Abstract

本实用新型涉及一种管道连接件。它包括管状连接体，拧在连接体上的螺帽，置于螺帽内压紧且并排套在被连接管体上的紧固圈、压垫、横截面形状为矩形体和直角三角形体组成的密封圈，具有密封可靠的特点。

Description

管道连接件
技术领域
    本实用新型涉及一种管道连接件。
背景技术
    在已有技术中，管道连接件包括管状连接体，拧在连接体上的螺帽，置于螺帽内压紧且并排套在被连接管体上的紧固圈、压垫、O型密封圈，其缺点是O型密封圈密封面积小，又当管件不规矩时，连接处的密封容易泄漏。
实用新型内容
    本实用新型的目的是针对上述不足而提供一种改善密封效果的管道连接件。
    本实用新型的技术解决方案是：管道连接件包括管状连接体，拧在连接体上的螺帽，置于螺帽内压紧且并排套在被连接管体上的紧固圈、压垫、密封圈。改进之处是密封圈的形状，即其横截面形状由矩形体和直角三角形体两部分组成，密封圈前部为直角三角形体，密封圈后部为矩形体。。
    本实用新型的优点是：密封圈的前部为直角三角形，增加了密封部位接触面积；在密封圈后部增加了矩形体，不仅又增加了密封接触面积，同时更重要的是增加了垂直压合密封面，密封更紧密，使密封效果达到最佳，确保使用中不泄漏，实现了本发明的目的。
附图说明
下面将结合附图对本实用新型作进一步详细描述。
    图1是本实用新型的结构简图。
具体实施方式
    参见图1，以“三通管件”为例，在每通上都有连接接头。管道连接件由管状连接体1、拧在连接体1上的螺帽2、置于螺帽2内压紧且并排套在被连接管体6（PE管）上的紧固圈3、压垫4、密封圈5组成。密封圈5横截面形状由矩形体和直角三角形体两部分组成，前部为直角三角形体，密封圈后部为矩形体。管体6是用来被连接的。管件还可以是弯头、管箍、四通、活结、阀门等管路连接件。
