Imipira 4 gukomera
Icyicaro cyingenzi cyo gufunga ibikoresho byaimipirani polytetraoxyethylene (PTFE), yunvikana mubintu hafi ya byose byimiti, kandi ifite coeffisiyonike nkeya, imikorere ihamye, ntabwo yoroshye gusaza, ubushyuhe bwagutse bwikigereranyo hamwe nibikorwa bya kashe Byiza biranga ibintu byuzuye.Nyamara, ibintu bifatika bya PTFE, harimo coefficient yo kwaguka cyane, kumva neza imbeho ikonje ndetse nubushyuhe buke bwumuriro, bisaba gushushanya kashe ya kashe kugirango yibande kuri ibyo biranga.Ibikoresho bya pulasitike bya kashe ya valve nayo irimo PTFE yuzuye, nylon nibindi bikoresho byinshi.Ariko, mugihe ibikoresho byo gufunga bigoye, ubwizerwe bwa kashe buzangirika, cyane cyane mugihe itandukaniro ryumuvuduko muke.Byongeye kandi, reberi yubukorikori nka butyl reberi irashobora kandi gukoreshwa nkibikoresho bifunga intebe ya valve, ariko imiti ikoreshwa nubushyuhe bwo hagati nubushyuhe.Byongeye kandi, niba uburyo budasizwe amavuta, gukoresha reberi yubukorikori birashoboka guhuza umupira.
Kugirango huzuzwe ibisabwa gukoreshwa mubikorwa byinganda nkubushyuhe bwo hejuru, umuvuduko mwinshi, isuri ikomeye, kuramba, nibindi, imipira yumupira ifunze ibyuma byatejwe imbere mumyaka icumi ishize.By'umwihariko mu bihugu byateye imbere mu nganda, nka Amerika, Ubutaliyani, Ubudage, Espagne, Ubuholandi, n'ibindi, imiterere y’umupira w’umupira yagiye ikomeza kunozwa, kandi habayeho umubiri wose wasudishijwe umubiri ushyinguwe neza n’umupira w’umupira, guterura imipira yumupira, hamwe numupira wumupira mumiyoboro ndende, ibikoresho byo gutunganya amavuta, nibindi. Uruganda rwinganda rurakoreshwa cyane, hamwe na diameter nini (3050mm), umuvuduko mwinshi (70MPa) nubushyuhe bwagutse (-196 ~ 8159C) imipira yumupira igaragara, kuburyo tekinoroji yumupira wumupira igeze kurwego rushya.
5 Umupira wa valve gushushanya no gukora
Bitewe no gukoresha mudasobwa ifashwa na mudasobwa (CAD), Computer Aided Manufacturing (CAM) na Mulberry Manufacturing Sisitemu (FMS) mu nganda za valve, gushushanya no gukora imipira yumupira bigeze kurwego rushya.Ntabwo yahinduye gusa uburyo bwo kubara igishushanyo mbonera cya valve, ahubwo yanagabanije imirimo iremereye kandi isubirwamo yibikorwa bisanzwe byabakozi babigize umwuga na tekiniki, kuburyo abatekinisiye bafite imbaraga nyinshi zo kunoza, kunoza imikorere yibicuruzwa no guteza imbere ibicuruzwa bishya, no kugabanya ubushakashatsi no iterambere ryibicuruzwa bishya., Kongera umusaruro wumurimo muburyo bwose, kandi mugikorwa cyubushakashatsi niterambere ryoguterura inkoni yubwoko bwicyuma gifunga umupira wa valve, kubera ikoreshwa rya CAD / CAM, igorofa nini yagutse ikozwe na mudasobwa hamwe na mudasobwa -ibikoresho bya mashini ya CNC byagaragaye, ni kashe yicyuma.Umuyoboro wumupira ntugushushanya kandi wambara mugihe cyo gufungura no gufunga, kuburyo imikorere yo gufunga hamwe nubuzima bwa serivise yumupira wumupira byateye imbere cyane.Iyo umupira wumupira ufunguye byuzuye, kurwanya umuvuduko ni muto cyane, hafi ya zeru, bityo imipira ingana ya diameter ikoreshwa cyane mumiyoboro ya peteroli na gaze kuko byoroshye gusukura umuyoboro.Kuberako umupira wumupira wumupira wahanaguwe mugihe cyo gufungura no gufunga, imipira myinshi yumupira irashobora gukoreshwa mubitangazamakuru hamwe nibice bikomeye byahagaritswe.Ukurikije ibikoresho byimpeta ya kashe, irashobora kandi gukoreshwa mubifu namakuru ya granular.
