Singeniso sekusetjentiswa, tintfo letiyinhloko kanye netimphawu tesakhiwo se-wafer check valve

Hlola ivalvu kusho ivalve levula ngekuzenzakalela futsi ivale i-valve flap ngekwetsembela ekugelezeni kwemkhatsi wona ngekwawo kuvikela kugeleta emuva kwemkhatsi, lokuphindze kwatiwe ngekutsi .hlola ivalvu, valve lehamba ngendlela yinye, valve yekugeleta emuva kanye nevalve yekucindzetela emuva. Ihlola ivalvuyi valve letentekelako umsebenti wayo lomkhulu kuvikela kubuyela emuva kwemkhatsi, kujikeleta lokubuyela emuva kwempompi kanye nemoto leshayelako, kanye nekukhishwa kwemkhatsi esitjeni. Emavalvu ekuhlola angaphindze asetjentiswe emigceni lephakela tinhlelo letisitako lapho khona umfutfo ungakhuphuka ngetulu kwemfutfo weluhlelo.

1.Tyena kusetjentiswa kwevalve yekuhlola i-wafer:

Ihlola ivalvu ifakwe eluhlelweni lwemaphayiphi, futsi umsebenti wayo lomkhulu kuvimbela kubuyela emuva kwemkhakha. Ihlola ivalvuyivalve letentekelako levulwako futsi ivalwe kuye ngekucindzeteleka lokusemkhatsini.Ivalvi yekuhlola i-wafer ilungele umfutfo wegama PN1.0 MPa ~ 42.0 MPa, Lizinga 150 ~ 25000; ububanzi lobubitwako DN15 ~ 1200mm, NPS1 / 2 ~ 48; Kubuyela emuva lokusemkhatsini. Ngekukhetsa tintfo letehlukene, ingasetjentiswa etindzaweni letehlukene letifana nemanti, umfutfo, oyili, i-nitric acid, i-acetic acid, i-oxidizing lecinile kanye ne-uric acid.

2.Tyena tintfo letiyinhloko teivalvu yekuhlola i-wafer:

Kukhona insimbi yekhabhoni, insimbi yekushisa lokuphansi, insimbi yesigaba lesimbili (F51/F55), i-titanium alloy, i-aluminium yelitfusi, i-INCONEL, i-SS304, i-SS304L, i-SS316, i-SS316L, i-chrome molybdenum insimbi, i-Monel (400/500), 2000.

3. Timphawu tesakhiwo se .ivalvu yekuhlola i-wafer:

A. Budze besakhiwo bufishane, futsi budze bayo besakhiwo bungu-1/4 ~ 1/8 kuphela we-valve yekuhlola ye-flange yendabuko .

B. Usayizi lomncane kanye nesisindvo lesilula, sisindvo sayo singu-1/4 ~ 1/20 kuphela we-valve yekuhlola ye-flange yendabuko

C. I valve disc ivala ngekushesha futsi umfutfo wesando semanti mncane .

D. Womabili emaphayiphi lavundlile noma lamaphayiphi lamile angasetjentiswa, kulula kuwafaka .

E. Umsele wekugeleta uyashelela futsi kumela kwemanti kuncane

F. Sento lesibucayi kanye nekusebenta kahle kwekuvala

G. Kuhamba kwe valve disc kufishane futsi emandla emtselela wekuvala mancane

H. Sakhiwo sonkhe silula futsi sincane, futsi nesimo sihle

I. Imphilo lendze yekusebenta kanye nekusebenta lokutsembekile

4.The emaphutsa lavamile evalve yekuhlola ngu:

A. Le disc ye valve yephukile

Kucindzeteleka kwemkhatsi ngaphambi nangemuva kwevalve yekuhlola isesimeni sekusondzela ekulinganiseni kanye ne “kubona” lokufanako. Le valve disc ivame kushaywa ngesihlalo se valve, bese le valve disc leyentiwe ngaletinye tintfo letiphukako (njengensimbi lephosiwe, litfusi, njll) iyaphuka. Indlela yekuvikela kutsi usebentise i-valve yekuhlola lene-disc njengentfo le-ductile.

B. Kubuyela emuva lokusemkhatsini

Indzawo yekuvala ilimele; kungcola kuyavaleleka. Ngekulungisa indzawo yekuvala kanye nekuhlanta kungcola, kugeleta emuva kungavinjelwa.
