Irembo ry'Irembo: Irembo ry'irembo ni valve ikoresha irembo (isahani y'irembo) kugirango igende ihagaritse ku murongo w'igice. Ikoreshwa cyane cyane mumiyoboro yo gutandukanya uburyo, ni ukuvuga, gufungura byuzuye cyangwa gufunga byuzuye. Mubisanzwe, amarembo y amarembo ntabwo akwiriye kugenzurwa neza. Birashobora gukoreshwa kubushyuhe buke nubushyuhe bwo hejuru hamwe nigitutu cyogukoresha, bitewe nibikoresho bya valve.
Nyamara, amarembo y amarembo ntabwo akoreshwa mumiyoboro itwara ibicucu cyangwa ibitangazamakuru bisa.
Ibyiza:
Kurwanya amazi make.
Irasaba urumuri ruto rwo gufungura no gufunga.
Irashobora gukoreshwa muri sisitemu yuburyo bubiri, yemerera uburyo bwo gutembera mubyerekezo byombi.
Iyo ifunguye byuzuye, hejuru yikidodo ntigishobora kwibasirwa nisuri kuva mubikorwa bikora ugereranije numubumbe wisi.
Imiterere yoroshye hamwe nuburyo bwiza bwo gukora.
Uburebure bwimiterere.
Ibibi:
Ibipimo binini muri rusange hamwe n'umwanya wo kwishyiriraho urakenewe.
Ugereranije no guterana hejuru no kwambara hagati yikimenyetso mugihe cyo gufungura no gufunga, cyane cyane kubushyuhe bwinshi.
Irembo ry'irembo mubusanzwe rifite ubuso bubiri bwo gufunga, bushobora kongera ingorane mugutunganya, gusya, no kubungabunga.
Igihe kirekire cyo gufungura no gufunga.
Ibyiza:
Imiterere yoroshye, ingano yoroheje, yoroheje, hamwe no gukoresha ibikoresho bike, bigatuma ikwiranye na diameter nini.
Gufungura byihuse no gufunga hamwe no kurwanya umuvuduko muke.
Irashobora gukoresha itangazamakuru hamwe nuduce twinshi twahagaritswe kandi irashobora gukoreshwa mubutaka bwa poweri na granular media bitewe nimbaraga zubuso bwa kashe.
Birakwiriye gufungura ibyerekezo byombi, gufunga, no kugenzura imiyoboro ihumeka no gukuramo ivumbi. Ikoreshwa cyane muri metallurgie, inganda zoroheje, ingufu, na sisitemu ya peteroli ya miyoboro ya gazi n'inzira z'amazi.
Ibibi:
Urutonde ntarengwa rwo kugenzura imigezi; iyo valve ifunguye 30%, igipimo cyo gutemba kizarenga 95%.
Ntibikwiye kubushyuhe bwo hejuru nubushyuhe bwumuvuduko mwinshi bitewe nubushobozi bwimiterere nibikoresho bifunga. Mubisanzwe, ikora mubushyuhe buri munsi ya 300 ° C na PN40 cyangwa munsi.
Ugereranije imikorere idahwitse ugereranije numupira wumupira hamwe nisi yisi, kubwibyo ntabwo ari byiza kubisabwa bifite ibyangombwa byinshi byo gufunga.
Umupira wumupira: Umupira wumupira ukomoka kumacomeka, kandi ikintu cyo gufunga ni umuzenguruko uzenguruka dogere 90 uzengurutse umurongo waindangastem kugirango ugere ku gufungura no gufunga. Umupira wumupira ukoreshwa cyane cyane mumiyoboro yo gufunga, gukwirakwiza, no guhindura icyerekezo. Imipira yumupira hamwe na V ifungura nayo ifite ubushobozi bwiza bwo kugenzura ibintu.
Ibyiza:
Kurwanya umuvuduko muke (hafi zeru).
