Description

Technical Field

[0001] The utility model belongs to the technical field of silicone sleeves, and in particular relates to a high-temperature resistant silicone sleeve. Background Art

[0002] Silicone tubes are carriers for the circulation and coating of liquids, gases and other materials. Common silicone tubes include: medical silicone tubes, food-grade silicone tubes, industrial silicone tubes, special-shaped silicone tubes, silicone tube accessories. Medical silicone tubes are mainly used for medical device accessories; food-grade silicone tubes are used for water dispensers, coffee machine diversion pipes, and waterproof circuit protection for household appliances. Industrial silicone tubes are used for the circulation of special chemical, electrical and other special environmental protection carriers, and use special performance silicone.

[0003] The existing silicone sleeves have poor extrusion resistance. Since the silicone sleeves are squeezed against each other during transportation, the tube body is flattened and deformed, which affects the normal use of the silicone sleeves. Utility Model Content

[0004] The utility model aims to provide a high temperature resistant silicone sleeve to solve the technical problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a high-temperature resistant silicone sleeve, including a tube body, the tube body including an inner tube and an outer tube located outside the inner tube, the inner wall of the inner tube is provided with a reinforcement layer, there is a spacing between the inner tube and the outer tube, and the outer surface of the inner tube and the inner surface of the outer tube are connected by an annular reinforcement member, and a reinforcement cavity is formed between the reinforcement member and the outer surface of the inner tube and the inner surface of the outer tube, and a fireproof strip is provided in each of the reinforcement cavities.

[0006] Preferably, the inner tube and the outer tube are both made of phenyl silicone rubber, and the outer surface of the outer tube is provided with an anti-corrosion coating.

[0007] Preferably, the reinforcement layer is made of multiple layers of aramid fiber cloth into a tubular structure.

[0008] Preferably, the reinforcement member is formed by a plurality of reinforcement plates connected end to end, and a V-shaped structure is formed between every two adjacent reinforcement plates.

[0009] Preferably, the outer surface of the inner tube and the inner surface of the outer tube are provided with a plurality of grooves distributed in a circular array, and the connection between each two adjacent reinforcing plates is provided with convex strips distributed one-to-one with the grooves, and the size of the convex strips is consistent with the size of the grooves.

[0010] Preferably, the fireproof strip is a cylindrical structure, and is made of fireproof foam silicone rubber.

[0011] The high temperature resistant silicone casing of the utility model has the following advantages:

[0012] 1. The utility model forms a plurality of annular, stable triangular structures between the reinforcing plate and the inner tube and the outer tube by setting the reinforcing member, thereby effectively preventing the phenomenon of the tube body being flattened and deformed due to extrusion, greatly enhancing the strength of the tube body and extending its service life. The cooperation between the convex strip and the groove plays a good limiting role on the reinforcing member, so that the reinforcing member will not move arbitrarily inside the tube body, thereby improving the stability of the structure.

[0013] 2. The inner tube and the outer tube are made of phenyl silicone rubber, so that the silicone sleeve can withstand a high temperature of 250°C. By using aramid fiber cloth as a reinforcement layer, the silicone sleeve has good heat resistance and reinforcement effects. Through the setting of fireproof strips, as the temperature rises, the foam silicone rubber will be ceramicized, so that the tube body has good fireproof and heat-insulating functions and strong safety.
