1. Dulani ndi kumasula cholumikiziracho

Iyi ndiyo ntchito yofunikira kwambiri ya valavu. Nthawi zambiri, valavu yokhala ndi njira yolunjika yoyendera imasankhidwa, ndipo kukana kwake kuyenda kumakhala kochepa.

Ma valve otsekedwa pansi (Ma valve a globeMa valve opopera madzi (plunger valves) sagwiritsidwa ntchito kawirikawiri chifukwa cha njira zawo zoyendera madzi zomwe zimagwedezeka komanso kukana madzi kuyenda bwino kuposa ma valve ena. Pamene kukana madzi kuyenda bwino kumaloledwa, valavu yotsekedwa ingagwiritsidwe ntchito.

2. Ckayendedwe ka kayendedwe ka mphamvu

Kawirikawiri, valavu yomwe ndi yosavuta kusintha kayendedwe ka madzi imasankhidwa ngati chowongolera kayendedwe ka madzi. Vavu yotseka pansi (mongavalavu yapadziko lonse) ndi yoyenera pachifukwa ichi chifukwa kukula kwa mpando wake kumagwirizana ndi kukwapula kwa chiwalo chotseka.

Ma valve ozungulira (Ma valve a pulagi, mavavu a gulugufe, mavavu a mpira) ndi ma valve opindika (ma valve opindika, ma valve a diaphragm) angagwiritsidwenso ntchito powongolera kugwedezeka, koma nthawi zambiri amagwiritsidwa ntchito kokha mkati mwa ma diameter ochepa a ma valve.

Valavu ya chipata imagwiritsa ntchito chipata chooneka ngati diski kuti ipange kayendetsedwe kodulira kupita ku malo otseguka a valavu yozungulira. Imatha kuwongolera bwino kuyenda kwa madzi pokhapokha ngati ili pafupi ndi malo otsekedwa, kotero nthawi zambiri siigwiritsidwa ntchito powongolera kuyenda kwa madzi.

3. Kubwerera m'mbuyo ndi kusuntha

Malinga ndi zosowa za kubweza ndi kusuntha, valavu yamtunduwu imatha kukhala ndi njira zitatu kapena kuposerapo.Ma valve atatu a mpirandi oyenera kwambiri pa izi. Chifukwa chake, ma valve ambiri omwe amagwiritsidwa ntchito pobweza ndi kugawa kayendedwe ka madzi amasankha imodzi mwa ma valve awa.

Koma nthawi zina, mitundu ina ya ma valve ingagwiritsidwenso ntchito pobwezeretsa ndi kusuntha malinga ngati ma valve awiri kapena angapo alumikizidwa bwino.

4. Pakatikati yokhala ndi tinthu tomwe timapachikidwa

Ngati pali tinthu tomwe timapachikidwa mu sing'anga, ndibwino kugwiritsa ntchito valavu yokhala ndi mphamvu yopukuta pa kutsetsereka kwa chotsekacho pamwamba pa chotsekacho.

Ngati mayendedwe a chotseka cha valavu kumbuyo ndi kumbuyo akuyenda molunjika, chingathe kugwira tinthu tating'onoting'ono. Chifukwa chake, valavu iyi ndi yoyenera kokha pa malo oyeretsera pokhapokha ngati zinthu zotsekera pamwamba zimalola tinthu tating'onoting'ono kuti tilowe. Ma valavu a mpira ndi ma valavu a pulagi amakhala ndi mphamvu yopukuta pamwamba potsekera panthawi yotsegula ndi kutseka, kotero ndi oyenera kugwiritsidwa ntchito pa malo otsekera ndi tinthu tating'onoting'ono tomwe tapachikidwa.
