A socket 4 is fitted through a metal ball 2 and a spring (coil spring) 3. For example, there are 16 balls 2 arranged at equal intervals on the circumference, and when the nipple 1 and the socket 4 are in a connected state (locked state), the balls 2 are sunk into the nipple 1 side (as shown in FIG. 3a). Now, when the lanyard 5 connected to the socket 4 is pulled in the direction of the arrow X, the socket 4 slides by a distance L and the ball 2 rises (as shown in Figure 3b). This is called the unlocked state. Further, when the socket 4 is pulled in the direction of the arrow X, the nipple 1 and the socket 4 are separated (FIG. 3c). In addition, 6 and 7 in the figure are circumferential hollow parts, and 8
is a ring that prevents the socket 4 from being pushed out by the coil spring 3.

で一旦蓄積されて一様に吹出す。 In a quick disconnect with such a structure, before flowing a cryogenic fluid (LNG, liquid oxygen, liquid nitrogen, liquid hydrogen, etc.) into the connector, a gas that does not liquefy or solidify at the liquid temperature is blown through the purge pipe 13. I'll keep it. Then, while gas is flowing from the purge pipe 13, the cryogenic fluid is flowed and transferred. After the transfer, the nipple 1 and the socket 4 are separated by pulling the lanyard 5 at a necessary time. Here, the gas from the purge pipe 13 continues to flow while the quick disconnect is lower than room temperature. In FIG. 1, the interval L between the cavities 7 is within the range in which the socket 4 slides in the )
Once accumulated, it is blown out uniformly.

However, by blowing gas that does not liquefy or solidify at the fluid temperature through the purge pipe 13 and uniformly blowing it out from the rectifier plates 11 and 12 before and after flowing the cryogenic fluid into the inside of the connect, water vapor and water in the atmosphere are removed. Prevents sticking due to air (nitrogen, oxygen) blowing,
It becomes possible to separate the nipple 1 and the socket 4 in the atmosphere at extremely low temperatures.
