Abstract

一种管材密封堵头,其特征是它由双头螺栓、弹性套、密封垫、内、外螺母组成。密封垫、弹性套自双头螺栓内端依次卡套在双头螺栓外圆上,双头螺栓内、外两端分别旋入内、外螺母,双头螺栓外端有调整方头。安装时,将内螺母及卡套弹性套的双头螺栓部分伸入管材的端口内,使用扳手固定双头螺栓外端的调整方头,缓慢旋紧外螺母,压缩弹性套外径扩胀,从而起到密封作用。密封效果好,适用范围广,特别适合薄壁、小口径、异形管材使用。

Description

管材密封堵头
技术领域
[0001] 本实用新型涉及一种管接头,特别是一种管材密封堵头。 背景技术
[0002] 现有的管材密封堵头与管材之间是通过螺纹连接而将管道密封,管材端口须加工螺纹,而对于薄壁、小口径、异形等管材则无法进行攻丝加工,因此现有的管材堵头不能适应此类管材使用。
发明内容
[0003] 本实用新型的目的是为了克服上述不足之处,而提供一种密封效果好,适用范围广,特别适合薄壁、小口径、异形管材使用的管材密封堵头。
[0004] 本实用新型的目的是这样实现的:一种管材密封堵头,其特征是它由双头螺栓、 弹性套、密封垫、内、外螺母组成,密封垫、弹性套自双头螺栓内端依次卡套在双头螺栓外圆上,双头螺栓内、外两端分别旋入内、外螺母,双头螺栓外端有调整方头。
[0005] 本实用新型由于采用以上设计,安装时,将内螺母及卡套弹性套的双头螺栓部分伸入管材的端口内,使用扳手固定双头螺栓外端的调整方头,缓慢旋紧外螺母,压缩弹性套外径扩胀,从而起到密封作用。密封效果好,适用范围广,特别适合薄壁、小口径、异形管材使用。
附图说明
[0006] 图1为本实用新型结构示意图。 具体实施方式
[0007] 现结合附图所示实施例对本实用新型作出详细说明。
[0008] 如图1所示,管材密封堵头由双头螺栓2、弹性橡胶套5、密封橡胶垫4、圆内螺母 6、六角外螺母3组成。密封橡胶垫4、弹性橡胶套5自双头螺栓2内端依次卡套在双头螺栓 2外圆上,双头螺栓2内、外两端分别旋入圆内螺母6、六角外螺母3,圆内螺母6、弹性橡胶套5直径略小于管材内径,密封橡胶垫4的内孔紧贴双头螺栓2外圆,双头螺栓2外端有调整方头1。
