Just because of above-mentioned many disadvantages, flexible pipe use and transport in very inconvenience, and cost is very high.The present invention in order to address the above problem, adopts new technological scheme just, generates a kind of novel flexible pipe, has overcome above defective.
Summary of the invention
The present invention relates to a kind of high pressure flexible pipe that sprays paint.
High pressure of the present invention inner tube layer, intermediate tube layer and the outer tube layer that flexible pipe comprises that flexible plastic material constitutes that spray paint, wherein intermediate tube layer is conduction PE layer; Two mesospheres between inner tube layer and intermediate tube layer and intermediate tube layer and the outer tube layer are pliable and tough braid, and braid is interwoven by the chemical fibre that plays humidification.The adapted suitable bonding is bonding between inner tube layer and the braid and between braid and the outer tube layer.
The high pressure according to the present invention flexible pipe that sprays paint, the material of wherein said braid are high strength chemistry fiber filaments, and described high strength chemistry fiber filament can be terylene (PET) line, nylon (Nylon) line, aramid fiber (Aramid) line, or the like.
The high pressure according to the present invention flexible pipe that sprays paint, wherein said inner tube layer can include polyethylene (PE) composition; Also can include nylon (Nylon) composition.Described outer tube layer can include polyurethane (PU) composition; Also can include nylon (Nylon) composition.Described intermediate tube layer can include modified polyvinyl chloride (PVC) composition; Also can include polyethylene (PE) composition.
The high pressure according to the present invention flexible pipe that sprays paint, its internal diameter 4.00mm is to the different specification of 12.70mm scope.
In the normal temperature and pressure pipe under the no pressure condition, high pressure of the present invention spray paint flexible pipe can arbitrarily be bent to 180 ° the time minimum bending radius can not surpass 10 times of the own radius of flexible pipe.High pressure of the present invention sprays paint 6.5-8.25 that the scope of flexible pipe minimum bending radius should be flexible pipe self radius doubly.

Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, the high pressure of the present invention flexible pipe 8 that sprays paint is made of inner tube layer 1, intermediate tube layer 3 and outer tube layer 5, and wherein inner tube layer 1, intermediate tube layer 3 and outer tube layer 5 are flexible plastic material.Intermediate tube layer 2 is made of conduction PE layer; Two mesospheres between inner tube layer 1 and intermediate tube layer 3 and intermediate tube layer 3 and the outer tube layer 5 are pliable and tough braid 2 and 4, and braid 2 and 4 is interwoven by the chemical fibre that plays humidification.The adapted suitable bonding is bonding between inner tube layer 1 and the braid 2 and between braid 4 and the outer tube layer 5.
The flexible pipe 8 that sprays paint of high pressure as illustrated in fig. 1 and 2, its braid 2 and 4 material are high strength chemistry fiber filaments, for example terylene (PET) line, nylon (Nylon) line, aramid fiber (Aramid) line, or the like.
In high pressure shown in Fig. 1 and 2 sprayed paint flexible pipe 8, its inner tube layer 1 can include polyethylene (PE) composition, perhaps included nylon (Nylon) composition.Outer tube layer 5 includes polyurethane (PU) composition, perhaps includes nylon (Nylon) composition.Intermediate tube layer 3 includes modified polyvinyl chloride (PVC) composition, perhaps includes polyethylene (PE) composition.
As shown in Figure 3, spray paint high pressure of the present invention more than flexible pipe 8 double flats under the no pressure condition in the normal temperature and pressure pipe or reduce to bend size to the as far as possible little diameter that can not twist together to flexible pipe 8, this moment, the minimum bending radius of flexible pipe 8 then can be above 6.5 times of flexible pipe 8 external diameters.For example minimum bending radius can not surpass 42MM during external diameter of pipe 13.00MM.
The flexible pipe 8 that sprays paint of high pressure as illustrated in fig. 1 and 2, according to the specification difference, its inside diameter ranges is from 4.00mm to 12.70mm.
According to the different size of flexible pipe 8, generally speaking, under the no pressure condition, high pressure of the present invention sprays paint flexible pipe 8 can be arbitrarily crooked in the normal temperature and pressure pipe, and in time when being bent to 180 °, the minimum bending radius 7 of flexible pipe 8 can not surpass 10 times of flexible pipe 8 own radiuses.Preferably, high pressure of the present invention spray paint the scope of flexible pipe 8 minimum bending radius 7 be flexible pipe 8 self radius 6.5-8.25 doubly.
High pressure of the present invention sprays paint the minimum bending radius of flexible pipe 8 greater than 33mm.
Below in conjunction with Fig. 4 the spray paint structure of connection of flexible pipe 8 equipment of high pressure of the present invention is described.High pressure of the present invention spray paint special hose 8 and static paint sprayer (High Pressure Gun) 9 and high-pressure service pump 10 concrete coupling configuration as shown in Figure 4.
The high pressure according to the present invention flexible pipe 8 that sprays paint can bear the unexpected jet pressure of 8500psi.
The high pressure according to the present invention flexible pipe 8 that sprays paint, and under 2200psi paint pressure at least, have the minimum momentum value of at least 5000 pressing periods.
