Description

Technical Field

[0001] This utility model belongs to the technical field of ventilation duct fabric, specifically relating to the air-leakage prevention inner and outer protective lining structure of ventilation duct fabric. Background Technology

[0002] "Air-Leak-Proof Inner and Outer Protective Lining Structure for Ventilation Duct Fabric" refers to a structural design applied to ventilation duct fabric. Ventilation duct fabric is commonly used in ventilation and other fields, and air leakage prevention is a crucial performance requirement. This structure, by incorporating inner and outer protective linings, aims to enhance the ventilation duct fabric's ability to prevent air leakage. Through the synergistic effect of the two protective layers, it effectively reduces or prevents air leakage from gaps and other locations within the ventilation duct fabric, improving the efficiency and stability of ventilation. It is applicable to scenarios such as mine ventilation and tunnel ventilation.

[0003] Traditional ventilation duct leakage detection suffers from problems such as low ventilation efficiency and high operating costs. Utility Model Content

[0004] The purpose of this utility model is to provide an inner and outer protective lining structure for preventing air leakage in ventilation ducts, so as to solve the problems of low ventilation effect and high operating cost in the above-mentioned background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air duct fabric anti-leakage inner and outer protective lining structure, including an air bag body and a connecting air bag;

[0006] The main body of the air bag and the connection point connecting the air bag are respectively provided with connecting zippers;

[0007] An outer protective liner is provided on the outside of the side of the air bag body connected to the zipper, an inner protective liner is provided on the inside of the side of the air bag connected to the zipper, and an adhesive layer is provided on the inside of one end of the outer protective liner body.

[0008] Preferably, the inner protective liner and the outer protective liner body are connected by hot-melt welding to the air bag and the air bag body, respectively.

[0009] Preferably, the main body of the air bag is connected to the air bag via a connecting zipper, and the inner protective liner and the outer protective liner are respectively wrapped with the connecting zipper.

[0010] Preferably, the outer protective liner and the inner protective liner are both made of environmentally friendly polyester fiber material, and the air bag body and the other side of the air bag are connected by a zipper connection.

[0011] Compared with the prior art, this utility model provides an inner and outer protective lining structure for preventing air leakage in the ventilation duct, which has the following beneficial effects:

[0012] 1. A connecting zipper is used to connect the main body of the air bag to the connecting air bag. This zipper connection method is simple and convenient to operate, and compared with traditional sewing and gluing methods, it greatly shortens the installation and disassembly time. It can effectively improve work efficiency when a ventilation system needs to be quickly set up or when the air bag needs to be replaced or repaired.

[0013] 2. This device can flexibly combine air bags of different lengths or functions according to the ventilation needs of different scenarios. For example, in mines, different roadways have different lengths. By connecting the main body of the air bag and the connecting air bag with different lengths by zipper, the ventilation length requirements of different roadways can be met. Or, when it is necessary to add functions such as filtration and humidification, the corresponding air bags can be connected, which improves the flexibility and adaptability of the use of the ventilation duct cloth.

[0014] 3. The inner and outer protective linings are each wrapped with a connecting zipper, and an adhesive layer is provided inside one end of the outer protective lining. The adhesive layer uses high-strength, high-adhesion silicone rubber pressure-sensitive adhesive combined with a fiber reinforcement layer. It can maintain its adhesion in a wide range of temperature environments, has extremely strong adhesion to various material surfaces, and can withstand high air pressure. This effectively prevents external air from seeping in or internal air from leaking out, ensuring the airtightness of the duct fabric during use and reducing the problem of reduced ventilation efficiency caused by air leakage.

[0020] 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.

[0021] This utility model provides, for example Figure 1-4 The air duct fabric leak-proof inner and outer protective lining structure shown includes the air bag body 1 and the connecting air bag 2.

[0022] The air bag body 1 and the air bag 2 are respectively provided with connecting zippers 5. An outer protective liner body 3 is provided on the outside of the air bag body 1 on the side connected to the zipper 5. An inner protective liner 4 is provided on the inside of the side of the air bag 2 connected to the zipper 5. An adhesive layer 6 is provided on the inside of one end of the outer protective liner body 3.

[0023] like Figure 1-4 As shown, the inner protective liner 4 and the outer protective liner body 3 are connected to the air bag 2 and the air bag body 1 by hot melt welding. The air bag body 1 is connected to the air bag 2 by a connecting zipper 5. The inner protective liner 4 and the outer protective liner body 3 are wrapped with the connecting zipper 5. The outer protective liner body 3 and the inner protective liner 4 are made of environmentally friendly polyester fiber material. The air bag body 1 and the connecting air bag 2 are connected on the other side by a zipper.

[0024] In this embodiment, during actual use, the user connects the main body 1 of the air bag and the connecting air bag 2 via a connecting zipper 5. This zipper connection method facilitates quick installation and disassembly, and allows for flexible combination of air bags of different lengths or functions to meet the ventilation needs of different scenarios. After connection, the air duct fabric can serve as a ventilation duct in places requiring ventilation, such as mines and tunnels, transporting air from one end to the other to achieve air circulation and ventilation. During ventilation, the basic structure composed of the main body 1 of the air bag and the connecting air bag 2 is crucial to ensuring the ventilation function. Its material itself possesses a certain degree of sealing and strength, capable of withstanding a certain wind pressure and maintaining the normal operation of the ventilation system.

[0025] Preferably, the adhesive layer 6 is made of high-strength, high-adhesion silicone rubber pressure-sensitive adhesive, combined with a fiber reinforcement layer. The silicone rubber pressure-sensitive adhesive has excellent weather resistance and temperature resistance, maintaining its adhesion in environments ranging from -40℃ to 200℃, and exhibits strong adhesion to various material surfaces such as metals and fabrics. The fiber reinforcement layer further enhances the tensile strength and tear resistance of the adhesive layer 6. After connecting the air bag body 1 and the connecting air bag 2 via the connecting zipper 5, the user attaches the adhesive layer 6 of the outer protective liner body 3 to the connecting air bag 2 body 1, pressing firmly to ensure full contact of the adhesive layer 6, thus forming a strong seal and effectively preventing external air infiltration or internal air leakage.

[0026] During normal use of the air bag, if air leaks at the connecting zipper 5, the air pressure inside the air duct will compress the inner protective liner 4 and the outer protective liner 3, making them fit tightly against the connecting zipper, thereby preventing air leakage from the connecting zipper.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
