J41W不锈钢截止阀应用规范:J41W不锈钢截止阀,截止阀是指关闭件（阀瓣）沿阀座中心线移动的阀门。根据阀瓣的这种移动形式，阀座通口的变化是与阀瓣行程成正比例关系。由于该类阀门的阀杆开启或关闭行程相对较短，而且具有非常可靠的切断功能，又由于阀座通口的变化与阀瓣的行程成正比例关系，非常适合于对流量的调节。因此，这种类型的阀门非常适合作为切断或调节以及节流使用.1、设计制造按GB12235-892、结构长度按GB12221-893、法兰尺寸按JB/G79-944、阀门检查和试验按GB13927产品结构J41W不锈钢截止阀性能规范:型号公称压力试验压力工作温度(℃)适用介质强度(水)(Mpa)密封(水)空气(Mpa)低压密封空气(Mpa)J41W-16P(R)1.62.41.80.6≤200NITRICACIDJ41W-25P(R)2.53.82.80.6≤200硝酸类ACETICACID醋酸类NITRIVACID硝酸类J41W-40P(R)4.06.04.40.6≤200ACETICACIDJ41W-64P(R)6.49.67.00.6≤200醋酸类J41W不锈钢截止阀主要零件材质零件名称ZG1Cr18Ni9Ti系列ZG00Cr18Ni10系列ZG1Cr18Ni12Mo2Ti系列ZG00Cr17Ni14Mo2系列WCB系列阀体/阀盖ZG1Cr18Ni9TiZG00Cr18Ni10ZG1Cr18Ni12Mo2TiZG00Cr17Ni14Mo2WCB阀瓣ZG1Cr18Ni9TiZG00Cr18Ni10ZG1Cr18Ni12Mo2TiZG00Cr17Ni14Mo21Cr13阀杆ZG1Cr18Ni9Ti00Cr18Ni101Cr18Ni12Mo2Ti00Cr17Ni14Mo21Cr13填料PTFE编织PTFE编织PTFE编织PTFE编织石墨垫片304+PTFE304L+PTFE316+PTFE316L+PTFE石墨+304压盖ZG1Cr18Ni9TiZG00Cr18Ni10ZG1Cr18Ni12Mo2TiZG00Cr17Ni14Mo2WCB填料压环1Cr18Ni9Ti00Cr18Ni101Cr18Ni12Mo2Ti00Cr17Ni14Mo21Cr13螺栓1Cr17Ni21Cr17Ni21Cr17Ni21Cr17Ni235CrMoA螺母1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Ti45J41W不锈钢截止阀1.6MPa主要连接尺寸及重量尺寸DN1520253240506580100125150200250300350400Lmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm120140160160200200240240280320360560600700800900重量kg56.5713.516324560801071342684496637501170J41W不锈钢截止阀2.5MPa主要连接尺寸及重量尺寸DN1520253240506580100125150200250300350400Lmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm120140160160200200240240280320360560600700800900重量kg56.5713.516324560801071342684496637501170J41W不锈钢截止阀4.0MPa主要连接尺寸及重量尺寸DN1520253240506580100125150200250300350400Lmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm120140160160200200240240280320360560600700800900重量kg56.5713.51632456080107134268491705850)
