Kodi Pali Kusiyana Pati Pakati pa Triple Eccentric Butterfly Valve, Double Eccentric Butterfly Valve, Single Eccentric Butterfly Valve Ndi Centerline Butterfly Valve

Mavavu agulugufe wapakati, valavu yagulugufe wamtundu umodzi, valavu yagulugufe wamitundu iwiri komanso valavu yagulugufe katatu, mitundu iyi ya agulugufe amasintha malo osindikizira ndi kutsegulira poyika malo a shaft mbale.

Pazifukwa zomwezo, mbali yozungulira yofunikira kuti mbale ya valve ichotsedwe ku chisindikizo pamene valavu imatsegulidwa ndi yaying'ono kusiyana ndi ina, ndipo valavu imayendetsedwa ndi torque yaikulu kuposa ina pa kutsegula kulikonse.

Valve yagulugufe wamtundu wachitatu:

Pofuna kukana kutentha kwakukulu, chisindikizo cholimba chiyenera kugwiritsidwa ntchito, koma kuchuluka kwa kutayikira ndi kwakukulu;pa kutayikira kwa zero, chisindikizo chofewa chiyenera kugwiritsidwa ntchito, koma sichimalimbana ndi kutentha kwakukulu.Pofuna kuthana ndi kusagwirizana kwa valavu ya gulugufe wapawiri, valavu ya gulugufeyo inali yachitatu.Otchedwa wachitatu mtima ndi mawonekedwe a kusindikiza awiri si zabwino chulucho, koma khonde lopendekeka.Chinthu chapadera cha valavu ya butterfly ya katatu ndi chakuti valavu yomwe gulugufe amayikapo ndi gawo la magawo atatu.Zigawo ziwiri za shaft ya tsinde la valve ya shaft ya magawo atatu ndizokhazikika, ndipo mzere wapakati wa shaft wapakati umachotsedwa kuchokera kumalekezero awiri a axis ndi mtunda wapakati.Mbaleyi imayikidwa pachigawo chapakati cha shaft.Kapangidwe kameneka kamene kamapangitsa kuti diskiyo ikhale yapawiri pamene diski imatsegulidwa kwathunthu, ndipo imakhala imodzi yokha pamene diski imayendetsedwa kumalo otsekedwa.Chifukwa cha zochita za shaft eccentric, ikayandikira kutseka, imasuntha mtunda kupita kumalo osindikizira a mpando wa valve, ndipo mbale ya butterfly imagwirizana ndi kusindikiza pamwamba pa mpando wa valve kuti akwaniritse kusindikiza kodalirika.

Valovu yagulugufe wapawiri:

Kutengera valavu imodzi yokha yagulugufe, ndiye valavu yomwe imagwiritsidwa ntchito kwambiri pawiri.Zomwe zimapangidwira ndikuti shaft pakati pa tsinde la valve imachoka pakati pa diski ndi pakati pa thupi la valve.Zotsatira za eccentricity yawiri zimapangitsa kuti diski ikhale yolekanitsidwa mofulumira ndi mpando wa valve pambuyo pa kutsegulidwa kwa valve, zomwe zimachotsa kwambiri zosafunikira zowonjezera ndi kukanda pakati pa diski ndi mpando wa valve, zimachepetsa kukana kutsegula, kuchepetsa kuvala, ndi kukonzanso valavu. moyo wapampando wakuchita.

Valovu yagulugufe imodzi yokha:

Pofuna kuthetsa vuto la extrusion pakati pa diski ndi mpando wa valve wa valavu ya butterfly, valavu imodzi yokha ya butterfly imapangidwa.Axial Center, kubalalitsidwa, kuchepetsa extrusion kwambiri chapamwamba ndi m'munsi malekezero a mbale ndi mpando valavu.

Vavu ya butterfly yapakati

Chomangira cha valavu yagulugufe yapakati-mzere ndikuti tsinde lapakati pa tsinde, pakatikati pa diski ndi pakati pa thupi la valavu zili pamalo omwewo.Chifukwa mbale ya gulugufe ndi mpando wa valve nthawi zonse zimakhala zowonongeka ndi zowonongeka, mtunda wotsutsa ndi waukulu ndipo kuvala kumakhala mofulumira.Zosavuta komanso zosavuta kupanga.Pofuna kuthana ndi extrusion ndi kukanda kuti atsimikizire kusindikiza, mpando wa valve umapangidwa ndi zipangizo zotanuka monga mphira kapena PTFE.
