AI Technical Summary

Technical Problem

Existing plastic pipes are prone to freezing and cracking in cold environments and have poor insulation effects, resulting in heat loss and additional labor hours.

Method used

Design a multi-layered plastic pipe material, including an inner tube body, an outer guard layer and a sandwich structure. The sandwich structure consists of a number of annular projections, an embedded thermal insulation protective layer and an aluminum alloy support ring, which improves the connection effect through coaxial arrangement and limiting grooves.

Benefits of technology

It effectively improves the insulation effect of the pipe, reduces the risk of freezing cracking, and reduces additional labor hours.

Abstract

The utility model discloses a pipe structure of a plastic pipe, which comprises an inner side pipe body, an outer side protective layer, an inner side protective layer, a plurality of outer side protective layers and a plurality of outer side protective layers, and the outer side protective layer and the inner side pipe body are coaxially arranged; the interlayer structure is located between the inner side pipe body and the outer side protection layer; the interlayer structure comprises a plurality of protruding parts, the protruding parts are of an annular structure, the protruding parts are evenly distributed in the axis direction of the inner side pipe body, and a concave part is formed between every two adjacent protruding parts. And the protective layer is embedded in the concave part, and the protective layer is wrapped in the convex part. Wherein the protective layer is made of a thermal insulation material, and the protective layer is fixedly connected with the outer protective layer. According to the utility model, the problems that the existing single-material pipe is poor in heat preservation effect and easy to crack in the actual use process can be effectively solved.
