Okulandelayo isifinyezo sobubanzi bobubanzi bama-valve e-butterfly anezindlela ezahlukene zokuxhuma kanye nezinhlobo zesakhiwo, ngokusekelwe ezindinganisweni ezivamile zemboni kanye nemikhuba yokusetshenziswa. Njengoba ububanzi bobubanzi obuthile bungahluka kuye ngesimo somkhiqizi kanye nesicelo (njengezinga lokucindezela, uhlobo oluphakathi, njll.), lesi sihloko sinikeza idatha yama-valve e-zfa.
Okulandelayo idatha ejwayelekile yokubhekisela kububanzi obujwayelekile (i-DN, mm).
1. Ububanzi be-valve yebhabhathane buhlukaniswe ngendlela yokuxhuma
1. I-valve yebhabhathane ye-Wafer
- Ububanzi bebanga: DN15–I-DN600
- Incazelo: Amavalvu e-wafer butterfly aqinile ngesakhiwo futhi avame ukusetshenziswa ezinhlelweni zokucindezela okuphakathi nokuphansi. Anebanga elibanzi lobubanzi futhi afanele amapayipi amancane naphakathi. Uma edlula i-DN600, ungakhetha ivalvu ye-flange butterfly eyodwa (DN700-DN1000). Ama-diameter amakhulu kakhulu (njengalawo angenhla kwe-DN1200) awavamile ngenxa yezidingo eziphezulu zokufakwa nokuvalwa.
2. I-valve yebhabhathane ephindwe kabili
- Ububanzi bebanga: DN50–I-DN3000
- Incazelo: I-valve ye-butterfly ene-flange ephindwe kabili ifaneleka ngezikhathi ezidinga ukuzinza okuphezulu kwesakhiwo kanye nokusebenza kokuvala. Inebanga elikhulu lobubanzi futhi ivame ukusetshenziswa ezinhlelweni ezinkulu zamapayipi njengokwelashwa kwamanzi, iziteshi zikagesi, njll.
3. I-valve yebhabhathane elilodwa le-flange
- Ububanzi bebanga: DN700–I-DN1000
- Incazelo: Amavalvu e-flange eyodwa asebenzisa izinto ezincane kune-flange ephindwe kabili noma amavalvu e-lug, okunciphisa izindleko zokukhiqiza futhi kunciphisa nezindleko zokuhamba. Aboshelwa ku-flange yepayipi bese eboshelwa endaweni yawo.
4. I-Lug butterfly valve
- Ububanzi bebanga: DN50–I-DN600
- Incazelo: Amavalvu e-Lug butterfly (uhlobo lwe-Lug) afaneleka ezinhlelweni ezisekupheleni kwepayipi noma ezidinga ukuqaqwa njalo. Ububanzi bobubanzi buncane futhi buphakathi. Ngenxa yemikhawulo yesakhiwo, ukusetshenziswa kobubanzi obukhulu akuvamile.
5. Ivalvu yebhabhathane yohlobo lwe-U
- Ububanzi be-Caliber: DN100–I-DN1800
- Incazelo: Amavalvu ebhabhathane ohlobo lwe-U asetshenziswa kakhulu kumapayipi amakhulu, njengokuphakelwa kwamanzi kamasipala, ukwelashwa kwendle, njll., futhi isakhiwo sifanele izimo zokugeleza okuphezulu kanye nomehluko ophansi wokucindezela.
| Incazelo | Ububanzi Bosayizi Ovamile (i-DN) | Amanothi Ayisihluthulelo |
|---|---|---|
| I-Water Butterfly Valve | DN15-DN600 | Isakhiwo esincane, esisebenzisa kahle imali, sisetshenziswa kabanzi ezinhlelweni zokucindezela okuphansi kuya kokuphakathi; osayizi abakhulu bezinsizakalo ezingezona ezibalulekile. |
| I-Lug Butterfly Valve | DN50-DN600 | Ifanelekela isevisi engapheli kanye nezinhlelo ezidinga ukuhlukaniswa ohlangothini olulodwa. Ukuphathwa kwengcindezi kungcono kancane kunohlobo lwamanzi. |
| Ivalvu Yebhabhathane Ene-Flanged Eyodwa | DN700-DN1000 | Kuvamile ezinhlelweni ezimboziwe noma ezicindezelwe kancane; isisindo esilula futhi kulula ukuyifaka. |
| Ivalvu Yebhabhathane Ephindwe Kabili | DN50-DN3000 (kufika ku-DN4000 kwezinye izimo) | Ifanele ukusetshenziswa okunomfutho ophezulu, ububanzi obukhulu, kanye nezicelo ezibalulekile; ukusebenza kahle kokuvala. |
| I-U-type Butterfly Valve | DN50-DN1800 | Ngokuvamile irabha iboshwe noma iboshwe ngokuphelele ukuze imelane nokugqwala ezinkonzweni zamakhemikhali. |

2. Uhla lwe-caliber lwama-butterfly valve oluhlukaniswe ngohlobo lwesakhiwo
1. Ivalvu yebhabhathane eliphakathi nendawo
- Ububanzi be-Caliber: DN50–I-DN1200
- Incazelo: I-valve ye-butterfly ephakathi nendawo (uphawu oluthambile noma uphawu olunwebekayo) inesakhiwo esilula, esifaneleka kakhulu ezindaweni zokushisa eziphansi nezijwayelekile, ububanzi obuphakathi be-caliber, futhi isetshenziswa kabanzi emanzini, igesi nakwezinye izinhlelo.
2. Ivalvu yebhabhathane ephindwe kabili
- Ububanzi be-Caliber: DN50–I-DN1800
- Incazelo: I-valve ye-butterfly engavamile ephindwe kabili inciphisa ukuguguleka kwesivalo ngomklamo ongavamile, ifanele izinhlelo zokucindezela okuphansi nokuphakathi, inobubanzi obukhulu be-caliber, futhi ivame ukusetshenziswa embonini kawoyela negesi, amakhemikhali kanye neminye.
3. Ivalvu yebhabhathane eliyi-eccentric kathathu
- Ububanzi be-Caliber: DN100–I-DN3000
- Incazelo: I-valve ye-butterfly e-eccentric kathathu (uphawu oluqinile) ifaneleka ekushiseni okuphezulu, umfutho ophezulu kanye nezimo zokusebenza ezinzima. Inebanga elikhulu le-caliber futhi ivame ukusetshenziswa emapayipini amakhulu ezimboni, njengamandla kagesi, i-petrochemical, njll.
| Incazelo | Ububanzi Bosayizi Ovamile | Amanothi Ayisihluthulelo |
|---|---|---|
| I-Concentric Butterfly Valve | I-DN40-DN1200 (kufika ku-DN2000 kwezinye izimo) | Imigqa ye-stem kanye ne-disc ephakathi ihambisana kahle futhi ifanele ukusetshenziswa okujwayelekile, okunomfutho ophansi. |
| I-Valve ye-Butterfly ephindwe kabili | DN100-DN2000 (kufika ku-DN3000) | Idiski isuka ngokushesha esihlalweni lapho ivuleka ukuze inciphise ukuguguleka, isetshenziswa ezimweni ezicindezelayo. |
| I-Valve ye-Butterfly ye-Offset kathathu | DN100-DN3000 (kufika ku-DN4000) | Yakhelwe ukusetshenziswa kwezinga lokushisa eliphezulu, umfutho ophezulu, ukungavuzi lutho, ngokuvamile ehlala ensimbini. |
