Abstract

本实用新型提供一种结构合理，使用方便，密封性好的法兰接头，包括两接头体、左、右法兰，其特征在于：所述两接头体的中心设有通孔，所述两接头体对接时左、右两端为管道连接口，所述接头体的外壁上设有凸台，所述两接头体通过左、右两法兰固定连接在一起，所述两接头体凸台卡接在左、右法兰的卡槽内。本实用新型采用内外双层结构，通过左、右法兰对接形成的卡槽来将接头体固定连接在一起，结构更加牢固，密封性好。

Description

法兰接头
技术领域
 本实用新型涉及一种法兰接头。
背景技术
法兰结构形式多种多样，绝大多数的法兰接为左右法兰对接连接，且在对接端面上设置密封圈保证密封性，但是由于密封圈的寿命有限，长时间的使用容易导致泄漏。
实用新型内容
本实用新型提供一种结构合理，使用方便，密封性好的法兰接头。
本实用新型解决技术问题提供如下方案：
 一种法兰接头，包括两接头体、左、右法兰，其特征在于：所述两接头体的中心设有通孔，所述两接头体对接时左、右两端为管道连接口，所述接头体的外壁上设有凸台，所述两接头体通过左、右两法兰固定连接在一起，所述两接头体凸台卡接在左、右法兰的卡槽内。
所述左、右法兰通过螺栓和螺母连接在一起。
本实用新型采用内外双层结构，通过左、右法兰对接形成的卡槽来将接头体固定连接在一起，结构更加牢固，密封性好。
附图说明
图1 为本实用新型的结构示意图。
具体实施方式
 参见附图，一种法兰接头，包括两接头体1、左、右法兰2、3，所述两接头体1 的中心设有通孔4，所述两接头体1 对接时左、右两端为管道连接口5，所述接头体1 的外壁上设有凸台6，所述两接头体1 通过左、右两法兰2、3 固定连接在一起，所述两接头体凸台6 卡接在左、右法兰2、3 的卡槽内，所述左、右法2、3 兰通过螺栓和螺母连接在一起。
