Ntawm qhov chaw tsim kho, flanges tuaj yeem pom txhua qhov chaw. Txawm li cas los xij, daim ntawv thov ntawm flanges sib txawv kuj txawv.
Hnub no kuv yuav qhia rau koj paub tias lub tiaj tiaj vuam flange yog dab tsi thiab nws siv rau dab tsi.
Vim txoj kev vuam sib txawv, cov npe ntawm cov flanges yuav luag sib txawv. Niaj hnub no peb tab tom tham txog kev siv cov fillet weld kev twb kev txuas, uas yog ib tug flange khoom hu ua ib tug tiaj weld flange. Hauv kev lag luam, nws yog lub npe hu ua "tus huab tais ntawm cov khoom txuag", vim tias nws muaj cov qauv yooj yim thiab txuag cov ntaub ntawv piv nrog lub caj dab taub qab vuam flange. Qhov tsis zoo yog tias lub sealing tsis zoo heev, thiab nws yog qhov zoo dua rau welding flange nrog lub caj dab.
Lub sealing nto ntawm lub tiaj welded flange yog muab faib ua concave thiab convex nto. Feem ntau peb muab cov gasket tso rau hauv qhov chaw concave. Cov tshuab ntxhua khaub ncaws uas siv tau yog: txhua yam ntawm cov khoom siv tsis yog xim hlau, cov khoom siv sib txuas, cov khoom siv hlau thiab cov hlua khi. Ntau yam qauv ntawm cov nplhaib sab hauv, hlau yoj pads, hlau tiaj tus ncoo, thiab hlau hniav pads.
Yuav saib dab tsi? Lub siab sealing yuav tsum tsis tuaj yeem khaws cia ntawm lub ntsej muag welded flange, yog li nws txaus los xyuas thiab hloov cov khoom siv gasket ib ntus lossis siv lub flange fluted nrog rau concave thiab convex flange nrog ob nres (xws li high- siab seals, hlau ca gaskets).
Tau kawg, nws tseem tau hais txog ntawm no tias cov khoom xav tau, thiab cov yam ntxwv ntawm ntau yam flanges kuj tau tham txog: lub tiaj tus welded sib koom ua ke muaj lub ntsej muag convex, grooves yog ua rau ntawm qhov chaw convex, thiab tom qab ntawd cov yeeb nkab yog welded sab hauv. Lub qhov (socket) yog welded yam tsis muaj convex nto, ua ib tug zawj ncaj qha nyob rau hauv lub flange lub cev, zoo li lub qhov nyob rau hauv lub flange, thiab ces qhib ib tug zawj.
Tau kawg, nws kuj tau hais luv luv ntawm no tias cov vuam vuam ntawm lub flange feem ntau yog siv rau lub tiaj vuam flange, lub taub qab vuam feem ntau yog siv rau lub taub qab vuam flange, qhov sib txawv ntawm lub vuam flange thiab lub taub qab vuam flange. sealing nto ntawm lub tiaj vuam flange tuaj yeem ua rau peb hom: du, concave-convex thiab tus nplaig-groove, thiab lub pob tw vuam flange txais lub concave-convex sealing nto; Lub kaum sab xis vuam yog 90 degree thaum vuam nrog lub nozzle, uas yog hu ua tiaj vuam.
