Kumashishini ahlukeneyo afana neoli kunye negesi, i-petrochemical, kunye nokuveliswa kwamandla, ukuqinisekisa ukhuseleko lwezibonelelo kunye nabasebenzi kubaluleke kakhulu. Enye inkalo ebalulekileyo kwiinkqubo zokukhusela umlilo sisivalufa se-alam ye-flange. Le valve idlala indima ephambili ekuthinteleni ukusasazeka komlilo kunye nokunciphisa umonakalo kwipropati kunye nezixhobo.
Iivalvu ze-alam ze-Flangezenzelwe ngokukodwa ukulawula ukuhamba kwamanzi kwiinkqubo zokukhusela umlilo. Ezi nkqubo ziqhele ukusetyenziswa kwiindawo ezinobungozi obukhulu apho umngcipheko womlilo uphakanyisiwe. Iivalve zixhotyiswe ngegumbi le-diaphragm elixinzelelwe ngomoya okanye i-nitrogen. Xa umlilo ubhaqwe, inkqubo ikhupha uxinzelelo kwi-diaphragm chamber, ivumela ivalve ukuba ivuleke kwaye amanzi aphume kwiintloko zokufafaza.
Enye yeenzuzo eziphambili ze-alam ye-alam ye-flange kukukwazi ukubonelela ngokukhawuleza nangempendulo esebenzayo emlilweni. Ngokuhambisa ngokukhawuleza umthamo omkhulu wamanzi kwindawo echaphazelekayo, ezi zivalo zinokunceda ukuquka nokucima umlilo ngaphambi kokuba unyuke. Ukongezelela, ii-alamu ezivakalayo nezibonakalayo ezinxulumene nezi zivalo zilumkisa abasebenzi malunga nobukho bomlilo, okuvumela ukukhutshwa ngokukhawuleza kunye nokuphendula.
Ukongeza kwizakhono zabo zokucima umlilo, iivalvu ze-alarm ze-flange zibonelela ngokhuseleko kwii-alamu zobuxoki kunye nokukhutshwa ngengozi. Iivalvu zixhotyiswe ngesixhobo sokuvala esithintela ukuba zingavuleki ngaphandle kokuba isixokelelwano senziwe sisixhobo sokubona umlilo.
Xa kufikwa kufakelo kunye nokugcinwa kwe-alam ye-alam ye-flange, kubalulekile ukusebenza neengcali eziqeqeshiweyo ezinamava ngezi nkqubo. Ufakelo olululo kunye nokuhlolwa rhoqo kubalulekile ekuqinisekiseni ukuba iivalvu zisebenza ngokufanelekileyo xa zifuneka.
Ukuqukumbela, iivalvu ze-alarm ze-flange ziyinxalenye ebalulekileyo yeenkqubo zokukhusela umlilo kwiindawo ezinomngcipheko ophezulu. Ukukwazi kwabo ukuhambisa amanzi ngokukhawuleza kunye nokubonelela ngokukhangela umlilo okuthembekileyo kubenza babe yimpahla ebalulekileyo yokukhusela izixhobo kunye nabasebenzi. Ngokuqonda ukubaluleka kwezi zivalo kunye nokutyalomali ekufakeni nasekugcinweni kwazo ngokufanelekileyo, amashishini anokuphucula imilinganiselo yokhuseleko lomlilo ngokubanzi.
