Ukuqonda imisebenzi yeevalvu zesango kwizixhobo zokulawula kakuhle
Kwinkalo yezixhobo zokulawula umthombo,iivalve zesangoidlala indima ebalulekileyo ekugcineni ukhuseleko lokusebenza nokusebenza kakuhle. Kodwa zikwenza njani kanye eziiivalveumsebenzi kwaye kutheni zibalulekile kwishishini leoli negesi? Kule bhlog, siza kujonga ngakumbi ukusebenza kwangaphakathi kweevalvu zesango kwaye sixoxe ngokubaluleka kwazo kwinkqubo yolawulo lomthombo.
Ivalve yesango sisivalo esisebenzisa isango lokutyibilika ukulawula ukuhamba kwamanzi. Kwizixhobo zokulawula kakuhle, iivalve zesango zilawula ukuhamba kwamanzi okugaya, i-samente kunye nezinye izinto ngexesha lezigaba ezahlukeneyo zokugaya kunye nenkqubo yokuvelisa. Umsebenzi wabo oyintloko kukubonelela ngendlela ethembekileyo nekhuselekileyo yokulawula ukuhamba kwamanzi, ngaloo ndlela iqinisekisa ukhuseleko kunye nokunyaniseka kwequla.
Enye yezona zinto zibalulekileyo kwiivalve zesango kukukwazi ukubonelela ngesitywina esiqinileyo xa ivaliwe, ukukhusela ngokufanelekileyo ukuhamba kwamanzi. Oku kubalulekile kwimisebenzi yolawulo lomthombo njengoko ihlukanisa iinxalenye ezithile zomthombo, ukuthintela ukukhutshwa okungalawulekiyo kolwelo okanye ukwakhiwa koxinzelelo. Ukongezelela, iivalve zesango zenzelwe ukujamelana noxinzelelo oluphezulu kunye namaqondo okushisa aphezulu, okwenza kube yinto efanelekileyo yokusetyenziswa kwiindawo ezinzima ezidibana nokusebenza kweoli kunye negesi.
Ke, isebenza njani ivalve yesango? Imigaqo esisiseko yokusebenza kwevalvu yesango ilula. Xa ivalve ikwindawo evulekileyo, isango liyarhoxa, livumela ulwelo ukuba luhambe ngokukhululekileyo kwivalve. Endaweni yoko, xa ivalve ivala, isango lityhalwa lijonge ezantsi ukwenza itywina eliqinileyo, lithintele ulwelo ukuba ludlule. Inkqubo ilawulwa yintshukumo ye-valve stem kwaye ngokuqhelekileyo iqhutywe ngesandla okanye isebenzisa i-hydraulic okanye i-pneumatic system.
Kwizixhobo zokulawula kakuhle, iivalve zesango zihlala zisetyenziswa ngokubambisana nezinyeiintlobo zeevalvukunye nezixhobo zokhuseleko zokuqinisekisa ulawulo olupheleleyo lomthombo. Umzekelo, zinokufakwa ecaleniiivalve zebhola, i-throttles kunye namanye amacandelo abalulekileyo ukubonelela ngeendlela ezininzi zokukhusela kunye nokulawula. Le ndlela inamaleko amaninzi inceda ukunciphisa umngcipheko kwaye iqinisekise ukusebenza kakuhle ngokukhuselekileyo nangokufanelekileyo.
Isishwankathelo, iivalve zesango ziyinxalenye ebalulekileyo yezixhobo zokulawula umthombo kwaye zidlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi kunye nokugcina ingqibelelo kakuhle. Ukukwazi kwabo ukubonelela ngesitywina esikhuselekileyo, ukumelana noxinzelelo oluphezulu kunye nokusebenza ngokubambisana nezinye iivalve kubenza babaluleke kakhulu kwishishini leoli kunye negesi. Ngokuqonda umsebenzi weevalve zesango kunye nokubaluleka kwazo kwimisebenzi yokulawula kakuhle, iingcali zoshishino zinokusebenza ukuphucula ukhuseleko kunye nokuthembeka kwemisebenzi yabo.
