闸阀是***常用的截断阀之一，主要用来接通或截断管路中的介质，不适用于调节介质流量，电动闸阀适用的压力、温度及口径范围很大，尤其适用于中、大口径的管道。1、闸阀的主要优点(1)流体阻力小，闸阀阀体内部介质通道是直通的，介质流经闸阀时不改变其流动方向，因而流动阻力较小(2)启闭较省力，启闭时闸板运动方向与介质流动方向相垂直，与截止阀相比、闸阀的启闭较为省力。(3)介质流动方向一般不受限制。介质可从闸阀两侧任意方向流过，均能达到接通或截断的目的。便于安装，适用于介质的流动方向可能改变的管路中。执行标准AdministerStandard设计与制造DesignandManufacture结构长度FaceToFace法兰尺寸FlangeDimension压力-温度PressureTemperatureLating试验-检验spectionAndTestGB122234GB12221GB9113JB79GB9131GB/T13927JB/T9092压力试验PressureTest公称压力NominalPressure1.62.54.06.410.016.0强度试验ShellTest2.43.86.09.615.024.0水密封试验WaterSealTest1.82.84.47.011.018.0上密封试验BackseatTest1.82.84.47.011.018.0气密封试验AirSealTest0.4-0.7主要零件材料及性能MainPartMaterialsandProperty体、盖、板BodyCoverDisc阀杆Stem密封面SealingFace垫片SealingShim填料Packing工作温度WorkingTemperature适用介质SuitableMediumWCB2Cr1313CrSTL木体材料WithBodyMaterial尼龙Nylon增强柔性石墨13Cr/柔性石墨EnhancedFlexibleGraphite1Cr13/FlexibleGraphite08软钢08SoftSteal0Cr18Ni9Ti0Cr17Ni12Mo2TiXD550F(T)PTFE柔性石墨增强柔性石墨FlexibleGraphiteEnhancedFlexibleGraphiteSFB/260SFP/260PTFE≤425水蒸汽油品WaterSteamＯilGoodsWC138CrMoAl25Cr2MoV≤450WC6≤540WC9≤570C5C12≤540ZGCr5Mo≤200硝酸类NitricacidZG1Cr18Ni9Ti1Cr18Ni9Ti≤200醋酸类AceticacidZG1Cr18Ni12Mo2Ti1Cr18Ni12Mo2Ti电装型号规格主要尺寸和重量ElectricActuatorCodeSizeMainDimensi***andWeight1.6MPaDNLDD1D2bn-φd电装型号ElectricActuatorCodeL1HD0重量Weight凸面法兰RFZ940HZ940YZ940WZ940FZ941HZ941YZ941WZ941F16C16P16R16I4020014511085164-18DZW1059059536587.550250160125100164-18DZW105906533659065265180145120184-18DZW105906653659680280195160135208-18DZW15590725365108100300215180155208-18DZW20590787365126125325245210185228-18DZW20590934365173150350280240210248-23DZW205909553651992004003352952652612-23DZW3059011053652542504504053353203012-25DZW3081013434703103005004604103753012-25DZW4581015164703913505505204704353416-25DZW9081016784707294006005805254853616-30DZW12083019375509924506506405855454020-30DZW120830193755011685007007056506084420-34DZW180830223455012226008008407707184820-41DZW250870243232013767009009108407885024-41DZW2508702489320140180010013239508985224-41DZW35011702643570-9001100112013509985428-41DZW50011702935570-100012001255117011005628-48DZW50011703410570-电装型号规格主要尺寸和重量ElectricActuatorCodeSizeMainDimensi***andWeight2.5MPaDNLDD1bn-φd电装型号ElectricActuatorCodeL1HD0重量Weight凸面法兰RFZ940HZ940YZ940WZ940FZ941HZ941YZ941WZ941F2525P25R25I40200145110184-18DZW105905953659150250160125204-18DZW105906533659565265180145228-18DZW105906653659980280195160228-18DZW15590725365113100300230190248-23DZW20590787365132125325270220288-25DZW20590902365181150350300250308-25DZW305909553652062004003603103412-25DZW3081011054702572504504253703612-30DZW3081013434703173005004854304016-30DZW6081015164704123505505504904416-34DZW9083016785507504006006105504816-34DZW120830184955010424506506606005020-34DZW120830193755012745007007306605220-41DZW180870223432014206008008407705620-41DZW250870243232015227009009558756024-48DZW50087024893201617800100010709906424-49DZW50011702643570-9001100118010906628-54DZW80011702935570-10001200130512106828-58DZW80011703410570-4.0MPa40200145110184-18DZW1059063036592凹凸法兰MFMZ940HZ940YZ940WZ941HZ941YZ941W4040P40R40I50250160125204-18DZW105906913659565280180145228-18DZW1059071136510280310195160228-18DZW15590775365115100350230190248-23DZW20590871365163125400270220288-25DZW20590948365190150450300250308-25DZW3081010284702192005503753203812-30DZW3081013254703732506504453854212-34DZW45810
