Flange (sae flange JBZQ 4187-97) waxa kale oo loo yaqaan flange ama flange.Qeybaha isku xira tuubooyinka tuubooyinka midba midka kale, oo ku xiran darafyada tuubooyinka.Daloolo baa ku yaal garabka, boolalkuna waxay si adag ugu xidhaan labada garab.Garabyada waxaa lagu xidhay gaasaska.Xirmooyinka tuubooyinka caleenta waxay tixraacaan tuubooyinka dhejiska leh ee leh geesaha (qararka ama dhulka).Waa la tuuri karaa, la maroojin karaa ama la alxan karaa.
Isku xirka caleenta (flange, wadajir) wuxuu ka kooban yahay labo garab, gaas iyo dhowr boolal iyo lows.Gaaska waxa la dhigayaa inta u dhaxaysa meelaha daboolaya ee labada garab.Ka dib markii lawska la adkeeyo, cadaadiska gaarka ah ee dusha sare ee gasketku wuxuu gaaraa qiimo gaar ah ka dibna wuu qallafsan yahay, wuxuuna buuxiyaa sinnaan la'aanta dusha daboolka si uu xiriirku u adkeeyo.Xidhiidhka Flange waa xidhiidh la go'i karo.Marka loo eego qaybaha ku xiran, waxaa loo qaybin karaa flange weel iyo flange tuubooyinka.Marka loo eego nooca qaab-dhismeedku, waxaa jira flange isku dhafan, flange loop iyo flange dunsan.Garabyada alxanka ee caadiga ah waxaa ka mid ah garabyada alxanka fidsan iyo dabada alxanka.Albaabada alxanka fidsan waxay leeyihiin adayg liidata waxayna ku haboon yihiin waqtiyada cadaadiska p≤4MPa.dabada alxanka, sidoo kale loo yaqaan flanges luqunta sare, waxay leeyihiin adayg sare oo ku haboon xaaladaha cadaadis sare iyo heerkulka.
Waxaa jira saddex nooc oo dusha daboolida flange: dusha daboolida siman, oo ku habboon waqtiyada cadaadiska hooseeya iyo dhexdhexaad aan sun ahayn.dusha daboolida concave-convex, oo ku habboon waqtiyada leh cadaadis wax yar ka sarreeya, warbaahinta sunta ah iyo marmar cadaadis sare.Gaasku waa giraan ka samaysan shay soo saari kara qallafsanaanta balaastiigga ah oo leh awood gaar ah.Inta badan gaasaska waxaa laga gooyaa taarikada aan biraha ahayn, ama ay sameeyaan warshado xirfad leh iyadoo loo eegayo cabbirka la cayimay.Maaddooyinka waa taarikada caagga ah ee asbestos, taarikada asbestos, taarikada polyetylen, iwm.Waxa kale oo jira gaas bir ah oo ka samaysan waxyaabo aan bir ahayn oo duuban.Waxa kale oo jira gaas boog ah oo ka samaysan bir khafiif ah iyo xariijimo asbestos ah.Baakadaha caagga ah ee caadiga ah waxay ku habboon yihiin waqtiyada heerkulku ka hooseeyo 120 ° C.Gaasaska caagga ah ee asbestos waxay ku habboon yihiin waqtiyada heerkulka uumiga biyuhu uu ka hooseeyo 450°C, heerkulka saliidda uu ka hooseeyo 350°C, cadaadiskuna uu ka hooseeyo 5MPa.Dhexdhexaad, inta badan la isticmaalo waa looxa asbestos u adkaysta.Qalabka cadaadiska sare leh iyo dhuumaha, gaasaska birta ah ee lens-qaabeeya ama qaab kale oo ka samaysan naxaas, aluminium, No. 10 birta, iyo birta ah ayaa loo isticmaalaa.Ballaca xiriirka u dhexeeya gaasaska-cadaadiska sare iyo dusha shaabadeynta waa mid aad u cidhiidhi ah (xidhiidh khadka), iyo dhamaystirka processing ee dusha shaabadeynta iyo gasket waa xad sare.
Kala-soocidda Flange: Flanges waxay u qaybsamaan garabyo dunta ka xidhan iyo alxanka.Dhexroorka yar-yar ee cadaadiska hooseeya wuxuu leeyahay xargaha xargaha, iyo cadaadiska sare iyo cadaadiska hoose ee dhexroorka waaweyn waxay isticmaalaan flanges alxanka.Dhumucda saxanka flange ee cadaadisyo kala duwan iyo dhexroorka iyo tirada boolalka isku xira ayaa kala duwan.Sida laga soo xigtay heerarka kala duwan ee cadaadiska, suufka flange sidoo kale waxay leeyihiin walxo kala duwan, oo u dhexeeya sariiraha asbestos-ka cadaadiska hooseeya, suufka asbestos-ka-sare ilaa birta.
1. Waxaa loo qaybiyaa walxo bir kaarboon ah, birta la tuuray, birta daawaha, birta aan lahayn, copper, aluminium alloy, caag, argon, ppc, iwm.
2. Marka loo eego habka wax-soo-saarka, waxa loo qaybin karaa flange foorjari ah, flange shub ah, flange alxanka, garabka duuban ( model oversized) Warshadaha, heerka batroolka, heerka korantada) , Halbeegga Ameerikaanka, Halbeegga Jarmalka, Halbeegga Jabbaan, Heerka Ruushka, iwm.
Nidaamyo dhowr ah oo heerarka flange tuubooyinka caalamiga ah:
1. Xidhiidhka caleenta ama isku dhafka flange waxaa loola jeedaa isku xirka laalaabi karo ee ka kooban flanges, gaskets iyo boolal isku xiran oo midba midka kale ku xiran yahay qaab-dhismeed isku dhafan.Qaybaha tuubooyinka waxay tixraacaan flanges loo isticmaalo tuubbooyinka rakibaadda dhuumaha.Qalabka, waxa ay tilmaamaysaa geesaha laga soo galo iyo ka soo baxa qalabka.
