1. He aha ke ano o ka wafer butterfly valve
Wafer Butterfly Valve: Ua hoʻolālā ʻia kēia ʻano valve e hoʻokomo ʻia ma waena o ʻelua flanges paipu, maʻamau he flange wafer.Loaʻa iā ia kahi hiʻohiʻona liʻiliʻi me kahi pā kīpē e hoʻohuli ai ma luna o kahi kumu e hoʻomalu i ke kahe.
ʻO nā pōmaikaʻi o ka wafer butterfly valve:
· He ʻano pōkole ka lōʻihi o ka pahu wafer-type butterfly, ʻo ia hoʻi, he ʻano lahilahi ia, e kūpono loa ai i nā kaiapuni me nā wahi liʻiliʻi.
· Hāʻawi lākou i ʻelua ala, pani paʻa a kūpono i nā ʻōnaehana me nā koi haʻahaʻa haʻahaʻa.
· ʻO ka pōmaikaʻi nui o ka pahu wafer butterfly kona hoʻolālā paʻa.

2. He aha ka flange butterfly valve
ʻO ka valve lele lele: He mau flanges koʻikoʻi ka flange butterfly valve ma nā ʻaoʻao ʻelua a hiki ke hoʻopaʻa pololei ʻia ma waena o nā flanges i ka pipeline.Ke hoʻohālikelike ʻia me nā ʻūhā pinch, ʻoi aku ka lōʻihi o ke kūkulu ʻana.
Nā pōmaikaʻi o ka valve butterfly flange:
· Aia i ka ʻūhā lele lele ka wēlau i hoʻopaʻa pololei ʻia i ka flange paipu.Hoʻonui kēia hoʻolālā i ka paʻa a me ka paʻa, kūpono ia no nā noi uila kiʻekiʻe kahi e koʻikoʻi ai nā pilina palekana.
· ʻOi aku ka maʻalahi o ka hoʻouka ʻana a me ka wehe ʻana i nā valve butterfly flange, no laila e maʻalahi ka mālama ʻana a me ka mālama ʻana i nā kumukūʻai.
· Hiki ke hoʻokomo ʻia ka valve butterfly flange ma ka hope o ka pipeline a hoʻohana ʻia ma ke ʻano he valve hopena.

3.He aha ka pahu lele lele flange hoʻokahi
ʻO ke ʻano o kakiwi lele lele hoʻokahiʻo ia ka loaʻa ʻana o kahi flange ma ka waena longitudinal o ke kino valve, pono e hoʻopaʻa ʻia ma ka flange o ka paipu me nā bolts lōʻihi.
Nā pōmaikaʻi o ka valve butterfly flange hoʻokahi:
· Loaʻa iā ia ka lōʻihi o ke ʻano o ka valve butterfly pipili a noho i kahi wahi liʻiliʻi.
· Ua like nā hiʻohiʻona pili paʻa me nā kiwi lele lele.
· He kūpono no nā ʻōnaehana haʻahaʻa haʻahaʻa.

1. Nā kūlana pili:
a) Wafer butterfly valve: ʻO kēia valve ka mea maʻamau maʻamau i hui pū ʻia a hiki ke kūpono me DIN PN6/PN10/PN16, ASME CL150, JIS 5K/10K, etc.
b) Flange butterfly valve: maʻamau hoʻokahi pili maʻamau.E hoʻohana wale i nā pili flange maʻamau.
c) Hoʻokahi puʻupuʻu lele flange: maʻamau, loaʻa kahi pilina maʻamau hoʻokahi.
2. Laulā nui
a) Wafer butterfly valve: DN15-DN2000.
b) Puka lele lele: DN40-DN3000.
c) Hoʻokahi flange butterfly valve: DN700-DN1000.
3. Hoʻokomo:
a) Ke hoʻokomo ʻana i nā ʻūhā wafer butterfly:
He mea maʻalahi ka hoʻonohonoho ʻana no ka mea hiki ke hoʻopaʻa ʻia ma waena o ʻelua flanges me ka hoʻohana ʻana i nā bolts stud lōʻihi.Ke hele nei nā bolts ma ka flange a me ke kino valve, hiki i kēia hoʻonohonoho ke hoʻokomo wikiwiki a wehe.
b) Ke hoʻokomo ʻana i ka valve butterfly flange:
No ka mea he mau flanges hoʻohui ʻia ma nā ʻaoʻao ʻelua, ʻoi aku ka nui o nā pulina flange a koi aku i kahi ākea.Hoʻopaʻa pololei ʻia lākou i ka flange paipu me nā studs pōkole.
c) Hoʻokomo ʻana i ka valve lele lele hoʻokahi:
pono nā kī poʻo ʻelua lōʻihi i hoʻopaʻa ʻia ma waena o nā ʻāpana ʻelua o ka paipu.Hōʻike ʻia ka helu o nā bolts i ka papa ma lalo nei.

