style="text-indent:25px">不銹鋼蒸汽電磁閥：不能在危險場合使，如果工況需要請選擇防爆線圈。安裝電磁閥前，管道必須清洗干凈。建議在閥前安裝過濾器，蒸汽管道安裝疏水閥。在電磁閥發(fā)生故障時，為了及時隔離電磁閥，并保證系統(tǒng)正常運行，較好安裝旁路裝置。安裝時電磁閥線圈向上，并保持垂直位置，電磁閥上箭頭或標記應與管道流向一致，不得安裝在有濺水或漏水的地方。在安裝前，要注意看清產(chǎn)品標牌，認真閱讀使用說明書，判斷產(chǎn)品是否符合使用條件。不能將閥安裝在管道的低凹處，以免因蒸汽冷凝水、雜質(zhì)等沉淀在閥內(nèi)而防礙動作。在管路系統(tǒng)中，安裝在支路上的電磁閥通徑應小于主管道閥門的通徑。在管路剛性不足情況下，建議把閥前管道用支架固定，以免電磁閥工作時引起振動。電磁閥的工作介質(zhì)應清潔無顆粒雜質(zhì)，電磁閥內(nèi)件表面上的污物及過濾器，需定期清潔干凈。電磁閥前后管道上需安裝壓力表，以便觀察管道壓力。河南不銹鋼電磁閥多少錢不銹鋼電磁閥必須具有可靠的密封性能。</p><div

能夠承受連續(xù)開關(guān)（訂貨時可注明）。長時間工作需要選用低發(fā)熱長壽命線圏，防爆場所選用防爆線圏。（訂貨時可注明）。高溫環(huán)境需要選用耐溫線圏加散熱器或線圏短時間通電的方式（如自保持式不銹鋼電磁閥）。工作在震動場所需要選用抗震動線圏,（訂貨時可注明）。根據(jù)環(huán)境要求選擇輔助功能：防爆，手動，防水霧，潛水，定時，帶信號。易爆，易燃環(huán)境；必須選用相應等級的防爆不銹鋼電磁閥(d‖BT4，d‖CT5)。當需要不用電對不銹鋼電磁閥進行現(xiàn)場人工操作時，可選擇帶手動功能不銹鋼電磁閥。露天安裝或粉塵多場合應選用防水，防塵品種（防護等級在IP54以上），用于噴泉或水下管路則必須采用潛水不銹鋼電磁閥（防護等級在IP68）。需要定時開關(guān)的可以選擇定時器裝配在不銹鋼電磁閥上。需要對管路介質(zhì)通斷進行監(jiān)控的，則選用帶信號反饋功能的不銹鋼電磁閥（溫度不超過

style="text-indent:25px">不銹鋼電磁閥按其行程可分為直行程和角行程兩種，按其結(jié)構(gòu)類型分直通單座閥、直通雙座閥、高壓閥、角形閥、套筒閥、隔膜閥、蝶閥、偏心旋轉(zhuǎn)閥等。其中直通閥比較常見，單座閥泄漏量較小，但閥前后壓差不能太大，而雙座閥正好與之相反。高壓閥適合于高靜壓和高壓差的介質(zhì)測量，但在高壓差情況***體對材料沖刷和氣蝕嚴重，一般要考慮閥芯和閥座的材質(zhì)，以提高其使用壽命。在高壓差、高黏度、含懸浮物和顆粒狀物質(zhì)流體的控制中可選用角形閥。隔膜閥更適用于強酸、強堿等強腐蝕性介質(zhì)的控制。蝶閥適用于大流量、低壓差的氣體介質(zhì)。套筒閥采用平衡型閥芯結(jié)構(gòu)，具有低噪聲的特點，是應用較為普遍的閥之一。電磁閥一般斷電可以復位。</p><div
