Abstract

The utility model relates to a cold and hot water pipe of green type PP -R guarantees the body, the body is by outward to interior outer jacket, metal level, the inlayer of including in proper order, the coating has the antibiotic oxygen layer that hinders on the inner wall of inlayer, be equipped with the heat preservation between outer jacket and the metal level, the heat preservation is made for expanded material, outer jacket, heat preservation, metal level, inlayer combine to become an organic whole through crowding altogether, the utility model discloses an antibiotic oxygen layer that hinders of coating can have the suppression or the effect of exterminateing to the various bacteriums of aquatic on the inner wall of body inlayer, can prevent effectively that pipe inner wall from breeding the bacterium, simultaneously, because the antibiotic oxygen layer that hinders of nanometer titanium dioxide has better stability, has fine mould proof function to can keep the sanitation and hygiene of quality of water, can not produce the influence that is unfavorable for health and sanitation is green type building materials, be equipped with the heat preservation between outer jacket and metal level, effectively reduced calorific loss.

Description

A kind of environmental type PP-R hot water pipe

Technical field

This utility model belongs to cold hot water piping technical field, is specifically related to a kind of environmental type PP-R hot water pipe。

Background technology

PP-R to cry not only three type polypropylene tube and but also be polypropylene random copolymer pipe or PPR pipe, there is energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and maintenance simplicity, the advantages such as long service life, it is widely used in building water supply and drainage, town and country plumbing, gas, electric power and cable jacket, industrial fluids is carried, the building industries such as agricultural irrigation, municipal administration, industry and agriculture field, it it is the new green environment protection type chemical building material greatly developed in the world and apply at present, it is the desirable tubing of conveying hot and cold water, its integrated performance index is better than galvanized pipe and other tubing, it is the leading products of European and American developed countries' feedwater piping。

PP-R hot water pipe is to adopt maximum a kind of water supply lines in current house ornamentation engineering, the PP-R hot water pipe used in prior art is owing to carrying hot and cold water for a long time, in pipeline, oxygen permeates breed bacteria strong, easy, cause pipeline premature aging, it is easily subject to corrosion and damages, decrease the service life of pipeline, use for a long time along with pipeline during for hot-water heating system and heat energy loss occurs。

Utility model content

In order to solve the problems referred to above that prior art exists, this utility model provides a kind of environmental type PP-R hot water pipe。

The technical scheme that this utility model adopts is: a kind of environmental type PP-R hot water pipe, assure body, described body includes outer jacket, metal level, internal layer from outside to inside successively, the inwall of described internal layer is coated with antibacterial oxygen-resistance layer, it is provided with heat-insulation layer between described outer jacket and metal level, described heat-insulation layer is that expanded material is made, and described outer jacket, heat-insulation layer, metal level, internal layer are combined into one by co-extrusion。

Further, described antibacterial oxygen-resistance layer adopts nano titanium oxide to make。

Further, the thickness of described antibacterial oxygen-resistance layer is 0.1mm～0.2mm。

Further, described metal level is not less than 10.5% for inscription content, and carbon content is not more than the rustless steel of 1.2%, the copper of surface treatment or copper alloy。

Further, the joint of described body is connected by sweat soldering。

Further, the joint of described body is connected by electric smelting。

The beneficial effects of the utility model are: by being coated with antibacterial oxygen-resistance layer on the inwall of body internal layer, the various antibacterials in water can have suppression or killing action, can effectively prevent inboard wall of tube body breed bacteria；Simultaneously as nanometer titanium dioxide antibiotic oxidation prevention layer has good stability, there is good antimildew function such that it is able to keep the sanitation and hygiene of water quality, will not produce to be unfavorable for health and sanitary impact, be a kind of environmental type building materials；Between outer jacket and metal level, it is provided with heat-insulation layer, effectively reduces thermal loss；PP-R pipeline is completely fused together through its junction molecule of hot-melt adhesive paste and molecule, without obvious interface, therefore whole tubing even one, solves water supply system and leaks safe problem, and easy for installation, joint is reliable。

Detailed description of the invention

As shown in Figure 1, this utility model provides a kind of environmental type PP-R hot water pipe, assure body 1, described body 1 includes outer jacket 2, metal level 3, internal layer 4 from outside to inside successively, being coated with the antibacterial oxygen-resistance layer 5 that nano titanium oxide is made on the inwall of internal layer 4, the thickness of antibacterial oxygen-resistance layer is 0.1mm～0.2mm；Being provided with heat-insulation layer 6 between outer jacket 2 and metal level 3, heat-insulation layer 6 is made for expanded material, can effectively reduce thermal loss during transmission hot water, and outer jacket 2, heat-insulation layer 6, metal level 3, internal layer 4 are combined into one by co-extrusion。

Metal level 3 is not less than 10.5% for inscription content, and carbon content is not more than the rustless steel of 1.2%, the copper of surface treatment or copper alloy, it is to avoid pipeline in use causes degraded or aging。

The joint of body 1 adopts hot melt and electric smelting to connect, and easy for installation, joint is reliable, and the intensity of its connecting portion is more than the intensity of tubing itself, and solution water supply system is leaked safe problem。

This utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but in its shape or structure, do any change; every have same or like with the application like technical scheme, all fall within protection domain of the present utility model。
