Ohlelweni lokuthutha nokulawula uketshezi oluyinkimbinkimbi noluthambile, izingxenye zamavalvu zifana neparele elikhanyayo, elikhanya ngokukhanya okubalulekile. Ziyizici eziyinhloko zokuqinisekisa ukusebenza okuphephile, okuzinzile nokusebenza kahle kwesistimu yonke, futhi indima yabo inkulu futhi ifinyelela kude, ihlanganisa izici eziningi ezibalulekile ezifana nokulawula ukugeleza, ukulawulwa kwengcindezi kanye nesiqondiso sesiqondiso sokugeleza.

Okokuqala, ukulawula ukugeleza kuwumsebenzi oyinhloko wezingxenye ze-valve. Ezinqubweni eziningi zokukhiqiza zezimboni, ukulawula ukugeleza okunembile kuyisihluthulelo sokuqinisekisa ikhwalithi nokukhiqiza komkhiqizo. Isibonelo, enqubweni yokuhlanganiswa kwamakhemikhali, izinto zokusetshenziswa zamakhemikhali ezihlukahlukene ezixutshwe ngesilinganiso esithile, ukugeleza kokuchezuka okuncane kungase kuholele ekuphenduleni okungalawuleki noma ikhwalithi yomkhiqizo ayifaneleki. Amavalvu okulawula adlala indima enhle kakhulu kule nqubo, kufana ne-bartender enekhono, ngokushintsha ukuvuleka kwayo, alungise kahle indawo enqamula uketshezi, ukuze akwazi ukulawula kahle ukugeleza. Kungakhathaliseki ukuthi ukunikezwa okunembile kokugeleza okuncane noma ukulawulwa okunengqondo kokulethwa koketshezi olukhulu, i-valve elawulayo iphezu komsebenzi wokuqinisekisa ukuthi ithonsi ngalinye loketshezi liyabandakanyeka ekukhiqizeni ngesikhathi esifanele nangenani elifanele.

Izingxenye ze-valve nazo ziwusizo ekulawuleni ingcindezi. Ezinhlelweni zamapayipi, ukuzinza komfutho we-fluid kuyisici esibalulekile ekugcineni ukuphepha nokusebenza ngendlela efanele kwesistimu. Amavalvu okuphepha angabagadi abathembekile bokuvikela ingcindezi. Lapho ingcindezi ohlelweni ikhuphuka ngaphezu komkhawulo wokuphepha ngenxa yezimo ezingalindelekile, amavalvu okuphepha asebenza njengezicishamlilo ezingamaqhawe, avule ngokushesha ukuze akhulule umfutho owedlulele, avimbele ipayipi ukuthi lingaqhume futhi liguge ngenxa yokucindezela okukhulu, futhi agweme umonakalo omkhulu okungenzeka okutholwe ezintweni zokusebenza nabasebenzi. Ngokuphambene, i-valve yokunciphisa ingcindezi iyisilawuli esimnene, izoba 'i-tantrums' yomfutho ophezulu wengcindezi, inciphise inqubo elandelayo noma imishini ingamelana nobubanzi obufanele bokucindezela, ukuze kuqinisekiswe ukuthi isistimu ezidingo zengcindezi ehlukene ye- ukuzinza kokuhlangana.

Ukulawula ukugeleza nakho kuyindawo lapho izingxenye ze-valve zibonisa ukuthandeka kwazo okuyingqayizivele. Kunethiwekhi yamapayipi eyinkimbinkimbi, uketshezi kufanele lulandele indlela enqunywe kusengaphambili yokugeleza. I-valve yokuhlola ingumnakekeli wendlela eyodwa wale ndlela, evumela uketshezi ukuba ludlule ohlangothini olulodwa kuphela, njengophawu lwendlela eyodwa emgwaqeni wethrafikhi, luvimbele ngokuphumelelayo uketshezi ukuthi lungagelezi luye emuva futhi lugweme ukulimala kwemishini noma amasistimu akhuphukayo. . Ezinhlelweni zokuhlinzeka ngamanzi kanye ne-drainage, ama-valve okuhlola avimbela ukugeleza kwendle, ukuqinisekisa izinsiza zamanzi ahlanzekile kanye nenhlanzeko yesistimu. Nakuba ama-valve ezindlela ezintathu, ama-valve anendlela emine namanye ama-valve ezindlela eziningi afana nezibani zesignali nezinduku ezimpambanweni zethrafikhi eziyinkimbinkimbi, angashintsha ngendlela eguquguqukayo indlela okugeleza ngayo uketshezi ngokwezidingo zesistimu futhi aqondise ukwabiwa okuhlelekile koketshezi endaweni ngayinye. igatsha lamapayipi, ukuze lonke uhlelo lufane nokusebenza kahle kakhulu kwenethiwekhi yezokuthutha.

Ngaphezu kwalokho, kukhona ama-valve ebhola, ama-butterfly valves, ama-valve embulunga nezinye izinhlobo ezahlukene zezingxenye ze-valve, ngayinye edlala indima engenakuthathelwa indawo ezimweni ezihlukene zohlelo lokusebenza ngesakhiwo sayo esiyingqayizivele nezici zokusebenza. Kungakhathaliseki ukuthi ukudluliswa kukawoyela negesi, ukuhlinzekwa kwamanzi emadolobheni kanye ne-drainage, noma imithi, ukucubungula ukudla nezinye izimboni, izingxenye zamavalvu seziyingxenye ebalulekile yesistimu yoketshezi ngomsebenzi wawo omuhle kakhulu, ziqapha buthule uhambo lweconsi ngalinye loketshezi.
