Description

Technical Field

[0001] This utility model relates to the field of duct flange technology, specifically a duct flange with a built-in sealing gasket. Background Technology

[0002] When installing existing duct flanges, a sealing gasket needs to be placed between the two flanges to achieve a seal when the ducts are connected.

[0003] The above installation process has a low degree of standardization. First, manual installation is unstable and prone to displacement. Second, the installation efficiency is too low, which affects the construction period. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a duct flange with a built-in sealing gasket.

[0005] This utility model provides the following technical solution:

[0006] A duct flange with a built-in sealing gasket includes a thermal insulation profile and a sealing gasket, wherein the sealing gasket and the thermal insulation profile are integrally formed by soft and hard co-extrusion.

[0007] When two flanges are connected and fixed, the sealing gaskets on the two flanges are pressed against each other from top to bottom.

[0008] Preferably, the thermal insulation profile is made of PP material and the sealing gasket is made of TPE material.

[0009] Preferably, the sealing gasket has a flat sheet structure under normal conditions.

[0010] Preferably, the two ends of the sealing gasket are integrally connected to the thermal insulation profile, and the middle of the sealing gasket has an outwardly convex arc-shaped structure.

[0011] Preferably, the end face of the thermal insulation profile forms a downward recessed structure.

[0012] Compared with existing technologies, this utility model provides a duct flange with a built-in sealing gasket. During the production stage, the sealing gasket and insulating profile are integrally molded, allowing it to be "pre-installed" on the flange. This solves the problem of complex manual gasket installation during later construction and enables the production of standard parts, improving product quality. The ordering and production processes are optimized while adhering to installation methods. Attached Figure Description

[0014] Figure 2 This is a schematic diagram of the overall structure of the present utility model. Figure 2 . Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please refer to the figure for a duct flange with a built-in sealing gasket. Figure 1 As shown, the thermal break duct flange mainly includes metal profiles (3, 4) and the middle thermal insulation profile 1. Usually, the thermal insulation profile 2 is made of plastic material and integrally formed by mold.

[0017] The concept of this utility model is to integrally form a sealing gasket 2 on the end face of a thermal insulation profile through a soft-hard co-extrusion process. For example, the thermal insulation profile 1 is made of PP material, and the sealing gasket 2 is made of TPE material.

[0018] In the specific design, two methods are adopted, such as Figure 1 As shown, the thermal insulation profile 2 and the sealing gasket 2 are completely fitted together. Furthermore, the sealing gasket 2 has a flat, sheet-like structure, and the two are integrally molded. Figure 2 As shown, the two ends of the sealing gasket 2 are integrally connected to the heat insulation profile 1, the middle part of the sealing gasket 2 has an outward convex arc structure, and the end face of the heat insulation profile 1 forms a downward concave structure.

[0019] Figure 1 The structure allows the gaskets to be pressed together when the two flanges are joined, forming a tight seal that extends to both sides. Figure 2 The structure also prevents the gasket 2 from shifting or wrinkling when the two flanges are joined. In addition, theoretically, the thickness of the middle part of the gasket 2 can be made greater to improve the stability of the installation and the sealing effect.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
