Wopanga Duplex A182 F60 Chipata Valve

Vavu yachipata chachitsulo chopangidwa ndi valavu yomwe chipata chake chimayenda molunjika pakatikati pa ndimeyo. Mavavu achitsulo opangidwa ndi zipata amagwiritsidwa ntchito kwambiri podula mapaipi. Vavu yachipata chopangidwa ndi chitsulo ndi valavu yomwe imagwiritsidwa ntchito kwambiri, ndipo imagwiritsidwa ntchito podulira zida zokhala ndi DN ≤ 50. Mavavu achitsulo opangidwa ndi chitsulo ndiofala kwambiri.

Chitsulo chosapanga dzimbiri cha Duplex ndi chitsulo chosapanga dzimbiri chomwe theka la gawo la ferrite ndi theka la gawo la austenite lilipo mumayendedwe ake ozizimitsa, okhala ndi gawo lochepa la 30%. Chitsulo chosapanga dzimbiri cha Duplex chimapangidwa powonjezera Cr kapena kuwonjezera zinthu zina za ferrite pamaziko a 18-8 austenitic chitsulo chosapanga dzimbiri. Sikuti ali ndi bi-directional dongosolo la austenite ndi ferrite, komanso amapulumutsa Ni aloyi. Chifukwa cha mawonekedwe a magawo awiri a chitsulo chosapanga dzimbiri cha duplex, powongolera moyenera kapangidwe ka mankhwala ndi njira yochizira kutentha, chitsulo chosapanga dzimbiri cha duplex chimatha kuphatikiza zabwino za chitsulo chosapanga dzimbiri cha ferritic ndi chitsulo chosapanga dzimbiri cha austenitic. Kukhalapo kwa austenite mu zitsulo zosapanga dzimbiri zosapanga dzimbiri kumachepetsa kuwonongeka kwa Cr ferrite komanso chizolowezi chakukula kwa kristalo, ndikusunga kulimba kwambiri ndi kuwotcherera; Kukhalapo kwa ferrite kumawonjezera zokolola mphamvu, kukana intergranular dzimbiri, ndi kukana kolorayidi nkhawa dzimbiri za austenite.
