1. Valve y'irembo ni iki?
Valve y'irembo ni valve ikoreshwa mu GUFUNGURA no GUZIMA urujya n'uruza rw'amazi mu muyoboro. Ifungura cyangwa igafunga valve izamura irembo kugira ngo yemerere cyangwa ihagarike urujya n'uruza rw'amazi. Byakagombye gushimangirwa ko valve y'irembo idashobora gukoreshwa mu kugenzura urujya n'uruza rw'amazi, ahubwo ikwiriye gusa gukoreshwa mu gusaba urujya n'uruza rwuzuye cyangwa gufunga burundu.
Uburyo bwo gushyiramo imvange y'irembo: GB/DIN/API/ASME/GOST.

2. Imiterere ya Valve y'Irembo
Amavali yo mu irembo ubusanzwe agizwe n'ibice byinshi by'ingenzi:
1) Igice cy'ingenzi cya valve: Igice cy'ingenzi cyane cya valve y'irembo. Ibikoresho bikunze gukorwa mu byuma bito, WCB, SS, nibindi.
2) Irembo: igice cyo kugenzura, gishobora kuba isahani ipfutseho rubber cyangwa isahani y'icyuma gikozwe mu buryo bwa gakondo.
3) Uduti twa valve: twakoreshejwe mu kuzamura irembo, dukozwe muri F6A (ibumba rya ss 420), Inconel600.
4) Bonnet: igikonoshwa kiri hejuru y'umubiri wa valve, hamwe n'umubiri wa valve bigakora igikonoshwa cyuzuye cya valve.
5) Intebe ya vali: ubuso bwo gufunga aho icyapa cy'irembo gihurira n'umubiri wa vali.
3. Ubwoko butandukanye bwa Valuve zo mu Gati ni ubuhe?
Dukurikije ubwoko bw'imiterere y'umuzingo w'imvange, ishobora kugabanywamo valve idakomeza kuzamuka n'valve idakomeza kuzamuka.
1)Valve y'irembo idazamuka:Igice cyo hejuru cy'agace k'imvange y'imvange y'imvange y'imvange ihishe ntigikwirakwira hamwe n'uruziga rw'intoki. Agace k'imvange kazamuka cyangwa kamanuka ku gace k'imvange kugira ngo gafungure cyangwa gafunge agace k'imvange. Agace k'imvange y'imvange y'imvange yose y'imvange ni ko gafite aho kajya.
2)Valve y'irembo ry'umugongo iri kuzamuka (valve y'irembo ya OS&Y):Igice cyo hejuru cy'agasanduku k'irembo ry'umugongo kizamuka kiba kiri hejuru y'uruziga rw'amaboko. Iyo agasanduku k'irembo gafunguwe cyangwa gafunze, agasanduku k'irembo n'icyuma cy'irembo birazamurwa cyangwa bigamanurwa hamwe.
4. Valve y'irembo ikora ite?
Imikorere ya valve y'irembo iroroshye cyane kandi ikubiyemo intambwe zikurikira:
1) Imbere y'uko ifunguye: Iyo valve y'irembo iri mu mwanya ufunguye, icyuma cy'irembo kirazamurwa burundu kandi amazi ashobora gutembera neza mu muyoboro w'umubiri wa valve.
2) Imiterere y'aho ifunze: Iyo valve ikeneye gufungwa, irembo rishyirwa hasi. Rishyirwa ku ntebe ya valve kandi rigakorana n'ubuso bufunga umubiri wa valve, bigatuma amazi adasohoka.
5. Valve y'irembo ikoreshwa iki?
Amavali yo mu irembo afite uburyo bwinshi kandi ashobora gukoreshwa mu nganda zitandukanye n'ibidukikije, nko:
1) Gutunganya amazi: Utwuma tworoshye two gufunga ni two dukoreshwa cyane mu gutunganya amazi n'amazi yanduye.
2) Inganda za peteroli na gaze karemano: Valves zifunga neza zikoreshwa mu nganda za peteroli na gaze karemano.
3) Gutunganya imiti: Amasafuriya yo mu cyuma kidashonga akwiriye kugenzura urujya n'uruza rw'imiti n'ibintu byangiza mu gutunganya imiti.
4) Sisitemu za HVAC: Vali zo mu irembo zikoreshwa mu buryo bwo gushyushya, guhumeka no gukonjesha (HVAC).
None se, ese ama-valves y'irembo ashobora gukoreshwa mu gufunga?
Nkuko bigaragara muri ibi byavuzwe haruguru, igisubizo ni OYA! Intego y'ibanze ya valve y'irembo ni ugufungura neza no gufunga neza. Iyo ikoreshejwe ku ngufu mu guhindura amazi, amazi anyura nabi, umuyaga n'ibindi bintu bizabaho, kandi bizatera gucika intege no kwangirika byoroshye.
6. Ibyiza bya Valve y'Irembo
1) Inzira yuzuye: Iyo ifunguye neza, irembo riba ringana n'iry'imbere ry'umuyoboro, bigatuma amazi atembera neza kandi umuvuduko ugabanuka cyane.
2) 0 Gusohoka: Iyo icyuma gifunga icyuma gihuye n'intebe y'icyuma, hashyirwaho agafunga gakomeye kugira ngo amazi adasohoka muri icyuma. Ubuso bufunga icyuma n'intebe y'icyuma bikunze gukorwa mu bikoresho nk'icyuma cyangwa elastomer kugira ngo amazi afungwe kandi umwuka ufungwe nta gusohoka.
3) Gufunga inzira ebyiri: Amavali yo ku irembo ashobora gutanga uburyo bwo gufunga inzira ebyiri, bigatuma akoreshwa mu miyoboro ifite uburyo bwo gusubira inyuma.
4) Gusana byoroshye: Nta mpamvu yo gusenya valve y'irembo burundu. Ugomba gufungura igipfundikizo cya valve gusa kugira ngo imiterere y'imbere igaragare neza kugira ngo ikomeze gusanwa.
7. Ingaruka mbi z'amavaluve yo mu marembo
1) Ugereranyije n'izindi valve zifite imiterere yoroshye (nk'ibyuma), umubiri wa valve ukoresha ibikoresho byinshi kandi igiciro kiri hejuru.
2) Ubugari ntarengwa bwa valve y'irembo bugomba kuba buto, muri rusange DN≤1600. Valve y'ikinyugunyugu ishobora kugera kuri DN3000.
3) Valve y'irembo ifata igihe kirekire kugira ngo ifunguke kandi ifungwe. Iyo ikeneye gufungurwa vuba, ishobora gukoreshwa hamwe n'icyuma gikoresha umwuka.
