Ubwino ndi kuipa kwa mavavu a pulagi

Pali mitundu yambiri ya ma valve, ndipo iliyonse ili ndi ubwino wake ndi zovuta zake. Nazi zabwino zisanu zazikulu za mavavu ndi zovuta zake, kuphatikizapo ma valve a zipata, ma valve a butterfly, ma valve a mpira, ma valve a globe ndi ma valve. Ndikuyembekeza kukuthandizani.

Valve ya tambala: imatanthawuza valavu yozungulira yokhala ndi chotsekeka ngati plunger. Pambuyo pa kuzungulira kwa 90 °, doko la tchanelo pa pulagi ya valavu limalumikizidwa kapena kupatulidwa ndi doko la mayendedwe pa valavu kuti mutsegule kapena kutseka. Mawonekedwe a pulagi ya valve akhoza kukhala cylindrical kapena conical. Mfundoyi ndi yofanana ndi ya valve ya mpira. Valve ya mpira imapangidwa pamaziko a valavu ya pulagi. Amagwiritsidwa ntchito kwambiri pofukula malo opangira mafuta, ndipo amagwiritsidwanso ntchito m'makampani a petrochemical.

ubwino:

①Kugwiritsidwa ntchito pafupipafupi, kutsegula ndi kutseka kwachangu komanso kosavuta.

②Kukana kwamadzimadzi kumakhala kochepa.

③ Zosavuta, zazing'ono, zolemera, zosavuta kuzisamalira.

④Kusindikiza kwabwino.

⑤ Kutengera malire a njira yoyika, njira yoyendetsera sing'anga imatha kukhala yosasunthika.

⑥Palibe kugwedezeka komanso phokoso lochepa.

cholakwika:

①Chivundikirocho ndi chachikulu kwambiri, ndipo torque yake ndi yayikulu kwambiri komanso yosasinthika mokwanira.

②Kulemera kwa thupi kumakhudzidwa, ndipo mawonekedwe ake ndi ochepa.

③Pogwiritsa ntchito kwenikweni, ngati valavu yayikulu ikugwiritsidwa ntchito, pulagi yolowera iyenera kugwiritsidwa ntchito, yomwe ingakhudze kusindikiza mosavuta.
