Mavavu, monga zinthu zina zamakina, amafunikiranso kukonza.Ngati ntchitoyi yachitika bwino, imatha kuwonjezera moyo wautumiki wa valve.Zotsatirazi zidzayambitsa kukonza kwa valve.
1. Kusungirako ndi kukonza ma valve
Cholinga cha kusunga ndi kukonza sikuwononga valavu mu yosungirako kapena kuchepetsa khalidwe.Ndipotu, kusungirako kosayenera ndi chimodzi mwa zifukwa zofunika zowonongeka kwa valve.
Vavu yosungirako ayenera kukhala mwadongosolo, mavavu ang'onoang'ono pa alumali, mavavu lalikulu akhoza mwaukhondo anakonza pa nyumba yosungiramo katundu pansi, osati molongosoka mulu, musalole flange kugwirizana pamwamba kukhudzana pansi.Izi siziri pazifukwa zokongola zokha, koma makamaka kuteteza valavu kuti isawonongeke.
Chifukwa cha kusungirako kosayenera ndi kugwiritsira ntchito, gudumu lamanja lathyoledwa, tsinde la valve lokhotakhota, gudumu lamanja ndi tsinde la valve losasunthika lotayirira, ndi zina zotero, zotayika zosafunikirazi ziyenera kupewedwa.
Kwa ma valve omwe sagwiritsidwa ntchito kwakanthawi kochepa, zodzaza asbestosi ziyenera kuchotsedwa kuti zisawonongeke ndi electrochemical corrosion komanso kuwonongeka kwa tsinde la valve.
Ma valve omwe angolowa kumene m'nyumba yosungiramo katundu ayenera kuyang'aniridwa.Mwachitsanzo, madzi amvula kapena dothi lomwe likulowa paulendo liyenera kupukuta ndi kusungidwa.
Polowera ndi potulukira valavu atsekedwe ndi pepala la sera kapena pepala lapulasitiki kuti dothi lisalowe.
Malo opangira ma valve omwe amatha kuchita dzimbiri mumlengalenga ayenera kuphimbidwa ndi mafuta oletsa chitetezo kuti ateteze.
Mavavu oikidwa panja, ayenera kuphimbidwa ndi zinthu zosagwirizana ndi mvula komanso zosagwira fumbi monga linoleum kapena tarpaulin.Malo osungiramo ma valve osungiramo zinthu ayenera kukhala aukhondo komanso owuma.

2. Kugwira ntchito ndi kukonza ma valve
Cholinga cha ntchito ndi kukonza ndikutalikitsa moyo wa valve ndikuwonetsetsa kutseguka ndi kutseka kodalirika.
Vavu tsinde ulusi, nthawi zambiri ndi valavu tsinde nati kukangana, yokutidwa ndi pang'ono chikasu youma mafuta, molybdenum disulfide kapena graphite ufa, mafuta.
Kwa valavu yomwe simatsegulidwa nthawi zambiri komanso kutsekedwa, m'pofunikanso kutembenuza gudumu lamanja nthawi zonse ndikuwonjezera mafuta ku ulusi wa tsinde kuti mupewe kuluma.
Kwa mavavu akunja, manja otetezera ayenera kuwonjezeredwa ku tsinde la valve kuti ateteze mvula, chipale chofewa ndi dzimbiri.
Ngati valavu ndi makina standby, m'pofunika kuwonjezera mafuta mafuta ku gearbox pa nthawi.
Vavu ikhale yaukhondo pafupipafupi.
Nthawi zonse fufuzani ndi kusunga umphumphu wa mbali zina za valve.Ngati mtedza wokhazikika wa gudumu la m'manja umagwa, uyenera kufananizidwa, apo ayi udzagaya mbali zinayi za kumtunda kwa tsinde la valve, pang'onopang'ono kutaya kudalirika kwa kufanana, ndipo ngakhale kulephera kuyamba.
Musadalire valavu kuti muthandizire zinthu zina zolemetsa, musayime pa valve.
Tsinde la valavu, makamaka gawo la ulusi, liyenera kupukuta pafupipafupi, ndipo mafuta omwe adadetsedwa ndi fumbi ayenera kusinthidwa ndi atsopano, chifukwa fumbi liri ndi zinyalala zolimba, zomwe zimakhala zosavuta kuvala ulusi ndi pamwamba. tsinde la valve, lomwe limakhudza moyo wautumiki.

3. Kusamalira kunyamula ma valve
Kuyika ndi chisindikizo chofunikira chomwe chimagwirizana mwachindunji ndi ngati kutayikira kumachitika pamene valavu imatsegulidwa ndi kutsekedwa, ngati kulephera kwa kulongedza, kumayambitsa kutayikira, valavu ndi yofanana ndi kulephera, makamaka valavu ya pipeline ya urea, chifukwa kutentha kwake kumakhala kokwera kwambiri, dzimbiri ndi mkulu, kulongedza ndi zosavuta kukalamba.Kulimbitsa kukonza kungatalikitse moyo wa kulongedza katundu.
Valavu ikachoka pafakitale, kuti zitsimikizire kuti kunyamulira kwapang'onopang'ono, nthawi zambiri zimayesedwa ndi static pressure test popanda kutayikira.Vavu ikatulutsidwa mu payipi, chifukwa cha kutentha ndi zinthu zina, pakhoza kukhala madzi, ndiye kuti m'pofunika kumangirira mtedza kumbali zonse ziwiri za chithokomiro panthawi, malinga ngati sichikutuluka, ndiyeno. seepage kachiwiri, musamangitse kamodzi, kuti mupewe kutaya kwa elasticity ya kulongedza ndi kutayika kwa ntchito yosindikiza.
Ena valavu kulongedza okonzeka ndi molybdenum disulfide kondomu phala phala, pamene ntchito kwa miyezi ingapo, ayenera kukhala nthawi yake kuwonjezera lolingana kondomu mafuta, pamene anapeza kuti filler ayenera kuwonjezeredwa, ayenera nthawi yake kuonjezera lolingana kulongedza katundu, pofuna kuonetsetsa ntchito yake yosindikiza.

4. Kusamalira mbali zotumizira ma valve
Vavu mukusintha, mafuta oyambira opaka mafuta akupitilizabe kutayika, kuphatikiza ndi kutentha, dzimbiri ndi zinthu zina, zipangitsanso mafuta opaka mafuta kukhala owuma nthawi zonse.Choncho, mbali zopatsirana za valve ziyenera kufufuzidwa nthawi zonse, zomwe zimapeza kuti kusowa kwa mafuta kuyenera kudzazidwa nthawi, pofuna kupewa kusowa kwa mafuta ndi kuonjezera kuvala, zomwe zimapangitsa kuti pakhale kufalikira kosasinthika ndi zolephera zina.

Kusamalira ma valve kuyenera kuchitidwa ndi maganizo asayansi, kuti apange ntchito yokonza ma valve kuti akwaniritse zotsatira zomwe akufuna komanso ntchito.Kuti apange ntchito yabwinobwino yopangira, kuchepetsa kuyimitsidwa ndikuwonjezera phindu lazachuma, mu valve, tiyenera kuchita izi mfundo zitatu:
Kusankha kolondola kwa mavavu ndiko maziko.
Kugwiritsa ntchito bwino valve ndiye chinsinsi.
Kukonza koyenera ndi chitsimikizo.
