Abstract

The invention is an emergency closing system (100) for drainage pipes (T), comprising: a shutter balloon (200) inserted and constrained inside a pipe (T) and normally in a totally or partially deflated configuration; a compressed air tank (300); a compressed air supply line (400) connected to said tank (300); a compressed air outlet line (500) connecting said tank (300) to said shutter balloon (200); a solenoid valve (510) mounted on said outlet line (500) and normally closed; an air valve (520) mounted on said outlet line (500) and normally closed; an ON/OFF control (600) for opening/closing said solenoid valve (510), wherein said control (600), when activated, opens said solenoid valve (510), with said air valve (520) closed, in such a way that the compressed air inflates said shutter balloon (200), which occludes said pipe (T).
