APPARATUS FOR MEASURING PRESSURE WITHSTANDING EXPANSION OF GAS CONTAINER

PROBLEM TO BE SOLVED: To attach and detach a nozzle to a pipe opening of a gas container by a one touch operation, and transfer the gas container efficiently automatically, by engaging a locking ball to a lower opening edge of the pipe opening and holding and suspending the gas container at the side of a lower face of a lid body. SOLUTION: A lower end part of a nozzle body 11 having a biasing shaft 15 raised is inserted to a container pipe opening 101. Then the biasing shaft 15 is lowered to project a locking ball 13 from a fit hole 12 to be engaged with a lower opening edge 103 of the pipe opening 101. Accordingly the nozzle body 11 is prevented from slipping off. The nozzle body 11 is integrally mounted to a gas container 100 and the gas container 100 is held and suspended via the nozzle body 11 at the side of a lower face of a lid body 6. The gas container 100 is moved to a measurement position by moving the lid body 6 parallel, up and down at a suitable time, soaked and suspended in a water jacket by lowering the lid body 6. A high pressure water is pressed into the gas container 100. A pressure withstanding expansion is measured in this manner. After the measurement, the gas container 100 is transferred by moving the lid body 6 up, parallel.
