Flange (onani flange JBZQ 4187-97) imatchedwanso flange kapena flange.Zigawo zomwe zimagwirizanitsa chitoliro ndi chitoliro kwa wina ndi mzake, zomwe zimamangiriridwa ku malekezero a chitoliro.Pali mabowo mu flange, ndipo mabawuti amalumikiza mwamphamvu ma flanges awiri.Ma flanges amasindikizidwa ndi gaskets.Kuyika kwa mapaipi a Flange kumatanthawuza zopangira mapaipi okhala ndi ma flanges (flanges kapena minda).Ikhoza kuponyedwa, kupukuta kapena kuwotcherera.
Kulumikizana kwa flange (flange, olowa) kumakhala ndi ma flanges, gasket ndi mabawuti angapo ndi mtedza.Gasket imayikidwa pakati pa malo osindikizira a flanges awiri.Pambuyo pomangika mtedza, kuthamanga kwapadera pamtunda wa gasket kumafika pamtengo wina kenako kumapunduka, ndikudzaza kusagwirizana pamtunda wosindikiza kuti kugwirizanako kukhale kolimba.Kulumikizana kwa Flange ndi kulumikizana komwe kumatha.Malinga ndi magawo olumikizidwa, imatha kugawidwa mu chidebe cha flange ndi chitoliro cha chitoliro.Malinga ndi kapangidwe kake, pali flange yophatikizika, loop flange ndi flange yolumikizidwa.Ma flanges ophatikizika ambiri amaphatikizanso ma flanges owotcherera ndi matako.Zowotcherera zathyathyathya zimakhala zosakhazikika bwino ndipo ndizoyenera nthawi zomwe kuponderezedwa kwa p≤4MPa.matako kuwotcherera flanges, omwe amadziwikanso kuti high khosi flanges, ali olimba kwambiri ndipo ndi oyenera nthawi ndi kuthamanga kwambiri ndi kutentha.
Pali mitundu itatu ya malo osindikizira a flange: malo osindikizira athyathyathya, oyenerera nthawi zokhala ndi mphamvu yotsika komanso sing'anga yopanda poizoni.Pamwamba pa concave-convex kusindikiza, yoyenera nthawi zokhala ndi kupanikizika pang'ono, zofalitsa zapoizoni komanso nthawi zothamanga kwambiri.Gasket ndi mphete yopangidwa ndi zinthu zomwe zimatha kutulutsa pulasitiki ndipo zimakhala ndi mphamvu.Ma gaskets ambiri amadulidwa kuchokera ku mbale zopanda zitsulo, kapena amapangidwa ndi mafakitale akatswiri malinga ndi kukula kwake.Zida zake ndi mbale za mphira wa asibesitosi, mbale za asibesitosi, mbale za polyethylene, ndi zina.Palinso gasket yovala zitsulo yopangidwa ndi zinthu zopanda zitsulo.palinso chilonda cha gasket chopangidwa ndi tizitsulo tating'onoting'ono tachitsulo ndi zingwe za asibesitosi.Ma gaskets wamba a rabara ndi oyenera nthawi zomwe kutentha kumakhala kotsika kuposa 120 ° C.Ma gaskets a mphira wa asbestos ndi oyenera nthawi zomwe kutentha kwa nthunzi wamadzi kumakhala kotsika kuposa 450 ° C, kutentha kwamafuta kumakhala kotsika kuposa 350 ° C, ndipo kupanikizika kumakhala kotsika kuposa 5MPa.Yapakatikati, yomwe imagwiritsidwa ntchito kwambiri ndi board ya asibesitosi yosamva acid.Pazida zothamanga kwambiri komanso mapaipi, ma gaskets opangidwa ndi lens kapena mawonekedwe ena opangidwa ndi mkuwa, aluminiyamu, No. 10 zitsulo, ndi zitsulo zosapanga dzimbiri zimagwiritsidwa ntchito.Kulumikizana m'lifupi pakati pa high-pressure gasket ndi kusindikiza pamwamba ndi yopapatiza kwambiri (kukhudzana kwa mzere), ndipo mapeto a processing of kusindikiza pamwamba ndi gasket ndi apamwamba.
Gulu la Flange: Ma Flanges amagawidwa kukhala ma flanges (mawaya) ndi zowotcherera.The low-pressure ang'onoang'ono awiri ali ndi waya flange, ndi mkulu-pressure ndi otsika-kupanikizika lalikulu diameters ntchito kuwotcherera flanges.Makulidwe a mbale ya flange ya zovuta zosiyanasiyana ndi m'mimba mwake ndi kuchuluka kwa mabawuti olumikizira ndizosiyana.Malingana ndi mitundu yosiyanasiyana ya kupanikizika, mapepala a flange amakhalanso ndi zipangizo zosiyana, kuyambira pazitsulo zotsika kwambiri za asbesitosi, mapepala a asbestos othamanga kwambiri mpaka zitsulo zachitsulo.
1. Amagawidwa ndi zinthu kukhala carbon zitsulo, zitsulo, aloyi zitsulo, zitsulo zosapanga dzimbiri, mkuwa, zotayidwa aloyi, pulasitiki, argon, ppc, etc.
2. Malingana ndi njira yopangira, ikhoza kugawidwa m'mapangidwe opangidwa ndi flange, flange, kuwotcherera flange, flange yopukutira (chitsanzo chachikulu) 3. Malinga ndi ndondomeko yopangira, ikhoza kugawidwa muyeso ya dziko (muyezo wa Ministry of Chemical). Makampani, muyezo wa petroleum, muyezo wamagetsi amagetsi), American Standard, German Standard, Japanese Standard, Russian Standard, etc.
Machitidwe angapo a International pipe flange miyezo:
1. Kulumikizana kwa flange kapena kuphatikizika kwa flange kumatanthawuza kulumikizana kopindika komwe kumakhala ndi ma flanges, ma gaskets ndi mabawuti olumikizidwa wina ndi mnzake ngati chosindikizira chophatikizana.Mapaipi a mapaipi amatanthawuza ma flange omwe amagwiritsidwa ntchito popanga mapaipi pakuyika mapaipi.Pazida, zimatanthawuza zolowera ndi zotuluka za zida.
