Yintoni uQhagamshelwano lweFlange

Uxhulumaniso lweFlange, njengoko negama lisitsho, ludibaniso oludibanisa ngokuqinileyo iiflange ezimbini kuzo zombini iziphelo zombhobho.Olu luhlu lulula ukuchithwa kwaye lusebenza kakuhle ukutywinwa.

1 Yintoni uxhulumaniso lweflange
Uxhulumaniso lweFlange ngokwenene luhlobo lokudibanisa oludibanisa imibhobho enye kwenye, kwaye ikwayindlela yokudibanisa, ngokukodwa ngokulungisa izixhobo ezimbini zepayipi okanye iipayipi kwiiflange ezimbini ngokulandelelana, kwaye ke phakathi kweeflange ezimbini.Gcoba iwasha yeflange, kwaye ekugqibeleni uqinise iiflange ngeebholiti ukuze zihlangane ngokuqinileyo.Olu hlobo lokudibanisa phakathi kwemibhobho lusetyenziswa kakhulu kwimibhobho yentsimbi kunye nemibhobho enerabha.

2 Uqhagamshelwano lweFlange
Iindlela zokudityaniswa kwe-Flange ngokubanzi zinokwahlulwa zibe ziindidi ezintlanu: i-flat welding, i-butt welding, i-socket welding, i-sleeve ekhululekile kunye nentambo.
Ezokuqala ezine zichazwe ngokweenkcukacha ngezantsi:
I-Flat welding: kuphela uluhlu lwangaphandle oludibeneyo, kwaye uluhlu lwangaphakathi alufunwa;isetyenziswa ngokubanzi kwimibhobho yoxinzelelo oluphakathi kunye noluphantsi, kwaye uxinzelelo lwegama lombhobho kufuneka lube ngaphantsi kwe-2.5MPa.Kukho iintlobo ezintathu zemigangatho yokutywina yeeflange zokuwelda ezisicaba, ezizezi, uhlobo olugudileyo, uhlobo lweconcave-convex kunye nolwimi-and-groove.Phakathi kwabo, uhlobo olugudileyo lolona lusetyenziswa kakhulu, kwaye luyafikeleleka kwaye lunendleko.
Ukuwelda iimpundu: amaleko angaphakathi nangaphandle eflange kufuneka adityaniswe, asetyenziswe ngokubanzi kwimibhobho yoxinzelelo oluphakathi kunye nophezulu, kwaye uxinzelelo lwegama lombhobho luphakathi kwe-0.25 kunye ne-2.5MPa.Umphezulu wokutywina wendlela yokudibanisa i-butt welding flange i-concave kunye ne-convex, kwaye ukufakela kuyinkimbinkimbi, ngoko iindleko zabasebenzi, indlela yokufakela kunye neendleko zempahla ezincedisayo ziphezulu kakhulu.
I-Socket welding: isetyenziswa ngokubanzi kwimibhobho enoxinzelelo lwegama olungaphantsi okanye olulingana no-10.0MPa kunye nedayamitha ephantsi okanye elingana ne-40mm.
Umkhono okhululekileyo: osetyenziswa ngokubanzi kwimibhobho enoxinzelelo oluphantsi kodwa uphakathi ekutyaleni, ngoko ke olu hlobo lweflange lunokumelana ne-corrosion eyomeleleyo, kwaye imathiriyeli ubukhulu becala yintsimbi engatyiwayo.

3 Inkqubo yoqhagamshelwano lweFlange
Inkqubo yoqhagamshelo lweflange imi ngolu hlobo lulandelayo:
Okokuqala, ukudibanisa phakathi kwe-flange kunye nombhobho kufuneka kuhlangabezane nezi mfuno zilandelayo:
1. Iziko lombhobho kunye neflange kufuneka libe kumgca othe tye.
2. Umbindi wombhobho kunye nomgangatho wokutywinwa we-flange wenza i-90-degree-vertical shape.
3. Isikhundla se-flange bolts kumbhobho kufuneka sibe yinto efanayo.

Okwesibini, i-padding flange gasket, iimfuno zezi zilandelayo:
1.Kumbhobho ofanayo, ii-gaskets ezikhethiweyo kwiiflange ezinoxinzelelo olufanayo kufuneka zifane, ukwenzela ukuba kube lula ukutshintshiselana kwixesha elizayo.
2. Kwimibhobho esebenzisa i-rubber sheets, kungcono ukhethe i-rubber gaskets, njengemizila yamanzi.
3. Umgaqo wokhetho we-gasket ngulo: khetha ngokusondeleyo kangangoko kunokwenzeka kububanzi obuncinci, obungumgaqo omele ulandelwe kwisiseko sokuba i-gasket ayiyi kutyunyuzwa.

Okwesithathu, i-flange yokudibanisa
1. Khangela ukuba ngaba iinkcukacha zeeflange, iibholithi kunye neegaskets ziyahlangabezana neemfuno.
2. Umphezulu wokutywina kufuneka ugcinwe ugudile kwaye ucocekile ngaphandle kwee-burrs.
3. Umtya we-bolt kufuneka uphelele, kungabikho ziphene, kwaye ukulungelelaniswa kufuneka kube yindalo.
4. I-texture ye-gasket kufuneka iguquguquke, ingabi lula ukuguga, kwaye umphezulu akufanele wonakaliswe, imibimbi, i-scratches kunye nezinye iziphene.
5. Ngaphambi kokudibanisa i-flange, i-flange kufuneka ihlambuluke ukuze isuse ioli, uthuli, i-rust kunye nezinye ii-sundries, kwaye umgca wokutywina kufuneka ususwe ngokucocekileyo.

Okwesine, i-flange yendibano
1. Indawo yokutywinwa kwe-flange i-perpendicular kumbindi wombhobho.
2. Iibholiti zenkcazo efanayo zinendlela efanayo yokufakela.
3. Indawo yokufakela i-flange efakwe kumbhobho wesebe kufuneka ibe ngaphezu kwe-100 mm ukusuka eludongeni lwangaphandle lokunyuka, kwaye umgama ovela eludongeni lwesakhiwo kufuneka ube ngu-200 mm okanye ngaphezulu.
4. Musa ukungcwaba i-flange ngqo phantsi komhlaba, kulula ukuba i-corrode.Ukuba kufuneka ingcwatywe phantsi komhlaba, kuyimfuneko ukwenza unyango oluchasene nokubola.
