Iivalvu zokujonga i-waferzikwabizwa ngokuba ziivalve zokubuyela umva, iivalve zokubuyela umva, kunye neevalvu zoxinzelelo lwasemva.Ezi ntlobo zeevalvu zivulwa ngokuzenzekelayo kwaye zivalwe ngamandla okwenziwa kukuhamba kwesixhobo ngokwaso kumbhobho, sohlobo lwevalve oluzenzekelayo.
I-valve yokukhangela ixhomekeke ekuhambeni kwe-medium ngokwayo kwaye ivule ngokuzenzekelayo kwaye ivale i-valve flap, esetyenziselwa ukuthintela i-valve ephakathi, eyaziwa ngokuba yi-valve yokujonga, i-valve yokujonga, i-valve backflow, kunye ne-valve yoxinzelelo lwangasemva.Ivalve yokutshekisha yeyohlobo lwevalve oluzenzekelayo, indima yayo ephambili kukuthintela ukubuya kweendaba, ukuthintela impompo kunye nokuqhuba ukuguqulwa kwemoto, kunye nokukhutshwa kwemithombo yeendaba.Iivalvu zokukhangela nazo zingasetyenziselwa ukunika uxinzelelo lunokunyuka lube ngaphezu koxinzelelo lwenkqubo yenkqubo yokuncedisa ukubonelela ngombhobho wokubonelela.Ivalve yokutshekisha inokwahlulwa ibe yivalve yokukhangela i-swing (ngokweziko lokujikeleza komxhuzulane) kunye nevalve yokukhangela i-lift (ehamba nge-axis).
Okokuqala, ukusetyenziswa kwe-clip-on check valve check valve efakwe kwinkqubo yokubhobhoza, indima yayo ephambili kukuthintela ukubuyisela umva kweendaba, i-valve yokukhangela luhlobo lwevalve oluzenzekelayo oluxhomekeke kuxinzelelo lweendaba ukuvula nokuvala.Ivalve yokujonga i-clamp ifanelekile kuxinzelelo lwegama PN1.0MPa ~ 42.0MPa, Class150 ~ 25000, idiameter yegama DN15 ~ 1200mm, NPS1/2 ~ 48, ubushushu bokusebenza -196 ~ 540 ℃ yemibhobho eyahlukeneyo, esetyenziselwa ukuthintela ukubuya kweendaba ngasemva.Ngokukhethwa kwezinto ezahlukeneyo, zingasetyenziswa emanzini, umphunga, ioli, i-nitric acid, i-acetic acid, i-media oxidizing enamandla kunye ne-uric acid kunye nezinye imidiya.
Izinto eziphambili zevalve yokukhangela i-wafer yi-carbon steel, i-low-temperature steel, i-duplex steel (SS2205 / SS2507), i-titanium alloy, i-aluminium bronze, i-Inconel, i-SS304, i-SS304L, i-SS316, i-SS316L, i-chrome-molybdenum steel, i-Monel (400 / 500), 20 # ingxubevange, Hastelloy kunye nezinye izinto zentsimbi.
Okwesithathu, imigangatho kunye nemimiselo yevalve yokujonga i-wafer
Uyilo:API594,API6D,JB/T89372,
Ubuso ngobuso ubude: API594, API6D,DIN3202,JB/T89373,

Okwesine, iimpawu zesakhiwo se-pinch check valve
1.Ubude obufutshane besakhiwo, ubude bayo besakhiwo buyi-1/4 ~ 1/8 kuphela yevalve yokujonga i-swing flange.
2. umthamo omncinci, ubunzima obukhanyayo, ubunzima bayo kuphela ivalve yesiqhelo yokujonga i-flange 1/4 ~ 1/2
3. i-valve flap ivala ngokukhawuleza, uxinzelelo lwehamile yamanzi luncinci
4. Umbhobho othe tyaba okanye othe nkqo ungasetyenziswa, kulula ukuyifaka
5. Indlela yokuhamba egudileyo, ukumelana nolwelo oluphantsi
6.Isenzo esibucayi, ukusebenza kakuhle kokutywinwa
I-7.I-Disc stroke imfutshane, impembelelo yokuvala incinci
I-8.Isakhiwo esipheleleyo silula kwaye sihlangene, kwaye imilo ihle
9. Ubomi benkonzo ende kunye nokusebenza okuthembekileyo
Ntlanu.Ukusebenza kokutywina kwevalve yokujonga i-wafer etywiniweyo Ivalve yokujonga i-wafer etywiniweyo ethambileyo inokufikelela ekuvuzeni kweqanda, kodwa ivalve yokukhangela i-wafer etywiniweyo ayisiyovalve yokuvuza enguziro.Inomlinganiselo othile wokuvuza.Ngokomgangatho wokuhlola we-API598, kwivalve yokutshekisha enesihlalo sesinyithi, ubungakanani be-DN100, umlinganiselo wokuvuza kwamanzi ngomzuzu ngu-12CC.
