Zimagwira ntchito pogwiritsa ntchito kasupe kapena pisitoni mkati mwa valavu kuti madziwo azingoyenda mbali imodzi ndikulepheretsa kutuluka kobwerera. Madziwo akamapita kutsogolo, valavu imatseguka ndipo madziwo amatha kudutsa momasuka. Madziwo akamalowera chakumbuyo, valavu imatseka ndikulepheretsa madziwo kuti asadutse. Zomwe zimakwaniritsa cholinga chowongolera njira yamadzimadzi komanso kuthamanga. Popanga mafakitale, valavu yakumbuyo yam'mbuyo nthawi zambiri imagwiritsidwa ntchito poyang'anira kuthamanga ndi kupanikizika mu dongosolo la mapaipi kuti zitsimikizire kuti dongosololi likuyenda bwino.
Kodi ntchito ya kuthamanga kwa msana ndi chiyani?
Ntchito yake ndikusunga kupanikizika kwina kwa kumbuyo kapena kuteteza kumbuyo kwa kayendedwe ka mapaipi. M'kati mwa madzi kapena gasi, ngati kuthamanga kwa payipi kumakhala kotsika kuposa mtengo wina, kumatsogolera kumadzi kapena gasi, izi zimatchedwa kubwereranso. Valavu yakumbuyo yakumbuyo imatha kusinthidwa ndikusintha kutsegulira kwa valve. Kotero kuti kuthamanga mu payipi kukhalabe mkati mwa osiyanasiyana, motero kupewa kuchitika kwa mmbuyo otaya chodabwitsa.
