Iivalve zeplagi ziyinxalenye ebalulekileyo yamashishini ahlukeneyo kwaye anoluhlu olubanzi lwezicelo kunye neenzuzo. Ukusuka ekulawuleni ukuhamba ukuya ekuboneleleni ukuvala okuthembekileyo, iivalve zeplagi zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kweenkqubo ezahlukeneyo. Kwesi sikhokelo sibanzi, siza kujonga ngakumbi ukuguquguquka kweevalvu zeplagi, sijonge imisebenzi yazo, iindidi, kunye nendima ebalulekileyo eziyidlalayo kumashishini ahlukeneyo.
Imisebenzi kunye nezicelo
Iivalve zeplagi zenzelwe ukulawula ukuhamba kolwelo okanye igesi kwimibhobho. Uyilo lwayo olulula kodwa olusebenzayo lubandakanya iplagi yecylindrical okanye iconical ejikeleza ngaphakathi kumzimba wevalvu ukulawula ukuhamba. Lo matshini ulawula ngokuchanekileyo ukuhamba kwaye unikezela ngokuvalwa okuthembekileyo xa kuyimfuneko.
Enye yeenzuzo eziphambili zeevalve zeplagi kukuguquguquka kwazo ekuphatheni iintlobo ezahlukeneyo zeendaba, kubandakanywa iikhemikhali ezitshabalalisayo, i-slurries e-abrasive kunye ne-high-pressure gases. Oku kubenza bafaneleke kumashishini afana ne-oyile negesi, ukusetyenzwa kweekhemikhali, ukucocwa kwamanzi kunye nokuvelisa umbane.
Iindidi zeeplagi zeplagi
Kukho iintlobo ezininzi zeeplagi zeplagi, nganye yenzelwe ukuhlangabezana neemfuno ezithile kunye neemeko zokusebenza. Ezi zibandakanya iivalvu zeplagi ezithathiweyo, iivalve zeplagi ezingaxutywanga kunye ne-eccentric plug valves. Iivalve zeplagi ezithanjiswayo zixhotyiswe nge-lubricant injection system yokunciphisa ukukhuhlana kunye nokuguga, ngelixa iivalve zeplagi ezingaxutywanga ziyilelwe usetyenziso apho ukungcoliseka kwe-lubricant kuyinkxalabo. Iivalvu zeplagi ze-Eccentric zibandakanya uyilo lweplagi ye-offset ebonelela ngesitywina esiqinileyo kunye nokunciphisa ukunxiba ngexesha lokusebenza.
Ukuguquguquka kweevalve zeplagi kuphuculwe ngakumbi ngokusetyenziswa kwezixhobo ezahlukeneyo zeplagi ezifana neentsimbi, iiplastiki kunye ne-elastomers, ezivumela ukuhambelana neentlobo zeendaba kunye neemeko zokusebenza.
Dlala indima ephambili kumashishini ahlukeneyo
Kwishishini leoli kunye negesi, iivalvu zeplagi zisetyenziselwa ukulawula ukuhamba kwe-oyile ekrwada, igesi yendalo kunye neemveliso ezisulungekileyo. Ukukwazi kwabo ukujongana noxinzelelo oluphezulu kunye neemeko zokushisa eziphezulu zibenza zibe zilungele ukunyusa, umlambo kunye nezicelo ezisezantsi.
Kwizityalo zokusetyenzwa kweekhemikhali, iivalve zeplagi zisetyenziselwa ukuphatha imichiza eyonakalisayo kunye ne-slurries e-abrasive. Ulwakhiwo lwazo olumagingxigingxi kunye nezinto ezikwaziyo ukumelana nomhlwa zizenza zifaneleke ngokufanelekileyo iimeko ezimaxongo ezifumaneka kwiindawo zokulungisa imichiza.
Iindawo zokucocwa kwamanzi zisebenzisa ii-stopcocks ukulawula ukuhamba kwamanzi, imichiza kunye namanzi amdaka. Izakhono zayo ezithembekileyo zokuvala kunye nokumelana nokubola kwenza kube yinto ebalulekileyo yeenkqubo zokunyanga amanzi.
Ekuveliseni umbane, iivalvu zeplagi zisetyenziswa kwi-steam kunye neenkqubo zamanzi ukulawula ngokuchanekileyo ukuhamba kunye nokuvalwa kwamanzi okuphakela kwibhoyila, amanzi okupholisa kunye neenkqubo zokuhambisa umphunga.
ukuququmbela
Ukuguquguquka kweeplagi zeplagi kubenza babe yimpahla ebalulekileyo kumashishini ahlukeneyo, ukubonelela ngolawulo oluthembekileyo lokuhamba kunye nemisebenzi yokuvala imidiya eyahlukeneyo kunye neemeko zokusebenza. Enokuba uphatha imichiza eyonakalisayo kwimizi-mveliso yokwenziwa kweekhemikhali okanye ulawula ukuhamba kwerhasi yendalo kwizibonelelo ze-oyile nerhasi, izivalo zeeplagi zidlala indima ebalulekileyo ekuqinisekiseni ukuba iinkqubo zemizi-mveliso zisebenza ngokufanelekileyo nangokukhuselekileyo. Ngezicelo zabo ezahlukeneyo kunye nokwakhiwa okunzima, iivalve zeplagi zihlala ziyinxalenye ebalulekileyo yoshishino lokulawula ulwelo.
