Pav ca vuam flanges feem ntau yog siv rau cov roj li qub thiab cov kav dej ntuj. Vim tias lub caj dab luv luv tuaj yeem txhim kho qhov nruj thiab kev thauj khoom muaj peev xwm ntawm flange. Flat vuam flanges yog siv rau kev tshaj tawm. Flat welding flanges nrog lub caj dab yog tsim rau cov nplaim taws, tawg, tawg, thiab muaj kuab lom. Lub sealing nto ntawm tiaj vuam flanges tuaj yeem yog convex, concave convex, thiab mortise thiab tenon nto. Lawv txawv ntawm cov qauv, sealing nyhuv, thiab lub zog.
Flat welding flanges feem ntau hu ua pav ca, tseem hu ua lap welding flanges. Kev sib txuas ntawm lub tiaj tiaj vuam flange thiab cov raj xa dej yog ntxig cov raj xa mus rau hauv lub qhov flange mus rau qhov chaw tsim nyog ua ntej lap welding. Cov yam ntxwv ntawm lub tiaj vuam flanges: tiaj vuam flanges tsis tsuas yog txuag chaw thiab txo qhov hnyav, tab sis kuj xyuas kom tsis txhob muaj kev sib tsoo ntawm qhov sib koom ua ke thiab kev sib khi zoo. Yog vim li cas qhov kev txo qis ntawm qhov loj ntawm compact flanges yog qhov txo qis hauv txoj kab uas hla ntawm lub foob, uas yuav txo qhov kev sib tshuam ntawm qhov sib khi nto. Qhov zoo ntawm cov vuam flanges yog raws li nram no:
1. Yuav kom compact lub sealing nto ntawm lub tiaj vuam flange, tsuas yog ib tug me me npaum li cas ntawm siab yuav tsum tau. Raws li qhov xav tau siab txo qis, qhov loj thiab ntau ntawm bolts kuj txo raws li.
2. Kev tsim cov vuam vuam flanges tuaj yeem txuag cov ntaub ntawv thiab txo cov nqi. Thaum cov khoom siv raw ntawm cov raj xa dej tshwj xeeb thiab tus nqi siab, cov nqi vuam ntawm flanges ua los ntawm tib cov ntaub ntawv raw yuav siab heev. Siv hom flange no tuaj yeem txuag tau cov nqi khoom zoo. Hom vuam flange no yog qhov tsim nyog rau kev tsim kho, vim nws tsis yooj yim los ua kom lub qhov flange ntsia liaj qhov rooj thaum sib txuas lossis kom tsis txhob hloov cov khoom flange bolt qhov.
3. Flat vuam flanges tuaj yeem txuag tau qhov chaw thiab txo qhov hnyav thaum siv. Nws yog ib qho tseem ceeb kom ntseeg tau tias lub taub hau tsis xau cua. Nws muaj kev sealing zoo heev. Yog vim li cas rau qhov txo qhov loj ntawm compact flanges yog vim qhov txo qis hauv txoj kab uas hla ntawm lub foob, uas txo qhov cross-section ntawm sealing nto. Tsis tas li ntawd, flange gaskets tau tam sim no tau hloov los ntawm kev sib khi lub nplhaib kom ntseeg tau tias kev sib txuam zoo ntawm cov welded flange ntsaws ruaj ruaj uas tig mus rau qhov chaw sib khi.
Tab sis nws kuj muaj qee qhov tsis zoo, qhov tsis zoo ntawm cov vuam flanges:
Lub ntsiab tsis zoo ntawm lub tiaj vuam flanges yog tias lawv tsis tuaj yeem lav tsis muaj qhov xau. Qhov no yog qhov tsis muaj kev npaj: kev sib txuas yog dynamic, thiab cyclic loads xws li thermal expansion thiab fluctuations tuaj yeem ua rau kev txav ntawm flange ntsej muag, yog li cuam tshuam rau kev ua haujlwm ntawm flange, ua rau nws txoj kev ncaj ncees, thiab ua rau cov dej xau.
