DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 3 and Figure 4 The utility model provides a technical solution: a rust-proof and high-temperature resistant fast opening and closing fluorine-lined kettle bottom valve, comprising a valve body assembly 1, a shut-off valve mechanism 3 arranged at the oblique top of the valve body assembly 1, the valve body assembly 1 comprising an oblique neck valve tube 11, the valve body assembly 1 also comprising an access tube 12, the access tube 12 is fixedly connected to the middle part of the outer side of the oblique neck valve tube 11, a disassembly assembly 2 is arranged in the access tube 12, the disassembly assembly 2 comprises a screw column 21 that can be quickly disassembled and assembled in the access tube 12, and the screw column 21 is also provided with an anti-blocking assembly 4 that can stir the oblique neck valve tube 11 and thus avoid material blockage. Compared with the comparative documents, the present design solves the problem in the prior art that a large amount of medium residue will adhere to the surface of the impeller blades and the electric control vibration plate during long-term use, and it is impossible to quickly remove the anti-blocking components such as the impeller blades and the electric control vibration plate from the valve tube and complete the cleaning of the medium attached to the surface.

[0024] See also Figure 3The disassembly and assembly component 2 also includes a threaded ring 211, which is distributed on the outside of the screw column 21. The threaded ring 211 matches the threaded groove on the inner wall of the access pipe 12. The screw column 21 is threadedly connected to the access pipe 12 through the threaded ring 211. Through this design, the threaded installation work of the screw column 21 in the access pipe 12 can be completed.

[0025] See also Figure 3 The disassembly and assembly component 2 also includes a sealing ring 212, which is fixedly connected to the outside of the screw column 21. The sealing ring 212 can increase the sealing performance of the connection between the access pipe 12 and the screw column 21.

[0026] See also Figure 3 The disassembly assembly 2 further includes a back cover 22 , which is snapped onto the back of the screw post 21 . By disassembling the back cover 22 , the motor 41 in the screw post 21 can be disassembled and repaired.

[0027] See also Figure 4 The disassembly and assembly component 2 also includes a mounting bracket 23, which is fixedly connected to the inside of the screw column 21. The mounting bracket 23 can support and fix the motor 41 in the screw column 21.

[0028] See also Figure 4 The anti-blocking component 4 includes a motor 41, which is arranged in the screw column 21 and fixedly mounted on the top of the mounting bracket 23. The anti-blocking component 4 also includes a rotating shaft 411, one end of which is fixedly connected to the output end of the motor 41. The anti-blocking component 4 also includes a rotating rod 42, which is fixedly connected to the rotating shaft 411. The anti-blocking component 4 also includes an impeller plate 421, which is fixedly connected to the outside of the rotating rod 42 in an annular shape. When the screw column 21 is installed in the access pipe 12, the motor 41 can be started to drive the output end of the motor 41 to rotate the rotating shaft 411. At this time, the rotating rod 42 and the impeller plate 421 fixedly connected to the side of the rotating shaft 411 will rotate synchronously, thereby achieving the purpose of preventing the medium from being blocked in the oblique neck valve tube 11.

[0029] See also Figure 4 The disassembly and assembly component 2 also includes a waterproof bearing 24, which is arranged at the side wall of the screw column 21. The outer ring of the waterproof bearing 24 is fixedly connected to the screw column 21, and the inner ring of the waterproof bearing 24 is fixedly connected to the rotating shaft 411. The waterproof bearing 24 can prevent the medium from flowing into the screw column 21, and the rotating shaft 411 on the side of the screw column 21 can rotate more smoothly.

[0030] The working principle and use process of this utility model are as follows:

[0031] The outer side of the screw post 21 is aligned with the access tube 12, and the screw post 21 can be screwed into the access tube 12 and fixed in place by the threaded ring 211 matching the thread groove in the access tube 12. When the screw post 21 is screwed into the access tube 12, the sealing ring 212 on the outer side of the screw post 21 fits against the edge of the access tube 12 to maintain the sealing connection between the two. Similarly, when it is necessary to clean the rotating rod 42 and the impeller plate 421, the screw post 21 can be reversed to complete the disassembly of the screw post 21 and the anti-blocking component 4 at the valve body assembly 1. This design makes it easy to remove the rotating rod 42 and the impeller plate 421 at a later time and to clean the residual medium attached to the surface.

[0032] When the screw column 21 is screwed into and fixed in the access pipe 12, the rotating shaft 411 can be driven to rotate by starting the output end of the motor 41. At this time, the rotating rod 42 fixedly connected to the side of the rotating shaft 411 and the impeller plate 421 will rotate synchronously. This design can prevent the medium from being blocked in the oblique neck valve tube 11.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
