Zingwe zazikulu zodzilamulira zowongolera

Valve yodziyimira yokha ndi mtundu wa valavu yomwe imagwiritsidwa ntchito mu mafakitale olamulira. Imagwiritsa ntchito mphamvu yake yodziyikirira kuti itsegule valavu

Popanda kufunikira kwa mphamvu zakunja.

Valayi ili ndi izi:

1. Valati yodzilamulira yokhayokha imatengera mfundo zamphamvu zamadzimadzi kuti muyendetse kutseguka ndi kutseka kwa valavu kudzera pakusintha kwa mavuto

madzi. Kapangidwe kameneka kamalola valavu kuti ingoyendetsa madzi osafunikira popanda mphamvu yakunja.

2. Valavuyo ili ndi mawonekedwe oyankha mwachangu ndipo amatha kuyankha kuti asinthe m'madzi otuluka nthawi yomweyo kuti akwaniritse kutentha. Khalidwe ili

amadzipangitsa kuti azikonzanso bwino kwambiri pazomwe zimafunikira kusintha pafupipafupi.

3. Valain yodzilamulira nokha ili ndi magwiridwe antchito abwino ndipo amatha kuwongolera mayendedwe ndikukakamizidwa ndi madzi. Mapangidwe ake amapangidwa

Madziwo kuti asunge malo osalala podutsa valavu, kuchepetsa nkhawa za madzi.

Mwachidule, valavu yothandizira yokha ndi valavu yogwira ntchito kwambiri yomwe imatha kuyendetsa mayendedwe ndikukakamizidwa ndi madzi ampungula komanso molondola. Amagwiritsidwa ntchito kwambiri

Njira zowongolera mafakitale ndipo zimatithandizira odalirika kuti azilamulira.

Zogulitsa zazikuluzikulu zimaphatikizapo valavu yowongolera ya chibayo, valavu ya mpira, valavu yamagetsi, valavu yopendekera, yopatsa chidwi.
