Xov Flange

Flange tseem hu ua flange lossis flange.

Ib feem uas txuas cov yeeb nkab thiab cov yeeb nkab rau ib leeg yog txuas mus rau qhov kawg ntawm cov yeeb nkab. Muaj qhov ntawm lub flanges, thiab bolts ua rau ob lub flanges nruj nreem txuas. Cov flanges yog kaw nrog gaskets. Flanged yeeb nkab fittings xa mus rau cov yeeb nkab fittings nrog flanges (lugs lossis sockets). Nws tuaj yeem ua los ntawm casting (tsis muaj nyob hauv daim duab), los yog nws tuaj yeem tsim los ntawm kev sib txuas threaded lossis vuam. Flange kev twb kev txuas (flange, sib koom ua ke) muaj ob lub flanges, gasket thiab ob peb bolts thiab ceev. Lub gasket yog muab tso rau ntawm lub sealing nto ntawm ob flanges. Tom qab zawm cov txiv ntseej, lub siab tshwj xeeb ntawm lub gasket nto mus txog ib qho txiaj ntsig thiab deforms thiab ua rau qhov tsis sib xws ntawm lub sealing nto kom cov kev sib txuas nruj thiab cov ntaub ntawv pov thawj. Flange kev twb kev txuas yog ib tug detachable kev twb kev txuas. Raws li cov khoom sib txuas, nws tuaj yeem muab faib ua lub thawv flange thiab cov yeeb nkab flange. Raws li hom qauv, muaj cov flanges ib leeg, xoob flanges thiab threaded flanges. Feem ntau cov flanges muaj xws li tiaj vuam flanges thiab taub qab vuam flanges. Flat-welded flanges muaj qhov tsis zoo rigidity thiab haum rau lub sijhawm nrog siab p≤4MPa; taub qab-welded flanges tseem hu ua high-caj dab flanges nrog ntau dua rigidity thiab haum rau lub sij hawm uas siab dua thiab kub. Muaj peb hom flange sealing nto: tiaj sealing nto, haum rau lub sijhawm uas tsis tshua muaj siab thiab tsis muaj tshuaj lom; concave-convex sealing nto, haum rau lub sijhawm nrog me ntsis siab dua; tus nplaig thiab zawj sealing nto, haum rau cov nplaim taws thiab tawg, Cov tshuaj lom neeg thiab lub sijhawm siab. Lub gasket yog lub nplhaib ncig ua los ntawm cov khoom siv uas tuaj yeem tsim cov yas deformation thiab muaj qee lub zog. Feem ntau ntawm cov gaskets raug txiav los ntawm cov hlau tsis yog hlau, los yog ua los ntawm cov chaw tsim khoom raws li qhov loj me. Cov ntaub ntawv yog asbestos roj hmab daim hlau, asbestos daim hlau, polyethylene daim hlau, thiab lwm yam.; nyias hlau daim hlau (dawb hlau, stainless hlau) kuj yog siv los tshem tawm cov asbestos A hlau qhwv gasket ua los ntawm cov khoom tsis yog xim hlau; kuj tseem muaj cov kauv qhov txhab gasket ua los ntawm nyias steel daim kab xev thiab asbestos daim kab xev. Cov roj hmab zoo tib yam yog tsim rau lub sijhawm uas qhov kub thiab txias qis dua 120 ° C; Asbestos roj hmab gaskets yog tsim rau lub sijhawm uas qhov kub ntawm cov dej vapor qis dua 450 ° C, qhov kub ntawm cov roj yog qis dua 350 ° C, thiab lub siab yog qis dua 5MPa, thiab nws feem ntau corrosive. Qhov feem ntau siv nruab nrab yog acid-resistant asbestos board. Hauv cov khoom siv hluav taws xob siab thiab cov kav dej, cov hlau gaskets ntawm lub lens hom lossis lwm cov duab ua los ntawm tooj liab, aluminium, No. 10 steel, thiab stainless hlau yog siv. Kev sib cuag dav ntawm lub siab-siab gasket thiab sealing nto yog nqaim heev (kab sib cuag), thiab kev ua tiav ntawm sealing nto thiab lub gasket yog siab heev.

Lub flange muab faib ua threaded kev twb kev txuas (xov hlau txuas) flange, vuam flange thiab clamping flange. Muaj cov hlau flanges thiab ferrule flanges rau qis-siab me me diameters. Welded flanges yog siv rau high-pressure thiab low-pressure loj diameters. Lub thickness ntawm flanges thiab txoj kab uas hla thiab tus naj npawb ntawm kev sib txuas bolts yog txawv rau qhov sib txawv.
