德國萊克LIK品牌:進口螺紋低溫電磁閥應用范圍、它廣泛應用于航天、船舶重工、化工、冷凍設備、食品醫(yī)設備等制冷管道系統(tǒng)中。
產(chǎn)品特點: 閥芯均為不銹鋼活塞式,活塞環(huán)用特殊耐低溫、耐磨材料制作;活塞與金屬閥腔不產(chǎn)生直接摩擦,閥體安裝方向無限制;特制線圈,不易燒毀;長時間停止動作重新啟動,作同樣靈敏。
Applications: It is widely used in aerospace, shipbuilding Heavy Industry, chemical, refrigeration equipment, Medical equipment, food refrigeration piping systems.
Features: Spool is stainless steel piston, piston ring with a special low temperature resistant, wear-resistant material; the piston and the metal does not produce direct friction valve chamber, valve mounting direction unlimited; special coil, not easy to burn; a long time to stop action to re-start, for the same sensitivity

工作原理: 常閉:當線圈通電時,先導閥芯吸合,先導孔打開,閥上腔卸壓,活塞靠下腔介質(zhì)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(guān)閉,閥上腔由活塞節(jié)流孔增壓和復位彈簧的推力,電磁閥關(guān)閉。 常開:當線圈通電時,先導孔關(guān)閉,閥上腔由活塞節(jié)流孔增壓和復位彈簧的推力,電磁閥關(guān)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(zhì)壓力推動,電磁閥打開。
