Material.
PE-RT pipe has good flexibility, it is made to facilitate economy when being laid with, and the tubing of production can lead in construction
The usage amount the methods of coiled and be bent and reduce pipe fitting is crossed, construction cost is reduced.Because the flexibility of PE-RT pipe is better than other pipes
Material, so PE-RT pipe is when in use, the case where being easy to appear compressive deformation, PE-RT manages deformed water flux and can reduce, and is
This is it is proposed that a kind of pressure resistance PE-RT tubing.
Utility model content
Purpose of the utility model is to solve PE-RT tubing exists in the prior art vulnerable to pressure, its water flux is influenced
The shortcomings that, and a kind of pressure resistance PE-RT tubing proposed.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of pressure resistance PE-RT tubing is designed, including main core pipe, Withstand voltage layer and wearing layer, the Withstand voltage layer are set to main core
Pipe is outer, and the Withstand voltage layer includes stiffener rings, filler, and the quantity of the stiffener rings is multiple, and the fixation of multiple reinforcing central spacers is set
It is placed on main core pipe, filler is equipped between the stiffener rings, the wearing layer is set to outside Withstand voltage layer, the wearing layer and pressure resistance
Mesh grid is equipped between layer, the wearing layer is coated with oversheath.
Preferably, the main core pipe is made of inner and outer tubes, and outer tube is set to other than inner tube, said inner tube and outer tube
It is formed by ethylene and octene copolymer, the density of the outer tube is less than the density of inner tube.
Preferably, said inner tube inner-wall spraying has a nanometer silver coating.
Preferably, the stiffener rings are made of ABS resin, and the filler uses polystyrene foam particles.
Preferably, the mesh grid is woven using nylon fiber.
Preferably, the wearing layer is sprayed using PTFE.
Preferably, the oversheath is externally provided with anti-skidding twill.
The utility model proposes a kind of pressure resistance PE-RT tubing, beneficial effect is: the PE-RT tubing increases pressure resistance
Layer and wearing layer increase the voltage endurance capability of main core pipe by stiffener rings and filler, and stiffener rings are using high-intensitive ABS material system
At, and ABS material is installed on the outside of main core pipe, is increased the voltage endurance capability of main core pipe by spaced multiple stiffener rings, is kept away
Exempt from main core pipe compressive deformation, while increase has filler between stiffener rings, and the bending ability of main core pipe is avoided to be affected, and should
Tubing increases wearing layer, while PTFE coating increases the service life of tubing.
