<p>Disclosed is a device for controlling the descent of a sprinkler head deflector that is installed on a ceiling to sprinkle a fire-extinguishing agent in all directions when a fire breaks out, in which the device enables the deflector to descend steadily when the deflector descends at the outbreak of fire, and prevents a decrease in flow rate that is caused by flow passage resistance when a fire-extinguishing agent is sprinkled. To this end, a guide (30) fixed to a holder (14) comprises: two or more necks (31) placed on a flow passage (11a) of a body (11); and a latch (32) which is provided on the outer side of the necks (31) and is caught on a stepped projection (11b) of the body (11) so that the guide is fixed to the holder (14) using a fixing means.</p> |