Porogaramu yizewe mubitangazamakuru byangirika hamwe n'amazi make yo guteka kuko adafatana mugihe cyo gukora (nta mavuta).
Kugera kashe yuzuye muburyo butandukanye bwumuvuduko nubushyuhe.
Gufungura byihuse no gufunga, hamwe nuburyo bumwe bufite igihe cyo gufungura / gufunga igihe gito nkamasegonda 0.05 kugeza 0.1, bikwiranye na sisitemu yo kwikora mukugerageza intebe nta ngaruka mugihe gikora.
Guhagarara byikora kumupaka hamwe nibintu byo gufunga umupira.
Ikidodo cyizewe kumpande zombi zikoreshwa.
Nta isuri yo gufunga hejuru yibitangazamakuru byihuta iyo ifunguye cyangwa ifunze.
Imiterere yoroheje kandi yoroheje, ikabigira imiterere ya valve ikwiranye na sisitemu yubushyuhe buke.
Umubiri wa simmetrike, cyane cyane mumibiri yumubiri wasizwe, urashobora kwihanganira imihangayiko ituruka kumiyoboro.
Ikintu cyo gufunga kirashobora kwihanganira itandukaniro ryumuvuduko mwinshi mugihe cyo gufunga. Umuyoboro wuzuye wumupira wuzuye ushobora gushyingurwa mubutaka, ukareba ko ibice byimbere bitangirika, hamwe nigihe kinini cyakazi cyimyaka 30, bigatuma biba byiza mumiyoboro ya peteroli na gaze.
Ibibi:
Ibikoresho nyamukuru bifunga impeta yumupira ni polytetrafluoroethylene (PTFE), yinjizwamo imiti hafi ya yose kandi ifite ibimenyetso byuzuye nka coefficient de fraisement nkeya, imikorere ihamye, kurwanya gusaza, ubushyuhe bwagutse bukwiranye, hamwe nuburyo bwiza bwo gufunga.
Nyamara, imiterere yumubiri ya PTFE, harimo coefficente yo kwaguka kwinshi, kumva neza ubukonje, hamwe nubushyuhe buke bwumuriro, bisaba gushushanya kashe yintebe kugirango ishingiye kubyo biranga. Kubwibyo, iyo ibikoresho byo gufunga bigoye, ubwizerwe bwa kashe burahungabana.
Byongeye kandi, PTFE ifite igipimo cyo kurwanya ubushyuhe buke kandi irashobora gukoreshwa munsi ya 180 ° C. Kurenga ubu bushyuhe, ibikoresho bifunga bizasaza. Urebye imikoreshereze y'igihe kirekire, muri rusange ntabwo ikoreshwa hejuru ya 120 ° C.
Imikorere yacyo igenzura irarenze iy'umubumbe w'isi, cyane cyane pneumatike (cyangwa amashanyarazi).
Globe Valve: Yerekeza kuri valve aho ikintu cyo gufunga (disiki ya valve) kigenda kumurongo wo hagati wintebe. Guhindagurika kwicyicaro cyicyicaro biragereranijwe neza nurugendo rwa disiki ya valve. Bitewe nurugendo rugufi rwo gufungura no gufunga ubu bwoko bwa valve nibikorwa byizewe byo kuzimya, kimwe nubusabane bugereranijwe hagati yo gutandukana kwicyicaro cyurugendo ningendo za disiki ya valve, birakwiriye cyane kugenzurwa neza. Kubwibyo, ubu bwoko bwa valve busanzwe bukoreshwa muguhagarika, kugenzura, no gutera akabariro.
Ibyiza:
Mugihe cyo gufungura no gufunga, imbaraga zo guterana hagati ya disiki ya valve nubuso bwo gufunga umubiri wa valve ni ntoya kuruta iy'irembo, bigatuma irwanya kwambara.
Uburebure bwo gufungura muri rusange ni 1/4 cyumuyoboro wintebe, bigatuma biba bito cyane kuruta irembo.
