Izivalo zebhabhathane zidlala indima ebalulekileyo xa kufikwa kulawulo lokuhamba kolwelo kwiinkqubo zemibhobho. Kwizicelo zamashishini,Iivalvu zebhabhathane zePVClukhetho oludumileyo ngenxa yokuqina kunye nokusebenza kakuhle. Kweli nqaku, siza kujonga nzulu kwimisebenzi yeevalvu zebhabhathane, ngakumbi ezo zenziwe ngePVC, kwaye siphonononge ukuba kutheni zibalulekile kumashishini ahlukeneyo.

Umsebenzi wevalve yebhabhathaneilula kodwa ibaluleke kakhulu. Ngokusisiseko, ilawula ukuhamba kwamanzi ngokusebenzisa idiski ebizwa ngokuba "ibhabhathane" elisembindini wombhobho. Ngokungafaniyo neevalvu zebhola, ezisebenzisa ibhola ukulawula ukuhamba, idiski yevalve yebhabhathane ixhonywe kwishafti ejikelezayo. Xa i-valve ikwindawo evaliweyo, i-disc i-perpendicular to flow of fluid, ithintela ngokufanelekileyo i-fluid. Xa ivuliwe, i-disc ijikeleza ngokuhambelana necala lokuhamba kwamanzi, ivumela ulwelo ukuba ludlule.

Izinto zePVC zongeza omnye umaleko wokusebenza kunye nokuthembeka kwiivalve zebhabhathane. I-PVC, okanye i-polyvinyl chloride, i-thermoplastic enokumelana nekhemikhali egqwesileyo kwaye ifanelekile kwiinkqubo ezahlukeneyo. Ngaphandle kokukwazi ukumelana neekhemikhali ezidliwayo, iPVC ikhaphukhaphu, kulula ukuyifaka, kwaye iyabiza, iyenza ibe yeyona nto ifanelekileyo kwizivalo zebhabhathane.

Iivalvu zebhabhathane zePVC zithandwa kakhulukwiindawo zoshishino apho ukuqukuqela kolwelo oludlekayo kuxhaphakile. Ikhono layo lokumelana neekhemikhali ezinobunzima kunye nokushisa okugqithisileyo kwenza kube yinto ebalulekileyo kwizityalo zokucutshungulwa kweekhemikhali, amaziko okucoca amanzi kunye neenkqubo zokulawula amanzi amdaka. Ukuqina kunye nokuqina kweevalve ze-butterfly ze-PVC ziqinisekisa ukuba zinokubonelela ngenkonzo yexesha elide, ethembekileyo kwiindawo ezifunayo.

Ukongeza, iivalvu zebhabhathane zePVC zikwasetyenziswa ngokubanzi ukuthutha amanzi kunye nolunye ulwelo olungadlekiyo. Umphezulu wayo wangaphakathi ogudileyo unciphisa ukuhla koxinzelelo kunye nesiphithiphithi, oko kuyenza ibe lukhetho oluwonga amandla kulawulo lolwelo. Oku kwenza iivalve zebhabhathane ze-PVC zibe lukhetho oludumileyo kwiinkqubo ze-HVAC, iinkqubo zokunkcenkceshela kunye nothungelwano lokuhambisa amanzi.

Enye inkalo ebalulekileyo yomsebenzi weevalve zebhabhathane, kubandakanywa nezo zenziwe ngePVC, kukukwazi ukulawula ukuhamba kwamanzi. Ngokulungelelanisa i-angle ye-disc ngaphakathi kwevalve, izinga lokuhamba lingalawulwa ngokuchanekileyo. Oku kwenza ukuba iivalve zebhabhathane zisebenziseke kakhulu njengoko zinokusetyenziselwa ukulawula ukuhamba kolwelo kwiinkqubo ezahlukeneyo zemizi-mveliso, ukuqinisekisa ukusebenza kakuhle kunye nokusebenza kakuhle.

Ngamafutshane, umsebenzi weevalvu zebhabhathane, ngakumbi ezo zenziwe ngePVC, zibaluleke kakhulu kulawulo lolwelo lwamashishini. Ukukwazi kwayo ukulawula ukuhamba kolwelo, ukumelana neekhemikhali ezonakalisayo kunye nokubonelela ngenkonzo ethembekileyo kuyenza ibe yinxalenye ebalulekileyo kumashishini amaninzi. Nokuba zilawula ukuhamba kweekhemikhali ezonakalisayo kwindawo yokulungisa okanye zilawula ukuhanjiswa kwamanzi kwiinkqubo zikamasipala, izivalo zebhabhathane zePVC zidlala indima ebalulekileyo ekuqinisekiseni ukuba iinkqubo ezininzi zemizi-mveliso zihamba kakuhle nangempumelelo.
