I. Nā Kumumanaʻo no ke Koho ʻanaNā kiwikā pulelehua
1. Koho ʻano hoʻonohonoho
Kiwikā pulelehua waena (ʻano laina waena):He kūlike ke kumu o ka valve a me ka disc butterfly ma ke kikowaena, me ka hoʻonohonoho maʻalahi a me ke kumukūʻai haʻahaʻa. Hilinaʻi ke sila ʻana ma luna o ka sila palupalu rapa. He kūpono ia no nā hanana me ka mahana a me ke kaomi maʻamau a ʻaʻohe koi koʻikoʻi.
Kiwikā pulelehua eccentric hoʻokahi:Ua hoʻokaʻawale ʻia ke koʻokoʻo valve mai ke kikowaena o ka disc butterfly, e hōʻemi ana i ka friction ma waena o nā ʻili sila i ka wā o ka hana a hoʻolōʻihi i ke ola lawelawe. Kūpono no nā noi waena a me ke kaomi haʻahaʻa e pono ai ka wehe pinepine a me ka pani ʻana.
Kiwikā pulelehua eccentric pālua (kiwikā pulelehua hana kiʻekiʻe):Ua hoʻokaʻawale ʻia ke kumu valve mai ka disc butterfly a me ke kikowaena o ka ʻili sila, e hiki ai ke hana me ka ʻole o ka friction. Loaʻa pinepine iā ia ka sila metala a i ʻole ka hui pū ʻana. Kūpono no nā mea wela kiʻekiʻe, kaomi kiʻekiʻe, corrosive, a i ʻole particulate.
ʻEkolu-eccentric butterfly valve:Ke hoʻohui nei i ka eccentricity pālua me kahi hui sila conical beveled, hoʻokō ia i ka ʻole o ka friction a me ka ʻole o ka leakage, me ke kūpaʻa wela kiʻekiʻe a me ke kaomi kiʻekiʻe. Kūpono no nā kūlana hana koʻikoʻi (e laʻa, mahu, aila/kinoea, media wela kiʻekiʻe).
2. Koho ʻano hoʻokele
Puke lima:no nā anawaena liʻiliʻi (DN≤200), ke kaomi haʻahaʻa, a i ʻole nā kūlana hana pinepine ʻole.
Hoʻokele ilo:Kūpono no nā noi anawaena waena a nui e pono ai ka hana maʻalahi a i ʻole ke hoʻoponopono ʻana i ke kahe ʻana.
Pneumatic/Uila:ʻO ka mana mamao, nā ʻōnaehana automation, a i ʻole nā koi pani wikiwiki (e laʻa, nā ʻōnaehana hoʻāla ahi, nā pani ulia pōpilikia).
3. Nā mea sila a me nā mea hana
Sila palupalu (laholio, PTFE, a pēlā aku): sila maikaʻi, akā palena ka pale ʻana i ka mahana a me ke kaomi (maʻamau ≤120°C, PN≤1.6MPa). Kūpono no ka wai, ka ea a me nā mea palaho nāwaliwali.
Nā sila hao (kila kila, carbide sima): Ke kūpaʻa wela kiʻekiʻe (a hiki i ka 600°C), ke kaomi kiʻekiʻe, a me ke kūpaʻa i ka ʻaʻahu a me ka pala, akā ʻoi aku ka haʻahaʻa o ka hana sila ma mua o nā sila palupalu. Kūpono no nā mea hana wela kiʻekiʻe i ka metallurgy, nā mea kanu mana, a me nā petrochemicals.
Mea kino: Hao hoʻolei ʻia, kila kalapona, kila kila ʻole, kila huila, a i ʻole ka uhi plastik/laho ma muli o ka ʻino o ka mea.
4. Ka pae o ke kaomi a me ka mahana:
Hoʻohana nui ʻia nā kiwikā pepeke palupalu no PN10 ~ PN16, me nā mahana ≤120 °C. Hiki i nā kiwikā pepeke i sila ʻia metala ʻekolu-eccentric ke piʻi ma luna o PN100, me nā mahana ≥600 °C.
