Xa kuziwa kwiivalve zoshishino, iivalve zebhola zokulayisha phezulu ziyinxalenye ebalulekileyo kwizicelo ezininzi. Olu hlobo lwevalve luyaziwa ngokuthembeka, ukuqina, kunye nokuguquguquka, oko kuyenza ibe lukhetho oludumileyo kuwo wonke amashishini ahlukeneyo. Kwesi sikhokelo sibanzi, siza kujonga nzulu kwiimpawu eziphambili, izibonelelo, kunye nokusetyenziswa kwevalvu yebhola yofikelelo oluphezulu.
Iimpawu eziphambili zeevalve zebhola eziphezulu
Iivalvu zebhola zokufikelela phezulu ziyilwe ngendawo yokungena ephakanyiswe phezulu ukuze kube lula ukufikelela kumacandelo angaphakathi. Olu phawu luvumela ukugcinwa ngokukhawuleza kunye nokulula, ukulungiswa kunye nokutshintshwa kweengxenye ngaphandle kokususa i-valve kumbhobho. Ukongezelela, idizayini yokungena ephezulu inciphisa umngcipheko wokuvuza kwaye iqinisekisa ukutywinwa okuqinileyo, okwenza kube yinto efanelekileyo yoxinzelelo oluphezulu kunye nokushisa okuphezulu.
Olunye uphawu oluhlukileyo lwe-valve yebhola yokufikelela phezulu kuyilo lwe-port epheleleyo, evumela ukuhamba okungathintekiyo kunye nokuhla koxinzelelo oluncinci. Olu phawu loyilo lubalulekile kwizicelo ezifuna ukuhamba kwamanzi okusebenzayo kunye nokulahleka kwamandla okuncinci.
Izinto eziluncedo kwiivalve zebhola ezifakwe phezulu
Enye yeenzuzo eziphambili zeevalvu zebhola zokufikelela phezulu kukwakhiwa kwazo okuqinileyo, okwenziwa ngokuqhelekileyo kwizinto ezikumgangatho ophezulu ezifana nensimbi engenasici, i-carbon steel, okanye i-alloy steel. Olu lwakhiwo luqinisekisa ubude be-valve kwaye lunciphisa isidingo sokugcinwa rhoqo kunye nokutshintshwa, naphantsi kweemeko zokusebenza ezinzima.
Ukongeza, iivalve zebhola ezibekwe phezulu zinomsebenzi obalaseleyo wokutywina ngenxa yoyilo lwebhola edadayo kunye nezixhobo zokutywina ezithembekileyo. Olu phawu lwenza ivalve ilungele ukusetyenziswa ngeentlobo ezahlukeneyo zolwelo, kubandakanywa imidiya eyonakalisayo kunye ne-abrasive, ngaphandle kokuchaphazela ukusebenza kwayo.
Ukusetyenziswa kweevalvu zebhola ezifakwe phezulu
Iivalve zebhola zokulayisha phezulu zisetyenziswa kumashishini ahlukeneyo, kubandakanywa ioli kunye negesi, i-petrochemicals, i-chemical processing, ukuveliswa kwamandla kunye nokunyanga kwamanzi. Ukuguquguquka kwayo kunye nokukwazi ukujongana noxinzelelo oluphezulu kunye namaqondo okushisa ayenza ifaneleke kwizicelo ezibalulekileyo ezifana nokuvalwa, ukuhlukaniswa kunye nokulawula ukuhamba kwamanzi.
Kwishishini leoli kunye negesi, iivalve zebhola ezixhonywe phezulu zisetyenziswa ngokuqhelekileyo kwiinkqubo zombhobho, i-wellheads kunye nezixhobo zokuvelisa. Ukukwazi kwabo ukumelana neemeko zokusebenza ezinzima kunye nokubonelela ngokuvalwa okuthembekileyo kubenza babe yinto ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokusebenza kakuhle kweoli kunye negesi.
Kwimizi-mveliso yeekhemikhali kunye ne-petrochemical, iivalve zebhola ezifakwe phezulu zisetyenziselwa ukuphatha i-corrosive and abrasive fluids ngenxa yolwakhiwo olunzima kunye neempawu ezibalaseleyo zokutywinwa. Ezi zivalo zidlala indima ebalulekileyo ekulawuleni ukuhamba kweekhemikhali kunye nokuqinisekisa ukunyaniseka kweenkqubo zenkqubo.
Ukuqukumbela, ivalve yebhola yokufikelela ephezulu licandelo eliguquguqukayo nelithembekileyo elibonelela ngeenzuzo ezininzi kwiinkqubo ezahlukeneyo zoshishino. Uyilo oluphezulu lokungena, ulwakhiwo olugqwethekileyo kunye neempawu ezibalaseleyo zokutywina zenza kube lukhetho lokuqala lwezicelo zolawulo olubalulekileyo lolwelo. Kungakhathaliseki ukuba kwi-oyile kunye negesi, ukuqhutyelwa kweekhemikhali okanye kumashishini okuvelisa amandla, ii-valve zebhola eziphezulu zihlala zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko, ukusebenza kakuhle kunye nokuthembeka kweenkqubo zoshishino.
