3. Valve y'umupira
Valve y'umupira yavuye kuri valve ifunga. Igice cyayo cyo gufungura no gufunga ni uruziga, kandi uruziga ruzenguruka 90° ku murongo w'umugongo w'uruvange kugira ngo rugere ku ntego yo gufungura no gufunga. Valve y'umupira ikoreshwa cyane cyane ku miyoboro kugira ngo ikate, ikwirakwize, kandi ihindure icyerekezo cy'inzira y'umwuka. Valve y'umupira yakozwe ifite umwobo umeze nk'uwa V ifite kandi akazi keza ko kugenzura amazi.
Uruganda rwa TWS valve rutanga valve y'ibinyugunyugu iramba kandi ikora neza YD37A1X3-16Q, valve y'ibinyugunyugu ifite double flange concentric.D34B1X3-16Q, Valve y'ikinyugunyugu ifite flange ebyiri hakurikijwe Ser.13 cyangwa seri 14, BS5163/F4/F5 /ANSI CL150 valve y'irembo ifite agace ka rubber, Y-strainer, valve yo kuringaniza, irinda amazi mu mugongo.
3.1 Ibyiza:
① Ifite ubushobozi bwo kwirinda amazi mu rugero rwo hasi cyane (hafi 0).
② Kubera ko itazigera ihagarara mu gihe cyo kuyikoresha (mu gihe nta mavuta arimo), ishobora gushyirwa ku buryo bwizewe ku bintu byangiza n'ibinyobwa bishyuha cyane.
③ Ishobora gufunga neza mu gihe cy'umuvuduko n'ubushyuhe bwinshi.
④ Ishobora gufungura no gufunga byihuse. Igihe cyo gufungura no gufunga by'inyubako zimwe na zimwe ni amasegonda 0.05 kugeza 0.1 gusa, bigatuma ishobora gukoreshwa muri sisitemu zikora mu buryo bwikora z'intebe zo gupima. Iyo ufungura kandi ufunga valve vuba, nta ngaruka igira mu gihe cyo kuyikoresha.
⑤ Igice cyo gufunga cy’uruziga gishobora kwihagararaho mu buryo bwikora ku mupaka.
⑥-- Uburyo bwo gukora bufunze neza kuri vali.
Q⑦ Iyo valve ifunguye neza kandi ifunze neza, ubuso bwo gufunga bw'umubumbe n'intebe ya valve biba bitandukanyijwe n'ubwo buryo. Kubwibyo, ubwo buryo bunyura muri valve ku muvuduko mwinshi ntibuzatera kwangirika kw'ubuso bwo gufunga.
⑧ Ifite imiterere mito kandi ifite uburemere bworoshye. Ishobora gufatwa nk'imiterere y'ingufu nziza cyane ku buryo buciriritse.
⑨ ItsindavalveUmubiri ugizwe n'ibipimo bitandukanye. Cyane cyane ku miterere y'umubiri w'agasanduku gasutswe, gashobora kwihanganira umuvuduko uturuka ku muyoboro.
⑩ Igice cyo gufunga gishobora kwihanganira itandukaniro ry'umuvuduko mwinshi mu gihe cyo gufunga.
⑪ Valve y'umupira ifite agace ka valve gafite imashini ihambiriye neza ishobora gutwikirwa mu butaka, ikarinda ibice by'imbere bya valve kwangirika. Igihe ntarengwa cyo kuyikoresha gishobora kugera ku myaka 30, bigatuma iba valve nziza cyane ku miyoboro ya peteroli na gaze karemano.
3.2 Ingaruka mbi:
① Ikintu cy'ingenzivalveImpeta yo gufunga intebe ya valve y'umupira ni polytetrafluoroethylene (PTFE). Ntishobora kwinjira mu bintu hafi ya byose bya shimi kandi ifite imiterere yuzuye nko kuba ifite ubushobozi buke bwo gukururana, ubushobozi budahindagurika, ubushobozi bwo kurwanya gusaza, ubushobozi bwo gufunga bunini, n'ubushobozi bwiza bwo gufunga. Ariko, imiterere ya PTFE, harimo ubushobozi bwo kwaguka buri hejuru, ubushobozi bwo kumva ubukonje butemba, n'ubushobozi buke bwo gutwara ubushyuhe, bisaba ko igishushanyo cy'agapfundikizo k'agapfundikizo kigomba gukorwa kuri iyo miterere. Kubwibyo, iyo ibikoresho byo gufunga bikomera, ubwizigirwa bw'agapfundikizo buragabanuka. Byongeye kandi, urwego rwo kwirinda ubushyuhe bwa PTFE ni ruto, kandi ishobora gukoreshwa gusa ku bushyuhe buri munsi ya 180°C. Iyo ubushyuhe burenze iki giciro, ibikoresho byo gufunga bizasaza. Ukurikije ikoreshwa ry'igihe kirekire, muri rusange ikoreshwa gusa kuri 120°C.
② Imikorere yayo yo kugenzura irakomeye kurusha iya vali y'isi, cyane cyane kuri vali z'umwuka (cyangwa vali z'amashanyarazi).
5. Valve yo gushyiramo icyuma
Valve yo gushyiramo icyuma bivuga valve izunguruka aho igice cyo gufunga kiba gifite ishusho ya plunger. Mu kuzunguruka 90°, inzira yo gushyiramo icyuma ikorwa kugira ngo ihuze cyangwa itanduke n'inzira yo gushyiramo icyuma ku mubiri wa valve, bigatuma valve ifunguka cyangwa ifunga. Nanone yitwa cock, stopcock, cyangwa rotary gate. Imiterere ya plug ishobora kuba cylindrical cyangwa conical. Hari ubwoko bwinshi bwayo, harimo ubwoko bugororotse, ubwoko butatu, n'ubwoko bune. Ihame ryayo muri rusange risa n'iry'umupira.
5.1 Ibyiza:
① Irakwiriye gukoreshwa kenshi, ifite uburyo bwo gufungura no gufunga byihuse kandi byoroheje.
② Ubudahangarwa bw'amazi ni buke.
③ Ifite imiterere yoroshye, ingano ntoya, uburemere bworoheje, kandi yoroshye kuyibungabunga.
④ Ifite ubushobozi bwo gufunga neza.
⑤ Ntabwo bigengwa n'icyerekezo cyo gushyiraho, icyerekezo cy'amazi gishobora kuba nta mpamvu.
⑥ Nta gutigita kuhaba, kandi urusaku ni ruke.
5.2 Ingaruka mbi:
⑦ Ubuso bwo gufunga ni bunini cyane, bigatuma imbaraga ziyongera cyane kandi budahagije.
⑧ Ingano y'umurambararo wa valve iterwa n'uburemere bwayo bwite ni nke.
Mu ikoreshwa nyaryo, niba hakenewe valve nini, hagomba gukoreshwa imiterere y’icyuma gifunga inyuma, ibyo bikaba bishobora kugira ingaruka ku ngaruka zo gufunga.
Ibisobanuro birambuye, ushobora kuvugana n'umuntu ku buntuValve ya TWSuruganda.
