BF（VSSJA-1）型单法兰松套限位伸缩接头是在松套伸缩接头原有性能的基础上增设限位装置，在最大伸缩量处用双螺母锁定。管道在允许的伸缩量中可以自由伸缩，一旦超过其最大伸缩量就起到限位，确保管道的安全运行，特别适用于振动或有一定斜度及拐弯的管路中的连接。该产品适用于一边与法兰连接，一边与管道焊接，安装时调整产品两端与管道或法兰的安装长度，对角依次均匀拧紧压盖螺栓，再调整好限位螺母，这样就能让管道在伸缩量范围内可以自由伸缩，缩定伸缩量，确保管道的安全运行。产品规格：DN50-DN4000公称压力：PN0.6Mpa-PN2.5MPa材质：球墨铸铁（QT400-15）、钢制（Q235）执行标准：GB/T12465-2002PN0.61.0MPa的BF型单法兰松套限位伸缩接头的主要尺寸公称通径DN管子外径DW外形尺寸L伸缩量δ法兰连接尺寸0.6MPa1.0MPaDD1n-dODD1n-dO6576340501601304-Φ141851454-Φ1880891901504-Φ182001608-Φ181001082101702201801141251332402008-Φ182502101401501592652252852408-Φ2216820021932028034029525027337533512-Φ1839535012-Φ223003253506544039512-Φ2244540035037749044550546016-Φ2240042654049516-Φ2256551516-Φ2645048059555061556520-Φ2650053064560020-Φ2267062060063075570520-Φ2678072520-Φ3070072086081024-Φ2689584024-Φ3080082059013097592024-Φ30101595024-Φ33900920107510201115105028-Φ33100010201175112028-Φ301230116028-Φ36120012201405134032-Φ331455138032-Φ39140014201603156036-Φ361675159036-Φ42150015201730166017851700160016201830176040-Φ361915182040-Φ48180018202045197044-Φ392115202044-Φ48200020202265218048-Φ422325223048-Φ48220022202475239052-Φ422550244052-Φ56240024202685260056-Φ422760265056-Φ56260026206001502905281060-Φ482960285060-Φ56280028203115302064-Φ483180307064-Φ56300030203315322068-Φ483405329068-Φ62320032203525343072-Φ48///340034203735364076-Φ48///360036203970386080-Φ56///PN1.62.5MPa的BF型单法兰松套限位伸缩接头的主要尺寸公称通径DN管子外径DW外形尺寸L伸缩量δ法兰连接尺寸1.6MPa2.5MPaDD1n-dODD1n-dO6576340501851454-Φ181851458-Φ1880892001608-Φ182001601001082201802351908-Φ221141251332502102702208-Φ261401501592852408-Φ2230025016820021934029536031012-Φ2625027340535512-Φ2242537012-Φ303003253506546041048543016-Φ3035037752047016-Φ2255549016-Φ3340042658052516-Φ2662055016-Φ3645048064058520-Φ2667060020-Φ3650053071565073066060063084077020-Φ3084577020-Φ3970072091084024-Φ3096087524-Φ42800820590130102595024-Φ33108599024-Φ489009201125105028-Φ331185109028-Φ48100010201255117028-Φ361320121028-Φ56120012201485139032-Φ391530142032-Φ56140014201685159036-Φ4240-Φ481755164032-Φ6216001620193018201975186040-Φ62180018202130202044-Φ482195207044-Φ70200020202345223048-Φ482425230048-Φ70220022202555244052-Φ56240024202765265056-Φ56)
