二．工作原理
work principle
空氣泡沫槍進水口端與消防水帶連接，吸液管接口與吸液連接，吸液管另一端插入泡沫液桶內，當水流以0.7MPa壓力通過水帶進入槍內，經噴嘴噴出時，槍體內在水流的作用下形成負壓，此時泡沫液通過吸液管吸入槍體內與水混合，當混合液由噴嘴射出時，由于射速再次形成負壓，吸入大量空氣與混合液混合，當經過槍筒使空氣泡沫混合膨化，空氣泡沫達到平衡后由槍筒噴出。
foam fire branch inlet end and the fire hose connection, to absorb fluid pipe interface and absorb fluid connection, to absorb fluid pipe the other end into the liquid foam inside bucket, with 0.7 MPa pressure when water flow through the water into the gun within the nozzle jet, the gun in the role of water in the body formed under negative pressure, the liquid foam at this time by smoking gun body in liquid pipe is mixed with water, and when the mixture by injection nozzle, because again firing rate forming negative pressure, and a lot of air inhaled with the mixture mixing, when after air bubble mixing barrel expanded, and the air bubble to balance out the barrel.
