Mu nkuru ibanziriza iyi, twavuze ku byerekeye gate na globe valves, uyu munsi tugiye ku mashini zikoresha ibyuma binini (butterfly valves) no kugenzura ibyuma binini, bikunze gukoreshwa mu gutunganya amazi.
1. Valve y'ikinyugunyugu.
Valve y'ikinyugunyuguni valve izunguruka ikoresha disiki (izwi kandi nk'igice cy'ikinyugunyugu) ifungura kandi igafunga kugira ngo izunguruke 90° cyangwa hafi 90° kugira ngo ifungure kandi ifunge umuyoboro. Inzira ya disiki ya valve y'ikinyugunyugu irimo guhanagura, bityo valve nyinshi z'ikinyugunyugu zishobora gukoreshwa ku byuma bifite uduce duto duto duhagaze.
Valve z'ibinyugunyugu zikoreshwa cyane zirimo valve za wafe na valve z'ibinyugunyugu zifite flange. Valve y'ibinyugunyugu yo mu bwoko bwa Wafer ikoreshwa mu guhuza valve hagati y'imiyoboro ibiri ikoresheje bolts, naho valve y'ibinyugunyugu yo mu bwoko bwa flange iri kuri valve, kandi flanges zo ku mpera zombi za valve zihujwe n'umuyoboro ukoresheje bolts.
Ibiranga:
1.Ingano nto, uburebure bugufi, imiterere yoroshye n'uburemere bworoheje.
2. Byoroshye gukoresha, gufungura no gufunga byihuse, bisaba gusa kuzunguruka disiki kuri 90° kugira ngo uyifungure kandi uyifunge.
3. Uburyo bwiza bwo gufunga no gukosora. Kubera ko rubber ikoreshwa nk'impeta yo gufunga, gukanda no kwihanganira ni byiza (ni ukuvuga ko itakomera), bityo uburyo bwo gufunga ni bwiza. . Agace k'ingufu gashobora gufungurwa hagati ya 15° na 70°, kandi gashobora kugenzura amazi neza.
4. Umuvuduko muto wo gukora no kudakoresha amazi. Dukurikije ibipimo, kudakoresha amazi kw'udupira tw'ibinyugunyugu ni munsi y'uko bimeze ku bundi bwoko bw'udupira uretse udupira tw'umupira.
5. Bitewe n'aho ibikoresho bifunga bigarukira, igitutu cy'imikorere n'ubushyuhe bw'imikorere bya valve y'ikinyugunyugu ni bike cyane.
2. Kugenzura Valve
Imikoreshereze n'ibiranga:
Valve yo kugenzurani valve ikoreshwa mu gukumira gusubira inyuma kw'ibice by'amashanyarazi mu muyoboro, irafungura iyo icyuma gitemba kimanuka hanyuma kigafunga mu buryo bwikora iyo icyuma gitemba kivuye inyuma. Ubusanzwe ikoreshwa mu muyoboro ntiyemerera icyuma gutemba mu cyerekezo gitandukanye, kugira ngo hirindwe gusubira inyuma kw'icyuma gikoreshwa mu buryo bw'amashanyarazi kwangiza ibikoresho n'ibice byacyo. Iyo pompe ihagaritse gukora, ntugatere imashini izunguruka ihindura imashini. Mu muyoboro, akenshi genzura valve na valve zifunganye zikoreshwa mu buryo bukurikiranye. Ibi biterwa no kudafunga neza valve igenzura, iyo icyuma gifunganye ari gito, hazabaho igice gito cy'ibice by'amashanyarazi, hakenewe valve zifunganye kugira ngo umuyoboro ufunge. Valve yo hasi nayo ni valve igenzura, igomba kwinjizwa mu mazi, by'umwihariko ishyirwa muri pompe ntishobora kwiyima cyangwa ngo ikore umuyoboro wo gukurura amazi udafite vacuum.
