Description

无螺纹密封法兰
技术领域
本实用新型涉及一种无螺纹密封法兰。
背景技术
现有的技术中,无螺纹密封法兰被广泛运用于管道行业,但是在一般的管道连接过程中,如果管道事先没有设置法兰,就很难进行连接,这样就很难进行连接,容易出现泄漏。
实用新型内容
    本实用新型提供一种可以方便管道口部没有设置法兰的管道进行对接,密封性好的无螺纹密封法兰。
本实用新型解决技术问题提供如下方案:
一种无螺纹密封法兰,包括法兰盘,其特征在于:所述法兰盘的中部设有通孔,所述通孔四周设有台阶槽,所述台阶槽的底部设有卡槽,所述卡槽内设有密封圈,所述通孔的四周设有楔形槽,所述楔形槽内放置有楔形铁。
所述法兰盘的边缘四周设有螺栓孔。
本实用新型在传统的法兰基础上,在法兰的中心设有密封凹槽,在密封凹槽内添加密封圈,且在密封圈的内圈四周设有楔形铁对密封圈进行挤压,有效避免了管道接口处的泄露。
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,一种无螺纹密封法兰,包括法兰盘1,所述法兰盘1的中部设有通孔2,所述通孔2四周设有台阶槽3,所述台阶槽3的底部设有卡槽4,所述卡槽4内设有密封圈5,所述通孔2的四周设有楔形槽7,所述楔形槽7内放置有楔形铁8,所述法兰盘1的边缘四周设有螺栓孔6。

Claims (2)

1.一种无螺纹密封法兰,包括法兰盘,其特征在于:所述法兰盘的中部设有通孔,所述通孔四周设有台阶槽,所述台阶槽的底部设有卡槽,所述卡槽内设有密封圈,所述通孔的四周设有楔形槽,所述楔形槽内放置有楔形铁。
2.根据权利要求1所述无螺纹密封法兰,其特征在于:所述法兰盘的边缘四周设有螺栓孔。
