A Ivalvu yebhola ye-intshi eyi-1 1/4sisixhobo esiguquguqukayo sokulawula ukuhamba kwamanzi esisetyenziswa kakhulu kwimizi-mveliso, ezorhwebo, nakwimisebenzi yezindlu. Uyilo lwayo oluncinci, ukuqina, kunye nokukwazi ukuphatha ulwelo olunoxinzelelo oluphezulu kwenza ukuba lube yimfuneko kwimibhobho, ioyile negesi, ukucubungula iikhemikhali, unyango lwamanzi, kunye neenkqubo ze-HVAC. Eli nqaku liphonononga umahluko weendleko zeevalvu zebhola eziyi-1 1/4 ngokusekelwe kwiintlobo zoqhagamshelo, izixhobo kunye nemithombo yokuvelisa, ngelixa ligxininisa usetyenziso lwazo oluphambili.
Izicelo zeIivalvu zeBhola ezi-1 1/4
Iivalvu zebhola eziyi-1 1/4 intshi zilawula ukuhamba kolwelo okanye iigesi kwibhola ejikelezayo enebhore. Ukusetyenziswa okuqhelekileyo kuquka:
- Imibhobho yemizi-mveliso: Ukulawula umphunga, iikhemikhali, okanye amafutha.
- Iinkqubo zamanziUkulawula amanzi okusela, ukunkcenkceshela, okanye amanzi amdaka.
- Iinkqubo ze-HVAC: Ukulungisa ukuhamba kwe-coolant kwiiyunithi zokufudumeza/zokupholisa.
- Ioyile kunye negesi: Ukwahlulahlula iindawo zemibhobho ukuze zilungiswe.
Ukuthembeka kwevalvu kwiindawo ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu kuyenza ibe lukhetho olukhethwayo kwimisebenzi ebalulekileyo.
Iinguqu zexabiso: Iintlobo zoQhagamshelo
Indlela yoqhagamshelwano inefuthe elikhulu kwixabiso le-Ivalvu yebhola eyi-1 1/4Apha ngezantsi kukho uthelekiso lweentlobo ezidumileyo:
| Uhlobo loQhagamshelo | Uluhlu lwamaxabiso (i-USD) | Ezona mpawu |
| Ivalvu yeBhola ye-NPT eyi-1 1/4 | $25 – $80 | Imisonto ethambileyo yokuvala ingavuzi. |
| Ivalvu yeBhola yeBW eyi-1 1/4 | $40 – $120 | Ifakwe nge-butt-welded kwiinkqubo ezihlala zihleli nezinoxinzelelo oluphezulu. |
| Ivalvu yeBhola yeSW eyi-1 1/4 | $30 – $100 | Uqhagamshelo lwesokhethi-weld kwiindawo ezincinci. |
| Ifakwe imisonto (BSP) | $20 – $70 | Ixhaphakile kwiimarike zaseYurophu naseAsia. |
- I-NPT vs. i-BSP: Imisonto ye-NPT (exhaphakileyo eMntla Melika) idla ngokubiza ngaphezulu nge-10–20% kune-BSP ngenxa yemigangatho yokuvelisa.
- I-Welded vs. I-ThreadedIivalvu ezidityanisiweyo (BW/SW) zibiza kakhulu kodwa zilungele iindawo ezinobungozi.
Ukwahluka kwamaxabiso: Iindidi zezinto ezibonakalayo
Ukukhethwa kwezinto ezisetyenzisiweyo kuchaphazela ukuqina, ukumelana nokugqwala, kunye neendleko. Apha ngezantsi kukho uhlalutyo:
| Izinto eziphathekayo | Uluhlu lwamaxabiso (i-USD) | Eyona ilungileyo |
| Ivalvu yeBhola yeBrass 1 1/4 | $20 – $60 | Iinkqubo zamanzi/zegesi ezinoxinzelelo oluphantsi. |
| Ivalvu yeBhola yeNtsimbi engaGciniyo eyi-1 1/4 | $50 – $150 | Ulwelo oludlakadlaka, olusetyenziswa kubushushu obuphezulu. |
| I-PVC | $15 – $40 | Ukuhambelana kweekhemikhali, kulula. |
- Yenziwe ngentsimbi eshayinayo: Ixabisa ngaphezulu kwe-2–3× kunethusi ngenxa yokumelana nokugqwala okuphezulu.
- Intsimbi yobhedu: Ixabiso eliphakathi, lifanelekile ukusetyenziswa ngokubanzi.
- I-PVC: Eyona ifikelelekayo kodwa inqunyelwe kwizicelo eziphantsi koxinzelelo.
Amaxabiso oMvelisi xa kuthelekiswa neFektri
Ukufumana ulwazi ngqo kwiUmvelisi weValve yeBholaokanyeumzi-mvelisoinokunciphisa iindleko nge-15–30%, ingakumbi kwiiodolo ezinkulu. Nangona kunjalo, iivalvu ezinophawu (umz.,Ivalvu yeBhola yeApollo, Ivalvu yeBhola yeSwagelok) inokuba neprimiyamu yomgangatho oqinisekisiweyo. Izinto ezibalulekileyo ekufuneka uziqwalasele:
1. Ii-MOQ (Ubuncinane boBuninzi boku-odola)Iifektri zihlala zifuna iiodolo ezinkulu.
2. Ukwenziwa ngokwezifiso: Abavelisi banokuhlawulisa imali eyongezelelweyo ngeenkcukacha ezingezizo ezisemgangathweni.
3. IziqinisekisoIivalvu eziqinisekisiweyo yi-ISO zibiza ngaphezulu nge-10–15%.
Isiphelo
Ixabiso leIvalvu yebhola eyi-1 1/4Iqala kwi-$15 kwiimodeli zePVC ezisisiseko ukuya kwi-$150+ kwiintlobo zentsimbi engagqwaliyo okanye ezidityanisiweyo.
