Kwinkqubo yokuthutha nokulawula ulwelo oluntsonkothileyo noluthambileyo, iinxalenye zevalvu zifana neperile eqaqambileyo, ekhanyayo ngokukhanya okubalulekileyo. Zizona zinto zibalulekileyo zokuqinisekisa ukusebenza okukhuselekileyo, okuzinzile kunye nokusebenza kakuhle kwenkqubo yonke, kwaye indima yabo ibanzi kwaye ifikeleleke kakhulu, iquka inani lemiba ephambili efana nokulawula ukuhamba, ukulawulwa koxinzelelo kunye nesikhokelo sokuhamba.

Okokuqala, ulawulo lokuhamba ngumsebenzi ophambili wezakhi zevalvu. Kwiinkqubo ezininzi zemveliso yoshishino, ulawulo oluchanekileyo lokuhamba lungundoqo ekuqinisekiseni umgangatho wemveliso kunye nemveliso. Umzekelo, kwinkqubo yokwenziwa kweekhemikhali, izinto ezahlukeneyo zemichiza ekrwada exutywe kumlinganiselo othile, ukuhamba kokutenxa okuncinci kunokukhokelela ekuphenduleni okungalawulwayo okanye umgangatho wemveliso awufanelekanga. Izivalo zokulawula zidlala indima ebalaseleyo kule nkqubo, ifana ne-bartender enobuchule, ngokutshintsha ukuvulwa kwayo, ukulungelelanisa ngokuchanekileyo indawo enqamlezayo yolwelo, ukuze kufezekiswe ulawulo oluhle lokuhamba. Nokuba lunikezelo oluchanekileyo lokuhamba okuncinci okanye ulawulo olunengqiqo lonikezelo lolwelo olukhulu, ivalve elawulayo ixhomekeke kumsebenzi wokuqinisekisa ukuba ithontsi ngalinye lolwelo libandakanyeka kwimveliso ngexesha elifanelekileyo kunye nesixa esifanelekileyo.

Amacandelo e-valve nawo aluncedo ekulawuleni uxinzelelo. Kwiinkqubo zemibhobho, ukuzinziswa koxinzelelo lwe-fluid yinto ebalulekileyo ekugcineni ukhuseleko kunye nokusebenza ngokufanelekileyo kwenkqubo. Iivalvu zokhuseleko ngabagadi abathembekileyo bokhuseleko loxinzelelo. Xa uxinzelelo kwinkqubo lunyuka ngaphezu komda wokhuseleko ngenxa yeemeko ezingalindelekanga, iivalvu zokhuseleko zisebenza njengabacimi-mlilo abakhaliphileyo, zivula ngokukhawuleza ukukhulula uxinzelelo olugqithisileyo, zithintela ukugqabhuka kunye nokonakala kombhobho ngenxa yoxinzelelo olugqithisileyo, kunye nokuphepha umonakalo omkhulu onokuthi zifakwe kwizixhobo nabasebenzi. Ngokwahlukileyo, ivalve yokunciphisa uxinzelelo ngumlawuli othambileyo, iya kuba yi-high-pressure fluid 'tantrums' ithotywe, iyancipha ukuya kwinkqubo elandelayo okanye izixhobo ezinokumelana noluhlu olufanelekileyo loxinzelelo, ukuqinisekisa ukuba inkqubo kwiimfuno ezahlukeneyo zoxinzelelo uzinzo lokuhlangana.

Ulawulo lokuhamba lukwayindawo apho amacandelo evalve abonisa umtsalane wawo okhethekileyo. Kuthungelwano lwemibhobho entsonkothileyo, ulwelo kufuneka lulandele indlela yokuhamba emiselwe kwangaphambili. I-valve yokutshekisha ngumgcini wendlela enye yale ndlela, evumela ulwelo ukuba ludlule kwicala elinye kuphela, njengophawu lwendlela enye kwindlela yezothutho, ukuthintela ngokufanelekileyo ulwelo ukuba luhambe ngasemva kwaye lugweme umonakalo kwisixhobo esinyukayo okanye iinkqubo. . Kwiinkqubo zokubonelela ngamanzi kunye nokuhanjiswa kwamanzi, ii-valve zokuhlola zithintela ukubuyisela umva kwamanzi amdaka, ziqinisekisa ubutyebi bamanzi acocekileyo kunye nococeko lwenkqubo. Ngelixa iivalve ezinendlela-ntathu, iivalve ezinendlela emine kunye nezinye iindlela ezininzi zifana nezibane zomqondiso kunye neebatons kwiindlela ezintsonkothileyo zendlela, zinokutshintsha ngokuguquguqukayo indlela yokuhamba kwamanzi ngokweemfuno zenkqubo kwaye zikhokele ukusasazwa ngocwangco kolwelo kwindawo nganye. isebe lombhobho, ukuze yonke inkqubo ifane nokusebenza kakuhle kakhulu kothungelwano lolungiselelo.

Ukongeza, kukho iivalve zebhola, iivalve zebhabhathane, iivalve zeglowubhu kunye nezinye iintlobo ezahlukeneyo zamacandelo evalve, nganye kuzo idlala indima engenakuthathelwa indawo kwiimeko ezahlukeneyo zesicelo kunye nesakhiwo sayo esisodwa kunye neempawu zokusebenza. Nokuba kukuhanjiswa kwe-oyile kunye negesi, ukuhanjiswa kwamanzi ezidolophini kunye ne-drainage, okanye amayeza, ukusetyenzwa kokutya kunye namanye amashishini, iinxalenye zevalvu ziye zaba yinxalenye eyimfuneko yenkqubo yolwelo kunye nomsebenzi wayo obalaseleyo, ngokuthula ukugada uhambo lwethontsi ngalinye lolwelo.
