    • PROBLEM TO BE SOLVED: To provide a pipe joint for emergency releasing capable of preventing a plug from bolting out of a socket by the fluid pressure remaining between the socket and the plug when detaching the socket from the plug. SOLUTION: The inside of the socket 1 is partitioned into a front inside 4 and a rear inside 5 with a partition wall 3, and a fluid passage 6 opening to the front inside 4 and the rear inside 5 is formed. A cylindrical socket valve 8 is slidably fitted into the front inside 4. A valve hole 9 which radially communicates with the fluid passage 6 opening to the front inside 4 at the retracted position and advances and slips, is radially provided through on the peripheral wall of the socket valve 8. A plug fluid passage hole 30 radially communicating with the valve hole 9 of the socket valve 8 is radially provided through at the position where a lock ball 17 provided on the socket 1 engages with a lock groove 28 provided on the plug 2. A plug valve 34 which advances to close the plug fluid passage hole 30 and retracts to open it, is provided in the fluid passage 33 in the plug 2. COPYRIGHT: (C)2004,JPO
    • 要解决的问题:提供一种用于紧急释放的管接头,当将插座从插头上拆下时,能够通过留在插座和插头之间的流体压力来防止插头从插座中拔出。 解决方案:插座1的内部分隔成具有分隔壁3的前部内部4和后部内部5,并且形成通向前部内部4和后部内部5的流体通道6。 圆柱形插座阀8可滑动地装配在前部内部4.在缩回位置和前进滑动的通向前部内部4的流体通道6径向连通的阀孔9沿径向设置在 与插座阀8的阀孔9径向连通的插塞流体通道孔30径向设置在设置在插座1上的锁定球17与设置在插头上的锁定槽28接合的位置处 插塞2中的流体通道33中设置有用于封闭塞子流体通道孔30并缩回以将其打开的旋塞阀34。(C)2004,JPO
