                                                                                                                                  進口蒸汽電磁閥工作原理

                                                                                                                                  1.蒸汽電磁閥為分步動作直接先導式電磁閥,可根據斷電時所處開、關狀態的不同,可分為常閉式電磁閥和常開式電磁閥。

                                                                                                                                  2.常閉蒸汽電磁閥,線圈通電后,銜鐵在電磁力作用下先帶動副閥閥塞提起,主閥閥杯上的流體經副閥流走,減少了作用在主閥閥杯上的壓力,當主閥閥杯上的壓力減少到一定值時,銜鐵帶動主閥閥杯,并利用壓差而使主閥閥杯開啟,介質流通。線圈斷電后,電磁力消失,銜鐵因自重下落復位。同時依靠介質壓力,主副閥得以緊密關閉。

                                                                                                                                  3.常開蒸汽電磁閥,線圈通電后由于吸力作用,動鐵芯下移,把副閥閥塞壓下,副閥關閉,主閥閥杯內壓力上升,當壓力升到一定值時,主閥閥杯的上下壓差一樣,由于電磁力作用,動鐵芯失去主閥閥杯下,壓緊主閥閥座,閥門關閉。線圈斷電時,電磁吸力為零,副閥閥塞和支鐵芯由于彈簧作用向上提起,副閥打開,利用壓差把主閥閥杯推起,主閥打開,介質流通。

                                                                                                                                  進口蒸汽電磁閥主要技術參數
