Abstract

本实用新型涉及一种导水管活络接头,主要解决现有活络接头存在的密封性能差、转动欠灵活、使用寿命短的缺点。其特征是旋转短管的外侧起有一圈凸台,凸台的上方和下方均装有一圈滚珠,两圈滚珠分别通过上压圈和下压圈固定,上压圈通过拉杆与管座连接,下压圈压住密封圈。本实用新型用于活动式取水设施上,尤其是水上水厂。

Description

双向定位活络接头
本实用新型涉及一种活动式取水设施上使用的活络接头,尤其是广泛用于水上水厂以适应江河水位的变幅,保证向固定管路连续供水。
现有的球形式或套筒式活络接头由于受力、承压及密封互有干扰,存在密封性能差,转动欠灵活,使用寿命短的缺点。
本实用新型的目的是提供一种结构合理,受力均衡,转动灵活,密封止水效果好,使用寿命长的双向定位活络接头。
本实用新型包括管座、密封圈和旋转短管。
本实用新型是这样实现的:旋转短管的外侧起有一圈凸台,凸台的上方和下方均装有一圈滚珠,两圈滚珠分别通过上压圈和下压圈固定,上压圈通过拉杆与管座连接,下压圈压住密封圈。
本实用新型采用双向滚动支承定位,使其在旋转动作中保证密封圈工作间隙,使得受力均衡,止水可靠、使用寿命长、转动灵活,并且节省运行费和检修费。
附图为本实用新型结构示意图,1——管座,2——密封圈,3——旋转短管,4——凸台,5——滚珠、6——上压圈,7——下压圈,8——拉杆。
实施例:
本实用新型采用A3钢制造、其中旋转短管3的内径600mm、高540mm,滚珠5为直径38.1mm的钢球、共64个、每圈32个,按前述方式组装各部件即成为本实用新型。
