Sprinkler is an important part of wet-type auto spraying system. It is usually installed inside the building and structures with

The sprinkler is composed of sprinkler frame, sealant and glass bulb. It is to be installed in the protective district via ductwork,
acting as a fire detector and auto sprayer. In case of fire inside the protective district, the atmosphere temperature rises up
andthe liquid inside the glass bulb expands after being heated and explodes after reaching the operating temperature
of the glass ball. The sealant drops and the sprinkler sprays to the protective district for fire extinguishments
subject to the preset shape of spraying.
2.Installation,Usage and Maintenance:
During installation, should pay attention not to damage the bulb to avoid affect the thermal performance. In the
process of wrench and twist, do not use spanner to wrench the supporting arm to deformation and affect the
sealing performance (note: the bulb temperature can be chosen according to the needs of users)
