摘要
简要介绍了减压孔板的水力特性,通过某球罐区固定式消防冷却水系统的工程实例,对圆缺孔板和圆形孔板分别进行了计算,并将圆形孔板的两种计算结果加以分析比较,提出在罐区稳高压固定式消防冷却水系统中减压孔板应用的建议。
The hydraulic characteristics of restriction orifice plate are briefly introduced and the computation of segmental orifice plate and concentric orifice plate is performed based on the engineering application of a fixed fire fighting system in spherical tanks,and then the results of the concentric orifice plate obtained from two methods are analyzed, and suggestions on the application of restriction orifice plate in steady high -pressure and fixed fire fighting water system in storage tanks are put forward.
