Ingxoxo yolwazi lwe-Butterfly Valve

Eminyakeni yama-30s,I-butterfly valveYasungulwa e-United States, eyethulwa eJapan ema-50s, futhi yasetshenziswa kabanzi eJapan ngama-60s, futhi yathuthukiswa eChina ngemuva kwama-70s. Njengamanje, ama-butterfly valves angenhla kwe-DN300 mm emhlabeni athathe indawo kancane kancane ama-valve. Qhathanisa neama-gang valves, ama-butterfly ama-valves anokuvuleka okufushane nesikhathi sokuvala, i-torque encane yokusebenza, isikhala esincane sokufaka nesisindo esikhanyayo. Ukuthatha i-DN1000 njengesibonelo, i-valvevelvely valve imayelana ne-2T, kanti i-valueve valve imayelana ne-3.5T, futhi i-valvevelvelvelve valve kulula ukuyihlanganisa namadivayisi ahlukahlukene okushayela, ngokuqina nokuthembekile.

Ukungathandeki kophawu lwenjolobaI-butterfly valveNgabe lokho lapho kusetshenziselwa ukugcwala, ukucasuka kuzokwenzeka ngenxa yokusetshenziswa okungafanele, okuzokwenza isihlalo senjoloba sizolingisa bese silinyazwa. Eminyakeni yamuva nje, kwaqhamuka neChina yathuthukisa nama-batterfly valves wensimbi, futhi eminyakeni yamuva nje, iJapan iphinde yathuthukisa ama-valve abunjiwe evikelekile ngokumelana ne-cavitation, ukudlidliza okuphansi nomsindo ophansi nomsindo ophansi.

Impilo yenkonzo yesihlalo sokubekwa uphawu okujwayelekile yiminyaka eyi-15-20 ye-Rubber ne-80-90 iminyaka yensimbi ngaphansi kwezimo ezijwayelekile. Kodwa-ke, ungakhetha kanjani kahle ngokuya ngezidingo zezimo zokusebenza.

Ubudlelwano phakathi kokuvulwa kweI-butterfly valveFuthi izinga lokugeleza ngokuyisisekelo liqondile futhi lilingana. Uma kusetshenziselwa ukulawula isilinganiso sokugeleza, izici zayo zokugeleza nazo zihlobene kakhulu nokuvuselelwa kwamapayipi, okufana ne-porevere efakwe emapharevu amabili kuyafana, futhi isilinganiso sokulahleka kwepayipi sihlukile, futhi isilinganiso sokugeleza se-valve sizohluka kakhulu.

Uma i-valve isesimweni sokuthambisa okukhulu, emuva kwe-valve Plate ithambekele ekusebenzeni, futhi kungenzeka ukuthi kulimaze i-valve, ngakho-ke kuvame ukusetshenziswa ngaphandle kwe-15 °.

Lapho i-butterfly valve isendleleni ephakathi, ukwakheka kokuvula okwakhiwa yi-isivalwanaumzimba kanye nokuphela kwangaphambili kweplatefleply Plate kugxile emgodini we-valve, futhi izinhlangothi zombili zikha izifundazwe ezihlukile, futhi ngakolunye uhlangothi kuqhubekela phambili nokuvulwa kwamanzi okugeleza ngakolunye uhlangothi, futhi elinye uhlangothi luyafana nokuvulwa kwamanzi okugeleza, futhi uhlangothi lwe-nozzle luyashesha kakhulu Kunohlangothi olusha kakhulu, futhi ingcindezi engemihle izokhiqizwa ngaphansi kwe-throttle side valve, futhi uphawu lwenjoloba luvame ukuwela.

I-torque esebenzayo ye-butterfly valve, ngenxa yokuvula okuhlukile nokuvula kwe-valve, inani layo lihlukile, ikakhulukazi i-valve enkulu, ngenxa yokujula kwamanzi, ngenxa yokujula kwamanzi, ngenxa yokujula kwamanzi, kukhiqizwa ongezansi kwekhanda le-valve. Ngaphezu kwalokho, lapho i-elbow ifakiwe ohlangothini lwe-valve, kwakhiwa ukuhamba kwe-deflection, futhi kwanda i-torque. Lapho i-valve isekuvuleni okuphakathi, indlela yokusebenza idinga ukuzivalela ngenxa yesenzo se-torque yamanzi.
