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. The technical result is the even dispersal of a gaseous fire extinguishant inside a room.
A concealed extending sprinkler for gas fire suppression systems, mounted on a distributive pipe of the gas fire suppression system and comprising a sprinkler case with discharge outlets and a cover, characterized in that a nipple rod is installed in the sprinkler case, a groove in the sprinkler case and in a nipple rod case is designed for O-ring sealing, the nipple rod is of variable OD (outer diameter), on the one side the rod is tapered and ended with a connection thread, on another side it is extended, wherein in its turn the case has an opening of variable diameter providing moving the nipple rod inside the nipple rod case, the sprinkler case is extended outside, the cover is secured to the sprinkler case, connection tightness between the cover and the sprinkler case is provided by a sealing gasket.
