Chophimba cha rabaravalavu yoyezera madziKawirikawiri imakhala ndi thupi la valavu, chivundikiro cha valavu, chivundikiro cha rabara ndi zinthu zina. Pamene chivundikirocho chikuyenda patsogolo, kupanikizika komwe kumapangidwa ndi chivundikirocho kumakankhira chivundikiro cha rabara kuti chitseguke, kuti chivundikirocho chizitha kudutsa bwino mu valavu yosabwerera ndikuyenda kupita komwe chikupita. Chivundikirocho chikakhala ndi kayendedwe kobwerera m'mbuyo, kupsinjika kobwerera m'mbuyo kwa chivundikirocho kudzapangitsa chivundikirocho kutseka mwachangu komanso mwamphamvu pampando wa valavu, potero kuletsa chivundikirocho kuti chisagwere motsutsana ndi mphamvu yamagetsi ndikuwonetsetsa kuti chivundikirocho chikuyenda mbali imodzi yokha.

Valavu yowunikira ma flap a rabara imapereka zabwino zambiri poyerekeza ndi ma valavu owunikira nthawi zonse:

1.Good kusindikiza ntchito

Chophimba cha rabara chili ndi kusinthasintha kwabwino komanso kusinthasintha, ndipo chimatha kuyikidwa bwino ndi mpando kuti chiteteze kutayikira kwa media, ndipo kutseka kwake kumakhala bwino kuposa valavu yoyezera zitsulo.

2. Kukana madzi pang'ono

Chophimba cha rabara chimatha kutsatira bwino njira ya madzi akatsegulidwa, ndipo mawonekedwe ake ndi zinthu zake zimapangitsa kuti kukana kwa madzi kukhale kochepa, zomwe zingachepetse kutayika kwa mphamvu ndikuwonjezera magwiridwe antchito a dongosolo la mapaipi.

3. Zotsatira zabwino zotonthoza

Zipangizo za rabala zimakhala ndi mphamvu yoyamwa ndi kuchepetsa phokoso, ndipo zimatha kuchepetsa kugwedezeka kwa madzi ndi phokoso pamene valavu yoyang'anira yosabwerera yatsekedwa, ndikupanga malo ogwirira ntchito chete pamakina.

4. Kukana dzimbiri

Mphira uli ndi kukana dzimbiri bwino, umatha kusintha kuti ugwirizane ndi mitundu yosiyanasiyana ya zinthu, sizivuta kuziwononga ndi asidi ndi alkali ndi zinthu zina zowononga, ndipo umawonjezera moyo wa valavu yoyezera chitsulo choponyedwa.

Ma valve oyezera raba nthawi zambiri amagwiritsidwa ntchito m'makina operekera madzi ndi ngalande, malo oyeretsera zinyalala, malo opopera madzi, makina ozimitsa moto ndi minda ina. Mu makina oyeretsera madzi ndi ngalande, madzi amatha kubwereranso kuti atsimikizire kuti madzi ndi otetezeka komanso otetezeka. Mu fakitale yoyeretsera zinyalala, imatha kuonetsetsa kuti zinyalala zikuyenda m'njira yomwe yatchulidwa mu ndondomeko yoyeretsera, ndikupewa kusakanikirana kwa zinyalala m'magawo osiyanasiyana oyeretsera, zomwe zimakhudza zotsatira za kuyeretsa.

Mu siteshoni yopopera madzi, imatha kuletsa madzi kubwerera akamatseka, ndikuteteza pampu ndi zida zina kuti zisawonongeke. Mu makina ozimitsa moto, kuyang'anira bwino ntchito yake kungathandize kuonetsetsa kuti madzi ozimitsa moto akupezeka bwino ngati pakufunika kutero kuti ntchito yozimitsa moto ipite patsogolo bwino.
