摘要： A dry break coupling for joining together opposing passageways includes a male member and a female member, each of which includes a resiliently deformable rubber flap with cross-hair slits positioned to engage each other as the male and female members are moved axially toward their coupled position. Each of the male and female members also is provided with a normally closed but resiliently openable rubber septum position on the opposite side of its rubber flap from the engagement end of the respective members. The male member is provided with a blunt cannula which is fixed and a moveable carrier supporting the rubber septum. The female member is provided with an axially moveable support for the rubber flap and a fixed support for the rubber septum. As the male member and the female member move to the fully coupled position, the peripheral portions of the abutting rubber flaps are moved axially with the female carrier member while the central portions are prevented from moving by the fixed septum support with the result that the slits of the rubber flaps are pulled open thereby permitting the respective septums to engage each other. Further movement of the male and female members toward one another causes the moveable support for the male member septum to be retracted with the result that the cannula is urged through the resiliently openable abutting septums to open the passageway to the flow of fluid.
摘要翻译：用于将相对通道连接在一起的干式断裂联接件包括阳构件和阴构件，每个构件包括可弹性变形的橡胶翼片，其中十字头狭缝被定位成当阳构件和阴构件轴向移动到其联接位置时彼此接合。阳构件和阴构件中的每一个还设置有与其各个构件的接合端在其橡胶翼的相对侧上的常闭但可弹性打开的橡胶隔膜位置。阳构件设置有固定的钝头套管和支撑橡胶隔垫的可移动的支架。阴构件设置有用于橡胶翼的可轴向移动的支撑件和用于橡胶隔垫的固定支撑件。当阳构件和阴构件移动到完全联接位置时，抵靠的橡胶翼片的周边部分与阴承载构件一起移动，同时防止中心部分被固定隔垫支撑件移动，结果是狭缝的橡胶翼片被拉开，从而允许相应的隔膜彼此接合。阳和阴构件朝向彼此的进一步运动导致阳构件隔膜的可移动支撑件缩回，结果是套管被推动穿过可弹性打开的邻接隔膜以将通道打开到流体流动。
