VSSJA(AF)型法兰松套伸缩接头名称：VSSJA(AF)型法兰松套伸缩接头性能特点法兰松套伸缩接头又称作法兰松套补偿接头、法兰松套伸缩节。法兰松套伸缩接头由本体、压盖、密封圈和紧固件组成，它采用和压盖松套伸缩接头相同的密封原理，连接方式一端为法兰连接，另一端为承插连接，适合阀门等设备与管道的连接。连接的同时能补偿管道的轴向位移及一定量的挠曲和偏心，从而保护阀门等设备。承插口同样适合与钢管、铸铁管、球墨铸铁管、PAC管、ABS管等连接。安装说明：法兰松套伸缩接头安装在管道上后，拧紧螺母弹性密封圈，在螺母压盖的作用下依靠相互斜度，紧压在管子外圈密封和连接作用。当温度变化时管子能在接头中间自由的伸缩，当地基下沉，管子能偏斜，并确保密封无渗漏，从而起到自动补偿之目的。VSSJA/AF型法兰松套伸缩接头主要性能参数公称通径DN管子插入长度Lo伸缩量8(mm)可挠量偏心量(mm)65-25065±2522300-70080±32.53800-3000130±6543200-4000140±705VSSJA/AF型法兰松套伸缩接头主要尺寸(PNO.250.61.OMPa)公称尺寸DN管子外径DW长度0.25Mpa法兰连接尺寸0.6Mpa1.OMpaL1LDKn-doDKn-doDKn-do65761051181601304-￠141601304-￠141851454-￠1880891901504-￠181901504-￠182001608-￠181OO1081232101702101702201801141251332402008-￠182402008-￠1825021O1401501592652252652252852408-￠2316820021932028032028034029525027313037533512-￠2337533512-61839535012-￠2330032513016044039512-￠1844039512-￠2244540035035549044549044550546016-￠2237740040654049516-￠2354049516-￠2256551516-￠2742645045759555059555016-￠2261556520-￠2648050050864560020-￠2364560020-￠2267062053060061075570520-￠2775570520-￠2678072520-￠3063070072086081024-￠2786081024-￠2689584024-￠3080082022025597592024-￠3097592024-￠30101595024-￠3390092010751020107510201115101528-￠33100010201175112028-￠301175112028-￠301230116028-￠36120012201375132032-￠301405134032-￠331455138032-￠39140014202701575152036-￠301630156036-￠361675159036-￠42160016201790173040-￠301830176040-￠361915182040-￠48180018201990193044-￠302045197044-￠402115202044-￠48200020202190213048-￠302265218048-￠422325223048-￠48220022202752405234052-￠332475239052-￠422550244052-￠56240024202605254056-￠332685260056-￠422760265056-￠56260026202403002805274060-￠332905281060-￠482960285060-￠56280028203030296064-￠363115302064-￠483180307064-￠56300030203230316068-￠363315322068-￠483405329068-￠60320032203430336072-￠363525343072-￠48---340034203630356076-￠363735364076-￠48---360036203840377080-￠363970386080-￠56---380038204045397080-￠40------400040204245417084-￠40------VSSJA/AF型法兰松套伸缩接头主要尺寸(PN1.62.54.0MPa)公称尺寸DN管子外径DW长度法兰连接尺寸1.6Mpa2.5Mpa4.0MpaL1LDKn-doDKn-d0DK11-do65761051181851454-￠181851458-￠181851458-￠1880892001608-￠182001602001601001081232201802351908-￠222351908-￠2211412513325021O2702208-￠262702208-￠261401501592852408-￠2330025030025016820021934029512-￠2336031012-￠2637532012-￠3025027313040535512-￠2742537012-￠3045038512-￠3330032513016046041O48543016-￠3051545016-￠3335035552047016-￠2655549016-￠3358051016-￠36377400406580
