Valve y'iremboni umusaruro w’impinduramatwara mu nganda. Nubwo hari imiterere y’ama-valve, nka globe valves na plug valves, imaze igihe kinini ihari, ama-gate valves amaze imyaka myinshi ari yo akomeye muri urwo rwego, kandi vuba aha ni bwo batanze isoko rinini ku bishushanyo by’ama-valve na butterfly valves.

Itandukaniro riri hagati ya valve y'irembo na valve y'umupira, valve yo gushyiramo plug na valve y'ikinyugunyugu ni uko ikintu gifunga, cyitwa disc, gate cyangwa occluder, kizamuka hasi ku giti cya valve cyangwa spindle, kiva mu nzira y'amazi kikinjira hejuru ya valve, yitwa bonnet, hanyuma kikazenguruka muri spindle cyangwa spindle mu buryo bwinshi. Izi valve zifunguka mu buryo bugororotse zizwi kandi nka multi turn cyangwa linear valves, bitandukanye na quarter turn valves, zifite stem izenguruka dogere 90 kandi isanzwe idazamuka.

Vali zo mu rugi ziboneka mu bikoresho byinshi bitandukanye kandi zipima umuvuduko. Zifite ingano zitandukanye kuva kuri NPS ikwiranye n'intoki zawe kuva kuri ½ santimetero kugeza kuri NPS nini ya santimetero 144. Vali zo mu rugi zigizwe n'udupira, udupira two gushongesha, cyangwa ibice byakozwe hakoreshejwe gusudira, nubwo imiterere y'udupira ari yo igaragara cyane.

Kimwe mu bintu byifuzwa cyane ku mavalue y'irembo ni uko ashobora gufungurwa neza nta nkomyi nyinshi cyangwa gukururana mu myobo y'amazi. Uburyo bwo kwirinda amazi butangwa na value y'irembo ifunguye bungana n'ubw'igice cy'umuyoboro gifite ingano imwe y'aho amazi anyura. Kubwibyo, value z'irembo ziracyatekerezwaho cyane mu kuziba cyangwa kuzimya. Mu mazina amwe na amwe y'amavalue, value z'irembo zitwa value z'isi yose.

Muri rusange, valve z'irembo ntizikwiriye kugenga urujya n'uruza rw'amazi cyangwa gukora mu cyerekezo icyo ari cyo cyose kitari ugufungura cyangwa gufunga burundu. Gukoresha valve y'irembo idafunguye cyane kugira ngo uhunge cyangwa ugenzure urujya n'uruza rw'amazi bishobora kwangiza plate ya valve cyangwa impeta y'intebe ya valve, kuko mu gihe urujya n'uruza rw'amazi rudafunguye cyane rutera imvururu, ubuso bw'intebe ya valve buragongana.

Uburyo bwa valve y'irembo

Urebye inyuma, imvange nyinshi z'irembo zisa. Ariko, hari uburyo bwinshi butandukanye bwo gushushanya. Imvange nyinshi z'irembo zigizwe n'umubiri n'agapira, karimo ikintu cyo gufunga cyitwa disiki cyangwa irembo. Ikintu cyo gufunga gihuzwa n'igitereko kinyura muri kapira hanyuma kikagera ku gikoresho cyo gufunga cyangwa ikindi gitereko kugira ngo gikoreshe uruti. Igitutu kizenguruka agapira k'irembo kigenzurwa n'igitereko gishyirwa mu gice cyo gupakira cyangwa mu cyumba cyo gupakira.

Uburyo ikibaho cy’irembo cya valve kigenda kigenzura niba ikibaho cy’irembo kizamuka cyangwa kijya mu gice cy’irembo mu gihe cyo gufungura. Iki gikorwa kandi gisobanura ubwoko bubiri bw’ingenzi bwa stem/disk ku mavali y’irembo: ikibaho cy’irembo kizamuka cyangwa ikibaho kitazamuka (NRS). Ikibaho cy’irembo ni cyo gishushanyo mbonera cya stem/disk kizwi cyane ku isoko ry’inganda, mu gihe ikibaho cy’irembo kidazamuka kimaze igihe kinini gikundwa n’inganda zikora amazi n’imiyoboro y’amazi. Amwe mu mato akoresha amavali y’irembo kandi afite ahantu hato na yo akoresha uburyo bwa NRS.

Igishushanyo mbonera cy’inkingi/agasanduku k’ingoboka gikunze gukoreshwa ku mashini zikora imashini ni umugozi n’agasanduku k’ingoboka byo hanze (OS&Y). Igishushanyo mbonera cya OS&Y gikwiriye cyane ahantu hashobora kwangirika kuko imigozi iba iri hanze y’agace gafunga amazi. Gitandukanye n’ibindi bishushanyo kuko uruziga rw’ingoboka rufatanye n’agasanduku kari hejuru y’agasanduku, ntabwo rufatanye n’agasanduku ubwako, kugira ngo uruziga rw’ingoboka rudahaguruka iyo mashini ifunguye.

Igabanywa ry'isoko ry'ama-valve y'irembo

Nubwo mu myaka 50 ishize, valve zizunguruka zifite inguni y'iburyo zagize uruhare runini ku isoko ry'ingufu z'amarembo, zimwe mu nganda ziracyazishingiraho cyane, harimo n'inganda za peteroli na gaze. Nubwo valve z'umupira zateye imbere mu miyoboro ya gaze karemano, imashini zikoresha peteroli cyangwa amazi ziracyari ahantu hahurira valve z'ingufu z'amarembo zicaye hamwe.

Mu gihe cy’ingano nini, valve z’amarembo ziracyari amahitamo akomeye mu bikorwa byinshi mu nganda zitunganya. Ubuhanga bw’igishushanyo mbonera n’ikiguzi cyose cyo gutunga (harimo n’amafaranga yo kubungabunga) ni byo byifuzwa muri iki gishushanyo gakondo.

Mu bijyanye n'ikoreshwa, uburyo bwinshi bwo gutunganya ibikoresho bukoresha ubushyuhe buri hejuru y'ubushyuhe bwizewe bwa Teflon, ari na bwo buryo bw'ingenzi bwo kwicaraho hakoreshejwe valve z'umupira zigenda zirembera. Valve z'ibinyugunyugu zikora neza cyane hamwe na valve z'umupira zifunze ibyuma zitangiye gukoreshwa cyane mu gutunganya ibikoresho, nubwo ikiguzi cyazo cyose cyo gutunga akenshi kiba kiri hejuru y'icy'ibyuma by'amarembo.

Inganda z’amazi ziracyari zoganjemo amabati y’icyuma. Ndetse no mu bikorwa bitwikiriwe, arahendutse kandi araramba.

Ikoreshwa ry'inganda z'amashanyarazivalves z'irembo ry'icyumaku bikorwa birimo umuvuduko mwinshi cyane n'ubushyuhe bwinshi cyane. Nubwo hari vali nshya za Y-type globe na vali z'icyuma zicaye zagenewe kuziba zabonetse mu ruganda rw'amashanyarazi, vali z'amarembo ziracyakunzwe n'abashushanya uruganda n'abarukoresha.
