Abstract
The utility model discloses an air -fuel mixture that stainless steel connects oil pipe assembly for fuel, include hose, coupling, withhold the sleeve, the hose both ends are connected with the coupling through withholding the sleeve, the cooperation sets up the nut on the joint, and correspond the position at the internal surface of the surface that connects and nut and punish and do not be provided with semi -circular ring channel, it is provided with the steel wire to peg graft in the ring channel. The utility model discloses carbon steel that will be ordinary connects the improvement and is full stainless steel, can improve the life of joint greatly, avoids the corrosion damage under the long -term adverse circumstances. The nut connects the method that adopts the steel wire with the flared type and carries out fixed connection, and it is convenient to assemble, rotates in the same direction as smooth convenient to use. The sleeve sawtooth can directly impale sheath and outer glue film, and direct action fixes in the process wire enhancement layer, need not to skin, and both convenient processing has utilized outer glue film to fill the clearance of sleeve inslot again, has improved the sealing performance after cooperating intensity and withholding.
Description
Technical field
The utility model belongs to pipe transportation technology field, is specifically related to a kind of gas and oil mixed fuel oil pipe assembly of stainless joint.
Background technique
At automotive field, fuel oil is carried mainly through metal oil conduit between fuel injection system and oil pump, utilize metal oil conduit to carry fuel oil to be mainly to adapt to it severe and bear the working environment of high pressure, there are easily vibrations in traditional metal oil conduit, the defect such as fragile, simultaneously because quality is hard, the problem such as not flexible, cause inconvenience is installed, for solving this technical problem, with flexible pipe alternative metals oil pipe, then by link, flexible pipe is connected with pipe joint, the oil pipe assembly of this kind of vibrational power flow, adopt nut and flared fitting snap-fit engagement, this kind of Placement frictional force is large, concentricity is general, after assembling, sealing effect is not good enough, in link, skewed sawtooth is set usually, when hydraulic fitting is connected with hose buckling, generally all need to carry out peeling processing, being convenient to the inclined teeth groove that link inwall is arranged press-in steel wire of internal layer to be fixed connection, there is the problem of assembling inconvenience in this oil pipe assembly equally.
Model utility content
For problems of the prior art, the purpose of this utility model is the gas and oil mixed fuel oil pipe assembly providing a kind of stainless joint.
The gas and oil mixed fuel oil pipe assembly of described stainless joint, it is characterized in that this gas and oil mixed fuel oil pipe assembly comprises flexible pipe, joint, withholds sleeve, described flexible pipe two ends are connected with joint by withholding sleeve, described joint is equipped with nut, be respectively arranged with semicircle circular groove at the outer surface of joint and the internal surface corresponding position of nut, in described circular groove, grafting is provided with steel wire.
The gas and oil mixed fuel oil pipe assembly of described stainless joint, is characterized in that described flexible pipe comprises inner glue layer, steel wire reinforcement layer, outer glue-line composition.
The gas and oil mixed fuel oil pipe assembly of described stainless joint, uniformly on the inwall that it is characterized in that withholding sleeve is provided with sawtooth, and described serrated vertical pipe sleeve lining is arranged.
The gas and oil mixed fuel oil pipe assembly of described stainless joint, is characterized in that uniformly on described outer glue-line being provided with acanthopore.
Common carbon steel joint is improved to all steel material by the utility model, greatly can improve the working life of joint, avoid the corrosion and damage under long-term rugged environment.Nut and flared fitting adopt the method for wearing steel wire to be fixed to be connected, and it is convenient to assemble, and rotates smooth, easy to use.Sleeve sawtooth directly can pierce through sheath and outer glue-line, directly acts on process wire enhancement layer and is fixed, and without the need to carrying out peeling, both convenient processing, make use of again the gap in outer glue-line filling sleeve groove, improve and coordinate intensity and the sealability after withholding.

Fig. 3 is the cross-sectional view after sleeve assembling;
In figure: 1-flexible pipe, 2-joint, 3-sleeve, 4-nut, 5-steel wire, 6-inner glue layer, 7-steel wire reinforcement layer, 8-sawtooth.
Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
As Figure 1-3, the gas and oil mixed fuel oil pipe assembly of the utility model stainless joint, comprise flexible pipe 1, pipe joint 2, withhold sleeve 3, flexible pipe 1 is made up of inner glue layer 6, steel wire reinforcement layer 7, outer glue-line 8, wherein, inner glue layer 6 adopts the material of resistance to liquefied petroleum gas (LPG), the material that outer glue-line 8 adopts resistance to weather excellent, flexible pipe 1 outer braid Stainless Steel Wire sheath.Flexible pipe 1 two ends are connected with joint 2 by withholding sleeve 3, joint 2 is equipped with nut 4, semicircle circular groove is respectively arranged with at the outer surface of joint 2 and the internal surface corresponding position of nut 4, in circular groove, grafting is provided with steel wire 5, and just circular circular groove internal diameter matches the external diameter of iron wire 5 with two halves.Wherein, uniformly on the inwall withholding sleeve 3 be provided with sawtooth 9, and serrated vertical pipe sleeve lining is arranged.
The utility model joint adopts Stainless Steel Wire material, greatly can heighten the working life of joint, avoid the corrosion and damage under long-term rugged environment, nut and flared fitting adopt the method for wearing steel wire to be fixed to be connected, it is convenient to assemble, and rotates smooth, easy to use; The sawtooth arranged in sleeve directly can pierce through outer glue-line and act on process wire enhancement layer, without the need to carrying out peeling, both easy to process, make use of again outer glue-line and is filled with gap in sleeve groove, improve and coordinate intensity and the sealability after withholding.The mesosphere of braided steel wire not only has raising intensity, ensures the effect of Security, can also eliminate the accumulation of static electricity in the operation of conveying oil gas, meet security against fire.This oil pipe assembly can use within the scope of-40 ~ 120 DEG C, and maximum service pressure is 5MPa, has structure reliable, steady quality.Due to the molecular structure property of rubber material, under the environment of long-term high pressure conveying combination gas medium, combustion gas can be seeped into process wire layer from inner glue layer, and gather in the gap in mesosphere, run up to a certain degree, outer glue-line bubbling can be caused even to break, and Some gases medium is leaked by pipe joint crimping end, cause oil pipe mass defect, even cause security incident.The even acanthopore of outer film surface, can discharge gas infiltration, the flexible pipe bubbling avoiding accumulated gases to cause, destruction in time.
