1. UMUKINO W'UMUPIRA WIZA X9002 ugomba kubikwa mucyumba cyumye kandi gihumeka, kandi impande zombi zigomba guhagarikwa.
2. Imyanda ibitswe igihe kirekire igomba kugenzurwa buri gihe kugirango ikureho umwanda kandi ushyireho amavuta arwanya ingese hejuru yo gutunganya.
3. Nyuma yo kwishyiriraho, hagomba gukorwa ubugenzuzi busanzwe, ibintu byingenzi byubugenzuzi:
(1) Kwambara imiterere yo gufunga hejuru.
(2) Kwambara insinga za trapezoidal ya valve stem na nut stem stem.
(3) Niba gupakira bitajyanye n'igihe kandi bitemewe, niba byangiritse, bigomba gusimburwa mugihe.
(4) Nyuma ya valve imaze kuvugururwa no guterana, hagomba gukorwa ikizamini cyo gukora kashe.
Igikorwa cyo gufata neza mugihe cyo gutera inshinge
Kubungabunga valve mbere na nyuma yo gusudira bigira uruhare runini mubikorwa no gukora bya valve.Gukosora neza, gutondeka kandi neza bizarinda valve, gukora imikorere ya valve mubisanzwe kandi byongere ikoreshwa rya valve.ubuzima.Kubungabunga Valve birasa nkibyoroshye, ariko sibyo.Hariho ibintu byinshi byirengagizwa.
1. Iyo valve irimo gutera amavuta, ikibazo cyinshinge zamavuta gikunze kwirengagizwa.Nyuma yimbunda yamavuta, uyikoresha ahitamo valve nuburyo bwo guhuza amavuta, hanyuma akora igikorwa cyo gutera amavuta.Hariho ibintu bibiri: kuruhande rumwe, ingano yo guteramo amavuta ni nto, kandi inshinge zamavuta ntizihagije, kandi hejuru yikimenyetso cyambara vuba kubera kubura amavuta.Kurundi ruhande, inshinge nyinshi zitera imyanda.Impamvu nuko nta kubara kubushobozi butandukanye bwo gufunga ububiko ukurikije icyiciro cyubwoko bwa valve.Ubushobozi bwo gufunga bushobora kubarwa hashingiwe ku bunini bwa valve n'ubwoko, hanyuma hashobora guterwa amavuta yuzuye.
2. Iyo valve isizwe amavuta, ikibazo cyumuvuduko gikunze kwirengagizwa.Mugihe cyo gutera ibinure, igitutu cyo gutera amavuta gihinduka buri gihe mumisozi no mubibaya.Niba igitutu ari gito cyane, kashe iratemba cyangwa ikananirwa, igitutu ni kinini, icyambu cyo guteramo amavuta kirahagarikwa, amavuta yo muri kashe arakomera, cyangwa impeta yo gufunga ifunze umupira wa valve na plaque.Mubisanzwe, iyo igitutu cyo gutera amavuta ari gito cyane, amavuta yatewe ahanini atembera munsi yumwobo wa valve, ubusanzwe aboneka mumarembo mato.Niba igitutu cyo gutera amavuta ari kinini cyane, kuruhande rumwe, reba nozzle yatewe amavuta, niba umwobo wamavuta uhagaritswe, usimbuze;kurundi ruhande, niba amavuta akomeye, koresha amazi yoza kugirango woroshye inshuro nyinshi amavuta yananiwe gufunga hanyuma utere amavuta mashya kugirango uyasimbuze..Byongeye kandi, ubwoko bwa kashe hamwe nibikoresho byo gufunga nabyo bigira ingaruka kumuvuduko wamavuta.Impapuro zitandukanye zifunga zifite imbaraga zo gutera amavuta.Mubisanzwe, igitutu cyo gutera amavuta kubidodo bikomeye bigomba kuba ikimenyetso cyoroshye.
3. Iyo valve isizwe amavuta, witondere ikibazo cya valve mumwanya uhindura.Umupira wumupira mubusanzwe uri mumwanya ufunguye mugihe cyo kubungabunga.Mubihe bidasanzwe, byatoranijwe gufungwa kugirango bibungabunge.Indi mibande ntishobora gufatwa nkimyanya ifunguye.Irembo ry irembo rigomba gufungwa mugihe cyo kubungabunga kugirango amavuta yuzuze igikonjo gifunga impeta.Niba ifunguye, amavuta yo gufunga azahita agwa mumuyoboro utemba cyangwa mumyanda ya valve, bigatera imyanda.
4. Iyo valve isizwe amavuta, ikibazo cyingaruka zo gutera amavuta akenshi cyirengagizwa.Mugihe cyo gutera amavuta, igitutu, ingano yo gutera amavuta, hamwe nu mwanya wo guhinduranya byose nibisanzwe.Ariko rero, kugirango tumenye neza ingaruka zo gutera amavuta ya valve, rimwe na rimwe biba ngombwa gukingura cyangwa gufunga valve kugirango ugenzure ingaruka zamavuta kugirango hemezwe ko ubuso bwumupira cyangwa irembo bisizwe neza.
