Valvu z’ebinyonyi nizikora zita?

Valvu y'ekihuguhuguni ekika kya valve erikukoresa ekicweka ky‘okukingura n‘okukinga disiki kugarukamu nk‘ebicweka 90° kwigura, kukinga nari kuhindura omubaro gw‘okusheeshasheesha kw‘omugati. Butterfly valve teine ​​nkora eyorobi yonka, obuhango bukye, oburemeezi bukye, okukoresa ebintu bikye, obuhango bukye bw’okutaho, torque nkye y’okuvuga, okukora kwanguhi kandi okwa juba, kwonka kandi eine n’omurimo murungi gw’okutegyeka okusheesheka n’emitwarize y’okukinga, kandi n’emwe aha miringo ya valve erikukura juba omu myaka ikumi ehweire. Valvu z’ebinyonyi nizikoresibwa munonga. Omuringo n’omuhendo gw’okugikozesa nibigumizamu nibyeyongyera, kandi nibitunguuka kuhika aha bwire bw’obutagatsi bwingi, okugyemeserezibwa kwingi, oburaingwa bwingi, okuhamibwa kwingi, amagara maingi, emitwarize mirungi y’okutegyeka, n’okukora ebintu bingi eby’ekicweka kimwe. Okwesigwa kwayo n’ebindi ebirikworeka okukora kwayo bihikire aha rurengo rwahaiguru.

N’okukoresa emipiira y’obuhangwa etarikubaasa kukwatwa emibazi kuhika ahaza valvu z'ekihuguhugu, okukora kwa .za valvu z'ekihuguhugukitunguukire. Ahabw‘okugira ngu emipiira y‘obuhangwa eine emitwarize y‘okuzibira okusheenya, okuzibira okusheenya, okuguma omu bipimo, okugumisiriza kurungi, okukora kwanguhi, omuhendo mukye, n‘ebindi, emipiira y‘obuhangwa erimu emitwarize etari emwe n‘emwe neebaasa kutooranwa kurugiirira aha byetengo by‘okukoresa ebitarikushushana kuhikiiriza embeera z‘okukora eza .za valvu z'ekihuguhugu.

Ahabw’okugira ngu polytetrafluoroethylene (PTFE) eine amaani g’okuzibira okusheeshasheesha, okukora okuhamire, tikwanguha kukura, omubaro mukye gw’okuteerana, kworoba kuhanga, okuhama kw’ebicweka, kandi neebaasa kutunguura emitwarize yaayo yoona orikwijuza n’okwongyeraho ebintu ebihikire, ekinyonyi ky’okukingaho ekinyonyi ekiine obugarukiro n’ekintu ekiine obugarukiro nikibaasa kuba okuteerana. y’emipiira y’obuhangwa nizisingurwa, n’ahabw’ekyo ekintu kya polymer polymeric ekirikujwekyerwa PTFE n’ebintu byakyo ebihindwirwemu ebirikwijuza bikoresiibwe munonga omu nkora y’okuteera ebinyonyi, n’ahabw’ekyo okukora kw’enkora y’okuteera ebinyonyi kwongyeire kutunguuka.Valvu z'ekihuguhugun’embeera z’obutagatsi n’okugyemeserezibwa kwingi, okukora kw’okukinga okurikwesigwa n’okumara obwire buraingwa omu kuheereza bikozirwe.

Okubaasa kuhikiiriza ebyetaago by’okukoresa omu makorero nk’obutagatsi bw’ahaiguru n’obw’ahansi, okusheenya kw’amaani, n’okumara obwire buraingwa, ebikwato by’okukingaho eby’ekyoma eby’ebinyonyi bikozirwe munonga. N‘okukozesa okuzibira obutagatsi bw‘ahaiguru, okuzibira obutagatsi bukye, okuzibira okusheenya kw‘amaani, okuzibira okusheenya kw‘amaani, n‘ebintu by‘amaani maingi eby‘ekyoma omu bicupuri by‘ebinyonyi, ebicupuri by‘ebinyonyi ebikingirwe eby‘ekyoma bikoresiibwe munonga omu mirimo y‘amakorero nk‘ebicupuri by‘ahaiguru n‘eby‘ahansi, ebicupuri by‘amaani by‘okusheeshasheesha, n‘amagara maingi g‘ebinyonyi dia9 mm, n‘amagara maingi g‘ebinyonyi. pressure (42.0MPa) n’obutagatsi bwingi (-196~606°C) byareebeka, n’ahabw’ekyo tekinologiya y’ebicupuri by’ebinyonyi ehikire aha rurengo rusya.

