Valavu ya gulugufe ya Triple Offset BW Yapamwamba Kwambiri China Wopanga/Wogulitsa/ fakitale
Kodi valavu ya gulugufe ya Triple offset BW ndi chiyani?
Valavu ya gulugufe yotsika katatu BW, 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.
Valavu ya gulugufe yozungulira katatu(yomwe imadziwikanso kuti valavu ya gulugufe ya triple offset) yapangidwa pankhaniyi.
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.
Zinthu zazikulu za valavu ya gulugufe ya Triple offset BW
- 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.
- 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.
