When it is necessary to raise the balloon 5 in the event of an earthquake or disaster, the flow path of the container valve 2 screwed to the gas container 1 is automatically opened by remote control. When the container valve 2 is opened, high-pressure (for example, 120 kgf / cm 2 ) compressed gas in the gas container 1 flows into the coupled female joint 10 and male joint 30.

てくる。The valve 37 in the male joint 30 has a predetermined pressure or more due to the high-pressure compressed gas that has flowed in. Therefore, the spring 38 is compressed, the valve 37 is automatically opened, and the compressed gas passes through the flexible hose 6. After that, the balloon 5 is supplied into the balloon 5, and the balloon 5 starts to expand. With the inflation of the balloon 5, the sealing pressure in the gas container 1 is reduced.

Is free in the radial direction, the steel ball 15 is provided on the distal end outer cylindrical portion 77 of the male main body 31 by the forward movement of the cylindrical slider 21 which has been retracted through the spring 20 into the female main body 11. Floating from a certain V-shaped annular groove 78, the connection with the female joint 10 is released.

実に然も安価にバルーンを空に上げることができる。As described above, if the automatic separation type pipe joint of the present invention described above is used as a pipe joint for filling a balloon with gas from a gas container, the joint can be manually operated when an earthquake or disaster suddenly occurs. Helium gas can be supplied to the balloon simply by opening the container valve by automatic remote control without separating the part, and when the internal pressure reaches a predetermined pressure due to balloon inflation, the valve in the male joint automatically closes At the same time, the female joint and the male joint can be automatically separated, and the balloon can be emptied reliably and inexpensively.
