Ibyuma by'icyuma gikozwe mu bushyuhe bwinshi n'umuvuduko mwinshi w'amashanyarazi make n'uruvange rw'umupira rushyirwa mu bushinwa.
Valve y'umupira w'icyuma cyakozwe mu buryo bwa Forged Steel Trunnion ni iki?
A Valve y'umupira w'icyuma gikozwe mu byumabivuze ko umupira ugorwa n'imigozi kandi wemerewe kuzenguruka gusa, igice kinini cy'umutwaro wa hydraulic gishyigikiwe n'imigozi ya Sisitemu, bigatuma umuvuduko wo gutwara ibintu ugabanuka kandi nta munaniro wo ku mugozi uharangwa.
Umuvuduko w'umuyoboro uyobora intebe yo hejuru ku mupira uhagaze ku buryo umuvuduko w'umuyoboro ushyira intebe yo hejuru ku mupira bigatuma ufunga. Gufata umupira mu buryo bwa mekanike bikuramo umuvuduko uva ku mupira, bikarinda gukururana gukabije hagati y'umupira n'intebe, bityo nubwo waba ufite umuvuduko wuzuye wo gukora ugakomeza kuba muto. Ibi ni byiza cyane iyo valve y'umupira ikoreshejwe kuko igabanya ingano y'icyuma gikoresha ingufu bityo bigatuma ikiguzi rusange cya valve ikoreshwa. Ingufu ziboneka ku bunini bwose no ku bwoko bwose bw'umuvuduko ariko ahanini ni iz'ingano nini n'imiterere y'umuvuduko mwinshi.
Ibiranga by'ingenzi bya NORTECH Forged steel trunnion ball valve
1. Guhagarika kabiri no kuva amaraso (DBB)
Iyo valve ifunze kandi umwobo wo hagati ugasukwa binyuze muri valve isohora amazi, intebe zo hejuru n'izo hasi zizafunga ku buryo bwihariye. Indi nshingano y'igikoresho gisohora amazi ni uko intebe ya valve ishobora kugenzurwa niba hari aho amazi yavuye mu gihe cy'igeragezwa. Byongeye kandi, imyanda iri mu mubiri ishobora kozwa binyuze mu gikoresho gisohora amazi. Igikoresho gisohora amazi cyagenewe kugabanya kwangirika kw'intebe bitewe n'imyanda iri mu gikoresho.
2. Torque nke ikora
Valve y'umupira w'umuyoboro wa trunnion ikoresha imiterere y'umupira w'urutare n'intebe y'urutare irembera, kugira ngo igabanuke imbaraga zayo mu gihe cy'umuvuduko wo gukora. Ikoresha PTFE yisiga n'icyuma gitemba kugira ngo igabanye ingano y'umuvuduko wo kugabanuka ku rugero rwo hasi hamwe n'ubukana bwinshi n'umubyimba mwinshi.
11. Igiti gikingira gutwika
Uruti rufata imiterere idapfa gucika. Uruti rwakozwe rufite ikirenge hasi ku buryo hamwe n'aho hejuru hashyizwe igipfundikizo n'urushundura, uruti rutazavamo n'icyuma nubwo haba hari izamuka ridasanzwe ry'umuvuduko mu mwobo w'urushundura.
Igiti kidapfa gutwikwa n'umuriro
4. Igishushanyo mbonera cy'imiterere idakongerwa n'umuriro
Mu gihe habayeho inkongi mu gihe cyo gukoresha valve, impeta y'intebe, impeta ya O n'impeta yo hagati ya O ikozwe muri PTFE, imipira y'ibindi bikoresho bitari icyuma bizabora cyangwa byangirike bitewe n'ubushyuhe bwinshi. Mu gihe cy'igitutu cy'icyuma, valve y'umupira izasunika icyuma gifata intebe vuba kijya ku mupira kugira ngo impeta y'icyuma ifatanye n'umupira maze ikore imiterere y'icyuma cyo gufunga icyuma, ishobora kugenzura neza amazi ya valve. Imiterere y'imiterere idasha umuriro ya valve y'umupira w'imiyoboro ya trunnion ihuye n'ibisabwa muri API 607, API 6FA, BS 6755 n'andi mabwiriza.
