Ma valve angapo omwe amagwiritsidwa ntchito m'mapaipi a mafakitale, ma valve a mpira ali ndi njira zambiri zogwiritsira ntchito, kaya ndi madzi, mafuta, gasi kapena mapaipi wamba wamba kapena mikhalidwe yovuta yogwirira ntchito yomwe imakhala ndi tinthu tating'onoting'ono tating'onoting'ono, kaya ndi kutentha kochepa, kutentha kwambiri, kapena zowononga. chilengedwe, inu Mukhoza kuona mthunzi wa valavu mpira.Monga valavu yogwiritsidwa ntchito kwambiri, ndikofunikira kumvetsetsa njira yoyenera yoyikamo kuti mugwiritse ntchito mankhwalawa moyenera komanso mwasayansi (1) Kukonzekera musanayike.
①Valve ya mpiraunsembe njira Mapaipi kutsogolo ndi kumbuyo kwa valavu mpira ali okonzeka.Mipope yakutsogolo ndi yakumbuyo iyenera kukhala coaxial, ndipo malo osindikizira a ma flanges awiriwo azikhala ofanana.Chitolirocho chiyenera kupirira kulemera kwa valve ya mpira, apo ayi payipi iyenera kukhala ndi chithandizo choyenera.
②Tsukani mapaipi musanayambe ndi pambuyo valavu kuchotsa mafuta, kuwotcherera slag ndi zonyansa zina zonse mu payipi.
③Yang'anani chizindikiro cha valavu ya mpira kuti muwone kuti mpirawo ulibe.Tsegulani ndi kutseka maziko a valve kangapo kuti mutsimikizire kuti akugwira ntchito bwino.
④Chotsani gawo loteteza pa flange yolumikizira ya valavu yakumanzere ya mpira.
⑤Yang'anani dzenje la valve, chotsani dothi lomwe lingatheke, ndiyeno yeretsani dzenjelo.Ngakhale zinthu zazing'ono zakunja pakati pa mpando wa valve ndi mpira zimatha kuwononga malo osindikizira a valve.

① Ikani mafuta opaka paipi.Mapeto onse a valve ndi -J amaikidwa kumapeto kwa h.Valve ya lever drive imatha kukhazikitsidwa pamalo aliwonse papaipi.Komabe, valavu yamanja ya mpira yokhala ndi bokosi la gear ndi valavu ya mpira wa pneumatic yokhala ndi dalaivala wa pneumatic imayikidwa molunjika, ndiye kuti, imayikidwa paipi yopingasa, ndipo chipangizo choyendetsa chili pamwamba pa payipi.
②Mapangidwe a valve flange ndi flange yamapaipi amafuna kuyika gasket.
③Maboliti pa flange ayenera kukhala ofanana ndi omangika imodzi ndi imodzi komanso molingana.④Lumikizani payipi ya pneumatic 'pamene woyendetsa pneumatic agwiritsidwa ntchito).
(3) Kuyang'ana pambuyo kukhazikitsa
① Gwiritsani ntchito dalaivala kuti atsegule ndi kutseka valavu ya mpira kangapo.Iyenera kukhala yosinthika komanso yopanda kuyimirira kuti itsimikizire kuti ikugwira ntchito bwino.②Kapangidwe ka payipi yolumikizira kumafuna kuwunika kosindikiza kwapaipi yapaipi ndi mpira.
