2． 通过横向的定位轴锁定顺、逆流管与上接头，再加以上盖的结构，极大地缩短了装配时间。
3． 带有万向球头的支臂接头使安装和使用时都具有相当的便利性，因为整个装置可以自由转动和具有一定程度的轴向偏离。
4． 顺、逆流管的双向并行结构可以直接通过低位的设备选择输出，可不需额外的阀门部件切换即可完成切换，结构简单可靠。
5． 顺、逆流管采用纵向隔层于一体成型管件的形态，装配部件更少、工序更简单。

具体实施方式
实施例一
如图1、图2、图3所示，为本发明快装三通接头的一个实施例；支臂400为标准件，从墙体侧面伸出，通过一个支臂接头210连接阀体100。支臂接头210可以有多种形态，只要能将支臂400的水路与阀体100连通即可。本例中运用了球头214的结构，通过过水件211、螺母212、衬套213和球面垫圈215，支臂400与阀体100为可活动的安装形态，适用多种场合。
下管组件包括了顺流管104和逆流管103。顺流管104嵌套于逆流管103内，两管长度相当，通过上接头110固定了两者上端，下端通过下接头120固定。上接头110在阀体100内将顺、逆流管固定以后，另有一个上盖109将阀体100封闭。在下接头120的外部还固定一个切换件130。
实际安装时，可以是如下的顺序：
先将顺流管104嵌套于逆流管103，通过下管口203穿过阀体100；然后将上接头110插入顺、逆流管后，定位轴105横向将三者锁定，于是将三者自安装口107拉回阀体100，在安装口107处固定上盖109，即完成主体的安装。接下来可以连接支臂400，即将过水件211拧于支臂400末端，在过水件211自由端套上螺母212和衬套213，再拧上球头214，最后把球头垫圈215置于球头214和阀体100之间，最终拧紧螺母212即可把装置固定于支臂400。
至于阀体100上的出水口202，用于预留与高位的设备比如头部花洒连接；下接头120外部的切换件130是与低位的设备比如手持花洒连接，这都可以在装置固定好以后再处理。切换件130内部可以只有一个空腔，使来自顺、逆流管的水流混合输出即可，因为当切换件130连接的手持花洒打开时，来自支臂400的水流无阻碍地从下接头120以及切换件130流出，不会再进入逆流管103以至于流到202，如此就已经可以满足仅使用低位设备的需求。但本例中切换件130具有阀门的结构，可以阻塞水流从下接头120处沿逆流管103内壁返回阀体，因此更加可靠地分离了高、低位设备，当切换阀打开，且低位设备关闭时，水流可以无碍地沿逆流管103内壁返回，直至从出水口202流出到高位设备。
图2是实施例1侧面剖视图；该图展示了阀体内部的细节。在支臂接头210中，过水件211左端的螺纹与支臂配合固定；过水件211与球头214固定以后，由衬套213和球头垫圈215在两个方向固定限位，由螺母212锁紧于阀体，如此过水件211连同球头214可以相对于阀体自由轴向旋转，且可以一定范围地轴向偏离，使安装和使用均具有较大的自由度。
阀体内部具有两个隔离的腔体，分别是进水腔101和出水腔102。进水腔101与来自支臂接头210的水路连通，同时通过上接头110其上顺流管口112的通孔连通了顺流管104。上接头110顶端具有环状凸缘111,该环状凸缘主要是使进水腔101与出水腔102以及逆流管103顶端隔离,同时当上盖109同时从上部将阀体密封固定时，也同时压紧环状凸缘111，从而将顺流管104和逆流管103与阀体妥善地固定不会向上脱出。
出水腔102实则位于逆流管103外侧与阀体之间，通过逆流管103壁上的通孔连通逆流管103内部，该出水腔103通过出水口202与外部连通，用于固定高位设备比如头部花洒。
在逆流管103和顺流管104的下端通过一下接头120固定且连通。该下接头120中央是插接与顺流管104的下顺流管口121，下顺流管口121外缘是连通逆流管103的下逆流管孔122。下顺流管口121和下逆流管孔122与切换件130连通，并且下逆流管孔122受切换件130控制通断。当下逆流管孔122受控阻塞时，来自顺流管104的水流唯有从切换件130流出，而不能通过逆流管103往上返回。若切换件130未阻塞下逆流管孔122，且其外部连接的低位设备关断，则来自顺流管104的水流可以通过逆流管103内壁返回，直达出水腔102，最终通过出水口202流出至高位设备。
图3是实施例1上面部分的剖视图，该图主要展示了上接头110固定顺、逆流管的细节。定位轴105横向将上接头110贯穿且两端伸出，限位于阀体100内的台阶，使三者不会从下方脱出。如此简单的装配，同时固定了顺、逆流管，免除了顺、逆流管上焊接辅助的安装结构比如螺纹件。
实施例二：
如图4所示，本发明实施例二部分侧面剖视图。与实施例一相比，顺流管104和逆流管103不再是相嵌套的形态，而是从同一个管道中用隔板106纵向隔离形成的形态；因此上接头110的上顺流管口112也是处于偏心的位置，为要妥善插接于顺流管104中，同时使进水腔101在阀体中与逆流管103相隔离。同样地，下接头120也与实施例一不同，下逆流管孔122不再环绕下顺流管口121，而是二者偏心分布，各自对应逆、顺流管。本实施例中，顺流管104和逆流管103可一体成型，如此更进一步减少了组装零件的数量和工序。
实施例三：
如图5所示，本发明实施例三部分剖视图。本例与实施例一类似，同样采用内外嵌套的顺、逆流管的形式；不同的是，逆流管104嵌套于顺流管103中；从而进水腔101就位于顺流管103外部、阀体100内；出水腔102就位于上接头110内。
实施例四：
如图6所示，本发明实施例四部分侧面剖视图。与实施例二相比，顺流管104和逆流管103同样是从同一个管道中用隔板106纵向隔离形成的形态；不同的是，上接头110的上逆流管口113处于偏心的位置，而插接于逆流管103中；相应地，进水腔101为环形，位于顺、逆流管外部；同时，出水腔102已位于上接头110内部。
以上所述，仅为本发明较佳实施例而已，故不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。
工业实用性
