The glass ball closed sprinkler head is an automatic sprinkler head with a heat-sensitive element and its sealing component. The heat-sensitive element can operate in a predetermined temperature range, causing the heat-sensitive element and its sealing component to separate from the main body of the sprinkler head, and spray water according to the prescribed shape and amount of water within the prescribed protection area to extinguish the fire. Its performance is directly related to the start-up, fire-extinguishing and fire-control effects of the system.

Glass ball closed nozzle operating temperature and color:

The glass ball closed nozzle comes in 7 colors: orange, red, yellow, green, blue, purple and black. The different colors are to distinguish the breaking temperature of the glass balls. The use temperature range of the closed nozzle glass balls is different, so the colors are different.

The temperatures corresponding to different colors are: orange 57℃, red 68℃, yellow 79℃, green 93℃, blue 141℃, purple 182℃, black 227℃

Glass ball closed nozzle types:

There are three commonly used structural types of glass ball closed nozzles: A series, B series and C series. Among them, A series is a closed ordinary frame, that is, the nozzle is embedded; B series is a closed protruding hole, that is, the nozzle is protruding; C series is a closed direct-fire frame.

Glass ball closed nozzle specifications:

There are two types of glass ball closed nozzles: high pressure and medium pressure. The working pressure of high pressure water mist closed nozzles is above 3.5Mpa, and the working pressure of medium pressure water mist closed nozzles is between 1.2Mpa and 3.5Mpa. The following is the specific model parameter table:
