Description

Pe automatically cleaning drinking water conveying pipe

Technical field:

This utility model is related to a kind of pe automatically cleaning drinking water conveying pipe.

Background technology:

Feedwater is the regeneration product of traditional iron and steel tubing, polrvinyl chloride drinking-water pipe with pe tubing.

Feed pipe must endure as certain pressure, and molecular weight generally to be selected is big, the pe resin of better mechanical property, such as Hdpe resin.The tensile strength of ldpe resin is low, resistance to pressure reduction, poor rigidity, poor dimensional stability during processing and forming, and connects tired Difficulty, is not suitable for the material as feed pressure pipe.But because its sanitary index is higher, pe particularly hdpe resin has become production The common used material of drinking-water pipe.The melt viscosity of hdpe resin is little, good fluidity, easy processing, thus the choosing to its melt index (MI) Select scope also wider, usual mi is between 0.3-3g/10min.

Utility model content:

The purpose of this utility model is above in order to overcome the shortcomings of, provides a kind of fouling that can reduce tubing now As extending the pe automatically cleaning drinking water conveying pipe of system service life.

The purpose of this utility model is achieved through the following technical solutions: a kind of pe automatically cleaning drinking water conveying pipe, including Body, body includes pe outer layer, pe internal layer and antibiotic layer, and pe outer layer, pe internal layer and antibiotic layer are distributed outside to inside by body, antibacterial Layer inner surface is provided with multiple projections, and projection section is triangle, and antibacterial layer surface is additionally provided with multiple through holes.

Preferably, number of slugs is four, and number of openings is six.

Preferably, tube length is 4m ~ 6m.

This utility model compared with prior art has the advantage that: reduces the scale formation of tubing, prolongation system makes Use the life-span.

Brief description:

Fig. 1 is structure chart of the present utility model；

In figure label: 1-pe outer layer, 2- pe internal layer, 3- antibiotic layer, 4- projection, 5- through hole.

Specific embodiment:

In order to deepen, to understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, this utility model to be made further Describe in detail, this embodiment is only used for explaining this utility model, does not constitute the restriction to this utility model protection domain.

A kind of pe automatically cleaning drinking water conveying pipe as shown in Figure 1, including body, body includes pe outer layer 1, pe internal layer 2 and Antibiotic layer 3, pe outer layer 1, pe internal layer 2 and antibiotic layer 3 are distributed outside to inside by body, and antibiotic layer 3 inner surface is provided with multiple projections 4, Projection 4 section is triangle, and antibiotic layer 3 surface is additionally provided with multiple through holes 5.

Projection 4 quantity is four, can effectively keep out the dirt being attached on tube wall, and through hole 5 quantity is six, can be to pipe In road, water quality is cleaned.

Tube length is 4m ~ 6m.

The another statement of applicant, this utility model illustrates implementation method of the present utility model and dress by above-described embodiment Put structure, but this utility model is not limited to above-mentioned embodiment, that is, do not mean that this utility model has to rely on above-mentioned side Method and structure could be implemented.Person of ordinary skill in the field it will be clearly understood that to any improvement of the present utility model, to this reality With the interpolation of new selected implementation method equivalence replacement and step, selection of concrete mode etc., all fall within of the present utility model Within protection domain and scope of disclosure.

This utility model is not limited to above-mentioned embodiment, and all employing is come in fact with this utility model analog structure and its method All modes of existing this utility model purpose, all within protection domain of the present utility model.
