Abstract

本实用新型公开了一种平扩口聚乙烯双壁波纹管，它包括聚乙烯双壁波纹管(1)，聚乙烯双壁波纹管(1)的扩口部位(2)的管外径为其正常管径的1～1.1倍。本实用新型通过调整双壁波纹管扩口处和缩口处的结构，使双壁波纹管扩口处的管内径增大，管外径略增大或基本保持不变，或使双壁波纹管缩口处的管内径不变，管外径略减小或基本保持不变，经过如此调整后的本实用新型的整体外径基本相同，即可方便运输与存放，扩口与缩口内径的差异又可以满足插套连接，具有很好的使用价值和推广价值。

Description

一种平扩口聚乙烯双壁波纹管
技术领域
本实用新型涉及一种管材，特别是涉及一种平扩口聚乙烯双壁波纹管。
背景技术
现有聚乙烯双壁波纹管的连接均为插套连接，其连接方式为将聚乙烯双壁波纹管的一端加工为扩口，另一端加工为缩口，在缩口部位套接密封圈后与扩口相互插套连接，这种插套连接的聚乙烯双壁波纹管因管口端部的管径不同，导致该管件在存放和运输时彼此之间存在间隙，增加运输成本和存放空间。
实用新型内容
本实用新型要解决的技术问题是：提供一种方便运输及存储的平扩口聚乙烯双壁波纹管，可以克服现有技术的不足。
本实用新型的技术方案：它包括聚乙烯双壁波纹管，聚乙烯双壁波纹管的扩口部位的管外径为其正常管径的1～1.1倍。
聚乙烯双壁波纹管的缩口部位的管外径为其正常管径的0.9～1倍。
聚乙烯双壁波纹管的扩口部位的管外径为其正常管径的1～1.05倍。
聚乙烯双壁波纹管的缩口部位的管外径为其正常管径的0.95～1倍。
现有技术比较，本实用新型通过调整双壁波纹管扩口处和缩口处的结构，使双壁波纹管扩口部位的管内径增大，管外径略增大或基本保持不变，或使双壁波纹管缩口部位的管内径不变，管外径略减小或基本保持不变，经过如此调整后的本实用新型的整体外径基本相同，这样即可方便运输与存放，扩口与缩口内径的差异又可以满足插套连接，具有很好的使用价值和推广价值。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
实施例：如图1所示，在制作聚乙烯双壁波纹管1时调整双壁波纹管扩口处和缩口处的结构，使双壁波纹管1扩口部位2的管内径增大，管外径略增大或基本保持不变，其调整原则为根据管径的大小，扩口部位2的管外径不超过其正常管径的1～1.1倍，优选1～1.05倍。
或在调整扩口部位2外径的同时调整双壁波纹管缩口部位3的管径，其调整原则为：缩口部位3的管内径不变，管外径略减小或基本保持不变，其调整原则为：缩口部位3的管外径为其正常管径的0.9～1倍，优选0.95～1倍。
经过如此调整后的本实用新型的整体外径基本相同，这样即可方便运输与存放，扩口与缩口内径的差异又可以满足插套连接。
