Abstract
The utility model discloses the PPR pipe that a kind of high temperature resistant is not easy deformation, by adding high temperature resistance layer among PPR pipe part inner and outer wall so that PPR pipe will not be bent in high temperature, play humidification, remove the potential safety hazard in construction, use.
Description
Technical field
PPR pipe field is the utility model is related to, more particularly to a kind of high temperature resistant is not easy the PPR pipe of deformation.
Background technology
PPR is the abbreviation of 3 third polyethylene, is called polypropylene random copolymer pipe, by the way of thermal welding, is had special
Welding and cutting tool, there is higher plasticity.Price also very economical.Additional heat-insulation layer, heat-insulating property is more preferable, tube wall also very light
It is sliding, do not include the joint of inside and outside silk.Embedded wall is generally used for, or in deep-well built-in pipe.Pipe-line system is safe and reliable, not
Infiltration, service life was up to 50 years.But construction technical requirement is high, specific purpose tool and professional person need to be used to be constructed, can
Ensure system safety.
Inherently a kind of High molecular polymer of PPR materials, and it is current with the tubing of PPR material manufactures to be entirely capable of pressure-bearing
The tap water pressure of national standard.The cost of PPR materials is also more much lower than stainless steel material, and the technique manufactured uses mould skill
Art, it is more suitable for producing in enormous quantities.
However, according to statistics, if it is for domestic hot-water, PPR pipe is resistant to temperature as 70 degree for a long time.Short time can be with resistance to
By 90 degree of temperature.
Heating is if it is for, PPR pipe highest operating temperature is 80 degree.The maximum temperature that short time can be resistant to is
90 degree.
As can be seen here, existing PPR pipe part only has a body, in actual use such as high temperature, can soften, make engineering
In potential safety hazard be present, be also not suitable for high-temperature operation.
Utility model content
In view of this, the utility model provides the PPR pipe that a kind of high temperature resistant is not easy deformation, by giving PPR pipe part inwall
With high temperature resistance layer is added among outer wall so that PPR pipe will not be bent in high temperature, play humidification, removed construction, used
In potential safety hazard.
Technical scheme is used by the utility model：A kind of high temperature resistant is not easy the PPR pipe of deformation, and the PPR pipe includes
Outer wall, inwall and hollow structure, one layer of high temperature resistance layer is added among the outer wall and inwall.
Further, the high temperature resistance layer is glass fibre.
Further, high-temperature-resistant layer is scribbled on the inwall.
Further, the high-temperature-resistant layer thickness is 1-5 millimeters.
The outer wall and the high temperature resistance compound PPR of layer central filler, the outer wall and high temperature resistance layer by PUR it is Nian Jie and
Into；The inwall and the high temperature resistance compound PPR of layer central filler, the inwall form with high temperature resistance layer by the way that PUR is Nian Jie.
The beneficial effects of the utility model are：The utility model among PPR pipe part inner and outer wall by adding anti-height
Warm layer so that PPR pipe will not be bent in high temperature, play humidification, remove the potential safety hazard in construction, use.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
Wherein, 1, outer wall；2nd, inwall；3rd, high temperature resistance layer；4th, hollow structure.
Embodiment
The utility model is described in detail below with reference to accompanying drawing, as shown in figure 1, one kind provided by the utility model
High temperature resistant is not easy the PPR pipe of deformation, and the PPR pipe includes outer wall 1, inwall 2 and hollow structure 3, among the outer wall and inwall
Add one layer of high temperature resistance layer 4.
As the another improvement of the technical solution of the utility model, the high temperature resistance layer 4 is glass fibre.
The PPR pipe part for having added high temperature resistance layer possesses following major feature:
1st, linear expansion coefficient is only 20~30% or so of common PPR products；Thoroughly solve the flexible of plastic conduit
Problem.
2nd, tubing rigidity reinforced, pipeline sagging is prevented, while also reduces the density and quantity of the fixed strong point, from
And reduce the comprehensive cost of engineering.
3rd, stress levels are higher, and in the case where being commonly designed power of trembling, service life is longer.
4th, resistance to elevated temperatures more preferably, energy-saving consumption-reducing positive effect；FR/PPR is applied in hot-water heating system, normal use temperature
Up to 95~100 DEG C, the temperature using medium was both improved, the thickness of insulation material can be reduced again, its integrated cost is lower.
5th, water-carrying capacity is big:Under the other pressure condition of ad eundem, the wall thickness book of FR/PPR tubing, the interior of tubing is added
Footpath, so as to improve water-carrying capacity (increase by 20%).
6th, solves the oxygen flow sex chromosome mosaicism of pipeline, the interior table health directly contacted with water is nontoxic, good airproof performance, will not be formed
Sphagna.The composition in fiberglass reinforced FR/PP-R tubing intermediate layer, completely cut off extraneous air completely and do not penetrate into pipeline, so as to suppress algae
Class grows, and keeps water quality fresh pure
As the another improvement of the technical solution of the utility model, high-temperature-resistant layer is scribbled on the inwall 2.
As the another improvement of the technical solution of the utility model, the high-temperature-resistant layer thickness is 1-5 millimeters.
Specifically, high-temperaure coating therein is a kind of slurry of bone white, have energy-efficient, thin layer thermal insulation,
Fire retardant anticorrosion, integral new type reflection heat insulating coatings are electrically isolated from, coating can be formed in body surface and connected by closing microballon
Three-dimensional network hollow-core construction together, effectively prevent heat conduction and heat exchange.
In addition, the thickness of the high-temperaure coating between 1mm-5mm, uniformly applies the internal layer for being bonded at whole PPR inwalls；Institute
The high-temperaure coating of viscous respective thickness will be applied with the PPR surfaces of inner bag high temperature hot water contacts by having.The thickness of heat-insulation layer according to
Required heat-insulating property is configured.
As the another improvement of the technical solution of the utility model, the outer wall and the high temperature resistance compound PPR of layer central filler,
The outer wall forms with high temperature resistance layer by the way that PUR is Nian Jie；The inwall and the compound PPR of high temperature resistance layer central filler, it is described interior
Wall forms with high temperature resistance layer by the way that PUR is Nian Jie.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
