SECURITY SYSTEM FOR CAS CYLINDERS

摘要

Novelty: a security system incorporated inside a gas cylinder is disclosed. Constitution: a sealing elastic portion 1 and a lamella 2 both interconnected and adapted to the gas cylinder 4 by anchoring of the two ends of the lamella at the walls of the gas cylinder 5 or at the internal peripheral step 7 or peripheral recesses provided. Function mode: the perforation blade 6 of the combustion head pierces the cylinder, presses the lamella along with the elastic portion which, both, step backwards, allowing the gas to escape. In case that -for whatever reason- the combustion head unscrews, then, owing to the return force, the lamella returns to its initial position and blocks the hole of the cylinder gas the leakage of which is thus hindered. Advantages: efficient security of gas cylinders with use of simple easily-assembled accessories; least economic burdening of the final product.
