德國萊克(LIK)品牌:進口常開電磁閥它廣泛應用于船舶重工、測試設備、加熱設備、液壓設備等,工作溫度在300℃以上的導熱系統中。 產品特點: 閥芯均為不銹活塞式,活塞環用特殊耐溫、耐磨材料制作;活塞與金屬閥腔不產生直接摩擦,閥體安裝方向無限制;特制線圈,并采用散熱的結構方式,因此不易燒毀;長時間停止動作重新啟動,動作同樣靈敏;zui低啟動壓力0.2MPa。 主要技術參數: 產品規格: | DN0.5~DN200 | 閥體材質: | 不銹鋼 | 適用介質: | 油、蒸汽、腐蝕流體等 | 溫度范圍: | +300~+450℃ | 防護性能: | 防潮、防爆(Exd IICT5)、防腐 | 接線方式: | 接線座式;引線式;插頭式 | 控制方式: | 常開、常閉 | 電源電壓: | DC24~127V; AC36~380V | 連接方式: | 內螺紋、法蘭(外螺紋和特殊接口可定做或加轉接頭) |
工作原理: 常閉:當線圈通電時,先導閥芯吸合,先導孔打開,閥上卸壓,活塞靠下腔介質壓力推動,電磁閥打開;當線圈斷電時,先導閥芯靠彈簧復位,先導孔關閉,閥上腔由活塞節流孔增壓和復位彈簧的推力,閥關閉。 常開:當線圈通電時,先導孔關閉,閥上腔由活塞節流孔增壓和復位彈簧的推力,電磁閥關閉。當線圈斷電時,先導閥芯靠彈簧復位,先導孔打開,閥上腔卸壓,活塞靠下腔介質壓力推動,電磁閥打開。 規格尺寸: 產品代碼 | GN815 | 公稱通徑 | 選用《ZCD系列直動式電磁閥》、《ZC系列中低壓電磁閥》中的標準口徑 | 適用壓力 | 選用《ZCD系列直動式電磁閥》、《ZC系列中低壓電磁閥》中的壓力范圍 | 連接尺寸 | 選用《ZCD系列直動式電磁閥》、《ZC系列中低壓電磁閥》中的接口尺寸(或定制) | 閥體體質 | 不銹鋼、304或316 | 特殊功能 | (其它功能可定制) |
注:出口端壓力大于進口端壓力,介質會反向導通。可安裝止回閥或訂制自帶止回功能的閥。 Applications: It is widely used in shipbuilding Heavy Industry, test equipment, heating equipment, hydraulic equipment, the working temperature above 300 ℃ thermal systems. Features: Are stainless steel piston valve, piston ring with a special temperature, wear-resistant material; piston valve chamber with the metal does not have a direct friction, the valve mounting direction unlimited; special coil structure and way of using heat, it is not easy burned; long time to restart the stopped action, action as sensitive; minimum starting pressure 0.2MPa. Main technical parameters: Specifications: | DN0.5~DN200 | Body material: | Stainless Steel | Medium: | Oil, steam, corrosive fluids | Temperature range: | +300 ~ +450 ℃ | Protection performance: | Moisture-proof, explosion-proof (Exd IICT5), anti-corrosion | Wiring: | Terminal Block Type; lead type; male | Control: | Normally open, normally closed | Power supply voltage: | DC24 ~ 127V; AC36 ~ 380V | Connection: | Thread, flange (male and special interfaces or add custom adapter) |
