Omusingye gw'okukora hamwe n'okwombeka hamwe n'okutaho emyanya ya valvu y'ebinyonyi erimu emipiira

Evalvu y'ebihugu eshutami omu rubaahoni ekika kya valvu ekirikukoresa ekipande ky‘ekinyonyi ekizingire nk‘ekicweka ky‘okukinga n‘okukinga kandi kikyetoorora n‘omuti gwa valvu kwigura, kukinga n‘okuhindura omuhanda gw‘amaizi. Eshahani y’ebinyonyi ey’omu .valvu y'ebihugu eshutami omu rubaahoniziteebwa omu rubaju rwa diamita y’omupiira. Omu muhanda gw’ekibumbe ky’omubiri .valvu y'ebihugu eshutami omu rubaahoomubiri, ekipande ky’ebinyonyi ekiine omubiri nk’ogwa disiki nikyetoorora ekibunu, kandi enkokora y’okwetoorora eri ahagati ya 0° na 90°. Ku erikwehindura kuhika ahari 90°, valve neeba eigukire kimwe.

Emyanya y'okwombeka n'okutaho

1. Omwanya gw’okutaho, oburaingwa, n’orubaju rw’okureeta n’okushohoza biine kuhikiiriza ebirikwetengyesa omu kuteekateeka, kandi okuteerana kushemerire kuba kuhamire kandi kuhamire.

2. Aha miringo yoona ey’ebikwato by’okukoresa omu ngaro ebiteirwe aha nshaho y’okuzibira obutagatsi, omukono tigushemerire kuba guri ahansi.

3. Okukyebera okurikureebwa kushemerire kukorwa valvu etakateirweho, kandi ekipande ky’eiziina rya valvu kiine kuhikiiriza ebirikwetengyesa omu mutindo gw’eihanga oguriho hati “General Valve Mark” GB12220. Aha valve erimu pressure y’okukora eri ahaiguru ya 1.0MPa kandi erikukora omurimo omu kusharaho omupiira omukuru, okugyezibwa kw’amaani n’okukora okuhamire kushemerire kukorwa etakateirwemu, kandi neekirizibwa kukoresibwa bwanyima y’okuhingura omu kugyezibwa. Omu bwire bw‘okugyezibwa kw‘amaani, okugyezibwa kw‘amaani nikukira emirundi 1.5 y‘okugyezibwa kw‘eiziina, kandi obwire tiburi ahansi y‘edakiika 5. Enju ya valve n’okupakira biine kuba bihikire hatariho kusheeshasheesha. Omu kugyezibwa kw’okuhamya, omuhimbo gw’okugyezibwa nigukira emirundi 1.1 omuhimbo gw’eiziina; pressure y‘okugyezesa eshemerire kuhikiiriza ebyetaago bya GB50243 standard omu bwire bw‘okugyezesa, kandi aha mutwe gw‘okukinga valve disc niguba guhikire haaba hatariho kusheeshasheesha.

Enshonga z'okutooranamu ebintu

1. Ebikuru ebirikutegyeka ebirikukwata ahavalvu y'ebihugu eshutami omu rubaahonizo nshonga n’ebipimo.

2. Nikibaasa kukoresibwa omu ngaro, amashanyarazi nari zipu, kandi nikibaasa kuhamibwa omu rubaju rwona oruri omu 90°.

3. Ahabw’okugira ngu shafu emwe n’empapura za valve emwe, obushoboorozi bw’okutwara nibukye, kandi obwire bw’obuheereza bwa valve nibukye ahansi y’embeera z’entaaniso mpango ya pressure n’omubaro muhango gw’okusheesheka.
