Coupling element with a shutter valve, and a coupling incorporating such an element
Abstract:
The invention concerns the female or male member (3) of a connection (1) that can be connected with a corresponding male or female connection member (5) and includes a pusher (33) and a stop valve (35) capable of sliding axially relative to the pusher (33) for coupling to the member (3). The member (3) further includes at least one seal (34) mounted on a first part (35) selected from the pusher and the valve and capable of sealing interaction with a first portion (331) of the second part (33) selected from the pusher and the valve in an uncoupled configuration of the member (3). In the coupled configuration of the member (3), a second portion (333) of the second part (33), defining a seal (34) protection portion (333), is radially provided between the seal (34) and a main fluid flow line (V) in the member (3). The portions (331, 333) have different radial dimensions so that the radial thickness available for the seal (34) in the coupled configuration is higher than the radial configuration available for the seal (34) in the uncoupled configuration. The portions (331, 333) are connected to each other by connection tabs (338) having a constant cross-section.
Abstract(Chinese):

本发明涉及可与相应的公或母连接构件（5）连接的连接件（1）的阴或阳构件（3），并且包括推动器（33）和能够轴向滑动的截止阀（35） 相对于用于联接到构件（3）的推动器（33）。 构件（3）还包括安装在从推动器和阀选择的第一部分（35）上的至少一个密封件（34），并且能够与第二部件（33）的第一部分（331） 所述推动器和所述构件（3）的脱离构造中的所述阀。 在构件（3）的联接构造中，限定密封件（34）保护部分（333）的第二部分（33）的第二部分（333）径向地设置在密封件（34）和主流体 （3）中的流动线（V）。 部分（331,333）具有不同的径向尺寸，使得在联接构造中可用于密封件（34）的径向厚度高于可用于处于非耦合配置中的密封件（34）的径向构型。 部分（331,333）通过具有恒定横截面的连接片（338）彼此连接。
