Valve ya mpira wotsekedwa ndi jekete

Zogulitsa katundu 1.Kukana kokwanira ndi kofanana ndi kutalika kwa chitoliro; 2. Kapangidwe kosavuta, voliyumu yaying'ono ndi kulemera kopepuka; 3.Pakali pano, kusindikiza pamwamba pa valve ya mpira kumagwiritsidwa ntchito kwambiri pulasitiki yokhala ndi ntchito yabwino yosindikiza, ndipo imagwiritsidwa ntchito kwambiri mu vacuum system; 4.N'zosavuta kugwiritsa ntchito, kutsegula ndi kutseka mwamsanga, kuchokera kutseguka kwathunthu mpaka kutseka kwathunthu kwa 90 ° kuzungulira, koyenera kulamulira kutali; 5. Kukonza kosavuta, mawonekedwe osavuta a valve ya mpira, mphete yosindikizira yosunthika, kusokoneza kosavuta ndi kusintha; 6. Pamene valavu yatsegulidwa kwathunthu kapena kutsekedwa, kusindikiza pamwamba pa mpira ndi mpando wa valavu zimasiyanitsidwa ndi sing'anga, ndipo kukokoloka kwa malo osindikizira a valve sikudzayamba pamene sing'anga ikudutsa; 7.Ili ndi ntchito zosiyanasiyana, kuyambira m'mimba mwake mpaka mamilimita angapo, mpaka mamita angapo, kuchokera ku vacuum yapamwamba mpaka kupanikizika kwambiri. Mpirawo ukazungulira madigiri 90, cholowera ndi cholowera mpiracho chiyenera kukhala chozungulira, kuti muchepetse kutuluka.
