- J41W不銹鋼截止閥應(yīng)用規(guī)范:J41W不銹鋼截止閥,截止閥是指關(guān)閉件(閥瓣)沿閥座中心線移動的閥門。截止閥根據(jù)閥瓣的這種移動形式,閥座通口的變化是與閥瓣行程成正比例關(guān)系。由于該類截止閥的閥桿開啟或關(guān)閉行程相對較短,而且具有非??煽康那袛喙δ?,又由于閥座通口的變化與閥瓣的行程成正比例關(guān)系,非常適合于對流量的調(diào)節(jié)。因此,這種類型的截止閥非常適合作為切斷或調(diào)節(jié)以及節(jié)流使用.1、設(shè)計制造按GB12235-892、結(jié)構(gòu)長度按GB12221-893、法蘭尺寸按JB/G79-944、閥門檢查和試驗按GB13927J41W不銹鋼截止閥性能規(guī)范:型號公稱壓力試驗壓力工作溫度(℃)適用介質(zhì)強度(水)(Mpa)密封(水)空氣(Mpa)低壓密封空氣(Mpa)J41W-16P(R)1.62.41.80.6≤200NITRIC ACIDJ41W-25P(R)2.53.82.80.6≤200硝酸類ACETIC ACID醋酸類NITRIV ACID硝酸類J41W-40P(R)4.06.04.40.6≤200ACETIC ACIDJ41W-64P(R)6.49.67.00.6≤200醋酸類J41W不銹鋼截止閥主要零件材質(zhì)零件名稱ZG1Cr18Ni9Ti系列ZG00Cr18Ni10系列ZG1Cr18Ni12Mo2Ti系列ZG00Cr17Ni14Mo2系列WCB系列閥體/閥蓋ZG1Cr18Ni9TiZG00Cr18Ni10ZG1Cr18Ni12Mo2TiZG00Cr17Ni14Mo2WCB閥瓣ZG1Cr18Ni9TiZG00Cr18Ni10ZG1Cr18Ni12Mo2TiZG00Cr17Ni14Mo21Cr13閥桿ZG1Cr18Ni9Ti00Cr18Ni101Cr18Ni12Mo2Ti00Cr17Ni14Mo21Cr13填料PTFE編織PTFE編織PTFE編織PTFE編織石墨墊片304+PTFE304L+PTFE316+PTFE316L+PTFE石墨+304壓蓋ZG1Cr18Ni9TiZG00Cr18Ni10ZG1Cr18Ni12Mo2TiZG00Cr17Ni14Mo2WCB填料壓環(huán)1Cr18Ni9Ti00Cr18Ni101Cr18Ni12Mo2Ti00Cr17Ni14Mo21Cr13螺栓1Cr17Ni21Cr17Ni21Cr17Ni21Cr17Ni235CrMoA螺母1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Ti45J41W不銹鋼截止閥1.6MPa主要連接尺寸及重量尺寸DN1520253240506580100125150200250300350400Lmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm120140160160200200240240280320360560600700800900重量kg56.5713.516324560801071342684496637501170J41W不銹鋼截止閥2.5MPa主要連接尺寸及重量尺寸DN1520253240506580100125150200250300350400Lmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm120140160160200200240240280320360560600700800900重量kg56.5713.516324560801071342684496637501170J41W不銹鋼截止閥4.0MPa主要連接尺寸及重量尺寸DN1520253240506580100125150200250300350400Lmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm120140160160200200240240280320360560600700800900重量kg56.5713.516324560801071342684917058501234
