一、产品概述:Z641H气动碳钢法兰闸阀（Z641H、Z641Y、Z641W气动闸阀、气动铸钢闸阀、气动不锈钢闸阀、气动碳钢闸阀、铬钼钢气动闸阀、气动法兰闸阀）：本阀是一种最常见的启闭阀，利用闸板的上下工作来接通(全开)和截断(全关)管道中的流体介质。性能可靠、操作切换和维修方便，已被石油、化工、海运等部门广泛用于对各类介质控制。二、产品特点：1、气动闸阀配有气动执行机构和手动机构；2、闸阀执行器采用双层气缸结构，它与单气缸式气动闸阀相比，提升力增大了一倍；3、解决了单气缸式气动闸阀的某些阀板在阀体内楔死而打不开的弊病；4、具备缓冲机构，能有效地减轻关闭阀门时由于活塞下行冲击而造成的阀板密封面和阀体密封面的磨损，同时也能避免闸板卡死的现象；5、流体阻力小，密封面受介质的冲刷和侵蚀小(闸板开启高度高)；6、开启较有力，密封性能好，介质流向不受限制，不扰流，不降压力；7、形体简单，制造工艺性好，适用范围广。三、执行标准：设计与制造结构长度法兰尺寸压力-温度试验-检验GB12234GB12221GB9113JB79GB9131GB/T13927JB/T9092四、压力试验：公称压力1.62.54.06.410.016.0强度试验2.43.86.09.615.024.0水密封试验1.82.84.47.011.018.0上密封试验1.82.84.47.0411.018.0气密封试验0.4-0.7五、主要零件材料及性能：体盖板阀杆密封面垫片填料工作温度℃适用介质WCB2Cr1313CrSTL本体材料尼龙增强柔性石墨1Cr13/柔性石墨08软钢0Cr18Ni9Ti0Cr17Ni12Mo2TiXD550F（T）PTFE柔性石墨增强柔性石墨SFB/260SFP/260PTFE≤425水、蒸汽、油品WC138CrMoA125Cr2MoV≤450WC6≤540WC9≤570ZGCr5Mo≤540ZG1Cr18Ni9Ti1Cr18Ni9Ti≤200销酸类ZG1Cr18Ni12Mo2Ti1C18Ni12Mo2Ti≤200醋酸类六、主要外形和连接尺寸mm：Z641H、Z641Y、Z641W，1.6MPa尺寸DN1520253240506580100125150200250300350400450500600Lmm130150160180200250265280300325350400450500550600650700800Hmm1751802102103503583734355006146748181225141516301780205021812599Wmm180180200200200240240280320360360400450500500600720720720Z641H、Z641Y、Z641W，2.5MPa尺寸DN1520253240506580100125150200250300350400450500600Lmm130150160180200250265280300325350400450500550600650700800Hmm1751802102103503583734355006146748181225141516301780205021812599Wmm180180200200200240240280320360360400450500500600720720720公称通径DNLDD1D2bZ-ΦdHH1D0WT(Kg)CZ6s40H-16CCZ6s40Y-16PCZ6s40Y-16R50250160125100164-Φ189505701803665270180145120184-Φ1810505961805380280195160135208-Φ18108063520072100300215180155208-Φ18114564525090125325245210185228-Φ181210685250120150350280240210248-Φ1813007203201322004003352952652612-Φ2316609404002582504504053553203012-Φ25179010204002973005004604103753012-Φ25199011504504203505505204704353416-Φ25209011704505584006005805254853616-Φ30229013255008404506506405855454020-Φ302485146550011105007007056506084420-Φ342640159055013806008008407707184820-Φ412940172055016207009009108407885024-Φ41345019606001966800100010209508985224-Φ413650219060022829001100112010509985428-Φ41381524008002495100012001255117011105628-Φ48400026508002760公称通径DNLDD1D2bZ-ΦdHH1D0WT(Kg)CZ6s40H-25CZ6s40Y-25PCZ6s40Y-25R50250160125100204-Φ189505701803865270180145120228-Φ1810505961805580280195160135228-Φ18108063520076100300230190160248-Φ23114564525094125325270220188288-Φ251210685250126150350300250218308-Φ2513007203201362004003603202783412-Φ2516609404002652504504253703323612-Φ30179010204003003005004854303905016-Φ30199011504504363505505504904484416-Φ34209011704505804006006105505054816-Φ34229013255008604506506606005555020-Φ342485146550012605007007306606105220-Φ412640159055014206008008407707185620-Φ413940172055017107009009558758156024-Φ48345019606002105800100010709909306424-Φ4836502190600231090011001180109010256628-Φ54381524008002620100012001305121011406828-Φ58400026508002960公称通径DNLDD1D2D6bZ-ΦdHH1D0WT(Kg)CZ6s40H-40CZ6s40Y-40PCZ6s40Y-40R5025016012510088204-Φ189505702004265280180145120110228-Φ1810505962006880320195160135121228-Φ18108063525084100350230190160150248-Φ231145645320102125400270220188176288-Φ251210700320135150450300250218204308-Φ2513307504001562005503753202822603812-Φ3016609404002762506504453853453134212-Φ34182010504503063007505104504083644616-Φ34199011504505103508505705104654225216-Φ34211011905007204009506555855354745816-Φ4123351370550105045010506806105605246020-Φ41249015105501320500115075567206125766220-Φ4826401590550180060013508907957306786220-Φ54294017206002160Z641H气动碳钢法兰闸阀（Z641H、Z641Y、Z641W气动闸阀、气动铸钢闸阀、气动不锈钢闸阀、气动碳钢闸阀、铬钼钢气动闸阀、气动法兰闸阀）生产商供应商上海炎唐工业装备有限公司，中国名牌产品，上海市知名品牌；通过ISO9001、TS等认证。致力于阀门的专业研发生产，为用户提供高品质闸阀产品。)
