Okugaaniira aha kumanya kwa valve y'ebinyonyi

Omu myaka ya 30, abavalvu y'ekihuguhugukikahangwa omuri America, kyatandikwa omuri Japan omu myaka ya 50, kandi kyakoresibwa munonga omuri Japan omu myaka ya 60, kandi kyatunguuka omuri China bwanyima y’emyaka ya 70. Obwahati, ebikwato by’ebinyonyi ebiri ahaiguru ya DN300 mm omunsi yoona bibaire nibihindura mporampora ebikwato by’omuryango. Kugyeragyeranisa naza valvu z'omuryango, butterfly valves ziine obwire bukye bw’okukinga n’okukinga, torque y’okukora nkye, omwanya mukye gw’okutaho n’oburemeezi bukye. Twatwara DN1000 nk’eky’okureeberaho, valve y’ekinyonyi neehika nka 2T, kandi valve y’omuryango eri nka 3.5T, kandi valve y’ebinyonyi n’eyanguhi kugaita n’ebintu bitari bimwe na bimwe eby’okuvuga, n’okugumaho kurungi n’okwesigwa.

Obubi bw'ekipande ky'orubaarevalvu y'ekihuguhuguni ngu ku erikukoresibwa omu kusheenya, okusheenya nikwija kubaho ahabw’okugikoresa kubi, ekirikureetera entebe y’orubaare kusheenya kandi ekashiisha. Omu myaka ehweire, China nayo ekozire ebikwato by’okukinga ebinyonyi ebikingirwe eby’ekyoma, kandi omu myaka ehweire, Japan nayo ekozire ebikwato by’ebinyonyi ebiine omubiri nk’ekishumuruzo ebiine obuzibu bw’okusheenya, okutengeeta okukye n’okuteera orwaari rukye.

Amagara g‘okukoresa entebe y‘okukinga omu bwijwire n‘emyaka 15-20 aha mipiira n‘emyaka 80-90 aha kyoma omu mbeera eza butoosha. Kwonka oku orikubaasa kutoorana gye nikirugiirira aha byetengo by’embeera z’okukora.

Enkoragana eri ahagati y’okukingura .valvu y'ekihuguhugukandi omubaro gw‘okusheesheka omu kubanza nigushushana n‘omutindo kandi niguhikaana. Ku kiraabe nikikoresibwa kutegyeka omubaro gw’okusheesheka, emitwarize yaayo y’okusheesheka nayo neekwatagana munonga n’okuzibira okusheesheka kw’emipiira, nk’oburaingwa n’omuringo gw’ebipimo ebiteirwe omu mipiira ebiri nibishushana, kandi omubaro gw’okufeerwa kw’emipiira nigutaana, kandi omubaro gw’okusheesheka kw’emipiira nigwija kuba nigutaana munonga.

Valve yaaba eri omu mbeera y’okuteera munonga, enyima y’ekipande kya valve neebaasa kusheenya, kandi hariho okubaasa kw’okushiisha valve, n’ahabw’ekyo okutwarira hamwe neekoresibwa aheeru ya 15°.

Ekinyonyi ky’ekinyonyi kyaba kiri omu kiina kya rwagati, ekishushani ky’ekiina ekirikukorwaho .valvuomubiri n’omuheru gw’omu maisho gw’ekipande ky’ekinyonyi kiri ahagati y’ekipande ky’ekinyonyi, kandi embaju ibiri nizikora embeera zitari zimwe na zimwe, omuheru gw’omu maisho gw’ekipande ky’ekinyonyi aha rubaju rumwe nigutambura omu rubaju oru amaizi garikugyenderamu, kandi orubaju orundi nirugyendera aha rubaju oru amaizi garikugyenderamu, n’ahabw’ekyo, omubiri gw’ekipande ky’ekinyonyi nigukora aha rubaju rumwe n’orubaju orundi, n’orubaju orundi. nikishushana n’ekiina ky’okukingaho ekiine omubiri nk’ekiina ky’okuteera, orubaju rw’entuura nirurahuka munonga kukira orubaju rw’okuteera, kandi omuhimbo mubi nigwija kuruga ahansi y’ekipande ky’orubaju rw’okuteera, kandi ekikwato ky’okuteera orupiira nikikira kugwa.

Torque y’okukora ya butterfly valve, ahabw’okutaana kw’okukingura n’okukingura orubaju rwa valve, omuhendo gwayo nigutaana, kandi butterfly valve eri omu rubaju, namunonga valve y’oburaingwa bwingi, ahabw’oburaingwa bw’amaizi, torque erikuruga omu ntaaniso eri ahagati y’omutwe gwa ruguru n’ogwa hansi gw’ekibunu tigurikubaasa kugaya. Okwongyera ahari ekyo, ekikumu kyateebwa aha rubaju orurikutaaha omu valve, nihabaho omuvuyo gw’okuhinduka (deflection flow), kandi torque neeyeyongyera. Valve ku erikuba eri omu kwigura kwa rwagati, omuringo gw’okukora nigwetenga kwekingaho ahabw’ekikorwa ky’omuvuyo gw’amaizi.
