Abstract

本发明公布了一种管接头，包括插口和套口，其特征在于：所述套口与插口螺旋连接，所述套口与插口之间具有密封圈，所述密封圈外部包裹有毛发纤维编织层。所述密封圈本体为O形橡胶密封圈或四氟乙烯密封圈或石墨密封圈。本发明将普通密封圈替换为外部包裹有毛发纤维编织层的密封圈。利用毛发纤维的大的表面张力和耐腐蚀性，从而使得管接头的密封圈在老化或腐蚀后仍能够保证良好的密封性，大大提高了管接头的使用寿命和密封效果。

Description

一种管接头
技术领域
本发明涉及一种管接头。
背景技术
现有的管接头常见的形式是螺纹连接的套口和插口，套口和插口之间具有密封圈，现有的密封圈材质多种多样，有橡胶材质、四氟乙烯材质和石墨材质等，适用于不同的高温、高压、腐蚀性场合。但是这些密封圈在使用一段时间后都会产生不同程度的老化、腐蚀，造成泄漏。
发明内容
本发明目的在于针对现有技术的缺陷提供一种密封效果好，使用寿命长的管接头。
本发明为实现上述目的，采用如下技术方案：
一种管接头，包括插口和套口，其特征在于：所述套口与插口螺旋连接，所述套口与插口之间具有密封圈，所述密封圈外部包裹有毛发纤维编织层。
其进一步特征在于：所述密封圈本体为O形橡胶密封圈或四氟乙烯密封圈或石墨密封圈。
本发明将普通密封圈替换为外部包裹有毛发纤维编织层的密封圈。利用毛发纤维的大的表面张力和耐腐蚀性，从而使得管接头的密封圈在老化或腐蚀后仍能够保证良好的密封性，大大提高了管接头的使用寿命和密封效果。
附图说明
图 1 为本发明示意图。
图 2 为密封圈结构示意图。
具体实施方式
如图1所示一种管接头，包括插口4和套口3，所述套口3与插口4螺旋连接，所述套口3与插口4之间具有密封圈1，所述密封圈1外部包裹有毛发纤维编织层2（如图2所示）。所述密封圈1本体为O形橡胶密封圈或四氟乙烯密封圈或石墨密封圈。
由于密封圈外部包裹有毛发纤维编织层。利用毛发纤维的大的表面张力可以大大提高密封圈的密封效果。同时当密封圈本体在使用一段时间后老化、腐蚀时，由于外部的毛发纤维具有良好的耐腐蚀性和密封效果，这时整个密封圈还可以进行良好的密封，从而大大提高了整个管接头的密封效果和使用寿命。

Claims (2)
