Iivalve zeplagi zizinto ezibalulekileyo ezisetyenziswa kuluhlu olubanzi lwamashishini kunye nokusetyenziswa. Ezi zivalo zenzelwe ukulawula ukuhamba kwamanzi ngokusebenzisa iinkqubo zemibhobho, ezivumela ukulawulwa lula kunye nokusebenza kakuhle. Ngoyilo lwazo olulula kodwa olusebenzayo, iivalve zeplagi lukhetho oludumileyo phakathi kweengcali ezininzi.
Umsebenzi ophambili wevalve yeplagi kukuqalisa, ukumisa okanye ukucinezela ukuhamba kwezinto. Ziquka iplagi ye-cylindrical okanye i-conical enembobo (ebizwa ngokuba yi-port) phakathi. Ngokuguqula iqhude kumzimba we-valve, i-port inokulungelelaniswa okanye ivalwe kumbhobho, ngaloo ndlela ilawula ukuhamba. Lo matshini unika ivalve yeplagi igama layo elilodwa.
Enye yeenzuzo eziphambili zeeplagi zeplagi kukukwazi ukubonelela ngokulawula okupheleleyo kokuhamba. Xa iplagi ivuleke ngokupheleleyo, izinga lokuqukuqela liyenyuka, livumela ulwelo ukuba luhambe ngokufanelekileyo nangokungathintelekiyo. Ngokuchasene noko, ukuvala isithinteli kuya kumisa ukuhamba ngokupheleleyo. Eli nqanaba lolawulo libalulekile kumashishini afuna ukulawulwa kokuhamba okuchanekileyo, okufana neoli kunye negesi, unyango lwamanzi, kunye nezityalo zemichiza.
Iivalve zeplagi nazo ziyaziwa ngokuhlala kwazo kunye nokuthembeka. Zakhiwe kwizinto ezomeleleyo ezifana nensimbi engenasici, i-carbon steel okanye i-cast iron cast, ukuqinisekisa ukuba banokumelana neemeko zokusebenza ezinzima. Oku kubenza balungele ukusetyenziswa kwiinkqubo zoxinzelelo oluphezulu okanye indawo equlethe izinto ezidliwayo. Ngokulungiswa okufanelekileyo, iiplagi zeeplagi zinokuba nobomi obude benkonzo, ukunciphisa isidingo sokutshintshwa rhoqo kunye nokunciphisa ixesha lokuphumla.
Ukongeza, iivalvu zeplagi zinokunganyangeki kwamanzi xa zivuleke ngokupheleleyo. Olu phawu lufanelekile xa lujongene ne-viscous okanye i-media abrasive njengoko kunciphisa ithuba lokuvala okanye ukulimaza i-valve. Umzila wokuhamba olungelelanisiweyo owenziwe yiplagi evulekileyo ivumela ukuhamba kwamanzi agudileyo, ukuthintela ukuhla koxinzelelo olungadingekile kunye nokuphucula ukusebenza kwenkqubo.
Enye inzuzo yeeplagi zeplagi kukuguquguquka kwazo. Zingasetyenziswa kwiinkqubo ezahlukeneyo ezibandakanya ukutshintsha kunye neenkonzo ze-throttling. Ezi zivalo zilungele ukuphatha iintlobo ezahlukeneyo zolwelo olufana nolwelo, iigesi, i-slurries kunye nomgubo. Ukongeza, iivalve zeplagi zifanelekile kuluhlu olubanzi lobushushu, nto leyo ezenza zilungele iinkqubo ezishushu kakhulu nezibandayo.
Nangona i-valve yeplagi ineenzuzo ezininzi, nayo inemida. Enye yezinto ezingeloncedo kubo kukuvuza xa ivaliwe. Ngenxa yezizathu zoyilo, kuhlala kukho umsantsa omncinci phakathi kweplagi kunye nesitulo sevalvu, enokubangela inqanaba elithile lokuvuza. Nangona kunjalo, ukuhambela phambili kwetekhnoloji kuye kwanceda ekunciphiseni le ngxaki, kwaye iivalvu zeplagi zanamhlanje zihlala zibandakanya izinto ezinje ngokutywinwa kabini okanye iingubo ezikhethekileyo zokunciphisa ukuvuza.
Ukuqukumbela, iivalve zeplagi ziye zaba yinxalenye yamashishini amaninzi ngenxa yokusebenza kakuhle, ukuqina kunye nokuguquguquka. Ukukwazi kwabo ukulawula ngokuchanekileyo ukuhamba kwamanzi kubenza babe lolona khetho lokuqala kwiingcali ezifuna ukulawulwa okuthembekileyo, okusebenzayo. Njengoko uyilo kunye nobuchwepheshe buqhubela phambili, iivalvu zeplagi ziyaqhubeka nokuvela, zibonelela ngokusebenza okuphuculweyo kunye nokuhlangabezana neemfuno zokutshintsha kweshishini.
