Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a wear-resistant and corrosion-resistant rubber pipe. Background Art

[0002] In modern industrial production, rubber hoses are widely used in the transportation of liquids and gases. Rubber hoses have the advantages of being bendable, easy to set up, and able to transport corrosive substances. However, in some use environments, the outside of the rubber hose may come into contact with objects moving relative to it or be squeezed and stepped on, which makes the outer wall of the rubber hose prone to wear and deformation, affecting the service life of the pipeline and the normal transportation of the fluid, and even causing leakage of the transported substances. Improving the corrosion resistance and wear resistance of rubber hoses can improve the quality and safety of rubber hoses. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1 to Figure 5As shown, a wear-resistant and corrosion-resistant rubber tube comprises a double corrosion-resistant rubber layer 1, a middle reinforcement layer 2 is arranged in the middle of the double corrosion-resistant rubber layer 1, the middle reinforcement layer 2 is a glass fiber mesh or nylon mesh with a thickness of 0.2mm to 0.8mm, which plays a reinforcement role and improves the overall tensile resistance and flexibility of the rubber tube. The distance from the middle reinforcement layer 2 to the inner wall of the double corrosion-resistant rubber layer 1 is greater than the distance from the middle reinforcement layer 2 to the outer wall of the double corrosion-resistant rubber layer 1, that is, the rubber tube layer in the middle reinforcement layer 2 is thicker, and the service life is long when corrosive liquids or gases are transported and circulated in the tube.

[0021] Although rubber itself has a certain wear resistance, it is still not suitable for some high-wear applications. Therefore, in order to significantly improve the wear resistance of the rubber tube without affecting the bending of the rubber tube, a wear-resistant spiral ring 3 is provided outside the double corrosion-resistant rubber layer 1. The hardness of the wear-resistant spiral ring 3 is greater than that of the double corrosion-resistant rubber layer 1. Figure 5 Protruding wear-resistant sleeves 3a are evenly arranged outside the wear-resistant spiral ring 3 at equal intervals. The wear-resistant sleeves 3a are not arranged throughout the head and tail of the entire wear-resistant spiral ring 3, but are targeted at the most severely worn parts; the wear-resistant spiral ring 3 is made of rolled metal wire, and the cross-section of the metal wire is circular or rectangular. The wear-resistant sleeves 3a are evenly arranged outside the metal wire, and the hardness of the material is greater than that of the metal wire. The wear-resistant sleeves 3a and the outside of the metal wire are both provided with a coating to improve wear resistance and corrosion resistance.

[0022] The wear-resistant spiral ring 3 and the double corrosion-resistant rubber layer 1 are connected by Figure 3 , Figure 4 The butt plug sleeve 4 shown is connected, and the butt plug sleeve 4 includes an inner ring 4a connected to the double corrosion-resistant rubber layer 1 and an outer ring 4b connected to the wear-resistant spiral ring 3. The outer ring 4b is flush with the outer periphery of the wear-resistant spiral ring 3, and the butt surface of the inner ring 4a and the outer ring 4b is an inclined surface. The outer wall of the inner ring 4a is provided with a slot, and the inner wall of the outer ring 4b is provided with a spline matching the slot. A butt plug sleeve 4 is provided at each end of the wear-resistant spiral ring 3. The side of the outer ring 4b with a larger thickness is connected to the wear-resistant spiral ring 3, and the inner ring 4a is away from the wear-resistant spiral ring. One side of the ring 3 is relatively thick. In summary, the docking sleeve 4 not only connects the wear-resistant spiral ring 3 and the double corrosion-resistant rubber layer 1, but also when it is necessary to adjust the position of the wear-resistant spiral ring 3 relative to the double corrosion-resistant rubber layer 1, the wear-resistant spiral ring 3 can be compressed to separate the inner ferrule 4a and the outer ferrule 4b. The connector of the outer ferrule 4b and the wear-resistant spiral ring 3 can be rotated relative to the double corrosion-resistant rubber layer 1, and the wear-resistant sleeve 3a with the strongest wear resistance can be targetedly set at the most worn position during use. This effectively improves the overall wear resistance of the pipe and extends its service life.

[0023] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, any changes, modifications or additions should fall within the protection scope of the utility model.
