空气泡沫枪

泡沫枪是消防人员的手提消防器材，可用管牙接口与消防水带接口相接，通过消防压力与泡沫液混合并吸入空气，产生空气泡沫。空气泡沫枪是主要由枪筒、手轮、枪体、球阀、吸液管和KY65管牙接口构成，用于扑救甲、乙、丙类液体火灾或喷射水用于扑救一般固体火灾。

二．工作原理

work principle

空气泡沫枪进水口端与消防水带连接，吸液管接口与吸液连接，吸液管另一端插入泡沫液桶内，当水流以0.7MPa压力通过水带进入枪内，经喷嘴喷出时，枪体内在水流的作用下形成负压，此时泡沫液通过吸液管吸入枪体内与水混合，当混合液由喷嘴射出时，由于射速再次形成负压，吸入大量空气与混合液混合，当经过枪筒使空气泡沫混合膨化，空气泡沫达到平衡后由枪筒喷出。

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.
