進口防爆電磁閥
應用范圍:
*、核工業(yè)、船舶重工、石化、電力、化學、輕工、機械、科研、燃氣管網(wǎng)、工業(yè)窯爐、管道介質(zhì)自動化控制等領(lǐng)域。
產(chǎn)品特點:
外觀精美;活塞結(jié)構(gòu);性能穩(wěn)定;專制線圈,不易燒毀;zui適應在爆炸危險場所使用。
主要技術(shù)參數(shù):
進口防爆電磁閥詳細技術(shù)參數(shù):http:///cn/products/610.htm
◆控制方式:常開、常閉、自保持式。
◆電源電壓: DC12~220V; AC24~380V。
◆閥體材質(zhì):鑄鋼、黃銅、鋁、四氟乙烯、不銹鋼。
◆適用介質(zhì):水、氣、油、腐蝕流體等。
◆壓力范圍:0~200MPa
◆溫度范圍:(-200、-50)~(+120、+200、+250)
0~(+300、+450、+600)℃。
◆介質(zhì)粘度:小于50C St(大于時需定制)。
◆防護性能:防塵、防水、防爆。根據(jù)工況選擇。
◆接線方式:接線座式;引線式。
◆連接方式:法蘭、焊接、內(nèi)螺紋(外螺紋和特殊接口可定做或加轉(zhuǎn)接頭)。
工作原理:
常閉:當線圈通電時,電磁鐵芯吸合,卸壓孔打開,主活塞由介質(zhì)壓力推動,打開主閥口,介質(zhì)流通。
當線圈斷電時,主閥口關(guān)閉,介質(zhì)截止。
