Tap for gas container comprises valve activated by plastic lever which melts at pre-specified temperature to push rod which puts valve in closed position on seat

摘要

The gas tank tap comprises a valve (8) able to take a closed position where it rests on a seat (9) and an open position, not in contact with the seat. The valve is activated by a plastic lever (5), rotating around a spindle (6) and operating a rod (7), which melts at a pre-specified temperature at which it is required that the valve is in the closed position. When the lever has melted the valve is put into the closed position.
