摘　　要：为提高细水雾对油类的灭火性能,研制了一种多喷嘴组合式高压细水雾喷头.设计了一种新型三切向槽式高压细水雾喷嘴,并将该喷嘴安装在组合式喷头本体上,构成多喷嘴细水雾喷头,针对三切向槽式高压细水雾喷嘴进行雾化试验,并对其物化性能进行分析,针对多喷嘴组合式高压细水雾喷头进行灭火试验.试验结果表明,该多喷嘴组合式高压细水雾喷头雾滴直径小,雾化角大,扑灭油类火效率高.A combined sprinkler head is designed for improving the oil fire extinguishing performance of water mist.A new type of three-tangential-groove water mist nozzle is developed,and is set on the combined sprinkler head.The atomizing experiment with the three-tangential-groove water mist nozzle is conducted and analyzed,and the water mist fire extinguishing tests are carried out.The results show that the combined sprinkler head has a small droplet diameter,a big atomizing angle and a good oil fire extinguishing performance.
