Abstract

本实用新型涉及波纹管,所述波纹管包括内管层和外管层,所述外管层形成外凸内凹形,内管层为直筒形,内管层和外管层通过复合溶固。本实用新型由于有外管层的中空腔,起到进一步的保温隔热作用,保温效果较好。

Description

波纹管
技术领域
本实用新型涉及管道,尤其是塑料波纹管。
背景技术
塑料波纹管主要用于地下预埋管道,在市政、桥梁、铁路等领域使用较多。在家装过程中,在室内地下需要预埋热水管道,一般与冷水管道材质相同,都是由PVC或聚乙烯制成的单壁结构管道,因此不利于热水保温,通常也有保温措施,但需要额外的施工步骤。
实用新型内容
本实用新型的目的在于提供一种保温效果较好的波纹管。
本实用新型的目的是通过如下技术方案来完成的,波纹管,其特征在于:所述波纹管包括内管层和外管层,所述外管层形成外凸内凹形,内管层为直筒形,内管层和外管层通过复合溶固。
    本实用新型波纹管为双层结构,使用在室内热水管道中起到一定的保温隔热作用,同时外管层为外凸内凹波纹型,而内管层为直筒形,并且内外管层复合溶固,与现有技术相比,由于有外管层的中空腔,起到进一步的保温隔热作用,保温效果较好。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
下面将结合附图对本实用新型做详细的介绍:
如图1所示:波纹管,所述波纹管包括内管层1和外管层2,所述外管层形成外凸内凹形,内管层为直筒形,内管层和外管层通过复合溶固,内外层都由PVC材料构成。
