Abstract
The utility model relates to a PPR water supply pipe which comprises an inner-layer copper pipe body and an outer-layer PPR plastic layer, a middle adhesive layer is arranged between the copper pipe body and the PPR plastic layer, and the middle adhesive layer enables the copper pipe body and the PPR plastic layer to be bonded into a whole. The PPR water supply pipe has the advantages that intensity and rigidity of the pipe and dimensional stability and creep resistance of the pipe under high temperature can be improved; construction is facilitated, at present, the PPR water supply pipe is one of ideal sanitary water pipe series products suitable for various occasions and environments, all-copper water contact design is adopted in a whole water supply system, and more than 99% of bacteria in water can die away automatically after entering the copper pipe body.
Description
Technical field
The utility model relates to a kind of PPR supply pipe.
Background technique
Copper pipe has apparent advantage for the conduit pipe of cold water or hot water, and it is harder than plastic tube, and than steel, iron pipe is flexible, has certain high voltage performance and frost heaving resistant performance, can be not aging, more can not meet fire burning, and inner wall smooth, fluid resistance are little.Especially the stable chemical performance of copper, is difficult for being corroded, and can not adhere to grease, carbohydrate and bacterium, germ, and has and the building life-span of the same period.Modern medicine study achievement also points out that copper is human health, one of the indispensable trace element of surviving, and the trace copper dissolving in water has significant sterilization, bacteriostasis and biological function.The application of naked copper pipe also has deficiency: because copper thermal conductivity is up to 383.8W/mK.With naked copper pipe delivering hot water, heat can pass to rapidly in the body of wall or floor of pipeline, make the water temperature of pipe end not reach requirement, building concrete also can, because of being subject to the regular generation stress that expands with heat and contract with cold, cause the tired even be full of cracks of material: naked copper tube outer surface also can produce dewfall simultaneously.Bring damage also easily to surrounding buildings material; Carry cold water easily in pipe, to freeze at low temperatures, and cold and heat succeed each other and bring harmful effect to managing outer concrete building material.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of PPR supply pipe.
The utility model solves the technological scheme that its technical problem adopts: a kind of PPR supply pipe, comprise internal layer copper pipe and outer PPR plastic layer, between copper pipe and PPR plastic layer, be provided with binder mesosphere, binder mesosphere is bonding as a whole by copper pipe and PPR plastic layer.
Further, PPR plastic layer outer surface is coated with steel plate layer.
Further, between copper pipe and PPR plastic layer, be provided with thermal insulation layer.
The beneficial effects of the utility model are: intensity and toughness and the dimensionally stable under high temperature and the creep resistance that can improve tubing; Easy construction, is the current desirable sanitary water tubing product that is applicable to multiple occasion and environment, and the full copper of whole water system touches water design, and in more than 99% water, bacterium is died away after entering copper tube.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. copper pipe, 2.PPR plastic layer, 3. binder mesosphere.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of PPR supply pipe as shown in Figure 1, comprises internal layer copper pipe 1 and outer PPR plastic layer 2, between copper pipe 1 and PPR plastic layer 2, is provided with binder mesosphere 3, and binder mesosphere 3 is bonding as a whole by copper pipe 1 and PPR plastic layer 2.
PPR plastic layer 2 outer surfaces are coated with steel plate layer.
Between copper pipe 1 and PPR plastic layer 2, be provided with thermal insulation layer.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this model utility technological thought, carry out various change and modification completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
