Dry Pendant Type Side Wall Sprinkler Head

摘要

The present invention relates to a dry pendent type sidewall sprinkler head installed on a wall surface of a building to spray firewater upon a fire to control the fire in an early stage and an objective of the present invention is to improve a structure of the dry pendent type sidewall sprinkler head to fundamentally solve a phenomenon that a front deflector is locked to a locking step formed at an outlet of a frame when being separated from the frame by the occurrence of the fire. To this end, according to the present invention, the dry pendent type sidewall sprinkler head comprises: a dry pendent (10) connected to a branch pipe (90) and including a flow path opening/closing means (20) closing a position connected to the branch pipe to form space therein; the frame (30) coupled to one end of the dry pendent (10) and having an opened outlet; a deflector (60) including a side-directional deflector (50) fixed to the upper part of the frame (30) to suppress that the firewater is scattered to an upper side and the front deflector (40) installed in the frame (30) to be withdrawn, having a flange (41) formed at one end, and having a plurality of upwardly bent parts (44) formed at the other end to radially form a spray space (43); a heat collector (70) installed on the outlet side of the frame (30) to allow the front deflector (40) to be received in the frame (30); and a withdrawal means (80) pushing the front deflector (40) to the outside of the frame (30) upon separation of the heat collector (70) while being pressed and installed in the frame (30).
