Description

Technical Field

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

[0002] With the gradual development of the domestic automobile industry, people are paying more and more attention to the quality of automobiles, making the quality of auto parts increasingly important. Currently, the rubber hoses inside engines on the market have poor oil resistance, weak high-temperature resistance, and low pressure resistance. At the same time, rubber hoses are prone to cracking, aging, and damage, which can lead to fuel leaks. In severe cases, high-temperature fuel can be sprayed out, causing a fire and posing a certain safety hazard to the occupants of the vehicle.

[0003] To address these issues, we propose a new type of high-temperature resistant rubber hose. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a novel high-temperature resistant rubber hose, the specific solution of which is as follows: A novel high-temperature resistant rubber hose includes a hose body with hose connectors at both ends. The hose body includes an inner rubber layer with a high-temperature resistant coating on its inner side, and a reinforcing layer, a middle rubber layer, and a wear-resistant layer sequentially on its outer side. The hose connector includes an end with an annular groove for the hose body and a limiting groove. A slider slides within the limiting groove, and a threaded through hole is provided on the slider. A positioning screw for fixing the hose body is screwed into the threaded through hole. A travel groove extending to the annular groove is formed at the bottom of the limiting groove. A fastening sleeve for adjusting the position of the positioning screw is also screwed into the end.

[0005] Based on the above, the inner circumference of the end is provided with connecting threads.

[0006] Based on the above, a sealing ring is provided inside the annular groove.

[0007] Based on the above, the material of the high-temperature resistant coating is ZS-811 organic anti-corrosion coating.

[0008] Based on the above, the wear-resistant layer is made of polychlorotrifluoroethylene.

[0009] Based on the above, the material of the inner rubber layer is nitrile rubber.

[0010] Based on the above, the material of the middle rubber layer is neoprene rubber, and the middle rubber layer partially enters the reinforcing layer.

[0011] Based on the above, the reinforcing layer is made of a mixture of steel wire and nylon thread woven together.

[0012] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages: The novel high-temperature resistant rubber pipe provided by this utility model has a structural design that not only has good high-temperature resistance and wear resistance, but also good structural strength and antibacterial properties, ensuring the service life of the water supply pipe. The structural design is ingenious and practical. Attached Figure Description
