Mankhwala ntchito payipi utsi nthunzi ya matenthedwe wagawo mphamvu kukatentha kuti utsi nthunzi owonjezera.
- Thupi la valve lokhazikika limakhala ndi mphamvu yayikulu komanso zinthu zodalirika. Kulumikizana kwa welded kumalandiridwa pakati pa thupi la valavu ndi payipi.
- Ming'alu yapakati ya thupi la valavu ndi boneti ya valavu imadzipangira zokhazokha, zokhala ndi zopasula komanso kusonkhanitsa kosindikiza kosadalirika. Kutalika kwapanikizika ndikomwe ntchito yosindikiza ndiyabwino.
- Ndi kuwongolera kovutikira kapena chivundikiro, pakati pa thupi la valavu kumatha kuteteza kuphulika kwa tsinde la valavu komwe kumayambitsidwa ndi kugwedera.
- Ndikutsekemera kwa cobalt kolimba kolimba, kusindikiza pamwamba kumatsimikizira kusiyana kwake kwakukulu ndi kuuma; kutalika-kuwotcherera kutalika kwa chimbale vavu ndi mpando ≥5mm; umapezeka ndendende, kuthamangira pamanja ndi kumva kuwawa ndi kukana dzimbiri, kuwonetsetsa kuti malo osindikizira ali pamwamba pa 90%, pozindikira kutayikira kwa zero ndikuwonjezera moyo wautumiki moyenera.
- Ndikutuluka kwake kolimba, tsinde la valavu limatha kulimbana ndi dzimbiri.
- Kapangidwe kakang'ono, kutsegula bwino ndi kutseka magwiridwe antchito, kutalika kotsika komanso kukonza kosavuta.
- Zona mapayipi utsi nthunzi, zimaonetsa kutentha ndi kuthamanga kukana.
- Okonzeka ndi chipangizo chamagetsi, imatha kuzindikira kuwongolera kwakutali ndi magwiridwe antchito am'deralo.
