Description

A polyethylene foam insulation water delivery pipe

technical field

The utility model relates to a water delivery pipe, in particular to a polyethylene foam heat preservation water delivery pipe.

Background technique

Most of the existing water pipes are of single-body structure, which has poor thermal insulation performance and is easy to freeze when used in winter. Therefore, an additional insulation layer is required during use. Not only is the construction complicated, but also the outsourced insulation layer is prone to seepage and fall off, resulting in insulation loss. Reduced or lost performance.

Utility model content

Aiming at the defects existing in the prior art, the purpose of this utility model is to provide a polyethylene foam heat preservation water delivery pipe, which has a simple structure and low cost, adopts a multi-layer composite method, and the heat preservation layer and the protective layer are sequentially combined on the water delivery pipe The outer surface of the water pipe improves the thermal insulation of the water pipe, and at the same time enhances the anti-ultraviolet and anti-aging properties of the water pipe.

For achieving above object, the technical scheme that the utility model takes is:

A polyethylene foam heat preservation water delivery pipe, comprising a water delivery inner pipe 1, characterized in that: the outer surface of the water delivery inner pipe 1 is compounded with a PE foam insulation layer 2, and the outer surface of the PE foam insulation layer 2 is compounded with a PE Cable grade anti-UV protective layer3.

On the basis of the above-mentioned technical solution, the said inner water pipe 1 is a PB water pipe, a PE-X water pipe, a PP-R water pipe or a PE-RT water pipe.

On the basis of the above technical solution, the thickness of the PE foam insulation layer 2 is 4-12 mm, and the thickness of the PE cable-grade anti-ultraviolet protection layer 3 is 0.5-2.4 mm.

The polyethylene foam thermal insulation water delivery pipe described in the utility model has a simple structure and low cost, adopts a multi-layer composite method, and sequentially composites the thermal insulation layer and the protective layer on the outer surface of the water delivery pipe, thereby improving the heat preservation of the water delivery pipe. At the same time, it enhances the anti-ultraviolet and anti-aging performance of the water pipe.
