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. 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.Technical
