Kodi chimachitika ndi chiyani mavavu akumafakitale akakumana ndi mikhalidwe yoipitsitsa—kaya ndi kutentha kochepera paziro m’magasi achilengedwe opangidwa ndi liquefied kapena kutentha m’mapaipi a nthunzi? Yankho lagona mu uinjiniya wapadera wa ma valve. Kusankha mtundu woyenerera wa vavu chifukwa cha kutentha kwambiri sikungokhudza magwiridwe antchito-komanso chitetezo, moyo wautali, komanso magwiridwe antchito.
M'nkhaniyi, tikufufuza kusiyana kwaumisiri pakati pa ma valve a cryogenic ndi ma valve otentha kwambiri, kuwonetsa malingaliro a mapangidwe, kusankha zinthu, teknoloji yosindikiza, ndi momwe mungatsimikizire kudalirika pansi pa kupsinjika kwa kutentha.
Kutentha Kumafuna Mapangidwe a Valve Yamawonekedwe
Mavavu omwe amagwira ntchito kuzizira kwambiri kapena kutentha kwambiri ayenera kukonzedwa kuti athe kupirira kusintha kwakuthupi komwe kumachitika m'malo awo antchito.
Mavavu a cryogenic, omwe amagwiritsidwa ntchito pophatikizira mipweya yamadzimadzi ngati LNG kapena okosijeni wamadzimadzi, amagwira ntchito potentha mpaka -196 ° C. Pakutentha kotereku, zida zimakhala zolimba, ndipo ngakhale kudontha kwakung'ono kumatha kuyambitsa ngozi. Mavavuwa ayenera kupangidwa ndi ma bonnet otalikirapo kuti atseke tsinde ku zozizira komanso kupewa kuzizira kapena kugwidwa.
Mosiyana ndi zimenezi, ma valve otenthetsera kwambiri amapangidwa kuti azigwira ntchito pansi pa kutentha kosalekeza—nthawi zambiri kupitirira 400°C. Izi zimagwiritsidwa ntchito kwambiri m'mafakitale opangira magetsi, zoyenga, komanso makina othamanga kwambiri. Apa, vuto lagona pakukulitsa matenthedwe, makutidwe ndi okosijeni, ndi kusunga torque yosasinthika ndi mphamvu yosindikiza.
Kusankha Zinthu: Kukhalitsa Pansi Monyanyira
Kusankha zinthu zoyenera ndizofunikira pazitsulo zonse za cryogenic ndi kutentha kwambiri.
Kwa ma valve a cryogenic, zitsulo zosapanga dzimbiri ndi nickel alloys amagwiritsidwa ntchito kawirikawiri chifukwa cha kulimba kwawo komanso kukhazikika kwapangidwe pa kutentha kochepa. Zidazi zimakana kusweka ndi kusunga katundu wawo wosindikiza ngakhale zitakhala ndi kuzizira kofulumira.
Kumbali ina, ma valve okwera kwambiri amafunikira zipangizo zomwe zimatsutsana ndi kutentha kwa kutentha, monga chrome-molybdenum steel kapena Inconel. Zitsulozi zimapereka mphamvu zosungirako bwino komanso kukana dzimbiri pakutentha kokwera, komwe kuyendetsa njinga kungayambitse kutopa komanso kutayikira.
Kusindikiza Technologies: Kulondola Ndikofunikira
Kusindikiza koyenera ndikofunikira kuti ma valve agwire pa kutentha kulikonse, koma malo owopsa amabweretsa zovuta zapadera.
Mavavu a cryogenic nthawi zambiri amagwiritsa ntchito zida zosindikizira zofewa monga PTFE kapena ma elastomer apadera omwe amakhala osinthika pakatentha kwambiri. Zisindikizozi zimayenera kulolera kutsekeka ndikuchepetsa njira zotayikira ngakhale madzi oundana adutsa mu valve.
Ma valve okwera kwambiri, komabe, amadalira kwambiri zitsulo zokhala ndi zitsulo zokhala ndi zitsulo ndi graphite-based packing zipangizo zomwe zimatsutsa kuwonongeka m'madera otentha. Cholinga chake ndikuletsa kuphulika ndikuwonetsetsa kusindikiza kukhulupirika ngakhale kuwonjezereka kwa kutentha komanso kupanikizika kwakukulu kwamkati.
Kuwonetsetsa Kudalirika Kwa Nthawi Yaitali Pamikhalidwe Yambiri
Kuti mukhalebe okhazikika komanso otetezeka m'malo otentha kwambiri, njira zingapo zaumisiri ndizofunikira:
Kulipiridwa kwa Matenthedwe: Zomwe zimapangidwa monga ma bonaneti otalikirapo, kulongedza zodzaza ndi moyo, ndi mapangidwe osinthika a mipando amathandizira kuyamwa kukula kapena kutsika ndikuchepetsa kupsinjika kwa ma valve.
Kuyesa Kwambiri: Mavavu ayenera kuyesedwa kachitidwe ka cryogenic kapena kutentha kwambiri, kuphatikiza kuzindikira kutayikira kwa helium, kuyezetsa njinga zamoto, komanso kuyesa kutayikira kwa mipando.
Kuyika ndi Kusamalira Moyenera: Ngakhale ma valve opangidwa bwino kwambiri amatha kulephera popanda kuwongolera bwino. Oyikapo akuyenera kutsatira malangizo a torque, njira zabwino zotsekera, komanso kukonza zoyendera pafupipafupi, makamaka pamakina okwera njinga.
Sankhani Smart for Harsh Conditions
Kaya mukuyang'anira malo osungiramo cryogenic kapena mukuyang'anira malo opangira magetsi otentha, mavavu omwe mumawasankha amakhudza kwambiri chitetezo ndi magwiridwe antchito. Pomvetsetsa zofunikira zenizeni za ma valve a cryogenic ndi ma valve otentha kwambiri, mukhoza kugwirizanitsa bwino njira zothetsera ntchito yanu ndikuchepetsa chiopsezo cha nthawi yaitali.
Valve ya Taikeimakhazikika pamavavu olimba, opangidwa mwaluso kwambiri m'malo ovuta kwambiri. Lumikizanani nafe lero kuti tifufuze mayankho athu ndikuwonetsetsa kuti makina anu akugwira ntchito modalirika-zilibe kutentha.
