Bonnet Wowonjezera wa Cryogenic Globe Valve wa -196 ℃
✧ Kufotokozera
Mavavu a Cryogenic globe okhala ndi ma bonaneti otalikirapo opangidwa kuti azigwira ntchito pa kutentha kotsika mpaka -196 ° C amapangidwa mwapadera kuti athe kuthana ndi zovuta za cryogenic application.Boneti yowonjezera imapereka zowonjezera zowonjezera ndi chitetezo cha tsinde la valve ndi kulongedza kuti zitsimikizidwe kuti zikugwira ntchito bwino pa kutentha kotere.Ma valve awa amagwiritsidwa ntchito kwambiri m'mafakitale monga LNG (liquefied natural gas) processing, kupanga gasi m'mafakitale, ndi ntchito zina zogwirira ntchito za cryogenic fluid.Mfundo zazikuluzikulu za ma valve a cryogenic globe kwa -196 ° C akuphatikizapo:Zida: Mavavuwa amamangidwa pogwiritsa ntchito zipangizo zapadera. zomwe zingathe kusunga umphumphu ndi ntchito zawo m'madera a cryogenic.Zida zodziwika bwino zimaphatikizapo zitsulo zosapanga dzimbiri, zitsulo za carbon, ndi ma alloys ena omwe ali ndi kutentha kochepa kwambiri.Kusindikiza ndi Kuyika: Zida zosindikizira za valve ndi kulongedza ziyenera kupangidwa kuti zikhale zogwira mtima komanso zosinthika pa kutentha kochepa kwambiri kuti zisawonongeke ndikuzimitsa mwamphamvu. Kuyesa ndi Kutsata: Ma valve a Cryogenic globe chifukwa cha kutentha kotsika kotereku amayesedwa mwamphamvu kuti awonetsetse kuti akugwira ntchito komanso akutsatira miyezo yamakampani a cryogenic service.Insulation: Mapangidwe otalikirapo a bonnet amapereka kutchinjiriza kuteteza zigawo zofunika kuzizira kwambiri komanso kupewa kuopsa kwa ayezi komwe Zitha kulepheretsa ntchito ya valve.Ma valve awa ndi zigawo zofunika kwambiri poonetsetsa kuti chitetezo ndi chodalirika cha kayendedwe ka madzi a cryogenic.
✧ Mawonekedwe a Cryogenic Globe Valve Wowonjezera Bonnet wa -196 ℃
1. Boneti ya valve imapangidwa kuti ikhale yowonjezereka, yomwe ingathe kudzipatula kutengera kutentha kwa kutentha kwapang'onopang'ono, kuteteza chisindikizo cha chivundikirocho, ndikupangitsanso kuti valve ikhale yotseguka ndi kutseka mosavuta;
2. filler utenga kusinthasintha graphite kapena polytetrafluoroethylene ophatikizana dongosolo, ndi wabwino otsika kutentha kukana;
3. valavu yotsika kutentha imatenga dongosolo lotsegula dzenje la decompression pamphuno ya valve.Gasket utenga zosapanga dzimbiri zitsulo chikopa kopanira polytetrafluoroethylene kapena kusinthasintha graphite makhoma dongosolo;
4. pamene valavu yatsekedwa, pofuna kuteteza kutentha kwapakati mu chipinda cha valve kuti chisakwere chifukwa cha kutentha, zomwe zimapangitsa kuti pakhale kuwonjezereka kwachilendo, dongosolo lothandizira kupanikizika limaperekedwa kumbali yothamanga kwambiri ya chipata kapena thupi la valve;
5. Kusindikiza pamwamba pa valavu yomwe ili ndi cobalt-based cemented carbide, tungsten carbide pamapindikidwe otsika kutentha ndi yaying'ono, kuvala kukana, kungathe kusunga ntchito yabwino yosindikiza.
Chifukwa linanena bungwe la madzi otsika kutentha TV monga ethylene, madzi okosijeni, madzi wa hydrogen, liquefied gasi, liquefied mafuta ndi zinthu zina osati kuyaka ndi kuphulika, komanso gasification pamene Kutenthetsa mmwamba, ndi voliyumu kumawonjezera mazana nthawi pamene. mpweya.Zinthu za valve yotsika kutentha ndizofunika kwambiri, ndipo zinthuzo ndizosayenerera, zomwe zidzapangitse kutuluka kwakunja kapena kutuluka kwamkati kwa chipolopolo ndi kusindikiza pamwamba;The mabuku mawotchi katundu, mphamvu ndi chitsulo cha mbali sangathe kukwaniritsa zofunika ntchito kapena kuswa;Zomwe zimapangitsa kuti gasi wachilengedwe atayike chifukwa cha kuphulikako.Choncho, popanga, kupanga ndi kupanga ma valve otsika kutentha, chithandizo chakuthupi ndicho chofunikira kwambiri.
✧ Ubwino wa Cryogenic Globe Valve Wowonjezera Bonnet wa -196 ℃
Panthawi yotsegulira ndi kutseka kwa valve yachitsulo yopangidwa ndi zitsulo, chifukwa kukangana pakati pa diski ndi kusindikiza pamwamba pa thupi la valve ndi kochepa kuposa kwa valve yachipata, imakhala yosagwira ntchito.
Kutsegula kapena kutseka kwa tsinde la valve ndi kochepa, ndipo kumakhala ndi ntchito yodalirika yodulira, ndipo chifukwa kusintha kwa doko la mpando wa valve kuli kofanana ndi kugunda kwa valve disc, ndikoyenera kwambiri kusintha. wa mlingo wotuluka.Choncho, valavu yamtunduwu ndi yoyenera kwambiri kudulidwa kapena kuwongolera ndi kugwedeza.