Uburyo bwo gutunganya amazi busanzwe n'uburyo bwo gupima ibibazo
Valve mu gihe runaka ikora, hazabaho amakosa atandukanye. Ubwa mbere, umubare w'ibice bijyanye n'imiterere ya valve, ibice byinshi ni amakosa asanzwe. Ubwa kabiri, hamwe n'igishushanyo mbonera cya valve, uko ikorwa, uko ishyirwa, imiterere y'imikorere, ibyiza n'ibibi byo kuyibungabunga. Ibibazo rusange bya valve bidakoresha ingufu bigabanyijemo ibyiciro bine.
1. Kunanirwa kwangiza ikoranabuhanga
Ikosa ry'igikoresho cyo kohereza amakuru rikunze kugaragara nko kugongana kw'imizingo y'imashini, kudahinduka cyangwa imashini idakora. Impamvu ni izi: imashini ifungwa igihe kirekire nyuma y'ingese; gushyiraho no gukoresha nabi imigozi y'imashini cyangwa imashini; irembo rifungirwa mu mubiri w'imashini n'ibintu biturutse mu mahanga; irembo rikunze gufungura igice kimwe n'igice, bitewe n'amazi cyangwa izindi ngaruka bigatuma imashini zifunga neza, insinga z'imashini zigacika, zigacika, zigakuruma; igitutu cyo gupakira kiba gikomeye cyane, gifata imashini; imashini iba iri hejuru cyangwa igafunga ibice. Kubungabunga bigomba kuba ibikoresho byo gutwara birimo amavuta. Ukoresheje urufunguzo, no gukanda buhoro buhoro, ushobora gukuraho ikibazo cyo gufunga, kongera hejuru; guhagarika gusana cyangwa gusimbuza imashini.
2. Umubiri w'agace k'amaraso kangiritse wangiritse
Impamvu zangiritse ku mubiri w'imvange: kugabanuka k'ubudahangarwa bw'ibikoresho bya valavu; guhagarara kw'umuyoboro w'amazi; impinduka z'umuvuduko w'umuyoboro cyangwa ubushyuhe; inyundo y'amazi; gufunga valavu idakora neza n'ibindi. Igomba gukuraho vuba impamvu ziturutse inyuma no gusimbuza ubwoko bumwe bw'ibice bya valavu cyangwa valavu.
3. Gutemba kw'imvange
Gusohoka kwa valve bigaragazwa n'ibi bikurikira: gusohoka kwa valve core stem; gusohoka kwa gland; gusohoka kwa gasket flange. Impamvu zikunze kugaragara ni: kwangirika kwa valve stem (valve shaft), kwangirika kwa corruption, gufunga imyobo yo hejuru, gukurura; gusaza kwa splice, gusohoka kwa gland; gufunga flange bolts, gusohora flange bolts. Gusana kugira ngo wongere, usimbuze icyuma gifunga; gusimbuza nut nshya kugira ngo wongere aho bolt ifata.
Uko byagenda kose, niba gusana bisanzwe, kubungabunga bidakozwe ku gihe, bishobora gutuma amazi apfa ubusa, cyangwa se bikaba bibi kurushaho, bigatuma sisitemu yose ihagarara. Kubwibyo, abakozi bashinzwe kubungabunga valve bagomba kuba bareba impamvu zatumye valve ipfa kugira ngo bakore akazi keza, bamenyere kandi bakore neza amabwiriza n'imikorere ya valve, bavure ku gihe kandi mu buryo buhamye ibibazo bitandukanye byihutirwa, kugira ngo barinde imikorere isanzwe y'umuyoboro wo gusukura amazi.
4. gufungura no gufunga kwa valve ntabwo ari byiza
Gufungura no gufunga valve bidakora neza kuri valve idafunguye cyangwa ngo ifunze, valve ntishobora gukoreshwa mu buryo busanzwe. Impamvu ni izi: kwangirika kw'imitsi ya valve; irembo rifunze cyangwa irembo rifunze igihe kirekire mu gihe cy'ingese; irembo rizimye; ibintu by'amahanga byafatiwe ku buso bufunga cyangwa mu mwobo wo gufunga; ibice by'itumanaho byangiritse, gufunga. Guhura n'ikibazo cyavuzwe haruguru, kubungabunga ibice by'itumanaho bya sitrojeni; gufungura no gufunga valve kenshi no gukubita ibintu by'amahanga; gusimbuza valve.
