开发了具有自主知识产权的玻璃防火分隔专用喷头.通过对自行研制的专用喷头与WS窗玻璃喷头及国内普通侧喷喷头的冷态布水情况开展对比试验,对在不同压力、与玻璃之间不同安装距离的情况下,3种喷头在玻璃上的布水喷洒、水在玻璃上的分布情况、流量系数K值等进行对比分析研究.结果表明,自行研制的玻璃防火分隔专用喷头的喷洒效果显著,能达到甚至超过WS窗玻璃喷头的喷洒效果,而普通侧喷喷头的喷洒效果最差.%A special sprinkler of glass fire separation with indepen-dent intellectual property was developed.The comparison test of the special sprinkler, WS window sprinkler and ordinary side spray nozzle in China was carried out by cold water.The water spray, the distribution of water on glass and the discharge coefficient K were compared and analyzed.The results showed that, the special sprin-kler is remarkable,it can reach even more than the WS sprinkler, and the general spray sprinkler has the worst spray effect.
