Bikwiranye no gushirahoirembo, globe, umupira wamaguru, ikinyugunyugun'umuvuduko ugabanya valve mubikoresho bya peteroli.Reba valve, umutekano wumutekano, kugenzura valve, umutego washyizeho reba amabwiriza abigenga.Ntibikwiriye gushyirwaho indiba kumazi yo munsi y'ubutaka hamwe n'imiyoboro y'amazi.
1. Kwemeza amahame yimiterere
1.1 Indangagaciro zigomba gushyirwaho ukurikije ubwoko nubunini bwerekanwe mu mbonerahamwe ya PID yerekana imiyoboro n'ibikoresho.Iyo PID ifite ibisabwa byihariye byo kwishyiriraho imyanya imwe nimwe, igomba gushyirwaho ukurikije ibisabwa.
1.2 Indangagaciro zigomba gutondekwa ahantu byoroshye kuhagera, byoroshye gukora kandi byoroshye kubungabunga.Imyanya kumurongo wimiyoboro igomba gutondekwa hagati, hamwe nibikorwa byo gukora cyangwa urwego.
2. Kwemeza ibyangombwa bisabwa
2.1 Imyanda yaciwe igomba gushyirwaho mugihe imiyoboro yerekana imiyoboro yibikoresho byinjira n’ibisohoka ihujwe na shebuja wububiko bwuruganda rwose.Umwanya wo kwishyiriraho wa valve ugomba gutondekwa hagati kuruhande rumwe rwibikoresho, kandi urubuga rukenewe cyangwa urubuga rwo kubungabunga rugomba gushyirwaho.
2.2 Indangagaciro zisaba gukora kenshi, kubungabunga no gusimbuza bigomba kuba ahantu hashobora kugera kubutaka, urubuga cyangwa urwego.Indwara ya pneumatike n amashanyarazi nayo igomba gutondekwa ahantu byoroshye kuboneka.
2.3 Indangagaciro zidakeneye gukoreshwa kenshi (gusa gufungura no guhagarara) nazo zigomba gushyirwa ahantu hashobora gushyirwaho urwego rwigihe gito niba rudashobora gukorerwa hasi.
2.4 Hagati yintoki ya valve igomba kuba 750 ~ 1500mm uvuye hejuru yimikorere, kandi uburebure bukwiye ni 1200mm.Uburebure bwubushakashatsi bwa valve budakeneye gukora kenshi burashobora kugera kuri 1500 ~ 1800mm.Mugihe uburebure bwo kwishyiriraho budashobora kugabanuka kandi birakenewe kenshi, urubuga rukora cyangwa gukandagira bigomba gushyirwaho mubishushanyo.Imyanda iri mu miyoboro n'ibikoresho bifite itangazamakuru rishobora guteza akaga ntibishobora gushyirwa mu burebure bw'umutwe w'umuntu.
2.5 Iyo hagati yintoki ya valve irenze 1800mm kuva murwego rwo hejuru yubuso bukora, birakwiye gushiraho ibikorwa bya spock.Urunigi rw'isoko rugomba kuba hafi 800mm uvuye hasi, kandi urunigi rw'urunigi rugomba gushyirwaho kugirango umanike impera yo hepfo y'urunigi ku rukuta cyangwa hafi yacyo, kugira ngo bitagira ingaruka ku gice
2Niba ari munsi ya 300mm, umugozi wagutse wa valve ugomba gushyirwaho kugirango intoki zintoki ziri munsi ya 100mm munsi yumupfundikizo.
2.7. no kurambura inkoni y'intoki intera ikora hejuru ya 1200mm irakwiriye.Imyanya ifite diameter nominal ya DN40 cyangwa munsi yayo kandi ihujwe nu murongo ntigomba gukoreshwa hamwe na spockets cyangwa inkoni yagutse kugirango birinde kwangirika.Muri rusange, indangagaciro zigomba gukoreshwa hamwe nisoko ntoya cyangwa kwagura inkoni ishoboka.
2.8 Intera iri hagati yuruziga rwamaboko ya valve itondekanye kuri platifomu nu nkombe ya platifomu ntigomba kurenza mm 450.Iyo igiti cya valve na handwheel bigeze hejuru ya platifomu kandi uburebure buri munsi ya mm 2000, ntibigomba kugira ingaruka kumikorere no kunyura k'umukoresha, kugirango bidatera igikomere ku giti cye.
