Reliable and optimal valve sizing and selection for process industry

控制阀是控制回路中最常用的最终控制元件，其操纵流动的流体， 例如气体、蒸汽或化合物，以补偿负载扰动并带来实际输出 更接近所需的参考点。在工业自动化、过程控制等领域得到了广泛的应用 工业，化学，发电，化肥，食品加工，石油化工，采矿，天然气 天然气液化、石油和天然气、炼油、饮用水和废水、纸浆和造纸工业， 过程更有利可图，节约能源。控制阀基本上由阀体和 执行器.迄今为止，已经开发了许多类型的控制阀体，例如地球仪阀体阀。一 当为给定应用选择阀类型时，使用的重要因素是流动特性。是 控制阀开度和通过阀的流速之间的关系。还有其他重要 在最终选择阀门时应考虑的因素，如压头损失。调整控制阀的尺寸 是指选择一个具有正确尺寸的节流孔的阀门，以在一定范围内通过所需的流量。的 阀门的类型和尺寸对控制阀的性能起着重要的作用， 系统选择正确的控制阀并不是一件容易的事，必须进行良好的工程判断， 阀门组件尺寸和选择的实践。全面了解工艺操作条件， 阀门将在正确的尺寸和选择是必不可少的，我们建议开发 用于优化阀门尺寸和选择的软件平台。

Control valve is the most commonly used final control element in control loop that manipulates a flowing fluid, such as gas, steam, or chemical compounds, to compensate for the load disturbance and bring the actual output closer to the desired reference point. It has been widely used in Industrial Automation, Process Control Industry, Chemical, Electrical Power Generation, Fertilizer, Food Processing, Petro-Chemical, Mining, Natural Gas Liquefaction, Oil and Gas, Oil Refining, Potable and Waste Water, Pulp and Paper Industry to make the process more profitable and to conserve energy. Control valve essentially consists of a valve body and an actuator. Many styles of control valve bodies, such as globe body valve, have been developed to date. One important factor used when selecting a valve type for a given application is the flow characteristic. It is the relationship between the control valve opening and the flow rate through valve. There are other important factors, such as head loss, that should be considered in making the final valve selection. Sizing a control valve means selecting a valve with the correct size orifice to pass the required flow rate within a certain range. The style and the sizing of the valve can play an important role in the performance of the control valve in the system. Choosing the right control valve is not an easy task, and good engineering judgment must go into the practice of valve assembly sizing and selection. A thorough knowledge of the process operating conditions that the valve will operate in is essential for the correct sizing and selection, and we propose a development of software platform for optimal valve sizing and selection.
