Ulusi wakunja wochepetsera valavu ya mpira wamkuwa ndi mtundu wa valve wamba womwe umagwiritsidwa ntchito kwambiri mu valavu.
Kuti ulusi wakunja uchepetse valavu ya mpira wamkuwa ukhale wokhazikika komanso wautali pautumiki, zinthu zotsatirazi ziyenera kutsatiridwa:
1. Musanagwiritse ntchito, gwiritsani ntchito madzi kuyeretsa payipi ndi gawo la valavu likusefukira kuti zitsulo zotsalira ndi zinyalala zisalowe m'bowo la valavu ya mpira.
2. Pamene ulusi wakunja wochepetsera valavu ya mpira wamkuwa watsekedwa, pamakhalabe sing'anga yotsalira m'thupi la valve, ndipo imakhala ndi mphamvu inayake.Musanayambe kukonzanso valavu ya mpira, tsegulani valavu yotseka kutsogolo kwa valavu ya mpira, tsegulani valavu ya mpira yomwe imayenera kukonzedwanso, ndikumasulani mphamvu ya mkati mwa thupi la valve.
3. Nthawi zambiri, PTFE imagwiritsidwa ntchito ngati chosindikizira cha ma valve otsekedwa ndi mpira, ndipo malo osindikizira a ma valve osindikizidwa olimba amapangidwa ndi zitsulo.Ngati valavu yapaipi yapaipi ikufunika kutsukidwa, ndikofunikira kusamala kuti musawononge mphete yosindikizira komanso kutayikira panthawi ya disassembly.
4. Pochotsa ndi kusonkhanitsa valavu ya mpira wa flanged, ma bolts ndi mtedza pa flange ayenera kukhazikitsidwa poyamba, ndiye kuti mtedza wonse uyenera kumangirizidwa pang'ono, ndipo potsirizira pake ukhale wokhazikika.Ngati mtedza wamtundu uliwonse umakhazikitsidwa mokakamiza poyamba, ndiyeno mtedza wina umakhazikika, malo a gasket adzawonongeka kapena kusweka chifukwa cha yunifolomu ya yunifolomu pakati pa malo a flange, zomwe zimapangitsa kuti pakhale kutayikira kwa sing'anga kuchokera ku valve flange.
