Mafunso Ofunsidwa Kawirikawiri (Mafunso Ofunsidwa Kawirikawiri) - Cryogenic Globe Valve (-196°C)
Q: Kodi kusiyana pakati pa valavu ya cryogenic globe ndi valavu ya globe yokhazikika ndi kotani?
Yankho: Ma valve a cryogenic globe ali ndi zinthu zingapo zofunika zomwe sizipezeka mu ma valve wamba: bonnet yotambasulidwa yokhala ndi mbale yothira madzi kuti iteteze zisindikizo za tsinde; chithandizo cha cryogenic cha zigawo zonse; zipangizo zapadera za mipando (PCTFE, PEEK) kuti zitsimikizire kutentha kochepa; kulongedza mpweya wochepa; ndi kuyesa kofunikira kwa cryogenic malinga ndi BS 6364.
Q: Kodi kutentha kochepa kwambiri kwa ma valve anu a cryogenic globe ndi kotani?
A: Ma valve athu odziwika bwino a cryogenic globe amayesedwa kuti agwire ntchito ya -196°C pa BS 6364. Pa ntchito ya hydrogen yamadzimadzi (-253°C) kapena helium yamadzimadzi (-269°C), timapereka mapangidwe apadera.
Q: Kodi chithandizo cha deep cryogenic n'chiyani ndipo n'chifukwa chiyani chikufunika?
A: Chithandizo cha cryogenic kwambiri ndi njira yoziziritsira zigawo za valavu kufika pa -196°C kwa maola osachepera 8. Izi zimasintha austenite yosungidwa, zimachepetsa kupsinjika kotsala, ndikutsimikizira kukhazikika kwa gawo pa kutentha kwa ntchito.
Q: Ndi zipangizo ziti za mipando zomwe mumalimbikitsa pa ntchito ya -196°C?
A: Pa ntchito ya -196°C, tikupangira PCTFE ngati chinthu chachikulu chopachikirapo. PCTFE imasunga mawonekedwe ake amakina ndipo imapereka kutseka bwino kwambiri kutentha kwa cryogenic.
Q: Kodi kuyezetsa magwiridwe antchito a cryogenic ndikofunikira?
A: Malinga ndi BS 6364 ndi ISO 28921-1, kuyesa magwiridwe antchito a cryogenic ndikofunikira pa ma valve omwe amagwiritsidwa ntchito mu LNG ndi ntchito ya cryogenic. Womic amachita mayeso 100% a cryogenic performance.
Q: Kodi mumapereka chisindikizo cha bellows ngati palibe kutayikira kwa madzi?
A: Inde. Pa ntchito zofunika kwambiri zomwe sizikufuna kuti tsinde lituluke (monga madzi oopsa kapena okwera mtengo), timapereka kapangidwe ka chisindikizo cha bellows chokhala ndi mpando wina wakumbuyo.
Q: Kodi nthawi yodziwika bwino yogwiritsira ntchito ma valve a cryogenic globe ndi iti?
A: Nthawi yokhazikika yoperekera chithandizo ndi masabata 8-12 pakusintha kwanthawi zonse. Pa kukula kwakukulu (> 12") kapena zipangizo zapadera, nthawi yoperekera chithandizo ndi masabata 12-16.

Kagwiritsidwe:Nayitrogeni yamadzimadzi (-196°C) ndi mpweya wamadzimadzi (-183°C) yowongolera ndi kusungira zinthu. Kupanikizika kwa kapangidwe: 5.0 MPa. Boneti yotambasulidwa yokhala ndi mbale yothira madzi, yoyendetsedwa ndi gudumu lamanja.
Mavuto ndi Mayankho a Ukadaulo:
1. Kuwongolera bwino kayendedwe ka madzi pa -196°C kuti zinthu zikhale zoyeraZofunikira pa kuyera kwa zinthu za ASU (99.999% pa kalasi yamagetsi) zimafuna kuwongolera kolondola kwa kayendedwe ka madzi. Ma valve opangidwa ndi Womic okhala ndi mipando ya PCTFE ndi ma disc olimba a Stellite kuti azitha kukhazikika bwino. Ma valve onse 120 adapambana mayeso a cryogenic ndipo palibe kutuluka kwa madzi.
2. Chithandizo cha cryogenic cha matupi a CF3M omwe adapangidwaMatupi a CF3M omwe ali ndi kachilomboka amatha kugwidwa ndi austenite yosungidwa. Womic adachita chithandizo cha cryogenic cha magawo atatu (-196°C, maola 12 pa nthawi iliyonse). Kuyang'anitsitsanso kwa miyeso kunatsimikizira kuti palibe kusokonekera.
3. Kulongedza mpweya wochepa wotulutsa mpweya woipa kuti uthandize pa ntchito ya okosijeniUtumiki wa okosijeni umafuna ukhondo wokhwima komanso kulongedza mpweya woipa pang'ono. Womic yaperekedwa ndi ISO 15848-1 Class A packing yokhala ndi mafuta ogwirizana ndi mpweya.
4. Kuyang'aniridwa ndi BV ndi chipani chachitatuKasitomala amafunika kuyesedwa ndi Bureau Veritas. BV idapereka satifiketi mkati mwa masiku 10.
Zotsatira:Kukulitsa kwa ASU kwayamba bwino. Ma valve onse 120 a cryogenic globe akhala akugwira ntchito pa -196°C kwa miyezi yoposa 18 popanda zochitika zokonza.