Valve y’ebinyonyi ku erikwigurwa omu bwijwire, neeba eine obuzibu bukye bw’okusheesheka. Okwigura kwaba kuri ahagati ya 15°~70°, nikubaasa kukoresibwa omu kuhabura okugyendera kw’amaizi okurikwetegyerezibwa, n’ahabw’ekyo okukoresa butterfly valve nikukira kubaho munonga omu murimo gw’okuhindura ebiri omu nkora mpango.

Ahabw‘okutambura okurikubaasa kusiimura kw‘ekipande ky‘ebinyonyi ky‘ekinyonyi ky‘ekinyonyi, ebinyonyi ebingi nibibaasa kukoresibwa omu by‘amakuru ebiine ebigumire ebihanikire. Okurugirira aha maani g’ekipande, nikibaasa n’okukoresibwa omu bihandiiko by’obutunguru n’eby’obujuma.

Valvu z’ebinyonyi nizikora gye omu kuhabura okutambura kw’amaizi. Ahabw‘okugira ngu okufeerwa kw‘amaani g‘ekinyonyi ky‘ekinyonyi omu payipu ni kwingi munonga, nk‘emirundi eshatu y‘ekikopo ky‘omuryango, waaba nootoorana ekinyonyi ky‘ekinyonyi, okufeerwa kw‘amaani kw‘enkora y‘ekinyonyi kushemerire kuteekateekwaho omu bwijwire, kandi amaani g‘ekipande ky‘ekinyonyi okwekorera amaani g‘ekinyonyi ky‘omu payipu gaine kuteekateekwaho n‘obu kirikukingwaho. Okwongyera ahari ekyo, obugarukiro bw‘obutagatsi bw‘okukora obu ekintu ky‘entebe y‘elastomeric kirikubaasa kuteebwaho aha bwire bw‘obutagatsi bw‘ahaiguru nabwo bwine kuteekateekwaho.

Valve y‘ebinyonyi eine oburaingwa bukye bw‘okwombeka n‘oburaingwa bwona, okukinga n‘okukinga juba, n‘emitwarize mirungi y‘okutegyeka amaizi. Omusingye gw’obuhangwa bw’ebicupuri by’ebinyonyi nigwo gurikukirayo kuhikaana n’okukora ebicupuri by’ebicupuri ebihango. Ku kiraabe nikyetengyesa kukoresa ekikwato ky‘okusheeshasheesha okutegyeka okusheesheka kw‘amaizi, ni kikuru kutoorana obuhango n‘omuringo gw‘ekikwato ky‘okusheeshasheesha ekihikire kugira ngu kikore gye kandi kikore gye.

Okutwarira hamwe, omu kukyebera, okutegyeka n‘omugati gw‘ebishaka, oburaingwa bw‘omutindo nibukye, omuvuyo gw‘okukinga n‘okukinga nigurahuka, kandi okusharaho kwa pressure nkye (entaaniso nkye ya pressure) nikyetengyesa, kandi butterfly valve neehaburwa. Valvu z‘ebinyonyi nizibaasa kukoresibwa haaba hariho okuhindura omu myanya ebiri, omuhanda gw‘okukyendeeza aha diamita, okuteera akaari kakye, okusheeshasheesha n‘okusheeshasheesha, okusheeshasheesha okukye omu mwanya, n‘ebintu ebirikusheenya. Omu mbeera z‘omutaano z‘okukora, okuhindura omu throttling, nari okukingaho okugumire, okujwara munonga, obutagatsi bukye (cryogenic) n‘embeera ezindi z‘okukora.
