氣壓電磁閥是一種電磁能轉換為機械能的電磁元件，廣泛應用於自動化設備中，其原理是利用電磁線圈激磁產生電磁力，再藉由電磁力推動閥體內部的閥軸產生位移，而斷電後則利用另一端彈簧將閥軸回歸至中立位置，進而完成開（ON）或閉（OFF）的作動。目前國內業界所生產的傳統氣壓電磁閥，大多尚未考量高壓氣體流經閥室衍生的流動阻力所造成的能量損耗，即多未具備節能特性，且近年來全球能源日益枯竭各國也積極地投入大量的人力與物力於綠色節能的研發上。有鑑於此，本文將進一步改善傳統氣壓電磁閥室內產生之流動阻力，藉以達到節能效果。本文主要研究工作分為兩部份，第一部份為應用CFD軟體對高壓氣體流經閥室進行了模擬分析，針對流出型與流入型等氣壓電磁閥重新設計閥軸幾何外觀以達到節能目的。第二部分則將CFD模擬出的最佳果，經由加工實體閥軸後，驗證初步模擬數值與實驗結果之誤差值。最後利用基於LabVIEW圖控程式所製作的最低操作壓力實驗平臺，並配合FESTO比例壓力閥來精準調控壓力輸出和使用SMC壓力開關與壓力感測器等儀器，來量測閥軸產生位移時之最低操作壓力值，並得到具體使用閥軸做過流動力補償設計前後之節能比例。

Pneumatic Solenoid Valve is an electromagnetic element which can convert electromagnetic energy into mechanical energy .It is broadly used in many industrial fields, such as the automation machinery, etc. it’s principle is utilizing electromagnetic coil excitation to generate electromagnetic force, and then this force pushes the valve spool inside the valve body to produce displacement. While power supply interrupts, the valve spool will be pulled to the neutral position by a spring at the other end, sequentially complete the open (ON) or closed (OFF) function. Currently, in domestic pneumatic electromagnetic valves, the energy loss resulting from flow resistance are almost not considered, which is generated by the high-pressure gas flowing through the valve chamber. They don’t have energy-saving characteristics. In recent years, the global energy depletion is also forcing many countries to invest a lot of manpower and resources to develop energy-saving technology .In view of this, this paper will talk about the further improvement of the flow resistance generated by the traditional pneumatic solenoid valve chamber ,so as to save energy. The research task is divided into two parts. the first part is the simulation analysis of the application of CFD. The analysis result is used to redesign the type of valve spool outflow and inflow’s geometric appearance. Finally to achieve the goal of designing an energy saving with flow force compensation. The second part is using the best result of CFD simulation to manufacture
valve spool, and to test and calculate the error value between the preliminary simulation number value and the final experimental result error value.Lastly, the minimum operating pressure produced with LabVIEW graphical program was used
to test the experimental platform. In addition, FESTO proportional pressure valve was used to accurately control pressure output and operate instruments, including SMC pressure switch and pressure sensor, to measure the minimum operating pressure of valve spool displacement. Thus, the specific energy-saving efficiency of the flow force compensation design using valve shafts was calculated.
