【摘要】：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。
[Abstract]:A special sprinkler with independent intellectual property rights for glass fire prevention and separation has been developed. The cold water distribution of the special sprinkler developed by ourselves is compared with that of the WS window glass nozzle and the domestic side spray nozzle. The distribution of water on the glass, the distribution of water on the glass, the flow coefficient K value and so on are compared and analyzed under the condition of different installation distance between the three kinds of sprinklers. The results show that, The spraying effect of the self-made special sprinkler for glass fire prevention and separation is remarkable, which can reach or even exceed the spraying effect of WS window glass sprinkler, but the spraying effect of common side spray head is the worst.
