Valavu ya Gulugufe Yachiwiri Yozungulira
Kodi valavu ya gulugufe ya Double Eccentric ndi chiyani?
Valavu ya Gulugufe Yachiwiri Yozungulira ndi chinthu chatsopano chopangidwa ndi kapangidwe ka double offset chokhala ndi ukadaulo wapamwamba kwambiri padziko lonse lapansi. Valavu ya gulugufe iyi ili ndi kapangidwe kake kapadera kokhala ndi magwiridwe antchito odalirika kwambiri, magwiridwe antchito ambiri komanso mphamvu yochepa yogwirira ntchito.
Makhalidwe akuluakulu a ma valve a gulugufe awiri osasunthika ndi awiri osasunthika, omwe amatchedwanso kapangidwe ka ma disc awiri osasunthika.
Zimalola kuti diski isunthe kuchoka pampando, zomwe zimachepetsa mphamvu yothamanga komanso kuwonongeka kwa mipando, ndi mwayi waukulu poyerekeza ndi ma valve a gulugufe ozungulira.
Kupsinjika kwa diski kumatulutsidwa pambuyo potseguka pang'ono zomwe zimachepetsa kuwonongeka kwa chisindikizo cha diski. Kuphatikiza apo, kapangidwe kake kamachepetsa kupsinjika kwa kutseka komwe kumatsimikizira kuti ma torque ogwirira ntchito ndi ochepa.
Kutseka kwa shaft kumatha kusinthidwa mukapanikizika kuti kukhale kosavuta kukonza. Kutseka kwa EPDM kumateteza kulimba mkati ndi kunja, ndipo kutseka kwa NBR kumateteza ku zinyalala ndi madzi ochokera kunja.
Ma bearing a PTFE otsika kwambiri amatsimikizira kuti ma torque ogwirira ntchito ndi otsika ndipo ma shaft otetezedwa amakhala olimba chifukwa palibe malo achitsulo osaphimbidwa omwe amawonetsedwa pa media.
Zinthu zazikulu za ma valve awiri a gulugufe osakanikirana

Zinthu zazikulu zaMa valve a gulugufe awiri a NORTECH eccentri
- Kapangidwe kapadera ka mpando wa PTFE wotsekedwa ndi mphamvu ndi kosinthasintha komanso kodalirika kwambiri
- Kapangidwe ka chisindikizo cha milomo kangathe kulipira kusintha kwa kutentha ndi kuthamanga, sungani chisindikizocho
- Moyo wautali wautumiki, nthawi ya labotale imatha kufika nthawi 670,000
- Kugwira ntchito kwa chisindikizo chodalirika kwambiri: kutayikira kwa ziro ziwiri
- N'zosavuta kusintha mpando pochotsa choyikapo, chomwe ndi chosavuta kukonza.
- Pamwamba pa tsinde pali malo otetezeka oti mutulutsepo
- Makhalidwe abwino kwambiri osinthira
- Kapangidwe kosapsa ndi moto

Mtundu wa tsinde lokwera
Pamene cholumikizira chikuyenda kuchokera kumbuyo kwa valavu ya gulugufe kupita kutsogolo, mbale ya gulugufe imadzitseka yokha chifukwa cha kukankhira kwa cholumikizira mmwamba ndi kukakamizidwa kwa mpando.
Mtundu wa tsinde lotsika
Pamene cholumikizira chikuyenda kuchokera kutsogolo kwa valavu ya gulugufe kupita kumbuyo, cholumikiziracho chimapanga mphamvu yopondereza kumbuyo kwa mpando ndipo mbale ya gulugufe imapanga mphamvu yodzitsekera yokha.
Mtundu wa Ntchito ya Valavu ya Gulugufe Yachiwiri Yopanda Kukhazikika
Chogwirira cha ma valve a gulugufe olimba DN40-DN200.

Chiwonetsero cha Zamalonda:
Kodi valavu ya gulugufe ya Double Eccentric imagwiritsidwa ntchito pa chiyani?
Kuchita bwino kwambirivalavu ya gulugufe iwiri yosiyanamapulogalamu
1: Mikhalidwe yogwirira ntchito yothamanga kwambiri: mu dongosolo lolekanitsa mpweya, ikhoza kuchitika kwa nthawi yayitali mkati mwa switch imodzi,
Moyo wa munthu ukhoza kufika nthawi miliyoni imodzi
2: Mikhalidwe yogwirira ntchito yotentha kwambiri: Mpando wa zinthu za PPL ndi woyenera kutentha kwambiri kwa madigiri 250 Celsius.
3: Mikhalidwe yotsekera yolimba kwambiri mbali ziwiri yokhala ndi magawo 6: mu dongosolo lomaliza la condensate lili ndi ntchito zambiri.
4: Mikhalidwe yogwiritsira ntchito mpweya: Valavu iyi ikatha kuchotsedwa mafuta ingagwiritsidwe ntchito pamikhalidwe yogwiritsira ntchito mpweya, m'zigawo zina
Ponena za kukonzekera, kusonkhanitsa, kuyesa ndi kulongedza, valavu imatsukidwa motsatira njira zonse.
5: Mikhalidwe ya vacuum: vavu ya gulugufe yodziwika bwino (yokhala ndi mawonekedwe awiri) yovomerezeka kuti ikwaniritse vacuum
2x10-2. Ma valve apadera okhala ndi vacuum yambiri okhala ndi vacuum ya 2x10-5 akupezekanso.
