These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0027] According to an embodiment of the present invention, an internal sealing flange that is easy to disassemble is provided.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the easily disassembled inner sealing flange according to an embodiment of the present utility model includes a flange 1, a connecting pipe 2 at the top of flange 1, a fixing component 3 symmetrically arranged on the outer circumference of flange 1, a sealing ring 4 at the inner bottom of flange 1, a flange 2 5 at the bottom of flange 1, and flange 2 5 cooperates with flange 1 through an installation component 6. A sealing element 7 that cooperates with sealing ring 4 is provided at the inner top of flange 2 5, and a connecting pipe 2 8 is provided at the bottom of flange 2 5.

[0029] By utilizing the above-described technical solution of this utility model, the installation and disassembly process of the inner sealing flange is simplified by setting the fixing component 3, reducing maintenance needs caused by unstable connections and lowering maintenance costs. Simultaneously, the fixing component 3 ensures a tight connection, effectively preventing accidental rotation of flange 1 and enhancing the stability of the inner sealing flange. By setting the installation component 6, rapid installation and disassembly of flange 1 are achieved, simplifying operation, significantly shortening operation time, and improving work efficiency.

[0030] In one embodiment, for the sealing ring 4, a sealing limiting ring 9 is provided at the bottom end of the sealing ring 4, and a sealing limiting groove 10 that cooperates with the sealing limiting ring 9 is provided at the top end of the sealing member 7, thereby providing excellent sealing effect for the inner sealing flange and effectively preventing media leakage.

[0031] In one embodiment, the fixing component 3 includes a fixing seat 301 disposed on the outer circumference of flange 1. Fixing block 1 302 and fixing block 2 303 are respectively disposed at both ends of the fixing seat 301. A pressing rod 304 is disposed in the middle of fixing block 1 302, and a pressing groove 305 that cooperates with the pressing rod 304 is opened in the middle of fixing block 2 303. A through hole 306 is opened in the middle of the fixing seat 301, and a spring 1 307 is disposed inside the through hole 306. A fixing post 308 is disposed inside the spring 1 307, and the fixing post 308 passes through the through hole 306 and cooperates with the pressing rod 304. A buckle 3031 is disposed on one side of the top of fixing block 2 303, and a groove 3032 that cooperates with the buckle 3031 is disposed on the other side of the top of fixing block 2 303. This simplifies the installation and disassembly process of the inner sealing flange, reduces maintenance needs due to unstable connections, and lowers maintenance costs.

[0032] The working principle of the fixing component 3 is as follows: When it is necessary to fix flange 1 and flange 2 5, the pressing rod 304 is pressed to apply pressure to the fixing post 308, thereby achieving a fixed connection between the fixing post 308 and the fixing groove 11. After the fixing post 308 is fixed, the pressing rod 304 is further fixed in the pressing groove 305 by the mutual cooperation between the buckle 3031 and the groove 3032, so as to prevent the fixing post 308 from separating from the fixing groove 11, avoid the flange 1 from rotating, and ensure the stability and fixing effect of the inner sealing flange. When it is not necessary to fix flange 1 and flange 2 5, the buckle 3031 is rotated to make the buckle 3031 and the groove 3032 lose their cooperation. The fixing post 308 is released from the fixing groove 11 under the elastic force of the spring 307, thereby improving the convenience and operation efficiency of the inner sealing flange.

[0033] In one embodiment, for the flange 2 5, a plurality of fixing grooves 11 are provided on the outer circumference of the flange 2 5, and the fixing grooves 11 cooperate with the fixing post 308, thereby ensuring the tightness of the connection, effectively preventing the accidental rotation of the flange 1, and enhancing the stability of the inner sealing flange.

[0034] In one embodiment, the mounting assembly 6 includes a mounting groove 601 formed at the top of the flange 1, a spring 602 provided at the bottom of the mounting groove 601, and several sliding grooves 603 formed on both sides of the inner wall of the mounting groove 601, thereby enabling the rapid installation and disassembly of the flange 1 and improving work efficiency.

[0035] In one embodiment, for the flange 1, the bottom end of the flange 1 is provided with an installation ring 12 that cooperates with the installation groove 601, and the bottom end of the installation ring 12 is provided with a sliding block 13 that cooperates with the sliding groove 603, thereby facilitating the installation and disassembly of the inner sealing flange and greatly shortening the operation time.

[0036] The working principle of the mounting component 6 is as follows: When flange 1 and flange 5 need to be installed, flange 1 slides through the cooperation of sliding block 13 and sliding groove 603. Sliding block 13 slides into the interior of fixed groove 11, compressing spring 2 602. Rotating flange 1 causes sliding block 13 to rotate, causing sliding block 13 to lose its cooperation with sliding groove 603, thereby realizing the installation of the inner sealing flange. When flange 1 and flange 2 5 need to be disassembled, rotating flange 1 causes sliding block 13 to rotate. Sliding block 13 rotates into the interior of fixed groove 11, and under the elastic action of spring 2 602, sliding block 13 slides outward inside sliding groove 603, causing flange 1 and flange 2 5 to lose their cooperation, thus realizing the disassembly of the inner sealing flange. The operation is simple and improves work efficiency.

[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0038] In practical applications, when flange 1 and flange 2 5 need to be installed, flange 1 is moved above flange 2 5, and the initial connection between flange 1 and flange 2 5 is achieved through the installation component 6 (the working principle of the installation component 6 is as described above). After the connection is completed, flange 1 and flange 2 5 are further fixed by the fixing component 3 (the working principle of the fixing component 3 is as described above), preventing flange 1 from rotating and ensuring the stability and fixing effect of the inner sealing flange. When flange 1 and flange 2 5 need to be disassembled, the fixing post 308 is disengaged from the fixing groove 11 by rotating the buckle 3031, releasing the fixing state of flange 1 and flange 2 5. Then, by rotating flange 1, the sliding block 13 slides out of the installation groove 601, realizing the rapid separation of flange 1 and flange 2 5 and improving the working efficiency of the inner sealing flange. In addition, the cooperation between the sealing limit ring 9 and the sealing limit groove 10 can provide excellent sealing effect, effectively preventing media leakage and achieving the sealing performance of the inner sealing flange.

[0039] In summary, by utilizing the above-mentioned technical solution of this utility model, the installation and disassembly process of the inner sealing flange is simplified by setting the fixing component 3, reducing maintenance needs caused by unstable connections and lowering maintenance costs. Simultaneously, the fixing component 3 ensures a tight connection, effectively preventing accidental rotation of flange 1 and enhancing the stability of the inner sealing flange. By setting the installation component 6, rapid installation and disassembly of flange 1 are achieved, simplifying operation, significantly shortening operation time, and improving work efficiency. Furthermore, the cooperation between the sliding block 13 and the fixing groove 11 effectively prevents accidental loosening or detachment of the inner sealing flange during use, ensuring connection safety. Through the mutual cooperation of the sealing limiting ring 9 and the sealing limiting groove 10, excellent sealing performance is provided for the inner sealing flange, effectively preventing media leakage, ensuring the safety and reliability of the inner sealing flange, reducing downtime and maintenance time caused by leakage or poor sealing, and improving overall operating efficiency.
