Sprinkler Introduction:

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.

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)

Pendent Sprinklers: Uesd Mainly, Where water pipeline, used for sprinklers in - stallation is concealed. The sprinkler is mounted in a I discharging spray hemispherically. 

Conventional Sprinkles: Used either in Upright or in Pendent Positions producing a spherical pattern with part of water sprayed towards the cell.

Upright Sprinkles: Used mainly where the water pipeline is exposed. Mounded only in Upright position discharging spray hemispherically.

Sidewall Sprinkles: Used mainly, where the pipeline run along the wall, sprinkles form out ward half parboiled pattern.

Declare:

Glass ball closed sprinkle nozzle is the most key components of automatic sprinkler system, used to detect the instrument of fire element,And to control fire and extinguish firethrough the automatic water spray device. Apply to work environment temperature less than 4 ℃, and is not higher than 70 ℃ in light of the danger level buildings as wet system to fight fire water of the hotel, department stores, restaurants, entertainment, warehouse, hospitals, factories, the airport and the basement automatic sprinkler system such as the pipe network.

.Principle of operation:

This series of ball sprinkler head working principle is filled with high thermal expansion coefficient of organic solution of the glass ball as a heat sensitive components. At normal temperature, and the glass ball shell we can withstand the support, ensure wards of the seal. When the fire breaks out temperature, glass ball inside the organic solution happen and generates a lot of thermal pressure inside, until the glass ball shell happen broken, and open water spray nozzle.

.Structure characteristics:

This series of ball sprinkle nozzle is made of copper alloy frame, glass ball, seal, glass ball seat, tight set screws and splash water dish wait for assembly and into. Compact structure, shape exquisite and beautiful

3.1,Nozzle framework USES the high strength copper alloy precision forging, high strength,corrosion resistance.

3.2, Temperature temperature sensing elements (ball) with high quality products at home and abroad, glass ball high strength, reliable, and reaction speed.

3.3, Temperature temperature sensing elements (ball) with high quality products at home and abroad, glass ball high strength, reliable, and reaction speed.
