Ivalvu Yebhabhathane Ephindwe Kabili Engajwayelekile
Iyini i-Double Eccentric Butterfly Valve?
Ivalvu Yebhabhathane Ephindwe Kabili Engajwayelekile iwumkhiqizo omusha womklamo we-double offset onobuchwepheshe obuphambili emhlabeni. Le valve ye-butterfly inesakhiwo esiyingqayizivele esinokusebenza kokuvala okuthembekile kakhulu, izimo zokusebenza ezibanzi kanye ne-torque ephansi yokusebenza.
Izici eziyinhloko zamavalvu ebhabhathane aphindwe kabili yi-eccentric ephindwe kabili, ebizwa nangokuthi umklamo wediski ephindwe kabili.
Ivumela idiski ukuthi isuke esihlalweni inciphise i-torque egijimayo kanye nokuguguleka kwesihlalo, kuyinzuzo enkulu uma kuqhathaniswa nama-valve e-butterfly aqinile.
Ukucindezeleka kwediski kukhishwa ngemva kokuvulwa kwamazinga ambalwa okunciphisa ukuguguleka kwe-disc seal. Ngaphezu kwalokho, umklamo unciphisa ukucindezelwa kwe-seal okuqinisekisa ukusebenza okuphansi kwama-torque.
Ukuvalwa kweshaft kungashintshwa ngaphansi kwengcindezi ukuze kube lula ukugcinwa. Ukuvalwa kwe-EPDM kuqinisekisa ukuqina ngaphakathi nangaphandle, kanti ukuvalwa kwe-NBR kuvikela ekungcoleni nasezintweni eziphuma ngaphandle.
Ama-bearings e-PTFE anokungqubuzana okuphansi aqinisekisa ama-torque aphansi okusebenza kanti iziphetho zomgodi ovikelwe ziqinile njengoba kungekho izindawo zensimbi ezingamboziwe ezivezwe kuma-media.

Umshini wokuvala uphawuIvalvu Yebhabhathane Ephindwe Kabili Engajwayelekile
Izici eziyinhloko zeAmavalvu ebhabhathane e-NORTECH aphindwe kabili
- Idizayini yesihlalo se-PTFE esivalwe ngendlela eguquguqukayo eyingqayizivele iyaguquguquka futhi ithembeke kakhulu
- Isakhiwo sesivalo sezindebe singalungisa izinguquko ekushiseni nasekucindezelweni, gcina isivalo
- Impilo yenkonzo ende, impilo yelabhorethri ingafika ezikhathini ezingu-670,000
- Ukusebenza kwe-seal okuthembekile kakhulu: ukuvuza kwe-zero okuqondisayo okubili
- Kulula ukufaka isihlalo esikhundleni saso ngokususa into efakiwe, kulula ukuyilungisa.
- Kukhona isakhiwo esiphephile sokuqhumisa phezulu kwesiqu
- Izici ezinhle kakhulu zokulungisa
- Umklamo ongangeni umlilo
Umshini wokuvala uphawuIvalvu Yebhabhathane Ephindwe Kabili Engajwayelekile
Uhlobo lwe-Stem-upstream
Uma i-media igeleza isuka ngemuva kwe-valve ye-butterfly iye ngaphambili, ipuleti le-butterfly lizivalela lona ngenxa yokusunduza phezulu kwe-media kanye nokucindezela kwesihlalo.
Uhlobo lwe-Stem-downstream
Uma i-media igeleza isuka ngaphambili kwe-valve ye-butterfly iye ngemuva, i-medium ikhiqiza i-thrust ekhoneni langemuva kwesihlalo bese ipuleti le-butterfly lakha i-pressure self-sealing.
Uhlobo Lokusebenza lwe-Double Eccentric Butterfly Valve
Isibambo se-valve yebhabhathane eqinile i-DN40-DN200.
Umqhubi wegiya lesandla lamavalvu ebhabhathane aphelele.
I-actuator yomoya yohlu oluphelele lwama-valve e-butterfly
I-actuator kagesi yohlu oluphelele lwama-valve e-butterfly
Isiqu samahhala esingenawo umshayeli, senzelwe amakhasimende anezinjini zakho zokushayela.

Umbukiso Womkhiqizo:
I-Double Eccentric Butterfly Valve isetshenziselwani?
Ukusebenza okuphezuluivalvu yebhabhathane ephindwe kabiliizinhlelo zokusebenza
1: Izimo zokusebenza ezisheshayo kakhulu ezivame kakhulu: ohlelweni lokuhlukanisa umoya, zingenziwa isikhathi eside ngaphakathi kweswishi yesekhondi eli-1,
Isikhathi sokuphila singafinyelela izikhathi eziyisigidi
2: Izimo zokusebenza zokushisa okuphezulu: Isihlalo sezinto ze-PPL sifanele amazinga okushisa aphezulu angama-degrees Celsius angama-250.
3: Izimo zokuvala ezinezinhlangothi ezimbili ezinengcindezi ephezulu: ohlelweni lokuqeda i-condensate lunezinhlelo zokusebenza eziningi ezahlukene.
4: Izimo zokusebenza kwe-oksijini: Le valve ngemva kokwelashwa kokususa amafutha ingasetshenziswa ezimweni zokusebenza kwe-oksijini, ezingxenyeni ezithile
Ngokuphathelene nokulungiselela, ukuhlanganisa, ukuhlola kanye nokupakishwa, ivalvu ihlanzwa ngokuhambisana nezinqubo.
5: Izimo ze-vacuum: uphawu olujwayelekile lwe-valve ye-butterfly esebenza kahle kakhulu (ephindwe kabili) olulinganiselwe ukuze kufezwe i-vacuum
2x10-2. Amavalvu akhethekile aphezulu okuhlanza anesivalo se-vacuum esingu-2x10-5 nawo ayatholakala.
