<p>PROBLEM TO BE SOLVED: To provide an automatic separation type piping coupling which feeds a gas such as helium in a gas container to a balloon automatically, and after that, separates the connection of the female coupling and the male coupling of a piping coupling so as to raise the balloon in the air securely and rapidly, and can show the place of refuge and the like to inhavitants by the balloon. SOLUTION: In this automatic separation type piping coupling, a piston chamber 29 communicating to the inside of a gas container 1 through a branch piping 42 from the container bulb 1; and a piston 14 slidable corresponding to the pressure of the piston chamber 29; are provided. While a sleeve 16 slidable integrally with the piston 14 while being energized by a spring 17 is provided, plural steel balls 19 which move freely between a circular groove 86 side provided at the inner diameter part of the sleeve 16, and a circular groove 77 side provided at the outer diameter part of the male main body 11, by the sliding operation of the sleeve 16, and can combine and separate the female main body 11 and the male main body 31, are provided.</p> |
