Unokukhetha njani ivalve yokujonga intsimbi engenasici?

Ivalve yokujonga intsimbi engenastainless yivalve ezenzekelayo enemifuziselo emininzi kunye neenkcukacha.Olu hlobo lwemveliso lusetyenziselwa ukuthintela umva we-medium, ukujikeleza okujikelezayo kwempompo kunye ne-motor yayo yokuqhuba, kunye nokukhutshwa kwe-medium kwi-container.Ingasetyenziswa kwizinto ezahlukeneyo kumgca ophakathi.Ngoko ke, sikhetha njani ivalve yokujonga intsimbi engenastainless?Yintoni efanele kuqwalaselwe?

1. Ngokuqhelekileyo kucetyiswa ukuba abasebenzisi bakhethe iivalvu zokujonga intsimbi etywiniweyo ukuqinisekisa ukuba iivalvu zokukhangela i-wafer zinobomi obude benkonzo, ubushushu obuphezulu bokusebenza, kunye nokusebenza okufanayo kokutywinwa.

2. Ukuba ubungakanani begama bukhulu kuno okanye bulingana no DN100 (NPS4), kuyacetyiswa ukuba ukhetheH76 uhlobo idiskhi kabini ujingi ivalufa yokujonga, enokunciphisa ngokufanelekileyo ukulahlekelwa kokuchasana kwamanzi kwi-valve yokutshekisha;ubukhulu begama bungaphantsi okanye bulingana ne-DN80 (NPS3), kwaye ukhetho lwe-H71 uhlobo lokuphakamisa i-valve yokukhangela ifanelekile.

3. IIvalve yokukhangela i-wafer ye-H71kunye nobukhulu begama obungaphantsi okanye obulingana ne-DN100 (NPS) ngokubanzi ayiveliswanga ngenxa yobume bayo obubambeneyo kunye nokuqwalasela inkqubo kunye nenkqubo yokuvelisa.Kucetyiswa ukuba abasebenzisi bakhethe iivalvu zetshekhi zentsimbi engenastainless.ivalve.

4. Ukongeza kuhlobo lwe-wafer, i-stainless steel stainless double disc swing check valve nayo inohlobo lwe-lug kunye nohlobo lwe-flange.Ukuba umsebenzisi akanazo iimfuno ezikhethekileyo, ifom yolwakhiwo ngokubanzi yenziwa yinkampani yethu ngokwemigangatho eqhelekileyo.Ezinye iivalve zokujonga idiskhi eziphindwe kabini zinokuyilwa kunye nesakhiwo seflange ephindwe kabini (uhlobo lwe-H46).

5. I-lug flange ye-lug i-double flap swing check valve idlala indima yokubeka kuphela, kwaye i-lug ayithwali amandla e-bolt, ngoko ubukhulu be-lug flange abuyilwanga ngokobukhulu be-flange eqhelekileyo, ngokuqhelekileyo. I-lug flange Ubungqingqwa bungaphantsi kobu-flanges eziqhelekileyo.I-flange yoqhagamshelwano oluphindwe kabini lwe-disc swing check valve ithwala amandla ebholithi, kwaye ubukhulu be-flange buyilwe ngokuhambelana nomgangatho we-flange.

6. I-valve yokukhangela i-wafer ye-wafer ene-nominal pressures i-PN10, i-PN16, i-PN25 kunye ne-PN40 inoluhlu olubini ubude besakhiwo.Ixabiso leevalve ezimfutshane zokutshekisha lisezantsi, kodwa iigaskets zoqhagamshelo ezingekho mgangathweni zingafuneka phakathi kwevalve yokukhangela kunye neflange yombhobho.Ukuba i-valve yokukhangela i-long series isetyenzisiwe, ii-gaskets eziqhelekileyo ze-flange zingalungiswa.
