一、气动保温球阀概述气动保温球阀具有良好的保温保冷特性，且阀门的通径与管径一致，同时又能有效降低管路中介质热量损失。主要用于石油、化工、冶金、制药、食品等各类系统中，以输送常温下会凝固的高粘度介质。由于采用整体式结构，因而保温球阀比一般球阀何种更小，重量更轻，且无外漏，密封性能良好，夹套采用碳素钢管焊接比铸造的更加耐压牢固。气动保温球阀技术规范：设计标准：A***EB16.34GB/T12224结构长度：A***EB16.10GB/T12221连接法兰：A***EB16.5、JB/T79驱动方式：手动、电动、气动试验和检验：JB/T9092API598适用介质：重油、胶类等易凝固介质二、气动保温球阀技术规范设计依据GB标准设计标准GB/12237结构长度法兰连接华尔士公司标准连接法兰尺寸GB/9113、JB/T79试验和检验JB/T9002三、气动保温球阀主要零件材质表序号零件名称材质CDR1阀盖WCBZG1C/18Ni9TiZG1Cr18Ni12M2Ti2垫片PTFEPTFEPTFE3阀座PTFEPTFEPTFE4球体1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Ti5阀座PTFEPTFEPTFE6夹套阀体WCBZG1Cr18Ni9TiZG1Cr18Ni12Mo2Ti7螺栓351Cr18Ni9i1Cr18Ni12Mo2Ti8阀杆1Cr131Cr18Ni9Ti1Cr18Ni12Mo2Ti9垫片PTFEPTFEPTFE10填料PTFEPTFEPTFE11衬套PTFEPTFEPTFE12弹垫WCBZG1Cr18Ni9TiZG1Cr18Ni12Mo2Ti13垫片351Cr18Ni9Ti1Cr18Ni9Ti14螺母351Cr18Ni9Ti1Cr18N19Ti15连接支架1Cr18Ni9Ti1Cr18Ni9Ti1Cr18Ni9Ti16螺栓351Cr18Ni9Ti1Cr18Ni9Ti17连接套351Cr18Ni9Ti1Cr18Ni9Ti18位置指示器塑料塑料塑料四、气动保温球阀外形连接尺寸通径外形尺寸连接法兰尺寸dLL1L2L3HH1GDD1D2fN-Md151435140,17862/75150170/176151/2″90654524-M14201938140/17862/75160175,181201/2″100755524-M14252542140/21462/91190180/214201/2″110856524-M14322950164/21475/91210215/243251/2″1301007834-M18403860164/24675/101230225/263301/2″1451108534-M18504870190/29591/112250248/274301/2″16012510034-M18656495210/295101/112270258/284451/2″18014512034/8-M188076118247/395112/139300300/326501/2″19016013538-M1810095140276/478127/176340315/370701″215/230180/190155/16038-M18/20125112/118175/195348/562159/206360375/440801″245/270210/220185/18838-M18/24150135/150210/260378/724176/228420428/500951″280/300240/250210/21838-M22/24)
