用于连接两个传输压力气体的管道的快速接头
摘要：
本发明涉及一种快速接头，其包括阳元件(3)和阴元件(2)。保持闩锁(20)用于将插栓(5)保持在所述阴元件(7)中并能够在第一位置和第二位置之间移动，在所述第一位置，所述闩锁(20)能够将所述插栓(5)保持在所述阴元件(7)中的第一深度从而所述插栓以密封方式连接至所述阴元件，在所述第二位置，所述闩锁(20)适于将所述插栓(5)保持至小于所述第一深度的第二深度。所述闩锁(20)构造为：当所述插栓处于第二深度时，所述闩锁至少部分地通过用于使下游管道通流的通道(4、17、26、34)中的正压力朝所述第二位置回复。在本发明的变型实施方式中，所述接头包括适于由所述闩锁保持的配接件。
摘要（英）：

The invention relates to a quick coupling comprising a male connector (3) and a female element (2). The invention also comprises a retaining bolt (20) which is used to retain the connector (5) in thefemale element (7) and which can move between a first position, in which the bolt (20) can retain the connector (5) at a first depth inside the female element (7) such that it is connected thereto bymeans of a tight joint, and a second position, in which the bolt (20) can retain the male connector (5) at a second depth which is smaller than the first depth. The bolt (20) is configured such that it is at least partially returned (F3) to the second position as a result over an overpressure in a downstream line purge passage (4, 17, 26, 34), said purge passage (4, 17, 26, 34) being open when theconnector is at the second depth. In one embodiment of the invention, the coupling comprises an adapter which can be retained by the bolt.
