Indashyikirwa API Trunnion Mouted Fixed Type Ball Valve Umukozi Igiciro cy'uruganda rw'ubushinwa
Valve z'umupira wa Trunnion ni iki?
Avalve y'umupira w'imashinibivuze 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.
Itsindavalve y'umupirani ubwoko bwa valve ihindura ikirere ikoresha umupira ufite icyuho, ufite imyobo kandi udahinduka/ushyigikiwe kugira ngo ugenzure uburyo unyuramo.
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.
Ibintu by'ingenzi biranga valve za NORTECH Trunnion
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.
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.
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.
Gufunga igice cya kabiri: Kumanuka.
Iyo itandukaniro ry'umuvuduko riri hasi cyangwa nta tandukaniro ry'umuvuduko ririho, intebe ireremba izagenda mu buryo bw'uruhande rw'imashini munsi y'imashini ikora mu mpeshyi hanyuma isunikire intebe yerekeza ku mupira kugira ngo ikomeze gufunga neza. Iyo umuvuduko wa valve P wiyongereye, imbaraga zikoreshwa ku gace A4 k'intebe ya valve hejuru y'imbaraga zikoreshwa ku gace A3, A4- A3 = B1. Kubwibyo, imbaraga ziri kuri B1 zizasunika intebe yerekeza ku mupira maze igice cyo hejuru kikazifunga 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.
10. Imiterere yihariye yo kugabanya umuvuduko mu buryo bwikora ku mugezi wo hejuru
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'umupira hamwe n'imiterere yihariye irasabwa kugira ngo ihuze n'ibisabwa byo gukuraho umuvuduko wikora kandi irinde ko nta mwanduza w'ibidukikije wangiza ibidukikije. Mu miterere, umugezi wo hejuru ufata uburyo bwo gufunga bw'ibanze naho umugezi wo hasi ugafata uburyo bwo gufunga bw'ibanze n'ubwa kabiri. Iyo valve y'umupira ifunze, umuvuduko uri mu mwobo w'umupira ushobora gukuraho umuvuduko wikora ku mugezi wo hejuru, kugira ngo hirindwe akaga gaterwa n'umuvuduko w'umwobo. Iyo intebe y'ibanze yangiritse kandi ikava, intebe y'ibanze nayo ishobora gukora akazi ko gufunga. Ariko umwihariko ugomba kwitabwaho ku cyerekezo cy'umuvuduko w'umupira. Mu gihe cyo gushyiraho. Menya icyerekezo cyo hejuru n'icyo hasi. Reba ibishushanyo bikurikira byo gufunga valve ifite imiterere yihariye.
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.
Igiti kidapfa gutwikwa n'umuriro
13. Ishingiro ryo Kwagura
Ku bijyanye na valve ishyizwemo, inkingi yo kwagura ishobora gutangwa niba bikenewe ko ikoreshwa ku butaka. inkingi yo kwagura igizwe n'inkingi, valve yo gufunga, na valve yo gusohora amazi ishobora kwaguka ikagera hejuru kugira ngo byorohere kuyikoresha. Abakoresha bagomba kugaragaza ibisabwa n'uburebure bw'inkingi yo kwagura iyo batanze amabwiriza. Ku mpande zombi zikoresha amashanyarazi, pneumatic na pneumatic - hydraulic actuators, uburebure bw'inkingi yo kwagura bugomba kuva hagati y'umuyoboro kugera hejuru.
