 25 drives the rotation of the rotating rod 6. The rotation of the rotating rod 6 drives the rotation of the two gears 7. The rotation of the two gears 7 drives the rotation of the two toothed rings 9. The rotation of the two toothed rings 9 drives the rotation of the two connecting rings 10. The rotation of the two connecting rings 10 drives the rotation of the plurality of sliders 11. Since the slider 11 is slidably connected to the sliding groove 13, and because the threaded pipe 12 is engaged with the transfer pipe, the rotation of the slider 11 drives the rotation of the threaded pipe 12, so that the two threaded pipes 12 are sleeved on the outer sides of the two transfer pipes to achieve installation. At the same time, the first knob 25 is rotated in the reverse direction to achieve disassembly.

[0032] Among them, in order to achieve the purpose of support and protection, the present device is realized by the following technical solution: One end of the rotating rod 6 is fixedly connected to a first knob 25. Two fixing plates 21 are fixedly connected to the bottom of the butterfly valve body 1. Two round rods 22 are fixedly connected to the bottoms of the two fixing plates 21. Support plates 23 are sleeved on the outer sides of the two round rods 22. Two through grooves 24 are formed on the top of the base 14. The bottoms of the two support plates 23 respectively penetrate through the two through grooves 24 and extend into the moving groove 15. The bottoms of the two support plates 23 are respectively movably connected to the first sleeve 18 and the second sleeve 19 through hinges. The front end of the rotating shaft 20 extends to the outside of the front side of the base 14. The front end of the rotating shaft 20 is fixedly connected to a second knob 26. Two protective covers 27 are fixedly connected to the bottom of the butterfly valve body 1. The two protective covers 27 are respectively sleeved on the outer sides of the two gears 7.

[0033] When the device needs to support and protect the butterfly valve body 1, turn the second knob 26. The rotation of the second knob 26 drives the rotation of the first threaded rod 16 and the second threaded rod 17. The rotation of the first threaded rod 16 and the second threaded rod 17 drives the movement of the first sleeve 18 and the second sleeve 19. The movement of the first sleeve 18 and the second sleeve 19 drives the upward movement of the two support plates 23. The movement of the two support plates 23 supports and fixes the butterfly valve body 1, thereby playing a role in protecting the butterfly valve body 1.

[0034] Among them, in order to achieve the purpose of limiting, the device is realized by the following technical scheme: both sides of the two connecting rings 10 are fixedly connected with limiting rings 28. Two limiting grooves are respectively embedded in the two movable grooves 8. The multiple limiting rings 28 are respectively embedded in the multiple limiting grooves. The outer sides of the first sleeve 18 and the second sleeve 19 are both square structures. The two first sleeves 18 and the second sleeve 19 are respectively in contact with the moving groove 15.

[0035] Among them, in order to achieve the purpose of connection, the device is realized by the following technical scheme: the transmission shaft 4 is movably connected with the butterfly valve body 1 through a rolling bearing. The connection parts of the rotating rod 6 and the two protective covers 27 are both movably connected through a rolling bearing. The connection part of the rotating shaft 20 and the base 14 is movably connected through a rolling bearing. The two gears 7 are respectively meshed with the two toothed rings 9. The first threaded rod 16 is threadedly connected with the first sleeve 18. The second threaded rod 17 is threadedly connected with the second sleeve 19. The rolling bearing movable connection makes the rotation of each connection part more smooth.

[0036] The use process of the present invention is as follows: The user places the two transmission pipes in the two connecting pipes 2 of the present invention, so that the two transmission pipes are meshed with the two threaded rods. After the meshing is completed, turn the first knob 25. The rotation of the first knob 25 drives the rotation of the rotating rod 6. The rotation of the rotating rod 6 drives the rotation of the two gears 7. The rotation of the two gears 7 drives the rotation of the two toothed rings 9. The rotation of the two toothed rings 9 drives the rotation of the two connecting rings 10. The rotation of the two connecting rings 10 drives the rotation of the multiple sliders 11. Since the sliders 11 are slidably connected with the sliding grooves 13 and the threaded pipes 12 are meshed with the transmission pipes, the rotation of the sliders 11 drives the rotation of the threaded pipes 12, so that the two threaded pipes 12 are sleeved outside the two transmission pipes to realize installation. At the same time, turn the first knob 25 in the reverse direction to realize disassembly. When the device needs to support and protect the butterfly valve body 1, turn the second knob 26. The rotation of the second knob 26 drives the rotation of the first threaded rod 16 and the second threaded rod 17. The rotation of the first threaded rod 16 and the second threaded rod 17 drives the movement of the first sleeve 18 and the second sleeve 19. The movement of the first sleeve 18 and the second sleeve 19 drives the upward movement of the two support plates 23. The movement of the two support plates 23 supports and fixes the butterfly valve body 1, thereby playing a role in protecting the butterfly valve body 1. The rolling bearing movable connection makes the rotation of each connection part more smooth.

Any person skilled in the art may modify the present invention by using the technical solutions described above or modify them into equivalent technical solutions. Therefore, any simple modification or equivalent substitution made according to the technical solutions of the present invention falls within the scope of the present invention claimed.