5. Imiterere irwanya imihindagurikire
Valve y'umupira yakozwe ifite imiterere irwanya static kandi ikoresha igikoresho gisohora amashanyarazi adahindagurika kugira ngo kibe umuyoboro uhoraho hagati y'umupira n'umubiri unyuze mu gice cy'imbere, kugira ngo gisohore amashanyarazi adahindagurika aturuka ku gukururana mu gihe cyo gufungura no gufunga umupira n'intebe binyuze mu muyoboro, birinda inkongi y'umuriro ishobora guterwa n'umuriro udahindagurika kandi bikizeza umutekano wa sisitemu.
6.Inyubako yizewe yo gufunga intebe
Gufunga intebe bikorwa binyuze mu bikoresho bibiri birekura intebe, bishobora kureremba mu buryo bw'uruhande kugira ngo bizibe amazi, harimo no gufunga umupira no gufunga umubiri. Gufunga intebe ya valve ku muvuduko muke bigaragazwa no gufunga umupira mbere yo kuyifunga. Byongeye kandi, ingaruka za piston z'intebe ya valve zakozwe neza, bigatuma ifunga umupira ukabije n'umuvuduko w'icyuma ubwacyo. Ubwoko bubiri bukurikira bwo gufunga umupira burashobora gukorwa.
7. Gufunga rimwe
(Kugabanya Umuvuduko mu buryo bwikora mu mwobo wo hagati wa Valve) Muri rusange, imiterere imwe yo gufunga ikoreshwa. Ni ukuvuga ko hariho gufunga hejuru gusa. Kubera ko intebe zo gufunga zikozwe mu mpande zo hejuru n'izo hasi zikoreshwa, umwobo w'imbere wa valve ushobora gutsinda ingaruka zo gufunga mbere y'isoko, kugira ngo intebe irekurwe mu mupira kandi ibone umuvuduko wikora ugana ku gice cyo hasi. Uruhande rwo hejuru: Iyo intebe igenda ku ruhande rw'umwobo, umuvuduko "P" ukoreshwa ku gice cyo hejuru (injira) utanga imbaraga zisubira inyuma kuri A1, Kubera ko A2 iri hejuru ya A1, A2-A1 = B1, imbaraga kuri B1 zizasunika intebe ku mupira kandi zigafunga igice cyo hejuru cyane.
Uruhande rwo hasi: Iyo igitutu "Pb" kiri muri valve Cavity cyiyongereye, imbaraga zikoreshwa kuri A3 ziba nyinshi kuruta izo kuri A4. Uko A3-A4=B2 ihinduka, itandukaniro ry'igitutu kuri B2 rizarenga imbaraga z'impeshyi kugira ngo intebe irekurwe mu mupira kandi ikureho igitutu cy'impeshyi ku gice cyo hasi nyuma, intebe n'umupira bizongera gufungwa munsi y'igikorwa cy'impeshyi.
8. Gufunga kabiri (Piston ebyiri)
Valve y'umupira w'umuyoboro wa trunnion ishobora gushushanywa ifite imiterere ibiri yo gufunga mbere na nyuma y'umupira kugira ngo ikoreshwe mu buryo bwihariye ndetse n'ibisabwa n'umukoresha. Ifite ingaruka ebyiri za piston. Mu gihe gisanzwe, valve muri rusange ifata intebe y'ibanze. Iyo intebe y'ibanze yangiritse igatera gusohoka, intebe y'ibanze ishobora gukora akazi ko gufunga no kongera ubwizerwe bwo gufunga. Intebe ifata imiterere ihujwe. Agace k'ibanze ni agace k'icyuma kuva ku cyuma kugera ku cyuma. Agace k'ibanze ni impeta ya fluorine rubber O ishobora kwemeza ko valve y'umupira ishobora kugera ku rwego rwo gufunga. Iyo itandukaniro ry'umuvuduko riri hasi cyane, intebe y'ibanze izakanda umupira mu gihe cy'impeshyi kugira ngo ikore intebe y'ibanze. Iyo itandukaniro ry'umuvuduko rizamutse, imbaraga zo gufunga intebe n'umubiri ziyongera ku buryo bifunga neza intebe n'umupira kandi bitume habaho imikorere myiza yo gufunga.
