I-High Proformance Triple Eccentric Butterfly Valve Ephakeme Yokucindezela Okuphezulu En Pn16/25/40/63/100
Iyini i-valve ye-butterfly engavamile kathathu?
I-valve ye-butterfly engavamile kathathu,obeye aziwe njengoivalvu yebhabhathane eliphindwe kathathu, uhlobo olulodwa lwamavalvu ebhabhathane asebenza kahle kakhulu, aklanyelwe izimo zokusebenza zomfutho ophezulu, izinga lokushisa eliphezulu, kanye nemvamisa ephezulu yokuvula nokuvala.
Ivalvu yebhabhathane efakwe irabha eqondile, enomklamo ovuthiwe kanye nobuchwepheshe bokukhiqiza, ithembekile ngekhwalithi futhi ibiza kahle. Kodwa ngezicelo ezinzima njengamazinga okushisa aphezulu noma ngezikhathi zokuvula nokuvala eziphezulu, akuvunyelwe ukusebenzisa amavalvu ebhabhathane esihlalo esithambile. Ngakho-ke amavalvu ebhabhathane aqinile, isihlalo sensimbi noma isihlalo se-ceramic, aklanyelwe amazinga okushisa aphezulu, umfutho ophezulu noma amaza aphezulu okuvala okuvulekile, asetshenziswa, kodwa ukusebenza kokuvala kwevalvu yebhabhathane eqinisiwe yendabuko bekulokhu kuyinkinga enkulu.
Uma ivalvu ivaliwe, i-torque yendlela yokudlulisa inganda ukuze inikeze isinxephezelo. Lokhu kuthuthukisa kakhulu ukusebenza kokuvala kwe-i-valve ye-butterfly engavamile kathathufuthi kwandisa impilo yenkonzo yayo.
Ivalvu yebhabhathane eliyi-eccentric kathathu(eyaziwa nangokuthi i-triple offset butterfly valve) yasungulwa kulokhu.
Kunezici eziningi ze-amavalvu ebhabhathane aphindwe kathathu.Kukhona isihlalo sevalvu esihambisana nomzimba, esinama-engeli ezihlalo alungiselelwe kahle, esimbozwe ngezinto ezingagqokwa ezilungele izigidi zokuvula nokuvala, insimbi engagqwali yokumelana nokugqwala, kanye nezinto zokushisa okuphezulu. Futhi indandatho yokuvala ethambile enezingqimba eziningi noma indandatho yokuvala eqinile inamathele kudiski yebhabhathane. Lolu hlobo lomklamo luvumela ukuthi ivalvu yebhabhathane engavamile kathathu imelane kakhulu nokushaqeka kokushisa noma ukuphakama kwengcindezi kanye nokugqwala, uma kuqhathaniswa namavalvu ebhabhathane endabuko.
ukuvuza okungenalutho kwe-i-valve ye-butterfly engavamile kathathuisetshenziswa yindandatho yokuvala yensimbi engagqwali ehlanganisiwe efakwe kwidiski. Umklamo wokujikeleza okune-engeli yesokudla ngaphandle kokungqubuzana kwe-zero usetshenziswa yisimiso esihlukile se-triple eccentric. Iqeda ukungqubuzana phakathi kwesihlalo nendandatho yokuvala ngokujikeleza okungu-90º, I-torque encane isho ukuthi singayiqala i-valve nge-actuator encane, ukuze songe izindleko eziningi kanye nesikhala.
Umklamo we-Triple offsets
- I-offset yokuqala ukuthi i-valve shaft ingemuva kwe-disc shaft ukuze i-seal ikwazi ukuvala ngokuphelele isihlalo se-valve.
- I-offset yesithathu ukuthi i-axis yekhoni yesihlalo iyaphambuka kusukela enkabeni yeshaft yevalvu, okuqeda ukungqubuzana ngesikhathi sokuvala nokuvula futhi kufinyelele uphawu lokucindezela olufanayo oluzungeze sonke isihlalo.
Lokhu okungenhla yisingeniso se-i-valve ye-butterfly engavamile kathathu. Luhlobo lwevalvu yebhabhathane esebenza kahle kakhulu esetshenziswa njengamanje emikhakheni eminingi.
Izici eziyinhloko zamavalvu e-butterfly angavamile amathathu
- Izinkomba zediski evulekile/evaliwe kanye nesikhombisi sendawo yediski yangaphandle kwenza kube lula ukufaka/ukususa izinqubo ku-API 609.
- Indandatho yokuvala yensimbi ehlanganisiwe iqinisekisa ukusatshalaliswa okuphelele kwamandla okuhlala eduze komjikelezo wesihlalo oqondile.
- Ukubukeka kwe-flange spot kuqinisekisa ukulingana kwe-bolting nut kanye ne-washer, okwandisa ukuthembeka nokuphepha kwamalunga.
- Izindandatho zokuvala ze-duplex ne-graphite ezinezingqimba eziningi ezithathelwa indawo kalula.
- Umgodi oqiniswe kakhulu onengxenye eyodwa oklanyelwe ukudlulisa/ukugcina i-torque kahle.
- Izivikelo ze-graphite bearing ezilukiwe zivimbela ukungena kokungcola, ziqinisekisa i-torque esebenza njalo kanye nokusebenza kahle kwe-valve.
- Ukupakisha i-gland okunezingcezu ezimbili kanye nokupakisha i-graphite kunciphisa ingozi yokukhishwa kwangaphandle.
- Ukuxhumeka okuqinile kwe-shaft-to-disc ukuze kube nokuqina okuphezulu kwe-shaft.
