特点浮动保温球阀采用单斜面弹性密封圈或V型槽弹性密封圈结构设计，当介质压力较小时，密封圈与球体接触面较小，故有较大的密封比压，确保可靠密封，介质压力圈套时，密封圈与球体接触面积增大，故密封圈能承较大的介质推力而不会损坏。由聚四氟乙烯等密封材料具有两好的自润滑性，与球体的摩擦损小，故球的使用寿命长。主要技术参数主要零件阀体WCBZG1Cr18Ni9TiCF8(304)CF8(304L)ZG1Cr18Ni12Mo2TiCF8M(316)CF3M(316L)球体、阀杆2Cr131Cr18Ni9Ti0Cr18Ni9Ti(304)00Cr19NI11(304L)1Cr18Ni12Mo2Ti0Cr17Ni12Mo2(316)00Cr17Ni14Mo2(316L)密封圈聚四氟乙烯 对位聚苯 PTFE、PPL填料、垫圈V型聚四氟乙烯、柔性石墨环、聚四氟乙烯片、柔性石墨缠绕垫适用工况适用介质水、蒸汽、油品等硝酸等腐蚀性强氧化性介质醋酸等腐蚀性介质尿素等腐蚀性介质适用温度-28~300℃应用规范设计制造按CB12237-89API6DJPI17S-48法兰尺寸按JB79-59、SH3406、GB9113、HC20592-97ANSI B16.5JIS B2212-2214结构长度按GB12221-89ANSI 16.10JIS B202检验试验按GB/T13927-89JB/T9092-99JPI590主要零件阀体WCBZG1Cr18Ni9TiCF8(304)CF8(304L)ZG1Cr18Ni12Mo2TiCF8M(316)CF3M(316L)球体、阀杆2Cr131Cr18Ni9Ti0Cr18Ni9Ti(304)00Cr19NI11(304L)1Cr18Ni12Mo2Ti0Cr17Ni12Mo2(316)00Cr17Ni14Mo2(316L)密封圈聚四氟乙烯 对位聚苯 PTFE、PPL填料、垫圈V型聚四氟乙烯、柔性石墨环、聚四氟乙烯片、柔性石墨缠绕垫适用工况适用介质水、蒸汽、油品等硝酸等腐蚀性强氧化性介质醋酸等腐蚀性介质尿素等腐蚀性介质适用温度-28~400℃-28~500℃应用规范设计制造按CB12237-89API6DJPI17S-48法兰尺寸按JB79-59、SH3406、GB9113、HC20592-97ANSI B16.5JIS B2212-2214结构长度按GB12221-89ANSI 16.10JIS B202检验试验按GB/T13927-89JB/T9092-99JPI590BQ41软（硬）密封球阀主要连接尺寸（GB规格）型号公称通径Dn（mm）尺寸（mm）LDD1D2B-fZ-∮dHD04-GBQ41H16PF（R）3/820140105755514-24-14641203/82515-24-14901653/8321651351007818-24-181051801/24018-34-181602401/25020016012510020-34-182052701/26522018014512022-38-182153501/28025-38-182304001/210028023019016024-32-232705001/212532027022018828-38-253006001/215036030025021830-38-253409001/220040036031027834-312-2540011001/2型号公称通径Dn（mm）尺寸（mm）LDD1D2B-fZ-∮dHD04-GBQ41H25PF（R）3/820140105755514-24-14641203/82515-24-14901653/8321651351007818-24-181051801/24018-34-181602401/25020016012510020-34-182052701/26522018014512022-38-182153501/28025-38-182304001/210028023019016024-38-232705001/212532027022018828-28-253006001/215036030025021830-38-253409001/220040036031027834-312-2540011001/2型号公称通径Dn（mm）尺寸（mm）LDD1D2D6B-fZ-∮dH4-GBQ41H40PF（R）/8201401-24-
