ʻO kekahi o nā mea koʻikoʻi e noʻonoʻo ai i ka hoʻolālā valve a me ke koho ʻana i nā mea waiwai ʻo ka mahana hana o ka valve. E hoʻohālikelike hou i ka mahana hana kūpono o nā mea kino kino valve, mai ka hana ʻana o ka helu concentric kila i hoʻohana ʻia i nā ʻano mea hana valve, ka mahana hana kūpono a me nā koi e pili ana i nā mea kino kino valve i hoʻohana ʻia i nā lako petrochemical home, nā mea kanu kemika, ʻO nā mea kanu kūlohelohe, ʻenehana mana uila a me nā ʻoihana metallurgical a me nā māla ʻē aʻe i kuhikuhi ʻia no ka hoʻolālā hiʻohiʻona, ka hana ʻana a me ka hoʻāʻo ʻana i nā huahana valve ʻAe. Eia kekahi, mai ka manaʻo o ka hoʻokele maikaʻi a me ka hoʻokele waiwai o ka ʻoihana a me ka loaʻa ʻana o nā mea waiwai, pono e koho ʻia kēlā me kēia kila like ʻole me ka hoʻokō ʻoi aku ka maikaʻi, ʻaʻole kūpono no ka hoʻohana ʻana i nā hiʻohiʻona kila me ka helu like, e pale ai i ka huikau.
1. ʻO ka mea nui o ka valve wela (-254(wai hydrogen) ~ -101 ℃(butadiene)) pono he kila haʻahaʻa, mea hao a i ʻole alumini alumini me ka lattice mau kino-centric. ʻO nā waiwai kino wela loa ma hope o ke kaʻina hana wela, ʻoi aku ka ikaika o ka haʻahaʻa haʻahaʻa haʻahaʻa e pono e hoʻokō i nā koi o ka maʻamau. Hiki ke hoʻohana ʻia nā mea hao haʻahaʻa haʻahaʻa e hana i nā kiwi wela wela. ASTMA351 CF8M, CF3M, CF8 a me CF3, ASTM A182F316, F316L, F304 a me F304L, ASTM A433 316, 316L, 304, 304L a me CF8D. ʻO ka pā aila kaapuni, ka pahu kahe hoʻokahi, ka ʻīpuka puka a i ʻole ka piston valve o ka wela wela e mālama i ka cryogenic i loko o ka wai nitrogen (-196 ℃) ma mua o ka hana hohonu.
2. Hoʻohana pinepine ʻia ka pahu kila wela kiʻekiʻe mau ʻo Cr-Mo e koho i ka WC6, WC9 a me C5 (ZG1Cr5Mo) ma ASTM A217 kikoʻī, a ʻo nā papa i ʻōwili ʻia ʻo F11, F22 a me F5 ma ASTM A182.
(1) Low chromium grade chrome-molybdenum kila he WC6, WC9, F11 a me F22, kona mea pili i ka wai, mahu a me radon kinoea, 'aʻole kūpono no ka sulfur maʻiʻo o ka aila hoʻomaʻemaʻe. Ua kūpono ʻo WC6 a me F11 no ka mahana hana o -29 ~ 540 ℃, a kūpono ʻo WC9 a me F22 no ka mahana hana o -29 ~ 570 ℃.
(2) C5(ZG1Cr5Mo) a me F5 chromium pentamolybdenum kiʻekiʻe wela kila, kona pili media no ka wai, mahu, radon kinoea a me ka sulfur maʻiʻo o ka aila hoʻomaʻemaʻe. C5(ZG1Cr5Mo) inā hoʻohana ʻia i loko o ka mahu wai, ʻo 600 ℃ kona wela hana kiʻekiʻe. ʻO ka mahana hana kiʻekiʻe loa ʻo 550 ℃ ke hoʻohana ʻia ia i ka ʻenehana e like me ka ʻaila sulfur content. No laila, pono ka mahana hana o C5(ZG1Cr5Mo) ma lalo o 550 ℃.
3, ʻo ke kumu nickel kūpaʻa i ka corrosion resistant nickel base kiʻekiʻe kiʻekiʻe o ka corrosion resistant nickel base alloy valve ke kī e hoʻohana ai i ka ASTM A494 kikoʻī o ka monel alloy forged.
