Vali zo mu irembonavalve z'ibinyugunyugubikoreshwa nk'amadirishya yo kugenzura umuvuduko w'amazi mu miyoboro. Birumvikana ko hakiri uburyo bwo guhitamo amadirishya y'ibinyugunyugu n'amadirishya y'irembo.
Mu miyoboro y'amazi, kugira ngo ugabanye uburebure bw'ubutaka butwikiriye imiyoboro, umurambararo rusange w'umuyoboro munini ufite valve y'ibinyugunyugu, kandi niba uburebure bw'ubutaka butwikiriye butari bunini, gerageza guhitamo valve y'irembo, ariko igiciro cya valve y'irembo ifite imiterere imwe kiri hejuru y'igiciro cya valve y'ibinyugunyugu. Ku bijyanye n'umurongo w'imbibi, buri gace gakwiye gusuzumwa hakurikijwe uko ibintu bimeze. Ukurikije uko ikoreshwa mu myaka icumi ishize, imbogamizi ya valve y'ibinyugunyugu iri hejuru y'iyavalve y'irembo, bityo rero ni ngombwa kwitondera kwagura intera y'ikoreshwa rya valve y'irembo niba ibisabwa bibyemerera.
Mu myaka ya vuba aha, abakora valve benshi bo mu ngo bakoze kandi bigana valve zoroshye zo gufunga, zifite ibi bikurikira kurusha valve zisanzwe zo gufunga cyangwa zihuza:
ItsindavalveUmubiri n'agapira k'ikirahure cyoroshye bicurwa hakoreshejwe uburyo bwo gucukura neza, bukorwa icyarimwe, ntabwo bukozwe mu mashini, kandi ntibukoresha impeta z'umuringa zifunga, bigatuma ibyuma bitagira feri bizigama.
Nta mwobo uri hasi ku gice cyo hasi cy'ikirarovalve yoroshye yo gushyiramo agapapuro, nta kwirundanya kw'ibisigazwa, hamwe n'igipimo cyo gutsindwa kwavalve y'irembogufungura no gufunga biri hasi.
Agapira k'agapira koroshye gafite umupfundikizo gafite ingano imwe kandi gashobora guhindurwamo.
Bityo rero, valve yoroshye yo gushyiramo amazi izaba ubwoko inganda zitanga amazi zishimiye gukoresha. Kuri ubu, umurambararo wa valve yoroshye yo gushyiramo amazi ikorerwa mu Bushinwa ni mm 1500, ariko umurambararo w'inganda nyinshi ni hagati ya mm 80-300, kandi haracyari ibibazo byinshi mu nganda zo mu gihugu. Igice cy'ingenzi cya valve yoroshye yo gushyiramo amazi ni plate ya valve ifite rubber, kandi ibisabwa mu bya tekiniki bya valve ifite rubber ni byinshi, kandi si inganda zose z'abanyamahanga zishobora kubigeraho, kandi akenshi igurwa kandi igateranywa mu ruganda ifite ubuziranenge bwizewe.
Agace k'umuringa k'agace koroshye ko mu rugovalve y'iremboishyirwa hejuru y’isahani y’urukiramende, isa n’imiterere y’urukiramende rw’irembo, kandi urukiramende rw’urukiramende rw’isahani y’urukiramende rworoshye gukurwaho bitewe n’uburyo urukiramende rukora. Ku rugaga rw’irembo rworoshye rw’isosiyete y’amahanga, urukiramende rw’umuringa rushyirwa mu rukiramende rukozwe mu rukiramende kugira ngo rube ikintu cyose, ibyo bikaba birenga inenge zavuzwe haruguru, ariko ubwinshi bw’urukiramende n’umubiri w’urukiramende ni byinshi.
Ariko, mu gihe cyo gufungura no gufunga valve yoroshye yo gufunga, ntigomba gufungwa cyane, igihe cyose ingaruka zo guhagarika amazi zibonetse, bitabaye ibyo ntibyoroshye gufungura cyangwa gukuraho utwenda twa kabutura. Uruganda rukora valve, mu igerageza ry'umuvuduko wa valve, rukoresha torque wrench kugira ngo rugenzure urwego rwo gufunga, nk'abakoresha valves bo mu kigo cy'amazi nabo bagomba gukurikiza ubu buryo bwo gufungura no gufunga.
Ni irihe tandukaniro riri hagati yo gukoreshavalve z'ibinyugunyugunavalve zo mu irembo?
Dukurikije imikorere n'imikoreshereze ya valve y'irembo na valve y'ibinyugunyugu, ubwiyongere bw'amazi ya valve y'irembo ni buto, imikorere yo gufunga ni myiza, kuko icyerekezo cy'amazi ya valve y'irembo n'igice cy'amazi ari inguni ihagaze, iyo valve y'irembo idafite aho iherereye mu gikoresho cyo gukingura valve, igikoresho cyo gukingura valve gituma valve inyeganyega, kandi biroroshye kwangiza valve y'irembo.
