Description

Technical Field

[0001] This utility model relates to the field of hose technology, specifically to a high-temperature resistant silicone rubber hose. Background Technology

[0002] Rubber hoses are tubular rubber tubes used to transport gases, liquids, slurries, or granules.

[0003] The utility model with announcement number CN221723608U discloses a high-temperature resistant silicone rubber hose, including a silicone tube and further comprising: the silicone tube is made of silicone material, a rubber tube is fixedly sleeved on the outside of the silicone tube, an inner sleeve is fixedly sleeved on the outside of the rubber tube, a high-temperature resistant tube is fixedly sleeved on the outside of the inner sleeve, and a fixed sleeve is fixedly sleeved on the outside of the high-temperature resistant tube.

[0004] The above technical solution uses a silicone tube made of silicone material, followed by a rubber tube for protection, which ensures stable use and reduces the likelihood of breakage over long periods, thus improving the stability of the hose. An inner sleeve further encases the hose, followed by a high-temperature resistant tube for protection, and a fixing sleeve for secure positioning, enabling use in flame environments and enhancing its fire resistance and safety. However, in summer, prolonged exposure to high temperatures can damage the internal structure of the hose, and prolonged outdoor use can lead to aging and a lack of tensile strength, making it prone to breakage and affecting its longevity. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant silicone rubber hose to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-temperature resistant silicone rubber hose includes a rubber tube, an anti-corrosion sleeve on the inner wall of the rubber tube, a plurality of raised strips on the outer wall of the rubber tube, a reinforcing sleeve fitted on the outer wall of the rubber tube, a groove on the inner wall of the reinforcing sleeve corresponding to the raised strips, a braided mesh fitted on the outer wall of the reinforcing sleeve, and a wear-resistant shell fitted on the outer wall of the braided mesh.

[0008] Furthermore, the rubber tube is made of silicone rubber, and the inner diameter of the rubber tube is compatible with the outer diameter of the anti-corrosion sleeve.

[0009] In this invention, the silicone rubber material increases the flexibility of the rubber tube, and an anti-corrosion sleeve is installed inside the rubber tube to protect the inside of the tube and reduce the impact of the transported material on the rubber tube.

[0010] Specifically, the anti-corrosion sleeve is made of polypropylene, and the outer wall of the anti-corrosion sleeve is bonded and fixed to the inner wall of the rubber tube.

[0011] In this invention, the polypropylene material reduces the corrosive effect on the anti-corrosion sleeve when conveying aqueous solutions of inorganic salts, dilute or concentrated solutions of inorganic acids and alkalis. It also has the properties of being lightweight, high-strength and easy to form, thereby reducing the damage to the inner wall of the rubber tube caused by the conveyed substances.

[0012] Secondly, the convex strip is semi-cylindrical, the convex strips are distributed in a ring at equal intervals, and the rubber tube is a one-piece molded structure. The width of the inner wall of the groove is adapted to the width of the outer wall of the convex strip, and the convex strip and the groove are inserted into each other.

[0013] In this invention, the cooperation of multiple protrusions increases the contact area, and the protrusions increase the overall toughness of the rubber tube and its resistance to bending. The protrusions and grooves are inserted into each other, which increases the stability of the installation of the rubber tube and the reinforcing sleeve.

[0014] It should be noted that the outer diameter of the reinforcing sleeve is adapted to the inner diameter of the woven mesh, and the woven mesh is tightly bonded and fixed to the reinforcing sleeve.

[0015] In this invention, the woven mesh is made of nylon material, which improves the structural stability of the outer wall of the reinforcing sleeve, reduces the impact of bending on the reinforcing sleeve breakage, and thus increases the overall toughness.

[0016] Furthermore, the inner wall of the wear-resistant shell is provided with a number of support blocks, which are distributed at equal intervals. The outer ends of the support blocks are bonded and fixed to the inner wall of the wear-resistant shell, and the inner ends of the support blocks are bonded and fixed to the outer wall of the woven mesh.

[0017] In this invention, the wear-resistant shell increases the wear resistance of the outermost layer, and with the cooperation of multiple support blocks, it increases the stability of the gap between the wear-resistant shell and the woven mesh, reduces the deformation damage to the internal structure caused by external compression, and reduces the aging damage caused by long-term exposure to the external environment.

[0018] It is worth noting that the spaces between the support blocks are independent of each other, and the wear-resistant shell and the woven mesh are separated into several independent spaces.

[0019] In this invention, the combination of multiple independent spaces helps to provide thermal insulation and reduce the damage to the internal rubber tube caused by high external temperatures.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model increases the overall tensile strength by combining and bonding a rubber tube with multiple protruding strips with a reinforcing sleeve with grooves. The rubber tube is fitted with an anti-corrosion sleeve inside to reduce the erosion and damage to the inner wall of the rubber tube by substances. The woven mesh increases the toughness of the outer wall of the reinforcing sleeve and helps to resist bending. With the cooperation of a wear-resistant shell with multiple support blocks, the wear resistance of the outermost layer is increased, and the overall service life is extended.

