Ma valve opindika ndi ofala kwambiri ndipo amagwira ntchito bwino kwambiri m'mapaipi amafakitale. Kuyambira pa mizere yopangira mafakitale mpaka maukonde apansi panthaka m'mizinda,
Amateteza mwakachetechete njira zoyendera madzi osiyanasiyana monga madzi, mafuta, ndi gasi, kuonetsetsa kuti chilichonse chikuyenda bwino.
Mtundu uwu wa valavu ndi wosavuta kusamalira. Umakhazikika bwino paipi kudzera m'ma flange plates kumapeto onse a thupi la valavu, pogwiritsa ntchito mabolts.
Njira yolumikizira iyi ndi yolimba ndipo imatha kupirira kuthamanga kwambiri komanso kutentha kwambiri. Kuphatikiza ndi kutseka kwa gasket, sikungathe kutuluka madzi ndipo ili ndi chitetezo chambiri.
Ubwino winaNdikosavuta kukonza. Ngati pakufunika kusintha kapena kukonza, ingochotsani mabotolo ndipo valavu yonse ikhoza kuchotsedwa. Palibe chifukwa chosuntha payipi, zomwe zimapulumutsa nthawi ndi khama komanso zimachepetsa nthawi yogwira ntchito.
Chifukwa cha makhalidwe amenewa, ma valve a flange amapezeka m'magwiritsidwe ntchito ambiri ofunikira. Mwachitsanzo, m'mafakitale monga petrochemicals ndi malo opangira magetsi, amagwiritsidwa ntchito kwambiri polamulira mafuta, gasi kapena nthunzi;
Mu makina operekera madzi, otenthetsera ndi oziziritsa mpweya mumzinda, amachitanso gawo lofunikira pakulamulira kayendedwe ka madzi ndi kusintha mapaipi. Kuphatikiza apo, m'maofesi akuluakulu, zombo, ndi mapulojekiti oyeretsera madzi, kaya ndi madzi ozizira, mapaipi oteteza moto, kapena mayendedwe amadzi osaphika, ma valve a flange akuchita gawo lofunika kwambiri.
Tinganene kuti ngakhale kuti valavu ya Flan singakhale yokopa maso, kwenikweni imagwira ntchito yofunika kwambiri pakugwira ntchito kwa mafakitale amakono.Ndi kapangidwe kake kosavuta komanso kodalirika, imapangitsa kuti mapaipi azikhala otetezeka komanso imapangitsa kukonza tsiku ndi tsiku kukhala kosavuta.
