Eia ka hōʻuluʻulu manaʻo o ka laulā o ke anawaena o nā kiwikā pepeke me nā ʻano hoʻohui like ʻole a me nā ʻano kūkulu, ma muli o nā kūlana ʻoihana maʻamau a me nā hana noi. ʻOiai ʻokoʻa paha ka laulā kikoʻī o ke anawaena ma muli o ka mea hana a me ke ʻano noi (e like me ka pae kaomi, ke ʻano waena, a pēlā aku), hāʻawi kēia ʻatikala i ka ʻikepili no nā kiwikā zfa.
Eia ka ʻikepili kuhikuhi maʻamau ma ke anawaena nominal (DN, mm).
1. Ka laulā o ke anawaena o nā kiwikā pepeke i hoʻokaʻawale ʻia e ke ʻano pili
1. kiwikā pulelehua Wafer
- Ka laulā o ke anawaena: DN15–DN600
- Wehewehe: He ʻano paʻa nā kiwikā pepeke wafer a hoʻohana pinepine ʻia i nā ʻōnaehana kaomi waena a me ke kaomi haʻahaʻa. Loaʻa iā lākou kahi laulā ākea a kūpono no nā paipu liʻiliʻi a me ka nui. Inā ʻoi aku ia ma mua o DN600, hiki iā ʻoe ke koho i kahi kiwikā pepeke flange hoʻokahi (DN700-DN1000). He mea kākaʻikahi nā anawaena nui loa (e like me DN1200 ma luna) ma muli o nā koi hoʻonohonoho a me ke sila kiʻekiʻe.
2. Pālua flange pulelehua kiwikā
- Ka laulā o ke anawaena: DN50–DN3000
- Wehewehe: He kūpono ka valve pepeke flange pālua no nā hanana e pono ai ke kūpaʻa kūkulu kiʻekiʻe a me ka hana sila. Loaʻa iā ia kahi laulā diameter nui a hoʻohana pinepine ʻia i nā ʻōnaehana pipeline nui e like me ka mālama wai, nā kikowaena mana, a pēlā aku.
3. Kiwikā pulelehua flange hoʻokahi
- Ka laulā o ke anawaena: DN700–DN1000
- Wehewehe: Hoʻopau nā kiwikā flange hoʻokahi i nā mea liʻiliʻi ma mua o nā kiwikā flange pālua a i ʻole nā kiwikā lug, kahi e hōʻemi ai i nā kumukūʻai hana a hōʻemi pū i nā kumukūʻai halihali. Hoʻopaʻa ʻia i ka flange paipu a hoʻopaʻa ʻia ma kahi.
4. Kiwikā pulelehua Lug
- Ka laulā o ke anawaena: DN50–DN600
- Wehewehe: He kūpono nā kiwikā pepeke lug (ʻano Lug) no nā ʻōnaehana ma ka hopena o ka pipeline a i ʻole e pono ai ka wehe pinepine ʻana. He liʻiliʻi a waena ka laulā o ke anawaena. Ma muli o nā palena kūkulu, ʻaʻole maʻamau ka hoʻohana ʻana i ke anawaena nui.
5. ʻO ka kiwikā pulelehua ʻano-U
- Ka laulā o ke ana: DN100–DN1800
- Wehewehe: Hoʻohana nui ʻia nā kiwikā pulelehua ʻano U no nā paipu anawaena nui, e like me ka hoʻolako wai kūlanakauhale, ka mālama ʻana i ka wai ʻino, a me nā mea ʻē aʻe, a kūpono ke ʻano no nā hiʻohiʻona kahe kiʻekiʻe a me nā ʻokoʻa haʻahaʻa haʻahaʻa.
