Isikhululo sokuxuba i-asphalt sisiseko esibalulekileyo esipheleleyo sezixhobo kubomi babantu. Isixhobo sinezinto ezininzi, ezinjengomatshini wokulinganisa, isikrini esingcangcazelayo, i-belt feeder, isihambisi somgubo, ilifti kunye namanye amalungu. Ivalve yokuplaga nayo yenye yazo. Ke yintoni indima ethile yevalve yeplagi kwisityalo sokuxuba i-asphalt? Eli nqaku liza kunikela intshayelelo emfutshane elandelayo.

Ivalve yeplagi yeyokuqala kuzo zonke iluvalo okanye ivalve ejikelezayo emile okwe-plunger. Ngokuqhelekileyo, kufuneka ijikelezwe i-degrees ezingamashumi alithoba ukwenza i-port yeshaneli kwiplagi yevalve efana nomzimba wevalve, okanye inokwahlulwa ukuze ivule okanye ivale. isiphumo. Ubume bevalve yeplagi kwisityalo sokuxuba i-asphalt ngokuqhelekileyo i-cylinder okanye i-cone.

Ukuba umsebenzisi ubona umjelo oxande kwisityalo sokuxuba i-asphalt, ngokuqhelekileyo kwiplagi ye-valve ye-cylindrical. Ukuba ngumjelo wetrapezoidal, yiplagi yevalve ene tapered. Kwivalve yeplagi, izakhiwo ezahlukeneyo zonke zenza ulwakhiwo lube lula. Umsebenzi ophambili kukuvimba okanye ukudibanisa okuphakathi. Olunye usebenziso kukuphambukisa ukuhamba.

Iivalve zeplagi zikhawuleza kwaye kulula ukusebenza kwizityalo zokuxuba i-asphalt, ngoko ke ukusebenza rhoqo akuyi kubangela iingxaki. Iivalve zeplagi nazo zinezinye iimpawu, ezifana nokuchasana kwamanzi amancinci, isakhiwo esilula, ukugcinwa lula, ukusebenza kakuhle kokutywinwa kunye nokungabikho kwe-oscillation. Ingxolo ephantsi kunye nezinye iingenelo. Ukusetyenziswa kweeplagi zeplagi kwizityalo zokuxuba i-asphalt azikho izithintelo zolwalathiso kuyo yonke into, ngoko kuhlakaniphile kakhulu ukusebenzisa kwisixhobo.
