Description
本发明涉及一种管件连接结构，具体是一种即插快装管道连接组件。The invention relates to a pipe connection structure, in particular to a plug-in quick-installation pipe connection assembly.
以前的管件连接普遍采用螺纹式连接，通过卡环、密封圈等构件可以做到快速安装，但密封圈容易出现老化问题，影响密封效果，需要定期更换。后来出现卡箍式管件连接组件，比如“一种带有简易密封圈的管道连接装置”【CN205716120U】，结构升级，密封效果也很好；后来在管道连接装置里面增加了锁紧环结构，进一步增加了与管道之间的锁紧固定。但是以上的管道连接组件，都需要现场进行连接安装。锁紧环必须现场安装，将锁紧安装在下连接体上，将密封圈放在下连接体内，然后将两个管件放置相应的位置，将上连接体扣合并用螺栓螺母固定。In the past, the connection of pipe fittings generally used threaded connection, which can be installed quickly through components such as snap rings and sealing rings, but the sealing rings are prone to aging problems, which affect the sealing effect and need to be replaced regularly. Later, clamp-type pipe connection components appeared, such as "a pipe connection device with simple sealing ring" [CN205716120U]. The structure was upgraded and the sealing effect was also very good. Later, a locking ring structure was added to the pipe connection device. Increased the locking and fixing with the pipeline. However, the above pipeline connection components need to be connected and installed on site. The locking ring must be installed on site. The locking is installed on the lower connecting body, the sealing ring is placed in the lower connecting body, and the two pipe fittings are placed in corresponding positions, and the upper connecting body is buckled and fixed with bolts and nuts.
为了克服上述缺陷，本发明提供了一种即插快装管道连接组件，主要改变了锁紧环的结构，锁紧环分段设置并预先固定在上连接体和下连接体内，上连接体和下连接体仍然相对独立，可以通过螺母调整上连接体和下连接体之间的距离（而原有的C型锁紧环是无法预先放置在上连接体和下连接体之间的，只能现场安装，否则无法插入管件），管件插入后，旋紧螺母即可实现安装，安装非常便捷。In order to overcome the above shortcomings, the present invention provides a plug-in quick-installation pipeline connection assembly, which mainly changes the structure of the locking ring. The locking ring is arranged in sections and fixed in advance in the upper connecting body and the lower connecting body. The lower connecting body is still relatively independent, and the distance between the upper connecting body and the lower connecting body can be adjusted through the nut (and the original C-shaped locking ring cannot be placed between the upper connecting body and the lower connecting body in advance, but Install on site, otherwise the pipe cannot be inserted). After the pipe is inserted, the installation can be realized by tightening the nut, which is very convenient.
