Abstract
The utility model relates to a fuel feeding hose component, which solves a problem that sealing performance of the utility model is easy to be ineffective under the high-temperature, high-pressure, and vibrating operating state, and accordingly, the utility model has the advantages of higher sealing performance and holding capacity of the higher sealing performance. The utility model comprises a rubber pipe and metal pipe joints, wherein the metal pipe joints are arranged on both end portions of the rubber pipe. The utility model is characterized in that the external surfaces of contact portions of the internal walls of the metal pipe joints (1) and the rubber pipe (2) are provided with coatings.
Description
Technical field
The utility model relates to a kind of fuel oil oil inlet hose assembly.
Technical background
Automobile is made up of high pressure hose and the metallic pipe coupling that is arranged at its two ends with high pressure fuel oil inlet hose assembly, and metallic pipe coupling is crimped on one in the high pressure hose assembling; The high pressure fuel flexible pipe requires to be applicable under-40 ℃～125 ℃ the operating temperature, and the generation of fuel oil medium seepage phenomenon must not be arranged.In the prior art, the metallic pipe coupling outer surface that directly contacts with the sebific duct inwall is directly assembled with high-pressure rubber pipe after cutting, or bulk heat treatment is assembled with high-pressure rubber pipe again; These high pressure fuel flexible pipes can reach its job requirement substantially, but it is under the working state of high temperature, oil resistant, high pressure, car load vibration, after using a period of time, the connecting part of high-pressure rubber pipe inwall and the metallic pipe coupling outer surface that is in direct contact with it usually has the seepage phenomenon to take place, and causes its sealing to lose efficacy.
As mentioned above, the defective of prior art is: the sealing of high pressure fuel oil inlet hose assembly lost efficacy under the working state of high temperature, high pressure and vibration easily.
Summary of the invention
The problem that the sealing of the high pressure fuel oil inlet hose assembly that prior art exists of having solved the utility model lost efficacy under the working state of high temperature, high pressure and vibration easily provides a kind of high pressure fuel oil inlet hose assembly.A kind of fuel oil oil inlet hose assembly, the outer surface of metallic pipe coupling and sebific duct inwall contact segment is provided with coating, and coating thickness is even, and thickness is 0.02～0.06mm; Metallic pipe coupling and high-pressure rubber pipe assembling are crimped on one, coating the high-pressure rubber pipe inwall and with metallic pipe coupling outer surface that the high-pressure rubber pipe inwall directly contacts between as the transition connecting part, because high temperature resistant, the anti-vibration of coating, the elasticity that it is certain also has high adhesive ability, the sealing of the connecting part of the metallic pipe coupling outer surface that can strengthen the high-pressure rubber pipe inwall significantly and be in direct contact with it and the hold facility of sealing also just make the sealing of high pressure fuel oil inlet hose assembly and the hold facility of sealing be improved.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of fuel oil oil inlet hose assembly, comprise sebific duct, metallic pipe coupling, metallic pipe coupling is arranged at the sebific duct two end part, it is characterized in that the outer surface of described metallic pipe coupling and sebific duct inwall contact segment is provided with coating.Coating the high-pressure rubber pipe inwall and with metallic pipe coupling outer surface that the high-pressure rubber pipe inwall directly contacts between as the transition connecting part; That coating possesses is high temperature resistant, oil resistant, characteristic such as high pressure resistant, and because the elasticity of himself, prevents that the connecting part from producing the seepage slit with the adhesive ability that improves the connecting part, the anti-vibration ability of strengthening whole assembly.
As preferably, described coating thickness is even, and thickness is 0.02～0.06mm.Each service factor such as comprehensive thermal shrinkage, join strength, as preferable selection, coating thickness is arranged on 0.02～0.06mm.
As preferably, be provided with the enhancing construction layer that comprises aramid fiber enhancing silk in the described sebific duct 3.Strengthen the intensity of sebific duct, unlikely because be heated, stressedly cause that the sebific duct distortion is excessively and cause the seepage phenomenon to produce.
Therefore, the utlity model has higher sealing and higher characteristics such as sealing hold facility.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Among the figure: 1. metallic pipe coupling; 2. sebific duct;
Specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of fuel oil oil inlet hose assembly includes metallic pipe coupling 1 and sebific duct 2.Metallic pipe coupling is located at the sebific duct two end part; Be provided with in the sebific duct 2 and comprise that aramid fiber strengthens the enhancing construction layer of silk; Metallic pipe coupling and high-pressure rubber pipe assembling are crimped on one.
Metallic pipe coupling 1 is provided with coating with the outer surface of sebific duct 2 inwall contact segments, and coating thickness is even, and thickness is 0.02～0.06mm; Coating the high-pressure rubber pipe inwall and with metallic pipe coupling outer surface that the high-pressure rubber pipe inwall directly contacts between as the transition connecting part.
Claims (3)
