Brass Quick Response Fire Sprinkler Heads , ESFR Water Sprinkler
For Fire Protection , Fire Safety Sprinklers
Fire Sprinkler Heads Description:
Main units of the ESFR series quick response sprinkler are glass bulb, seal and sprinkler. The glass bulb consists of an
accurately controlled amount of special fluid hermetically sealed
inside a precisely manufactured glass capsule. This glass bulb is
specially constructed to provide fast thermal response. At normal
temperatures, the glass bulb contains the fluid in both the liquid
and vapor phases. The vapor phase can be seen as a small bubble. As
heat is applied, the liquid expands, forcing the bubble smaller and
smaller as the liquid pressure increases. Continued heating forces
the liquid to push out against the bulb, causing the glass to
shatter, opening the waterway and allowing the deflector to
distribute the discharging water. In the action of quick response
and water flow rate, the sprinkler can put out the high risk of
fire at the early period.
Application:
Quick response sprinklers are used in fixed fire protection
systems: Wet, Dry, Deluge or Preaction such as huge theatres, halls
and convention center. Quick response sprinklers and standard
response sprinklers should not be intermixed.
