Cover assembly for a concealed sprinkler head |
摘要 |
A concealed sprinkler head is mounted above the ceiling of a fire protected zone. The sprinkler head includes a housing within which a valve and other operative parts are contained. A decorative cover plate is secured to the housing to conceal the sprinkler head within the ceiling so that none of the operative parts is visible. The cover assembly includes a thin metallic cover plate made of a heat conductive material such as copper, and a metallic skirt including a cylindrical wall threaded on the housing, an annular flange extending outwardly from one end of the cylindrical wall, and a plurality of tabs extending downwardly from the flange. A plurality of heat insulative elements are disposed between the tabs and the cover plate. A metallic layer is attached to the lower surface of each of the insulative elements. A layer of fusible material is disposed between the metallic layer and the cover plate to secure each of the insulative elements to the cover plate through the metallic layer.
