Valve ya Gulugufe Wambiri
Kodi Double Eccentric Butterfly Valve ndi chiyani?
Valve ya Gulugufe Wambiri ndi chida chopangidwa mwaluso chapawiri chomwe chili ndiukadaulo wapamwamba kwambiri padziko lonse lapansi.Valve yagulugufe ili ndi mawonekedwe apadera omwe ali ndi magwiridwe antchito odalirika kwambiri, malo ogwirira ntchito ambiri komanso torque yotsika.
Chizindikiro chachikulu cha ma valve agulugufe omwe ali pawiri ndi eccentric, yomwe imatchedwanso kuti double offset disc design.
imalola kuti chimbalecho chisunthike pampando ndikuchepetsa kuthamanga kwa torque ndi kuvala kwa mipando, ndi mwayi waukulu poyerekeza ndi mavavu agulugufe omwe amakhala.
Kuthamanga kwa diski kumatulutsidwa pambuyo pa madigiri angapo otsegula omwe amachepetsa kuvala kwa chisindikizo cha disc.Kuphatikiza apo, mapangidwewo amachepetsa kuponderezedwa kwa kusindikiza komwe kumatsimikizira ma torque otsika.
Kusindikiza kwa shaft kumasinthidwanso mokakamizidwa kuti athe kukonza mosavuta.Kusindikiza kwa EPDM kumateteza kumangika kuchokera mkati ndi kunja, ndipo zosindikizira za NBR zimateteza ku zonyansa ndi zamadzimadzi zochokera kunja.
Mapiritsi otsika a PTFE amatsimikizira kuti ma torque ocheperako amagwirira ntchito ndipo shaft yotetezedwa imatha kukhazikika chifukwa palibe chitsulo chosatsekedwa chowululidwa ndi media.
Zofunikira zazikulu za Double eccentric butterfly mavavu
Kusindikiza makina aValve ya Gulugufe Wambiri
Mbali zazikulu zaNORTECH mavavu agulugufe awiri a eccentri
- Mapangidwe apadera a mipando ya PTFE yosindikizidwa ndi mphamvu ndi yosinthika komanso yodalirika kwambiri
- Kapangidwe ka milomo yosindikizira kumatha kubweza kusintha kwa kutentha ndi kupanikizika, sungani chisindikizo
- Moyo wautali wautumiki, moyo wa labotale ukhoza kufika nthawi 670,000
- Kuchita zosindikizira zodalirika kwambiri: bi-directional zero leak
- ndikosavuta kusintha mpando pochotsa choyikapo, chosavuta kukonza.
- Pamwamba pa tsinde pali malo otetezeka ophulika
- Makhalidwe abwino osintha
- Kupanga umboni wamoto
Kusindikiza makina aValve ya Gulugufe Wambiri
Mtundu wa Stem-upstream
Pamene zofalitsa zimayenda kuchokera kumbuyo kwa valavu ya butterfly kupita kutsogolo, mbale ya butterfly imadzisindikiza yokha chifukwa cha kukweza kwa TV ndi kupanikizika kwa mpando.
Mtundu wa tsinde-pansi
Makanema akamayenda kuchokera kutsogolo kwa gulugufe kupita kumbuyo, sing'angayo imapanga kukankhira kumbuyo kwa mpando ndipo mbale yagulugufe imapangitsa kuti idzisindikize yokha.
Mtundu wa Ntchito ya Double Eccentric Butterfly Valve
Chogwirizira chowongolera cha mavavu agulugufe olimba DN40-DN200.
Ogwiritsa ntchito pamanja a gearbox amitundu yonse ya agulugufe.
Pneumatic actuator yamitundu yonse ya mavavu agulugufe
Choyatsira magetsi chamitundu yonse ya mavavu agulugufe
Tsinde laulere popanda actuator, lopangidwira makasitomala omwe ali ndi makina anu.

Chiwonetsero cha malonda:
Kodi Double Eccentric Butterfly Valve amagwiritsidwa ntchito bwanji?
Kuchita bwino kwambirivalavu yagulugufe yawiri eccentricmapulogalamu
1: Mayendedwe othamanga kwambiri othamanga kwambiri: munjira yolekanitsa mpweya, zitha kuchitika kwa nthawi yayitali mkati mwa masekondi 1,
Kutalika kwa moyo kumatha kufika nthawi 1 miliyoni
2: Kutentha kwakukulu kogwirira ntchito: Mpando wa PPL ndi woyenera kutentha kwambiri kwa 250 ° C.
3: Kusindikiza kwapang'onopang'ono kwapawiri-mbali 6-masitepe osindikizira: mu dongosolo lomaliza la condensate lili ndi ntchito zambiri.
4: Mikhalidwe yogwiritsira ntchito mpweya: Valavu iyi pambuyo pa chithandizo cha degreasing ingagwiritsidwe ntchito pazigawo zogwiritsira ntchito mpweya, mbali zina
Pankhani yokonzekera, kusonkhanitsa, kuyesa ndi kuyika, valve imatsukidwa motsatira ndondomeko.
5: Zinthu zotsekemera: mawonekedwe apamwamba kwambiri (kawiri eccentric) agulugufe ovotera chisindikizo kuti akwaniritse vacuum
2x10-2.Mavavu apadera apamwamba okhala ndi vacuum ya 2x10-5 amapezekanso.