3. Ibisabwa binini byo gushiraho
3.1 Imikorere ya valve nini igomba gukoresha uburyo bwo kohereza ibikoresho, kandi umwanya wumwanya usabwa nuburyo bwo kohereza ugomba kwitabwaho mugihe washyizeho.
3.2 Inkunga igomba gushyirwaho kuruhande rumwe cyangwa impande zombi za valve kumpande nini.Inkunga ntigomba kuba iri kumuyoboro mugufi ugomba gukurwaho mugihe cyo kuyitunganya, kandi inkunga yumuyoboro ntigomba kugira ingaruka mugihe cyo gukuraho valve.Mubisanzwe, intera iri hagati yinkunga na valve flange igomba kuba irenga 300mm.
3.3 Umwanya wo kwishyiriraho ibinini binini ugomba kugira urubuga rwo gukoresha crane, cyangwa ugatekereza gushiraho davit no kumanika ibiti.
4. Ibisabwa kuri valve kumiyoboro itambitse
4.1 Usibye ibisabwa byihariye byuburyo bukoreshwa, intoki za valve zashyizwe kumuyoboro rusange utambitse ntizishobora kumanuka, cyane cyane valve kumuyoboro uteye akaga birabujijwe rwose.Icyerekezo cyamaboko ya valve igenwa muburyo bukurikira: Uhagaritse hejuru; 和 orizontal; uhagaritse hejuru ibumoso n'iburyo uhengamye 45 °; uhagaritse hepfo ibumoso n'iburyo uhengamye 45 °; ntabwo uhagaze hepfo.

5. Ibindi bisabwa mugushiraho valve
5.1 Umurongo wo hagati wa valve kumiyoboro ibangikanye ugomba kuba mwiza bishoboka.Iyo valve itunganijwe kuruhande, intera igaragara hagati yintoki ntizigomba kuba munsi ya 100mm;Imyanya irashobora kandi gutondekwa kugirango igabanye intera.
5Iyo valve ari flange ya flake, birakenewe kubaza ibikoresho byumwuga gushiraho flave ya convex kuri nozzle ihuye.
5.3 Keretse niba inzira ifite ibisabwa byihariye, indiba ziri kumuyoboro wo hasi wiminara, reakteri, imiyoboro ihagaritse nibindi bikoresho ntibishobora gutondekwa mumajipo.
5.4.
5.5 Umuyoboro wamashami waciwe na valve kumurongo wububiko ntukorwa kenshi (gusa guhagarika no kubungabunga).Niba nta ngazi ihoraho, umwanya ugomba gushyirwa kuruhande kugirango ukoreshe urwego rwigihe gito.
5.6 Iyo hafunguwe umuvuduko mwinshi wumuvuduko, imbaraga zo gutangira nini, kandi inkunga igomba gushyirwaho kugirango ishyigikire valve kandi igabanye imihangayiko yo gutangira.Uburebure bwo kwishyiriraho bugomba kuba 500 ~ 1200mm.
5.7 Umuyoboro wamazi yumuriro hamwe numuriro wumuriro wumupaka wibikoresho bigomba kugabanwa ahantu hizewe uwabikoresheje byoroshye kubigeraho mugihe habaye impanuka.
5.8 Itsinda rya valve ryumuriro uzimya umuyoboro wo gukwirakwiza amashyiga yo gushyushya bigomba kuba byoroshye gukora, kandi intera iri hagati yimiyoboro ikwirakwizwa numubiri witanura ntigomba kuba munsi ya 7.5m.
5.9 Mugihe ushyira valve ifite umurongo uhujwe nu muyoboro, hagomba gushyirwaho ingingo nzima hafi ya valve kugirango isenywe.
5.10 Umuyoboro wa clamp cyangwaikinyugunyuguNtishobora guhuzwa neza na flanges yizindi valve na fitingi, kandi umuyoboro mugufi ufite flanges kumpande zombi ugomba kongerwaho hagati.
5.11 Umuyoboro ntugomba kwikorera umutwaro wo hanze, kugirango utangiza kwangirika kubera guhangayika cyane.
