The Tilted Disc Check Valve ndi chisankho chabwino kwambiri chamadzi osaphika, madzi ozizira komanso kugwiritsa ntchito madzi oyeretsedwa / madzi oyipa. Kuzungulira kwake kwa thupi, malo othamanga 40% aakulu kuposa kukula kwa chitoliro chodziwika bwino ndi hydrodynamic disc amaphatikizana kuti apereke kutaya kwapamutu kwa valve iliyonse yopangidwa lero.
Pamene tilting disc check valves amagwiritsidwa ntchito pamadzi a m'nyanja kapena madzi opangira madzi, duplex SS yakuthupi ndi yabwino kwambiri kuti ipititse patsogolo ntchito yake.
Zida za duplex zitsulo zosapanga dzimbiri mwatsatanetsatane monga pansipa.
CE3MN(SS2507) Super Duplex Stainless Steel
CE3MN (UNS S32750), ndi wapamwamba duplex zitsulo zosapanga dzimbiri, ndi kukana dzimbiri kuposa muyezo Ss2205ndi 18-8 Cr-Ni ndi 18-14-2/18-14-3 Cr-Ni-Mo zitsulo zosapanga dzimbiri mbali, makamaka ntchito ntchito m'mikhalidwe ya dzimbiri.

CE3MN Njira yochizira kutentha:
Kutentha mpaka 2050°F [1120°C] kucheperachepera, gwirani kwa nthaŵi yokwanira kuti kutentha kutenthe, ng'anjo izizire mpaka 1910°F [1045°C] osachepera, kuzimitsa m'madzi kapena kuzizirira mofulumira mwa njira zina.
Kuuma ≤HB300(HRC32
Kuwunika kolowera kwa utoto ndi mtundu wa mayeso a NDT. Amagwiritsidwa ntchito makamaka kuti apeze zolakwika zapamtunda, monga ming'alu, porosity ndi kutayikira kwazitsulo. Zimatengera kuthekera kwa madzi kuti akokedwe mu cholakwika ndi capillary action
Pakuyesa, chigawocho chimamizidwa mumadzi olowera. Izi zimasiyidwa kuti zilowerere mpaka mphindi 30. Kulowetsedwa kulikonse kumachotsedwa kusanakhazikitsidwe woyera. Wopanga izi amathandizira kutulutsa zomwe zili ndi zolakwika pamwamba ndikuwulula zolakwika zilizonse - njira yomwe imadziwika kuti 'kutulutsa magazi'.
Patapita nthawi yochepa, chigawocho chimayang'aniridwa ndi kuwala kwa ultraviolet. Kupanda ungwiro kulikonse kudzawala mowala mu kuwala uku.
