Ikhwalithi ephezulu Ivalvu yevemvane ye-offset ye-flange yase-China Umkhiqizi/ Umhlinzeki/imboni
yini i-Triple offset butterfly valve flange?
I-valve yevemvane eyi-eccentric kathathu,obeye aziwe njengotriple offset butterfly valve,iwuhlobo olulodwa lwamavalvu ovemvane asebenza kahle, aklanyelwe izimo zokusebenza zokucindezela okukhulu, izinga lokushisa eliphezulu, kanye namaza aphezulu okuvula nokuvala.
I-valve uvemvane enerabha eqinile, enomklamo ovuthiwe nobuchwepheshe bokukhiqiza, ithembekile ngekhwalithi futhi inobungane ngezindleko. ama-valve uvemvane ophawu oluqinile, isihlalo sensimbi noma isihlalo se-ceramic, esakhelwe izinga lokushisa eliphezulu, ingcindezi ephezulu noma amaza omsindo ovulekile, aqala ukusetshenziswa, kodwa ukusebenza kokuvala kwevalve yevemvane eqinile yendabuko kwakuhlala kukhathaza kakhulu.
I-valve yevemvane eyi-eccentric kathathu(eyaziwa nangokuthi i-triple offset butterfly valve) isungulwe kulesi simo.
Lapho i-valve ivaliwe, i-torque ye-transmission mechanism ingakhuphuka ukuze inikeze isinxephezelo.Lokhu kuthuthukisa kakhulu ukusebenza kokuvala uphawutriple eccentric butterfly valvefuthi yelula impilo yesevisi yayo.
Idizayini ye-Triple offsets
- I-offset yokuqala ukuthi i-valve shaft ingemuva kwe-disc shaft ukuze uphawu luvale ngokuphelele sonke isihlalo se-valve.
- I-offset yesibili ukuthi i-centerline ye-valve shaft isusiwe emgqeni wepayipi kanye ne-valve ukugwema ukuphazamiseka ekuvuleni nasekuvaleni kwe-valve.
- I-offset yesithathu iwukuthi i-axis ye-cone yesihlalo iphuma emgqeni ophakathi we-valve shaft, eqeda ukungqubuzana ngesikhathi sokuvala nokuvula futhi ifinyelele uphawu lokucindezela okufanayo eduze nesihlalo sonke.
Okungenhla ukwethulwa kwe-triple eccentric butterfly valve.Iwuhlobo lwevalve uvemvane olusebenza kahle kakhulu olusetshenziswa emikhakheni eminingi.
Izici eziyinhloko ze-Triple offset butterfly valve flange
- I-Flange spot ibheke kuqinisekisa ukubopha kwamantongomane kanye ne-washer planarity, okwandisa ukuthembeka kwamalunga nokuphepha.
- I-duplex enezendlalelo eziningi eshintshwa kalula nezindandatho zophawu lwe-graphite.
- Ishaft yocezu olulodwa eqiniswe kakhulu eklanyelwe ukudlulisa/ukugcina i-torque kahle.
- Izivikeli eziphethe i-graphite ezilukiwe zivimbela ukungena kokungcola, ziqinisekisa ukugijima kwe-torque nokusebenza kwamavalvu.
- Izingcezu ezimbili zokupakisha indlala kanye nokupakishwa kwegraphite kunciphisa ubungozi bokuphuma ngaphandle.
- Uxhumano oluvikelekile lwe-shaft-to-disc oluvikelwe ngokhiye ukuze uthole ubuqotho obukhulu be-shaft.
- Ama-gaskets amanxeba okuvunguza, ama-seal kanye nezindandatho zokupakisha ezishintshwayo ngaphandle kwamathuluzi akhethekile.
- Amabheringi esindayo amelana nemithwalo yengcindezi ephezulu nokuguga.
- Ukuphathwa kwengozi ye-shaft extrusion yangaphakathi nangaphandle kuthobela izindinganiso zamazwe ngamazwe.

Umbukiso Womkhiqizo:I-valve ye-butterfly ephindwe kathathu ye-offset
I-Appilcation: I-valve ye-butterfly flange kathathu
Lolu hlobo lwe-Triple offset butterfly valve flange lufanele ukuphatha uketshezi oluningi ku-oyela negesi, i-petrochemical, amakhemikhali, amalahle, ukukhipha usawoti emanzini, izimboni zokudla kanye neziphuzo.Futhi ngogesi welanga, i-geothermal kanye namandla aphehlwa ngamanzi, amafutha ezinto ezimbiwa phansi, ukushisisa isifunda, izimayini, izindawo zemikhumbi kanye nemikhakha ye-aerospace.
