Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa) – I-Cryogenic Globe Valve (-196°C)
U: Uyini umehluko phakathi kwevalvu yeglobe e-cryogenic nevalvu yeglobe ejwayelekile?
A: Ama-valve e-cryogenic globe anezici eziningana ezibalulekile ezingatholakali kuma-valve ajwayelekile: i-bonnet enwetshiwe ene-drip plate ukuvikela izivalo zesiqu; ukwelashwa okujulile kwe-cryogenic kwazo zonke izingxenye; izinto ezikhethekile zesihlalo (PCTFE, PEEK) zokushisa okuphansi; ukupakisha okuphansi kokukhishwa kwe-fugie; kanye nokuhlolwa kokusebenza kwe-cryogenic okuphoqelekile ngokwe-BS 6364.
Q: Lingakanani izinga lokushisa eliphansi lesevisi yama-valve akho e-cryogenic globe?
A: Ama-valve ethu ajwayelekile e-cryogenic globe alinganiselwe isevisi engu--196°C nge-BS 6364. Ngesevisi ye-hydrogen ewuketshezi (-253°C) noma i-helium ewuketshezi (-269°C), sinikeza imiklamo ekhethekile.
U: Kuyini ukwelashwa okujulile kwe-cryogenic futhi kungani kudingeka?
A: Ukwelashwa okujulile kwe-cryogenic inqubo yokupholisa izingxenye ze-valve zibe yi--196°C okungenani amahora ayi-8. Lokhu kuguqula i-austenite egciniwe, kunciphisa ukucindezeleka okusele, futhi kuqinisekisa ukuzinza kobukhulu ekushiseni kwesevisi.
Q: Yiziphi izinto zesihlalo ozincomayo zesevisi ye--196°C?
A: Ngensizakalo ye--196°C, sincoma i-PCTFE njengezinto eziyinhloko zesihlalo. I-PCTFE igcina izakhiwo zayo zomshini futhi inikeza ukuvala okuhle kakhulu emazingeni okushisa acwebezelayo.
U: Ingabe ukuhlolwa kokusebenza kwe-cryogenic kuyimpoqo?
A: Ngokwe-BS 6364 kanye ne-ISO 28921-1, ukuhlolwa kokusebenza kwe-cryogenic kuyimpoqo kuma-valve asetshenziswa ku-LNG kanye nesevisi ye-cryogenic. I-Womic yenza ukuhlolwa kokusebenza kwe-cryogenic okungu-100%.
U: Ingabe ninikeza uphawu lwe-bellows uma kungekho ukuvuza kwezicelo?
A: Yebo. Ngezinhlelo zokusebenza ezibalulekile ezidinga ukuvuza kwesiqu okungaphelele (njengoketshezi oluyingozi noma olubizayo), sinikeza umklamo wesivalo se-bellows onesihlalo sangemuva sesibili.

Ukusetshenziswa:Ukulawulwa kokukhishwa nokugcinwa komkhiqizo we-nitrogen ewuketshezi (-196°C) kanye nomoya-mpilo owuketshezi (-183°C). Ukucindezela komklamo: 5.0 MPa. Ibhonethi enwetshiwe enepuleti lokuconsa, esebenza ngesondo lesandla.
Izinselele Zobuchwepheshe Nezixazululo:
1. Ukulawula ukugeleza okunembile ku--196°C ukuze umkhiqizo uhlanzekeIzidingo zokuhlanzeka komkhiqizo we-ASU (99.999% wezinga likagesi) zidinga ukulawulwa okunembile kokugeleza. Ama-valve e-globe ahlinzekwa yi-Womic anezihlalo ze-PCTFE nama-disc e-Stellite aqinile ukuze kube nezici zokucindezela ezizinzile. Wonke ama-valve angu-120 aphumelele ukuhlolwa kwe-cryogenic ngaphandle kokuvuza nhlobo.
2. Ukwelashwa okujulile kwe-cryogenic kwemizimba ye-CF3M eyenziwe nge-castImizimba ye-CF3M ehlanganisiwe isengozini yokuthola i-austenite egciniwe. I-Womic yenze ukwelashwa okujulile kwe-cryogenic kwemijikelezo emithathu (ukucwiliswa -196°C, amahora angu-12 ngomjikelezo ngamunye). Ukuhlolwa kabusha kobukhulu kuqinisekisile ukuthi akukho ukuphambuka.
3. Ukupakisha ukukhishwa komoya-mpilo okuphansi okusabalele ukuze kuhlinzekwe nge-oxygenIsevisi ye-oksijini idinga ukuhlanzeka okuqinile kanye nokupakisha ukukhishwa komoya okuphansi. I-Womic ihlinzeka nge-ISO 15848-1 Class A packing enezithambisi ezihambisana nomoya-mpilo.
4. Ukuhlolwa komuntu wesithathu yi-BVIklayenti lidinga ukuhlolwa yi-Bureau Veritas. I-BV ikhiphe izitifiketi zingakapheli izinsuku eziyi-10.
Umphumela:Ukwandiswa kwe-ASU kuqaliswe ngempumelelo. Wonke ama-valve e-globe angu-120 e-cryogenic asebenze ku--196°C isikhathi esingaphezu kwezinyanga ezingu-18 ngaphandle kwezehlakalo zokulungiswa.
