Valavu yowunikira, yomwe imadziwikanso kutivalavu yowunikira njira imodziNtchito yake yayikulu ndikuletsa kubwerera kwa njira yolumikizirana ndi kuteteza magwiridwe antchito otetezeka a zida ndi mapaipi.Ma valve oyezera madziamagwiritsidwa ntchito kwambiri mu mafuta, makampani opanga mankhwala, mankhwala ophera madzi, magetsi, zitsulo ndi zina.

Pali mitundu yambiri ya ma valve oyezera, malinga ndi kapangidwe kosiyana ndi mfundo yogwirira ntchito, akhoza kugawidwa m'magulu okweza, mtundu wa swing,valavu yoyezera gulugufe, mtundu wa mpira ndi zina zotero. Pakati pawo,valavu yoyezera kukwezaNdilo lodziwika kwambiri, lomwe lili ndi valavu yamkati yomwe ingakwezedwe, ndipo pamene sing'anga ikuyenda kuchokera ku cholowera kupita ku chotulukira, valavu imatsegulidwa pamwamba; pamene sing'anga ikuyenda mobwerera m'mbuyo, diski imatsekedwa kuti isabwerere m'mbuyo.

Pofuna kuonetsetsa kuti ntchito yanthawi zonse yavalavu yoyezera yosapanga dzimbirindi kukulitsa nthawi yake yogwira ntchito, kukonza tsiku ndi tsiku ndikofunikira kwambiri. Nazi zina mwazidziwitso za kukonza tsiku ndi tsiku za ma check valve:

1. Kuyang'anira nthawi zonse

Yang'anani mawonekedwe a valavu yowunikira nthawi zonse kuti muwone ngati pali ming'alu, kusintha kwa mawonekedwe, dzimbiri ndi zina. Nthawi yomweyo, yang'anani chisindikizo cha diski ndi mpando kuti muwonetsetse kuti palibe kutuluka kwa madzi.

2. Kuyeretsa

Yeretsani mkati ndi kunja kwa valavu yoyezera kuti muchotse dothi ndi zinyalala. Poyeretsa, chotsukira chopanda utsi chiyenera kugwiritsidwa ntchito kuti mupewe kugwiritsa ntchito zinthu zowononga monga asidi wamphamvu ndi alkali.

3. Sinthanitsani ziwalo zomwe zawonongeka

Ngati diski ya valavu, mpando ndi ziwalo zina za valavu yoyezera zapezeka kuti zawonongeka kapena zawonongeka kwambiri, ziyenera kusinthidwa pakapita nthawi. Sinthani ndi zofunikira zomwezo ndi zitsanzo za ziwalo zoyambirira kuti muwonetsetse kuti magwiridwe antchito a valavu sakukhudzidwa.

4. Mafuta odzola

Pa ma valve ena oyesera omwe amafunika kudzozedwa, mafuta oyenera kapena mafuta ayenera kuwonjezeredwa nthawi zonse kuti tsinde ndi mpando zikhale zodzozedwa bwino.

5. Chithandizo choletsa dzimbiri

Pa valavu yowunikira mzere yomwe imagwiritsidwa ntchito pamalo owononga, njira zotsutsana ndi dzimbiri ziyenera kutengedwa, monga kuphimba gawo loletsa dzimbiri ndikusankha zinthu zosagwira dzimbiri.

Kudzera mu njira zosamalira za tsiku ndi tsiku zomwe zili pamwambapa, mutha kuwonetsetsa kuti valavu yoyang'anira ikugwira ntchito bwino ndikuwonjezera nthawi yogwira ntchito, ndikupereka chitsimikizo champhamvu cha chitetezo cha zida ndi mapaipi.
