ʻO Titanium B367 Gr.C-2 API maʻamau Flanged Butterfly Valve
ʻO ka ʻekolu offset e pili ana i ka hoʻohui ʻana i kahi eccentricity angular hou ma ke kumu o ka hoʻolālā eccentricity pālua i ʻōlelo ʻia ma luna, ʻoiai inā ʻo ka ʻili o ka pahu butterfly e hili a conical. ʻO ka hiʻohiʻona o kēia hana ʻo ia ka mīkini i ka ʻaoʻao o waho o ka pā pepeke i loko o kahi ʻili conical kūwaho, a e mīkini i ka ʻaoʻao o loko o ka noho valve sealing i loko o ka ʻili conical inclined. I kēia manawa, ua lilo ka ʻāpana hoʻopaʻa o ka valve butterfly elliptical, a ʻo ke ʻano o ka ili hoʻopaʻa ʻana o ka pā pelelele he asymmetrical. Ma muli o ka ʻili hoʻopaʻa conical conical, ua hoʻokaʻawale ʻia ka ʻaoʻao nui o ka pā peʻapeʻa e ke kumu o ka pahu valve a kaomi ʻia i luna i ka noho kiwi ma ka ʻili ākea nui, a ʻo ka ʻaoʻao liʻiliʻi o ka pā pepeke e kaomi ʻia i lalo i ka noho kiwi. ma ka ʻili liʻiliʻi liʻiliʻi. ʻAʻole hilinaʻi ʻia ka hoʻopaʻa ʻana ma waena o ke apo peʻa butterfly plate sealing a me ka noho valve i ka deformation elastic o ka noho valve, akā ma ke kaomi ʻana o ka ʻili pili e hoʻokō i ka sila. No laila, ʻaʻole frictionless ka wehe ʻana a me ka pani ʻana o ka valve eccentric butterfly, a i ka piʻi ʻana o ke kaomi pani ʻana, ʻoi aku ka paʻa o ka pahu.

ʻO ka valve butterfly eccentric ʻekolu, e like me ka crystallization o ka ʻenehana hou loa i nā valves, e hōʻike ana i nā ikaika o nā valves like ʻole a pale i nā nāwaliwali o nā ʻano valves, e loaʻa ʻole ka manaʻo nui mai nā mea hoʻohana a me nā mea hoʻolālā. Hiki i kona helu kiʻekiʻe ke piʻi i ka 2500 paona, hiki i ke anawaena maʻamau ke hiki i 48 iniha, a hiki ke hoʻohālikelike ʻia me nā clamps, lugs, flanges, apo ami, butt welds, jackets, like ʻole structural longs, etc. ʻO ke koho ʻana i nā mea, hiki ke hoʻopili manuahi ʻia me nā mahana kiʻekiʻe a me nā haʻahaʻa haʻahaʻa, a me nā ʻano media corrosive e like me ka waikawa a me ka alkali. ʻOi aku ma nā ʻōlelo o ke anawaena nui, me ka pono o ka leakage ʻole, ke hoʻololi mau nei ia i ka puka puka nui a me nā kiwi pōpō i nā kiwi pani. Pēlā nō, me kāna hana hoʻomalu maikaʻi loa, ke hoʻololi mau nei ʻo ia i nā puʻupuʻu honua nui i ka hoʻoponopono ʻana i nā kiwi. ʻO ka mea ʻoiaʻiʻo, hoʻohana ʻia ia i nā pipeline koʻikoʻi e like me ka hoʻokele kaʻina hana ma nā ʻoihana ʻoihana nui e like me ka ʻaila a me ka ʻili kinoea, nā kahua o waho, ka hoʻomaʻemaʻe aila, nā petrochemical, nā kemika inorganic, a me ka hana ikehu, me Kina. Hoʻohana nui ʻia ʻekolu mau ʻāpana butterfly eccentric i nā pipeline ʻoihana e like me ka metallurgy, ka mana, ka petrochemical, ka wai a me ka hoʻokaʻawale ʻana, a me ke kūkulu ʻana i ke kūlanakauhale kahi o ka mahana wela ≤ 425 ℃. Hoʻohana ʻia lākou e hoʻoponopono i ke kahe a ʻoki i ka wai.
