valavu ya butterfly ya Triple offset ndi chiyani?
Chovala cha valve ya butterfly cha katatu, amadziwikanso kutivalavu yamagulugufe atatu, ndi mtundu umodzi wa mavavu agulugufe apamwamba, opangidwa kuti azigwira ntchito mwamphamvu, kutentha kwambiri, komanso ma frequency apamwamba otseguka ndi kutseka.
Vavu yagulugufe yokhala ndi mphira yokhazikika, yokhala ndi mapangidwe okhwima ndiukadaulo wopanga, ndi yodalirika komanso yodalirika pamtengo. ma valve agulugufe osindikizira olimba, mpando wachitsulo kapena mpando wa ceramic, wopangidwira kutentha kwambiri, kuthamanga kwambiri kapena maulendo apakati otsegula, anayamba kugwiritsidwa ntchito, koma kusindikiza kwa valve yagulugufe yolimba kwambiri nthawi zonse kunali kovuta kwambiri.
kutayikira kwa zero kwathuatatu eccentric butterfly valveimayendetsedwa ndi mphete yosindikizira yachitsulo chosapanga dzimbiri yomwe imayikidwa pa disc.Kapangidwe ka kuzungulira kolowera kumanja ndi kukangana kwa ziro kumatsatiridwa ndi mfundo yosiyanitsa katatu.Imathetsa kukangana pakati pa mpando ndi mphete yosindikiza mu kuzungulira kwa 90º, torque yaying'ono imatanthawuza kuti titha kuyambitsa valavu ndi actuator yaying'ono, kuti tisunge ndalama zambiri komanso malo.
Mapangidwe a ma valve a butterfly offset katatu
- Chotsatira choyamba ndi chakuti shaft ya valve ili kuseri kwa shaft disk kotero kuti chisindikizo chikhoza kutseka kwathunthu mpando wonse wa valve.
- Chotsatira chachiwiri ndikuti mzere wapakati wa shaft wa valve umachotsedwa ku chitoliro ndi valve centerline kuti asasokonezedwe ndi kutsegula ndi kutseka kwa valve.
- Chotsalira chachitatu ndi chakuti mpando wa cone axis umachoka pakatikati pa shaft ya valve, yomwe imathetsa kukangana panthawi yotseka ndi kutsegula ndikukwaniritsa chisindikizo cha yunifolomu kuzungulira mpando wonse.
Pamwambapa ndikuyambitsa kwaatatu eccentric butterfly valve.Ndi mtundu wa valavu yagulugufe yogwira ntchito kwambiri yomwe imagwiritsidwa ntchito m'magawo ambiri.
Zinthu zazikulu za Triple offset butterfly valve lug
- Mphete yosindikizira yachitsulo yophatikizika imatsimikizira kugawa kwamphamvu kwapampando mozungulira mozungulira mpando wopangidwa ndi makina.
- Kuyang'ana kwa flange kumatsimikizira kukhazikika kwa mtedza ndi washer, kukulitsa kudalirika kwamagulu ndi chitetezo.
- Mphete zosindikizira zamitundu yambiri ndi ma graphite zosindikizira zimasinthidwa mosavuta.
- Shaft yokhala ndi gawo limodzi lolimba kwambiri lopangidwira kusamutsa / kusunga torque bwino.
- Zodzitchinjiriza zokhala ndi ma graphite zimalepheretsa kulowerera kwa dothi, kuwonetsetsa kuti torque ikuyenda mosalekeza komanso kugwira ntchito kwa valve.
- Kuyika kwa zidutswa ziwiri ndi kulongedza kwa graphite kumachepetsa chiopsezo chakunja.
- Kulumikizana kotetezedwa kwa shaft-to-disc kuti muchepetse kukhulupirika kwa shaft.
- Spiral bala gaskets, kusindikiza ndi kunyamula mphete zosinthika popanda zida zapadera.
- Ma bere olemetsa olemetsa amatha kupirira kupsinjika kwambiri komanso kuvala.
- Kuwongolera zoopsa za shaft extrusion mkati ndi kunja kumagwirizana ndi miyezo yapadziko lonse lapansi.