Mubisanzwe, hari ubuso bumwe gusa bwo gufunga kumubiri wa valve na disiki ya valve, byoroshye gukora no gusana.
Ifite ubushyuhe bwo hejuru bwo guhangana nubushyuhe kuko gupakira mubisanzwe ni uruvange rwa asibesitosi na grafite. Umubumbe wisi ukunze gukoreshwa kumashanyarazi.
Ibibi:
Bitewe nimpinduka mubyerekezo bitemba byanyuze hagati ya valve, byibuze kugabanuka kwimyuka yisi ya globe irarenze iyindi moko menshi ya valve.
Kubera inkoni ndende, umuvuduko wo gufungura uratinda ugereranije numupira wumupira.
Gucomeka Valve: Yerekeza kuri valve izenguruka hamwe nikintu cyo gufunga muburyo bwa silinderi cyangwa icyuma cya cone. Umuyoboro wacometse kumurongo wacometse kuri dogere 90 kugirango uhuze cyangwa utandukane igice cyumubiri wa valve, kugera kumugaragaro cyangwa gufunga valve. Imiterere ya plaque ya valve irashobora kuba silindrike cyangwa conical. Ihame ryarwo risa n'iry'umupira w'amaguru, wakozwe hashingiwe ku cyuma gicomeka kandi gikoreshwa cyane cyane mu gucukura peteroli kimwe n'inganda za peteroli.
Agaciro k'umutekano: Ikora nk'igikoresho cyo gukingira bikabije ku bwato, ibikoresho, cyangwa imiyoboro. Iyo umuvuduko uri mubikoresho, ubwato, cyangwa umuyoboro urenze agaciro kemewe, valve ihita ifungura kugirango irekure ubushobozi bwuzuye, irinde kongera umuvuduko. Iyo igitutu kigabanutse ku giciro cyagenwe, valve igomba guhita ifunga bidatinze kugirango ikingire umutekano wibikoresho, ubwato, cyangwa umuyoboro.
Umutego wamazi: Mugutwara umwuka, umwuka ucanye, nibindi bitangazamakuru, hakorwa amazi ya kondensate. Kugirango hamenyekane imikorere nigikorwa cyizewe cyigikoresho, birakenewe gusohora mugihe gikwiye ibyo bitangazamakuru bidafite akamaro kandi byangiza kugirango ukomeze gukoresha no gukoresha igikoresho. Ifite imirimo ikurikira: (1) Irashobora gusohora vuba amazi ya kondensate yatanzwe. (2) Irinda kumeneka. (3) Ikuraho.
Kugabanya Umuvuduko Wumuvuduko: Numuyoboro ugabanya umuvuduko winjira kumuvuduko wifuzwa usohoka binyuze muguhindura kandi wishingikiriza kumyuka yikigereranyo ubwacyo kugirango uhite ugumana umuvuduko uhamye wo gusohoka.
Reba Valve: Bizwi kandi nka valve idasubira inyuma, ikumira inyuma, umuvuduko winyuma, cyangwa inzira imwe. Iyi mibande ihita ifungurwa kandi igafungwa nimbaraga zatewe no gutembera kwinzira mu muyoboro, bigatuma iba ubwoko bwa valve yikora. Kugenzura indangagaciro zikoreshwa muri sisitemu y'imiyoboro kandi imirimo yabo nyamukuru ni ukurinda gusubira inyuma hagati, gukumira ihinduka rya pompe na moteri yo gutwara, no kurekura itangazamakuru rya kontineri. Kugenzura indangagaciro zirashobora kandi gukoreshwa kumiyoboro itanga sisitemu yubufasha aho umuvuduko ushobora kuzamuka hejuru yumuvuduko wa sisitemu. Bashobora gushyirwa mubyiciro byubwoko (kuzunguruka bishingiye hagati ya rukuruzi) hamwe no kuzamura ubwoko (bugenda buva kumurongo).
