I-Double Eccentric Butterfly Valve
Iyini i-Double Eccentric Butterfly Valve?
I-Double Eccentric Butterfly Valve iwumkhiqizo wokuklama okuphindwe kabili okunobuchwepheshe obuphambili obuhamba phambili emhlabeni.Le valve yovemvane inesakhiwo esiyingqayizivele esinokwethenjelwa kokubekwa uphawu okuthembekile, izimo zokusebenza ezibanzi kanye ne-torque ephansi yokusebenza.
izici eziyinhloko zama-valve uvemvane ane-eccentric kabili i-double eccentric, ebuye ibizwe ngokuthi i-double offset disc design.
ivumela i-disc ukuthi isuke esihlalweni inciphisa i-torque nokuguga kwesihlalo, kuyinzuzo enkulu uma kuqhathaniswa nama-valve butterfly agxilile.
Ukungezwani ku-disc kukhishwa ngemuva kokuvula amadigri ambalwa okunciphisa ukuguga kwe-disc seal.Ngaphezu kwalokho, umklamo unciphisa ukucindezelwa kokubekwa uphawu okuqinisekisa amatorque aphansi okusebenza.
Ukutywinwa kwe-shaft kuyashintshwa ngaphansi kwengcindezi ukuze kusebenze ukugcinwa kalula.Ukuvalwa kwe-EPDM kuvikela ukucinana kusuka ngaphakathi nangaphandle, futhi izigxivizo ze-NBR zivikela ekungcoleni nasemanzini angaphandle.
Amabheringi e-PTFE ashayisana kancane aqinisekisa ama-torque aphansi okusebenza kanye neshaft evikelwe iqeda ukuqina okuvikelekile njengoba zingekho izindawo zensimbi ezimbozekile ezivezwe kwabezindaba.
Izici eziyinhloko zama-Double eccentric butterfly valves
Umshini wokufaka uphawu weI-Double Eccentric Butterfly Valve
Izici eziyinhloko zeI-NORTECH ama-valve evemvane e-eccentri ephindwe kabili
- Idizayini yezihlalo ze-PTFE eziguquguqukayo eziguquguqukayo ezivaliwe iyashintshashintsha futhi ithembeke kakhulu
- Isakhiwo se-lip seal singakhokhela izinguquko ekushiseni nasekucindezelweni, gcina uphawu
- Impilo ende yesevisi, impilo yaselabhorethri ingaba izikhathi ezifika ku-670,000
- Ukusebenza kophawu okuthembeke kakhulu:ukuvuza kwe-bi-directional zero
- kulula ukushintsha isihlalo ngokususa into efakwayo, elungele ukulungiswa.
- Kunesakhiwo esiphephile sokushaywa umoya phezulu kwesiqu
- Izici zokulungisa ezinhle kakhulu
- Umklamo wokufakazela umlilo
Umshini wokufaka uphawu weI-Double Eccentric Butterfly Valve
Uhlobo lwe-Stem-upstream
Lapho imidiya igeleza isuka ngemuva kwe-valve uvemvane iya phambili, ipuleti levemvane liyazivala ngokwalo ngenxa yokukhuphuka kwabezindaba nokucindezela kwesihlalo.
Uhlobo lwe-Stem-downstream
Uma imidiya igeleza isuka ngaphambili kwevalve uvemvane iye ngemuva, i-medium ikhiqiza ukusunduza nge-engeli engemuva kwesihlalo bese ipuleti levemvane lenza ukuzivala kwengcindezi ngokwalo.
Uhlobo Lokusebenza Lwevaluvu Yevemvane Ye-Eccentric Ephindwe Kabili
Bamba i-lever yamavalvu ovemvane aqinile DN40-DN200.
Osebenzisa u-gearbox osebenza ngezandla wamavalvu evemvane ahlukene.
I-actuator ye-pneumatic yohlu olugcwele lwamavalve ovemvane
I-actuator kagesi yohlu olugcwele lwamavalvu ovemvane
Isiqu samahhala ngaphandle kwe-actuator, eyenzelwe amaklayenti ngama-actuator akho.

Umbukiso Womkhiqizo:
Isetshenziselwa ini i-Double Eccentric Butterfly Valve?
Ukusebenza okuphezului-valve ye-butterfly ephindwe kabiliizicelo
I-1: Izimo zokusebenza ze-high-speed high-frequency: ohlelweni lokuhlukanisa umoya, lungenziwa isikhathi eside ngaphakathi kokushintsha kwesekhondi elingu-1,
Isikhathi sokuphila singafinyelela izikhathi eziyizigidi ezingu-1
2: Izimo zokusebenza eziphezulu zokushisa: Isihlalo sempahla ye-PPL sifanele amazinga okushisa aphezulu angama-250 degrees C.
I-3: Izimo zokuvala uphawu ze-high-pressure double-side 6-stage: ohlelweni lokuqeda i-condensate lunohlu olubanzi lwezinhlelo zokusebenza.
I-4: Izimo zokusebenza kwe-oksijeni: Le valve ngemva kokwelashwa kwe-degreasing ingasetshenziselwa izimo zokusebenza ze-oxygen, ezingxenyeni
Ngokuphathelene nokulungiselela, ukuhlanganisa, ukuhlolwa nokupakisha, i-valve ihlanzwa ngokuhambisana ngokuqinile nezinqubo.
5: Izimo zevacuum: ukusebenza okuphezulu okujwayelekile (i-double eccentric) ivalve uvemvane elinganiselwe uphawu ukuze kufinyelelwe isikhalazo
2x10-2.Ama-valve akhethekile aphezulu ane-vacuum ye-2x10-5 ayatholakala.
