这是一种安装方式。安装拆卸简单方便，安装速度快，同时具有温度伸缩补偿功能，可以省略较长管线中的伸缩器。柔性管接头同时具有一定的角度补偿功能，管线中角度较小的拐点处可以不设弯头，使用管接头调整角度。

It is one of high efficient and rapid installation connection. I t has the below characteristic: Easily install and disassemble, fast installation, temperature adjustable compensation function, saving the necessary expansion in long pipeline. Easy-flexible joint also has angle compensation characteristic. At smaller angle turning points, easy-flexible joint can be instead of bends and adjust angle.