(1), hoʻolei i ka nickel base alloy (CZ-100), Inconnel aluminum alloy (CY-40), Hastelloy alloy B(N-12MV, N-7M) a me Hastelloy C(CW-(1) Monel alloy Monel he ikaika kiʻekiʻe. a me ka ductibility, ʻoi aku ka maikaʻi o ke kūʻē ʻana i ka hoʻohaʻahaʻa ʻana i ka waikawa a me nā mea ʻawaʻawa ikaika a me nā waiwai ʻino o ke kai, no laila, hoʻohana maʻamau ia no ka hana ʻana a me ka lawe ʻana i ka waika hydrochloric, ka wai paʻakai, nā mea kūʻokoʻa, nā paʻakai alkali a me nā ʻakika oxidizing a me nā mea hana media a me nā kiwi. kūpono no ka maloʻo maloʻo a me ka manic hydrogen, hydrogen chloride gas, 425 ℃ mau kiʻekiʻe wela hydrogen a me 450 ℃ mau kiʻekiʻe kiʻekiʻe hydrogen chloride kinoea a me nā mea ʻē aʻe, akā ʻaʻole kūʻē i nā mea i loko o ka sulfur a me nā mea hoʻohaʻahaʻa (e like me ka sodium cyanide a me nā mea i loaʻa i ka oxygen. ) ʻinoʻino ʻO ka helu piha o ka pahu pahu o Monel alloy ʻo MM, a ʻo ka hapa nui ʻo Monel alloy valve ʻO ka code material valve o ke kila kalapona ʻo C/M, ʻo ka code material valve o CF8 ʻo P/M, a ʻo ka mea valve. ʻO ke code o CF8M he R/M. ʻO ka mahana hana kūpono o Monel M35-1, Monel 400 a me MonelK500 alumini alumini he -29 ~ 480 ℃.
(2) Cast nickel base alloy Cast nickel alloy (CZ-100) he 95%Ni a me 1100%C, a ʻaʻohe pā i ʻōwili ʻia. Loaʻa i ka CZ-100 ke kūpaʻa corrosion maikaʻi loa ke hoʻohana ʻia i ka hopena wela kiʻekiʻe me ka ʻike kiʻekiʻe a i ʻole ka wai a me ka alkali. Hoʻohana nui ʻia ʻo CZ-100 i ke kaʻina hana kemika chlor-alkali me ke kiʻekiʻe etching concentration (me ka hoʻoheheʻe ʻana i ka alumini chloride me ka wai ʻole a me ka anhydrous) a ma nā wahi i loaʻa ʻole ke keleawe a me ka hao a me nā mea hoʻohaumia ʻē aʻe metala. Hoʻolei ʻia ka nickel base alloy CZ-100 valve material code Ni. CZ-100 alumini alumini mea kūpono no ka hana ana wela o -29 ~ 316 ℃.
(3) ʻO Hastelloy Hastelloy ka inoa kālepa no Hastelloy, ʻo ia hoʻi ka hui pū ʻana, maʻamau ʻo Hastelloy B a me Hastelloy C i hoʻohana ʻia i loko o nā kiwi kū i ka corrosion. ʻO ka hoʻopili ʻana o Hastelloy B alloys i N-12MV(N-12M-1) a me N-7M (kekahi mau mea i kapa ʻia ʻo N-12M-2, ʻike ʻia hoʻi ʻo Chlorimet 2 alumini alumini) ma ASTM A494 ua ʻōwili ʻia i UNS ma ASTM B335 N10665 . Kūʻē ʻo Hastelloy B i ka waikawa sulfuric o nā ʻano a pau, a me nā paʻakai hoʻemi ʻole a me nā waikawa. Pono e koho ʻia ka valve pale corrosion o Hastelloy B, mai ke kūpaʻa ʻino a me ka noʻonoʻo ʻana i ka pale ʻana i ka corrosion haʻahaʻa haʻahaʻa Hastelloy B(N-7M). Helu waiwai Hastelloy ʻAʻohe koi i ke kahua valve. Hiki ke wehewehe pololei ʻia ka helu waiwai o Hastelloy B ma ka hana ʻana i ka helu hui. Ua kūpono ʻo Hastelloy B no ka mahana hana o -29 ℃ ~ 425 ℃.
