Uhlobo lwe-Triple Eccentric Butterfly Valve Lug
Iyini uhlobo lwe-valve ye-butterfly eccentric kathathu?
Uhlobo lwe-valve ye-butterfly eccentric 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 uma kusetshenziswe kakhulu njengamazinga okushisa aphezulu noma uma kuvulwa futhi kuvalwa kakhulu, akuvunyelwe ukusebenzisa amavalvu ebhabhathane esihlalo esithambile.
Uhlobo lwe-valve ye-butterfly eccentric kathathu(eyaziwa nangokuthi i-triple offset butterfly valve) yasungulwa kulesi simo. Kunezici eziningi ze-uhlobo lwe-lug lwamavalvu ebhabhathane angavamile kathathu.T
Nasi 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.
Lapho i-valve is ivaliwe, i-torque yendlela yokudlulisa inganda ukuze inikeze isinxephezelo. Lokhu kuthuthukisa kakhulu ukusebenza kokuvala kweuhlobo lwe-valve ye-butterfly eccentric kathathufuthi kwandisa impilo yenkonzo yayo.
ukuvuza okungenalutho kwe-uhlobo lwe-valve ye-butterfly eccentric 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 yesibili ukuthi umugqa ophakathi we-valve shaft ususwa epayipini kanye nomugqa ophakathi we-valve ukuze kugwenywe ukuphazamiseka kokuvulwa nokuvalwa kwe-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-uhlobo lwe-valve ye-butterfly eccentric kathathu. Luhlobo lwevalvu yebhabhathane esebenza kahle kakhulu esetshenziswa njengamanje emikhakheni eminingi.
Izici eziyinhloko zama-valve e-butterfly aphindwe kathathu uhlobo lwe-lug
- Ukwakhiwa kwensimbi yonke okumelana nomlilo.
- Izimbozo zezihlalo ze-Stellite® zebanga lesi-6 zinikeza ukuqina okuhle kakhulu.
- 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.
- Ama-gasket enxeba elijikelezayo, izindandatho zokuvala kanye nokupakisha zingashintshwa ngaphandle kwamathuluzi akhethekile.
- Ama-bearings aqinile amelana nemithwalo ephezulu yokucindezela kanye nokuguguleka.
- Ukuphathwa kwengozi yokukhipha umgodi ngaphakathi nangaphandle kuhambisana nezindinganiso zomhlaba wonke.
