1. What is Fire Sprinkler?
It is a nozzle that in the case of heat, according to the predetermined temperature range to start their own, or start by the control device according to the fire signal, then sprinkled water according to the designed shape and flow.
At the top of the nozzle, make sure the water can be sprinkled into a predetermined sprinkler shape.
Refers to the support arm of the nozzle and its connecting part.
4. Heat sensitive components
The components which capable of operating the fire sprinkler at a predetermined temperature.
5. Nominal Diameter
The nominal size if the sprinkler water outlet which according to the size of the flow.
6. Release mechanism
The mechanism consists of heat sensitive components, seals and other related parts. It is the part, when the sprinkler starts, can automatically out of the sprinkler body.
7. Static operating temperature
In an experimental setting, heating according to the provision conditions, the temperature which the thermal sensitive components action after heating.
8. Nominal action temperature
Indicate the nominal operating temperature of the closed sprinkler in different temperature range under different environmental conditions.
After the sprinkler is operated, the parts of the release mechanism, or the fragments of the thermal element remain in the nozzle frame or the deflector and so on, which will obviously affect the nozzle to sprinkled according to the designed shape for more than 1 min.
