Onani mavavu, amadziwikanso kutifufuzani ma valvekapena cheke mavavu, amagwiritsidwa ntchito kuteteza kubwerera kwa media mu payipi. Valavu ya phazi yochotsa pampu yamadzi imakhalanso m'gulu la ma cheke. Magawo otsegula ndi otseka amadalira kuyenda ndi mphamvu ya sing'anga kuti atsegule kapena kutseka okha, kuti ateteze sing'angayo kuti isayende chammbuyo. Ma valve owunikira ali m'gulu la ma valve odzichitira okha, omwe amagwiritsidwa ntchito makamaka pamapaipi pomwe sing'anga imayenda mbali imodzi, ndikungolola sing'anga kuyenda mbali imodzi kuteteza ngozi.
Malinga ndi kapangidwe kake, valavu yowunikira imatha kugawidwa m'mitundu itatu: valavu yokweza,valavu yoyenderandivalavu ya butterfly. Ma valavu okweza amatha kugawidwa m'magawo oyang'ana owoneka ndi ma valve opingasa.
Pali mitundu itatu yakusintha ma valve: valavu yoyang'ana ya lobe imodzi, ma valve oyendera maulendo awiri ndi ma check valves ambiri.
Valavu yoyang'ana gulugufe ndi valavu yowongoka, ndipo ma valavu omwe ali pamwambapa amatha kugawidwa m'mitundu itatu: valavu yolumikizira yolumikizidwa, valavu yoyang'anira kugwirizana kwa flange ndi valavu yoyendera.
Chidwi chiyenera kuperekedwa kuzinthu zotsatirazi pakuyika ma valve oyendera:
1. Osapangachekeni valavukunyamula kulemera kwa payipi, ndipo valavu yayikulu yoyang'ana iyenera kuthandizidwa paokha kuti isakhudzidwe ndi kukakamizidwa kopangidwa ndi payipi.
2. Pakuyika, tcherani khutu ku kayendetsedwe ka kayendedwe kapakati kayenera kukhala kogwirizana ndi njira ya muvi wovoteredwa ndi thupi la valve.
3. Vavu yokweza yoyimilira yoyang'ana paipi iyenera kuyikidwa paipi yoyima.
4. Valovu yokweza yopingasa yopingasa iyenera kuyikidwa paipi yopingasa. Kodi valavu yoyang'ana ofukula ndi chiyani? Ma valve owonetsetsa owonetsetsa amagwiritsidwa ntchito kwambiri m'makina omwe amafunika kuti ateteze kubwereranso kwa mauthenga, monga kutuluka kwa mpope, kumapeto kwa madzi otentha, komanso kumapeto kwa pampu ya centrifugal. Ntchito yake ndikuletsa zotsatira zomwe zingachitike kuchokera kumbuyo kwa sing'anga, mwachitsanzo, ngati kutuluka kwa mpope sikukhala ndi valavu yowunikira, madzi obwereranso othamanga kwambiri amachititsa kuti pakhale chiwopsezo chachikulu pampopi pamene mpope imasiya mwadzidzidzi; Ngati valavu yoyang'ana (valavu ya phazi) siinayikidwe kumapeto kwa pampu ya centrifugal, pampu iyenera kudzazidwa nthawi zonse pamene mpope watsegulidwa.
Mafunso ochulukirapo, mutha kulumikizana ndi TWS VALVE yomwe imapangavalavu ya butterfly yokhala pansi, valve pachipata, valavu, Y-strainer, etc.
