進口高壓電磁閥
進口高壓電磁閥產(chǎn)品概述
美國沃克(WORK)進口高壓電磁閥(高溫高壓電磁閥,電站電磁閥)用于各種中溫、高溫、常壓、高壓場合,適用與中高溫熱水、導熱油、高溫蒸汽、飽和蒸汽及過熱蒸汽等管路的自動控制;*、航天、船舶重工、核工業(yè)、石化、電力、化學、輕工、機械、科研、給排水、消防、清洗設備、噴泉、管道介質(zhì)自動化控制等領域。是自動化控制工程、項目改造及設備配套的*產(chǎn)品。
進口高壓電磁閥工作原理
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,電磁閥關閉。
