電(dian)磁(ci)脈沖閥工作原理：

　　膜(mo)片把電(dian)磁(ci)脈(mo)沖(chong)(chong)(chong)閥分(fen)成前、后(hou)(hou)二(er)個氣(qi)室(shi)，當接通(tong)壓縮(suo)空氣(qi)通(tong)過節流孔進入后(hou)(hou)氣(qi)室(shi)，此(ci)時后(hou)(hou)氣(qi)室(shi)壓力將膜(mo)片緊(jin)貼閥的輸出口，電(dian)磁(ci)脈(mo)沖(chong)(chong)(chong)閥處(chu)于“關閉”狀態。脈(mo)沖(chong)(chong)(chong)噴吹控制(zhi)儀電(dian)信號消失(shi)，電(dian)磁(ci)脈(mo)沖(chong)(chong)(chong)閥銜鐵(tie)復位，后(hou)(hou)氣(qi)室(shi)放氣(qi)孔關閉，后(hou)(hou)氣(qi)室(shi)壓力升高使(shi)膜(mo)片緊(jin)貼閥出口，電(dian)磁(ci)脈(mo)沖(chong)(chong)(chong)閥又處(chu)于“關閉”狀態。
