I-Double Eccentric Butterfly Valve ye-Waterworks

I-Nortech double eccentric butterfly valve yezinhlelo zokusebenza zamanzi inikeza ukuvala okuthembekile, okune-torque ephansi kumapayipi amakhulu. I-geometry yediski ephindwe kabili iqeda ukuxhumana kwesihlalo okuqhubekayo ngesikhathi sokusebenza, yandisa kakhulu impilo yesevisi futhi inciphisa i-torque yokusebenza uma kuqhathaniswa nemiklamo eqondile. Itholakala ku-DN350–DN2000 (14″–80″), lawa ma-valve enzelwe ukuphakelwa kwamanzi kamasipala, izitshalo zokwelashwa kwamanzi, kanye nezinhlelo zamanzi ezimboni ezinkulu.

Umzimba wensimbi othambile kanye nediski enesihlalo se-EPDM noma se-NBR esingashintshwa kuqinisekisa ukusebenza kokuvala isikhathi eside kanye nokugcinwa okulula kwensimu. Kuhambisana ne-EN 593, i-API 609 kanye ne-AWWA C504. Ubuso nobuso ngokwe-ANSI B16.10, ISO 5752 Series 13/14, EN 558-1 Series 13/14. Isiphelo se-Flange ngokwe-ASME B16.5, B16.47, AWWA C207, EN 1092-2. Kuhlolwe ngokwe-API 598. Isilinganiso sokucindezela PN10/16/25, ANSI Class 150.

I-Nortech ingumkhiqizi nomhlinzeki we-AWWA we-valve yama-butterfly e-double eccentric eseShayina, ekhonza amaklayenti emisebenzi yamanzi kanye nezimboni emhlabeni jikelele.

I-Double Eccentric Butterfly Valve — Ikhasi Lomkhiqizo

Iyini i-Double Eccentric Butterfly Valve?

Iivalvu yebhabhathane ephindwe kabili— eyaziwa nangokuthi i-double offset butterfly valve — ine-disc geometry ehlukile lapho i-shaft isuswa khona kusukela ku-centerline yediski kanye no-centerline wepayipi. Lo mklamo we-dual offset uvumela idiski ukuthi isuke esihlalweni ngokushesha lapho ivulwa, isuse ukuxhumana okuqhubekayo phakathi kwediski nesihlalo ngesikhathi sokusebenza.

Umphumela uba ukwehla okukhulu kwe-torque yokusebenza, ukuguguleka kwesihlalo okuncishisiwe, kanye nokuphila isikhathi eside kwenkonzo uma kuqhathaniswa nama-valve e-butterfly aqinile. Uma ivuliwe ngokuphelele, idiski ayithinteki nhlobo nesihlalo, okuqinisekisa ukuthi indawo yokuvala ihlala ingonakali phakathi nezinkulungwane zemijikelezo yokusebenza.

Indandatho yokuvala yenziwe nge-elastomer, ifakwe kudiski futhi iboshwe ngepuleti lokumboza, yakha indawo yokuvala eqhubekayo, engaphazanyiswa ezungeze umjikelezo ogcwele. Lo mklamo unikeza ukusebenza kokuvala okuthembekile okuqondiswa kabili futhi uvame ukucaciswa emisebenzini yamanzi kamasipala, izitshalo zokuhlanza amanzi, kanye nezinhlelo zamapayipi amakhulu.

Ifanele ukusetshenziswa kokuvala okuqondene nohlangothi olulodwa kanye nohlangothi olubili. Isilinganiso sokucindezela esijwayelekile i-ANSI Class 150 / PN10 / PN16 / PN25.

Umklamo Ophindwe Kabili Ohlukile— i-double offset disc geometry isho ukuthi ama-disc cams asuka esihlalweni ngemva kokuvula amadigri ambalwa nje, okususa ukungqubuzana kwesihlalo phakathi nokushaya futhi kwandise kakhulu impilo yesihlalo uma kuqhathaniswa nemiklamo eqondile.

Akukho ukuxhumana kwesihlalo uma sivuliwe I-torque yokusebenza ephansi Ukuvalwa kwezinhlangothi ezimbili DN350–DN2000 Imisebenzi Yamanzi

Impilo yesevisi ende — ukwakheka kwediski elithambekile

Ukuqina kwediski kukhishwa ngemva kokuvulwa kwamazinga ambalwa, okunciphisa ukuguguleka kwesivalo sediski. Umklamo uphinde unciphise ukucindezelwa kwesihlalo, okuqinisekisa ukusebenza okuphansi kwe-torque kuyo yonke impilo ye-valve.

Imiklamo yezihlalo ezimbili iyatholakala

Umklamo wesihlalo ohlanganisiwe unesihlalo sensimbi esihlanganisiwe esenziwe ngomshini nesimbozwe nge-epoxy esihlanganiswe emzimbeni. Umklamo wesihlalo sensimbi engagqwali unikeza indandatho yesihlalo engashintshwayo evalwe ngendandatho ye-O ukuvimbela ukuvuza ngaphansi kwendandatho yesihlalo.

Umklamo womgodi — ungashintshwa ngaphansi kwengcindezi

Ukuvalwa kweshafti kungashintshwa ngokuphelele ngaphansi kwengcindezi, okwenza kube lula ukulungisa insimu ngaphandle kokuvalwa kwentambo. Izivalo ze-EPDM ziqinisekisa ukuqina kwangaphakathi; izivalo ze-NBR zivikela ekungcoleni kwangaphandle kanye nokungena koketshezi.

I-Disc seal ilungiselelwe ukusebenza kahle kakhulu

I-geometry yesivalo sediski iqinisekisa ukuqina kwesimo esifanele kanye nokusebenza okuthembekile. Inhlanganisela yerabha esezingeni eliphezulu ivumela ivolumu yesivalo encishisiwe, inikeze ama-torque aphansi okuvala. Ukuvalwa kwe-EPDM kuvunyelwe ukusetshenziswa kwamanzi aphuzwayo yi-ACS kanye ne-WRAS.

Ukuvalwa okuqondiswayo okuqondiswayo okuqondiswayo okubili kanye nokuqondiswayo okuqondiswayo kuyatholakala uma uceliwe
