[0024] The following will be combined with the drawings in 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.

[0025] See also Figure 1-5 The utility model provides a technical solution: a boiler seal adapted to the connection of multi-diameter pipes, according to Figure 1-3 As shown, pipe connectors 2 are symmetrically provided on both sides of the boiler seal body 1 .

[0026] Specifically, a high-temperature resistant elastic sleeve 201 is installed inside the pipe connector 2, and a first fixing ring 202 is provided on the outside of the connecting end of the pipe connector 2.

[0027] It is further explained that, since the high temperature resistant elastic sleeve 201 has a certain elasticity, it can connect and seal pipes of different diameters.

[0028] In a further embodiment, the pipe connector 2 is connected to the external pipe 4, and a second fixing ring 401 is provided on the outside of the external pipe 4 for use with the first fixing ring 202. The first fixing ring 202 and the second fixing ring 401 are connected by several groups of fixing bolts. Through the above scheme, the position of the connection between the external pipe 4 and the pipe connector 2 can be fixed.

[0029] according to Figure 1 and Figure 4-5 As shown, an electric sealing plate mechanism 3 is installed inside the boiler sealing body 1 for use therewith.

[0030] Specifically, the electric sealing plate mechanism 3 includes a sealing plate body 301, and the outer side of the sealing plate body 301 is covered with a sealing sleeve 3011, the sealing sleeve 3011 is provided with a number of evenly distributed annular tightening grooves, and the annular tightening grooves are provided with tightening belts 3012 that match them. The top of the sealing plate body 301 is connected to the movable plate 302, and the movable plate 302 moves in the movable groove opened in the installation groove 303. Two sets of rack plates 304 are installed on the top of the movable plate 302, and one end of the rack plate 304 passes through the outside of the installation groove 303 and engages with the gear 305. The gear 305 is installed on the outside of the rotating rod 306, and one end of the rotating rod 306 is connected to the drive motor 307.

[0031] Specifically, the installation groove 303 is communicated with the interior of the boiler seal body 1 , and the sealing plate body 301 moves within the installation groove 303 and the boiler seal body 1 .

[0032] Furthermore, when the sealing plate body 301 moves, the surface of the sealing plate body 301 will rub against the mounting groove 303 and the inner wall of the boiler seal body 1. By covering the sealing sleeve 3011 on the outside of the sealing plate body 301, the sealing sleeve 3011 can be used as an anti-wear medium to replace the friction between the outer surface of the sealing plate body 301 and the mounting groove 303 and the inner wall of the boiler seal body 1. The sealing sleeve 3011 is made of nitrile rubber. Nitrile rubber has extremely strong wear resistance and has a certain elasticity, so that the sealing sleeve 301 The rigid seal between 1 and the installation groove 303 and the inner wall of the boiler seal body 1 is transformed into a soft seal. This sealing method has a higher sealing degree and is less prone to wear. At the same time, the sealing sleeve 3011 is provided with a number of evenly distributed annular tightening grooves, and a matching tightening belt 3012 is provided in the annular tightening groove. The tightening belt 3012 is made of elastic material. The presence of the tightening belt 3012 can share the force borne by the sealing sleeve 3011 when it is deformed, avoiding elastic fatigue caused by long-term deformation of the sealing sleeve 3011, thereby extending the service life of the sealing sleeve 3011.

[0033] Specifically, a protective cover 3031 is provided on the top of the installation slot 303 , and the gear 305 is located inside the protective cover 3031 .

[0034] To further illustrate, the protective cover 3031 can protect the meshing portion between the gear 305 and the rack plate 304 .

[0035] In a further embodiment, a movable through slot for cooperating with the rack plate 304 is formed on the top of the installation slot 303 and the top of the protective cover 3031 .

[0036] In a further embodiment, an anti-rotation device is installed at the output end of the drive motor 307 to prevent the output end of the drive motor 307 from rotating. The anti-rotation device is a prior art and will not be described in detail.

[0037] When it is necessary to adjust the position of the sealing plate body 301 for opening and closing operations, the drive motor 307 is turned on. The drive motor 307 can drive the gear 305 to rotate through the rotating rod 306. Since the rack plate 304 is engaged with the gear 305, the rack plate 304 can be driven to move. Under the action of the movement of the rack plate 304, the movable plate 302 and the sealing plate body 301 are driven to move, thereby realizing the opening and closing operations.

[0038] The directions or positional relationships indicated by terms such as "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings.
