I ke kamaʻilio ʻana e pili ana i ka valve butterfly, pono mākou e haʻi akukiwikā pulelehua wafera mekiwikā pulelehua flangeʻo ka mea mua, akā he aha ka ʻokoʻa ma waena o ka wafer a me ka flange butterfly valve? E papa inoa wau i kekahi mau helu ma lalo nei:
1. Wehewehena:
He aha nā Wafer Butterfly Valves?
Kiwikā Pepeiao Wafer: Ua hoʻolālā ʻia kēia kiwikā e kūpono ma waena o ʻelua mau flanges. Ua kapa ʻia lākou ʻo "wafer" no ka mea, ua like ko lākou ʻano lahilahi me kahi wafer. Pono mākou e hoʻokomo i ka wafer me nā wili stud lōʻihi, e holo ma waena o ka lōʻihi o ka kiwikā e hoʻopaʻa iā ia ma waena o nā flanges.
He aha nā Flange Butterfly Valves?
Kiwikā Pepeiao Flange: Loaʻa i kēia kiwikā kona mau flanges ponoʻī ma nā ʻaoʻao ʻelua o ke kino kiwikā, kahi i hoʻopaʻa ʻia i nā flanges like ma ka paipu.
2. Nā Kūlana Pili:
a) Wafer Butterfly Valve: ʻO kēia valve maʻamau no ka maʻamau multi-connection, no laila koho ka mea kūʻai aku e kūʻai i ke ʻano wafer ke ʻike ʻole ʻoe i ka pilina flange paipu.
b) Flange Butterfly Valve: ʻO ka flange butterfly valve maʻamau he pilina maʻamau hoʻokahi. Hiki iā ʻoe ke hoʻopili wale iā ia me nā flanges maʻamau e pili ana.
3. Noi:
a) Nā Wafer Butterfly Valves: Hoʻohana pinepine ʻia i nā noi wahi haiki a no nā ʻōnaehana kahi i maʻalahi ai ke kau ʻana. Kūpono no nā noi kaomi haʻahaʻa a waena.
b) Flanged Butterfly Valve: Inā loaʻa iā ʻoe kahi lawa e hoʻokomo ai i ka valve, ʻo ka flange type butterfly valve ke koho maikaʻi loa, no ka mea hiki iā ia ke hana me ke kaomi waena a kiʻekiʻe me ka ʻili sila paʻa.
4. Kumukūʻai:
a) Wafer Butterfly Valve: Ma keʻano laulā, ʻoi aku ka liʻiliʻi o ke kumukūʻai ma mua o nā flange valves ma muli o ko lākou hoʻolālā maʻalahi a me nā ʻāpana liʻiliʻi.
b) Flange Butterfly Valve: ʻO ka mea hou a me ka paʻakikī o ka hoʻolālā e hoʻolilo iā lākou i mea pipiʻi.
ʻO ke koho ʻana ma waena o kēia mau ʻano ʻelua o nā kiwikā pulelehua e pili ana i nā koi kikoʻī o ka noi, me nā palena o ka wahi, nā koi kaomi, ka alapine (frequency) o ka mālama ʻana, a me nā noʻonoʻo kālā.
ʻO ka hale hana kiwikā ʻo Zfa kahi hale hana kiwikā ʻano wafer me ka ʻoi aku o 15 mau makahiki o ka ʻike hana ʻana, e hāʻawi ana i ka kiwikā kiwikā wafer, ka kiwikā kiwikā flanged, ka kiwikā kiwikā lug, nā ʻāpana kiwikā e like me ke kino kiwikā, ka disc kiwikā, ka noho kiwikā a me ka lever lima kiwikā kiwikā kiwikā a pēlā aku. Aia kā mākou hui kūʻai aku ʻoihana ma ka pūnaewele no kāu nīnau.