| Wehewehena | Ka Pae Nui Maʻamau (DN) | Nā Memo Koʻikoʻi |
|---|---|---|
| Kiwikā Pulelehua Wai | DN15-DN600 | ʻAno paʻa, kūpono i ke kumukūʻai, hoʻohana nui ʻia i nā ʻōnaehana kaomi haʻahaʻa a waena; nā nui nui no nā lawelawe koʻikoʻi ʻole. |
| Kiwikā Pepeiao Lug | DN50-DN600 | Kūpono no ka lawelawe make a me nā ʻōnaehana e pono ai ke wehe ʻia mai kekahi ʻaoʻao. ʻOi aku ka maikaʻi o ka lawelawe ʻana i ke kaomi ma mua o ke ʻano wai. |
| Kiwikā Pulelehua Hoʻokahi-Flanged | DN700-DN1000 | Mea maʻamau i nā ʻōnaehana i kanu ʻia a i ʻole nā ʻōnaehana haʻahaʻa; māmā ke kaumaha a maʻalahi hoʻi e hoʻouka. |
| Pālua-Flanged Pepeiao Valve | DN50-DN3000 (a hiki i ka DN4000 i kekahi mau hihia) | Kūpono no nā noi kaomi kiʻekiʻe, ke anawaena nui, a me nā noi koʻikoʻi; hana sila maikaʻi loa. |
| Kiwikā Pulelehua ʻano U | DN50-DN1800 | ʻO ke ʻano maʻamau, ua uhi ʻia me ka laholio a i ʻole ua uhi piha ʻia no ke kūpale ʻana i ka pala i nā lawelawe kemika. |

2. Ka laulā Caliber o nā valves butterfly i hoʻokaʻawale ʻia e ke ʻano kūkulu
1. Kiwikā pepeke waena
- Ka laulā o ke ana: DN50–DN1200
- Wehewehe: He ʻano maʻalahi ka valve butterfly centerline (sila palupalu a sila elastic paha), kūpono no nā pāpaho haʻahaʻa a me nā pāpaho mahana maʻamau, ka laulā caliber waena, a hoʻohana nui ʻia i ka wai, ke kinoea a me nā ʻōnaehana ʻē aʻe.
2. Pālua kiwikā pepeke eccentric
- Ka laulā o ke ana: DN50–DN1800
- Wehewehe: Hoʻemi ka valve pepeke eccentric pālua i ka hoʻohana ʻana i ka sila ma o ka hoʻolālā eccentric, kūpono no nā ʻōnaehana kaomi haʻahaʻa a me ke waena, he ākea ka laulā caliber, a hoʻohana nui ʻia i ka aila a me ke kinoea, nā kemika a me nā ʻoihana ʻē aʻe.
3. ʻEkolu kiwikā pulelehua eccentric
- Ka laulā o ke ana: DN100–DN3000
- Wehewehe: ʻO ka valve butterfly eccentric ʻekolu (sila paʻakikī) he kūpono ia no ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe a me nā kūlana hana koʻikoʻi. Loaʻa iā ia kahi laulā caliber nui a hoʻohana pinepine ʻia i nā pipeline ʻoihana nui, e like me ka mana, ka petrochemical, a pēlā aku.
| Wehewehena | Pae Nui Maʻamau | Nā Memo Koʻikoʻi |
|---|---|---|
| Kiwikā Pulelehua Concentric | DN40-DN1200 (a hiki i ka DN2000 i kekahi mau hihia) | Hoʻonohonoho pono ʻia nā kikowaena o ke kumu a me ka diski me ke ʻano palupalu, kūpono no nā hana maʻamau a me ke kaomi haʻahaʻa. |
| Pālua Offset Pepeiao Valve | DN100-DN2000 (a hiki i ka DN3000) | Hoʻokaʻawale koke ka diski mai ka noho ma ka wehe ʻana e hōʻemi i ke komo ʻana, hoʻohana ʻia i nā kūlana kaomi waena. |
| Kiwikā Pepeiao Offset ʻEkolu | DN100-DN3000 (a hiki i ka DN4000) | Hana ʻia no nā noi mahana kiʻekiʻe, kaomi kiʻekiʻe, ʻaʻohe leakage, maʻamau i kau ʻia ma ka metala. |

Inā pono ʻoe e hāʻawi i nā palena kikoʻī hou aku no kahi ʻano kikoʻī a i ʻole ka brand o ka valve butterfly, a i ʻole pono e hana i nā pakuhi pili, e wehewehe hou aku!
