SPRINKLERS
There are two types of sprinklers - bulb type and solder type. Quartzoid bulb type sprinklers are available in a variety of attractive finishes that blend well with their surroundings. When In stand-by service, a small bubble in the fluid contained in the bulb compensates for normal temperature changes. When heated, the fluid in the bulb expands and shatters the bulb which allows water to be discharge. Solder type sprinklers employ a bell-shaped copper link whose two sections are joined by solders with a predetermined temperature rating. Heat absorbed by the link is conducted directly to the solder joint. When the solder melts, the link springs apart, releasing water that strikes the deflector.
