Okwegyendesereza omu kukozesa valve.

Omuringo gw’okukora valvu nagwo n’omuringo gw’okukyebera n’okukwata valvu. Kwonka enshonga ezi ahaifo ziine kuteebwaho omutima waaba nookora valve.

Valve y’obutagatsi bw’ahaiguru. Ebiriisa byaba biri ahaiguru ya 200°C, obukomooko nibuheebwa obutagatsi kandi buraingwa, eki kyorobi kureetera ekikwato ky’okukinga valve kusheesheka. Omu bwire obu, obukomooko nibwetenga “kuhamibwa omu muringo gw’okwotsya”, kandi tikihikire kukora okuhamibwa omu muringo gw’okwotsya omu mwanya ogukingire kimwe ogw’ekibunu, kugira ngu okwetantara ekiti ky’ekibunu kufa kandi kigumire kwigura bwanyima.

2Omu bwire obu obutagatsi buri ahansi ya 0°C, fayo kwigura ekikwato ky‘entebe ya valvu ahabwa valvu ezirikuremesa omuyaga n‘amaizi kwihaho amaizi agarimu obufuki n‘amaizi agarundaine, kugira ngu otafuka n‘okusharaho valvu. Fayo aha kurinda obutagatsi ahabw‘ebikwato ebitarikubaasa kwihaho okuteerana kw‘amaizi n‘ebikwato ebirikukora omu bwire bukye.

Ekikwato ky‘okupakira tikiine kunyigirizibwa munonga, kandi okukora okurikuhindukahinduka kw‘omutindo gwa valvu kushemerire kusingura (nikigwire kuteekateeka ngu ekikwato ky‘okupakira kyaguma nikihamibwa, nikwo kirikuba kirungi, nikiija kutunguura okujwara kw‘omutindo gwa valvu n‘okwongyera aha nkora y‘okukora). Omu mbeera y‘okubura oburinzi, okupakira tikurikubaasa kugarurwaho nari kwongyerwamu ahansi y‘okugyemeserezibwa.

4Omu bwire bw‘okukora, ebintu ebitari bya buriijo ebirikushangwa omu kuhurikiza, okunuuka, okureeba, okukora aha nshonga, n‘ebindi biine kukyeberwa gye ahabw‘enshonga, kandi ebyo ebiri omu nkora zaabo biine kwihwaho omu bwire;

Orikukoraho ashemerire kuba aine ekitabo ky’omutaano ky’okuhandiikaho nari ekitabo ky’okuhandiikaho, kandi agyende aha kuhandiika oku ebikwato bitari bimwe na bimwe birikukora, namunonga ebikwato ebimwe ebikuru, ebikwato by’obutagatsi bwingi n’eby’okuteerana n’ebikwato by’omutaano, otwariiremu n’ebikwato byabyo eby’okujanjaaza. Bashemerire kumanya okuremwa, okujanjaba, okugaruzaho ebicweka, n‘ebindi, ebintu ebi ni bikuru aha mukozi we wenka, abakozi abarikubiboneza n‘orikubikora. Taho orubazo rw‘omutaano orurimu obujunaanizibwa oburikworeka gye, ekirikugasira okuhamya entwaza.
