Lub Tilted Disc Check Valve yog qhov kev xaiv zoo tshaj plaws rau cov dej nyoos, dej txias thiab kev siv dej / dej khib nyiab. Nws streamlined lub cev contouring, ntws cheeb tsam 40% ntau dua nominal yeeb nkab loj thiab hydrodynamic disc ua ke los muab lub taub hau poob qis tshaj ntawm ib qho kos valve tsim hnub no.
Thaum tilting disc kos li qub yog siv rau dej hiav txwv lossis cov txheej txheem dej, cov khoom siv SS duplex yog qhov kev xaiv zoo tshaj plaws los txhim kho nws cov kev ua tau zoo.
Cov khoom ntawm duplex stainless hlau cov ncauj lus kom ntxaws specification raws li hauv qab no.
CE3MN (SS2507) Super Duplex Stainless Hlau
CE3MN (UNS S32750), yog super duplex stainless hlau, nrog ntau dua corrosive tsis kam tshaj tus qauv Ss2205and 18-8 Cr-Ni thiab 18-14-2 / 18-14-3 Cr-Ni-Mo stainless hlau qhov chaw, feem ntau yog siv rau kev pabcuam nyob rau hauv corrosive tej yam kev mob.
Casting Material Standard: ASTM A890 thiab ASTM A995 Qib 5A: Hom 25Cr-7Ni-Mo-N; Casting UNSJ93404; ACI CE3MN;
Lwm cov qib hlau zoo sib xws hauv daim ntawv thov sib txawv A789 / ASTM A790 / ASTM A276:

ASTM A890/890M Standard Specification rau Castings, lron-Chromium-Nickel-Molybdenum Corrosion-Resistant, Duplex (Austenitic/Ferritic) rau General Applications A995/995M Standard Specification rau Castings, Austenitic-Ferritic (Duplex) Stainless Steel, Yam khoom
CE3MN Kev kho cua sov txheej txheem:
Thaum tshav kub kub mus rau 2050 ° F [1120 ° C] yam tsawg kawg nkaus, tuav kom txaus lub sij hawm kom sov casting rau qhov kub thiab txias, rauv txias rau 1910 ° F [1045 ° C] yam tsawg kawg nkaus, quench nyob rau hauv dej los yog ceev txias los ntawm lwm yam txhais tau tias.
Hardness ≤HB300 (HRC32
Dye penetrant tshuaj xyuas yog hom NDT xeem. Nws yog tshwj xeeb yog siv los nrhiav qhov chaw tsis xws luag, xws li cov kab nrib pleb, qhov porosity thiab xau hauv cov hlau. Nws yog nyob ntawm qhov muaj peev xwm ntawm cov kua uas tau kos rau hauv qhov tsis zoo los ntawm kev ua haujlwm capillary
Thaum lub sij hawm xeem txheej txheem, cov khoom yog dipped nyob rau hauv ib tug penetrant kua. Qhov no yog sab laug rau soak rau txog 30 feeb. Ib qho kev nkag siab ntau dhau yuav raug tshem tawm ua ntej tus tsim tawm dawb raug siv. Cov neeg tsim tawm no pab txhawm rau txhawm rau nkag mus los ntawm qhov tsis xws luag rau saum npoo thiab nthuav tawm txhua qhov tsis zoo - txheej txheem hu ua 'los ntshav tawm'.
Tom qab ib lub sij hawm luv luv, cov khoom raug tshuaj xyuas nyob rau hauv lub teeb ultraviolet. Txhua qhov tsis zoo yuav fluoresce ci ntsa iab hauv lub teeb no.
