Abstract
The utility model relates to a water supply pipe, in particular to a composite water supply pipe. The composite water supply pipe is characterized by consisting of a PP-R (polypropylene) inner layer with natural color and a PP-R outer layer added with light-resistant colorant, wherein the PP-R inner layer and the PP-R outer layer are co-extruded together. The composite water supply pipe adopting the technical scheme is low in cost, large in flexibility, easy to connect, free of pollution to water quality and easy to process.
Description
Technical field
The utility model relates to a kind of pipe material for water supply, is specifically related to a kind of compound water pipe.
Background technique
At present, the water-feeding pipes that hot and cold water is used comprises metal tube, plastic tube and composite metal-plastic pipe, metal tube exist such as, be prone to corrosion, easy blocking and broken bad; Intensity is big, and is flexible poor, must adopt joint to turn; This socket is very easy to come off, and causes leaking.And plastic water supply pipe is seen the light easy ageing, and is usually female in order to improve the look that need add lucifuge working life, and the female easy separation of the lucifuge look in the water pipe comes out to get in the water, the quality of potable water impacted, and finally damage health; Composite metal-plastic pipe has adopted metal shell, though it has solved the problem of corrosion, this water pipe still exists flexible poor, and the problem that processing cost is high is difficult for promoting the use of on a large scale.
The model utility content
The technical problem that the utility model will solve provide a kind of cost low, flexible big, be prone to connect, the not polluted water and the water pipe of processing easily.
In order to solve the problems of the technologies described above, the utility model provides a kind of compound water pipe, it is characterized in that: the PP-R skin with adding the lucifuge look female by co-extrusion true qualities PP-R internal layer together constitutes.
Pipe material by adopting double-layer coextrusion mode, the internal layer water white transparency, outer owing to added lucifuge look mother for dark, the lucifuge look female is for having plastics a kind of additive commonly used now.
The total thickness of above-mentioned requirements satisfies the regulation of NBS to the PP-R tube wall thickness.
Adopt the compound water pipe of technique scheme to have following advantage: 1, owing to adopted the PP-R material, than traditional metallic water pipe, its cost is lower, flexibility is bigger, and is easy to connect; 2; Because water pipe is to be made up of the co-extrusion true qualities PP-R internal layer together PP-R skin with adding the lucifuge look female; Do not add the female internal layer of lucifuge look own and can intercept free the entering in the water of affix in the skin, thus polluted water not, and add lucifuge look female skin; Can prevent internal layer because of light ageing, improve the life-span; 3, composite bed can adopt the mode of co-extrusion to realize, composite bed can compensate the low temperature brittleness weakness of PP-R tubing to a certain extent, and than existing plastic-metal composite bed, it is processed more easily.
As preferred version, consider that internal layer just plays a buffer action, prevent free the entering in the water of affix in the skin, therefore do not need very high thickness, limiting described interior layer thickness is 0.2～0.4mm.
As preferred version, take all factors into consideration the isolation effect and the cost input of internal layer, limiting described interior layer thickness is 0.3mm.
Description of drawings
Fig. 1 is the cross sectional representation that the utility model embodiment meets water pipe.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model technological scheme is further specified:
As shown in Figure 1, the utility model provides a kind of compound water pipe, and the PP-R outer 2 with adding the lucifuge look female by co-extrusion true qualities PP-R internal layer 1 together constitutes, and wherein internal layer 1 thickness is 0.3mm.
According to the difference of water pipe diameter, and the difference of water pipe pressure-bearing demand, internal layer 1 thickness can be selected at 0.2～0.4mm.
The water pipe that meets of the utility model has following advantage: owing to adopted the PP-R material, than traditional metallic water pipe, its cost is lower, and flexibility is bigger, and is easy to connect; Because water pipe is to be made up of the co-extrusion true qualities PP-R internal layer together PP-R skin with adding the lucifuge look female; Do not add lucifuge look female internal layer own and can intercept free the entering in the water of affix in the skin; Thereby polluted water not; And add lucifuge look female skin, and can prevent internal layer because of light ageing, improve the life-span; Composite bed can adopt the mode of co-extrusion to realize, composite bed can compensate the low temperature brittleness weakness of PP-R tubing to a certain extent, and than existing plastic-metal composite bed, it is processed more easily.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
Claims (3)
1. a compound water pipe is characterized in that: be made up of co-extrusion true qualities PP-R internal layer together and the PP-R skin that adds lucifuge look mother.
2. compound water pipe according to claim 1 is characterized in that: layer thickness is 0.2～0.4mm in described.
