Abstract

吸水膨胀的复合密封圈涉及密封件。其内圈(1)外套有外圈(2)。具有结构简单紧凑,材料易得,加工方便,使用效果好等特点。用于水管之间密封。

Description

吸水膨胀的复合密封圈
技术领域
本实用新型涉及密封件,尤其是一种吸水膨胀的复合密封圈。
背景技术
现有密封件是单层结构,完全靠自身弹性进行紧固密封,但密封效果有限,其效果还是不理想。
发明内容
本实用新型的目的是提供一种结构简单,采用复合双层结构,能吸水自行膨胀的密封圈。
本实用新型的目的所采用技术方案是,由吸水材料和橡胶十几种材料加工而成的内圈、橡胶制成的外圈组成,其内圈外套有外圈。
本实用新型,所述的外圈环形壁未封口。
本实用新型具有结构简单紧凑,材料易得,加工方便,使用效果好等特点。
附图说明
下面结合附图进一步说明本实用新型。
附图是本实用新型断面剖视结构示意图。
图中:1-内圈    2-外圈
具体实施方式
见附图,内圈1从外圈2环形壁未封口的缝隙装入圈内。
使用时,装配在水管与水管之间,一旦有水,使内圈1吸水材料吸水,迅速膨胀,并把水份储存起来,最多可以储存400倍于本身重量的水,这样压紧弹性橡胶外圈2,其两水管之间密封效果好,有效防止渗水漏水。吸水材料也有称膨胀粉。

Claims (2)

1.一种吸水膨胀的复合密封圈,由内圈(1)、橡胶制成的外圈(2)组成,其特征是内圈(1)外套有外圈(2)。
2.根据权利要求1所述的一种吸水膨胀的复合密封圈,其特征是所述的外圈(2)环形壁未封口。
