Kwintsimi yee-valve zoshishino, iivalve zebhola ze-cryogenic eziphezulu ziye zaba yinto ebalulekileyo yokuphatha i-cryogenic fluids kunye neegesi.Ezi zivalo ezikhethekileyo zenzelwe ukujamelana namaqondo okushisa abandayo kwaye zinikeze ukusebenza okuthembekileyo kwizicelo ze-cryogenic.Kule bhulogi, siza kuphonononga iimpawu ezikhethekileyo kunye neenzuzo ze-valve zebhola ze-cryogenic eziphezulu kunye nokubaluleka kwazo kwiinkqubo ezahlukeneyo zoshishino.
Iivalve zebhola ze-Cryogenic eziphezulu zenzelwe ukusebenza kumaqondo obushushu asezantsi -196 ° C (-321 ° F).Ezi zivalo zisetyenziswa ngokuqhelekileyo kumashishini afana neoli kunye negesi, i-petrochemical, i-pharmaceutical kunye ne-aerospace, apho ukuphathwa kwe-liquefied natural gas (LNG), i-nitrogen engamanzi kunye nezinye ii-cryogenic fluids ziyinxalenye ebalulekileyo yenkqubo yokuvelisa.
Enye yeenzuzo eziphambili ze-cryogenic top-loading ball valves kukukwazi kwabo ukugcina ukuvalwa okuqinileyo kunye nesitywina esithembekileyo nakwiqondo lokushisa eliphantsi kakhulu.Oku kubalulekile ekuthinteleni ukulahleka kwexabiso le-cryogenic fluids kunye nokuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwemisebenzi yoshishino.Uyilo oluphezulu lwale valve luvumela ukufikelela lula kumacandelo angaphakathi, okwenza ukugcinwa kunye nokulungiswa kube lula ngakumbi, ngakumbi kwizicelo apho i-valve ifakwe kwindawo enzima ukufikelela kuyo.
Ukongezelela, iivalve zebhola ze-cryogenic eziphezulu zenziwe kwizinto ezikhethiweyo ezikhethiweyo ukumelana nemiphumo yokushisa okuphantsi.Ezi zixhobo ziquka insimbi engenasici, i-carbon steel kunye ne-specialty alloys egcina iimpawu zabo zomatshini kunye nokukwazi ukutywina kwiindawo ze-cryogenic.Oku kuqinisekisa ubude be-valve kunye nokuthembeka kwizicelo ze-cryogenic.
Olunye uphawu olubalulekileyo lwe-cryogenic top-loading ball valves kukukwazi kwabo ukuphatha uxinzelelo oluphezulu kunye neemeko ezihamba phambili.Ezi zivalo zenzelwe ukubonelela ngolawulo olugudileyo kunye noluchanekileyo lokuhamba kwamanzi kunye negesi, okwenza kube lula kwiinkqubo ezahlukeneyo zoshishino ezifuna ukulawulwa ngokuchanekileyo kwemidiya ye-cryogenic.Uyilo lwevalve yebhola lukwabonelela ngokusebenza kwetorque ephantsi, ukunciphisa umgudu ofunekayo wokuvula nokuvala ivalve, nakwimeko ezibanda kakhulu.
Ukongeza kwizakhono zobugcisa, iivalve zebhola ze-cryogenic eziphezulu zenzelwe ukhuseleko engqondweni.Ezi zivalo zixhotyiswe ngeenkqubo zokutywina eziphambili kunye neendlela zokunciphisa uxinzelelo ukukhusela ukuvuza kunye nokuqinisekisa ukunyaniseka kwenkqubo nakwiimeko ezinzima kakhulu ze-cryogenic.Oku kubalulekile ekugcineni ukhuseleko lwabasebenzi kunye nezixhobo kwizicelo ze-cryogenic, njengoko iingozi ezinokubakho zokuphatha i-cryogenic fluids zibalulekile.
Ngokubanzi, izibonelelo ze-cryogenic ze-valve zebhola ezixhonywe phezulu zizenza zibe yinxalenye ebalulekileyo kwiinkqubo zoshishino ezibandakanya i-cryogenic fluid kunye nokuphathwa kwegesi.Ukukwazi kwabo ukujamelana namaqondo okushisa abandayo, ukugcina isitywina esiqinileyo, kunye nokubonelela ngokusebenza okuthembekileyo phantsi kweemeko eziphezulu zoxinzelelo kubenza ukuba bakhethe kuqala kumashishini apho izicelo ze-cryogenic ziyingxenye ebalulekileyo yokusebenza kwazo.
Isishwankathelo, iivalve zebhola ze-cryogenic eziphezulu zidlala indima ebalulekileyo ekuqinisekiseni ukugcinwa ngokukhuselekileyo kunye nokuphathwa ngokufanelekileyo kwe-cryogenic fluids kunye neegesi kwiindawo ezahlukeneyo zoshishino.Iimpawu zabo ezikhethekileyo kunye neenzuzo zenza ukuba zibe yinto ebalulekileyo ekugcineni ukunyaniseka kwenkqubo ye-cryogenic kunye nokuthembeka.Njengoko itekhnoloji iqhubela phambili, imfuno yeevalvu zebhola ezixhonywe phezulu i-cryogenic kulindeleke ukuba ikhule, iqinise ngakumbi ukubaluleka kwayo kwicandelo leshishini.