5. Nā ʻano o ke kaʻahele
Ke koi ʻia ka hoʻoponopono ʻana o ke kahe ʻana, koho i kahi kiwikā pulelehua me nā ʻano kahe linear a like paha o ka pakeneka (e laʻa, disc ʻano V).
6. Kahi hoʻonohonoho a me ke kuhikuhi kahe:He ʻano paʻa ko ka valve butterfly, e kūpono ai no nā pipeline me kahi palena. Ma keʻano laulā, ʻaʻohe palena o ke kuhikuhi kahe, akā no nā valve butterfly ʻekolu-eccentric, pono e kuhikuhi ʻia ke kuhikuhi kahe.
II. Nā Hana Kūpono
1. Nā ʻōnaehana mālama wai a me ka hoʻolako wai a me ka hoʻokahe wai: Hoʻolako wai kūlanakauhale, paipu pale ahi, a me ka mālama ʻana i ka wai ʻino: hoʻohana pinepine ʻia nā kiwikā butterfly centerline palupalu, he haʻahaʻa ke kumukūʻai a he sila pono hoʻi. No nā puka pamu a me ka hoʻoponopono kahe: koho i nā kiwikā butterfly gear a i ʻole nā kiwikā butterfly mana uila.
2. Nā paipu petrochemical a me ke kinoea kūlohelohe: Ua koho ʻia nā kiwikā pepeke i hoʻopaʻa ʻia me ka metala ʻekolu-eccentric no ke kūpaʻa ʻana i ke kaomi kiʻekiʻe a me ka pale ʻana i ka leaka. Nā mea hana ʻino (e laʻa, nā waikawa/alkalis): Hoʻohana ʻia nā kiwikā pepeke i hoʻopaʻa ʻia me ka fluorine a i ʻole nā kiwikā metala pale i ka corrosion.
3. No ka ʻoihana mana, nā ʻōnaehana wai e kaapuni ana, a me ka desulfurization kinoea flue: nā kiwikā pepeke i hoʻopaʻa ʻia me ka laholio eccentric waena a pālua paha. No nā paipu mahu (e laʻa, nā ʻōnaehana lako kōkua i nā mea kanu mana): ʻekolu mau kiwikā pepeke i hoʻopaʻa ʻia me ka metala eccentric.
4. Nā ʻōnaehana hoʻolaha wai anuanu a me ka wai wela o HVAC (Hoʻomehana, Hoʻoulu ʻia ka ea, a me ke ea): nā kiwikā pepeke i sila palupalu ʻia no ka kaohi ʻana i ke kahe a i ʻole ka ʻoki ʻana.
5. No nā paipu ʻenekinia moana a me nā paipu wai kai: nā kiwikā pulelehua kila kila duplex kūpaʻa i ka palaho a i ʻole nā kiwikā pulelehua i uhi ʻia i ka laholio.
6. Hoʻokō nā kiwikā pepeke meaʻai a me nā kiwikā lapaʻau (kila kila i wili ʻia, nā mea hoʻohui wikiwiki) i nā koi sterile.
7. Lepo a me nā mea ʻōpala ma nā kūlana hana kūikawā: Paipai ʻia nā kiwikā pepeke paʻa-paʻa e pale aku i ka ʻaʻahu (e laʻa, no ka lawe ʻana i ka pauka mine).
ʻŌnaehana hoʻoheheʻe wai: Hoʻoheheʻe wai kūikawākiwikā pepekehōʻoia i ka hana sila.
III. Hopena
TWSʻaʻole wale ia he hoa hilinaʻi no ke kūlana kiʻekiʻenā kiwikā pepekeakā ke kaena nei hoʻi i ka ʻike loea nui a me nā hoʻonā i hōʻoia ʻia manā kiwikā puka, nā kiwikā nānā, a menā kiwikā hoʻokuʻu eaʻOiai he aha kāu mau koi kaohi wai, hāʻawi mākou i ke kākoʻo valve ʻoihana, hoʻokahi-kū. No nā hui like ʻana a i ʻole nā nīnau loea, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa.
