AWWA C207 ke tekanyetso ea li-flange tsa tšepe le li-flange tse foufetseng tse fanoeng ke American Water Works Association (AWWA).Tekanyetso ena e totobatsa litlhoko tsa boholo, thepa, tekanyo ea khatello, bophara ba lebitso, le sebopeho sa bokaholimo ba li-flange tsa tšepe le lipoleiti tse foufetseng.
AWWA C207 ha se maemo a machaba, empa ke maemo a naha ea Amerika (ANSI/AWWA C207).Leha ho le joalo, linaha le libaka tse ngata li amohetse maemo a AWWA C207 kapa mefuta e fapaneng ea ona e le maemo a lehae a tsona bakeng sa li-flange tsa tšepe le li-flange tse foufetseng.Mohlala, Canada, Australia, New Zealand, Mexico, le linaha tse ling tsa Middle East kaofela li sebelisa maemo a AWWA C207 kapa mefuta e fapaneng ea ona.

Thesephara se tjheseletsa se nang le molalaka mokhoa oa AWWA C207 ke khokahanyo ea tšepe ea tšepe, e tsejoang hape e le lesale la flange, le nang le sefahleho se chitja le molala oa cylindrical.Mofuta ona oa flange hangata o sebelisoa ho hokahanya liphaephe, li-valve, lipompo le lisebelisoa tse ling lits'ebetsong tsa hydraulic, liphaephe tsa metsi le lits'ebetso tse ling tse tsamaisang metsi.

Reite ea boholo le khatello:
Ho ea ka maemo a AWWA C207, bophara ba "diameter" ba li-welding flanges tsa molala bo tloha ho lisenthimithara tse 3 ho isa ho tse 144, 'me sekhahla sa likhatello se tloha ho liponto tse 150 ka lisekoere-inch ho isa ho liponto tse 2500 ka sekwere-inch.Mekhahlelo e kang bophara ba molala le botenya, botenya ba sefahleho sa flange, palo le bophara ba masoba a bolt, le mofuta le botenya ba li-gaskets tsa ho tiisa bakeng sa li-flange tse bataletseng tsa welding tse nang le melala le tsona li hlalositsoe ka mokhoa o tloaelehileng.
Empa tlhahisong ea 'nete, ka lebaka la litaba tsa lisebelisoa le lithibelo tsa lipalangoang tsa kantle ho naha, boholo ba tlhahiso ea nnete bo ka ba lisenthimithara tse 3 ho isa ho tse 72, e leng DN100 ho DN1800.

Kemiso:
Ho kenngoa hathella ka flangehangata ho hloka ho hokela bokaholimo ba flange ka liboutu le linate qetellong ea liphaephe, le ho tiisoa ka lipeipi ho etsa bonnete ba hore likhokahano tsa lipeipi li tiea le tse tiisang metsi.Mokhoa ona oa khokahano o na le melemo ea khokahano e bonolo, ts'epo e phahameng, le disassembly e matla, 'me e sebelisoa haholo lits'ebetsong tse fapaneng tsa liphaephe.

Papiso

Molala a bataletseng tjheseletsa flange le poleiti bataletseng tjheseletsa flange ke tse peli tse atisang ho sebelisoa tšepe flange dikgokelo, e lenge fapaneng hanyane ka sebopeho le tshebediso.Papiso pakeng tsa bona ke e latelang:

Sebopeho sa sebopeho: Molala o bataletseng oa tjheseletsa flange o na le molala oa cylindrical, ha mofuta oa poleiti o bataletseng oa ho cheselletsa flange ha o na molala mme o na le flange e bataletseng feela le gasket ea flange.

Sebaka sa ts'ebeliso: Li-flange tsa tjheseletsa tse nang le melala hangata li sebelisoa ho hokahanya liphaephe, li-valve, lipompo le lisebelisoa tse ling lits'ebetsong tsa hydraulic, liphaephe tsa metsi, le lisebelisoa tse ling tse tsamaisang metsi, athe li-flange tsa mofuta oa poleiti hangata li sebelisoa ho hokahanya liphaephe tse nyane le lisebelisoa. .

Khatello ea Khatello: Ka lebaka la molala o motenya le bokaholimo ba molala o bataletseng oa welding flange, hangata e khona ho mamella maemo a phahameng a khatello ho tloha ho liponto tse 150 ka sekwere-inch ho isa ho liponto tse 2500 ka lisenthimithara tse lisekoere.Li-flange tsa mofuta oa Plate tse bataletseng hangata li khona ho mamella likhatello tse tlase, ka sekhahla sa maemo a khatello ka tlase ho liponto tse 150 ka lisekoere-inch.

Mokhoa oa ho kenya: Li-flange tse nang le thamo tse bataletseng hangata li hloka tšebeliso ea liboutu le linate ho li hokela pheletsong ea liphaephe, ha li-flange tsa mofuta oa poleiti hangata li sebelisa li-gaskets le liboutu ho li hokela pheletsong ea liphaephe.Mekhoa ena ka bobeli e hloka taolo e tiileng ea torque ea khokahano le ho tiea.

Ka kakaretso, li-flange tsa welding tsa molala le li-flange tse nang le li-welding li na le ts'ebeliso e fapaneng lits'ebetsong le lisebelisoa tse fapaneng tsa liphaephe.Khetho ea lihokelo tse loketseng tsa flange e hloka ho khethoa ho ipapisitsoe le litlhoko tse ikhethileng tsa sistimi ea liphaephe le lisebelisoa.
