WATER CURTAIN GENERATOR FOR DOOR

摘要

PURPOSE: A water curtain generator for a door is provided to prevent the damage to a door due to flames and to restrain the generation of toxic gas. CONSTITUTION: A water curtain generator for a door includes a header(11) and multiple nozzle pipes(12). The cylindrical header is installed to be fixed to the upper front of the door, is connected to an external water pipe, and is supplied with water. The nozzle pipe is downwardly extended from the header, and inclines rearwards at a certain angle from an axis vertical to the ground so that the water can spray on the outer surface of the door through the nozzle pipe. On a front view, intervals among the nozzles become wider from the top to the bottom.
