I-NORTECHis enye yeChina ehamba phambiliUkusebenza okuphezulu kwe-butterfly valve Umkhiqizi nomhlinzeki.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Ithini Ivalve yevemvane esebenza kahle?

I-valve uvemvane esebenza kahle ingumkhiqizo wokuklama ophindwe kabili onobuchwepheshe obuhamba phambili emhlabeni.Le valve uvemvane inesakhiwo esiyingqayizivele esisebenza ngokuthembekile kakhulu, izimo zokusebenza ezibanzi kanye ne-torque ephansi yokusebenza.

Amavalvu ovemvane ane-eccentric ephindwe kabili, anendandatho yophawu eqiniswe ngepuleti lekhava, Izokwenza ivalvu ibe nendawo yokulungisa engami kumbuthano futhi yenze ivalve ingasithinti nhlobo isihlalo lapho sivulwa ngokuphelele.Lo mklamo uzokwenza ukungqubuzana kwesihlalo kunciphe futhi ngokufanelekile kuzonweba impilo yaso.Ekusetshenzisweni okuvamile, le valve ye-butterfly ebhalansi kabili-directional ikhawulelwe esigabeni 150.

Indandatho yokuvala i-valve ye-butterfly esebenza kahle yenziwe nge-elastomer fit ku-disc, iyatholakala ukuthi isetshenziselwe ukuvala uphawu ngendlela eyodwa, Evame ukusetshenziswa emanzini noma emanzini kamasipala.

Izici eziyinhloko ze-NORTECH I-valve yevemvane esebenza kahle?

Ukusebenza okuphezulu kwe-butterfly valve

Izinga lokuklama: BS EN593
Ubude bobuso nobuso: EN558-1/ISO5752 uchungechunge 14& ISO5752 uchungechunge 13
Ubukhulu be-Flange kanye nokubhoboza: BS EN1092/BS4504 (DIN2501)
Usayizi: DN350 - DN3000/14"-120"
Isilinganiso sokucindezela:PN6- PN10-PN16-PN25-PN40
Isicelo: amanzi, amanzi okuphuza, indle, uketshezi oluncane olugqwalile njll.

Izici eziyinhloko zeUkusebenza okuphezulu kwe-butterfly valve:

Impilo ende yesevisi ngenxa yediski etshekile

Ukungezwani kwe-disc kukhishwa ngemuva kokuvula amadigri ambalwa okunciphisa ukuguga kwe-disc seal.Ngaphezu kwalokho, umklamo unciphisa ukucindezelwa kokubekwa uphawu okuqinisekisa ama-torque aphansi okusebenza.

Imiklamo yezihlalo ezimbili

Idizayini yesihlalo esibalulekile inesihlalo sensimbi esifakwe ngomshini futhi esihlanganiswe ne-epoxy esihlanganiswe emzimbeni.Idizayini yesihlalo sensimbi engagqwali inendandatho yesihlalo eshintshwayo yensimbi engagqwali evalwe nge-O-ring ukuze kugwenywe ukuvuza ngaphansi kweringi yesihlalo.

Izici zokuklama shaft

Ukutywinwa kwe-shaft kuyashintshwa ngaphansi kwengcindezi ukuze kusebenze ukugcinwa kalula.Ukuvalwa kwe-EPDM kuvikela ukucinana kusuka ngaphakathi nangaphandle, futhi izigxivizo ze-NBR zivikela ekungcoleni nasemanzini angaphandle.

I-Disc seal elungiselelwe ukusebenza okuphezulu

I-disc seal yakhelwe ukuvikela ukulungiswa endaweni efanele ihlinzeka ngomsebenzi othembeke kakhulu.Ikhwalithi enhle kakhulu yerabha yenza kube lula ukunciphisa inani lerabha eliqinisekisa ama-torque aphansi okuvala.Ukuvalwa kwe-EPDM kuvunywe yi-ACS ne-WRAS.

I-valve ye-butterfly flange ephindwe kabili yohlobo 6

Uhlobo Lokusebenza Lwevalve yevemvane esebenzayo

ngoba High ukusebenza uvemvane valve, sinikeza

Ukusebenza kwe-gearbox okwenziwa ngesandla, i-pneumatic actuator, i-actuator kagesi, nama-hydraulic acatuators ongawakhetha.
