Iivalvu zebhabhathane: Izisombululo eziguquguqukayo zolawulo lokuqukuqela

Iivalve zebhabhathane zizinto ezibalulekileyo kwiinkqubo ezahlukeneyo zemizi-mveliso, ezibonelela ngezisombululo eziguquguqukayo nezithembekileyo zolawulo lokuhamba. Zithiywe ngokufana kwazo namaphiko ebhabhathane, ezi zivalo zenzelwe ukulawula ukuhamba kolwelo okanye irhasi kusetyenziswa idiski ejikelezayo kwi spindle. Ngoyilo lwazo olulula kodwa olusebenzayo, iivalve zebhabhathane ziye zaba lukhetho oludumileyo kumashishini afana neoyile negesi, unyango lwamanzi, ukutya nesiselo, kunye neenkqubo zeHVAC.

Enye yeenzuzo eziphambili zeevalve zebhabhathane kukuguquguquka kwazo. Ezi valves ziza kwiintlobo ezahlukeneyo zobukhulu, ukusuka kwii-intshi ezimbalwa ukuya kwiinyawo ezininzi ububanzi, ukuze zilungele iintlobo ezahlukeneyo zokuhamba kunye nokusetyenziswa. Nokuba ilawula ukuhamba kwamanzi kumbhobho okanye ukulawula uxinzelelo lwerhasi kwiplanti yenkqubo, iivalvu zebhabhathane zinokulungiswa ukuhlangabezana neemfuno ezithile. Isici sabo sokuguquguquka esilungelelanisiweyo sivumela ulawulo lokuhamba oluchanekileyo, lubenza lube lulungele usetyenziso olufuna umgaqo ochanekileyo wokuhamba.

Iivalve zebhabhathane nazo zaziwa ngokusebenza kwazo ngokulula. I-disc yevalve ifakwe kwi-spindle. Xa i-valve ivalwe ngokupheleleyo, i-disc ye-valve i-perpendicular ukuya kwicala lokuhamba; xa ivalve ivuleke ngokupheleleyo, idiskhi yevalve i-perpendicular ukuya kwicala lokuhamba. Ngekota elula yokujika kwe-spindle, i-disc ijikeleza kuyo nayiphi na indawo efunwayo, ivumela ukuba kube lula, ukulawula ukuhamba ngokufanelekileyo. Olu yilo lwahlukileyo lunciphisa ilahleko yokungqubana kunye nokuhla koxinzelelo, ngaloo ndlela kwandisa ukusebenza kwenkqubo.

Ukongeza, iivalve zebhabhathane zinomsebenzi obalaseleyo wokutywina. I-disc idla ngokwenziwa ngentsimbi okanye i-elastic material kwaye yenzelwe ukwenza itywina eliqinileyo xa licinezelwe kwisitulo sevalve. Oku kuqinisekisa ukuvuza kuncitshisiwe kwaye umngcipheko wongcoliseko okanye ukulahleka kolwelo kuncitshisiwe. Indlela yokutywina yongezwa ngakumbi kusetyenziso lwemathiriyeli ye-elastomeric efana nerabha okanye i-PTFE, enika ukuxhathisa okugqwesileyo ekudlekeni nasekunxibeni. Oku kwenza iivalvu zebhabhathane zilungele ukuphatha iintlobo ngeentlobo zolwelo, kuqukwa neekhemikhali ezonakalisayo kunye nodaka olurhabaxa.

Olunye uncedo olubalulekileyo lweevalvu zebhabhathane kukuyilwa kwazo okuhlangeneyo, nokukhaphukhaphu. Iivalve zebhabhathane zifuna indawo encinci yokufakela xa kuthelekiswa nezinye iindidi zeevalvu, zizenza zilungele usetyenziso apho indawo incinyiweyo. Ulwakhiwo olukhaphukhaphu lukwalula uthutho kunye nenkqubo yokufakela, ukunciphisa iindleko ezinxulumene nexesha. Ukongeza, iivalve zebhabhathane kulula ukuzigcina, zineenxalenye ezimbalwa kunye namanqaku ambalwa okusilela, ukunciphisa ixesha lokuphumla kunye nokwandisa ukusebenza kakuhle.

Nangona iivalve zebhabhathane zibonelela ngeengenelo ezininzi, izinto ezithile kufuneka ziqwalaselwe xa ukhetha ivalve echanekileyo yosetyenziso oluthile. Izinto ezifana nohlobo lolwelo olulawulwayo, uxinzelelo lokusebenza kunye nobushushu, kunye namazinga okuhamba afunekayo kufuneka athathelwe ingqalelo. Ukubonisana nengcaphephe yevalvu kwaye kuthathelwe ingqalelo umenzi othembekileyo kubalulekile ekuqinisekiseni ukhetho kunye nofakelo lwevalvu yebhabhathane.

Isishwankathelo, iivalve ze-butterfly ziyisisombululo esisebenzayo nesithembekileyo sokulawula ukuhamba kwiintlobo ezahlukeneyo zezicelo zoshishino. Ngokuguquguquka kwazo, ukusebenza ngokulula, ukutywinwa okugqwesileyo kunye noyilo oludibeneyo, iivalve zebhabhathane zibonelela ngesisombululo esisebenzayo kunye neendleko zokulawula ukuhamba kwamanzi. Xa ukhetha i-valve butterfly, iimfuno ezithile zesicelo kufuneka ziqwalaselwe ngokucophelela ukuze kuqinisekiswe ukusebenza kakuhle kunye nokuthembeka kwexesha elide. Ngokukhetha i-valve ye-butterfly efanelekileyo, amashishini anokuqinisekisa ukusebenza kakuhle kunye nokusebenza kakuhle ngelixa befezekisa iinjongo zabo zokulawula ukuhamba okufunekayo.
