Ntchito yaikulu ya valavu ndikulekanitsa zida ndi makina opangira mapaipi, kuwongolera kutuluka, kuteteza kubwereranso, kuwongolera ndi kutulutsa kupanikizika, ndilo gawo lolamulira la dongosolo lamadzimadzi, udindo ndi wofunika kwambiri.Choncho, mu ntchito wamba ndondomeko ayenera kulabadira kukonza valavu ndi kukonza.

1. Ntchito Yokonza Tsiku ndi Tsiku ya Vavu

1.1 Malo osungiramo ma valve ayenera kuzindikiridwa, ayenera kusungidwa m'chipinda chowuma mpweya wabwino, ndikuletsa ndimeyi pamapeto onse awiri.

1.2 Valavu iyenera kuyang'aniridwa nthawi zonse, ndikuchotsa dothi pamwamba pake yokutidwa ndi mafuta odana ndi dzimbiri.

1.3 Vavu ikayikidwa ndikugwiritsidwa ntchito, iyenera kusinthidwa nthawi zonse kuti iwonetsetse kuti ikuyenda bwino.

1.4 Ayenera kuyang'ana ngati ma valve osindikizira pamwamba avala, komanso malinga ndi momwe akukonzera kapena kusintha.

1.5 Chongani tsinde ndi tsinde nati trapezoidal ulusi kuvala, kulongedza kwachikale komanso kusavomerezeka, ndipo sinthani zofunikira.

1.6 Yesani ntchito yosindikiza ya valve kuti muwonetsetse kuti ikugwira ntchito.

1.7 Valavu iyenera kukhala yogwira ntchito bwino, ma flange ndi mabakoketi athunthu, ulusi wosasunthika, osasunthika.

1.8 Ngati gudumu lamanja likusowa, liyenera kumalizidwa mu nthawi ndipo silingasinthidwe ndi sipika.

1.9 Kuyika chithokomiro sikuloledwa kupotoza kapena kusakhala ndi kusiyana kolimba.

1.10 Ngati valavu ikugwiritsidwa ntchito m'malo ovuta, osatetezeka kumvula, matalala, fumbi, mchenga ndi zonyansa zina, ziyenera kuyika chivundikiro chotetezera tsinde la valve.

1.11 Wolamulira pa valavu ayenera kusungidwa bwino, molondola, momveka bwino, chisindikizo cha valve, kapu.

1.12 Jekete yotsekereza sayenera kukhala kukhumudwa, ming'alu.

1.13 Mavavu akugwira ntchito, pewani kuwamenya kapena kuthandizira katundu wolemetsa.

2. Ntchito Yosamalira Kuyikira Mafuta a Valve

Katswiri wokonza valavu isanayambe komanso itatha kuwotcherera kumagwira ntchito yofunika kwambiri pa ntchito ya valve pakupanga ndi kugwira ntchito.Kusamalira moyenera komanso mwadongosolo kudzateteza ntchito ya valve moyenera ndikutalikitsa moyo wautumiki wa valve.Kukonza ma valve kungawoneke kosavuta, koma sichoncho.Nthawi zambiri pamakhala mbali zina za ntchito zomwe zimanyalanyazidwa.

2.1 Jakisoni wa Mafuta a Vavu, Samalani Kuchuluka Kwa Mafuta.

Mfuti ya Grease ikapakidwa mafuta, wogwiritsa ntchito amasankha valavu ndi njira yolumikizira jekeseni kuti agwire ntchito yojambulira mafuta.Pali zinthu ziwiri: mbali imodzi, jekeseni wochepa wamafuta osakwanira, kusindikiza pamwamba chifukwa chosowa mafuta komanso kuvala mwachangu.Kumbali inayi, jekeseni wambiri wamafuta, zomwe zimapangitsa kuti ziwonongeke.Palibe kuwerengera kolondola kwa mphamvu yosindikiza ya ma valve osiyanasiyana malinga ndi mtundu wa valve.Mphamvu yosindikiza imatha kuwerengedwa molingana ndi kukula kwa valve ndi gulu, ndipo mafuta oyenerera akhoza kubayidwa moyenerera.

2.2 Jakisoni wa Mafuta a Valve, Tiyenera Kusamala Vuto la Kupanikizika.

Pa ntchito jakisoni, kuthamanga jekeseni amasintha mwachizolowezi.Kupanikizika ndikotsika kwambiri, kutayikira kwa chisindikizo kapena kulephera kwamphamvu ndikokwera kwambiri, kamwa ya jakisoni wamafuta ndi yotsekeka, mafuta osindikizira amkati amaumitsa kapena mphete yosindikizira ndi mpira wa valve, mbale ya valve imakumbatira yafa.Kawirikawiri kuthamanga kwa jekeseni wa mafuta kumakhala kochepa kwambiri, jekeseni wa mafuta pansi pa valve ya valve, kawirikawiri imapezeka mu valve yaing'ono yachipata.Kuthamanga kwa jekeseni ndikokwera kwambiri, kumbali imodzi, fufuzani jekeseni wa jekeseni, monga kutsekeka kwa bowo la mafuta kuti musinthe;Komano, kugwiritsa ntchito kuyeretsa madzimadzi mobwerezabwereza kufewetsa kulephera kwa kusindikiza mafuta, ndi jekeseni wa mafuta atsopano m'malo.Kuphatikiza apo, mtundu wosindikiza ndi zinthu zosindikizira, komanso kupanikizika kwa jekeseni, mitundu yosiyanasiyana ya kusindikiza imakhala ndi kuthamanga kosiyana kwa jekeseni, vuto lalikulu la jekeseni wolimba kwambiri kuposa chisindikizo chofewa.
