IYINI I-FLANGE?ZINIZINHLOBO ZAMA-FLANGE?

I-flange iyirimu eqhumile noma unqenqema lwepayipi, i-valve, noma enye into, ngokuvamile esetshenziselwa ukukhulisa amandla noma ukusiza ukunamathiselwa kwamapayipi noma okokufakwayo.

I-Flange yaziwa nangokuthi i-flange convex disk noma ipuleti le-convex. Iyingxenye emise okwediski, ngokuvamile esetshenziswa ngababili.Isetshenziswa kakhulu phakathi kwepayipi nevalvu, phakathi kwepayipi nepayipi naphakathi kwepayipi nezinto zokusebenza, njll. Izingxenye ezixhumeka ngokuvala uphawu. Kunezinhlelo zokusebenza eziningi phakathi kwalezi zisetshenziswa kanye namapayipi, ngakho-ke izindiza ezimbili zixhunywe ngama-bolts, futhi izingxenye zokuxhuma ezinomphumela wokuvala zibizwa ngokuthi i-flange.

Ama-flange avame ukusetshenziswa ezinhlelweni zamapayipi ukuxhuma amapayipi, ama-valve, amaphampu, nezinye izinto zokusebenza. Bahlinzeka ngendlela yokuhlanganisa kalula nokuhlakazwa kwezingxenye, kanye nokuhlolwa, ukuguqulwa, noma ukuhlanzwa kwesistimu.

Ngokuvamile, kunezimbobo eziyindilinga ku-flange ukudlala indima engashintshi. Isibonelo, uma usebenzisa ekuhlanganyeleni kwepayipi, indandatho yokuvala yengezwa phakathi kwamapuleti amabili e-flange. Bese-ke ukuxhumana kuqiniswa ngamabhawodi. I-flange enengcindezi ehlukene inogqinsi oluhlukene namabhawodi ahlukene. Izinto eziyinhloko ezisetshenziselwa i-flange yi-carbon steel, insimbi engagqwali ne-alloy steel, njll.

Kunezinhlobo eziningana zeama-flange, ngayinye yakhelwe izinjongo ezithile. Nazi ezinye izinhlobo ezivamile zama-flange:

1. I-Weld Neck Flange (WN):Lolu hlobo lwe-flange lubonakala ngentamo ende, ecijile eshiselwe epayipini. Yenzelwe ukudlulisa ukucindezeleka kusuka ku-flange kuya kumbhobho, ukunciphisa ingozi yokuvuza.Weld intamo flangeszivame ukusetshenziselwa izicelo ezinengcindezi ephezulu kanye nezinga lokushisa eliphezulu.
2. I-Slip-On Flange (SO): Ama-Slip-on flangesabe nobubanzi obuthe ukudlula ipayipi, futhi ashibilika phezu kwepayipi bese eshiselwa endaweni. Kulula ukuziqondanisa futhi zifanele izicelo zokucindezela okuphansi. Kukhona olunye uhlobo lwe-flange olufana nalo, olubizwa ngokuthi i-plate flange. Umehluko phakathi kwalokhu okubili ulele ekubeni khona noma ukungabikho kwentamo, okudinga ukuhlukaniswa ngokuqinile.
3. I-Blind Flange (BL): Ama-flange ayimpumputhezingamadiski aqinile asetshenziselwa ukuvimba ipayipi noma ukwakha isitobhi ekupheleni kwepayipi. Azinayo imbobo ephakathi nendawo futhi zisetshenziselwa ukuvala ukuphela kwesistimu yamapayipi.
4. I-Socket Weld Flange (SW): Ama-socket weld flangesube nesokhethi noma isiphetho sesifazane esisetshenziselwa ukwamukela ipayipi. Ipayipi lifakwa kusokhethi bese lishiselwa endaweni yalo. Asetshenziselwa amapayipi amancane amancane kanye nezicelo zokucindezela okuphezulu.
5. I-Flange Enemicu (TH): Ama-flange anemicuabe nemicu endaweni engaphakathi, futhi asetshenziswa namapayipi anezintambo zangaphandle. Zifanele izicelo zokucindezela okuphansi.
6. I-Lap Joint Flange (LJ): Ama-flange ahlangene we-Lapasetshenziswa nge-stub end noma indandatho ehlangene ethangeni. I-flange ihanjiswa ngokukhululekile phezu kwepayipi bese kuthi indandatho ye-stub noma i-lap joint ring ishiselwe epayipini. Lolu hlobo lwe-flange luvumela ukuqondanisa kalula kwezimbobo ze-bolt.
