|
| |
摘要:近年来出现了一种新的消火栓减压孔板安装方式,即将孔板安装在与消火栓出水端相连接的固定接口内。为准确获取消火栓与孔板组合局部阻力系数ξ做了试验,并就其应用进行了讨论。 关键词:室内消火栓 减压孔板 measurement of local resistance coefficient of indoor water hydrant and orifice component jia wei abstract: a new installation of orifice pressure reducer for indoor fire hydrant, which the orifice has to be located at a fixed joint attached to the outlet of hydrant, has appeared recently. the experiment to determine the exact value of the local resistance coefficient of the hydrant and orifice component has been presented and the application of the results discussed.
