The present invention provides a safety joint capable of preventing the outflow of hydrogen by instantaneously shutting off the hydrogen gas flow path at the initial stage of detachment of the plug (nozzle-side member) from the socket (filler-side member). In the pipe joints (100, 100-1, 100-2) that close the plug-side stop valve (5) and the socket-side stop valve (24) when the plug (10) is detached from the socket (20), cut off the socket-side stop valve ( 24) The mechanism includes a socket-side spring (23) that urges the socket-side valve core (25), a socket-side rod (22) connected to the socket-side valve core (25), and a socket-side rod (22) that supports (places) the socket-side rod ( 22) support members (26, 27, 28), the support members (26, 27, 28) move together with the plug (10) when the plug (10) is disengaged from the socket (20) and change to be unsupported (unloaded) Set) the state of the socket side lever (22). |
