Abstract
The utility model provides a low permeability oil filling pipe which is composed of an outer nitrile butadiene rubber layer and an inner polrvinyl chloride layer. Thickness ratio of the outer nitrile butadiene rubber layer and the inner polrvinyl chloride layer is 0.7: 0.3. The low permeability oil filling pipe has the advantages of being simple in structure, reliable in property, capable of substantially improving low temperature resistance and elasticity of the oil filling pipe, and effectively reducing cost.
Description
Technical field
The utility model relates to the rubber product field, especially relates to a kind of automobile hyposmosis oil filling pipe.
Background technique
At present, along with the day by day increase of automobile demand, car owning amount constantly soaring is so that environmental protection, the problem such as energy-conservation more and more become the focus of social concerns.The structure of the automobile refuelling pipe of prior art mostly is greatly fluorine glue, and this material price is expensive.
Summary of the invention
The purpose of this utility model provides a kind of lower temperature resistance, good springiness, effectively reduces the hyposmosis oil filling pipe of cost.
The technical solution of the utility model is: the hyposmosis oil filling pipe is characterized in that: be comprised of nitrile butadiene rubber skin and PVC＝polyvinyl chloride internal layer, the outer Thickness Ratio with the PVC＝polyvinyl chloride internal layer of described nitrile butadiene rubber is 0.7/0.3.
Advantage and the good effect that the utlity model has are: simple in structure, reliable performance can significantly improve lower temperature resistance, the elasticity of oil filling pipe, effectively reduces cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure:
1, skin 2, internal layer
Embodiment
As shown in Figure 1, the utility model hyposmosis oil filling pipe is comprised of nitrile butadiene rubber outer 1 and PVC＝polyvinyl chloride internal layer 2, and nitrile butadiene rubber outer 1 is 0.7/0.3 with the Thickness Ratio of PVC＝polyvinyl chloride internal layer 2.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
