Ibikoresho bitandukanye byubushyuhe bwa valve ukoresheje ibikoresho bya valve ibyuma bidafite ibyuma bishyushye bizunguruka

Kimwe mubintu byingenzi bigomba kwitabwaho mugushushanya kwa valve no guhitamo ibikoresho ni ubushyuhe bwimikorere ya valve. Komeza usuzume ubushyuhe bukwiye bwibikoresho byumubiri wa valve, uhereye kumikorere yumubare wibyuma bikoreshwa mubwoko butandukanye bwibikoresho byubaka, ubushyuhe bukwiye bwakazi hamwe nibisabwa bijyanye nibikoresho byimyitwarire ya valve ikoreshwa mubikoresho bya peteroli yo murugo, inganda za chimique, ifumbire mvaruganda, amashanyarazi yinganda ninganda za metallurgjiya nizindi nzego zerekanwe kubishushanyo mbonera, gukora no kugerageza ibicuruzwa bya valve Yego. Uru rupapuro rwerekana cyane muburyo burambuye ubushyuhe bwubushyuhe, guhora hejuru yubushyuhe bwo hejuru, kwangirika kwa nikel base alloy ruswa irwanya nikel base alloy valve ibikoresho byatoranijwe ..
Kimwe mubintu byingenzi bigomba kwitabwaho mugushushanya kwa valve no guhitamo ibikoresho ni ubushyuhe bwimikorere ya valve. Komeza usuzume ubushyuhe bukwiye bwibikoresho byumubiri wa valve, uhereye kumikorere yumubare wibyuma bikoreshwa mubwoko butandukanye bwibikoresho byubaka, ubushyuhe bukwiye bwakazi hamwe nibisabwa bijyanye nibikoresho byimyitwarire ya valve ikoreshwa mubikoresho bya peteroli yo murugo, inganda za chimique, ifumbire mvaruganda, amashanyarazi yinganda ninganda za metallurgjiya nizindi nzego zerekanwe kubishushanyo mbonera, gukora no kugerageza ibicuruzwa bya valve Yego. Byongeye kandi, duhereye ku micungire y’ubuziranenge no gucunga umusaruro w’ibikorwa no gutanga amasoko, kuri buri cyuma gitandukanye kigomba gutoranywa hamwe n’imikorere yuzuye neza, kidakwiriye gukoreshwa n’icyuma kinini cyane gifite umubare umwe, kugirango wirinde urujijo.
1. Ibikoresho byingenzi byubushyuhe (-254 (hydrogène yamazi) ~ -101 ℃ (butadiene)) imyitwarire igomba kuba ibyuma bito bito, ibikoresho bivanze cyangwa aluminiyumu ivanze hamwe na lattice yumubiri uhoraho. Ubushyuhe bukabije bwa ultra-low physique nyuma yuburyo bwo kuvura ubushyuhe, cyane cyane ubukana bwa ultra-low ubushyuhe bukabije bugomba kuba bujuje ibisabwa mubisanzwe. Ibyuma bikurikira bikoreshwa cyane birashobora gukoreshwa mugukora ubushyuhe bwiza. ASTMA351 CF8M, CF3M, CF8 na CF3, ASTM A182F316, F316L, F304 na F304L, ASTM A433 316, 316L, 304, 304L na CF8D. Isahani yumuzingi wamavuta, icyuma kimwe gitemba, irembo cyangwa ama piston ya valve yubushyuhe bugomba kuba uburyo bwo kuvura korojeni muri azote yuzuye (-196 ℃) mbere yo gutunganywa byimbitse.
2. Umuvuduko ukabije wubushyuhe bwa Cr-Mo ikomeza ubushyuhe bwo hejuru bwicyuma gikunze gukoreshwa muguhitamo WC6, WC9 na C5 (ZG1Cr5Mo) mubisobanuro bya ASTM A217, kandi ibyapa bizunguruka ni F11, F22 na F5 muri ASTM A182.
