   在用于油、气为介质的管路系统中,接头是必不可少的组成部分,液压快速接头的使用即提高了工作效率,也增加了安全性。液压快速接头的优点:

    液压快速接头是为特别的重负载设计,关键部件经过感应淬火,所以耐用性好。:采用两级密封,无泄漏 :带安全自锁功能。

  这种接头是一种既不需要使用工具,又能实现管路迅速装拆的接头,他有两端开闭式和两端开放式两种结构。拆卸方便,但结构较复杂,局部阻力损失较大,适用于油、气为介质的管路系统。
        
 
  两端开闭式快速接头由接头体、单向阀阀芯、外套、钢球、弹簧和密封等组成。接头体的内腔个有一个单向阀,当两个接头体分开离时,单向阀阀芯在各自的弹簧作用下外伸,并顶压在接头体的锥形孔上,使通路关闭,两边管子内的油被封闭在管中不能流出;当两个接头体连接时单向阀阀芯前端的两顶杆相碰,迫使阀芯离开接头体的锥形孔,使两边管子内的油相通,两个接头 体用钢球锁紧,工作时,外套在弹簧作用下把钢球压在接头体的U形槽内,使接头体连接。
 这种接头拆卸方便,但结构较复杂,局部阻力损失较大,适用于油、气为介质的管路系统。
 两端开放式快速接头,与两端开闭式的区别仅在于接头体内腔没有单向阀,当两个接头体分开时,不能封闭通路。接头的一端由三瓣式胶管接头与胶管相连,胶管接头的接头芯直接插入快速接头内。
