2.5 Valve yo gushyiramo plagi

Valve yo gushyiramo icyuma ni valve ikoresha agace k'icyuma gafite umwobo wo kwinjira nk'igice cyo gufungura no gufunga, kandi agace k'icyuma gahindura icyuma kugira ngo kibone gufungura no gufunga. Valve yo gushyiramo icyuma ifite imiterere yoroshye, gufungura no gufunga byihuse, gukora byoroshye, kudakoresha amazi menshi, ibice bike n'uburemere bworoheje. Valve zo gushyiramo icyuma ziboneka mu bwoko bugororotse, butatu n'ubune. Valve yo gushyiramo icyuma ikoreshwa mu guca icyuma, naho valve zo gushyiramo icyuma zifite inzira eshatu n'ebyiri zikoreshwa mu guhindura icyerekezo cy'icyuma cyangwa kuyobya icyuma.

2.6Valve y'ikinyugunyugu

Valve y'ikinyugunyugu ni icyuma gifata amapine kizunguruka 90° kizenguruka umurongo uhamye mu gice cy'umubiri w'ikinyugunyugu kugira ngo kirangize akazi ko gufungura no gufunga. Valve z'ikinyugunyugu ni ntoya, zoroheje kandi zoroshye mu miterere, zigizwe n'ibice bike gusa.

Kandi ishobora gufungurwa no gufungwa vuba uzunguruka gusa kuri dogere 90°, byoroshye kuyikoresha. Iyo valve y'ikinyugunyugu iri mu mwanya wayo ufunguye neza, ubugari bw'ikinyugunyugu ni bwo buryo bwonyine butuma icyuma gitemba mu mubiri w'ikinyugunyugu. Kubwibyo, kugabanuka k'umuvuduko uterwa na valve ni gato cyane, bityo ikaba ifite imiterere myiza yo kugenzura amazi. Valve z'ikinyugunyugu zigabanyijemo ubwoko bubiri bwo gufunga: agafunga koroshye gakozwe mu buryo bwa elastic na agafunga gakomeye k'icyuma. Valve yo gufunga ikozwe mu buryo bwa elastic, impeta yo gufunga ishobora gushyirwa mu mubiri w'ikinyugunyugu cyangwa igashyirwa ku nkengero z'ikinyugunyugu. Ifite ubushobozi bwo gufunga neza kandi ishobora gukoreshwa mu gufunga, imiyoboro y'amazi ikoreshwa mu buryo buciriritse n'ibikoresho byangiza. Valve zifite agafunga k'icyuma muri rusange zimara igihe kirekire kurusha valve zifite agafunga ko mu buryo bwa elastic, ariko biragoye kuzifunga burundu. Akenshi zikoreshwa mu bihe aho kugabanuka k'umuvuduko n'umuvuduko bihinduka cyane kandi imikorere myiza yo gufunga ikenewe. Agafunga k'icyuma gashobora kwihuza n'ubushyuhe bwinshi, mu gihe agafunga ko mu buryo bwa elastic gafite ingaruka mbi zo kugabanywa n'ubushyuhe.

2.7Valve yo kugenzura

Valve yo kugenzura ni valve ishobora gukumira urujya n'uruza rw'amazi mu buryo bwikora. Disiki ya valve yo kugenzura irafungura bitewe n'umuvuduko w'amazi, maze amazi akava ku ruhande rw'aho yinjira ajya ku ruhande rw'aho asohokera. Iyo umuvuduko ku ruhande rw'aho yinjira uri munsi y'aho asohokera, valve ihita ifunga bitewe n'umuvuduko w'amazi, uburemere bwayo n'ibindi bintu bituma amazi adasubira inyuma. Dukurikije imiterere yayo, ishobora kugabanywamo valve yo kugenzura hejuru na valve yo kugenzura swing. Ubwoko bwo kuzamura bufite uburyo bwo gufunga neza kandi bufite ubushobozi bwo kurwanya amazi kurusha ubwoko bwo guhindura. Ku bijyanye n'aho ipompe ikura, hagomba gukoreshwa valve yo hasi. Akazi kayo ni ukuzuza amazi mu muyoboro w'ipompe mbere yo gutangira pompe; nyuma yo guhagarika pompe, komeza umuyoboro w'ipompe n'umubiri w'ipompe mu gihe witegura kongera gutangira. Valve yo hasi muri rusange ishyirwa gusa ku muyoboro uhagaze ku muyoboro w'ipompe, kandi icyuma gituruka hasi kiva hejuru kijya hasi.

2.8Valve ya diaphragm

Igice cyo gufungura no gufunga cy'agace k'inyuma ni agace k'inyuma, gashyirwa hagati y'igice cy'inyuma n'igipfundikizo cy'agace k'inyuma.

