tus qauv ntawm flange kev twb kev txuas
Mechanism ua haujlwm:Los ntawm kev ceev cov bolts, lub gasket nruab nrab ntawm lub sealing nto ntawm lub flanges yog compressed thiab ua kom muaj zog, sau qhov tsis sib xws ntawm cov flange sealing nto. Cov txheej txheem no tiv thaiv qhov nruab nrab ntawm permeating los ntawm capillary pores nyob rau hauv lub gasket thiab to ntawm lub interface ntawm lub gasket thiab sealing nto, yog li ua tiav pre-sealing.
Cov xwm txheej los xyuas kom meej qhov xau-pov thawj flange txuas yog:Thaum lub sij hawm pre-tightening, lub pre-tightening quab yuam ua nyob rau hauv lub gasket yuav tsum tsis txhob qis tshaj lub pre-tightening sealing stress ratio, thiab thaum lub sij hawm ua hauj lwm, qhov seem ntawm kev nyuaj siab piv ntawm lub gasket yuav tsum tsis txhob qis dua qhov ua hauj lwm sealing stress ratio.
hom flanges
Raws li qib ntawm kev sib koom ua ke ntawm flanges thiab cov khoom siv lossis cov kav dej, kev sib txuas flange tuaj yeem muab faib ua pawg hauv qab no:
Fixed Flange txuas:Hauv hom kev sib txuas no, lub flange txuas mus tas li rau cov khoom siv lossis cov kav dej. Txoj kev sib txuas no tsim nyog rau cov xwm txheej uas tsis tas yuav tsum tau disassembly, xws li hauv cov kav dej mus tas li lossis cov khoom siv.
Slip-On Flange Connection:Txoj kev sib txuas no tso cai rau lub flange txav me ntsis thaum lub sij hawm sib dhos tab sis yog ruaj ruaj los ntawm bolts ib zaug txuas. Cov kev sib txuas flange no feem ntau yog siv hauv cov kav dej lossis cov khoom siv uas yuav tsum tau yooj yim disassembly.
Kev sib hloov Flange:Qhov kev sib txuas no tso cai rau lub flange tig mus rau ib qho degree thaum sib dhos. Nws tuaj yeem ua haujlwm rau kev sib txuas cov khoom siv lossis cov kav dej uas yuav tsum tau kho cov kev sib hloov los yog kev sib hloov.
Adjustable Flange Txuas:Hom kev sib txuas no tso cai rau kev kho kom zoo thiab hloov kho thaum sib dhos. Nws yog feem ntau siv rau hauv cov tshuab uas yuav tsum tau muaj qee theem ntawm kev hloov pauv thiab kev hloov pauv muaj peev xwm hloov mus rau qhov sib txawv ntawm kev ua haujlwm lossis ib puag ncig..
Raws li cov duab ntawm flange, nws tuaj yeem muab faib ua hom hauv qab no:
Square Flange
Cov flanges no yog square lossis rectangular nyob rau hauv cov duab thiab feem ntau muaj plaub lub qhov rau kho. Square flanges tuaj yeem siv rau kev sib txuas tshwj xeeb hauv cov kav dej, nrog rau kev sib txuas cov kav dej square lossis duab plaub.
Lub voj voog flange
Lub voj voog flanges yog hom ntau tshaj plaws, muaj lub ntsej muag sib npaug thiab feem ntau muaj lub ntsej muag sib npaug ntawm lub ntsej muag thiab lub qhov ntsia hlau rau kev sib txuas. Hom flange no yog siv dav hauv ntau yam kev sib txuas ntawm cov yeeb nkab.
Oval flange
Oval flanges muaj lub ntsej muag oval nrog lub ntsej muag oval flange thiab sib thooj qhov ntsia hlau. Oval flanges yuav siv tau rau qee qhov kev thov tshwj xeeb, tab sis kuj tsis tshua muaj.