4. Koina:
a) Wafer butterfly valve: Ke hoʻohālikelike ʻia me nā valve flange, ʻoi aku ka maikaʻi o nā ʻāpana wafer.ʻO ka lōʻihi o kā lākou hana pōkole e pono ai ka liʻiliʻi o nā mea a koi wale i ʻehā mau bolts, no laila e hōʻemi ana i nā kumukūʻai hana a hoʻokomo.
b) Flange Butterfly Valve: ʻOi aku ka nui o ke kumukūʻai o nā kīwī Flange ma muli o ko lākou kūkulu paʻa ʻana a me ka flange hoʻohui.ʻO nā bolts a me ka hoʻokomo ʻana i koi ʻia no nā pili flange ka hopena i nā kumukūʻai kiʻekiʻe.
c) Hoʻokahi flange butterfly valve:
ʻO ka pahu lele lele hoʻokahi-flange he hoʻokahi liʻiliʻi liʻiliʻi ma mua o ka lua-flange butterfly valve, a ʻoi aku ka maʻalahi o ka hoʻokomo ʻana ma mua o ka pahu pālua-flange butterfly valve, no laila aia ke kumukūʻai ma waena.
5. Ka pae kaomi:
a) Wafer butterfly valve: Ke hoʻohālikelike ʻia me ka flange valve, ʻoi aku ka haʻahaʻa o ka pae paʻi pili o ka wafer butterfly valve.Ua kūpono lākou no nā noi haʻahaʻa haʻahaʻa PN6-PN16.
b) Flange butterfly valve: Ma muli o kona ʻano paʻa a me ka flange integral, kūpono ka valve flange no nā kiʻekiʻe kiʻekiʻe o ke kaomi, PN6-PN25, (hiki i nā pahu lele i hoʻopaʻa ʻia i ka PN64 a i ʻole ke kiʻekiʻe).
c) Hoʻokahi pahu lele lele: ma waena o ka wafer butterfly valve a me ka flange butterfly valve, kūpono no nā noi PN6-PN20.
6. Noi:
a) Wafer Butterfly Valve: Hoʻohana mau ʻia i nā ʻōnaehana HVAC, nā mea kanu mālama wai a me nā noi ʻoihana haʻahaʻa haʻahaʻa kahi i kaupalena ʻia ai ka nui o ke kumukūʻai.No ka hoʻohana ʻana i nā ʻōnaehana paipu kahi i kaupalena ʻia a hiki ke ʻae ʻia nā hāʻule haʻahaʻa haʻahaʻa.Hāʻawi lākou i ka mana kahe wikiwiki a maikaʻi ma ke kumukūʻai haʻahaʻa ma mua o nā valve flanged.
b) Flange butterfly valve: Hoʻohana ʻia nā valve flange i nā ʻoihana e like me ka aila a me ke kinoea, ka hana kemika a me ka hana mana, kahi i koʻikoʻi ai nā pae kiʻekiʻe a me ka hana hoʻopaʻa sila maikaʻi.No ka mea hiki i nā kīwi lele flange ke hāʻawi i nā pae kiʻekiʻe o ke kaomi a me ka sila ʻoi aku ka maikaʻi a me nā pilina ikaika.A hiki ke hoʻokomo ʻia ka valve butterfly flange ma ka hope o ka pipeline.
c) Hoʻokahi flange butterfly valve:
Hoʻohana maʻamau ʻia nā kīpē flange butterfly hoʻokahi i nā ʻōnaehana wai o ke kūlanakauhale, nā ʻōnaehana ʻoihana e like me nā kemika, nā huahana petroleum a me nā wai ʻino ʻoihana, hoʻoponopono i ka hoʻomehana a i ʻole ka wai hoʻoluʻu i nā ʻōnaehana HVAC, ka mālama ʻana i ka wai, nā ʻoihana meaʻai a me nā ʻoihana ʻē aʻe.
ʻEKOLU.i ka hopena:
Loaʻa nā pono kūʻokoʻa a kūpono i nā ʻano hana like ʻole nā kīwī wafer butterfly, flange butterfly valves a me hoʻokahi flange butterfly valves.Hoʻohana ʻia nā ʻūhā wafer butterfly no ko lākou lōʻihi pōkole, hoʻolālā paʻa, hana kumukūʻai kiʻekiʻe a me ka hoʻonohonoho maʻalahi.He mea kūpono hoʻi nā ʻūhā lele lele hoʻokahi no nā ʻōnaehana haʻahaʻa haʻahaʻa me ka palena palena ma muli o ko lākou ʻano pōkole.ʻO nā valves Flanged, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maikaʻi i nā noi kiʻekiʻe e koi ana i ka hana hoʻopaʻa sila maikaʻi a me ka hana ʻino, akā ʻoi aku ka uku.
I ka pōkole, inā ua kaupalena ka paipu a me ka puʻe haʻahaʻa DN≤2000 ʻōnaehana, hiki iā ʻoe ke koho i kahi pahu wafer butterfly;
Inā kaupalena ka hoʻomaʻemaʻe paipu a ʻo ke kaomi ma waena a haʻahaʻa paha, 700≤DN≤1000, hiki iā ʻoe ke koho i hoʻokahi flange butterfly valve;
Inā lawa ka hoʻomaʻemaʻe paipu a ʻo ke kaomi ma waena a haʻahaʻa haʻahaʻa DN≤3000 ʻōnaehana, hiki iā ʻoe ke koho flange butterfly valve.
