限流孔板的计算与应用

Calculation and Application of Current Limiting Orifice Plate

限流孔板作为特殊的管道附件,具有结构简单、易加工、制造成本低、安装方便等优点。它对于管道流量以及压力有很好的限制作用,因此对其孔径的计算有一定的精度要求。本文结合具体实例来介绍限流孔板的计算和选型。只要合理选择和使用,就会起到大作用,既可以节约建设投资,又能保证装置的安全运行,随着限流孔板认识的不断提高,限流孔板在工艺装置中的应用将会越来越广泛,将在降低投资、简化操作、安全运行等方面发挥不可缺少的作用。

As a special pipe accessory,the orifice plate has the advantages of simple structure,easy processing,low manufacturing cost and convenient installation.It has a good restriction on the flow and pressure of the pipeline,so the calculation of its aperture has certain precision requirements.The calculation and selection of orifice plate with concrete examples were introduced.As long as it was reasonably selected and used,it would play a great role in saving construction investment and ensuring the safe operation of the device.With the continuous improvement of the understanding of the current limiting orifice plate,the application of the current limiting orifice plate in the process device will be more and more extensive.It will play an indispensable role in reducing investment,simplifying operation and running safely.
