Abstract
The utility model relates to a kind of water-feeding pipes, comprises interior tube layer and external tube layer, and described external tube layer is coated on the periphery of interior tube layer, and described external tube layer is polyvinyl chloride layer, and interior tube layer is polyethylene layer, and the Thickness Ratio of interior tube layer, external tube layer is 3:7.The interior tube layer that the water-feeding pipes that the utility model provides and water body directly contact is polyethylene layer, polyethylene layer can not pollute water body, external tube layer is polyvinyl chloride layer, the mechanical strength of polyvinyl chloride layer is large, therefore this water-feeding pipes has nontoxic, the feature that mechanical strength is large, simultaneously because interior tube layer directly contacts with water body, in in the process used, the loss of tube layer is low, therefore the thickness of interior tube layer can arrange less, and external tube layer contacts with foreign object, its loss is relatively large, therefore the thickness of external tube layer can arrange larger, make supply pipe while mechanical strength increases, also more through with.Above best results when the Thickness Ratio of interior tube layer, external tube layer is 3:7.
Description
Technical field
The utility model relates to water supply facilities field, more specifically, relates to a kind of water-feeding pipes.
Background technique
Compared with traditional cast iron, zinc-plated pipeline, the advantages such as plastic pipe is lightweight with it, corrosion-resistant, resistance to water-flow is little, energy saving, installation is fast, cost is low, are subject to wideling popularize application, remarkable benefit.In municipal water supply field, plastic pipe mainly contains polychloroethylene pipes and polyvinyl piping materials, compared with polyvinyl piping materials, polychloroethylene pipes has cheap, mechanical strength is large, and (polychloroethylene pipes tensile strength can reach 40MPa, polyvinyl piping materials tensile strength 20 ~ 24 MPa), equivalent specifications pressure wall thickness thin compared with polyvinyl piping materials (water-flowing amount is large), can directly landfill and the not easily advantage such as scuffing, but polychloroethylene pipes main raw material is PVC＝polyvinyl chloride, this kind of tubing can separate out chlorion when in use, human body is damaged, the serviceability temperature scope of polychloroethylene pipes is narrower simultaneously, easily break because of the expansion of water body in pipeline when cold weather.Due to the existence of above shortcoming, polychloroethylene pipes, in feedwater field, is applied not extensive.
And polyvinyl piping materials has nontoxic, the in use not advantage such as breed bacteria, and its good toughness, serviceability temperature wider range.But polyvinyl piping materials price is higher, poor rigidity, surface easily scratch, to construction landfill requirement high (first must spread fine sand, prevent tubing from scratching).
Therefore, market is badly in need of one and both can not produces pollution to water quality, there is again higher mechanical strength water-feeding pipes.
Model utility content
The utility model is the defect solving above prior art, provide a kind of water-feeding pipes, this water-feeding pipes is by external tube layer and interior tube layer is coated forms, in wherein directly contacting with water body, tube layer is polyethylene layer, polyethylene layer can not pollute water body, and external tube layer is polyvinyl chloride layer, and the mechanical strength of polyvinyl chloride layer is large, therefore this water-feeding pipes has nontoxic, that mechanical strength is large feature, overcomes the defect of prior art.
For realizing above model utility object, the technological scheme of employing is as follows:
A kind of water-feeding pipes, comprise interior tube layer and external tube layer, described external tube layer is coated on the periphery of interior tube layer, and described external tube layer is polyvinyl chloride layer, and interior tube layer is polyethylene layer, and the Thickness Ratio of interior tube layer, external tube layer is 3:7.
In such scheme, in directly contacting with water body, tube layer is polyethylene layer, polyethylene layer can not pollute water body, external tube layer is polyvinyl chloride layer, the mechanical strength of polyvinyl chloride layer is large, therefore this water-feeding pipes has nontoxic, the feature that mechanical strength is large, simultaneously because interior tube layer directly contacts with water body, in in the process used, the loss of tube layer is low, therefore the thickness of interior tube layer can arrange less, and external tube layer contacts with foreign object, its loss is relatively large, therefore the thickness of external tube layer can arrange larger, make supply pipe while mechanical strength increases, also more through with.Above best results when the Thickness Ratio of interior tube layer, external tube layer is 3:7.
Preferably, the surface of contact between described external tube layer and interior tube layer is the male and fomale(M&F) cooperatively interacted.Interior tube layer, external tube layer, by the interaction of male and fomale(M&F), are avoided interior tube layer, external tube layer are easily skidded off from pipe end, ensure the stable of pipe structure.
Preferably, the surface of contact between described external tube layer and interior tube layer is along the axial indentation of tubing.
Preferably, the surface of contact between described external tube layer and interior tube layer is wavy along the axis of tubing.
Preferably, in order to strengthen the stability that external tube layer is combined with interior tube layer, between described external tube layer and interior tube layer, also bond coat is provided with.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
The water-feeding pipes that the utility model provides is by external tube layer and interior tube layer is coated forms, in wherein directly contacting with water body, tube layer is polyethylene layer, polyethylene layer can not pollute water body, external tube layer is polyvinyl chloride layer, the mechanical strength of polyvinyl chloride layer is large, therefore this water-feeding pipes has nontoxic, the feature that mechanical strength is large, simultaneously because interior tube layer directly contacts with water body, in in the process used, the loss of tube layer is low, therefore the thickness of interior tube layer can arrange less, and external tube layer contacts with foreign object, its loss is relatively large, therefore the thickness of external tube layer can arrange larger, make supply pipe while mechanical strength increases, also more through with.Above best results when the Thickness Ratio of interior tube layer, external tube layer is 3:7.
Accompanying drawing explanation
Fig. 1 is the structural representation of water-feeding pipes.
Embodiment
Accompanying drawing and embodiment, only for exemplary illustration, can not be interpreted as the restriction to this patent;
Embodiment 1
The utility model provides a kind of water-feeding pipes, and as shown in Figure 1, comprise interior tube layer 1 and external tube layer 2, external tube layer 2 is coated on the periphery of interior tube layer 1, and external tube layer 2 is polyvinyl chloride layer, and interior tube layer 1 is polyethylene layer, and the Thickness Ratio of interior tube layer, external tube layer is 3:7.
In such scheme, in directly contacting with water body, tube layer 1 is polyethylene layer, polyethylene layer can not pollute water body, external tube layer 2 is polyvinyl chloride layer, the mechanical strength of polyvinyl chloride layer is large, therefore this water-feeding pipes has nontoxic, the feature that mechanical strength is large, simultaneously because interior tube layer 1 directly contacts with water body, in in the process used, the loss of tube layer 1 is low, therefore can the thickness of interior tube layer 1 be arranged less, and external tube layer 2 contacts with foreign object, its loss is relatively large, therefore can the thickness of external tube layer 2 be arranged larger, make water-feeding pipes while mechanical strength increases, also more through with.Above best results when the Thickness Ratio of interior tube layer 1, external tube layer 2 is 3:7.
