Valve zo kugenzura, zizwi kandi nka valves zidasubiza amazi (NRVs), ni ingenzi mu buryo ubwo aribwo bwose bwo gukora imiyoboro y'amazi mu nganda cyangwa mu ngo. Zikoreshwa mu gukumira gusubira inyuma kw'amazi, kwemeza ko imikorere myiza y'imiyoboro y'amazi no gukumira kwangirika kw'amazi.

Valve zo kugenzura zikora mu buryo bworoshye. Umuvuduko uterwa n'amazi atembera mu miyoboro ufungura valve, kandi umuvuduko uwo ari wo wose ufunga valve. Ituma amazi atembera nta mbogamizi mu cyerekezo kimwe kandi igahita izima iyo umuvuduko ugabanutse. Nubwo ibi byoroshye, hari ubwoko butandukanye bwa valve zo kugenzura bufite imikorere n'ikoreshwa bitandukanye. Wamenya ute ubwoko bwa valve yo kugenzura ugomba gukoresha mu kazi kawe cyangwa mu mushinga wawe? Kugira ngo bigufashe guhitamo neza, dore ibisobanuro birambuye ku bwoko bwa valve zo kugenzura busanzwe.

Valve yo kugenzura ko wizunguza
Valve y'umweru ya PVC Swing CheckSwing Check ikoresha disiki iri imbere muri valve kugira ngo yemerere cyangwa ihagarike gutemba mu buryo bw'imiyoboro. Iyo amazi atembera mu cyerekezo gikwiye, igitutu gihatira disiki gufungura no kuyigumana ifunguye. Uko igitutu kigabanuka, disiki ya valve irafunga, bigatuma amazi atembera inyuma. Valve zo kugenzura Swing ziboneka mu bwoko butandukanye bw'ibikoresho, harimo PVC, CPVC, clear, na industrial.

Hari ubwoko bubiri bwa valve zo kugenzura swing dukwiye kwibandaho:

• Hejuru ifite Hinged – Muri iyi valvu yo kugenzura swing, disiki ifatanye n'imbere hejuru ya valvu n'agakingirizo gatuma disiki ifunguka kandi igafunga.

• Swashplate – Iyi vali yo kugenzura swing yakozwe mu buryo butuma vali ifunguka neza kandi igafunga vuba iyo umuvuduko w’amazi uri hasi. Ibi ibikora ikoresheje disiki ifite ishusho y’umusemburo kugira ngo vali ifunge vuba kurusha vali ifite impande zo hejuru. Byongeye kandi, disiki iri muri iyi vali yo kugenzura irareremba, bityo amazi atemba hejuru no hepfo y’ubuso bwa disiki.
Ubwo bwoko bw'udukingirizo two kugenzura bukoreshwa cyane mu gukumira umwuzure mu miyoboro y'amazi mabi no mu bikorwa byo kurinda inkongi. Bukoreshwa mu miyoboro itwara amazi, imyuka n'ibindi bikoresho by'ikoranabuhanga.

Kuzamuravalve yo kugenzura
Vali zo kugenzura lift zisa cyane na vali zo mu bwoko bwa globe. Zikoresha piston cyangwa imipira aho gukoresha disiki zikoreshwa na vali zo kugenzura zizunguruka. Vali zo kugenzura lift zigira akamaro cyane mu gukumira amazi kurusha vali zo kugenzura swing. Reka turebe izi vali ebyiri zo kugenzura lift:

• Piston – Ubu bwoko bwa valve yo kugenzura buzwi kandi nka valve yo kugenzura plug. Igenzura urujya n'uruza rw'amazi mu miyoboro binyuze mu ngendo ya piston mu cyumba cy'imashini. Hari igihe piston iba ifite isoko, ibi bikayifasha kuguma mu mwanya wayo ufunze iyo idakoreshwa.

Valve y'umupira ikoresha uburyo bwa PVC igenzura umupira • Valve y'umupira – Valve y'umupira ikoresha imbaraga z'isi gusa. Iyo hari igitutu gihagije mu mazi, umupira urazamuka, kandi iyo igitutu kigabanutse, umupira uramanuka ugafunga aho ufunguye. Valve y'umupira iboneka mu bwoko butandukanye bw'ibikoresho n'ubwoko: PVC: isobanutse neza kandi y'umukara, CPVC: ihurizo nyaryo kandi rito.

Kuzamuravalve zo kugenzurazikoreshwa mu bikorwa byinshi mu nganda nyinshi. Uzazibona mu ngo no mu nganda. Zikoreshwa mu nganda z'ibiribwa n'ibinyobwa, mu nganda za peteroli na gaze, ndetse no mu nganda zo mu mazi, ni ukuvuga nke.

Valve yo kugenzura ikinyugunyugu
Valve yo kugenzura ikinyugunyugu ni umwihariko kuko disiki yayo irazingira hagati kugira ngo amazi atemba. Iyo amazi asubiye inyuma, ibice bibiri bifungura kugira ngo bifunge valve ifunze. Iyi valve yo kugenzura, izwi kandi nka valve yo kugenzura ibyuma bibiri cyangwa valve yo kugenzura ibyuma bizingira, ikwiriye sisitemu z'amazi zifite umuvuduko muke ndetse na sisitemu zo gukwirakwiza gazi.

Valve yo kugenzura umubumbe
Valve zo kugenzura zifunga zigufasha gutangira no guhagarika urujya n'uruza rw'amazi muri sisitemu y'imiyoboro. Zitandukanye kuko zigufasha no kugenzura urujya n'uruza rw'amazi. Valve yo kugenzura umubumbe ni valve yo kugenzura ifite uburyo bwo kugenzura urujya n'uruza rw'amazi buhagarika urujya n'uruza rw'amazi hatitawe ku cyerekezo cyangwa igitutu cy'amazi. Iyo igitutu kiri hasi cyane, valve yo kugenzura ifunga mu buryo bwikora kugira ngo idasubira inyuma. Ubu bwoko bwa valve yo kugenzura bushobora gukora hakoreshejwe uburyo bwo kugenzura bwo hanze aho gukoresha uburyo bwo kugenzura urujya n'uruza rw'amazi, bivuze ko ushobora gushyiraho valve aho ifunze hatitawe ku rujya n'uruza rw'amazi.

Amavali yo kugenzura ikirere akoreshwa cyane mu buryo bwa boiler, inganda z'amashanyarazi, mu gukora peteroli no mu bikorwa by'umutekano w'umuvuduko mwinshi.

Ibitekerezo bya nyuma ku bijyanye na Check Valve
Ku bijyanye no gukumira gusubira inyuma kw'amazi, nta yandi mahitamo ashoboka uretse gukoresha valve yo kugenzura. Noneho ko umaze kumenya bike ku bwoko butandukanye bwa valve zo kugenzura, ugomba kuba ushobora guhitamo ikwiriye gukoreshwa.
