Abstract
The invention relates to a pressure-holding fire-extinguishing nozzle and a method for realizing pressure equilibrium in the fire-extinguishing nozzle. The pressure-holding fire-extinguishing nozzle is characterized in that: it includes a nozzle part and an adapter tube, and a pressure-holding device for stabilizing and equilibrizing nozzle pressure is arranged between the nozzle part and the adapter tube. Compared with existing automatic water spray fire-extinguishing systems and gas fire-extinguishing system nozzles, as the equipped pressure-holding device has pressure-reducing and pressure-holding effects, the pressure-holding fire-extinguishing nozzle provided by the invention can effectively reduce the excess pressure of the nozzle, so that the pressure of all nozzles in the system can be maintained within a certain range. By reducing the excess nozzle pressure, the fire-extinguishing media of the system can be sprayed uniformly and the problem of pressure waste does not exist, thus reaching the effects of saving fire-extinguishing media and improving the fire-extinguishing reliability of the system.