Gufunga by'ibanze: Hejuru y'amazi.
Iyo itandukaniro ry'umuvuduko riri hasi cyangwa nta tandukaniro ry'umuvuduko ririho, intebe ireremba izagenda ku ruhande rw'umugozi munsi y'ingufu z'impeshyi hanyuma inyure intebe yerekeza ku mupira kugira ngo ikomeze gufunga neza. Iyo intebe y'umugozi iri hejuru y'imbaraga zikoreshwa ku gace A1, A2- A1 = B1. Bityo, imbaraga ziri muri B1 zizasunika intebe yerekeza ku mupira maze igice cyo hejuru kibe gifunga neza.
9. Igikoresho cyo gufasha mu mutekano
Kubera ko valve y'umupira yakozwe ifite uburyo bwo gufunga bw'ibanze n'ubwa kabiri bufite ingaruka ebyiri za piston, kandi umwobo wo hagati ntushobora gukuraho umuvuduko wikora, valve y'umuvuduko igomba gushyirwa ku mubiri kugira ngo hirindwe ibyago byo kwangirika k'umuvuduko mwinshi mu mwobo w'umwobo bishobora kubaho bitewe no kwaguka k'ubushyuhe bw'umwuka. Guhuza valve y'umuvuduko wikora muri rusange ni NPT 1/2. Ikindi kintu kigomba kwitabwaho ni uko icyuma cy'umuvuduko wikora gisohoka mu kirere mu buryo butaziguye. Mu gihe gusukura mu kirere mu buryo butaziguye bitemerewe, turasaba ko valve y'umupira ifite imiterere yihariye yo gukuraho umuvuduko wikora mu mugezi wo hejuru igomba gukoreshwa. Reba ibi bikurikira kugira ngo umenye ibisobanuro birambuye. Nyamuneka yerekane uko bikurikirana niba udakeneye valve y'umuvuduko wikora cyangwa niba wifuza gukoresha valve y'umupira ifite imiterere yihariye yo gukuraho umuvuduko wikora mu mugezi wo hejuru.
Igishushanyo mbonera cy'ingenzi cy'ifungwa ry'umupira w'amashanyarazi wo hejuru n'uwo hasi
Igishushanyo mbonera cy'ishingiro ry'uburyo umuvuduko w'umuyoboro w'umupira umanuka ku mugezi wo hejuru no ku mugezi umanuka
12. Kurwanya ingese no kurwanya stress ya sulfide
Hasigaye uburyo bwo kwangirika ku bugari bw'urukuta rw'umubiri.
Urufatiro rw'icyuma cya karuboni, umugozi uhamye, umupira, intebe n'impeta y'intebe bishyirwamo nikeli ya shimi hakurikijwe ASTM B733 na B656. Byongeye kandi, hari ibikoresho bitandukanye birwanya ingese ku bakoresha bashobora guhitamo. Dukurikije ibyo abakiriya bakeneye, ibikoresho bya valve bishobora gutoranywa hakurikijwe NACE MR 0175 / ISO 15156 cyangwa NACE MR 0103, kandi kugenzura ubuziranenge no kugenzura ubuziranenge bigomba gukorwa mu gihe cyo gukora kugira ngo byuzuze ibisabwa mu bipimo kandi byuzuze ibisabwa mu rwego rwo gutanga sulfure.
