ʻO ka hoʻohana ʻana o Titanium Alloy i ka ʻoihana Valve

He nui nā pōmaikaʻi o ka Titanium alloy e like me ka haʻahaʻa haʻahaʻa, ka ikaika kiʻekiʻe, ka pale ʻana i ka corrosion, ka wela kiʻekiʻe a me ke kūpaʻa haʻahaʻa haʻahaʻa, a hiki ke hoʻohana nui ʻia i nā kula he nui e like me ka petroleum, ʻoihana kemika, kai moana, biomedicine, aerospace, ʻoihana automotive, a me nā moku. . Loaʻa ka titanium alloy ma ka hoʻolei ʻana i ka titanium alloy i ke ʻano i makemake ʻia, ma waena o ka ZTC4 (Ti-6Al-4V) alloy ka mea i hoʻohana nui ʻia, me ka hana paʻa, ikaika maikaʻi a me ka paʻakikī fracture (ma lalo o 350 ℃).

Ma ke ʻano he mea hoʻomalu nui o nā ʻano kaiapuni kūikawā a me nā ʻōnaehana halihali pipeline wai kūikawā, ua lilo nā valves i mea koʻikoʻi o nā mea hana he nui, a hiki ke ʻōlelo ʻia ʻaʻole hiki i kekahi ʻoihana ke hana me ka ʻole o nā valve. Ma muli o ka ʻokoʻa o ke kaiapuni, ka mahana, a me nā koi ʻokoʻa i nā kula like ʻole, koʻikoʻi koʻikoʻi ke koho ʻana i nā mea valve. ʻO nā valves e pili ana i ka titanium alloys a me ka hoʻolei ʻana i ka titanium alloys he ākea ākea i ke kahua o nā valves ma muli o ko lākou kūpaʻa corrosion maikaʻi loa, hana kiʻekiʻe a haʻahaʻa haʻahaʻa, a me ka ikaika kiʻekiʻe.

- Moana
ʻO ke kaiapuni hana o ka ʻōnaehana paipu wai kai ʻoi loa ka paʻakikī, a ʻo ka hana ʻana o nā kīwaha moana e pili pono i ka palekana a me ka hana holoʻokoʻa o ka ʻōnaehana pipeline. I ka hoʻomaka ʻana o nā makahiki 1960, ua hoʻomaka ʻo Rūsia i ka noiʻi ʻana i nā alloys titanium no nā moku a hoʻomohala iā lākou no ka hoʻohana ʻana i ka moana β Titanium alloy i hoʻohana nui ʻia i nā ʻōnaehana pipeline moku kaua, e komo pū ana me nā kīwaha honua, nā kiwi hoʻopaʻa, a me nā kiwi pōlele, me nā ʻano like ʻole. a me ka nui o nā noi; I ka manawa like, ua hoʻohana pū ʻia nā valve titanium i nā ʻōnaehana pipeline moku kīwila. Ke hoʻohālikelike ʻia i nā ʻāpana keleawe i hoʻohana mua ʻia, ke kila, a me nā mea ʻē aʻe, ua hōʻike pū ʻia nā hoʻāʻo ʻana o ka wai i ka hoʻohana ʻana i ka titanium alloys i ka hilinaʻi kiʻekiʻe i nā ʻano he nui e like me ka ikaika a me ke kūpaʻa corrosion, a ua hoʻonui nui ʻia ke ola lawelawe, mai ka 2-5 mau makahiki a ʻoi aku ma mua o ʻelua, kahi i hoʻokipa nui ʻia e nā mea āpau. ʻO ka valve butterfly eccentric ʻekolu i hoʻolako ʻia e ka China Shipbuilding 725 Research Institute ma Luoyang, Kina no kekahi kumu hoʻohālike o ka moku, he hoʻololi ia i ke koho mua a me ka hoʻolālā hoʻolālā, me ka hoʻohana ʻana iā Ti80 a me nā mea ʻē aʻe e like me ke kino nui, e hoʻonui i ke ola lawelawe o ka valve ma luna o 25 mau makahiki, e hoʻomaikaʻi i ka hilinaʻi a me ka pono o nā noi huahana valve, a hoʻopiha i ka ʻenehana loea ma Kina.

