Nui nā ʻano okiwi lele, me ka oki wikiwiki a me ka hoʻoponopono mau.Hoʻohana nui ʻia no ka wai a me ke kinoea haʻahaʻa haʻahaʻa nui-diameter pipelines.He kūpono ia no nā manawa kahi i kiʻekiʻe ʻole ai nā koi o ke kaomi ʻana, koi ʻia ka hoʻoponopono kahe, a wikiwiki nā koi wehe a pani;ʻO ka mea maʻamau, aia ka mahana ma lalo o 300 ℃ a ʻo ke kaomi ma lalo o 40 kg (e hoʻohana maʻamau nā kīwaha butterfly i ka haʻahaʻa haʻahaʻa, e like me nā hale. a hiki ke hoʻohana pū ʻia ka medium granular.
Ma ke ʻano he valve butterfly i hoʻopaʻa ʻia, ua lawe mai ia i ka hoʻomohala wikiwiki ma hope o ka puka ʻana o ka synthetic rubber, no laila he ʻano hou ia o ka pahu pani pani.I koʻu ʻāina a hiki i ka makahiki 1980, ua hoʻohana nui ʻia nā ʻūlū butterfly no nā kīwī haʻahaʻa haʻahaʻa, a ua hana ʻia ka noho valve me ka ʻōpala synthetic.Ma ka makahiki 1990, ma muli o ka hoʻonui ʻia ʻana o ka hoʻololi ʻana me nā ʻāina ʻē, ua hoʻomohala wikiwiki ʻia nā kiwi lele paʻakikī (metal-seal).I kēia manawa, nui nā hale hana kiwi e hiki ai ke hana i nā kiwi lele lele i hoʻopaʻa ʻia i ka medium-pressure metala-sealed butterfly valves me ka paʻa, e hoʻonui ai i ke kahua noi o nā kiwi lele.
ʻO ka media e hiki ai i ka valve lele ke lawe a mālama ʻia, ʻo ia ka wai, ka wai i hoʻopaʻa ʻia, ka wai kaʻapuni, ka ʻili, ka wai kai, ka ea, ke kinoea, ke kinoea maoli wai, ka pauka maloʻo, ka lepo, ka slurry hua a me nā hui pū me nā mea paʻa paʻa.
He kūpono nā kiwi kīpē no ka hoʻoponopono kahe.Ma muli o ka nui o ka nalo ʻana o ka pahu lele i loko o ka pipeline, ʻoi aku ia ma kahi o ʻekolu manawa o ka valve.No laila, i ke koho ʻana i ka valve butterfly, pono e noʻonoʻo piha ʻia ka mana o ka nalowale o ka puʻuwai o ka ʻōnaehana pipeline.Pono e noʻonoʻo ʻia ka poho puʻe o ka pā peʻapeʻa ke pani ʻia ka pā pepeke.ʻO ka paʻa.Eia kekahi, pono e noʻonoʻo i ka palena o ka mahana hana e hiki ai i ka mea noho valve elastic ke kū i nā wela kiʻekiʻe.ʻO ka lōʻihi o ka lōʻihi a me ke kiʻekiʻe holoʻokoʻa o ka valve butterfly he liʻiliʻi, wikiwiki ka wehe a me ka pani ʻana, a he mau hiʻohiʻona maikaʻi kona.ʻO ke kumu hoʻolālā o ka valve butterfly ka mea kūpono loa no ka hana ʻana i nā kiwi nui-diameter.Ke koi ʻia ka valve butterfly e hoʻomalu i ke kahe ʻana, ʻo ka mea nui ke koho pololei i ka nui a me ke ʻano o ka valve butterfly i hiki ke hana pono a maikaʻi.
1. ʻO ka mea maʻamau, i ka throttling, hoʻoponopono i ka mana a me ka mud medium, pono ke kūkulu ʻia e pōkole i ka lōʻihi a me ka wikiwiki i ka wehe ʻana a me ka wikiwiki pani (1/4 revolution).ʻoki ʻoki haʻahaʻa haʻahaʻa (ka ʻokoʻa ʻokoʻa liʻiliʻi), ʻōlelo ʻia ka valve butterfly.
2. Hiki ke ho'ohana 'ia ka valve butterfly i ka ho'ololi 'ana i 'elua kūlana, ke kahawai ha'aha'a, ka leo ha'aha'a, ka cavitation a me ke kinoea, kahi li'ili'i o ka leakage i ka lewa, a loa'a ka media abrasive.
3. Ke hoʻohana ʻia ka valve butterfly ma lalo o nā kūlana kūikawā e like me ka throttling adjustment, a i ʻole nā ​​koi hoʻopaʻa paʻa paʻa, a i ʻole abrasion koʻikoʻi, haʻahaʻa haʻahaʻa (cryogenic) a me nā kūlana hana ʻē aʻe, pono e hoʻohana i kahi sila metala i hoʻolālā ʻia me kahi triple eccentric a i ʻole. ʻāpana hoʻololi eccentric pālua i hoʻolaʻa ʻia i ka valve butterfly no ka honua.
4. ʻO ke kikowaena butterfly valve ka mea kūpono no ka wai maʻemaʻe, ka wai, ka wai kai, ka wai paʻakai, ka mahu, ke kinoea maoli, ka meaʻai, ka lāʻau lapaʻau, a me ka ʻaila e pono ai ke hoʻopaʻa paʻa, ʻaʻohe kinoea hoʻāʻo leakage, ke ola lawelawe kiʻekiʻe, a me ka mahana hana o - 10 ℃~150 ℃.A me nā ʻakika like ʻole a me ka alkali a me nā pipeline ʻē aʻe.
5. ʻO ka valve butterfly eccentric i hoʻopaʻa ʻia i ka palupalu he mea kūpono ia no ka wehe ʻana a me ka pani ʻana a me ka hoʻoponopono ʻana i nā pipelines ventilation a me ka wehe ʻana o ka lepo, a hoʻohana nui ʻia i nā pipeline gas a me nā ala wai i ka metallurgy, ka ʻoihana māmā, ka mana uila, a me nā ʻōnaehana petrochemical.
6. ʻO ka uea metala e hoʻopaʻa ʻia i ka pahu pālua eccentric butterfly valve he kūpono ia no ka hoʻomehana ʻana o ke kūlanakauhale, ka hāʻawi ʻana i ka wai, ka wai a me nā kinoea ʻē aʻe, ka aila, ka waikawa a me nā paipu alkali, ma ke ʻano he mea hoʻoponopono a throttling.
7. Ma waho aʻe o ka hoʻohana ʻia ʻana e like me ka nui-nui puʻe swing adsorption (PSA) kinoea hoʻokaʻawale mea papahana mana kiwikā, ʻo Jinyong ka ʻili metala i hoʻopaʻa ʻia i triple eccentric butterfly valve hiki ke hoʻohana nui ʻia i ka petroleum, petrochemical, kemika, metallurgical, uila mana a nā kula ʻē aʻe.He ʻīpuka ʻīpuka a me ka pāpū honua.He huahana ʻokoʻa maikaʻi.
