Ubwino wa valavu ya mpira yokhazikika ya dziko lonse

1. Kukana kwa madzimadzi ndi kochepa, ndipo valavu ya mpira yokhala ndi dzenje lonse ilibe kukana kwa madzi.

2. Kapangidwe kosavuta, kakang'ono kukula ndi kulemera kopepuka.

3. Yotseka komanso yodalirika. Pali malo awiri otsekera. Mphamvu yamagetsivalavu ya mpiraZipangizo zotsekera pamwamba zimagwiritsidwa ntchito kwambiri mu mapulasitiki osiyanasiyana, ndipo zimakhala ndi magwiridwe antchito abwino kwambiri otsekera, zomwe zimatha kutseka kwathunthu. Zimagwiritsidwanso ntchito kwambiri mu makina opumira mpweya.

4. Kugwiritsa ntchito kosavuta, kutsegula ndi kutseka mwachangu, kumangofunika kuzungulira 90° kuchokera potseguka kwathunthu mpaka potseka kwathunthu, zomwe ndizosavuta kugwiritsa ntchito patali.

5. Kukonza kosavuta, kapangidwe kosavuta ka valavu ya mpira, ndi mphete yotsekera yosunthika, yomwe ndi yosavuta kuichotsa ndikuyiyika m'malo mwake.

6. Mukatsegula kapena kutseka kwathunthu, pamwamba pa mpira ndi mpando wa valavu zimachotsedwa pa sing'anga. Ngakhale sing'anga ikadutsa, pamwamba pa sing'anga sizingawonongeke.

7. Kukula kwake kumayambira pa mamilimita angapo mpaka mamita angapo, ndipo kumagwiritsidwa ntchito m'njira zosiyanasiyana, ndipo kungagwiritsidwe ntchito pansi pa vacuum yambiri mpaka pa kuthamanga kwambiri.

8. Popeza valavu ya mpira imakhala ndi mawonekedwe opukuta potsegula ndi kutseka, ingagwiritsidwe ntchito pa media yokhala ndi tinthu tolimba tomwe timapachikidwa.
