I-Leyon Hight Host Ars Aptil ductile i-duclil i-varve yesango

Izinto eziphambili

1. Isixhobo somzimba: Intsimbi ye-ductile
   • Inkcazo: Ibhulukhwe yevali yenziwa kwi-ductile intsimbi, umbandela onikezela amandla aphezulu e-thenle, ukuxhathisa kwempembelelo, kunye nokuguquguquka xa kuthelekiswa nentsimbi yesiko.
   • Izibonelelo:
     • Ukungaxhathisi okuphezulu kuxinzelelo loomatshini kunye nokothuka.
     • Uxinzelelo oluphezulu kunye nokuxhathisa kobushushu ngaphezu kwentsimbi engwevu.
     • Ukunganyangeki okungcono ukusulwa xa kudityanisiwe (umzekelo, nge-Epoxy Coating) yokusetyenziswa kweenkqubo zamanzi.
2. Isango (i-disc)
   • Inkcazo: Isango, elidla ngokubethwa yintsimbi yentsimbi, lingenziwa ngokupheleleyo kwi-tywer eyomeleleyo (irabha ye-EPDM) ukubonelela ngetywina eliqinileyo.
   • Izibonelelo:
     • Izinto ezikhoyo zivumela iqinile, itywina elivuzayo.
     • Ukunciphisa ukunxiba kunye nokukrazula kwimimandla yokutywina, ukuqina okukhulayo kunye ne-wossepan.
3. I-stem engeyiyo eyenyukayo (NRS)
   • InkcazoNgokungafaniyo nee vallo ezikhulayo, isiqu sihlala sihleli njengoko isango lisiya ezantsi.
   • Izibonelelo:
     • Uyilo olugcina indawo: Ilungele ufakelo kwizithuba ezivaliweyo okanye iinkqubo eziphantsi komhlaba apho indawo ethe nkqo inomda.
     • I-stem ye-stem ye-stems: Kuba intambo ingaphakathi kwi-veli yevali, ayinamdaka kumdaka, ukusula kunye nomonakalo woomatshini.
4. Isihlalo sokukhulisa
   • Inkcazo: Isihlalo sokukhulisa okwenziwa kwirabha (umz., EPDM), ebunjwe esangweni.
   • Izibonelelo:
     • Ibonelela ngei-titoff eqinileyoNgaphandle konxibelelwano lwensimbi ngentsimbi.
     • Ukunciphisa ukuvuza ukuvuza kwaye kubonelela nge-wospan ende ngenxa yokungaxhathisi baso kumanzi kunye nokuchitheka kwamanzi.
5. I-Bonnet kunye nenkqubo yokutywina
   • Inkcazo: I-bonnet idla ngokuvalelwa kwi-valve, ngenkqubo yokutywina usebenzisa i-o-rings okanye iigaza zokuthintela ukuvuza.
   • Izibonelelo:
     • Kulula ukukhululeka kulondolozo kunye nokulungiswa.
     • Ukutywinwa ngokufezekileyo ukuthintela ukuvuza kwibhunga le-valve.
6. Ukukhusela kunye nokukhusela i-corosion
   • Inkcazo: I-ductile i-valves idityaniswe neI-fusion-bous epoxy (FBE)okanye iingubo ezifanayo ukukhusela ukusulwa, ngakumbi kwiinkqubo zamanzi okusela.
   • Izibonelelo:
     • Inika ukumelana nokunganyangeki okuphezulu.
     • Iqinisekisa ukuthotyelwa kwemigangatho yokhuseleko lwamanzi (umzekelo, i-NSF / i-ANSI 61).
