摘要： A leak testing device to be positioned between two adjacent conduits comprises a generally cylindrical body defining a recess therethrough and including first and second end portions for cooperating with the respective end portions of two adjacent conduits. The body includes an opening between the first and second end portions. A sealing door is provided to be positioned in the opening. A diaphragm member including a through hole is provided to be positioned within the body. A valve is operably connected to the diaphragm member for selectively opening or closing the through hole to thereby permit or restrict the flow of a fluid between the two conduits. The opening in the body receives the diaphragm member when leak-testing a conduit, or the sealing door when connecting the two conduits in a fluid communication.
摘要翻译：定位在两个相邻导管之间的泄漏测试装置包括大致圆柱形主体，其限定穿过其中的凹部，并且包括用于与两个相邻导管的相应端部配合的第一和第二端部。主体包括在第一和第二端部之间的开口。设置密封门以定位在开口中。设置有包括通孔的隔膜构件以定位在主体内。阀可操作地连接到隔膜构件，用于选择性地打开或关闭通孔，从而允许或限制两个管道之间的流体流动。当在流体连通时连接两个管道时，在泄漏测试导管或密封门时，主体中的开口接收隔膜构件。
