如何成为CAD制图、工艺流程图设计高手
PID流程图的画法设备的画法与标注
设备的画法与方案流程图基本相同。
与方案流程图不同的是：对于两个或两个以上的相同设备一般应全部画出。
每个工艺设备都应编写设备位号并注写设备名称。与方案流程图中的设备位号应该保持一致。
当一个系统中包括两个或两个以上完全相同的局部系统时，可以只画出一个系统的流程，其他系统用双点画线的方框表示，在框内注明系统名称及其编号。
管道流程线的画法及标注

管道流程线上应用箭头表示物料的流向。
图中的管道与其他图纸有关时，应将其端点绘制在图的左方或右方，并用空心箭头标出物料的流向（进或出），在空心箭头内注明与其相关图纸的图号或序号，在其上方注明来或去的设备位号或管道号或仪表位号。

每条管道都要标注管道代号。横向管道的管道代号注写在管道线的上方;竖向管道则注写在管道线左侧，字头向左。

阀门等管件的画法与标注
管道上的管道附件有阀门、管接头、异径管接头、弯头、三通、四通、法兰、盲板等。这些管件可以使管道改换方向、变化口径，可以连通和分流以及调节和切换管道中的流体。

为了安装和检修等目的所加的法兰、螺纹连接件等也应画出。
管道上的阀门、管件要按需要进行标注。当它们的公称直径同所在管道通径不同时，要注出它们的尺寸。
当阀门两端的管道等级不同时，应标出管道等级的分界线，阀门的等级应满足高等级管的要求。
对于异径管标注大端公称通径乘以小端公称通径。
仪表控制点的画法与标注
画出所有与工艺有关的检测仪表、调节控制系统、分析取样点和取样阀（组）。
仪表控制点用符号表示，并从其安装位置引出。符号包括图形符号和字母代号，它们组合起来表达仪表功能、被测变量、测量方法。
