Valvu y'omuryango navalvu y'ekihuguhugu byombi nibikora omurimo gw‘okuhindura n‘okutebeekanisa okutambura omu kukoresa emipiira. N’amazima, hakiriho omuringo omu kutoorana obutafaari bw’ebinyonyi n’obutafaari bw’omuryango. Okubaasa kukyendeeza oburaingwa bw’okukingaho eitaka ry’omupiira omu nkora y’okuha amaizi, okutwarira hamwe emipiira y’oburaingwa bw’amaani neeba erimu ebikwato by’okukingiraho ebinyonyi, ebiine akakwate kakye n’oburaingwa bw’okukingira eitaka, kandi nibiteeraho kutoorana ebikwato by’omuryango.
Ni ntaaniso ki eri ahagati y’ekinyonyi ky’ebinyonyi n’ekikopo ky’omuryango?
Okurugirira aha murimo n‘okukozesa gate valve na butterfly valve, gate valve eine obuzibu bukye bw‘okusheeshasheesha n‘okukora gye omu kukinga. Ahabw‘okugira ngu orubaju rw‘okusheesheka kw‘empapura z‘okukingiraho n‘ekikwato ky‘ahagati biri aha rubaju orurikutegyeka, ekipande ky‘omuryango kyaba kitahindukire omu mwanya gwakyo aha mpapura z‘okukinga, okusheenya kw‘ekipande ky‘okukinga nikwija kureetera empapura z‘okukinga kutengeeta. , Kyanguhi kushiisha ekishumuruzo ky’ekipande ky’omuryango. Valvu y’ekinyonyi, kandi emanyirwe nka flap valve, n’omuringo gw’okutegyeka ebiri omu nkora eyorobi. Valve y‘ebinyonyi erikubaasa kukoresibwa omu kuhabura aha on-off omu nkora y‘okukingaho emipiira y‘omutindo mukye nikimanyisa ngu ekicweka ky‘okukinga (disiki nari butterfly plate) ni disiki, erikwetoorora ekicweka kya valve kubaasa kuhikiiriza okukinga n‘okukinga. Valve erikubaasa kukoresibwa okutegyeka okutambura kw’ebintu by’emiringo etari emwe n’emwe nk’omuyaga, amaizi, omuyaga, ebintu bitari bimwe na bimwe ebirikushiisha, ebishaka, amajuta, ebyoma by’amaizi n’ebintu ebirikukora nk’eby’okurya. Okukira munonga nikikora omurimo gw’okushara n’okukyendeeza aha nshaho. Ekicweka ky’okukinga n’okukinga valvu y’ekinyonyi n’ekipande ky’ekinyonyi ekiine omubiri gw’ekinyonyi, ekirikwetoorora ekicweka kyakyo omu mubiri gwa valvu kuhikiiriza ekigyendererwa ky’okukinga n’okukinga nari okuhindura. Empapura z’ebinyonyi nizivugwa omuti gwa valve. Ku kiraabe kyahikize emyaka 90 .°, nikibaasa kuhezaho okukinga n’okukinga kimwe. Omu kuhindura enkokora y’okuhindura (deflection angle) ya disiki, okutambura kw’omugati nikubaasa kutegyekwa.
Embeera z‘okukora n‘omugati: Butterfly valve neebaasa kutwara amaizi gatari gamwe na gamwe agarikusheenya n‘agatarikusheenya omu nkora za inginiya nk‘omuhi w‘obuhwezi, gaasi y‘amakara, gaasi y‘obuhangwa, gaasi y‘amajuta g‘amaizi, gaasi y‘omu rurembo, empeho erikwotsya n‘erikwotsya, okusheenya emibazi n‘okukora amashanyarazi okurinda eby‘obuhangwa, the builline and etc. medium, nikikoresibwa kuhindura n’okusharaho okutambura kw’omugati.
Valve y’omuryango eine omuryango gw’ekicweka ogurikwigura n’okukinga, orubaju rw’okutambura kw’omuryango niruhikaana n’orubaju oru amaizi garikuza, kandi valvu y’omuryango neebaasa kwigura n’okukinga omu bwijwire yonka. Okutunguura okukora kwayo .or obushoboorozi n‘okukora aha kuhabisa kw‘enkokora y‘ahaiguru y‘okukinga omu bwire bw‘okukora, omuryango ogu nigwetwa omuryango gw‘okukinga.
Valve y’omuryango ku erikuba ekingire, eitaka ry’okukingaho niribaasa kwesiga pressure y’ahagati yonka kukingaho, nikwo kugira ngu, okwesiga pressure y’ahagati yonka kunyiganyiga eitaka ry’okukingaho ry’omuryango kuhika aha ntebe ya valve aha rubaju orundi kureeba ngu eitaka ry’okukingaho ryakingaho, erikwekingaho. Valvu z‘omuryango ezirikukira obwingi nizikingwa n‘amaani, nikwo kugira ngu, valvu ku erikuba ekingire, omuryango guteekwa kugyemeserezibwa aha ntebe y‘emuryango ahabw‘amaani g‘aheeru kureeba ngu aha mutwe gw‘ekikingirizo gwaguma guhamire.
Omuringo gw’okugyenderamu: Omuryango gw’ekiina ky’omuryango nigugyendera omu murongooti oguhikire n’omuti gw’ekiina, ekindi ekirikwetwa .OS&Y valvu y'omuryango. Obwire obwingi, aha nkoni y’okusimura nihaba hariho obuhuta bw’omuringo gwa trapezoidal. Kurabira omu nshaho eri aha mutwe gwa valve n’omuhanda gw’okuhabura aha mubiri gwa valve, omuvuyo gw’okuzinduka niguhindurwa guhinduka omuvuyo gw’omuringo gumwe, nikwo kugira ngu, torque y’okukora neehindurwa kuba omuvuyo gw’okukora. Valve ku erikwigurwa, oburaingwa bw‘okusimura omuryango bwaba buringana n‘emirundi 1:1 y‘oburaingwa bwa valve, omuhanda gw‘amaizi niguba gutaine ki gurikuzibira kimwe, kwonka omwanya ogu tigurikubaasa kukyeberwa omu bwire bw‘okukora. Omu kukozesa okwabuzima, enshonga y‘ahaiguru y‘ekiti kya valve neekoresibwa nk‘akamanyiso, nikwo kugira ngu, omwanya ogu etarikubaasa kwigurwamu, nk‘omwanya gwayo ogukingirwe omu bwijwire. Okubaasa kuteekateeka aha nkora y‘okukinga ahabw‘empindahinduka z‘obutagatsi, nikikira kwigurwa omu mwanya gw‘ahaiguru, reero kigarukye omu 1/2-1 turn, nk‘omwanya gw‘okukinga omu bwijwire. Nahabwekyo, omwanya gw‘okukingaho omu bwijwire ogwa valve nigumanyirwa aha mwanya gw‘omuryango (nikwo kugira ngu stroke). Ebimwe aha bihimba by’omuti gwa valve y’omuryango nibiteebwa aha geeti, kandi okwetoorora kw’enziga y’omu ngaro nikureetera omuti gwa valve kwetoorora, ekirikureetera omuryango kwimuka. Omuringo gw’ekikwato eki nigwetwa ekikwato ky’omuryango gw’omuti ogurikwetwa Rotary stem gate nari .NRS valvu y'omuryango.