Valve y'ibinyugunyugu, izwi kandi nka valve yo kugonga, ni imiterere yoroshye ya valve igenzura, ishobora gukoreshwa mu kugenzura umuyoboro w'amashanyarazi make. Valve y'ibinyugunyugu yerekeza ku gice cyo kuzimya (disiki cyangwa plate y'ibinyugunyugu) nk'ikimenyetso, kizenguruka ku mugozi w'ibinyugunyugu kugira ngo haboneke uburyo bwo gufungura no gufunga ubwoko bw'ibinyugunyugu, valve ishobora gukoreshwa mu kugenzura urujya n'uruza rw'amazi atandukanye nk'umwuka, amazi, umwuka, ibintu bitandukanye byangiza, ibyondo, amavuta, ibyuma bivamo amazi n'ibinyabutabire bikoresha imirasire. Ifite uruhare runini mu gukata no gukanda ku muyoboro. Igice cyo gufungura no gufunga cy'ibinyugunyugu ni plate y'ibinyugunyugu ifite ishusho ya disiki, izenguruka ku murongo wayo mu mubiri w'ibinyugunyugu, kugira ngo igere ku ntego yo gufungura no gufunga cyangwa guhindura.
Isahani y'ikinyugunyugu itwarwa n'umugongo w'ikinyugunyugu, kandi iyo ihinduye uburebure bwa dogere 90, ishobora kurangiza ifungura n'ifunga. Mu guhindura inguni y'impinduka z'ikinyugunyugu, umuvuduko w'amazi urashobora kugenzurwa.
Imiterere y'akazi n'uburyo bukoreshwa:Valve y'ikinyugunyuguikwiriye gutwara imiyoboro itandukanye y’amazi yangiza n’atayingiza mu buryo bw’ubuhanga nko mu itanura, gaze y’amakara, gaze karemano, gaze y’ibikomoka kuri peteroli, gaze yo mu mujyi, umwuka ushyushye n’ukonje, gushongesha imiti no kurengera ibidukikije, gutanga amazi n’imiyoboro y’amazi mu nyubako, n’ibindi, kandi ikoreshwa mu kugenzura no kugabanya urujya n’uruza rw’amazi.
Valve y'irembo (valve y'irembo) ni igice cyo gufungura no gufunga cy'irembo, icyerekezo cy'irembo kiba gihagaze neza ugereranije n'icyerekezo cy'amazi, valve y'irembo ishobora gufungurwa no gufungwa byuzuye gusa, ububabare bw'ibipimo by'umuryango buratandukanye, akenshi 5°, iyo ubushyuhe buri hagati butari hejuru, ni 2°52′. Kugira ngo yongere ubushobozi bwo gukora no gukosora inguni yo gufunga mu gihe cyo gutunganya, ubu bwoko bw'imfizi bwitwa ram ya elastic.
Ubwovalve y'iremboifunze, ubuso bwo gufunga bushobora kwishingikiriza gusa ku gitutu kiri hagati kugira ngo bufunze, ni ukuvuga ko, kwishingikiriza gusa ku gitutu kiri hagati kugira ngo bukandagire ubuso bwo gufunga bw'impeta ku ntebe ya valve iri ku rundi ruhande kugira ngo hamenyekane ko ubuso bwo gufunga, ari bwo bwifunga. Valve nyinshi zo ku irembo zifunze ku ngufu, ni ukuvuga ko iyo valve ifunze, ram igomba gukandagirwa ku ngufu ku ntebe ya valve n'imbaraga zo hanze kugira ngo hamenyekane ko ubuso bwo gufunga bufunze neza.
Uburyo bwo kugenda: Igice cy'irembo cya valve y'irembo kigenda mu murongo ugororotse hamwe n'umugongo wa valve, witwa kandi valve y'irembo ry'inkoni ifunguye. Akenshi hari umugozi wa trapezoidal ku nkoni yo kuzamura, unyuze mu giti kiri hejuru ya valve n'umuyoboro w'ubuyobozi ku mubiri wa valve, ingendo izunguruka ihinduka umurongo, ni ukuvuga ko torque y'imikorere ihinduka igikoresho cyo gukora. Iyo valve ifunguye, iyo uburebure bwa ram lift bungana n'inshuro 1:1 z'umurambararo wa valve, urujya n'uruza rw'amazi ntirushobora kubangamira, ariko iyi myanya ntishobora gukurikiranwa mu gihe cyo gukora. Mu ikoreshwa nyaryo, igaragazwa n'impande z'umugongo, ni ukuvuga, aho idashobora gufungurwa, nk'aho ifunguye neza. Kugira ngo harebwe imihindagurikire y'ubushyuhe ishingiye ku gufunga, ikunze gufungurwa ikagera ku mwanya wo hejuru, hanyuma igasubizwa inyuma ku mpande ya 1/2-1 nk'aho valve ifunguye neza. Kubwibyo, aho valve ifunguye neza igenwa n'aho ram (ni ukuvuga stroke). Hari agace k'umugozi k'irembo gaherereye ku irembo, maze urukiramende rugazunguruka kugira ngo agace k'umugozi kazunguruke, hanyuma isahani y'irembo igaterurwa, iyi valve yitwa valve y'irembo y'inkoni izunguruka cyangwa valve y'irembo y'inkoni yijimye.
