Abstract

The utility model provides a new fuel flexible pipe, comprising a rubber inner pipe which is externally provided with a nylon wire braid, and a polyurethane bonding layer for combining the rubber inner pipe and the nylon wire braid is arranged between the rubber inner pipe and the nylon wire braid. The new fuel flexible pipe weighs 40% less than the products used in current markets, which has an excellent pressure resistance property because of the employment of the nylon wire braid. Only a pair of shears is needed to cut off the pipe, and the section of the flexible pipe has no scattering phenomenon of nylon wire braid after the pipe is cut off, thereby providing convenience to assemble detachable joints.

Description

The novel fuel flexible pipe

Technical field

The utility model relates to fuel hose.

Background technique

Carry the flexible pipe of fuel oil (comprising diesel oil), lubricant oil and antifreeze liquid need have excellent oil resistant, anti-permeability in the racing car, and owing to this pipeline often needs to link to each other with removable joint, therefore after requiring body to cut off, the flexible pipe section does not allow to occur the problem of spending of loosing.

The product of Shi Yonging is the rubber hose that strengthens with galvanized wire in the market, in use will use special-purpose Pipe Cutting and joint to withhold instrument, and operability is not strong, and the body poor in flexibility, and body weight is big, and is not portable.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of body pliability good, be not easy to occur the loose novel fuel flexible pipe of flower of section after cutting off, for this reason, the utility model is by the following technical solutions: it comprises pipe in the rubber, the outer nylon thread braiding jacket layer that is surrounded by of pipe is provided with the bonding layer of the polyurethane that they are bonded together in the described rubber between pipe and the nylon thread braiding jacket layer in the described rubber.

By above technological scheme, the utility model light weight (product that uses than market is light by 40%), body good pressure-resistant performance (using the knit nylon jacket layer), body does not need special tool(s) when cutting off, only need one scissors got final product, and after the body cut-out, the diffusing flower of nylon thread braiding jacket layer phenomenon does not appear in the flexible pipe section, more helps the assembling of removable joint.

Description of drawings

Fig. 1 is embodiment's that the utility model provides structural representation.

Embodiment

With reference to accompanying drawing.This figure is with the structural representation after embodiment that the utility model the provides strip off layer by layer, as shown in the figure, the utility model comprises pipe 1 in the rubber, the pipe 1 outer nylon thread braiding jacket layer 3 that is surrounded by is provided with the bonding layer 2 of the polyurethane that they are bonded together in the rubber between pipe and the nylon thread braiding jacket layer 3 in the described rubber.

Pipe 1 selects fuel resistance to make by excellent synthetic rubber in the rubber, be used for carrying respective media, the nylon thread of nylon thread braiding jacket layer 3 is to adopt the nylon recombination line, being about to the long monofilament of nylon that some diameters are about 1.5 microns slightly twists and is combined into a thick long line, behind the Stranding machine plying, carry out the product braiding again, be characterized in the intensity height, can replace steel wire.The effect of nylon thread braiding jacket layer 3 is pipes in the protection rubber, and pipe in the rubber is carried out reinforcement, and the assurance flexible pipe is used safely under higher working pressure, and the ageing-resistant performance of nylon thread is better than rubber in addition; The bonding layer of polyurethane 2 is bonded together pipe 1 and nylon thread braiding jacket layer 3 in the rubber, guarantees not occur after body cuts off the section nylon thread braiding jacket layer flower that looses.The bonding layer of this polyurethane good springiness, the adhesion strength height can guarantee that body the woven sleeve pull-up do not occur and falls under the large deformation situation.

Manufacture process of the present utility model is as follows:

The first step, use cold feed extruder pipe 1 in the rubber to be coated on the plug by technological requirement, simultaneously on body, evenly coat isolating agent, prevent that body from bonding together mutually, sends the semi-finished product dish of extruding into sulfurizing pot and carry out semi-cure on the aluminium dish when sulfuration;

Second step, will be in the rubber pipe 1 by polyurethane binder applicator (the bonding layer 2 of polyurethane), on one side coating adhesive weave on one side, the coverage scale that nylon thread is woven on the body is 95%, forms nylon thread braiding jacket layer 3;

The 3rd step allowed polyurethane binder solidify 4 hours under the 50 degree temperature, made interior pipe 1 of rubber and nylon thread braiding jacket layer 3 bonding as a whole.

The product of producing according to said structure and step has light weight (product that uses than market is light by 40%), the advantage of body good pressure-resistant performance (using the high-strength nylon braid), body does not need special tool(s) when cutting off, only need one scissors got final product, and after the body cut-out, the diffusing flower of nylon thread braiding jacket layer phenomenon does not appear in the flexible pipe section, more helps the assembling of removable joint.

Claims

1, novel fuel flexible pipe is characterized in that it comprises pipe in the rubber, and the outer nylon thread braiding jacket layer that is surrounded by of pipe is provided with the bonding layer of the polyurethane that they are bonded together in the described rubber between pipe and the nylon thread braiding jacket layer in the described rubber.
