Ama-valve ebhola e-Cryogenic anamabhonethi anwetshiwe afanele ukusebenza emazingeni okushisa afinyelela ku -196°C aklanyelwe ngokukhethekile ukuphatha izimo ezimbi kakhulu zezicelo ze-cryogenic.Lawa mavalvu asetshenziswa kakhulu ezimbonini ezifana ne-LNG (igesi yemvelo ewuketshezi), ukukhiqizwa kwegesi yezimboni, nezinye izinhlelo zokusebenza zokubamba uketshezi lwe-cryogenic.Izici ezibalulekile zamavalvu ebhola e-cryogenic anamabhonethi anwetshiwe angu-196°C ahlanganisa:Izisetshenziswa Ezisezingeni Eliphansi: The ama-valve ngokuvamile akhiwa ngezinto ezikhethekile ezifana nensimbi engagqwali, i-carbon steel, noma amanye ama-alloys anezakhiwo ezisezingeni eliphansi lokushisa ukuze kuqinisekiswe ukusebenza nobuqotho endaweni ye-cryogenic.Idizayini Yebhonethi Enwetshiwe: Ibhonethi enwetshiwe inikeza ukufakwa nokuvikela okwengeziwe kwesiqu se-valve nokupakishwa. ukugcina ukusebenza kahle emazingeni okushisa aphansi kakhulu.Ukuvalwa Nokupakishwa: Izingxenye zokuvala kanye nokupakishwa kwe-valve kuklanyelwe ngokukhethekile ukuthi zihlale zisebenza kahle futhi ziguquguquke emazingeni okushisa e-cryogenic, okuvumela ukuvala okuqinile futhi kuvimbele ukuvuza.Ukuhlola Nokuhambisana: Lawa mavalvu ahlolwa kanzima ukuze qinisekisa ukusebenza nokuhambisana nezindinganiso zezimboni zesevisi ye-cryogenic.Ukuphepha Kokusebenza: Ama-valve ebhola e-cryogenic anamabhonethi anwetshiwe abalulekile ekugcineni ukulawulwa okuphephile nokuthembekile kokugeleza koketshezi lwe-cryogenic, okunomthelela ekuphepheni kokusebenza ezinhlelweni ze-cryogenic.Lapho ukhetha ama-valve ebhola e-cryogenic ka--196° C, kubalulekile ukucabangela izici ezifana nokuhambisana kwezinto, ingcindezi nezinga lokushisa, nokuhambisana nezindinganiso nemithetho yemboni efanelekile.
I-API 6D trunnion ball valve iwumkhiqizo wevalvu webhola ohlangabezana nezimfuneko ze-American Petroleum Institute standard API 6D.Leli zinga libeka umklamo, izinto, ukukhiqiza, ukuhlolwa, ukufakwa kanye nezidingo zokunakekelwa kwamavalvu ebhola e-API 6D ukuze kuqinisekiswe ikhwalithi nokuthembeka kwamavalvu ebhola, futhi ifanele izinkundla ezihlukahlukene zezimboni ezifana nowoyela negesi.Izici ze-API 6D trunnion ball valve zihlanganisa:
I-1.Ibhola eligcwele eligcwele lisetshenziselwa ukunciphisa ukwehla kokucindezela kwe-valve nokuthuthukisa umthamo wokugeleza.
2.I-valve ithatha isakhiwo sokuvala esinezinhlangothi ezimbili esisebenza kahle sokuvala.
I-3.I-valve kulula ukuyisebenzisa futhi ibushelelezi, futhi isibambo simakwe ukuze sibonakale kalula ngu-opharetha.
I-4.Isihlalo se-valve kanye nendandatho yokufaka uphawu yenziwe ngezinto zokushisa eziphezulu, ezicindezelayo kanye ne-corrosion-resistant, ezifanele imidiya ehlukahlukene yamanzi.
5. Izingxenye ze-valve yebhola zihlukaniswa kahle, kulula ukuzifaka nokuyinakekela.Amavalvu ebhola e-API 6D afanele izikhathi emkhakheni wezimboni ezidinga ukulawula ukugeleza koketshezi, ukunqamula uketshezi, nokugcina ukuqina kwengcindezi, njengamasistimu amapayipi oketshezi ku-petroleum, amakhemikhali, igesi yemvelo, ukwelashwa kwamanzi neminye imikhakha.

Isevisi yokuthengisa emva kokuthengisa ye-valve yebhola elintantayo ibaluleke kakhulu, ngoba isevisi efika ngesikhathi futhi ephumelelayo ngemva kokuthengisa ingaqinisekisa ukusebenza kwayo kwesikhathi eside nokuzinzile.Okulandelayo okuqukethwe kwesevisi yangemuva kokuthengisa kwamanye ama-valve amabhola antantayo:
1.Ukufakwa kanye nokugunyazwa: Abasebenzi besevisi yangemuva kokuthengisa bazoya kusayithi ukuze bafake futhi balungise iphutha le-valve yebhola elintantayo ukuze baqinisekise ukusebenza kwayo okuzinzile nokujwayelekile.
I-2.Ukugcinwa: Gcina njalo i-valve yebhola elintantayo ukuze uqinisekise ukuthi isesimweni esihle kakhulu sokusebenza futhi unciphise izinga lokuhluleka.
3.Ukuxazulula inkinga: Uma i-valve yebhola elintantayo ihluleka, izisebenzi zesevisi yangemuva kokuthengisa zizokwenza ukuxazulula inkinga endaweni ngesikhathi esifushane kakhulu ukuze kuqinisekiswe ukusebenza kwayo okuvamile.
4.Ukuvuselelwa nokuthuthukiswa komkhiqizo: Ngokuphendula ezintweni ezintsha kanye nobuchwepheshe obusha obuvela emakethe, abasebenzi besevisi yangemuva kokuthengisa bazoncoma ngokushesha ukuvuselela nokuthuthukisa izixazululo kumakhasimende ukuze bawanikeze imikhiqizo yamavalvu engcono.
5. Ukuqeqeshwa kolwazi: Izisebenzi zesevisi yangemuva kokuthengisa zizohlinzeka ngokuqeqeshwa kolwazi lwama-valve kubasebenzisi ukuze kuthuthukiswe izinga lokuphatha nokunakekela abasebenzisi besebenzisa ama-valve amabhola antantayo.Ngamafuphi, isevisi yangemuva kokuthengisa ye-valve yebhola elintantayo kufanele iqinisekiswe kuzo zonke izinkomba.Kungale ndlela kuphela engaletha abasebenzisi umuzwa ongcono nokuphepha kokuthenga.
