Emkhakheni wama-valve ezimbonini, ama-valve ebhola e-cryogenic afakwe phezulu abe yingxenye ebalulekile yokuphatha uketshezi lwe-cryogenic namagesi.Lawa ma-valve akhethekile aklanyelwe ukumelana namazinga okushisa abandayo futhi anikeze ukusebenza okuthembekile ezinhlelweni ze-cryogenic.Kule bhulogi, sizohlola izici eziyingqayizivele kanye nezinzuzo zama-valve ebhola afakwe phezulu e-cryogenic nokubaluleka kwawo ezinkambisweni ezihlukahlukene zezimboni.
Amavalvu ebhola afakwe phezulu e-Cryogenic aklanyelwe ukusebenza emazingeni okushisa afinyelela ku -196°C (-321°F).Lawa ma-valve avame ukusetshenziswa ezimbonini ezifana nowoyela negesi, i-petrochemical, imithi kanye ne-aerospace, lapho ukuphathwa kwegesi yemvelo ewuketshezi (LNG), i-nitrogen eyi-liquid kanye nolunye uketshezi lwe-cryogenic kuyingxenye ebalulekile yenqubo yokukhiqiza.
Enye yezinzuzo eziyinhloko zama-valve e-cryogenic top-loading ball yikhono lawo lokugcina ukuvala okuqinile kanye nophawu oluthembekile ngisho namazinga okushisa aphansi kakhulu.Lokhu kubalulekile ekuvimbeleni ukulahlekelwa uketshezi olubalulekile lwe-cryogenic nokuqinisekisa ukuphepha nokusebenza kahle kwemisebenzi yezimboni.I-top-entry design yalawa ma-valve ivumela ukufinyelela okulula ezingxenyeni zangaphakathi, okwenza ukugcinwa nokulungiswa kube lula, ikakhulukazi kuzinhlelo zokusebenza lapho i-valve ifakwe endaweni okunzima ukuyifinyelela.
Ukwengeza, ama-valve ebhola e-cryogenic afakwe phezulu enziwe ngezinto ezikhethiwe ngokukhethekile ukuze amelane nemiphumela yamazinga okushisa aphansi.Lezi zinto zihlanganisa insimbi engagqwali, i-carbon steel kanye nama-alloys akhethekile agcina izakhiwo zawo zemishini kanye nekhono lokuvala ezindaweni ze-cryogenic.Lokhu kuqinisekisa ukuphila isikhathi eside kwe-valve nokuthembeka ezinhlelweni ze-cryogenic.
Esinye isici esibalulekile se-cryogenic top-loading ball valves yikhono labo lokusingatha izimo ezicindezelayo neziphezulu.Lawa ma-valve aklanyelwe ukunikeza ukulawula okubushelelezi nokunembe kokugeleza koketshezi kanye negesi, okuwenza afanelekele izinqubo ezihlukahlukene zezimboni ezidinga ukulawulwa okunembile kwemidiya ye-cryogenic.Umklamo we-valve yebhola uphinde unikeze ukusebenza kwe-torque ephansi, ukunciphisa umzamo odingekayo wokuvula nokuvala i-valve, ngisho nasezimweni ezibandayo kakhulu.
Ngaphezu kwamakhono obuchwepheshe, ama-valve ebhola afakwe phezulu e-cryogenic aklanywe ngokuphepha engqondweni.Lawa ma-valve afakwe izinhlelo zokuvala ezithuthukisiwe kanye nezindlela zokusiza ukucindezela ukuvimbela ukuvuza nokuqinisekisa ubuqotho besistimu ngisho nasezimweni ezinzima kakhulu ze-cryogenic.Lokhu kubalulekile ekugcineni ukuphepha kwabasebenzi kanye nemishini ekusetshenzisweni kwe-cryogenic, njengoba izingozi ezingenzeka zokuphatha uketshezi lwe-cryogenic zibalulekile.
Sekukonke, izinzuzo zama-valve ebhola afakwe phezulu e-cryogenic awenza abe ingxenye ebalulekile ezinqubweni zezimboni ezibandakanya uketshezi lwe-cryogenic kanye nokubamba igesi.Ikhono labo lokumelana nezinga lokushisa elibanda kakhulu, ukugcina uphawu oluqinile, nokuhlinzeka ngokusebenza okuthembekile ngaphansi kwezimo ezicindezelayo kubenza babe yisinqumo sokuqala ezimbonini lapho izicelo ze-cryogenic ziyingxenye ebalulekile yokusebenza kwazo.
Ngamafuphi, ama-valve ebhola afakwe phezulu e-cryogenic adlala indima ebalulekile ekuqinisekiseni ukuphathwa okuphephile nokusebenza kahle koketshezi namagesi e-cryogenic ezindaweni ezihlukahlukene zezimboni.Izici zabo eziyingqayizivele kanye nezinzuzo zibenza babe yingxenye ebalulekile ekugcineni ubuqotho besistimu ye-cryogenic nokuthembeka.Njengoba ubuchwepheshe buqhubeka nokuthuthuka, isidingo samavalvu ebhola afakwe phezulu e-cryogenic kulindeleke ukuthi sikhule, siqinise ukubaluleka kwawo emkhakheni wezimboni.
