Hariho emiringo mingi y’ebizimba by’ebinyonyi, kandi hariho n’emiringo mingi y’okubishoroora.
1. Okushoroora kurugiirira aha nkora y‘enkora
(1)valvu y'ekihuguhugu eri ahagati; (2) valvu y’ebinyonyi erimu ekicweka kimwe; (3) emirundi ebiri-valvu y'ekihuguhugu etari emwe n'emwe; (4) valvu y’ebinyonyi eshatu ey’omutaano
2. Okushoroora kurugiirira aha kintu ekirikukingaho
(1) Valvu y'ekihuguhugu egumire
(2) Valve y’ekinyonyi egumire ey’omuringo gw’ekyoma. Ekipande ky’okukinga kirimu eby’ekyoma ebigumire kuhika aha by’ekyoma ebigumire.
3. Okushoroora kurugirira aha foomu ekingire
(1) Okugyemeserezibwa kukingaho valvu y’ebinyonyi.
(2) Valve y’ebinyonyi erikukingira pressure. Pureesha y‘okukinga neeruga omu kintu ky‘okukinga ekirimu elastic aha ntebe nari aha rupapura.
(3) Valve y’ebinyonyi erikwekingaho. Pressure y’omutaano ey’ekipande neeruga omu pressure y’ahagati.
4. Okushoroora kurugiirira aha kugyemeserezibwa kw’okukora
(1) Ekicweka ky’ekinyonyi ekirikureeta omuyaga. Valve y‘ebinyonyi erimu pressure y‘okukora eri ahansi y‘embeera y‘omu mwanya.
(2) Valvu y’ebinyonyi erimu amaani makye. Valvu y‘ebinyonyi erimu omuhimbo gw‘eiziina ogwa PN≤1.6MPa.
(3) Valvu y’ebinyonyi ey’omugati. Pureesha y‘eiziina PN ni valve y‘ebinyonyi eya 2.5∽6.4MPa.
(4) Valve y’ebinyonyi ey’amaani. Pureesha y’eiziina PN ni valve y’ebinyonyi eya 10.0∽80.OMPa.
(5) Valvu y’ebinyonyi ey’amaani munonga. Valvu y‘ebinyonyi erimu omuhimbo gw‘eiziina PN <100MPa.
5. Okushoroora kurugirira aha muringo gw’okukwatiraine
(1)Valuvu y'ekihuguhugu
(2) Ekihuguhugu kya flange
(3) Lug ekihuguhugu valvu
(4) Valvu y’ebinyonyi eshemeire
Concentric Butterfly valve n’omuringo gwa valve erikwigura n’okukinga n’empapura z’ebinyonyi ezirikwetoorora kandi ekingura, ekingaho kandi ekahindura omuhanda gw’amaizi n’okuhinduka kw’omuti gwa valve. Empapura z’ekinyonyi z’ekinyonyi z’ekinyonyi niziteebwa omu rubaju rwa diamita y’omupiira. Omu muhanda gw’ekibunu ky’omubiri gw’ekinyonyi ky’ekinyonyi, ekipande ky’ekinyonyi ky’ekinyonyi ekya disiki nikyetoorora ekibunu, kandi Enkokora y’okwetoorora eri ahagati ya 0 na 90. Okwetoorora kwaba nikuhika ahari 90, ekinyonyi nikiba kikingire kimwe.
Enshonga nkuru z‘okwombeka n‘okutaho
1) Omwanya gw’okutaho, oburaingwa, omuhanda gw’okureeta n’okushohoza biine kuhikiiriza ebirikwetengyesa omu kuteekateeka, kandi okuteerana kushemerire kuba kuhamire kandi kuhamire.
2) Omukono gw’emiringo yoona ey’ebikwato by’omu ngaro ebiteirwe aha payipu y’okuzibira obutagatsi tigushemerire kuba guri ahansi.
3) Valve eine kukyeberwa aheeru etakateirweho, kandi empapura z’eiziina rya valve ziine kuhikiiriza ebiragiro by’omutindo gw’eihanga oguriho hati “General Valve Mark” GB 12220. Aha valve eziine pressure y’okukora erikurenga 1.0 MPa n’okusharaho aha payipu enkuru zitakateirwemu, amaani n’okukora gye shalld be be abahikire. Omu kugyezibwa kw‘amaani, omuhimbo gw‘okugyezibwa nigukira emirundi 1.5 y‘omuhimbo gw‘eiziina, kandi obwire tiburi ahansi y‘edakiika 5. Ekibunu kya valve n’okupakira biine kuba bihikire hatariho kusheeshasheesha. Aha kugyezibwa kw’okuhamya, okugyezibwa kwa pressure ni emirundi 1.1 ahari pressure y’eiziina; pressure y‘okugyezesa neija kuhikiiriza omutindo gwa GB 50243 kumara obwire bw‘okugyezesa, kandi aha mutwe gw‘ekikingirizo kya valve niguba guhikire.
Okutoorana ebintu aha nshonga nkuru
1. Ebintu ebikuru ebirikutegyeka valve y’ekinyonyi n’ebirikworeka n’ebipimo.
2. Valve y’ekinyonyi n’ekikwato ky’omuyaga eky’empapura emwe, omubumbi gwayo gworobi, okukora gye, omuhendo mukye, okukora kwanguhi, kwonka okuhindura okuhikire ni kubi, nikuhikaana n’okutaho omuyaga n’okukyendeeza omuyaga gwonka ahabw’okuhindura nari okuhindura kw’omukoro omu muringo gw’obushaarizi.
3. Nikibaasa kuba eky’omu ngaro, eky’amashanyarazi nari eky’omuringo gwa zipu, nikibaasa kuhamibwa aha Angle yoona eya 90 range.
4. Ahabw’ekipande ky’ekikwato kimwe eky’omutindo gumwe, amaani g’okutwara nigakye, omu mbeera y’entaaniso mpango ya pressure, omubaro gw’okusheesheka kwingi obu amagara g’obuheereza bwa valve garikuba makye. Valve eine ekika ekikingire n’ekika kya buriijo, ekirikuzibira n’ekitarikuzibira.
5. Valve y’ebinyonyi ey’amashanyarazi eine okutegyeka kw’emiringo ebiri yonka, actuator y’amashanyarazi neeshushana na valve y’amababi maingi.
