Retention valve which controls the emptying of cylinders with liquid petroleum gas

摘要

To avoid waste of material and costs originated by retention valves that control the flow of liquid petroleum gas (GLP), wrongly assembled, lower the manufacturing costs, eliminate the potential risks in the security of the valve originated by the user's manipulation when disassembling and reassembling the same, and solving the problems related with the inner adjustment of some parts and the vibrations of the whole, there has been developed a connection rod POL (12) that eliminates the rod's end POL as an independent part by merging both parts in one single part, reducing significantly the normal vibration of the whole. The rod POL (12) includes an end (19) which consists in a concentric circular ring (20) with a plurality of rectangular cuts (21), preferably four and arranged orthogonally, partially surrounding the spring (10), so when the action of the fluid moves the rod POL (12), the ring (20) moves towards the end of the mechanized region (11).
