The invention relates to a component of a gaseous fire suppression system. A concealed extendable nozzle for gaseous fire suppression systems is mounted on a distribution pipe of a gaseous fire suppression system. The nozzle consists of a body with discharge openings and a cap. A rod of a nipple is mounted inside the body of the nozzle. The nipple rod has a variable outside diameter: at one end, the rod narrows and ends in a connecting thread, whereas at the other end, the rod widens. Meanwhile, the body has an opening of variable diameter, which permits movement of the nipple rod inside the body; the body of the nozzle has a widening on the outside. A cap is fastened to the body of the nozzle, and this connection is tightly sealed by a washer. In another embodiment of the nozzle, the body has an opening of variable diameter, which permits movement of the nipple rod inside the body. A thread for connection to a distribution pipe of a fire suppression system is provided in the cap. At the opposite end from the cap, a protective cover is fastened to the body of the nozzle. The nozzle is fastened to the connecting thread of the nipple rod. The technical result of the claimed group of inventions is the even dispersal of a gaseous fire extinguishant inside a room. |
