Description

Technical Field

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

[0002] Fuel pipes are mainly used to transport gasoline, diesel and other fuels. They have the characteristics of high and low temperature resistance, aging resistance, corrosion resistance, and pressure resistance. They are roughly divided into fuel hard pipes and fuel hoses, and are usually high-pressure pipes. Common fuel hoses are mainly made of rubber materials such as AEM, ECO, and NBR.

[0003] Existing fuel pipelines are usually divided into hoses and hard pipes. Hoses are more flexible and can absorb vibrations, while hard pipes are more resistant to pressure and wear but less flexible and not easy to bend and install. Existing fuel hoses usually increase the wall thickness of the fuel pipeline to increase the wear resistance of the pipeline, but it only makes it take more time for the pipeline to crack, but the essence of the pipeline has not changed and it is still prone to wear. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a wear-resistant fuel oil pipe to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a wear-resistant fuel oil pipe, including an oil pipe body, a hard wear-resistant sleeve is connected to the outer surface of the oil pipe body, soft wear-resistant sleeves are connected to both sides of the oil pipe body, and wear-resistant rings are sleeved on the outside of the soft wear-resistant sleeves.

[0006] By adopting the above technical solution, the hardness of the hard wear-resistant sleeve is higher than that of the rubber fuel pipe, so the material itself is more wear-resistant. At the same time, multiple hard wear-resistant sleeves are connected by soft wear-resistant sleeves to prevent the hard wear-resistant sleeves from affecting the bending of the oil pipe body, and the several wear-resistant rings outside the soft wear-resistant sleeve can reduce the contact between other objects and the soft wear-resistant sleeve, and the wear-resistant rings will bear the wear instead.

[0007] Furthermore, the hard wear-resistant sleeve and the soft wear-resistant sleeve are provided in plurality, and the plurality of hard wear-resistant sleeves and the soft wear-resistant sleeves are distributed at equal distances.

[0008] By adopting the above technical solution, multiple hard wear-resistant sleeves are connected by soft wear-resistant sleeves, so that the hard wear-resistant sleeves are prevented from affecting the bending of the oil pipe body.

[0009] Furthermore, the soft wear-resistant sleeve is made of rubber material.

[0010] By adopting the above technical solution, when the oil pipe body is bent, the gap between the two hard wear-resistant sleeves increases, and the oil pipe body is prevented from being worn by the soft wear-resistant sleeve.

[0011] Furthermore, the hard wear-resistant sleeve and the wear-resistant ring are both made of PVC material.

[0012] By adopting the above technical solution, the hardness of the hard wear-resistant sleeve and the wear-resistant ring is higher than that of the rubber fuel pipe, so the material itself is more wear-resistant.

[0013] Furthermore, the wear-resistant rings are provided in multiple groups, multiple wear-resistant rings form one group, and the multiple wear-resistant rings are distributed at equal distances.

[0014] By adopting the above technical solution, the several wear-resistant rings outside the soft wear-resistant sleeve can reduce the contact between other objects and the soft wear-resistant sleeve, and the wear-resistant rings bear the wear instead.

[0015] Furthermore, the oil pipe body includes a base layer, and the inner circle of the base layer is provided with an antistatic layer, the inner circle of the antistatic layer is provided with an anti-corrosion layer, the outer circle of the base layer is provided with a flame retardant layer, and the outer circle of the flame retardant layer is provided with a thermal insulation layer.

[0016] By adopting the above technical scheme, the anti-corrosion layer is provided to avoid corrosion of the inner wall of the oil pipe body, the anti-static layer is provided to avoid static electricity from igniting the fuel in the oil pipe body, the flame retardant layer is provided to increase the difficulty of catching fire of the oil pipe body, and the thermal insulation layer is provided to reduce the impact of external high and low temperatures on the fuel.

[0017] Furthermore, both ends of the oil pipe body are connected with joints.

[0018] By adopting the above technical solution, the staff can install the joint on the equipment to enable the oil pipe body to transport fuel.

[0019] Furthermore, the outer ring of the thermal insulation layer is provided with a buffer layer, and the outer ring of the buffer layer is provided with a wear-resistant layer.

[0020] By adopting the above technical solution, the pressure exerted on the oil pipe body by the external pressure is reduced by setting the buffer layer, and the wear resistance of the oil pipe body is increased by setting the wear-resistant layer.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] The utility model arranges a hard wear-resistant sleeve, a wear-resistant ring and a soft wear-resistant sleeve. The hard wear-resistant sleeve is harder than a rubber fuel pipe, so the material itself is more wear-resistant. At the same time, a plurality of hard wear-resistant sleeves are connected by the soft wear-resistant sleeve to avoid the hard wear-resistant sleeves affecting the bending of the fuel pipe body. The several wear-resistant rings outside the soft wear-resistant sleeve can reduce the contact between other objects and the soft wear-resistant sleeve, and the wear is borne by the wear-resistant rings instead. The wear resistance of the fuel pipe is effectively increased, and the flexibility of the fuel pipe is less affected. BRIEF DESCRIPTION OF THE DRAWINGS