6 Umupira wumupira wigihe
Kubera ko umupira wumupira usanzwe ukoresha reberi, nylon na polytetraoxyethylene nkibikoresho bifunga intebe, ubushyuhe bwabwo bukoreshwa bugarukira ku ntebe ya valve ifunga impeta.Ingaruka yo guca ubugari bwumupira igerwaho numupira wicyuma ukandamizwa hagati yintebe ya plastike ya plastike munsi yikintu giciriritse (umupira wamaguru ureremba).Mugihe cyibikorwa byumuvuduko runaka, intebe ya valve ifunga impeta ihindagurika kuburyo bworoshye kandi muburyo bwa plastike mubice bimwe.Ihindurwa rishobora kwishura ibyakozwe neza hamwe nubuso bwumupira, kandi bigakora imikorere yikimenyetso cyumupira.
Byongeye kandi, kubera ko impeta yo gufunga intebe yumupira wumupira mubusanzwe iba ikozwe muri plastiki, mugihe uhitamo imiterere nimikorere ya valve yumupira, birakenewe ko harebwa uburyo bwo kurwanya umuriro no kurwanya umuriro wumupira wumupira, cyane cyane muri peteroli, imiti, metallurgie nizindi nzego, mubitangazamakuru byaka kandi biturika Gukoresha imipira yumupira mubikoresho na sisitemu yo kuvoma muri Amerika bigomba kurushaho kwita ku kurwanya umuriro no gukumira umuriro.
Mubisanzwe, muguhindura imyanya ibiri, gukora cyane gufunga, icyondo, gukuramo, umuyoboro wijosi, gufungura byihuse no gufunga (1/4 gufungura no gufunga), guhagarika umuvuduko mwinshi (itandukaniro ryumuvuduko mwinshi), urusaku ruke, cavitation na guhumeka, Muri sisitemu yo kuvoma hamwe n’amazi make yamenetse mu kirere, urumuri ruto rukora hamwe n’amazi mato mato, birashoboka ko imipira yumupira.
Imipira yumupira nayo ikwiranye na sisitemu yo kuvoma ifite imiterere yumucyo, kugabanya umuvuduko muke (itandukaniro ryumuvuduko muto), nibitangazamakuru byangirika.
Imipira yumupira irashobora kandi gukoreshwa mubushyuhe buke (cryogenic) nibikoresho bya sisitemu.
Muri sisitemu ya ogisijeni yinganda zikora metallurgjiya, harasabwa imipira yumupira wakozwe nabi cyane.
Iyo imirongo nyamukuru iri mu miyoboro ya peteroli na gaze igomba gushyingurwa mu nsi, birasabwa imipira yuzuye ya diameter yuzuye.
Mugihe cyo guhindura imikorere bisabwa, umupira wumupira ufite imiterere yihariye ifungura V-shusho igomba guhitamo.
Muri peteroli, peteroli, imiti, amashanyarazi, n’ubwubatsi bwo mu mijyi, imipira y’icyuma ifunze imipira irashobora gukoreshwa muri sisitemu yo kuvoma ifite ubushyuhe bwo gukora hejuru ya 200 ° C.
7 Amahame yo gushyira mu bikorwa imipira yumupira
Ku miyoboro ya peteroli na gaze gasanzwe, imiyoboro igomba gusukurwa, igashyingurwa mu butaka, koresha inzira zose zambukiranya imipira yose;kubwo gushyingurwa mubutaka, hitamo pass-yose yasuditswe cyangwa imipira yumupira;imiyoboro yishami, Hitamo flange ihuza, gusudira, guhuza-byuzuye cyangwa kugabanya umupira wa diameter.
Kumiyoboro yo gutwara hamwe nibikoresho byo kubika amavuta meza, koresha imipira yumupira.
Kumurongo wa gazi numuyoboro wa gazi karemano, koresha imipira ireremba hamwe na flange ihuza hamwe nu murongo wimbere.
Muri sisitemu ya ogisijeni muri sisitemu ya metallurgiki, hagomba gukoreshwa valve yumupira uhamye wakorewe imiti igabanya ubukana kandi ihuza flang.
Kuri sisitemu yohasi yubushyuhe buke nibikoresho, hagomba gukoreshwa imipira yubushyuhe bwo hasi hamwe na bonnets.Muri sisitemu y'imiyoboro ya catalitike yamenetse yikigo gitunganya amavuta, hashobora gutorwa umupira wo mu bwoko bwa lift.
Mubikoresho no kuvoma imiyoboro yibitangazamakuru byangirika nka acide na alkali muri sisitemu yimiti, birasabwa gukoresha ibyuma byose byumupira wumupira wibyuma bikozwe mubyuma bya austenitike bidafite ibyuma na polytetraoxyethylene nkicyicaro nimpeta.
Ibyuma bifata ibyuma bifata ibyuma birashobora gukoreshwa muri sisitemu yo kuvoma cyangwa ibikoresho byitangazamakuru ryubushyuhe bwo hejuru muri sisitemu ya metallurgie, sisitemu y’amashanyarazi, ibikoresho bya peteroli, hamwe n’ubushyuhe bwo mu mujyi.
Iyo bisabwa guhinduranya ibintu, gutwara inyo-yinyo, pneumatike cyangwa amashanyarazi yumupira hamwe nifungura V-irashobora guhitamo.
