Abstract

The utility model relates to a drinking water pipe, particularly a plastic compounded water drinking pipe. The utility model comprises a plastic outer pipe. The utility model is characterized in that an innocuous plastic layer is arranged in the plastic outer pipe; the innocuous plastic layer is inlaid to be stuck on the inner surface of the plastic outer pipe by a plurality of matched grooves and convex bars which are respectively arranged on the inner surface of the plastic outer pipe and the outer surface of the innocuous plastic layer. The utility model has the advantages of innocuity, low cost, light resistance, high rigidity, environment resistance, convenient construction and installation, etc. The utility model is a green product, and is an ideal product for replacement.

Description

The compound water drinking tube of plastics

The utility model relates to a kind of water drinking tube, the compound water drinking tube of particularly a kind of plastics.

Existing plastics water drinking tube, otherwise cost an arm and a leg, installation is extremely inconvenient, or also contains little poison.As: the PPR pipe, though can thoroughly solve the water pipe pollution problem of potable water, price is high and must use the installation of machinery ability.Though PVC-U pipe is cheap, installation convenient, PPN is meeting NBS below 3; But poisonous, still harmful, particularly the long-term drinking water harm of should pipe carrying is bigger, because of the water of carrying can directly contact with PVC-U, can dissolve PPN wherein.

At above problem, the purpose of this utility model provides the convenient and nontoxic compound water drinking tube of plastics of a kind of cheap, installation.

The compound water drinking tube of a kind of plastics comprises plastic outer tube, and its main points are: also be provided with the non-toxic plastic layer in plastic outer tube.The non-toxic plastic layer can be that plug is contained in the interior pipe of non-toxic plastic in the plastic outer tube, also fits tightly the non-toxic plastic layer on the plastic outer tube internal surface.To make it occupation space little for the size that saves material, reduces cost and fully guarantee bore, preferably adopts the non-toxic plastic layer that fits tightly on the plastic outer tube internal surface.

The purpose of this utility model realizes by establish dress non-toxic plastic separation layer in plastic outer tube.So, the water of conveying is not contacted with plastic outer tube, even the poisonous water quality that also can not influence transporting water of plastic outer tube guarantees that it is nontoxic, thoroughly solved the water pipe pollution problem of potable water; Energy adopts cheap, fast light photograph, high hardness, anti-environment, is convenient to the plastic outer tube of construction and installation.Having advantages such as nontoxic, cheap, fast light photograph, hardness height, anti-environment, construction install convenience, is a kind of green product, is a kind of desirable substitute products.

Describe in detail below in conjunction with embodiment and accompanying drawing thereof:

Fig. 1 is a structural representation of the present utility model.

Among the figure: (1) plastic outer tube, (2) non-toxic plastic layer, (3) groove, (4) raised line.

Among the figure a kind of structural section figure of the present utility model.Water drinking tube among the figure is the compound water drinking tube of a kind of PVC-U and HDPE, and promptly plastic outer tube (1) is the PVC-U pipe, and non-toxic plastic layer (2) is the HDPE layer.

To make it occupation space little for the size that saves material, reduces cost and fully guarantee bore, adopted the non-toxic plastic layer (2) that fits tightly on plastic outer tube (1) internal surface among the figure.For the ease of straight forming and non-toxic plastic layer (2) embedding firmly is attached on the internal surface of plastic outer tube (1), among the figure be utilize be located at respectively on plastic outer tube (1) internal surface and non-toxic plastic layer (2) outer surface on some the grooves that match (3) and raised line (4) make non-toxic plastic layer (2) closely embedding be attached on the internal surface of plastic outer tube (1), promptly the raised line (4) that matches of non-toxic plastic layer (2) some grooves (3) that to be some of utilizing that its outer surface is provided be provided with plastic outer tube (1) internal surface or raised line (4) or groove (3) closely embedding be attached on the internal surface of plastic outer tube (2); Obviously, non-toxic plastic layer (2) also can directly be glued on the internal surface of plastic outer tube (1).

Groove among the figure (3) is located on the internal surface of plastic outer tube (1), and raised line (4) is located on the outer surface of non-toxic plastic layer (2).Can not only reduce cost greatly like this and can also fully guarantee the hardness of water drinking tube.HDPE non-toxic plastic layer (2) in the compound water drinking tube of PVC-U among the figure and HDPE is very thin, only is 0.5 millimeter, and cost is close with pure PVC-U plastic tube.Obviously,, also groove (3) can be located on the outer surface of non-toxic plastic layer (2), raised line (4) is located on the internal surface of plastic outer tube (1) if when non-toxic plastic layer (2) is very thick.For non-toxic plastic layer (2) embedding more firmly is attached on the internal surface of plastic outer tube (1), having adopted the cross section among the figure is the groove (3) and the raised line (4) of T shape.
