Valavu Yowonjezera ya Cryogenic Globe ya -196℃
✧ Kufotokozera
Ma valve ozungulira a cryogenic okhala ndi maboni otalikira omwe amapangidwira kugwira ntchito kutentha kotsika mpaka -196°C amapangidwa mwapadera kuti azitha kugwira ntchito molimbika kwambiri pogwiritsa ntchito cryogenic. Boni yotalikirayo imapereka chitetezo chowonjezera komanso chitetezo cha tsinde la valve ndi kulongedza kuti zitsimikizire kuti zikugwira ntchito bwino kutentha kotsika koteroko. Ma valve awa amagwiritsidwa ntchito kwambiri m'mafakitale monga LNG (liquefied natural gas), kupanga gasi m'mafakitale, ndi ntchito zina zoyendetsera madzi a cryogenic. Mfundo zazikulu zofunika kuziganizira pa ma valve ozungulira a cryogenic a -196°C ndi izi: Zipangizo: Ma valve awa amapangidwa pogwiritsa ntchito zipangizo zapadera zomwe zingasunge umphumphu wawo ndi magwiridwe antchito m'malo ozungulira cryogenic. Zipangizo zodziwika bwino zimaphatikizapo chitsulo chosapanga dzimbiri, chitsulo cha kaboni, ndi zinthu zina zokhala ndi kutentha kochepa. Kutseka ndi Kuyika: Zigawo zotsekera ndi kuyika kwa valavu ziyenera kupangidwa kuti zikhale zogwira mtima komanso zosinthasintha kutentha kochepa kwambiri kuti zisatuluke ndikuzimitsa mwamphamvu. Kuyesa ndi Kutsatira Malamulo: Ma valve a cryogenic globe a kutentha kotsika kotere amayesedwa mwamphamvu kuti atsimikizire kuti akugwira ntchito bwino komanso kutsatira miyezo yamakampani yogwiritsira ntchito cryogenic. Kuteteza: Kapangidwe ka bonnet kotambasulidwa kamapereka chitetezo kuti ateteze zigawo zofunika ku kuzizira kwambiri komanso kupewa chiopsezo cha kupangika kwa ayezi komwe kungalepheretse kugwira ntchito kwa valavu. Ma valve awa ndi zigawo zofunika kwambiri pakuwonetsetsa kuti madzi a cryogenic akuyendetsedwa bwino komanso modalirika.
✧ Mbali za Cryogenic Globe Valve Extended Bonnet ya -196℃
1. Boneti ya valavu yapangidwa kuti iwonjezere kapangidwe ka boneti, komwe kumatha kusiyanitsa mphamvu ya zinthu zotentha kwambiri pa kulongedza, kuletsa kugwira ntchito kwa chivundikiro cha chivundikiro, komanso kupangitsa valavu kutseguka ndi kutseka mosavuta;
2. Chodzazacho chimagwiritsa ntchito kapangidwe kosinthasintha ka graphite kapena polytetrafluoroethylene, kokhala ndi kukana kutentha kochepa;
3. Valavu yotsika kutentha imagwiritsa ntchito kapangidwe ka kutsegula dzenje lotsegula pakati pa valavu. Gasket imagwiritsa ntchito chikopa chachitsulo chosapanga dzimbiri chopangidwa ndi polytetrafluoroethylene kapena kapangidwe kosinthasintha ka graphite;
4. valavu ikatsekedwa, kuti kutentha kochepa m'chipinda cha valavu kusakwere chifukwa cha kutentha, zomwe zimapangitsa kuti kuthamanga kwa magazi kukwere kwambiri, kapangidwe kake kamene kamathandizira kuthamanga kwa magazi kamaperekedwa kumbali ya kuthamanga kwa magazi kwa chipata kapena thupi la valavu;
5. Kutseka pamwamba pa valavu yopangidwa ndi cobalt-based simenti carbide, tungsten carbide pa kutentha kochepa ndi yaying'ono, kukana kuvala, kumatha kusunga magwiridwe antchito abwino otseka.
Chifukwa kutulutsa kwa zinthu zotentha pang'ono monga ethylene, mpweya wamadzimadzi, haidrojeni yamadzimadzi, mpweya wachilengedwe wosungunuka, mafuta osungunuka ndi zinthu zina sikuti zimangoyaka komanso kuphulika, komanso zimawonjezera mpweya ukatenthedwa, ndipo kuchuluka kwake kumawonjezeka nthawi zambiri pamene mpweya umasungunuka. Zipangizo za valavu yotsika kwambiri ndizofunikira kwambiri, ndipo zinthuzo sizoyenera, zomwe zingayambitse kutuluka kwakunja kapena kutuluka kwamkati kwa chipolopolo ndi pamwamba potseka; Kapangidwe ka makina, mphamvu ndi chitsulo cha ziwalo sizingakwaniritse zofunikira zogwiritsidwa ntchito kapena kusweka; Zimapangitsa kuti mpweya wachilengedwe wosungunuka utuluke chifukwa cha kuphulika. Chifukwa chake, popanga, kupanga ndi kupanga mavalavu otsika kutentha, kukonza zinthu ndiye vuto lalikulu.
✧ Ubwino wa Cryogenic Globe Valve Extended Bonnet ya -196℃
Pakutsegula ndi kutseka valavu yachitsulo chopangidwa ndi chitsulo, chifukwa kukangana pakati pa diski ndi pamwamba pa valavu kumakhala kochepa kuposa kwa valavu ya chipata, sikutha kusweka.
Kutsekeka kapena kutseka kwa tsinde la valavu ndi kochepa, ndipo kuli ndi ntchito yodalirika yodulira, ndipo chifukwa kusintha kwa doko la mpando wa valavu kumafanana ndi kutsekeka kwa diski ya valavu, ndikoyenera kwambiri kusintha kuchuluka kwa madzi. Chifukwa chake, valavu yamtunduwu ndi yoyenera kwambiri kudula kapena kulamulira ndi kugwedeza.
