Eia ka hōʻuluʻulu manaʻo o ke anawaena o nā valves butterfly me nā ʻano hoʻohui like ʻole a me nā ʻano hana, e pili ana i nā kūlana ʻoihana maʻamau a me nā hana noi. No ka mea hiki ke ʻokoʻa ke anawaena kikoʻī ma muli o ka mea hana a me ka hiʻohiʻona noi (e like me ka pae kaomi, ʻano waena, a me nā mea ʻē aʻe), hāʻawi kēia ʻatikala i ka ʻikepili no nā kiwi zfa.
Eia ka ʻikepili kuhikuhi maʻamau i ke anawaena nominal (DN, mm).
1. Hoʻokaʻawale ʻia ke anawaena o nā kiwi lele ma ke ʻano pili
1. Wafer butterfly valve
- Anawaena laula: DN15–DN600
- ʻO ka wehewehe ʻana: He paʻa ke ʻano o nā kiwi wafer butterfly a hoʻohana pinepine ʻia i nā ʻōnaehana haʻahaʻa a haʻahaʻa. Loaʻa iā lākou kahi ākea ākea a kūpono i nā pipeline liʻiliʻi a me ka nui. Inā ʻoi aku ia ma mua o DN600, hiki iā ʻoe ke koho i hoʻokahi flange butterfly valve (DN700-DN1000). ʻO nā anawaena nui ʻē aʻe (e like me ka DN1200 ma luna aʻe) he kakaikahi ma muli o ke kiʻekiʻe o ka hoʻokomo ʻana a me nā koi sila.
2. ʻO ka pahu lele lele pālua
- Lae anawaena: DN50–DN3000
- ʻO ka wehewehe ʻana: He kūpono ka valve flange butterfly no nā manawa e koi ai i ke kūpaʻa kiʻekiʻe a me ka hana sila. ʻOi aku ka nui o ke anawaena a hoʻohana pinepine ʻia i nā ʻōnaehana pipeline nui e like me ka mālama wai, nā kikowaena mana, etc.
3. Hoʻokahi flange butterfly valve
- Anawaena laula: DN700–DN1000
- ʻO ka wehewehe ʻana: Hoʻopau nā kīwī flange hoʻokahi i nā mea liʻiliʻi ma mua o nā flange pālua a i ʻole nā pahu pahu, e hōʻemi ana i nā kumukūʻai hana a hoʻemi pū i nā kumukūʻai lawe. Hoʻopaʻa ʻia i ka flange paipu a hoʻopaʻa ʻia ma kahi.
4. Lug butterfly valve
- Lae anawaena: DN50–DN600
- ʻO ka wehewehe ʻana: He kūpono nā ʻūhā butterfly Lug (Lug type) no nā ʻōnaehana ma ka hopena o ka pipeline a i ʻole e koi pinepine i ka wehe ʻana. ʻO ke anawaena he liʻiliʻi a waena. Ma muli o nā palena hoʻolālā, ʻoi aku ka maʻamau o nā noi anawaena nui.
5. U-ʻano pepeke valve
- Ka laulā: DN100–DN1800
- Hōʻike: U-type butterfly valves ua hoʻohana nui ʻia no nā pipelines nui-diameter, e like me ka lako wai o ke kūlanakauhale, ka mālama ʻana i ka wai, a me nā mea ʻē aʻe.
| wehewehe | Ka nui maʻamau (DN) | ʻŌlelo Nui |
|---|---|---|
| ʻAupepa Pepa Wai | DN15-DN600 | ʻO ka hoʻolālā paʻa, uku-pono, hoʻohana nui ʻia i nā ʻōnaehana haʻahaʻa haʻahaʻa; nui nui no nā lawelawe koʻikoʻi ʻole. |
| Lug Butterfly Valve | DN50-DN600 | He kūpono no ka lawelawe make-end a me nā ʻōnaehana e koi ana i ka wehe ʻana mai kekahi ʻaoʻao. ʻOi aku ka maikaʻi ma mua o ke ʻano wai. |
| ʻO ka pāpaʻi kiʻi kiʻekiʻe-flanged | DN700-DN1000 | He mea maʻamau i nā ʻōnaehana i kanu ʻia a haʻahaʻa paha; ʻoi aku ka māmā a maʻalahi hoʻi e hoʻokomo. |
| Pane Lepe Lepa ʻAlua-Flanged | DN50-DN3000 (a hiki i DN4000 i kekahi mau hihia) | He kūpono no ke kaomi kiʻekiʻe, ke anawaena nui, a me nā noi koʻikoʻi; maikaʻi hoʻokō sila. |
| U-type Butterfly Valve | DN50-DN1800 | ʻO ka mea maʻamau i hoʻopaʻa ʻia a hoʻopaʻa ʻia paha no ka pale ʻana i ka corrosion i nā lawelawe kemika. |

2. Hoʻokaʻawale ʻia ke ʻano o nā kiwi lele ma ka ʻano hana
1. Kiwikā lele lele waena
- Lahi ʻo Caliber: DN50–DN1200
- Hōʻike: Centerline butterfly valve (seal soft seal or elastic seal) he ʻano maʻalahi, kūpono no ka haʻahaʻa haʻahaʻa a me ka media wela maʻamau, ka liʻiliʻi liʻiliʻi, a hoʻohana nui ʻia i ka wai, ke kinoea a me nā ʻōnaehana ʻē aʻe.
2. Kiwikā lele eccentric pālua
- Lahi ʻo Caliber: DN50–DN1800
- Hōʻike: ʻO ka valve eccentric butterfly ʻelua e hōʻemi i ka ʻaʻahu sila ma o ka hoʻolālā eccentric, kūpono no nā ʻōnaehana haʻahaʻa haʻahaʻa a me ke ʻano haʻahaʻa, he ākea ākea ākea, a hoʻohana mau ʻia i ka ʻaila a me ke kinoea, kemika a me nā ʻoihana ʻē aʻe.
3. ʻEkolu eccentric butterfly valve
- Ka laulā: DN100–DN3000
- Hōʻike: Triple eccentric butterfly valve (paʻa paʻa) kūpono no ka wela kiʻekiʻe, ke kaomi kiʻekiʻe a me nā kūlana hana paʻakikī. Loaʻa iā ia kahi ʻāpana caliber nui a hoʻohana pinepine ʻia i nā pipeline ʻoihana nui, e like me ka mana, petrochemical, etc.
| wehewehe | Laulā Nui | ʻŌlelo Nui |
|---|---|---|
| Pane Lepepa Concentric | DN40-DN1200 (a hiki i DN2000 i kekahi mau hihia) | ʻO ke kumu a me ka disc centerlines he alignent soft-seated kūpono no ka haʻahaʻa haʻahaʻa, nā noi maʻamau. |
| ʻO ka pāpaʻi pāpaʻi pālua Offset Butterfly | DN100-DN2000 (a hiki i DN3000) | Hoʻokuʻu koke ʻia ka disc mai ka noho ma ka wehe ʻana e hōʻemi i ka ʻaʻahu, hoʻohana ʻia i nā kūlana paʻakikī. |
| ʻEkolu Offset Butterfly Valve | DN100-DN3000 (a hiki i DN4000) | Hoʻolālā ʻia no nā noi kiʻekiʻe, kaomi-kiʻekiʻe, zero-leakage, maʻamau ka noho metala. |

Inā pono ʻoe e hāʻawi i nā ʻāpana kikoʻī hou aʻe no kahi ʻano kikoʻī a i ʻole ka inoa o ka valve butterfly, a i ʻole pono e hana i nā pakuhi kūpono, e ʻoluʻolu e wehewehe hou aku!
