The principle of work for DCP system: Releasing the high pressured Nitrogen from Nitrogen Cylinder to Reduction Valve and decompresses the pressure to the work pressure, then transport them into Powder Tank, amount of them are transported to the bottom of the tank to relax the powder. Along with the tank’s contenting pressure update, some powders are transfer to the discharge pipe and arrive at the valve bellowing the powder monitor / powder gun or powder nozzle along with the pressured Nitrogen, when the pressure in the valve arrives at the rated pressure (or the pressure gauge on the tank indicate 1.5~1.6MPa), open the valve (or the breakable diaphragm breaking auto.), then the pressure energy are translated to speed energy, high speed powder spray out from monitor (gun or nozzle ), shot at the fire, incise the flame, destroy the burning chain, then stifle the fire quickly.
