Chotsegula-ndodo / ndodo yakuda nodular cast iron flange gate valve ndi mtundu wazitsulo zachitsulo zopangidwa ndi valavu ya chipata cha flange, zokhala ndi mphamvu zambiri, kukana kuvala komanso kuchita bwino kwa zivomezi. Vavu yamtunduwu imagwiritsidwa ntchito kwambiri pamakina osiyanasiyana omanga, mafuta amafuta, makampani opanga mankhwala, chithandizo chamadzi ndi magawo ena kuti akwaniritse kudula, kufalitsa ndi kuwongolera mapaipi.
Open ndodo / mdima ndodo ductile chitsulo flange mavavu chipata monga DN250, DN300, DN400, DN500, DN600, DN700, DN800 ndi DN900 ndi makulidwe ena kukwaniritsa zosowa kugwirizana mapaipi osiyana. Njira yolumikizira valavu ndi kulumikizana kwa flange, komwe kumakhala kosavuta kukhazikitsa ndi kukonza.
Ndodo yotsegula ndi ndodo yakuda ndi njira ziwiri zogwirira ntchito za nodular cast iron flange gate valve. Kutsegula ndodo kumatanthawuza kuti kutsegula ndi kutseka kwa valavu kumachita mwachindunji pa tsinde la valve kupyolera mu gudumu lamanja, ndipo ntchitoyo ndi yophweka komanso yosavuta. Ntchito yobisika ya ndodo ndiyo kutembenuza kusuntha kwa gudumu la m'manja kupyolera mu mtedza wa tsinde la valve kukhala njira yowongoka ya tsinde la valve, kuti valavu itsegulidwe kapena kutsekedwa. Opaleshoni ya ndodo yakuda ndiyokhazikika kuposa ntchito yotseguka, yoyenera kuthamanga kwambiri, ma valve akulu awiri.
Kawirikawiri, ndodo yotseguka / ndodo yakuda ductile iron flange pachipata valavu ndi zinthu zake zabwino kwambiri zakuthupi ndi mitundu yosiyanasiyana ya kukula kwake, yomwe imagwiritsidwa ntchito kwambiri mumitundu yonse ya ntchito, kuti ikhale yotetezeka komanso yodalirika ya kayendedwe ka mapaipi imapereka chitsimikizo champhamvu.
