Supply device for automatic fire extinguishing system for protection against small risks

摘要

The feed is for an automatic fire-extinguisher using water, and incorporating a mobile water tank (1), supplied with compressed air by a compressor (4) with pressure gauge (6). At the outlet from the tank is a throttle (14), generating a pressure drop and thus regulating the time for which the system operates. This throttle can be formed by a small calibrated aperture (14) in the end of a nozzle (16) fixed at the tank outlet. The nozzle in turn, can be fixed to a detachable union, connecting to a distribution pipe network (20).
