 Execution standard: GB25202-2010

空气泡沫枪是一种能产生和喷射空气泡沫，用以扑救中型油类火灾的比较轻便的消防器材。

foam fire branchis a kind of can produce and injection air bubble to save the comparison of the medium oil fire light fire equipment.

空气泡沫枪由喷嘴、启闭柄、手轮，枪筒、吸液管、密封圈、吸液管接头、枪体、管牙接口等组成。喷嘴是用以控制流量和产生负压，启闭柄是空气泡沫枪液流开关和吸液开关，手轮用来控制泡沫枪喷射方向，枪筒用以调节空气泡沫膨化的动态平衡，吸液管用以吸取泡沫液，密封圈用以密封，吸液管接头用以的吸液管连接，枪体是空气泡沫枪的支座，管牙接口用以与消防水带连接。

foam fire branch by spray nozzle, handles, opening and closing the handwheel, barrel, absorb fluid pipe, sealing ring, to absorb fluid tube fittings, of gun, tube tooth interface etc. The nozzle to control the flow and is produced negative pressure, open the handle is air foam gun liquid flow switch and absorb fluid switch, the handwheel is used to control the foam spray gun direction, barrel to adjust air bubble expanded the dynamic balance, absorb fluid work to absorb liquid foam, sealing ring to seal, absorb fluid pipe joint to absorb fluid of tube connects, of gun is  foam fire branch bearing, the tooth interface to the fire hose connection with.

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.

三、    用户须知

user guidelines

1、          空气泡沫枪应配用3%-6%的泡沫液

2、          喷射时，应使泡沫向顺风方向喷射，避免测风和逆风喷射

3、          在不采用吸液管吸取泡沫时，消防水泵上需配备泡沫比例混合器，以便按规定比例输送泡沫混合液

4、          空气泡沫枪的工作压力是指泡沫枪进水口端的水流压力

5、          空气泡沫枪必须经常检查并保持枪体、手轮、枪筒、喷嘴、管牙接口、密封件的完整好用

6、          尽量避免磕碰摔打，以免损坏或影响使用，造成不必要的损失

7、          使用完毕，要将各部位清洗干净，置于阴凉干燥的地方妥善保管

8、          平时不得与酸碱等化学物质混放，远离热源，以防各橡胶部件和高压聚乙稀件老化变形

9、          运输的贮存中均应避免重压、撞击、雨淋、曝晒和接触腐蚀性化学物质

10、       产品保质期1年，因安装或使用不当等引起和质量问题或经济损失，不属于本公司责任范围

1, foam fire branch should be 6% of the bubble with liquid

2, injection, should make foam injection to a direction, avoid the wind and against the wind injection

3, in not using liquid pipe absorption from bubble, fire pump on the need to have foam proportion mixer, so as to press formulary scale conveying foam mixture

4, foam fire branch pressure of work is to point to the inlet water bubble gun pressure

5, foam fire branch must often check and maintain of gun, the handwheel, barrel, nozzle, tube and sealing pieces of complete tooth interface works better

6, try to avoid knock against throw, lest damage or affected use, cause needless loss

7, after use, to the place clean, in a cool, dry place for safe keeping

8, at ordinary times may not soda acid and chemical readjusting, far away from heat, in case the rubber components and high pressure polythene pieces together the aging deformation

9, the storage of the transport shall avoid stress, bump, rain, and contact corrosive chemical exposure
