不锈钢法兰截止阀J41W阀体、阀盖的设计经过严格的计算具有良好的强度、刚度和流通能力。阀盖上设计了上密封座，在全开状态下使填料密封更为可靠并方便填料的更换。填料、垫片亦根据实际工况或用户要求合理选配，可适用于各种压力，温度及介质工况，密封可靠，性能优良。中大口径设置滚动轴承，启闭轻松。不锈钢法兰截止阀J41W有304、316、316L和双相不锈钢等几个材质选择，公称压力1.6MPa-16.0MPa，工作温度-29～550℃的石油、化工、制药、化肥、电力行业等各种工况的管路上，切断或接通管路介质。驱动方式有手动、齿轮传动、电动、气动等。不锈钢法兰截止阀J41W的启闭件是塞形的阀瓣，密封面呈平面或锥面，阀瓣沿流体的中心线作直线运动。阀杆的运动形式，有升降杆式（阀杆升降，手轮不升降），也有升降旋转杆式（手轮与阀杆一起旋转升降，螺母设在阀体上）。不锈钢法兰截止阀J41W产品特点：1、工作行程小，启闭时间短。2、结构简单，制造和维修比较方便。3、适合作为介质的切断或调节及节流使用。4、密封性好，密封面间磨擦力小，寿命较长。5、阀杆开启或关闭行程相对较短，并具有非常可靠的切断动作。6、阀座和阀瓣比较容易修理或更换密封元件时无需把整个阀门从管线上拆下来。不锈钢法兰截止阀J41W产品应用规范:◆设计制造按GB12235-89◆结构长度按GB12221-89◆法兰尺寸按JB/G79-94◆阀门检查和试验按GB13927不锈钢法兰截止阀J41W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醋酸类不锈钢法兰截止阀J41W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1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Ti45不锈钢法兰截止阀J41W主要尺寸连接：★1.6MPa主要连接尺寸及重量尺寸DN1520253240506580100125150200250300350400Lmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm120140160160200200240240280320360560600700800900重量kg56.5713.516324560801071342684496637501170★2.5MPa主要连接尺寸及重量尺寸DN1520253240506580100125150200250300350400Lmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm120140160160200200240240280320360560600700800900重量kg56.5713.516324560801071342684496637501170★4.0MPa主要连接尺寸及重量尺寸DN1520253240506580100125150200250300350400Lmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm120140160160200200240240280320360560600700800900重量kg56.5713.516324560801071342684917058501234★6.4MPa主要连接尺寸及重量尺寸DN15202540506580100125150Lmm170190210230260300340380430550Hmm195228250325360410450485537646Wmm140160180200240280320360400450重量kg1013151925354856125157★10.0MPa主要连接尺寸及重量尺寸DN1520253240506580100125150200250300Lmm170190210230260300340380430500550650775900Hmm19522825032536041045048553784092510151200Wmm100100120160160180200200240-----重量kg1012172530406892107-3105908501040★16.0MPa主要连接尺寸及重量尺寸DN1520253240506580100125150200Lmm170190210230260300340380430500550650Hmm
