Okulandelayo isifinyezo sobubanzi bobubanzi bamavalvu ovemvane anezindlela ezihlukene zokuxhuma nezinhlobo zesakhiwo, ngokusekelwe kumazinga avamile embonini kanye nezinqubo zokusetshenziswa. Njengoba ububanzi obuthile bobubanzi bungase buhluke kuye ngomkhiqizi nesimo sohlelo (njengezinga lokucindezela, uhlobo olumaphakathi, njll.), lesi sihloko sihlinzeka ngedatha yamavalvu e-zfa.
Okulandelayo idatha yereferensi evamile ngobubanzi begama (DN, mm).
1. Ububanzi bobubanzi bamavalvu ovemvane ahlukaniswa ngendlela yokuxhuma
1. I-valve ye-butterfly ye-wafer
Ibanga lobubanzi: DN15-I-DN600
- Incazelo: Ama-valve evemvane eyi-Wafer ahlangene ngesakhiwo futhi avame ukusetshenziswa ezinhlelweni zokucindezela okuphakathi nendawo nokuphansi. Zinobubanzi obubanzi obubanzi futhi zifanele amapayipi amancane naphakathi nendawo. Uma idlula i-DN600, ungakhetha i-valve ye-butterfly eyodwa ye-flange (DN700-DN1000). Amadayamitha amakhulu ngokwengeziwe (njengangaphezulu kwe-DN1200) awavamile ngenxa yokufakwa okuphezulu nezidingo zokuvala.
2. I-valve ye-butterfly ephindwe kabili
- Ibanga lobubanzi: DN50-I-DN3000
- Incazelo: I-valve ye-butterfly ephindwe kabili ifanele izikhathi ezidinga ukuzinza okuphezulu kwesakhiwo nokusebenza kokuvala. Inobubanzi obukhulu be-diameter futhi ivame ukusetshenziswa ezinhlelweni zamapayipi amakhulu njengokuhlanza amanzi, iziteshi zikagesi, njll.
3. I-valve ye-butterfly ye-flange eyodwa
Ibanga lobubanzi: DN700-I-DN1000
- Incazelo: Ama-valve e-flange eyodwa adla izinto ezincane kune-double flange noma ama-lug valves, okunciphisa izindleko zokukhiqiza futhi anciphise nezindleko zokuhamba. Iboshelwe ku-flange yepayipi futhi iboshwe endaweni yayo.
4. Lug butterfly valve
- Ibanga lobubanzi: DN50-I-DN600
- Incazelo: Ama-valve butterfly we-Lug (uhlobo lwe-Lug) afanele amasistimu ekupheleni kwepayipi noma adinga ukuqaqa njalo. Ububanzi bobubanzi buncane futhi buphakathi. Ngenxa yemikhawulo yesakhiwo, izinhlelo zokusebenza ezinobubanzi obukhulu azivamile kangako.
5. I-valve ye-butterfly yohlobo lwe-U
Ibanga leCaliber: DN100-I-DN1800
- Incazelo: Amavalvu ovemvane ohlobo lwe-U asetshenziswa kakhulu kumapayipi anobubanzi obukhulu, njengokuphakelwa kwamanzi kamasipala, ukukhucululwa kwendle, njll.
| Incazelo | Ububanzi Bosayizi Ojwayelekile (DN) | Amanothi Abalulekile |
|---|---|---|
| I-Water Butterfly Valve | I-DN15-DN600 | Isakhiwo esiqinile, esingabizi kakhulu, esisetshenziswa kabanzi ezinhlelweni zokucindezela okuphansi kuya kokuphakathi; osayizi abakhulu bezinsizakalo ezingabalulekile. |
| I-Lug Butterfly Valve | I-DN50-DN600 | Ifanele isevisi yokuphela kwesikhathi namasistimu adinga ukuqaqa ohlangothini olulodwa. Ukuphatha ingcindezi kancane kunohlobo lwamanzi. |
| I-Single-Flanged Butterfly Valve | I-DN700-DN1000 | Okujwayelekile kumasistimu angcwatshwe noma anengcindezi ephansi; isisindo esincane futhi kulula ukuyifaka. |
| Ivaluvu Yevemvane Ephindwe Kabili | I-DN50-DN3000(kufika ku-DN4000 kwezinye izimo) | Ifanele ukucindezela okuphezulu, ububanzi obukhulu, kanye nezinhlelo zokusebenza ezibucayi; ukusebenza okuhle kakhulu kokufakwa uphawu. |
| Uhlobo lwe-U-Butterfly Valve | I-DN50-DN1800 | Ivamise ulayini werabha noma ulayini ophelele wokumelana nokugqwala kumasevisi amakhemikhali. |

2. Uhlu lwe-Caliber of butterfly valves oluhlukaniswa ngohlobo lwesakhiwo
1. I-Centerline butterfly valve
- Ibanga leCaliber: DN50-I-DN1200
- Incazelo: I-Centerline butterfly valve (i-soft seal noma i-elastic seal) inesakhiwo esilula, esilungele imidiya ephansi yokucindezela kanye nokushisa okujwayelekile, ububanzi obuphakathi, futhi isetshenziswa kabanzi emanzini, igesi nezinye izinhlelo.
2. I-valve yevemvane ene-eccentric kabili
- Ibanga leCaliber: DN50-I-DN1800
- Incazelo: I-valve ye-butterfly eyi-double eccentric inciphisa ukugqokwa kwe-seal ngokusebenzisa i-eccentric design, ifanele izinhlelo zokucindezela okuphansi nokuphakathi, inobubanzi obubanzi be-caliber, futhi ivame ukusetshenziswa kuwoyela negesi, amakhemikhali nezinye izimboni.
3. I-valve uvemvane eccentric kathathu
Ibanga leCaliber: DN100-I-DN3000
- Incazelo: I-valve ye-butterfly eccentric ephindwe kathathu (i-hard seal) ifanele izinga lokushisa eliphezulu, ukucindezela okuphezulu nezimo zokusebenza ezinzima. Inobubanzi obukhulu bezinga futhi ivame ukusetshenziswa kumapayipi amakhulu ezimboni, njengamandla, i-petrochemical, njll.
| Incazelo | Ibanga Losayizi Ojwayelekile | Amanothi Abalulekile |
|---|---|---|
| I-Concentric Butterfly Valve | I-DN40-DN1200 (kufika ku-DN2000 kwezinye izimo) | I-Stem kanye ne-disc centerlines zihambisana kahle-zihlezi kahle ezifanele ingcindezi ephansi, izicelo ezijwayelekile. |
| I-Double Offset Butterfly Valve | I-DN100-DN2000 (kufika ku-DN3000) | I-Disc ishesha ukuphuma esihlalweni ekuvulekeni ukuze kuncishiswe ukuguga, esetshenziswa ezimeni zokucindezela okumaphakathi. |
| I-Triple Offset Butterfly Valve | I-DN100-DN3000 (kufika ku-DN4000) | Idizayinelwe izinhlelo zokusebenza ezisezingeni eliphezulu, ezinomfutho ophezulu, ezivuza uziro, ngokuvamile ezihlala ngensimbi. |
