**Coursera 课程总结：控制阀、执行器与调节阀定位器：操作与设计** 本课程专为工程师、阀门技师、维护人员、仪表技术员以及负责控制阀、执行器和定位器选型、尺寸确定、安装、调试、操作和维护的专业人士设计。 **课程核心内容：** * **基础概念：** 深入回顾控制阀和执行器的作用与功能，并从技术角度解析调节阀定位器在控制阀操作中的工作原理。 * **关键设备详解：** 详细介绍各类控制阀（滑动阀杆式和旋转式，包括快开、线性及等百分比特性）、三通合流/分流控制阀、隔膜执行器（气开上推、气开下推）、柱塞执行器（单动、双动，故障开/关）、齿轮齿条执行器（单动、双动，故障开/关）、曲柄摇杆执行器（单动、双动，故障开/关）、气动定位器（力平衡式、运动平衡式）、数字定位器和I/P转换器的工作原理及结构细节。 * **过程应用与实践：** 通过一系列过程示例和已解算问题，学员将学习如何： * 使用3D和2D模型拆卸和组装不同类型的 the control valves and actuators， * 辨别各种控制阀/执行器组合的净效应（直接作用、反向作用、故障开、故障关等）， * 将执行器从单动配置转换为双动配置， * 将控制阀/执行器组合从故障关配置转换为故障开配置， * 绘制控制阀的安装曲线， * 确定不同阀门开度下的流量和压降， * 将阀门特性与给定应用匹配， * 分析选型过大控制阀的影响， * 探究压差对阀门升程和执行器操作的影响， * 判断何时需要安装定位器。 * **虚拟实践体验：** 课程包含丰富的图表、剖面视图和3D动画，提供虚拟的实践操作体验。 * **学习评估：** 课程最后设有技术测验，包含190多个问题，形式包括判断题、多选题、图片识别、剖面视图分析和已解算问题等，帮助学员巩固知识。 **课程亮点：** * **更新内容：** 新增测验功能，帮助学员测试知识，强调关键学习点。 * **实用性强：** 旨在帮助学员掌握确保工艺装置和管道系统平稳运行所需的必要技能。 * **易于理解：** 课程设计力求技术性与易学性并存，即使是技术培训，也能轻松学习并理解。 * **成长导向：** 完成课程后，学员将为成为一名经验丰富的过程控制工程师或仪表技术员做好准备。 本课程致力于为学员提供宝贵的知识，助力其在过程控制和仪表仪表领域的发展。
June 24 course update:We have added quizzes to help you test your knowledge and emphasize the key learning points. The quiz includes:True/False questionsMulti-choice questionsImages, cross-sectionnal viewsSolved problemsand much more...When you think you've got a good grasp on a topic within the course, you can test your knowledge by taking the quiz. If you pass, wonderful! If not, you can review the videos and notes again or ask us for help in the Q & A section.--This course is for engineers, valve mechanics, maintenance personnel, instrument technicians and other persons responsible for the selection, sizing, installation, commissioning, operation and maintenance of control valves, actuators and positioners.The course begins with a review of the role and function of control valves and actuators and offers a technical perspective for the working of positioners for control valve operation.You will find valuable insights into the working principles and construction details of the following equipment:control valves (sliding stem and rotary / fast opening, linear and equal percentage)mixing and diverting 3-port control valvesdiaphragm actuators (air-to-push-up and air-to-push-down)piston actuators (single acting and double acting / Fail Open (FO) and Fail Close (FC))rack and pinion actuators (single acting and double acting / Fail Open (FO) and Fail Close (FC))scotch yoke actuators (single acting and double acting / Fail Open (FO) and Fail Close (FC))pneumatic positioners (force balance, motion balance)digital positionersI/P convertersThe course then proceeds through a series of process examples and solved problems that require you to:dismantle and assemble various types of control valves and actuators using 3D and 2D modelsidentify the net effect of various control valve/actuator assemblies (direct acting, reverse acting, fail open, fail close...)convert an actuator from single acting to double acting configurationconvert a control valve/actuator assembly from a fail close to a fail open configurationconstruct the installation curve for a control valvedetermine flowrate and pressure drop through control valves for different valve liftsmatch the valve characteristics to the given applicationexamine the effect of selecting a control valve larger than necessaryexamine the effect of differential pressure on the valve lift and actuator operationdetermine when a positioner should be fitted...This will help you develop the necessary skills to ensure your process plant and piping systems run smoothly.The course also includes:extensive graphicscross-sectional views3D animationsThis will give you a virtual practical exposure on control valves, actuators and positioners.In addition, we have included at the end of the course a technical quiz (190+ questions) to help you test your knowledge and emphasize the key learning points.The quiz includes:True/False questionsMulti-choice questionsImages, cross-sectional viewsSolved problemsand much more...So when you think you've got a good grasp on a topic within the course, you can test your knowledge by taking the quiz. If you pass, wonderful! If not, you can review the videos and notes again or ask us for help in the Q & A section.We promise you that even though this is a technical training, you can watch it easily, without pain, but with comprehension, and that after completing it, you won't be an experienced process control engineer or instrument technician but you will be prepared to become one if that is what you like and persist to be.Thank you again for your interest in our online courses. It is a privilege to serve you and make sure that you're learning valuable information with us.WR TrainingSpread the wings of your knowledge
