Description
Technical field
The utility model relates to a kind of novel high-pressure flexible pipe that sprays paint, especially as the spray paint special high-pressure pipe of machine of high pressure.
Background technique
At present, there are a lot of producers also to produce similar flexible pipe both at home and abroad, basically based on braided steel wire.It is overweight that but the braided steel wire flexible pipe has, the hardness height, and the price height such as is inconvenient to manipulate at shortcoming.
In addition, braided steel wire flexible pipe inner tube product, mesosphere, outer tube are bonding bonding insecure, and easy layering when crooked, during pressurized, cracking are corroded when running into acid-base material, leakage and explosion easily.
Simultaneously, owing to use the braided steel wire flexible pipe, the hardness height, minimum bending radius is too big; Bring many inconvenience in transportation with in using.
Just because of above-mentioned many disadvantages, flexible pipe use and transport in very inconvenience, and cost is very high.The utility model 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 utility model relates to a kind of high pressure flexible pipe that sprays paint.
High pressure of the present utility model 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.
According to the high pressure of the present utility model flexible pipe that sprays paint, the material of wherein said braid is a high strength chemistry fiber filament, and described high strength chemistry fiber filament can be terylene (PET) line, nylon (Nylon) line, aramid fiber (Aramid) line, or the like.
According to the high pressure of the present utility model 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.
According to the high pressure of the present utility model 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 utility model 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 utility model sprays paint 6.5-8.25 that the scope of flexible pipe minimum bending radius should be flexible pipe self radius doubly.
Flexible pipe heat extrusion compacting outer tube on the pipe fitting of fibre threads braiding because high pressure of the present utility model sprays paint, guaranteed no gap hot joining between inner tube layer, intermediate tube layer and the outer tube layer, this flexible pipe does not have layering, cracking under bending, pressure-bearing condition, accomplished that three layers of one have light weight, intensity height, resistance to pressure are good, bending radius is little, advantages such as pliability is good, in light weight, moderate cost.
