Specific embodiment
With reference to Figure of description, the present invention is described in more detail.
As depicted in figs. 1 and 2, including in spring wear-resistant pipe 1, waterproof layer 2, braiding outer tube 3 and rubber
Pipe 5, spring wear-resistant pipe 1 is sheathed on outside braiding outer tube 3, and the outer surface of braiding outer tube 3 coats
There is waterproof layer 2, inside braiding outer tube 3, be arranged with rubber inner tube 5.Specifically, spring wear-resistant pipe 1
Can be made up of plastics or metal alloy.Spring wear-resistant pipe 1 is sheathed on outside braiding outer tube 3, braiding
Outer tube 3 is sheathed on outside rubber inner tube 5.By spring wear-resistant pipe 1, braiding outer tube 3 and rubber inner tube 5
The sheathed layer by layer formation present invention, be not only simple in structure, the convenient replacing to each part, simultaneously because compiling
The outer surface knitting outer tube 3 is coated with waterproof layer 2, can also be great while so that caliber of the present invention is diminished
Improve wearability and the water proof anti-soil of the present invention, extend the service life of flexible pipe.
In some preferred versions, as shown in figure 3, also including wearing layer 4, wearing layer 4 is fixed on volume
Knit on the inwall of outer tube 3.Furtherly, in a tubular form, braiding outer tube 3 passes through binding agent and glues wearing layer 4
Patch is sheathed on the outside of wearing layer 4, makes wearing layer 4 form an entirety with braiding outer tube 3.By setting
Putting wearing layer 4 can prevent the direct friction of braiding outer tube 3 and rubber inner tube 5 from leading to rubber inner tube 5
Damage, improve rubber inner tube 5 life-span.
In some preferred versions, the length of braiding outer tube 3 can be longer than the length of rubber inner tube 5, compiles
Braiding outer tube 3 after union joint is fixing is in accordion with the two ends of rubber inner tube 5 to knit the two ends of outer tube 3.
Rubber inner tube 5 has elasticity, and the fold that rubber inner tube 5 weaves outer tube 3 after being filled with expansion of liquids disappears.
The Design of length of braiding outer tube 3 is grown up in the length of rubber inner tube 5, rubber inner tube 5 can be facilitated to fill
Enter the stretching of the expansion after liquid, play the effect limiting rubber inner tube 5, prevent rubber inner tube 5 from expanding quick-fried
Split.
Below the manufacture method of the present invention is described in further detail.
As shown in figure 4, the manufacture method of the present invention comprises the steps：
Step 1, prepare spring wear-resistant pipe 1, hard plastic bar is made helical form, form spring wear-resistant pipe
1；Furtherly, spring wear-resistant pipe 1 is prepared by hard plastic bar, and is extruded into spring by extruder
Spiral coil, hard plastic bar is PVC, PU and TPE material.
Step 2, preparation braiding outer tube 3, chemical fiber is made braiding outer tube 3 by braiding；Further
Say, this weaving passes through warp 1 and 2, parallel passes through to intersect on braider and is woven into cylinder up and down
Shape.
Step 3, coating waterproof layer 2, immerse in liquid waterproofing agent by after braiding outer tube 3 heat drying,
Subsequently take out braiding outer tube 3 and put into drying waterproofing agent in baking oven, form waterproof layer 2；In some enforcements
In example, braiding outer tube 3 is put into 5 minutes in baking oven, when braiding outer tube 3 surface reaches 80 DEG C, will
It takes out from baking oven and immerses in liquid TPU waterproofing agent, makes the surface-coated one of braiding outer tube 3
The waterproof layer 2 that layer liquid TPU waterproofing agent is formed, then the braiding outer tube 3 with TPU waterproofing agent is put
Enter and dry 20 minutes so as to the outer surface of braiding outer tube 3 adheres to soft waterproof layer 2 in 80 DEG C of baking oven,
Play waterproof and antifouling effect.
Step 4, prepare wearing layer 4, soft highstrenghtpiston is made the wearing layer 4 of tubulose；Further
Say, soft highstrenghtpiston can be PVC, PU and TPE material, wearing layer 4 passes through water cooling shape
Become.
Step 5, bonding braiding outer tube 3 and wearing layer 4, wearing layer 4 is bonded in braiding by binding agent
On the inwall of outer tube 3；Furtherly, wearing layer 4 passes through polyurethane sticking under high-temperature and high-pressure conditions
Agent is bonded on the inwall of braiding outer tube 3, and temperature is about 80 DEG C～100 DEG C, and pressure is about
0.1MPa～0.2MPa.Temperature be 80 DEG C, pressure be 0.1MPa when, braiding outer tube 3 with wear-resisting
Layer 4 can preferably be mutually bonded and also allow for mutually peeling off simultaneously；It is 90 DEG C in temperature, pressure is
During 0.15MPa, braiding outer tube 3 can reach best adhering state with wearing layer 4；In temperature
For 100 DEG C, when pressure is 0.2MPa, braiding outer tube 3 can be firmly bonding with wearing layer 4,
It is difficult mutually to peel off.
Step 6, prepare rubber inner tube 5, first rubber raw materials are made the internal tubular body in hollow, then
Again tubular body is put into heating sulfuration in baking oven, sulfuration makes gum elastic inner tube 5 after terminating；Further
Say, tubular body is put into heating-up temperature in baking oven and is about 120 DEG C～140 DEG C, the time of sulfuration is about
1 hour～1.5 hours.When heating-up temperature is 120 DEG C, cure time is 1 hour, the rubber being formed
Inner tube 5 elasticity is less, is adapted in use in the less environment of fluid pressure；When heating-up temperature is 130 DEG C,
Cure time is 1.25 hours, and rubber inner tube 5 elasticity being formed is moderate, is adapted in use to transmitting big portion
Divide in the environment of liquid；When heating-up temperature is 140 DEG C, cure time is 1.5 hours, is adapted in use in liquid
The larger occasion of body pressure.Producer can be according to the difference of product use environment, and it is suitable flexibly to select
Heating-up temperature and cure time, thus produce different products.
Step 7, group shock mount wear-resistant pipe 1, braiding outer tube 3 and rubber inner tube 5, first by rubber inner tube 5
Penetrate in braiding outer tube 3 and fixing, then braiding outer tube 3 is penetrated in spring wear-resistant pipe 1 and fixing.Make
For a kind of preferred version, rubber inner tube 5 is fixed by being provided with externally threaded union joint with braiding outer tube 3,
Braiding outer tube 3 is fixed by setting female union joint with spring wear-resistant pipe 1.Threadedly connect
Connect each part, be conducive to the maintenance when one of parts damages and replacing.
The above is only the optimal way of the present invention it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, some similar deformation can also be made and change
Enter, these also should be regarded as within protection scope of the present invention.
