产品概述保温截止阀，也叫截门，是使用最广泛的一种阀门，它之所以广受欢迎，是由于开闭过程中密封面之间摩擦力小，比较耐用，开启高度不大，制造容易，维修方便，不仅适用于中低压，而且适用于高压。它的闭合原理是，依靠阀杠压力，使阀瓣密封面与阀座密封面紧密贴合，阻止介质流通。该阀适用于化工、化肥行业的管路上，夹套内涵入蒸汽能防止介质结晶。应用规范1、设计制造按GB12234-89GB12234-892、结构长度按GB12221-89GB12221-893、法兰尺寸按JB/T79-94JB/779-944、阀门检查和试验按GB13927试验压力及主要性能规范型号公称压力试验压力适用温度适用介质保温套压力ShellSealBJ45W-25P2.53.752.75≤200Aceticurea≤1.3BJ45W-40P4.06.04.4BJ45W-64P6.49.06.6AceticureaBJ45W-25P2.53.752.75BJ45W-40P4.06.04.4BJ45W-64P6.49.06.6主要零件材质零件名称LTEMZG1CR18NI9TI系列ZGOOCR18NI10系列ZG1Cr18Ni12MO2Ti系列ZGOOCR17NI14MO2系列WCB系列阀体/阀盖世BODY/CAPZG1CR18NI9TIZGOOCR18NI10ZG1Cr18Ni12MO2TiZGOOCR17NI14MO2WCB闸板WEDGEZG1CR18NI9TIZGOOCR18NI10ZG1Cr18Ni12MO2TiZGOOCR17NI14MO21Cr13阀杆STEM1CR18NI9TI00cr18ni101CR18NI12MOTIOOCR17NI14MO1Cr13填料PACKINGPTFE纺织PTFE纺织PTFE纺织PTFE纺织石墨GRAPHITE垫片GASKET304L+PTFE304L+PTFE316L+PTFE316L+PTFE石墨+304GRAPHITE+304压盖GLANDFLANGEZG1CR18NI9TIZG00CR18ni10ZG1Cr18Ni12MO2TiZGOOCR17NI14MO2WCB填料压环STUFFINGRING1CR18NI9TI00CR18NI101Cr18NI12MOTIOOCR17NI14MO1Cr13螺栓BOLT1cr17ni21CR17NI21Cr17NI21Cr17Ni235CrMoA螺母NUT1cr18ni9ti1CR18NI9TI1Cr18NI9ti1Cr18NI9ti45主要外形尺寸及重量PN(MPa)DN(mm)尺寸(mm)重量kgLL1H3-GDD1D2bZ-φdDo2.515200502101/21057555164--φ141201420220502401/21158565164--φ141401825220502501/213510078184--φ181602532250552701/214511085184--φ181603040270603101/2160125100204--φ181603650300603303/4180145120228-φ182404065350653603/4195160135228-φ182405480380704003/4230190160248-φ2328070100430754801270220188288-φ25320100125490805501300250218308-φ253601301505709062013302802483212-φ253601702006909575013953403023612-φ254002504.015200502101/21057555164--φ141201420220502401/21158565164--φ141401825220502501/213510078184--φ181602532250552701/214511085184--φ181603340270603101/2160125100204--φ181604150300603303/4180145120228-φ182404565350653603/4192160135228-φ182406280380704003/4230190160248-φ2328080100430754801270220188288-φ25320100125490805501300250218308-φ253601301505709062013502952583412-φ303601852006909575014153553154012-φ34400268)
