fire sprinkler

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

and structures with light fire danger, medium fire danger and heavy fire danger, such as workshop, warehouse,

hotel, shop, recreational place, hospital, cinema, office building and garage.

2. 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 and the 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.
