water fire sprinkler is the part of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been reached.

Open orifice sprinklers are only used in water spray systems or deluge sprinklers systems. They are identical to the automatic sprinkler on which they are based, with the heat sensitive operating element removed.

Standard type ZST  fire sprinkler Purpose:

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 stand, sealant and glass ball.  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 ball 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.

Conseal type sprinkler Purpose

As the sprinkler can be hidden inside the ceiling, with matched cover color with the color of ceiling, which is not easy to be found while providing protection, it is widely adopted by place with luxurious decoration and beautiful ornament, or place with low ceiling due to the decoration, or place with thick population or frequency cargo transportation, or place where exposed sprinkler is easily touched.  For example, high class hotel, shop, recreation place and office building.

The sprinkler is composed of glass ball sprinkler, support ring, casing and cover.  The casing and the cover are welded with fusible alloy of low melting point. It is installed inside the protective district via ductwork, acting as a fire detector and auto sprinkler.  In case of fire inside the protective district, when the atmosphere temperature rises up and reaches the melting point of the fusible alloy, the cover will drop from the casing and expose the sprinkler.  When the temperature keeps rising and reaches the operating temperature of the glass ball, the glass ball will explode, the sealant will drop and the sprinkler will spray to the protective district for fire extinguishments subject to the preset shape of spraying.
