图21表示具有固定活门的接头的剖视图。 
附图表示一种快速接头100，该快速接头100包括第一元件50和第二元件60。 
在外部，第一元件50(图1-4)主要由外部套筒1和连接器2形成。外部套筒1设有挂钩系统，该挂钩系统具有三个螺旋凹槽3、和用于安全装置的三个前部阀座4。连接器2具有用于用户接口(管子、控制单元、等等)的两个螺纹出口25。 
在内部，第一元件50主要由彼此未对准的两个阀接头16、活门6及导向销7形成。 
阀接头16中的一个插入到压力管线9中，并且另一个插入到排出管线10中，并且当接头脱开时起关闭流动的作用，而当接头联接时使接头畅通。 
借助于密封件8，活门6关闭轴向孔61，该轴向孔61借助于与轴线横交的通道91放置成与压力管线9连通(图4和18)。 
导向销7允许在挂钩步骤期间与第二元件60对中。 
在外部，第二元件60(图5-8)主要由挂钩环形螺母70、安全环形螺母11、及连接器12形成。挂钩环形螺母70具有三个径向固定销13，这三个径向固定销13通过接合螺旋凹槽3和由于环形螺母70的转动，允许第二元件60与第一元件50相联接。 
三个安全销14固定在安全环形螺母11中，与环形螺母11本身一起轴向地滑动。安全环形螺母11由压缩弹簧15推动成抵靠挂钩环形螺母70。 
在内部，第二元件60主要由彼此未对准的两个阀接头17、转向阀18及用于导向销7的阀座19形成。 
阀接头17中的一个插入到压力管线20中，并且另一个插入到排 出管线21中，并且当接头脱开时起关闭流动的作用，而当接头联接时使接头畅通。 
转向阀18允许当接头脱开时压力管线20与排出管线21相连通，并且当接头联接时关闭连通。 
连接器12在其一个端部处具有用于用户接口(管子等等)的两个螺纹出口122，而连接到第一元件50上的内部部分具有两个管线20和21成为同轴的特性(图16和20)，并且通过球形装置16，允许连接到管子上的连接器12的部分12′相对于外部套筒1的转动(在图16中，部分12′表示成相对于图8转动)。值得注意的是，所述转动部分12′也可以或可选择地设有在连接器2中的第一元件50。 
阀座19容纳第一元件50的导向销7，因而允许在挂钩步骤期间与第一元件50对中。 
为了联接接头(图9-12)，第一元件50的外部套筒1插入到第二元件的挂钩环形螺母70中(图9)，并且在挂钩销13进入螺旋凹槽3的同时，通过转动两个部分直到导向销7进入其阀座19中，进行对中。在这时，通过转动挂钩环形螺母70将第一元件50驱动到第二元件60中(图10-11)。 
通过触及安全销14，外部套筒1的前部部分推动安全环形螺母11，因而允许继续挂钩环形螺母70的转动，直到挂钩销13到达行程的端部(螺旋凹槽的端部)。在这个位置中，完成联接，并且由于压缩弹簧15，将安全销14推动到在外部套筒1上前部布置的阀座4中，因而防止挂钩环形螺母70相对于外部套筒1转动，并因而避免接头偶然脱钩(图12)。 
第一元件50用第二元件60阻塞，而也可放置在第一元件50上的突出元件60的同轴转动连接器12，凭借球形装置16可以转动(图12)，因而避免柔性管子的可能扭曲。 
为了脱开接头100，安全环形螺母11需要后退，从而使安全销14与它们的阀座4脱开(图13)，并因而相对于接头在相反的方向上转动(图14)。 
另一方面，外部套筒1的前部阀座4具有肩部41(图1)，从而销14在释放转动期间可能不离开，而另一方面，它们具有倾斜平面42，以允许销14在挂钩转动期间离开。 
第二元件60的转向装置包括转向阀18，该转向阀18当接头脱开时借助于通道31和32将压力管线20放置成与排出管线21相连通，并且当联接接头时关闭连通。 
当接头脱开时(图9)，来自压力管线20的流动，由于流体静推力，向前推动阀18，因而在阀18的腔室34中产生通路(图9-11，具体地见图11的放大图)，以穿过所述腔室34上游和下游的通道31和32流入到排出管线21中。这种流体再循环防止在压力管线20中产生压力。当联接时，阀18与第一元件50的活门6相接触(图10)，并且为了关闭被推动成抵靠其阀座33。 
在阀18仍然敞开的情况下(图11)，第一元件的阀，即密封套筒22，首先被打开，因而允许在第一元件50中的可能压力被排放到第二元件60中，并因此阀18被打开以排放到排出管线中。当接头被完全联接时，活门6将阀18向密封阀座33推动，因而关闭在压力管线20与排出管线21之间的连通(在图12中的放大图)。 
第一元件50的活门6具有比阀18的直径d2大的直径d1，并因此活门6的流体静推力截面也比阀18的流体静推力截面大。作为这种概念的结果，压力在活门6一侧产生较大力，该力将阀18向阀座33推动，因而保证密封。 
可选择地，如图21所示，可以包括固定活门6，该固定活门6在全部情况下都将转向阀18推到其阀座33中，可能具有精确配合腔室34的阀18的直径。 
接头的脱钩包括阀18的一系列位置，这些位置与以上提到的那些位置反向。
