    • PROBLEM TO BE SOLVED: To provide a fluid coupling which enables reliable detection of gasket insertion failure in a leak test when the failure occurs.SOLUTION: Annular seal protrusions 7 and 8, and annular protrusions 9 and 10 for preventing overtightening whose protrusion amounts are larger than those of the seal protrusions, are provided on the abutting end faces of respective coupling members 1 and 2. Communication paths 31 and 32, which makes the internal space Si communicate with external space So when both annular protrusions 9 and 10 for preventing overtightening are butted against each other, are formed on at least one of the annular protrusions 9 and 10 for preventing overtightening.
    • 要解决的问题:提供一种流体联轴器,当故障发生时,能够可靠地检测泄漏测试中的垫片插入故障。 解决方案:环形密封突起7和8以及用于防止突出量大于密封突起的突出量的环形突起9和10设置在各个联接构件1和2的邻接端面上。连通路径 31和32,其使得内部空间Si与外部空间连通。因此,当用于防止过度拧紧的两个环形突起9和10彼此抵靠时,形成在至少一个环形突起9和10上,以防止过度拧紧。 版权所有(C)2012,JPO&INPIT
