Vali z'umupiranavalve z'ibinyugunyugu ni ibyiciro bibiri by'ingenzi bya valve kandi bikoreshwa cyane. Valve y'umupira isaba gufunga neza ku bushyuhe bwinshi n'umuvuduko mwinshi n'umuvuduko muke. Valve z'ibinyugunyugu zikoreshwa cyane cyane mu mikorere ifite umuvuduko muke n'umuvuduko muke.

 

Hariho kandi ubwoko bwinshi bw'udupira tw'umupira n'udupira tw'ibinyugunyugu. Udupira tw'umupira dushobora kugabanywamo: utupira tw'icyuma dufunze neza, utupira tworoheje dufunze neza, utupira duto duto, utupira tudahinduka, utupira tw'igice cy'umupira, utupira tw'umupira duto dushushanyijeho ishusho ya V, nibindi.

 

Valve y'ikinyugunyugu igabanyijemo ibice bitatu: valve eshatu z'ikinyugunyugu zidasanzwe, valve ebyiri z'ikinyugunyugu zidasanzwe, valve y'ikinyugunyugu iri hagati, valve ikomeye yo gufunga ikinyugunyugu, valve yoroheje yo gufunga ikinyugunyugu.

 

Valve z'umupira n'iz'ibinyugunyugu ni valve zikoreshwa cyane. Hari ubwo zombi zishobora gukoreshwa mu buryo busanzwe, kandi mu bihe bimwe na bimwe by'akazi, imwe gusa ni yo ishobora gukoreshwa. Ibiranga ubwo bwoko bubiri bw'valve. Turasesengura muri make:

Valve y'umupira: valve y'inyuma yahindutse, igice cyo gufungura n'icyo gufunga ni uruziga, ibiranga ni ibi bikurikira:

1. Ubudahangarwa bw'amaraso ni buke. Iyo ifunguye neza, nta bice bibuza urujya n'uruza rw'amazi mu muyoboro;

2. Ishobora gufungwa neza iyo igitutu kiri hejuru n'ubushyuhe buri hejuru;

3. Ishobora gufungurwa no gufungwa vuba;

4. Kumenya uburyo bwo guhangana n'ubudahangarwa bwinshi n'ubudahangarwa bukomeye bw'ubudahangarwa binyuze mu kuvura ubudahangarwa;

5. Igice cy'umuyoboro w'amashanyarazi gifite imiterere ingana, gishobora kwihanganira neza umuvuduko w'imiyoboro kandi gishobora guhangana n'imimerere yo gukora ifite umuvuduko mwinshi.

 

Valve y'ikinyugunyugu: Igice cyo gufungura no gufunga ni isahani y'ikinyugunyugu yo mu bwoko bwa disiki, irangwa na:

1. Imiterere yoroshye, ingano nto kandi yoroshye kuyishyiraho;

2. Ingufu nto zo kwirinda amazi, gufungura no gufunga vuba;

3. Ishobora gukoreshwa ku mvange nini z'umurambararo;

4. Ahantu hatandukanye ho gufunga hashobora gukoreshwa ahantu hatandukanye, harimo n'aho hameze nk'ifu n'aho hameze nk'ibinyabutabire.

 

Ugereranyije na valve y'umupira, valve y'ibinyugunyugu ifite ubushobozi bwo kuziba buhoro, ariko muri valve nini, valve y'ibinyugunyugu ifite akarusho kadasanzwe ugereranyije na valve y'umupira; iyo ikoreshejwe mu kuvugurura umuvuduko w'amazi, valve y'ibinyugunyugu ifite ubushobozi bwo kuvugurura ingano nto, mu gihe valve y'umupira yo mu bwoko bwa V irashobora guhindurwa. Mu miyoboro ifite umuvuduko mwinshi, valve y'umupira ifite akarusho ugereranyije na valve y'ibinyugunyugu.
