High Performance welded Type Triple Offset Butterfly Valve China fakitale
Kodi valavu ya gulugufe ya katatu yotsekedwa ndi chiyani?
Valavu ya gulugufe yocheperako katatu (yomwe imadziwikanso kuti valavu ya gulugufe ya triple offset) yapangidwa pankhaniyi.
Pali makhalidwe ambiri akatatukuchepetsama valve a gulugufe.Pali mpando wa valavu wogwirizana ndi thupi, wokhala ndi ngodya zabwino zokhalamo, wokutidwa ndi zinthu zosagwiritsidwa ntchito movutikira zoyenera kutsegulira ndi kutseka mamiliyoni ambiri, chitsulo chosapanga dzimbiri choteteza dzimbiri, ndi zipangizo zotetezera kutentha kwambiri. Ndipo mphete yofewa yotsekera yokhala ndi zigawo zambiri kapena mphete yotsekera yolimba imakhazikika pa diski ya gulugufe. Kapangidwe kamtunduwu kamalola kuti valavu ya gulugufe yozungulira katatu ikhale yolimba kwambiri ku kutentha kwambiri kapena kupsinjika ndi dzimbiri, poyerekeza ndi mavalavu a gulugufe achikhalidwe.
Valavu ya gulugufe yocheperako 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 kwathukatatukuchepetsavalavu ya gulugufeimachitika 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.
valavu ya gulugufe yotsika katatukapangidwe
- 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 yotsika katatuNdi mtundu wa valavu ya gulugufe yogwira ntchito bwino yomwe imagwiritsidwa ntchito m'magawo ambiri.
Zinthu zazikulu za ma valve a gulugufe atatu otsekedwa
- Kapangidwe ka zitsulo zonse kosagwira moto.
- Zophimba mipando ya Stellite® ya giredi 6 zimapereka kulimba kwabwino kwambiri.
- Zolemba za ma disc otseguka/otsekedwa ndi chizindikiro cha malo a disk yakunja zimapangitsa kuti njira zokhazikitsira/kuchotsa zikhale zosavuta ku API 609.
- Mphete yosindikizira yachitsulo chophatikizika imatsimikizira kufalikira kwa mphamvu ya mipando mozungulira mipando yokonzedwa bwino.
- 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.
