304 zitsulo zosapanga dzimbiri duplex zitsulo mkulu-anzanu anamanga zitsulo flange mpira valavu, PN63 kutentha kwambiri ndi kukana sulfure, malinga ndi mfundo dziko ndi America.

Stainless steel duplex steel high-pressure forged steel flange ball valve ndi valavu yapamwamba kwambiri yokhala ndi kutentha kwambiri, kukana sulfure, komanso kutsata mfundo za dziko ndi America. Amagwiritsidwa ntchito kwambiri m'mafakitale monga mankhwala, petroleum, ndi gasi wachilengedwe kuti azitha kuyendetsa madzimadzi komanso kuthamanga. Vavu ya mpira iyi imapangidwa ndi chitsulo chosapanga dzimbiri cha duplex chitsulo, chomwe chimakhala ndi mphamvu zambiri, kukana dzimbiri, komanso kukana kuvala. Malo ake osindikizira adachitidwa chithandizo chapadera kuti atsimikizire kusindikiza kwabwino komanso kupewa kutayikira. Pakadali pano, valavu ya mpira imakhalanso ndi maubwino amapangidwe osavuta, kukhazikitsa kosavuta, komanso kukonza kosavuta. Tebulo lofananiza kukula kwachitsanzo: |Model | dzina lake (DN) | kuthamanga kwa ntchito (MPa) | osiyanasiyana kutentha (℃) | njira yolumikizira | |-- | ------------------------------------------------------------------ -- -- --| | DQ41F | 15-150 | 1.6 | -29-300 | flange| | DQ341F | 25-300 | 2.5 | -29-300 | flange| | DQ61F | 40-400 | 4.0 | -29-300 | flange| | DQ941F | 50-600 | 6.4 | -29-300 | flange| | DQ641F | 80-900 | 10.0 | -29-300 | flange| Miyezo yomwe ili pamwambayi ndi yongofotokozera zokhazokha, ndipo kusankha kwapadera kuyenera kutsimikiziridwa malinga ndi momwe ntchito ikugwirira ntchito ndi zofunikira.