[0022] 2. This utility model increases the stability of the gap between the wear-resistant shell and the woven mesh by setting multiple support blocks. The gap between the wear-resistant shell and the woven mesh is divided into several equally spaced independent spaces, reducing the impact of external environmental temperature changes on the internal rubber tube. With the cooperation of the wear-resistant shell, the aging effect caused by long-term exposure to the external environment is reduced. Attached Figure Description

[0035] 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.

[0036] Please see Figures 1-6 This embodiment provides a technical solution:

[0037] A high-temperature resistant silicone rubber hose includes a rubber tube 1, which is made of silicone rubber and the inner diameter of the rubber tube 1 is compatible with the outer diameter of the anti-corrosion sleeve 2.

[0038] In this invention, the silicone rubber material increases the flexibility of the rubber tube 1, and the anti-corrosion sleeve 2 is installed inside the rubber tube 1 to protect the inside of the rubber tube 1 and reduce the impact of the transported material on the rubber tube 1.

[0039] Furthermore, the inner wall of the rubber tube 1 is provided with an anti-corrosion sleeve 2. The rubber tube 1 is made of silicone rubber, and the inner diameter of the rubber tube 1 is compatible with the outer diameter of the anti-corrosion sleeve 2.

[0040] In this invention, the silicone rubber material increases the flexibility of the rubber tube 1, and the anti-corrosion sleeve 2 is installed inside the rubber tube 1 to protect the inside of the rubber tube 1 and reduce the impact of the transported material on the rubber tube 1.

[0041] Specifically, the outer wall of the rubber tube 1 is provided with several protrusions 10, and the outer wall of the rubber tube 1 is fitted with a reinforcing sleeve 3. The inner wall of the reinforcing sleeve 3 is provided with grooves 30 corresponding to the protrusions 10. The rubber tube 1 is made of silicone rubber, and the inner diameter of the rubber tube 1 is compatible with the outer diameter of the anti-corrosion sleeve 2.

[0042] In this invention, the silicone rubber material increases the flexibility of the rubber tube 1, and the anti-corrosion sleeve 2 is installed inside the rubber tube 1 to protect the inside of the rubber tube 1 and reduce the impact of the transported material on the rubber tube 1.

[0043] It should be noted that a braided mesh 4 is fitted on the outer wall of the reinforcing sleeve 3, and the rubber tube 1 is made of silicone rubber, with the inner diameter of the rubber tube 1 matching the outer diameter of the anti-corrosion sleeve 2.

[0044] In this invention, the silicone rubber material increases the flexibility of the rubber tube 1, and the anti-corrosion sleeve 2 is installed inside the rubber tube 1 to protect the inside of the rubber tube 1 and reduce the impact of the transported material on the rubber tube 1.

[0045] Furthermore, a wear-resistant shell 5 is fitted onto the outer wall of the woven mesh 4.

[0046] It should be noted that a number of support blocks 50 are provided on the inner wall of the wear-resistant shell 5. The support blocks 50 are distributed at equal intervals. The outer ends of the support blocks 50 are bonded and fixed to the inner wall of the wear-resistant shell 5, and the inner ends of the support blocks 50 are bonded and fixed to the outer wall of the woven mesh 4.

[0047] In this invention, the wear-resistant shell 5 increases the wear resistance of the outermost layer, and with the cooperation of multiple support blocks 50, it increases the stability of the gap between the wear-resistant shell 5 and the woven mesh 4, reducing the deformation damage to the internal structure caused by external compression. With the cooperation of the wear-resistant shell 5, the aging damage caused by long-term exposure to the external environment is reduced.

[0048] It is worth adding that the spaces between the support blocks 50 are independent of each other, and the wear-resistant shell 5 and the woven mesh 4 are separated into several independent spaces.

[0049] In this invention, the combination of multiple independent spaces helps to provide thermal insulation protection and reduce the damage to the internal rubber tube 1 caused by high external temperatures.

[0050] In this embodiment, when using the high-temperature resistant silicone rubber hose, the user first inserts the rubber hose 1 with the anti-corrosion sleeve 2 into the groove 30 on the reinforcing sleeve 3 through multiple protrusions 10. Then, the braided mesh 4 is bonded and fixed to the outer wall of the reinforcing sleeve 3, and the wear-resistant shell 5 with the support block 50 is bonded and fixed to the outer side of the braided mesh 4. The space between adjacent support blocks 50 is independent of each other and has heat insulation and high heat performance.

[0051] When pipes need to be connected, the two ends of the rubber tube 1 are welded and fixed to the corresponding pipes. With the help of the braided mesh 4, the outer side of the reinforcing sleeve 3 is strengthened to resist bending. With the help of multiple support blocks 50, the wear-resistant shell 5 is made wear-resistant and heat-insulating, reducing the impact of external height on the material transported by the internal rubber tube 1. The wear-resistant shell 5 reduces the aging damage caused by wind and sun exposure in the external environment, extending the overall service life. The rubber tube 1 is made of corner material to increase the overall flexibility.