- Aerospace
Ma ke kahua o ka aerospace, hana maikaʻi nā alloys titanium hoʻolei, mahalo i ko lākou kūpaʻa wela maikaʻi a me ka ikaika. ʻO ia hoʻi i ka makahiki 1960 i hoʻāʻo mua ai ʻo American Airlines i nā hoʻolei titanium. Ma hope o ka manawa o ka noiʻi, ua hoʻohana ʻia nā mea hoʻoheheʻe titanium i nā mokulele mai 1972 (Boeing 757, 767, a me 777, etc.). ʻAʻole wale i hoʻohana ʻia ka nui o nā mea hoʻoheheʻe titanium alloy, akā ua hoʻohana pū ʻia lākou i nā kūlana koʻikoʻi, e like me ka mana o ka valve i nā ʻōnaehana pipeline koʻikoʻi. ʻO nā valves maʻamau i hoʻohana ʻia me nā valves palekana, nā kiwi nānā, a me nā mea ʻē aʻe, ka mea i hoʻemi i nā kumukūʻai hana mokulele a hoʻonui i ka palekana a me ka hilinaʻi, ʻoiai, ma muli o ka liʻiliʻi liʻiliʻi a me ke kaumaha o ka titanium alloy i hoʻohālikelike ʻia me nā alloys ʻē aʻe, aia wale nō ma kahi o 60% o ʻO ke kila ikaika like, hiki i kāna noi ākea ke hoʻoikaika i ka mokulele e neʻe mau i ka ikaika kiʻekiʻe a me ke ala māmā. I kēia manawa, hoʻohana nui ʻia nā valve aerospace i nā ʻōnaehana mana he nui e like me ka pneumatic, hydraulic, fuel, a me ka lubrication, a ʻoi aku ka maikaʻi no nā kaiapuni me ke kūpaʻa corrosion a me ke kiʻekiʻe o ke kaiapuni. ʻO lākou kekahi o nā mea koʻikoʻi o nā kaʻa aerospace, nā mīkini, a me nā keʻena ʻē aʻe. Pono pinepine nā valve kuʻuna i ka hoʻololi ʻana, a ʻaʻole paha e hoʻokō i ka koi. I ka manawa like, me ka hoʻonui wikiwiki ʻana o ka mākeke valve aerospace, ke noho nei nā valves titanium i ka hoʻonui ʻana ma muli o kā lākou hana kiʻekiʻe.

- ʻOihana Kimia
Hoʻohana maʻamau ʻia nā valve kemika i nā wahi paʻakikī e like me ke kiʻekiʻe o ka wela, ke kiʻekiʻe kiʻekiʻe, ke kūpaʻa corrosion, a me ka ʻokoʻa nui. No laila, koʻikoʻi ke koho ʻana i nā mea kūpono no ka hoʻohana ʻana i ka ʻoihana kemika valve. I ka wā mua, koho nui ʻia ke kila kalapona, ke kila kila, a me nā mea ʻē aʻe, a hiki mai ka corrosion ma hope o ka hoʻohana ʻana, pono e hoʻololi a mālama. Me ka hoʻomau mau ʻana o ka hoʻolei ʻana i ka ʻenehana alloy titanium a ʻike ʻia kāna hana ʻoi aku ka maikaʻi, ua ʻike pū ʻia nā kīwaha titanium i nā maka o nā kānaka. ʻO ka lawe ʻana i ka ʻāpana hana o ka waikawa terephthalic i hoʻomaʻemaʻe ʻia (PTA) i ka ʻoihana fiber chemical ma ke ʻano he laʻana, ʻo ka mea hana ka nui o ka acetic acid a me ka hydrobromic acid, nona ka corrosiveness ikaika. Ma kahi kokoke i 8000 valves, me nā valves globe and ball valves, pono e hoʻohanaʻia, me nāʻano likeʻole a me ka helu nui. No laila, ua lilo nā valve titanium i koho maikaʻi, e hoʻonui ana i ka hilinaʻi a me ka palekana o ka hoʻohana. Ma ka laulā, ma muli o ka corrosiveness o ka urea, hiki i nā valve ma ka puka a me ka inlet o ka hale kiaʻi urea synthesis ke hoʻokō i ke ola lawelawe o 1 makahiki a ua hōʻea i nā koi hoʻohana. ʻO nā ʻoihana e like me Shanxi Lvliang Fertilizer Plant, Shandong Tengzhou Fertilizer Plant, a me Henan Lingbao Fertilizer Plant ua hana i nā hoʻāʻo he nui a ua koho hope loa i ka pahu titanium kiʻekiʻe-pressure check valve H72WA-220ROO-50, H43WA-220ROO-50, 65, 80, a me ka insulation. e hooki i na kiwi BJ45WA-25R-100, 125, a pela aku no ka lawe ana mai i na hale kiai urea synthesis, me ke ola o ka lawelawe ana ma mua o 2 makahiki, e hoike ana i ke ku'e'e kino maikai [9], e hoemi ana i ke alapine a me ke kumu kuai o ka pahu pani.

