Umupiraibicuruzwa byahinduwe bivuye mumasake, umupira wumupira numuzingi wose nkuko gufungura gufungura no gufunga ibice (spool), ukoresheje umuzenguruko uzengurutse umurongo wikizunguruka cyikizunguruka cya dogere 90 kugirango ugere kumugambi wo gufungura no gufunga valve. Umupira wumupira ukoreshwa cyane cyane mugukata, gukwirakwiza no guhindura icyerekezo cyimyanda iciriritse mumuyoboro. Umupira wumupira hamwe na V-ifungura ifu nayo ifite imikorere myiza yo kugenzura ibintu.
Imipira yumupira ntabwo yoroshye gusa muburyo bwiza kandi nibyiza mugukora kashe, ariko kandi ntoya mubunini, urumuri muburemere, gake mukoresha ibikoresho bibisi, ntoya mubunini bwo kwishyiriraho, ntoya mugihe cyo gutwara, byoroshye mubikorwa kandi byoroshye kubona gufungura byihuse kandi gusoza. Nimwe mubwoko bwihuta bwikura rya valve mumyaka mirongo ishize. Gukoresha imipira yumupira ni nini cyane. Ubwoko nubwinshi bwimipira yumupira iracyiyongera. Barimo gutera imbere mu cyerekezo cy'ubushyuhe bwo hejuru, umuvuduko mwinshi, orifice nini, kashe ndende, ubuzima bumara igihe kirekire, imikorere myiza yo kugenzura no gukora byinshi. Kwizerwa kwabo nibindi bipimo ngenderwaho bigeze ku rwego rwo hejuru, kandi byasimbuye igice cyo gukoresha amarembo, amarembo yisi na trottle. Hamwe niterambere ryiterambere rya tekinoroji ya valve, izakoreshwa cyane mugihe gito giteganijwe, cyane cyane mumiyoboro ya peteroli na gaze, ibice bitunganya peteroli hamwe ninganda za kirimbuzi. Mubyongeyeho, mu zindi nganda za kaliberi nini nini yo hagati, urwego ruciriritse kandi ruto, imipira yumupira nayo izahinduka imwe mubwoko bwiganje.
Gutunganya neza, kugiciro cyinshi, ubushyuhe bwo hejuru ntabwo byoroshye gukoresha, nkumwanda uri mumuyoboro, byoroshye gucomeka numwanda, biganisha kuri valve ntishobora gufungura.
Imipira yumupira ishyirwa mubikorwa:
1. Bypass valve: imipira yumupira muri rusange ifunguye mumazi ahamye, bityo rero Bypass igomba kubanza gushyirwaho, ni ukuvuga impande zombi zuzuye amazi.
2. Umuyaga wo mu kirere: Iyo wuzuza amazi, umwuka urakurwaho kandi buoy ifunga valve yonyine; mugihe cyo kuvoma amazi, buoy itonyanga yonyine hamwe numwuka winyongera.
3.
4. Kwishyiriraho no gufata neza imipira yumupira bigomba kwitondera ibibazo bikurikira:
Komeza umwanya uzunguruka wumukono wa valve.
⑵ Ntishobora gukoreshwa nka trottle.