5. Mugihe utera amavuta, witondere ikibazo cyamazi yumubiri wa valve no kugabanya ingufu zumuvuduko.Nyuma yikizamini cyumuvuduko wa valve, gaze nubushuhe mumyanya ya valve ya cavite ifunze biziyongera kumuvuduko kubera kwiyongera kwubushyuhe bwibidukikije.Iyo hashyizwemo amavuta, umwanda nigitutu bigomba gusohoka kugirango byoroherezwe gutera inshinge.Amavuta amaze guterwa, umwuka nubushuhe mumyanya ifunze birasimburwa byuzuye.Kuraho umuvuduko wa valve cavite mugihe, nacyo cyemeza umutekano wa valve.Nyuma yo guterwa amavuta, menya neza ko wogosha imiyoboro y'amazi hamwe nigitutu cyo kugabanya impanuka kugirango wirinde impanuka.
6. Mugihe utera amavuta, witondere ikibazo cyamavuta asohoka.Mugihe cyo gutera inshinge zisanzwe, isohoka ryamavuta yegereye icyambu cyo guteramo amavuta izasohoka mbere, hanyuma igere kumwanya muto, hanyuma igere kumurongo muremure nyuma yanyuma, hanyuma isohore amavuta bikurikiranye.Niba idakurikije amategeko cyangwa idatanga ibinure, irerekana ko hariho inzitizi, kandi ikabikuraho mugihe.
7. Mugihe utera amavuta, reba kandi ikibazo cyo gutemba cya diameter ya valve hamwe nintebe yimpeta.Kurugero, kumipira yumupira, niba hari umwanya ufunguye wivanze, imipaka ifunguye irashobora guhinduka imbere kugirango hemezwe ko diameter igororotse kandi ifunze.Guhindura imipaka ntarengwa, ntugomba gukurikirana gusa gufungura cyangwa gufunga, ahubwo ugomba gutekereza kumwanya rusange.Niba imyanya yo gufungura ari flush kandi umwanya wo gufunga ntabwo uri mukibanza, valve ntizafunga cyane.Muri ubwo buryo bumwe, niba ihinduka rihari, ihinduka rihuye ryimyanya ifunguye naryo rigomba gusuzumwa.Menya neza ingendo zingendo za valve.
8. Nyuma yo gutera amavuta, icyambu cyo gutera amavuta kigomba gufungwa.Irinde kwinjiza umwanda cyangwa okiside ya lipide ku cyambu cyo gutera amavuta.Amavuta yo kurwanya ingese agomba gukoreshwa ku gipfukisho kugirango wirinde ingese.Kugirango ishobore gukoreshwa mubikorwa bitaha.
9. Icyenda, mugihe utera amavuta, birakenewe kandi gutekereza kubuvuzi bwihariye bwibibazo byihariye mugutwara ibicuruzwa bikomoka kuri peteroli mugihe kizaza.Urebye imico itandukanye ya mazutu na lisansi, hagomba gutekerezwa ubushobozi bwa lisansi no kubora.Mubikorwa bizaza bya valve, mugihe uhuye nibikorwa bya lisansi, wuzuze amavuta mugihe kugirango wirinde kwambara.
10. Mugihe utera amavuta, ntukirengagize inshinge zamavuta kuruti rwa valve.Hano hari akaboko kanyerera cyangwa gupakira kuri shitingi ya valve, nayo igomba guhora isizwe kugirango igabanye ubukana bwo guterana amagambo mugihe ikora.Niba amavuta adashobora kwizerwa, urumuri ruziyongera mugihe cyo gukora amashanyarazi kandi ibice byo kwambara bizakorwa mugihe cyo gukora intoki.
11. Imipira imwe yumupira irangwa nimyambi kumubiri wa valve.Niba nta cyongereza FIOW cyanditse, ni icyerekezo cyibikorwa byintebe ya kashe, idakoreshwa nkurwego rwo gutembera kwicyerekezo cyo hagati, kandi icyerekezo cya valve cyo kwisohora kinyuranye.Mubisanzwe, imyanya ibiri ifunze umupira wa valve ifite icyerekezo cyerekezo cyerekezo.
12. Mugihe ukomeza valve, witondere kwinjiza amazi mumutwe wamashanyarazi nuburyo bwo kohereza.Cyane cyane imvura yinjira mugihe cyimvura.Imwe muriyo ni ugusenya uburyo bwo kohereza cyangwa amaboko yohereza, naho ubundi ni ugukonja mu gihe cy'itumba.Tera itara rinini cyane mugihe amashanyarazi akoreshwa, kandi kwangiriza ibice byogukwirakwiza bizatera moteri gupakururwa cyangwa kurinda * torque gukandagira kandi ibikorwa byamashanyarazi ntibishobora kugerwaho.Ibice byoherejwe byangiritse, kandi ibikorwa byintoki ntibishobora gukorwa.Nyuma yo kurinda * torque ikora, ibikorwa byintoki nabyo ntibishobora guhinduka.Gukora ku gahato byangiza ibice byimbere.
