[Flange Gate Valve] NORTECH mtundu wa Quality assurance, NORTECH VALVE imayambitsa momveka bwino miyezo yoyenera, kusankha kwamtundu, ntchito, zojambula zamapangidwe, mawonekedwe ndi chitsanzo cha valve yachipata cha flange;Mulingo wonse, mfundo yogwirira ntchito, buku lazamankhwala, kukhazikitsa ndi kukonza ndi chithunzi cha schematic;Apatseni ogwiritsa ntchito mndandanda wa mavavu a chipata cha flange okhala ndi mawonekedwe apamwamba, magwiridwe antchito apamwamba, muyezo wapamwamba, moyo wautumiki wapamwamba komanso mtengo wokonda.
Kufotokozera kwa valavu ya chipata cha flange:
Flange chipata valavu ntchito mwadzina kuthamanga PN1 Kudula kapena kulumikiza sing'anga payipi pa mapaipi a kachitidwe zosiyanasiyana mafuta mafuta, mankhwala, hayidiroliki ndi matenthedwe zomera ndi kutentha ntchito 6 ~ 16.0mpa ndi kutentha ntchito ≤ - 29 ℃ ~ 550 ℃.The zofalitsa ntchito flange chipata valavu ndi: madzi, mafuta, nthunzi, asidi, alkali, ammonia, urea, sulfure munali gasi, etc. mode ntchito ndi: Buku, galimoto galimoto, magetsi, pneumatic, etc.
Mapangidwe a valavu ya chipata cha flange:
1. Kusankhidwa kwa zinthu zabwino kwambiri, mogwirizana ndi zofunikira zapakhomo ndi zakunja, kapangidwe koyenera komanso mawonekedwe okongola.2. Malo osindikizira a valve disc ndi mpando wa valve amapangidwa ndi iron-based alloy surfacing kapena Stellite cobalt based cemented carbide pamwamba.Imakhala ndi kukana kwabwino kovala, kukana kutentha kwambiri, kukana dzimbiri, kukana zikande komanso moyo wautali wautumiki.3. Ndodo ya valavu imakhala ndi kukana kwa dzimbiri komanso kukana kukanika pambuyo pozimitsa ndi kutentha ndi chithandizo cha nitriding pamwamba.4. Miyezo yosiyana siyana ya piping flange ndi mitundu yosindikizira ya flange imatha kutengedwa kuti ikwaniritse zosowa zaumisiri ndi zofunikira za ogwiritsa ntchito.5. Thupi la valve liri ndi zipangizo zosiyanasiyana, ndipo kulongedza ndi gasket kungasankhidwe moyenerera malinga ndi momwe ntchitoyo ikugwirira ntchito kapena zofunikira za ogwiritsa ntchito, zomwe zingagwiritsidwe ntchito pazovuta zosiyanasiyana, kutentha ndi ntchito zapakati.6. The inverted chisindikizo amapangidwa ndi ulusi kugwirizana chisindikizo mpando kapena thupi surfacing austenitic zitsulo zosapanga dzimbiri.Chisindikizocho ndi chodalirika.Kusintha kwa filler kumatha kuchitika popanda kutseka, komwe kuli kosavuta komanso kwachangu komanso sikukhudza magwiridwe antchito.
Kufotokozera kwa valavu ya chipata cha flange:
Ma valve a chipata cha Flange amagwiritsidwa ntchito kwambiri pagulu lazinthu.Vavu yachipata imatengera mawonekedwe otsetsereka a 5-degree ndikusindikiza bwino.Malo osindikizira a valavu yachipata ndi mpando wa valve amapangidwa ndi Stellite cobalt yochokera ku carbide ya simenti yokhala ndi kuuma kosiyana.Amakhala ndi kusindikiza kodalirika, kuuma kwakukulu, kukana kuvala, kukana kutentha kwambiri, kukana kwa dzimbiri, kukana kukanda bwino komanso moyo wautali wautumiki.Ma valve a zipata za Flange amagwiritsidwa ntchito kwambiri m'makampani a petrochemical, malo opangira magetsi otentha ndi zinthu zina zamafuta.

NORTECH ndi m'modzi mwa opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
