進口氨用電磁閥
進口氨用電磁閥產品概述
美國沃克(WORK)進口氨用電磁閥(液氨電磁閥,氨氣電磁閥,防腐電磁閥)用于各種常溫、常壓、低壓場合,適用于各種腐蝕性介質或帶微粒介質使用;例如酸、酸、各種電鍍液、各種油類、芳香族溶劑、脂肪族溶劑等管路的自動控制;廣泛應用于試驗設備、科研、制藥、電鍍涂裝、清晰設備及農業設備等行業,是化工流體自動化生產設備的*配套產品。
進口氨用電磁閥工作原理
氨用電磁閥常閉型: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,電磁閥關閉。
氨用電磁閥常開型:當線圈通電時,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,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。
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。