Igice cyo hagati cy’agace k ...

3. Amabwiriza akoreshwa cyane mu guhitamo valve

3.1 Amabwiriza yo guhitamo valve y'irembo

Mu bihe bisanzwe, valve zo mu irembo zigomba kuba nziza. Uretse kuba zikwiriye umwuka ushyushye, amavuta n'ibindi bikoresho, valve zo mu irembo zikwiriye kandi ibikoresho birimo ibintu bikomeye kandi bifite ubushyuhe bwinshi, kandi zikwiriye valve zo mu buryo bwo guhumeka no mu buryo bwo gusohora umwuka muke. Ku bikoresho birimo ibice bikomeye, igice cy'icyuma cyo mu irembo kigomba kuba gifite umwobo umwe cyangwa ibiri yo gusukura. Ku bikoresho bifite ubushyuhe buke, valve zihariye zo mu irembo zigomba guhitamo.

3.2 Amabwiriza yo guhitamo valve zo guhagarara

Valve yo guhagarara ikwiriye imiyoboro ifite ubushobozi bwo kugabanya umuvuduko w'amazi, ni ukuvuga ko kugabanuka k'umuvuduko bitafatwa cyane, ndetse n'imiyoboro cyangwa ibikoresho bifite ubushyuhe bwinshi n'umuvuduko mwinshi. Ikwiriye imiyoboro y'umwuka n'indi miyoboro iciriritse ifite DN <200mm; valve nto zishobora gukoresha valve ziciwe. Valve, nka valve z'urushinge, valve z'ibikoresho, valve z'ingero, valve zerekana umuvuduko, nibindi; valve zo guhagarara zifite uburyo bwo guhindura umuvuduko w'amazi cyangwa umuvuduko, ariko ntabwo ari ngombwa guhindura neza, kandi umurambararo w'umuyoboro ni muto, bityo valve yo guhagarara cyangwa valve yo gufunga igomba gukoreshwa Valve; Ku bikoresho by'uburozi bwinshi, valve yo guhagarara ifunze neza igomba gukoreshwa; icyakora, valve yo guhagarara ntigomba gukoreshwa ku bikoresho bifite ubushyuhe bwinshi n'ibice birimo uduce dushobora kwangirika, kandi ntigomba gukoreshwa nk'valve yo guhumeka n'ivave muri sisitemu nto y'umwuka.

3.3 Amabwiriza yo guhitamo valve y'umupira

Vali z'umupira zikwiriye ibikoresho bikoresha ubushyuhe buke, umuvuduko mwinshi, n'ubushyuhe bwinshi. Vali nyinshi z'umupira zishobora gukoreshwa mu bikoresho bifite uduce duto duto, kandi zishobora no gukoreshwa mu bikoresho birimo ifu n'ibice bito hakurikijwe ibisabwa mu gufunga; vali z'umupira zuzuye ntizikwiriye kugenzura amazi, ariko zikwiriye mu bihe bisaba gufungura no gufunga vuba, byoroshye gushyira mu bikorwa. Guhagarika byihutirwa mu mpanuka; akenshi bigirwa inama mu miyoboro ifite ubushobozi bwo gufunga neza, kwangirika, imiyoboro igabanuka, gufungura no gufunga vuba, gukata umuvuduko mwinshi (itandukaniro ry'umuvuduko munini), urusaku ruto, ikintu cyo gukwirakwiza umwuka, imbaraga nto zo gukora, n'ubudahangarwa buke bw'amazi. Koresha vali z'umupira; vali z'umupira zikwiriye ibikoresho byoroheje, gukata umuvuduko muto, n'ibikoresho byangiza; vali z'umupira nazo ni vali nziza cyane ku bikoresho bikoresha ubushyuhe buke n'ubushyuhe bwinshi. Ku miyoboro n'ibikoresho bifite ibikoresho bikoresha ubushyuhe buke, vali z'umupira z'ubushyuhe buke zifite ibifuniko bya vali; hitamo Iyo ukoresha vali y'umupira ireremba, ibikoresho byayo bigomba gutwara umutwaro w'umupira n'ibikoresho bikora. Vali z'umupira nini zikenera imbaraga nyinshi mu gihe cyo gukora. Valive z'umupira zifite DN ≥ 200mm zigomba gukoresha ibikoresho byo kohereza inzoka; valive z'umupira zihamye zikwiriye uburebure bunini n'ikirere gifite umuvuduko mwinshi; byongeye kandi, valive z'umupira zikoreshwa mu miyoboro y'ibikoresho by'uburozi bwinshi n'ibikoresho bishya bigomba kuba bifite inyubako zirinda umuriro kandi zirwanya imihindagurikire y'ikirere.
