Description

Anti-static ignition automobile fuel pipe

Technical Field

The utility model relates to an automobile oil piping system especially relates to a prevent car fuel pipe that static is on fire.

Background

The automobile fuel pipe comprises a fuel oil conveying pipe and a fuel oil pipe for supplying fuel to an engine, and is an important safety part mainly used for providing a gasoline circulation pipeline, along with the improvement of the requirements of fuel oil evaporation emission regulations, the permeability and the strength of the fuel oil pipe are improved, along with the departure of the national six policy and the development of oil-electricity hybrid automobiles, the emission limit of automobile exhaust pollutants is more strict, the existing fuel oil pipe cannot meet the requirements of fuel oil evaporation emission, and the existing fuel oil pipe is not conductive, so that the electrostatic ignition of the fuel oil is easily caused.

Disclosure of Invention

The utility model provides a solve above-mentioned problem, provide a hyposmosis fuel prevent car that static is on fire and fires burning oil pipe.

The utility model discloses the technical scheme who takes:

the utility model provides an automobile fuel pipe of antistatic fire, its by inside outside include inlayer, middle level and skin in proper order, wherein the inlayer is NBR material conducting layer, and the middle level is the THV material layer, and the skin is the CSM material layer, sets up the weaving layer between middle level and skin.

The inner layer and the middle layer are provided with a first bonding layer, and the middle layer and the weaving layer are provided with a second bonding layer.

The first bonding layer and the second bonding layer are NBR material layers.

The utility model has the advantages that: the utility model discloses an inlayer is the NBR conducting layer, and inlayer and fuel contact avoid arousing fuel static to catch fire, and the middle level is the fluororesin barrier layer for satisfying six emission standard in the country and setting up, and the outer layer has good ageing-resistant, ozone resistance's protective layer, has increased the life of burning oil pipe, and outer inboard weaving layer improves the pressure resistance of burning oil pipe.
