Abstract

本实用新型公开了一种带颈平焊法兰,包括左、右两法兰盘,其特征在于:所述左法兰盘的右端面设有内管,所述右法兰盘的左端设有外管,所述外管套在内管外,且外管的内壁上设有限位环,所述外管和限位环的侧壁上分别设有密封圈。本实用新型连接牢固、稳定性好,不容易泄露。

Description

带颈平焊法兰
技术领域
本实用新型涉及一种带颈平焊法兰。
背景技术
    现有技术中,管路与阀门之间、管路与管路之间的连接一般都是将管子与阀门或者法兰之间直接焊接,从而达到密封目的,传统的法兰由于结构设计存在缺陷,导致在使用过程中容易出现法兰接头处容易松动泄露。
实用新型内容
本实用新型目的是提供了一种连接牢固、稳定性好,不容易泄露的带颈平焊法兰。
本实用新型解决技术问题提供如下方案:
一种带颈平焊法兰,包括左、右两法兰盘,其特征在于:所述左法兰盘的右端面设有内管,所述右法兰盘的左端设有外管,所述外管套在内管外,且外管的内壁上设有限位环,所述外管和限位环的侧壁上分别设有密封圈。
所述左法兰的左端设有连接管套。
本实用新型在左、右两法兰盘的相邻端面上分别设有内管和外管,且内管位于外管内,且在外管的内壁上设有限位环,且在限位环上和外管的内壁上设有密封圈,这样管道之间的密封性能大大提高了,且同时内管与外管之间的对接式连接方式,也使得管道连接更加稳定不易松动。
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,一种带颈平焊法兰,包括左、右两法兰盘1、2,所述左法兰盘1的右端面设有内管3,所述右法兰盘3的左端设有外管4,所述外管4套在内管外,且外管4的内壁上设有限位环5,所述外管4和限位环5的侧壁上分别设有密封圈6。
所述左法兰1的左端设有连接管套7。
