Valavu ya pulagi yopaka mafuta yokhala ndi mphamvu yamagetsi ndi mtundu wa valavu yamafakitale opangidwa kuti aziwongolera kutuluka kwamadzi mkati mwa payipi.M'nkhaniyi, "mafuta" nthawi zambiri amatanthauza kugwiritsa ntchito mafuta odzola kapena osindikizira kuti achepetse mikangano ndikuwonetsetsa kuti ma valve akuyenda bwino.Kukhalapo kwa mawonekedwe a kupanikizika kwa valve mu kapangidwe ka valve kumapangidwira kuti pakhale mgwirizano kapena kupanikizika kofanana m'madera osiyanasiyana a valve, zomwe zingathandize kupititsa patsogolo ntchito yonse ndi kudalirika kwa valve, makamaka pa ntchito zothamanga kwambiri. Kupaka mafuta ndi kupanikizika mu valavu ya pulagi cholinga chake ndi kupititsa patsogolo kulimba kwake, mphamvu zake, komanso kupirira zovuta zogwirira ntchito.Zinthu izi zitha kupangitsa kuti mavavu achepetse komanso kung'ambika, kukhathamiritsa kusindikiza kukhulupirika, komanso kugwira ntchito bwino, zomwe zimapangitsa kuti mavavu azikhala ndi moyo wautali m'mafakitale. kuthamanga bwino, omasuka kufunsa zambiri mwatsatanetsatane.
1. Pressure balance type inverted oil seal plug vavu kapangidwe kazinthu ndizoyenera, kusindikiza kodalirika, magwiridwe antchito abwino, mawonekedwe okongola;
2. Mafuta osindikizira pulagi valavu inverted kuthamanga bwino dongosolo, kuwala lophimba kanthu;
3. Pali poyambira mafuta pakati pa thupi la valavu ndi malo osindikizira, omwe amatha kupaka mafuta osindikizira pampando wa valve nthawi iliyonse kudzera mumphuno yamafuta kuti awonjezere ntchito yosindikiza;
4. Zigawo zakuthupi ndi kukula kwa flange zitha kusankhidwa moyenerera malinga ndi momwe amagwirira ntchito kapena zofunikira za ogwiritsa ntchito kuti akwaniritse zosowa zosiyanasiyana zamainjiniya.

Ntchito yogulitsa pambuyo pa valve yoyandama yoyandama ndiyofunikira kwambiri, chifukwa nthawi yake yokha komanso yogwira ntchito pambuyo pogulitsa imatha kutsimikizira kuti ikugwira ntchito nthawi yayitali komanso yokhazikika.Zotsatirazi ndi zomwe zili mkati mwa ntchito zogulitsa pambuyo pa mavavu ena oyandama a mpira:
1.Kuyika ndi kutumiza: Ogwira ntchito pambuyo pa malonda adzapita kumaloko kukayika ndi kukonza valve yoyandama ya mpira kuti atsimikizire kuti ikugwira ntchito yokhazikika komanso yokhazikika.
2.Maintenance: Nthawi zonse sungani valavu ya mpira yoyandama kuti muwonetsetse kuti ili bwino kwambiri ndikuchepetsa kulephera.
3.Kuthetsa mavuto: Ngati valavu yoyandama ya mpira ikulephera, ogwira ntchito pambuyo pa malonda adzachitapo kanthu pa nthawi yaifupi kwambiri kuti atsimikizire kugwira ntchito kwake.
4.Kusintha kwazinthu ndi kukonzanso: Poyankha zipangizo zatsopano ndi matekinoloje atsopano omwe akubwera pamsika, ogwira ntchito pambuyo pa malonda adzalimbikitsa mwamsanga kukonzanso ndi kukonzanso njira zothetsera makasitomala kuti awapatse mankhwala abwino a valve.
5. Maphunziro a chidziwitso: Ogwira ntchito pambuyo pa malonda adzapereka maphunziro a chidziwitso cha valve kwa ogwiritsa ntchito kuti apititse patsogolo kasamalidwe ndi kasamalidwe ka ogwiritsa ntchito pogwiritsa ntchito ma valve oyandama.Mwachidule, ntchito yogulitsa pambuyo pa valve yoyandama iyenera kutsimikiziridwa mbali zonse.Ndi njira iyi yokha yomwe ingabweretsere ogwiritsa ntchito bwino ndikugula chitetezo.
