Embodiment 1

[0019] The thickness of the fluorine rubber inner layer 1 is set to 5.0-7.0 mm, its fuel resistance and high temperature resistance are better than the commonly used nitrile rubber, and the adjustment of its thickness can ensure the thickness of the fuel pipe.

Embodiment 2

[0021] The thickness of the chlorosulfonated polyethylene outer layer 4 is 7.0-9.0 mm. Furthermore, the thickness of the chlorosulfonated polyethylene outer layer 4 is designed to be 7.5 mm, so as to reduce the cost while ensuring the thickness of the fuel pipe.

[0022] When the present invention is in use, by improving the structure of the reinforcing layer 3 in the fuel pipe, the anti-seepage capability of the fuel pipe is improved and the permeability is reduced. Its technical route is mainly by setting the upper and lower layers of the reinforcing layer 3 as the braided layer 31, and setting the epichlorohydrin rubber layer 32 in the middle of the braided layer 31, and adjusting the thickness between the braided layer 31 and the epichlorohydrin rubber layer 32, Improve the mechanical strength of the reinforcing layer 3 and enhance the anti-seepage ability; and optimize the thickness of the fluororubber inner layer 1 and the chlorosulfonated polyethylene outer layer 4, so ...

Abstract

The invention discloses a novel low-permeability-rate knitting fuel oil pipe which comprises a fluororubber inner layer, a chlorosulfonated polyethylene middle layer, a reinforcing layer and a chlorosulfonated polyethylene outer layer. The reinforcing layer comprises knitting layers and an epichloro-hydrin rubber layer. The epichloro-hydrin rubber layer is arranged between the two knitting layers. Aramid wire knitting layers are adopted as the knitting layers. The thickness of the knitting layers is 0.5 mm. The thickness of the fluororubber inner layer ranges from 5.0 mm to 7.0 mm. The thickness of the chlorosulfonated polyethylene outer layer ranges from 7.0 mm to 9.0 mm. The fuel oil pipe is simple in structure and convenient to use, the permeability rate is remarkably reduced, and fuel oil is saved.

Description

technical field [0001] The invention relates to the technical field of fuel pipes for automobiles, in particular to a novel braided fuel pipe with low permeability. Background technique [0002] In recent years, with the rapid development of economy, countries all over the world have gradually realized the tension of energy and the negative impact of economic development on the global environment. Therefore, countries all over the world are investing more and more in energy conservation and environmental protection. As people become richer and richer, many families already have their own family cars, fuel pipe leakage is a common problem, which is not only related to the use of automobile power machines, but also has a certain relationship with the quality of the fuel pipe itself . With the continuous improvement of fuel emission standards in various countries, more and more attention has been paid to the penetration of fuel pipes. [0003] Therefore, due to the above-men...
