产品概述：不锈钢法兰球阀材质是不锈钢的，主要用于对具有腐蚀性，压力和卫生环境要求较高的地方。球阀是近年来被广泛采用的一种新型阀门。不锈钢法兰球阀具有以下优点：1．流体阻力小，其阻力系数与同长度的管段相等。2．结构简单、体积小、重量轻。3．紧密可靠，目前球阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。4．操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。5．维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。6．在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。7．适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。主要零件材料：MaterialsOfmainParts阀体BodyZG1Cr18Ni9TiCF8CF3ZG1Cr18Ni12Mo2TiCF8MCF3M球体阀杆BallStem1Cr18Ni9Ti304304L1Cr18Ni12Mo2Ti316316L阀座Seat聚四氟乙烯PTFE加坡纤增强聚四氟乙烯PTFE+Glass对位聚笨PPL垫片Shim聚四氟乙烯PTFE不锈钢/柔性石墨StainlessSteel/flexibleGraphite齿形垫片ToothProfileGasket阀杆座StemSeat聚四氟乙烯PTFE不锈钢/柔性石墨StainlessSteel/FlexibleGraphite填料Packing聚四氟乙烯PTFE增强柔性石墨EnhancedFlexibleGraphite填料压盖Gland1Cr18Ni9Ti304304L1Cr18Ni12Mo2Ti316316L温度Temperature-29～150(聚四氟乙烯PTFE)-29～200(加玻纤增强聚四氟乙烯PTFE+GLASS)-29～300(对位聚笨PPL)介质Medium水蒸汽油品WatersteamOilgoods硝酸类NitricAcid强氧化介质strongeyoxidablemedium醋酸类AceticAcid尿素类Urea主要外型尺寸：MainouterSize1.6MPaDNLDD1D2bn-φdHD0凸面法兰RFQ41FQ41PPL16C16P16R15130956545144-1478140201401057555144-1484160251501158565144-14951803216513510078164-181502504018014511085164-1815030050200160125100184-1817035065220180145120204-1819535080250195160135208-18215400100280215180155208-18250500125320245210185228-18265600150360280240210248-232708002004003352952652612-2333012002.5MPa15130956545164-14103140凸面法兰RFQ41FQ41PPL2525P25R201401057555164-14112160251501158565164-141231803216513510078184-181502504018014511085184-1815630050200160125100208-1817235065220180145120228-1819735080250195160135228-23222400100280230190160248-23253500125320270220188288-25275600150360300250218308-252868002004003603102783412-253401200规格主要尺寸：SizeMainDimensions4.0MPaDNLDD1D2D6bn-φdHD0凹凸法兰MFMQ41FQ41PPL4040P40R1513095654540164-1410314020140105755551164-1411216025150115856558164-14123160321801351007866184-18150250402001451108576184-181562505022016012510088204-1817235065250180145120110228-1819735080280195160135121228-18222450100320230190160150248-23253450125400270220188176288-25275600150400300250218204308-252868002005503753202822603812-3034012006.4MPa15165105755540184-14105140凹凸法兰MFMQ41FQ41PPL6464P64R20190125906851204-18125160252161351007858224-18135250322291501108266244-23150350402411651259576244-231653505029217513510588264-2317545065330200160130110288-2320045080356210170140121308-23210600100432250200168150328-25250700125508295240202176368-302951100150559340280240204388-343401500)