ʻAʻole i kaupalena ʻia ka hoʻohana ʻana o ka titanium alloy i ka mākeke valve i nā ʻoihana i ʻōlelo ʻia ma luna, akā aia ka hoʻomohala maikaʻi i nā ʻano ʻē aʻe. No ka laʻana, ʻo ka titanium alloy Ti-33.5Al-1Nb-0.5Cr-0.5Si hou i hoʻokumu ʻia ma Iapana he nui nā pono e like me ka haʻahaʻa haʻahaʻa, ka ikaika creep kiʻekiʻe, a me ke kūpaʻa maikaʻi. Ke hoʻohana ʻia i ka pahu hoʻopau hope o nā mīkini kaʻa, hiki iā ia ke hoʻomaikaʻi i ka hana palekana o ka mīkini a hoʻonui i kona ola lawelawe.

- Nā ʻoihana ʻē aʻe
Ke hoʻohālikelike ʻia me ka hoʻohana ʻana i nā alloys titanium cast i ka ʻoihana valve, ʻoi aku ka nui o nā noi ʻē aʻe o ka titanium alloys. ʻO ka Titanium a me ka titanium alloys he kūpaʻa maikaʻi loa i ka corrosion, he mea nui ia no nā ʻoihana me nā koi corrosive e like me ka ʻoihana petrochemical. I loko o kēia mau ʻoihana, nui nā mea hana nui e koi ai i ka hana ʻoihana e like me ka volumetric pumps, heat exchangers, compressors, a me nā reactors e hoʻohana i ka corrosion-resistant titanium castings, nona ka koi nui o ka mākeke. Ma ke kahua o ka lāʻau lapaʻau, ma muli o ka titanium i ʻike ʻia i ka honua palekana, non-toxic, a me ke koʻikoʻi metala manuahi, nui nā mea kōkua olakino, nā prostheses kanaka, a me nā mea ʻē aʻe i hana ʻia me nā alloys titanium. ʻOi loa i ka lāʻau lapaʻau niho, kokoke i nā mea hoʻolei niho āpau i hoʻāʻo ʻia i hana ʻia me ka titanium maʻemaʻe ʻoihana a me ka alloy Ti-6Al-4V, nona ka biocompatibility maikaʻi, nā waiwai mechanical, a me ka pale ʻana i ka corrosion. Ma ka ʻaoʻao ʻē aʻe, ma muli o ka maikaʻi o ka haʻahaʻa haʻahaʻa a me ka hana maikaʻi o ka titanium a me ka titanium alloys, ua hoʻohana nui ʻia lākou i nā mea haʻuki he nui e like me nā hui kolepa, nā poʻo kinipōpō, nā racket tennis, badminton rackets, a me nā mea lawaiʻa. ʻO nā huahana i hanaʻia mai ia mau mea he māmā, loaʻa ka hōʻoia maikaʻi, a kaulana loa i waena o ka lehulehu. No ka laʻana, hoʻohana ʻia ka SP-700 hou titanium alloy i hoʻomohala ʻia e Japan Steel Pipe Company (N104) ma ke ʻano he mea ʻili no Taylor brand 300 series kolepa poʻo kolepa, ʻo ia ka mea kūʻai maikaʻi loa ma ka mākeke kolepa honua. Mai ka hopena o ke kenekulia 20, ua hoʻokumu mālie nā alloys titanium i ka ʻoihana a me ka pālākiō i nā kula e like me ka petrochemical, aerospace, biomedical, ʻoihana automotive, a me nā haʻuki a me nā leʻaleʻa, mai ka ʻimi mua ʻana a hiki i ka hoʻolaha ikaika a me ka hoʻomohala ʻana.
