ʻO ka ili hoʻopaʻa o nā kiwi kila (DC341X-16 kiwi lele lele eccentric pālua) hana ʻia e (TWS valve) ka wili ʻana i luna. Hoʻokaʻawale ʻia nā mea i hoʻohana ʻia no ka hoʻoulu ʻana i ka valve i 4 mau ʻāpana nui e like me ke ʻano o ka hoʻohui ʻana, ʻo ia hoʻi nā ʻāpana cobalt-based, nickel-based alloys, iron-based alloys, and copper-based alloys. Hana ʻia kēia mau mea hao i loko o nā electrodes, nā uwea hoʻoheheʻe (me nā uea flux-cored), nā fluxes (me ka hoʻololi ʻana i ka alloy fluxes) a me nā pauka alloy, a me nā mea ʻē aʻe, a ke hoʻoheheʻe ʻia nei e ka wili lima arc, oxyacetylene flame welding, tungsten argon arc welding, submerged arc automatic welding a me plasma arc welding.
ʻO ke koho ʻana i nā mea e hoʻopili ai i ka ʻili o ka valve sealing surface (DC341X3-10ʻO ka pahu lele lele eccentric pāluakino sealing ring) e pili ana i ka wela o ka hoʻohana ʻana, ke kaomi hana a me ka corrosiveness o ka valve, a i ʻole ke ʻano o ka valve, ke ʻano o ka sealing surface, ka hoʻopaʻa ʻana i ke kaomi kikoʻī a me ke kaomi kikoʻī i ʻae ʻia, a i ʻole ka hana ʻana a me nā kūlana hana o ka ʻoihana, ka hiki ke hana o nā mea hana a me ka hiki ke ʻenehana o ka ihu a me nā koi o nā mea hoʻohana. Pono e hoʻohana ʻia ka hoʻolālā maikaʻi ʻia, a ʻo ka mea hoʻopaʻa paʻa me ke kumu kūʻai haʻahaʻa, ke kaʻina hana maʻalahi a me ka hana hana kiʻekiʻe e koho ʻia ma lalo o ke ʻano o ka hoʻokō ʻana i ka hana o ka （D341X3-16 ʻAilua ʻauwaʻa lele concentrice ) kiwikā.
Hoʻokahi wale nō ʻano o kekahi o nā mea i hoʻohana ʻia no ka hoʻopili ʻana i ka ʻili o ka valve sealing surface, a i ʻole electrode a i ʻole welding uea a i ʻole ka pauka alloy, no laila hiki ke hoʻohana ʻia i hoʻokahi ala i luna. Hana ʻia kekahi i mau koʻokoʻo wiliwili, nā uwea wili a i ʻole nā pauka alloy ma nā ʻano like ʻole, e like me ka stellite l 6 alloy, nā koʻokoʻo wiliwili ʻelua (D802), nā uwea welding (HS111) a me nā pauka alloy (PT2102), a laila wili lima lima, oxy2acetylene flame welding, tungsten argon arc welding, welding welding arc plasma arc. wiliwili. Ke koho ʻana i nā mea i hoʻokuʻu ʻia no ka ʻili o ka valve sealing, pono mākou e noʻonoʻo i ke koho ʻana i ke ʻano o ka ʻili me ka ʻenehana makua, ke kaʻina hana maʻalahi a me ka hana kiʻekiʻe o ka ʻoihana, i mea e hōʻoia ai i ka hoʻokō ʻana o kāna hana i ka hana ʻana o ka ʻili.
ʻO ka ʻili hoʻopaʻa ʻia ka ʻāpana nui o ka valve (D371X-10 Wafer butterfly valve), a pili pono kona maikaʻi i ke ola lawelawe o ka valve. ʻO ke koho kūpono o ka mea o ka valve sealing surface kekahi o nā ala nui e hoʻomaikaʻi ai i ke ola lawelawe o ka valve. Pono e pale ʻia nā kuhi hewa ʻole i ke koho ʻana i nā mea ili e hoʻopaʻa ai i ka valve sealing.
Manaʻo 1: ʻO ka paʻakikī o ka valve (D371X3-16C) he kiʻekiʻe ka mea hoʻopaʻa paʻa, a maikaʻi kona pale ʻana.
Hōʻike nā hoʻokolohua e hoʻoholo ʻia ke kūpaʻa ʻana o ka ʻili o ka valve sealing e ka microstructure o ka mea metala. ʻAʻole paʻakikī loa kekahi mau mea metala me ka austenite ma ke ʻano he matrix a me kahi ʻāpana liʻiliʻi o ka pae paʻakikī, akā maikaʻi loa ko lākou pale ʻana. He paʻakikī kiʻekiʻe ka paʻakikī o ka ili hoʻopaʻa ʻia e pale ai i ka hōʻeha ʻia a ʻoki ʻia e nā ʻōpala paʻakikī i ka waena. ʻO nā mea āpau i noʻonoʻo ʻia, kūpono ka waiwai paʻakikī HRC35 ~ 45.
Manaʻo 2: He kiʻekiʻe ke kumu kūʻai o ka valve sealing surface material, a maikaʻi kāna hana.
ʻO ke kumukūʻai o kahi mea waiwai kona ʻano waiwai ponoʻī, ʻoiai ʻo ka hana ʻana o ka mea i kona ʻano kino, ʻaʻohe pilina pono ma waena o nā mea ʻelua. ʻO ka metala cobalt i loko o nā mea hoʻoheheʻe ʻia i ka cobalt e hele mai ana mai ka lawe ʻana mai, a he kiʻekiʻe ke kumukūʻai, no laila ke kiʻekiʻe ke kumu kūʻai o nā mea hoʻohui i ka cobalt. Hōʻikeʻia nā'āpana Cobalt-based e ka pale lole maikaʻi i nā mahana kiʻekiʻe,ʻoiai ke hoʻohanaʻia i nā kūlana mahana maʻamau a me keʻano maʻamau, he kiʻekiʻe ke kumukūʻai / hana. I ke koho ʻana i nā mea e hoʻopaʻa ai i ka valve sealing surface, pono e koho ʻia nā mea me ke kumu kūʻai haʻahaʻa.
Manaʻo 3: Inā ʻoi aku ka maikaʻi o ka pale ʻana o ka ʻili o ka valve i loko o kahi ʻano corrosive ikaika, pono ia e hoʻololi i nā media corrosive ʻē aʻe.
ʻO ke kū'ēʻana o nā mea metala i konaʻano paʻakikī pono'ī, he mea maikaʻi ke kū'ēʻana i ka corrosion i loko o kahi meaʻeleʻele ikaika, a hoʻololi iki nā kūlana, e like me ka mahana a iʻole ka manaʻo waena, ua hoʻololiʻia ke kū'ēʻana. No kekahi mea ʻino ʻē aʻe, ʻoi aku ka nui o ka pale ʻana i ka corrosion. Hiki ke ʻike ʻia ke kūpaʻa ʻino o nā mea metala ma o nā hoʻokolohua, a pono e hoʻomaopopo ʻia nā kūlana kūpono no ke kuhikuhi ʻana mai nā mea kūpono, a ʻaʻole pono e ʻaiʻē makapō.
