Abstract

本实用新型公开了一种热熔接头,所述接头的端口处具有一个环状外层和环状内层,环状内层与接头的管路相通;所述环状外层和环状内层之间形成一个环形的热熔槽;所述环状内层的内壁上固定有一圈金属内衬。本实用新型工作时,管路套在环状内层的外壁上,位于热熔槽内,与接头熔接在一起。热熔时,环状内层上的金属内衬可以有效地防止环状内层变形,影响接头与管路的密封性以及管路的通畅性。

Description

一种热熔接头
技术领域
[0001] 本实用新型涉及一种连接管件,特别涉及一种热熔接头。
背景技术
[0002] 塑料管路一般通过各种接头连接,现今常用的连接方式是通过塑料热熔,管路与接头的连接处通过热熔连接在一起,其紧固性远远大于一般的螺纹连接。现有的热熔接头在经过加热熔接后,接头的内壁容易变形,与管路内壁产生空隙,也影响管路的畅通性。
发明内容
[0003] 本实用新型的目的是为了解决上述问题,提供一种结构简单、成本低廉,能使热熔后内壁不变形的热熔接头。
[0004] 为此,本实用新型的技术方案是:一种热熔接头,所述接头的端口处具有一个环状外层和环状内层,环状内层与接头的管路相通;所述环状外层和环状内层之间形成一个环形的热熔槽;其特征在于:所述环状内层的内壁上固定有一圈金属内衬。
[0005] 本实用新型工作时,管路套在环状内层的外壁上,位于热熔槽内,与接头熔接在一起。热熔时,环状内层上的金属内衬可以有效地防止环状内层变形,影响接头与管路的密封性以及管路的通畅性。
附图说明
[0006] 以下结合附图和本实用新型的实施方式来做进一步详细说明。
[0007] 图1为本实用新型的结构剖视图。
具体实施方式
[0008] 参见附图。本实施例所示的为热熔弯头,弯头的端口处均具有一个环状外层I和环状内层2,环状内层2与弯头的管路相通;所述环状外层I和环状内层2之间形成一个环形的热熔槽3 ;所述环状内层2的内壁上固定有一圈金属内衬4。