. WC6 na F11 bikwiranye nubushyuhe bwakazi bwa -29 ~ 540 and, naho WC9 na F22 bikwiranye nubushyuhe bwakazi bwa -29 ~ 570 ℃.
(2) C5. C5 (ZG1Cr5Mo) iyo ikoreshejwe mumyuka y'amazi, ubushyuhe bwayo bukora ni 600 ℃. Ubushyuhe ntarengwa bwo gukora ni 550 ℃ iyo bukoreshejwe muburyo nkamavuta ya sulferi arimo amavuta meza. Kubwibyo, ubushyuhe bwo gukora bwa C5 (ZG1Cr5Mo) burasabwa kuba munsi ya 550 ℃.
3, ruswa irwanya nikel ishingiro ryubushyuhe bwo hejuru alloy ruswa irwanya nikel base alloy valve nurufunguzo rwo gukoresha ASTM A494 ibisobanuro bya monel alloy yahimbwe
(1). no guhindagurika, cyane cyane kurwanya cyane kugabanya aside nibintu bikomeye bya acide nibintu byangirika byo mu nyanja Kubwibyo, muri rusange bikoreshwa mugukora no gutwara aside hydrochloric, amazi yumunyu, ibintu bidafite aho bibogamiye, umunyu wa alkali hamwe na acide oxyde nibindi bikoresho byitangazamakuru hamwe na valve. bikwiranye na hydrogène yumye na manic, gaze ya hydrogène ya chloride, 425 ℃ ikomeza ubushyuhe bwo hejuru bwa hydrogène hamwe na 450 ℃ ikomeza ubushyuhe bwo hejuru bwa hydrogène chloride gaze nibindi bintu, ariko ntibirwanya ibintu birimo sulferi no kugabanya ibintu (nka sodium cyanide na ogisijeni irimo ogisijeni. ) kwangirika code ya CF8M ni R / M. Ubushyuhe bukwiye bwo gukora bwa Monel M35-1, Monel 400 na MonelK500 ya aluminiyumu ni -29 ~ 480 ℃.
. CZ-100 ifite imbaraga zo kurwanya ruswa iyo ikoreshejwe mugukomeza ubushyuhe bwo hejuru hamwe nubushyuhe bwinshi cyangwa nta mazi na alkali. CZ-100 ikoreshwa cyane mugikorwa cyo gutunganya imiti ya chlor-alkali hamwe nubushakashatsi bwinshi (harimo gushonga aluminium chloride idafite amazi na anhydrous) hamwe n’ahantu umuringa nicyuma nibindi bicuruzwa byangiza ibidukikije bidahari. Kora nikel base alloy CZ-100 valve ibikoresho code Ni. CZ-100 aluminiyumu ikwiranye n'ubushyuhe bwo gukora -29 ~ 316 ℃.
. Impimbano ya Hastelloy B ivanze na N-12MV (N-12M-1) na N-7M (ibikoresho bimwe na bimwe bita N-12M-2, bizwi kandi nka Chlorimet 2 aluminiyumu) ​​muri ASTM A494 byerekejwe muri UNS muri ASTM B335 N10665 . Hastelloy B irwanya aside sulfurike yibintu byose, kimwe no kutagabanya umunyu na aside. Umuyoboro urwanya ruswa ya Hastelloy B, uhereye ku kurwanya ruswa no gutekereza ku kurwanya ruswa ugomba guhitamo icyiciro cyo kurengera ibidukikije cya karuboni Hastelloy B (N-7M). Umubare wibikoresho bya Hastelloy Nta gisabwa mumurima wa valve. Umubare wibikoresho bya Hastelloy B urashobora gusobanurwa muburyo bwo guhimba nimero ihuriweho. Hastelloy B ibereye ubushyuhe bwakazi bwa -29 ℃ ~ 425 ℃.
