PQ640H气动偏心半球阀

气动偏心半球阀说明：PQ640H气动偏心半球阀利用偏心阀体，偏心球体和阀座，阀杆作旋转运动时在共同轨迹自动定心，关闭过程中越关越紧，*达到良好的密封目的。阀门的球体和阀座*脱离，消除了密封圈的磨损，克服了传统球体阀座与球体密封面始终磨损的问题，非金属弹性材料被嵌入金属座中，阀座金属面受到良好的保护。本产品特别适用于钢铁业，铝业，纤维，微小固体颗粒，纸浆，煤灰，石油气等介质。圣核阀门制造(上海)有限公司专业生产PQ640H气动偏心半球阀,如需另外定制特殊规格的PQ640H气动偏心半球阀,气动偏心半球阀主要材料序号名称代号材料WCB304 CF8316 CF8M1阀体 WCB ZG230-4500Cr18Ni90Cr18Ni12Mo2Ti2下端盖 Q235-A1Cr18Ni9Ti0Cr18Ni12Mo2Ti3内六角圆柱头螺钉GB/T70-2000Q235-A1Cr17Ni20Cr18Ni12Mo2Ti4下固定轴调节螺栓 Q235-A1Cr17Ni21Cr17Ni25六角螺母GB/T6710-2000Q235-A1Cr17Ni21Cr17Ni26下垫片 不锈钢 柔性石墨；PTFE；316夹柔性石墨7下轴承 0Cr18Ni9Ti0Cr18Ni9Ti0Cr18Ni12Mo2Ti8下固定轴 2Cr133040Cr18Ni12Mo2Ti9球体 ZG2Cr130Cr18Ni90Cr18Ni12Mo2Ti10阀座压圈 Q225-A1Cr18Ni9Ti0Cr18Ni12Mo2Ti11阀座 Q225-APTFE/1Cr18Ni12Mo2TiPTFE/1Cr18Ni12Mo2Ti12内六角圆柱头螺钉GB/T70-2000Q235-A1Cr17Ni21Cr17Ni213阀座垫片 不锈钢 柔性石墨1Cr17Ni20Cr18Ni12Mo2Ti14阀杆 2Cr131Cr18Ni9Ti0Cr18Ni12Mo2Ti15上轴承 0Cr18Ni9Ti0Cr18Ni9Ti0Cr18Ni12Mo2Ti16对开圆环 1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Ti17定位圈 1Cr131Cr18Ni9Ti1Cr18Ni9Ti18填料 柔性石墨柔性石墨；PTFE柔性石墨；PTFE19六角螺塞垫片 0Cr18Ni9Ti0Cr18Ni9Ti0Cr18Ni9Ti20六角螺塞 2Cr131Cr17Ni21Cr17Ni221六角螺塞 2Cr131Cr17Ni21Cr17Ni222支架 WCB ZG230-450WCB；304WCB；30423双头螺栓GB/T901-198835CrMoA1Cr17Ni21Cr17Ni224六角螺母GB/T6170-2000Q245-A0Cr18Ni90Cr18Ni925填料压套 1Cr131Cr18Ni12Mo2Ti/1Cr18Ni91Cr18Ni12Mo2Ti/1Cr18Ni926填料压板 WCB0Cr18Ni90Cr18Ni927双头螺栓GB/T901-198835CrMoA1Cr17Ni21Cr17Ni228六角螺母GB/T6170-2000Q245-A0Cr18Ni0Cr18Ni29六角螺栓GB/T5783-200Q235-A1Cr17Ni21Cr17Ni230驱动装置    31六角螺塞垫片 0Cr18Ni9Ti0Cr18Ni9Ti0Cr18Ni9Ti32六角螺塞 2Cr130Cr18Ni9Ti0Cr18Ni9Ti 气动偏心半球阀性能范围材料性能材料代号WCB304316304L316L321ZG2300Cr18Ni9（CF8）1Cr18Ni12Mo2Ti（CF8M）00Cr18Ni10（CF3）00Cr17Ni14Mo2（CF3M）ZG7Cr18Ni9T（F347）适用介质水、油品、蒸汽硝酸类醋酸类强氧化介质尿素等腐蚀介质硝酸类测试范围 Mpa项目公称压力壳体压力试验密封测试上密封测试低压密封测试探伤测试试验介质水 Mpa水 Mpa水 Mpa气 MpaGB/T6440-1992时间（S）12060600.5~0.6压力测试1.0Mpa1.51.11.1 1.6Mpa2.41.761.76 2.5Mpa3.752.752.75本资料出自圣核阀门制造(上海)有限公司http://www.4000678178.com 如需转载请注明。本文关键词：PQ640H气动偏心半球阀本文URL：http://4000678178.com/qiufa/3.html
