Wige ubwoko butandukanye bwa valve ikoreshwa mubikorwa bya peteroli na gaze nibitandukaniro: Irembo rya API na ASME, isi, kugenzura, umupira, n'ibishushanyo by'ibinyugunyugu (intoki cyangwa ikora, hamwe n'imibiri yahimbwe kandi ikozwe). Muri make, valves ni ibikoresho byubukanishi bikoreshwa mugukoresha imiyoboro yo kugenzura, kugenzura no gufungura / gufunga umuvuduko wamazi nigitutu. Ibyuma byahimbwe bikoreshwa kuri bore ntoya cyangwa umuvuduko ukabije wogukoresha imiyoboro, guteramo ibyuma byo kuvoma hejuru ya santimetero 2.
AGACIRO NIKI?
Ubwoko butandukanye bwa valves zikoreshwa munganda za peteroli zikwiranye nimwe muribi bikurikira:
1. Tangira / uhagarike urujya n'uruza rw'amazi (hydrocarbone, amavuta na gaze, amavuta, amazi, acide) unyuze mu muyoboro (urugero: valve y'irembo, umupira w'amaguru, umupira w'ikinyugunyugu, icyuma cy'irembo, cyangwa icyuma gipima)
2. Hindura urujya n'uruza rw'amazi unyuze mu muyoboro (urugero: globe valve)
3. Kugenzura urujya n'uruza rw'amazi (kugenzura valve)
4. Hindura icyerekezo cyurugendo (urugero: inzira-3 yumupira wumupira)
5. Tunganya igitutu cyibikorwa (igitutu kigabanya valve)
6. Kurinda sisitemu yo kuvoma cyangwa igikoresho (pompe, moteri, tank) kwirinda gukabya (umutekano cyangwa kugabanya umuvuduko) cyangwa igitutu cyinyuma (cheque valve)
7. Shungura imyanda inyura mu muyoboro, kugirango urinde ibikoresho bishobora kwangizwa nibice bikomeye (y hamwe nuduseke)
Umuyoboro ukorwa muguteranya ibice byinshi byubukanishi, ibyingenzi ni umubiri (igikonoshwa cyo hanze), trim (guhuza ibice byasimbuwe bisimbuwe), uruti, bonnet, hamwe nuburyo bukoreshwa (lever manual, gear or Umukoresha).
Imyanda ifite ubunini buke (muri rusange santimetero 2) cyangwa bisaba guhangana cyane nigitutu nubushyuhe bikozwe hamwe nibyuma byahimbwe; ububiko bwubucuruzi hejuru ya santimetero 2 muri diameter biranga ibikoresho byumubiri.
AGACIRO KUBYEREKEYE
● GATE VALVE: Ubu bwoko nuburyo bukoreshwa cyane mugukoresha imiyoboro. Irembo ry'irembo ni ibikoresho bigenda byifashishwa bifunguye kandi bifunga urujya n'uruza rw'amazi (shutoff valve). Irembo ry'irembo ntirishobora gukoreshwa mugukoresha porogaramu, ni ukuvuga kugenzura imigendekere y'amazi (isi cyangwa imipira igomba gukoreshwa muriki gihe). Irembo ry'irembo rero, ryarafunguwe cyangwa rifunze (ukoresheje ibiziga by'intoki, ibyuma cyangwa amashanyarazi, pneumatike na hydraulic actuator)
V AGACIRO KA GLOBE: Ubu bwoko bwa valve bukoreshwa mugutembera (kugenzura) amazi. Umubumbe wisi urashobora kandi guhagarika urujya n'uruza, ariko kubwiyi mikorere, amarembo y amarembo arahitamo. Umuyoboro w'isi utera umuvuduko ukabije mu muyoboro, kuko amazi agomba kunyura mu nzira itari umurongo.
SHAKA AGACIRO: ubu bwoko bwa valve bukoreshwa kugirango wirinde gusubira inyuma muri sisitemu yo kuvoma cyangwa umuyoboro ushobora kwangiza ibikoresho byo hepfo nka pompe, compressor, nibindi. Iyo amazi afite umuvuduko uhagije, ifungura valve; iyo igarutse (revers flow) kumuvuduko wigishushanyo, ifunga valve - ikumira imigendere idashaka.
● UMUPIRA W'UMUPIRA: Umupira wumupira ni kimwe cya kane gihinduranya ikoreshwa muguhagarika porogaramu. Umuyoboro urakingura kandi ugafunga umuvuduko wamazi ukoresheje umupira wubatswe, uzunguruka imbere mumubiri wa valve. Imipira yumupira ninganda zisanzwe kuri porogaramu kandi ziroroshye kandi zoroshye kuruta amarembo y amarembo, akora intego zisa. Ibishushanyo bibiri byingenzi bireremba na trunnion (kuruhande cyangwa hejuru yinjira)
AG AGACIRO KA BUTTERFLY: Iyi ni ibintu byinshi, bikoresha amafaranga menshi, valve yo guhindura cyangwa gufungura / gufunga imigezi y'amazi. Ibinyugunyugu biraboneka mubishushanyo mbonera cyangwa inshuro ebyiri (kabiri / gatatu), bifite imiterere ihuriweho kandi bigenda birushaho guhatanwa nu mipira yumupira, bitewe nubwubatsi bworoshye nigiciro.
● PINCH VALVE: Ubu ni ubwoko bwumurongo wumurongo wumurongo ushobora gukoreshwa mugutereta no gufunga porogaramu mugukoresha imiyoboro ikora ibikoresho bikomeye, ibishishwa hamwe namazi yuzuye. Umuyoboro wa pinch urimo umuyoboro muto kugirango ugenzure imigendere.
● GUKORA AGACIRO: Gucomeka valve yashyizwe mubikorwa nka kimwe cya kane cyo guhinduranya valve kugirango uhagarike porogaramu. Umuyoboro wa mbere wacometse ku Baroma kugira ngo bagenzure imiyoboro y'amazi.
AG AGACIRO K'UMUTEKANO: Umuyoboro w’umutekano ukoreshwa mu kurinda imiyoboro ituruka ku muvuduko ukabije ushobora guhungabanya ubuzima bw’abantu cyangwa undi mutungo. Byibanze, valve yumutekano irekura igitutu nkuko igiciro-kirenze.
● KUGENZURA AGACIRO: izi ni indangagaciro zo gutangiza inzira ya peteroli.
● Y-ABAYOBOZI: mugihe bidakwiye neza valve, Y-strain ifite umurimo wingenzi wo kuyungurura imyanda no kurinda ibikoresho byo hasi bishobora kwangirika ukundi
