fire sprinkler nozzle
The gas fire extinguishing nozzle is one of the important components of the gas fire extinguishing system. Its function is to confirm that the fire extinguishing agent is ejected in a specific jet form, prompting the fire extinguishing agent to quickly vaporize and reach the fire extinguishing concentration in the protected space. Its fire extinguishing efficiency is high and the fire extinguishing speed is fast.
Gas fire sprinkler model:
Commonly used models of gas fire sprinklers include: DN15, DN20, DN25, DN32, DN40, DN50, etc., which can meet basic application needs. In addition, Lanzhong Electromechanical can also be customized, and only needs to provide relevant parameters of the nozzle. The following is a selection table for conventional gas fire sprinklers:
