摘要： A pipe coupling member for high-pressure fluid such as liquefied hydrogen includes a seal ring having a highly effective sealing function to prevent leakage of the fluid. The seal ring (72) is set in a seal ring setting space (39) defined by a second radial surface (36) and a seal ring setting surface (38) of a first tubular member (20), a forward end surface of a second tubular member (22), and the outer peripheral surface of a valve seat member(24). A forward end portion of the second tubular member (22) is provided with a communication hole (84) radially penetrating the forward end portion. The pressure of the high-pressure fluid on the downstream side of a valve seat surface (52) causes a fluid path in the second tubular member to be communicated with the sealing ring setting space (39) via the communication hole (84) and via a gap between the seal ring setting surface (38) and the outer peripheral surface of the forward end portion of the second tubular member.

摘要： ABSTRACT: A pipe coupling capable of being safely connected and disconnected. The pipe coupling has a tubular housing (16), a first locking member (18), a pressing member (24), a valve member (30), and a second locking member (50) provided between the valve member (30) and the pressing member (24). When the housing is communicated with a fluid source with the pressing member (24) placed in a standby position ( Figs. 1 to 4 ), the second locking member is displaced by the valve member, which is displaced toward an open position by fluid pressure. In this process, the second locking member engages with the pressing member (24) before the valve member reaches the open position ( Fig. 2 ), thereby preventing the valve member from reaching the open position and, at the same time, preventing the pressing member from being displaced to a pressing position. When the housing is communicated with the fluid source with the pressing member (24) placed in the pressing position ( Fig. 4 ), the second locking member does not engage with the pressing member and allows the valve member to be displaced to the open position.
