Abstract
The utility model relates to a three-layer composite fuel hose, which is characterized in that the fuel hose mainly consists of an inner liner layer, a middle adhesion layer and an outer coating layer which are sequentially connected from interior to exterior. The utility model has the advantage that the zero penetration is realized, so the environment is favorably protected; the one-time forming of the inner liner layer, the middle adhesion layer and the outer coating layer is directly completed by new process, the product structure has strong uniformity, the adhesion capability is good, and the quality is reliable; the process is simple, and the working efficiency is enhanced by 30%; the processing procedure is reduced, the production cost is decreased, and the economic benefit is enhanced.
Description
Technical field
The utility model belongs to the gasoline pipe, relates in particular to a kind of three layers of composite fuel flexible pipe.
Background technique
At present, the increase day by day of automobile demand.The fuel hose that now uses is four-layer structure, mainly comprises separation layer, mesoglea, reinforced layer and outer glue-line, all will be through being coated with glue bond between every layer.Its shortcoming is that oil resistance is poor, anti-permeability difference and fuel oil type only are applicable to deficiencies such as unleaded gas.Especially incompatibility bio-fuel-oil, methyl alcohol, APPLICATION OF ETHANOL GASOLINE.Have a kind of six layers of PVF sebific duct osmotic-pressure-tolerant better in the market, but this series product cost is higher, the main engine factory of low and middle-grade cars can't use.In order to satisfy automobile accessories technology and technological requirement, market demands developing a kind of not only environmental protection but also energy-conservation low-penetration fuel flexible pipe urgently.
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of three layers of composite fuel flexible pipe are provided, and through optimization of material combination, has reduced manufacture cost, can satisfy low and middle-grade automobile accessories technology and technological requirement, not only environmental protection but also energy-conservation.
The utility model for achieving the above object, by the following technical solutions: a kind of three layers of composite fuel flexible pipe is characterized in that: mainly constitute integral body by the inside liner, mesoglea and the once-through of outer covering layer co-extrusion that connect successively from inside to outside.
The thickness of described inside liner is 0.5-2mm; The thickness of mesoglea is 0.5-1.2mm; The thickness of outer covering layer is 1-4mm.
Beneficial effect: realize zero infiltration of fuel hose, help environmental protection; Adopt new technology and directly finish inside liner, mesoglea and outer covering layer disposal molding, the product structure conformity is strong, and adhesion is good, reliable in quality; Technology is simple, has improved working efficiency 30%; Reduce manufacturing procedure, reduced cost of production, improved economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
See accompanying drawing for details, a kind of three layers of composite fuel flexible pipe mainly constitute integral body by the inside liner 1, mesoglea 2 and the outer covering layer 3 co-extrusion once-throughs that connect successively from inside to outside.Described inside liner is the Nitrile Rubber material; Described mesoglea is a fluoride material, and outer covering layer adopts chlorosulfonated polyethylene.The thickness of described inside liner is 0.5-2mm; The thickness of mesoglea is 0.5-1.2mm; The thickness of outer covering layer is 1-4mm.Caliber is Φ 4-Φ 55mm, can satisfy the requirement of all size fuel hose.Be widely used in the fuel hose that the vehicle fuel system is flexible coupling and locates, as add oiling, return tube, fuel pipe, vapourizer tube etc.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
