产品概述Q41F手动法兰式不锈钢球阀球阀主要用于截断或接通介质，也可用于流体的调节与控制。与其它阀类相比，球阀具有如下的一些优点：1、流体阻力小，球阀是所有阀类中流体阻力最小的一种，即使是缩径球阀，其流体阻力也相当小。2、开关迅速、方便，只要阀杆转动90°，球阀就完成了全开或全关动作，很容易实现快速启闭。3、密封性能好。球阀阀座密封圈一般采用聚四氟乙烯等弹性材料制造，易于保证密封，而且球阀的密封力随着介质压力的增加而增大。4、阀杆密封可靠。球阀启闭时阀杆只作旋转运动，因此阀杆的填料密封不易被破坏，而且阀杆倒密封的密封力随着介质压力的增加而增大。5、球阀的启闭只做90°转动，故容易实现自动化控制和远距离控制，球阀可配置气动装置、电动装置、液动装置、气液联动装置或电液联动装置。6、球阀通道平整光滑，不易沉积介质，可以进行管线通球。主要性能规范CapabilityCriterion设计与制造结构长度法兰尺寸压力-温度试验-检验GB122237GB12221GB9113JB79GB9131GB/T13927JB/T9092压力试验PressureTest公称压力NominalPressure1.62.54.0强度试验ShellTest2.43.86.0水密封试验WaterSealTest1.82.84.4气密封试验AirSealTest0.4-0.7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RFQ41FQ41PPL16P16R15130956545144-1478140201401057555144-1484160251501158565144-14951803216513510078164-181502504018014511085164-1815030050200160125100184-1817035065220180145120204-1819535080250195160135208-18215400100280215180155208-18250500125320245210185228-18265600150360280240210248-232708002004003352952652612-2333012002.5MPa15130956545164-14103140凸面法兰RFQ41FQ41PPL25P25R201401057555164-14112160251501158565164-141231803216513510078184-181502504018014511085184-1815630050200160125100208-1817235065220180145120228-1819735080250195160135228-23222400100280230190160248-23253500125320270220188288-25275600150360300250218308-252868002004003603102783412-253401200规格主要尺寸SizeMainDimensions4.0MPaDNLDD1D2D6bn-φdHD0凹凸法兰MFMQ41FQ41PPL40P40R1513095654540164-1410314020140105755551164-1411216025150115856558164-14123160321801351007866184-18150250402001451108576184-181562505022016012510088204-1817235065250180145120110228-1819735080280195160135121228-18222450100320230190160150248-23253450125400270220188176288-25275600150400300250218204308-252868002005503753202822603812-3034012006.4MPa15165105755540184-14105140凹凸法兰MFMQ41FQ41PPL64P64R20190125906851204-18125160252161351007858224-18135250322291501108266244-23150350402411651259576244-231653505029217513510588264-2317545065330200160130110288-2320045080356210170140121308-23210600100432250200168150328-25250700125508295240202176368-302951100150559340280240204388-343401500)
