STAND FOR TESTING THE LEAKPROOFNESS OF WATER-PRESSURE COMMUNICATIONS

摘要

FIELD: fire-fighting. ^ SUBSTANCE: stand refers to the fire-fighting equipment, specifically to the constructions providing the feed of the fire extinguishing agent in area of fire in hose line. The contains an air feed line to the stand and a water level line in the gauge tube, and also contains five lines: the first line - line, containing a fire-engine of water communications with a stand by means of a flexible hose containing manometer for the water and a valve; the second line - a line for filling the stand and the pump with water from the inner water pipe through the valve and the back-pressure valve; the third line - a line for the water discharge from the stand through the valve; at that the first three lines are connected at the lower connecting box; the fourth line - an overflow line with a valve; the fifth - air inlet line to the stand with pressure through the reduction valve with manometer of the air inlet line through the valve and the return valve, at that the fourth and the fifth lines are connected at the upper connecting box which is connected to the lower connecting box by means of gauge tube. ^ EFFECT: increased effectiveness of fire suppression. ^ 1 dwg
