楔式电动闸阀的特点流动阻力不大，密封面受介质的冲刷和侵蚀小（闸板开启度高）闭阀所需力矩较小。开启时有力度，密封的性能较好，介质流向不受限制，不拢流，不***力。形体简单明了，制做工艺性好，使用范围大。主要零件材料零件名称材料阀体、阀盖WCBZG1Cr18Ni9TiZG1Cr18Ni12MO2TiZGOOCr18Ni10ZG00Cr17Ni14MO2闸板1Cr13ZG1Cr18Ni9TiZG1Cr18Ni12MO2TiZG00Cr18Ni10ZG00Cr17Ni14MO2阀杆1Cr131Crl8Ni9Ti1Cr18Ni12MO2TiOOCr18Ni10OOCrl7Nil4MO2填料PTFEPTFEPTFEPTFEPTFE垫片304+PTFE304+PTFE316+PTFE304+PTFE316+PTFE倒密封座1Cr13A276-410A276-410A276-410A276-410压盖WCBZG1Cr18Ni9TiZG1Ct18Ni12MO2TiZG00CF18Ni10ZGOOCrl7Nil4MO2填料压环1Cr131CF18Ni9Ti1CF15Ni12MO2Ti00Crl8NilOOOCrl7Nil4MO2螺栓35CrMoA1Cr17Ni21Cr17Ni21Cr17Ni21Cr17Ni2螺母45lCr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Tf1Cr18NigTi性能规范阀体材料公称压力(MPa)工作温度（℃)适用介质碳钢C1.6-6.4≤425℃水、油品、蒸汽10.1-16.0不锈钢P1.6-16.0≤200℃硝酸类R醋酸类铬钼钢I1.6-16.0≤550℃蒸汽、油品PN10.0MPa主要连接尺寸及重量(单位:mm)口径DN1520253240506580100125150200250L170190210230240250280310350400450550650手动H175180210230350359373435500614674818970W120120160180240280320360400450560640720Wt(kg)812162032517089130223295560640电动H6807307~6840943105812951295W680680680680720720840840Wt(kg)8297119154256357545770PN6.4MPa主要连接尺寸及重量(单位:mm)口径DN1520253240506580100125150200250300350400L170190210230240250280310350400450550650750850950手动H175180210230350359373435500614674818970114512801450W120120140160200240280320360400400450560640800800Wt(kg)89122532404561891402063274675909001190电动H680730796846943105812951295165019602238W680680680680720720840840107010701130Wi(kg)769611815320830040950576111771948)
