API Aluminium Double/Triple Offset Lug/Wafer/Flange Gulugufe Valve Petrochemical Industry China factory
Kodi valavu ya gulugufe ya Triple offset ndi chiyani?
Valavu ya gulugufe yozungulira katatu,yomwe imadziwikanso kutivalavu ya gulugufe yotsika katatu, ndi mtundu umodzi wa ma valve a gulugufe ogwira ntchito bwino kwambiri, opangidwira mikhalidwe yogwirira ntchito ya kuthamanga kwambiri, kutentha kwambiri, komanso ma frequency apamwamba otseguka ndi kutseka.
Valavu ya gulugufe yokhala ndi rabara yozungulira, yokhala ndi kapangidwe kabwino komanso ukadaulo wopanga, ndi yodalirika komanso yotsika mtengo. Koma pakugwiritsa ntchito kwambiri monga kutentha kwambiri kapena pafupipafupi potsegula ndi kutseka, sikuloledwa kugwiritsa ntchito mavavu a gulugufe ofewa. Chifukwa chake mavavu a gulugufe olimba, mpando wachitsulo kapena mpando wa ceramic, wopangidwira kutentha kwambiri, kuthamanga kwambiri kapena pafupipafupi potsegula, adayamba kugwiritsidwa ntchito, koma magwiridwe antchito otseka a valavu ya gulugufe yolimba nthawi zonse anali nkhawa yayikulu.
kutayikira konse kwathuvalavu ya gulugufe yozungulira katatuimachitika pogwiritsa ntchito mphete yotsekera yachitsulo chosapanga dzimbiri yolumikizidwa pa diski. Kapangidwe ka kuzungulira kolunjika kumanja popanda kukangana kulikonse kamachitika pogwiritsa ntchito mfundo yapadera ya triple eccentric. Imachotsa kukangana pakati pa mpando ndi mphete yotsekera mu kuzungulira kwa 90º, Mphamvu yaying'ono imatanthauza kuti titha kuyambitsa valavu ndi actuator yaying'ono, kuti tisunge ndalama zambiri komanso malo ambiri.
Kapangidwe ka valavu ya gulugufe katatu
- Choyimitsa choyamba ndi chakuti shaft ya valavu ili kumbuyo kwa shaft ya disc kotero kuti chisindikizocho chitseke kwathunthu mpando wonse wa valavu.
- Choyimitsa chachiwiri ndi chakuti mzere wapakati wa shaft ya valavu umachotsedwa pa chitoliro ndi mzere wapakati wa valavu kuti zisasokonezedwe ndi kutsegula ndi kutseka kwa valavu.
- Choyimitsa chachitatu ndichakuti mzere wa cone wa mpando umachoka pakati pa shaft ya valve, zomwe zimachotsa kukangana panthawi yotseka ndi kutsegula ndipo zimapangitsa kuti pakhale chisindikizo chofanana chozungulira mpando wonse.
Zomwe zili pamwambapa ndi chiyambi chavalavu ya gulugufe yozungulira katatuNdi mtundu wa valavu ya gulugufe yogwira ntchito bwino yomwe imagwiritsidwa ntchito m'magawo ambiri.
Zinthu zazikulu za Triple offset butterfly valve lug
- Mphete yosindikizira yachitsulo chophatikizika imatsimikizira kufalikira kwa mphamvu ya mipando mozungulira mipando yokonzedwa bwino.
- Malo owonekera pa flange amatsimikizira kuti nati ya bolting ndi makina ochapira zimagwirizana bwino, zomwe zimapangitsa kuti malo olumikizirana azikhala odalirika komanso otetezeka.
- Mphete zosindikizira za duplex ndi graphite zomwe zimasinthidwa mosavuta.
- Shaft yolimba kwambiri yokhala ndi chidutswa chimodzi yopangidwa kuti isamutse/kusunga mphamvu moyenera.
- Zoteteza zokhala ndi graphite zolukidwa zimaletsa kulowerera kwa dothi, zomwe zimapangitsa kuti torque igwire ntchito nthawi zonse komanso kuti ma valavu azigwira ntchito bwino.
- Kupaka utoto wa gland ndi graphite yokhala ndi zidutswa ziwiri kumachepetsa chiopsezo cha kutulutsa mpweya kuchokera kunja.
- Kulumikizana kwa shaft-to-disc kotetezedwa ndi kiyi kuti shaft ikhale yolimba kwambiri.
- Ma gasket ozungulira, mphete zomatira ndi zopakira zimatha kusinthidwa popanda zida zapadera.
- Mabeya olemera amatha kupirira kupsinjika kwakukulu komanso kuwonongeka.
- Kusamalira zoopsa zotulutsa shaft mkati ndi kunja zikugwirizana ndi miyezo yapadziko lonse lapansi.

Kugwiritsa ntchito: Valavu ya gulugufe yozungulira katatu
Mtundu uwu waValavu ya gulugufe yozungulira katatu Ndi yoyenera kugwiritsa ntchito madzi osiyanasiyana m'mafuta ndi gasi, petrochemical, mankhwala, malasha, kuchotsa mchere m'madzi, mafakitale a chakudya ndi zakumwa. Komanso pamagetsi a dzuwa, geothermal ndi hydro, mafuta odzola, kutentha kwa madera, migodi, malo opangira sitima zapamadzi ndi m'magawo a ndege.
