The thermal open joint is a sprinkler set under the condition of obstacles under the ceiling. By separating the functions of the sensing part and the spraying part of the closed sprinkler, the fire can be effectively sensed and extinguished even when there are obstacles near the ceiling.
The quality of the sprinkler bulb fully complies with the Chinese national standard GB18428-2010. The diameter of the sprinkler bulb is 3mm, and the deviation from the nominal diameter will not exceed ± 0.1mm; Its length is 23mm and the deviation from the nominal length will not exceed 0.5mm.
Dry pendent sprinkler is specially designed for those sprinklers and connection pipes which may be frozen at low temperatures or those sprinkler fire extinguishing systems where seasonal evacuation is required.
