He ʻohana ʻo nā kīwi kīwī he hapaha-turn rotational motion valves i hoʻohana ʻia i nā pipelines, he nui nā ʻano ʻano kīpē lele. ʻO ka maʻamau, hoʻokaʻawale ʻia nā ʻano ʻokoʻa o nā kīwaha butterfly e nā pilina, nā mea,ʻano hana, kaʻina hana, a pēlā aku.ʻO ZFA kekahi o nā mea hana wafer butterfly valve kaulana, nā mea hana flange butterfly valve, a me nā mea hana lug butterfly valve ma Kina.
ʻO nā ʻano valve butterfly e ka Connection, ʻehā mau ʻano.
5. Weld butterfly valve
Aia ma lalo o ʻelima ʻano ʻano ʻano valve butterfly e nā mea kino valve.
1. Puka lele lele hao
2. Kiwi lele lele kalapona
3. Kiwikā lele lele
4. ʻAiʻina ʻaina kuhiliʻole kiwi lele lele
Aia ma lalo o ʻekolu mau ʻano nā ʻano kīpē kupu ma ke kaʻina hana no nā kino valve
1. Ka hoolei ana i ka valve lele
2. Kuʻikuʻi lele lele
3. Ke hoʻopaʻa ʻana i ka valve lele
Ke hoolei ana

Ke kalaiwa ana
ʻO nā ʻano ma ke ʻano hana, aia ma lalo o ʻelua ʻano.
1.ʻO ka ʻaupepa Lepepa waena
a. Pōmaikaʻi: ʻO ka hana maʻalahi a maʻalahi i ka hana ʻana, hoʻokele waiwai;
b. Nā pōʻino: ʻO ka pāpale butterfly a me ka noho valve i nā manawa a pau i ke kūlana o ka extrusion a me ka scraping, nui ka mamao kū'ē a wikiwiki ka lole.
c. Hoʻohana: Hoʻohana nui ʻia i nā kula he nui e like me ka petroleum, chemical, metallurgy, a me ka hydropower.
2.ʻO ka ʻūpepa Lepelele Eccentric
a. Pōmaikaʻi: Kū i ka wela kiʻekiʻe a me ke kaomi, Hoʻonui i ke ola o ka noho valve
b. Nā pōʻino: ʻO ke kumukūʻai a ʻoi aku ka paʻakikī o ka hana ʻana
c. Nā noi: Hoʻohana nui ʻia i loko o ka ʻōnaehana paipu wai o ka wai a me ka hoʻokaʻawale ʻana, ka wai, ka hana, ka ʻaila, kemika, ka lole māmā, ka hana pepa, hydropower, metallurgy, ikehu, a me nā papahana ʻē aʻe.
E noʻonoʻo kākou i nā loina kūpono a me ka mōʻaukala hoʻomohala ʻana o ka valve butterfly Centerline a me ka valve butterfly eccentric i nā kikoʻī.
Hōʻike ʻia ke kikowaena Butterfly Valve e ke kikowaena o ke koʻi kumu, ke kikowaena o ka pā butterfly, a me ke kikowaena o ke kino i ke kūlana hoʻokahi, e like me ke kikowaena kikowaena maʻamau. ʻO ka valve concentric butterfly, maʻamau mai ka nui DN50 a DN2200, ʻO ka hoʻopaʻa ʻana o ka valve butterfly laina waena he palupalu, no laila he haʻahaʻa haʻahaʻa a haʻahaʻa haʻahaʻa. ʻO ka ductile iron butterfly valve kekahi o ka concentric butterfly valve
Paʻi: DN
Mahana: E like me nā mea e hoʻopaʻa ai, No ka laʻana, NBR, Max wela: 100 ℃, EPDM, Max wela: 150 ℃; FRM, Max wela:200 ℃; SBR, Max wela: 100 ℃; CR, Max wela:100 ℃; NR, Max wela: 70 ℃; HR, Max wela: 100 ℃; UR, Ka wela kiʻekiʻe:40 ℃.
No ka valve butterfly eccentric, ʻekolu mau ʻano
a. Hoʻokahi Eccentric Butterfly Valve
b. Kiwikā lele lele lua
ʻO ka mōʻaukala o ke ʻano valve butterfly eccentric
ʻO ka valve eccentric butterfly hoʻokahi he ʻano o ka valve butterfly i hana ʻia no ka hoʻoponopono ʻana i ka pilikia o ke kaomi ʻana i ka pā papale a me ka noho kiwi ma ka laina waena. Hoʻokaʻawale ke koʻokoʻo mai ke kikowaena o ka valve butterfly i ʻole e lilo hou ka ʻaoʻao haʻahaʻa o ka valve butterfly i ke koʻi o ka hoʻololi ʻana, ka mea e hoʻopuehu a hoʻemi i ka hoʻoneʻe ʻana o nā ʻaoʻao luna a me lalo o ka pā papale a me ka noho valve.
ʻO ka valve butterfly offset pālua kekahi o nā ʻano valve butterfly, ʻo ke koʻi kumu ma waho o ke kikowaena o ka pā pepeke a me ke kikowaena o ke kino. ʻO ka hopena o ka lua eccentricity e hiki ai i ka papa pelelele ke wehe koke mai ka noho ma hope o ka wehe ʻana o ka valve, e kōkua ana i ka hoʻopau ʻana i ka nui o ka paʻi ʻana a me ka ʻoki ʻana ma waena o ka pā lele a me ka noho a hoʻomaikaʻi i ke ola o ka noho. ʻO ka hōʻemi nui ʻana o ka ʻōpala ʻana e hiki ai ke hoʻohana i nā noho metala no nā kīwaha butterfly eccentric pālua, hiki ke hoʻohana ʻia i nā noi wela kiʻekiʻe.
ʻO ka valve triple eccentric butterfly he ʻano ia o ka valve butterfly, no ka hoʻokaʻawale ʻana i ke kūlana axis stem i ka manawa like, e hoʻokaʻawale ana i ka axis conical o ka papa butterfly sealing surface mai ke koʻikoʻi cylindrical o ke kino, elliptical ka ʻili hoʻopaʻa o ka papa butterfly, ʻO ke ʻano o ka ʻili hoʻopaʻa ʻana no laila asymmetric, ʻo kekahi ʻaoʻao e kū i ka laina waena o ke kino, ʻo kekahi ʻaoʻao ua like. i ke kino waena.Ekolu eccentric butterfly valves e hoʻololi i ka ʻili o ka sila, ʻaʻole i hoʻonohonoho hou ʻia, akā ke hoʻopaʻa ʻana i ka torsion, e hilinaʻi ana i ka ʻili pili o ka noho valve e loaʻa ai ka hopena sealing, e hoʻonā i ka pilikia o ka leakage zero o ka noho valve metala. Ma muli o ka like o ke kaomi ʻana o ka ʻili a me ke kaomi waena, hoʻoponopono pū ia i ka pilikia o ke kaomi kiʻekiʻe a me ka wela kiʻekiʻe, a ʻoi aku ka nui o ka hoʻohana ʻana i ka valve butterfly.
