The invention concerns a safety device for a dispensing installation connected to a pressurised fluid supply network, in particular a water or gas supply network. The invention is characterised in that it comprises a fluid circuit including at least an electromagnetic valve (EV) and two pressure controllers, a high pressure controller (P¿1?) and a low pressure controller (P¿2?) respectively, and a logic electrical circuit comprising control means for opening said electromagnetic valve if the pressure downstream of the electromagnetic valve suddenly drops and for closing it if it is within the range defined by the two pressure controllers (P¿1?, P¿2?).
Dispositif de sécurité pour une installation de distribution reliée à un réseau d'alimentation de fluide sous pression, notamment un réseau d'alimentation d'eau ou de gaz. Selon l'invention, le dispositif comporte un circuit fluidique incluant au moins une électrovanne (EV) et deux pressostats, respectivement un pressostat haut (P1) et un pressostat bas (P2), et un circuit électrique logique comprenant des moyens de commande pour ouvrir ladite électrovanne si la pression en aval de l'électrovanne chute brusquement et pour la fermer si elle entre dans l'intervalle défini par les deux pressostats (P1, P2).
