Li-flanges ke lisebelisoa tsa liphaephe tse atisang ho sebelisoa ho hokahanya liphaephe le liphaephe kapa ho hokahanya lisebelisoa tse peli tsamaisong ea liphaephe. Ho na le mefuta e mengata eali-flange,joalo kali-flange tse khoele, tjheseletsa molala flanges, li-flange tsa ho tjheseletsa poleiti, joalo-joalo (ka kakaretso e bitsoa li-flange). Leha ho le joalo, bophelong ba sebele, u ka boela ua hlokomela hore ho na le sehlahisoa se seng sa flange se bitsoang blind flange. Phapang ke efe pakeng tsa flange e tloaelehileng le foufalitsoeng e foufetseng? Joang ho kenya le ho sebelisa foufetseng flange?
1. Phapang pakeng tsa flange le blind flange
(1) Ho na le masoba holim'a flange. Nakong ea ho hokahanya, li-flange tse peli li hloka ho kenngoa ka li-bolts. Flange e tiisitsoe ka li-gaskets ho bapala karolo ea ho tiisa, kapa ho bapala karolo ea nakoana tekong;
The foufetseng flange e entsoe ka ho lahla kapa khoele khoele kapa tjheseletsa. Ke flange e se nang masoba bohareng. Haholo-holo e sebelisetsoa ho tiisa ntlha e ka pele ea phala, le ho tiisa orifice ea pipe. Mosebetsi oa eona o tšoana le oa hlooho le sekoahelo sa phala, 'me o bapala karolo ea ho itšehla thajana le ho itšeha. Leha ho le joalo, tiiso ea foufetseng ea flange ke sesebelisoa sa ho tiisa se tlosoang. Tiiso ya hlooho ha eso lokele ho bulwa hape. Flange e foufetseng e ka tlosoa ho thusa ho sebelisoa hape ha phala nakong e tlang.
(2) Hobane flange e na le litšobotsi tse ntle tsa ts'ebetso, hangata e sebelisoa haholo ho boenjiniere ba lik'hemik'hale, kaho, peterole, tsamaiso ea likhoerekhoere, lipeipi, ts'ireletso ea mollo le merero e meng ea motheo;
Hoa hlokahala ho beha lipoleiti tse foufetseng ha ho kopanngoa lisebelisoa le liphaephe, haholo-holo sebakeng sa moeli ka ntle ho sebaka sa moeli moo liphaephe tse fapaneng tsa lisebelisoa tsa ts'ebetso li kopantsoeng. Leha ho le joalo, tekong ea matla a liphaephe kapa teko ea ho tiisa, ha hoa lumelloa ho sebelisa lipoleiti tse foufetseng ka nako e le 'ngoe le lisebelisoa tse kopanyang (tse kang turbine, compressor, gasifier, reactor, joalo-joalo) sethaleng sa pele sa ho lokisetsa ho qala.
Empa ha e le hantle, ho na le lintho tse ngata tse tšoanang pakeng tsa li-flange le lipoleiti tse foufetseng tsa flange. Ka mohlala, ho na le mefuta e mengata ea libaka tsa ho tiisa, tse kang sefofane, convex, concave le convex, tenon le groove, le libaka tsa ho hokahanya ha mehele; E sebelisoa bakeng sa ho hokahanya ha flange, e nang le para ea flanges, gasket le liboutu tse 'maloa le linate. Gasket e behiloe pakeng tsa libaka tse peli tse tiisitsoeng tsa flange. Ka mor'a ho tiisa linate, khatello e khethehileng holim'a gasket e fihla ho boleng bo itseng, e leng ho tla etsa hore ho be le deformation, 'me likarolo tse sa tsitsang holim'a ho tiisa holim'a metsi li tla tlatsoa ho etsa hore ho be thata ho kopanya.
2. Ho kenya le ho sebelisoa ha flange blind plate
Letlapa le foufetseng la flange le ka boela la kopanngoa ke flange, ke hore, gasket e behoa pakeng tsa libaka tse peli tsa ho tiisa li-flange. Ka mor'a hore linate li tiisetsoe, khatello e khethehileng holim'a gasket e fihla boleng bo itseng, 'me ho hlaha deformation,' me libaka tse sa tsitsang holim'a sebaka sa ho tiisa li tlatsitsoe, e le hore ho amana ho be thata. Leha ho le joalo, poleiti e foufetseng ea flange e nang le khatello e fapaneng e na le botenya bo fapaneng 'me e sebelisa liboutu tse fapaneng; Tabeng ea tsamaiso ea oli ea oli, poleiti e foufetseng ea flange ha e hloke ho etsoa ka masenke, empa tabeng ea litsamaiso tse ling tse mahareng, poleiti e foufetseng ea flange e tla ba tlas'a phekolo e chesang ea galvanizing, boima bo fokolang ba ho roala zinki ke 610g / m2. , 'me boleng ba poleiti e foufetseng ea flange ka mor'a ho futhumatsa e chesang e tla hlahlojoa ho latela maemo a naha.
E ka holimo ke phapang pakeng tsa flange le foufalitsoeng ea foufetseng le ho kenya le ho sebelisoa ha foufetseng flange. Ke tšepa hore e ka u thusa ho khetha le ho kenya flange ka nepo le ho bapala karolo ea eona ea ho tiisa.
