Ma flanges a carbon steelamagwiritsidwa ntchito kwambiri pazakudya zatsiku ndi tsiku, ndikugwiritsa ntchito kwambiri komanso kudya mwachangu.Choncho, nthawi zonse kukonza mpweya zitsulo flanges ayenera kukhala ndi malamulo ena kusunga khalidwe la mpweya zitsulo flanges mmene ndingathere ndi bwino ntchito bwino.Ndiroleni ndikugawireni miyeso yofunikira yokonzekera kuti mugwire bwino ntchitochitsulo chosapanga dzimbirindi carbon steel flanges.
1. Musanagwiritse ntchito, yeretsani chitoliro ndi gawo losefukira la valavu ndi madzi oyera kuti muteteze zotsalira zachitsulo ndi zinyalala zina kulowa mkati mwa thupi la valve.
2. Pamene flange ya carbon steel yatsekedwa, sing'anga ina imakhalabe mu thupi la valve ndipo imakhala ndi mphamvu zina.Musanayambe kukonzanso mpweya wa carbon steel flange, tsekani valavu yotseka kutsogolo kwa carbon steel flange, tsegulani carbon steel flange kuti muwonjezedwe, ndikumasulani mphamvu ya mkati mwa thupi la valve.Ngati muli ndi flange yamagetsi ya carbon steel kapena valavu ya mpira wa pneumatic, mphamvu ndi mpweya ziyenera kuchotsedwa poyamba.
3. Nthawi zambiri,PTFEamagwiritsidwa ntchito ngati chosindikizira chosindikizira chofewa cha carbon steel flange, ndipo malo osindikizira a valve olimba osindikizira amapangidwa ndi zitsulo zowonekera.Ngati kuli kofunikira kuyeretsa valavu ya mpira wa chitoliro, chisamaliro chiyenera kutengedwa kuti chiteteze kutayikira chifukwa cha kuwonongeka kwa mphete yosindikizira panthawi ya disassembly.
4. Pochotsa mpweya wa carbon steel flange, ma bolts ndi mtedza pa flange ayenera kukhazikitsidwa poyamba, ndiyeno mtedza wonse uyenera kumangirizidwa pang'ono ndikukhazikika.Ngati mtedza wina waumitsidwa moumiriza mtedza wina usanakhazikitsidwe, gawo la gasket lidzawonongeka kapena kusweka chifukwa chakusanjana pakati pa nkhope za flange, zomwe zimapangitsa kuti pakhale kutayikira kwapang'onopang'ono kuchokera kumagulu a valve flange.
5. Ngati valavu yatsukidwa, chosungunulira chomwe chimagwiritsidwa ntchito sichiyenera kutsutsana ndi zigawo zomwe ziyenera kutsukidwa osati kuwononga.Ngati ndi flange yapadera ya carbon steel ya gasi, imatha kutsukidwa ndi mafuta.Zigawo zina zimatha kutsukidwa ndi madzi obwezeretsedwa.Pakuyeretsa, fumbi lotsalira, mafuta ndi zomangira zina ziyenera kutsukidwa bwino.Ngati sangathe kutsukidwa ndi madzi oyera, akhoza kutsukidwa ndi mowa ndi zinthu zina zoyeretsera popanda kuwononga valavu ndi ziwalo.Mukamaliza kuyeretsa, dikirani kuti choyeretsera chiwonongeke kwathunthu musanasonkhanitse.
6. Ngati kutayikira pang'ono kumapezeka pakulongedza panthawi yomwe mukugwiritsa ntchito, mtedza wa ndodo ya valve ukhoza kumangika pang'ono mpaka kutayikirako kutha.Musapitirize kumangitsa.
Kuonjezera apo, ngati mpweya wa carbon steel flange umayikidwa panja kwa nthawi yaitali, ngati palibe miyeso yopanda madzi komanso yotetezera chinyezi, imayambitsa dzimbiri matupi a valve ndi zigawo zina.Pofuna kuonetsetsa kukhazikika kwa carbon steel flange, mayesero ayenera kuchitidwa musanagwiritse ntchito.
