I-Triple Eccentric Butterfly Valve
yini i-valve ye-butterfly eccentric kathathu?
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.
Ziningi izici ze-ama-valve evemvane eccentric kathathu.Kukhona isihlalo sevalvu esihlanganisa umzimba wonke, esinama-engeli okuhlala athuthukisiwe, esimbozwe ngezinto ezivikela ukuguga ezifanele izigidi zokuvula nokuvala, insimbi engagqwali yokumelana nokugqwala, nezinto zokushisa okuphezulu. indandatho eqinile yokuvala ifakwe ku-butterfly disc.Lolu hlobo lomklamo oluvumela ukuthi lwenza i-valve uvemvane eccentric kathathu imelane kakhulu nokushaqeka okushisayo noma ukuphakama kwengcindezi nokugqwala, uma kuqhathaniswa namavalve ovemvane okuvamile.
ukuvuza kwe-zero kwethutriple eccentric butterfly valvekusetshenziswa indandatho eyinhlanganisela yensimbi engagqwali efakwe kudiski.Idizayini yokuzungezisa okuma-engeli angakwesokudla nokungqubuzana kuziro kusetshenziswa umgomo ohlukile we-eccentric kathathu.Iqeda ukungqubuzana phakathi kwesihlalo nendandatho yokuvala ngokuzungezisa okungu-90º, i-torque encane isho ukuthi singakwazi ukuqala i-valve nge-actuator encane, ukonga izindleko eziningi nesikhala.
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 zamavalvu evemvane eccentric kathathu
- Ukwakhiwa kwensimbi yonke ukumelana nomlilo.
- Izimbondela zezihlalo ze-Stellite® zebanga lesi-6 zinikeza ukuqina okuhle kakhulu.
- Ireferensi yediski evuliwe/evaliwe kanye nenkomba yendawo yediski yenza kube lula ukufakwa/izinqubo zokususa ku-API 609.
- Indandatho yensimbi eyinhlanganisela yophawu iqinisekisa ukusatshalaliswa kwamandla okuhlala okuphelele eduze komjikelezo wesihlalo owenziwe ngomshini.
- 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.
