Irabha ehleli iivalvu zokujonga ipleyiti ephindwe kabini ngamacandelo abalulekileyo kuluhlu olubanzi lwezicelo zamashishini.Zisetyenziselwa ukulawula ukuhamba kwamanzi kwimibhobho kunye nezinye iinkqubo, ukuqinisekisa ukuba ulwelo luhamba ngendlela efunwayo ngaphandle kokubuyela umva okanye ukuvuza.

Ke, yintoni kanye kanye isitulo serabha sokujonga ipleyiti ephindwe kabini?Ukubeka nje, i-valve yokutshekisha enediski ezimbini okanye iipleyiti ezigcinwe kwindawo ephethwe yi-spring-loaded mechanism.Ezi pleyiti zenzelwe ukuvala ngokuqinileyo ngezitywina zerabha, ukuthintela ukuhamba kwamanzi kwelinye icala.Xa ulwelo lubuyiselwa umva, iipleyiti zityhalwa ngokwahlukeneyo luxinzelelo lwencindi kwaye zivumela ulwelo ukuba luhambe luye kwicala elifunekayo.

Enye yeenzuzo eziphambili zerabha ehleli iivalvu zokujonga ipleyiti ephindwe kabini kuyilo lwazo olubambeneyo.Ngokuqhelekileyo zincinci kwaye zikhaphukhaphu kunezinye iintlobo zeevalvu zokutshekisha, zizenza zilungele usetyenziso apho indawo incinyiweyo.Kwakhona kulula ukuyifaka kunye nokugcina, kunceda ukunciphisa ixesha lokunciphisa kunye nokwandisa ukusebenza kakuhle.

Irabha ehleli iivalvu zokujonga ipleyiti ephindwe kabini zisetyenziswa kuluhlu olubanzi lwezicelo zamashishini ezibandakanya ukusetyenzwa kweekhemikhali, ukuveliswa kweoyile negesi, kunye nokucocwa kwamanzi amdaka.Zilungele usetyenziso apho kukho umngcipheko omkhulu wokubuyela umva, njengeempompo, iicompressors kunye nemibhobho ethwele ulwelo oludlekayo okanye olurhabaxa.

Enye yezona zinto zibalulekileyo zokuqwalaselwa xa ukhetha isihlalo serabha sokujonga i-valve yokujonga ipleyiti ephindwe kabini zizinto zokwakha.Kubalulekile ukukhetha i-valve ehambelana nolwelo oluhanjiswa kwisistim kunye nobushushu kunye neemeko zoxinzelelo.I-rubber ehleliyo i-valve yokukhangela i-rubber ifumaneka kwizinto ezahlukeneyo ezibandakanya insimbi engenasici, i-carbon steel kunye ne-ductile iron.

Enye into ekufuneka uyiqwalasele xa ukhetha irabha ehleli ivalve yokujonga ipleyiti ephindwe kabini luhlobo lwetywina lerabha elisetyenzisiweyo.Iindidi ezahlukeneyo zerabha zineepropati ezahlukeneyo, ezifana nokuxhathisa i-corrosion, ukumelana ne-abrasion kunye nokumelana nokushisa okuphezulu.Kubalulekile ukukhetha uphawu lwerubha oluchanekileyo kwisicelo esithile.

Isishwankathelo, irabha ehleli iivalvu zokujonga ipleyiti ephindwe kabini ngamacandelo ayimfuneko kuluhlu olubanzi lwezicelo zoshishino.Zenzelwe ukulawula ukuhamba kwamanzi kwimibhobho kunye neenkqubo, ukuqinisekisa ukuba ulwelo luhamba ngendlela efunwayo ngaphandle kokuhamba ngasemva okanye ukuvuza.Xa ukhetha i-valve yokujonga i-rubber ehleliyo, kubalulekile ukuqwalasela izinto zokwakha kunye nohlobo lwesitywina serubha esisetyenziselwa ukuqinisekisa ukuba i-valve ifanelekile kwisicelo esithile.
