Valve y'umupira w'amashanyarazi (Electric trunnion ball valve) ni iki?
AnValve y'umupira w'amashanyarazibivuze 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.
Ibyiza byo gushushanya umupira w'imashini ni uko amashanyarazi adakora neza, koroshya imikorere, kudakoresha neza intebe (Kwitandukanya kw'inkingi n'umupira birinda imitwaro yo ku ruhande no kwangirika kw'intebe zo hasi birushaho kunoza imikorere n'igihe cyo kuyikoresha), gukora neza cyane ku muvuduko mwinshi no hasi (uburyo butandukanye bwo gufunga bukoreshwa mu gufunga umupira uhagaze mu gihe udafite umuvuduko mwinshi no mu gihe cyo kuyikoresha).
Ibintu by'ingenzi bigize valve y'umupira w'amashanyarazi ya NORTECH
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.
3.Igikoresho cyo Gufunga mu Buryo bwihutirwa
Udupira tw’umupira dufite umurambararo urenze cyangwa ungana na 6' (DN150) twose twakozwe hakoreshejwe icyuma gifunga ku gice cy’intebe n’icyicaro. Iyo impeta y’intebe cyangwa impeta y’inkingi O yangiritse bitewe n’impanuka, icyuma gifunga kijyanye nayo gishobora guterwa n’icyuma gifunga kugira ngo hirindwe ko impeta y’intebe n’icyicaro ivamo amazi. Iyo bibaye ngombwa, uburyo bwo gufunga bw’inyongera bushobora gukoreshwa mu koza no gusiga amavuta ku ntebe kugira ngo ikomeze kugira isuku.
Igikoresho cyo guteramo inshinge gifunga
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.
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.
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.
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.
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
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
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.
