Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Ayini ama-valve evemvane e-eccentric kabili?

I-Double Eccentric Butterfly Valveiwumkhiqizo wokuklama okuphindwe kabili okunobuchwepheshe obuphambili obuhamba phambili emhlabeni.Le valve yovemvane inesakhiwo esiyingqayizivele esinokwethenjelwa kokubekwa uphawu okuthembekile, izimo zokusebenza ezibanzi kanye ne-torque ephansi yokusebenza.

Indandatho yokuvala uvemvane eyi-eccentric ephindwe kabili yenziwe nge-elastomer fit ku-disc, iyatholakala ukuze isetshenziswe ekufakweni uphawu okukodwa, Okuvamise ukusetshenziswa emanzini noma ekufakweni kwamanzi kamasipala.

yini eyenza ihluke kuwo wonke amanye ama-valve ovemvane, i-double eccentric noma i-double offset disc design.

ivumela i-disc ukuthi isuke esihlalweni inciphisa i-torque nokuguga kwesihlalo, kuyinzuzo enkulu uma kuqhathaniswa nama-valve butterfly agxilile.

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 sivuleka ngokuphelele.Lo mklamo uzokwenza ukungqubuzana kwesihlalo kunciphe futhi ngokufanelekile kuzonweba ukuphila kwaso.Ekusetshenzisweni okuvamile, le valve yovemvane ebhalansi kabili-directional ikhawulelwe esigabeni 150.

KUNGANI USIKHETHA?

Qiqiniso kanye nenkonzo: iminyaka engaphezu kwengu-20 yokuhlangenwe nakho kwezinsizakalo ze-OEM/ODM zezinkampani ezihamba phambili zama-valve zaseYurophu.
QUkulethwa kwe-uick, ilungele ukuthunyelwa amasonto angu-1-4, nesitokwe esicabangelayo sama-valve e-butterfly ehlezi eqinile kanye nezingxenye
Qisiqinisekiso sokuphila izinyanga eziyi-12- 24 zamavalvu ovemvane ahlezi aqinile
Qisilawuli sesimo socezu ngalunye lwevalve uvemvane

Izici eziyinhloko ze Amavalvu erabha uvemvane eccentric kabili ahlezi:

Impilo ende yesevisi ngenxa yediski etshekile

Ukungezwani ku-disc kukhishwa ngemuva kokuvula amadigri ambalwa okunciphisa ukuguga kwe-disc seal.Ngaphezu kwalokho, umklamo unciphisa ukucindezelwa kokubekwa uphawu okuqinisekisa amatorque 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 nokwenzeka ukunciphisa inani lerabha eliqinisekisa ama-torque aphansi okuvala.Ukuvalwa kwe-EPDM kuvunywe yi-ACS ne-WRAS.

Ukuqina kwezinhlangothi ezimbili

Ama-valve anama-bi-directional futhi ahlukene ku-demae.

Isigxivizo esingashintshwa kudiski ngokulungiswa okungami
Idizayini ye-Double offset ibangela ukuguga kwezihlalo ezincane, i-torque ephansi
ukungqubuzana okuncane kuqinisekisa impilo ende yokusebenzisa
Indandatho yokuvala evuselelekayo
I-Epoxy paint body&disc
I-ISO 5211 flange ephezulu yokusebenza okuhlukahlukene
Ukuvuza okunguziro nhlangothi zombili

I-valve ye-butterfly flange ephindwe kabili yohlobo 6

Uhlobo Lokusebenza lwerabha ye-Double Eccentric Butterfly Valve ehlezi

okweAmavalvu erabha uvemvane eccentric kabili ahlezi, siyahlinzeka

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