Valve yowunikira iyenera kukhazikitsidwa potuluka pampu komanso kutsogolo kwa valve yowongolera kuti ikonzedwe.Kawirikawiri, potulukira koyamba papopa ndi kulumikiza kofewa (chiwopsezo chogwedeza), chotsatiridwa ndi valavu, ndiyeno valavu yotchinga (monga valve butterfly, valve valve, valve stop, etc.).
1. Ikani valavu yoyang'anira kaye kenako valavu yachipata kapena valavu yagulugufe
Ubwino: imatha kuteteza valavu yoyendera, makamaka pamapampu ofanana.Pampu imodzi ikayamba ndipo pampu ina ikuyamba, mphamvu yake imayendetsedwa ndi valve yachipata kapena valavu ya butterfly.
Zoyipa: ndani angateteze valavu yachipata kapena valavu?Panali nkhani yakuti mbale ya valve ya butterfly valve inasweka.
2. Ikani valavu yachipata kapena valavu ya butterfly musanayambe cheke
Ubwino: imatha kuteteza valavu yagulugufe kapena valavu yachipata, ndipo mphamvu yamphamvu imayendetsedwa ndi valavu yoyendera
Zoyipa: ndani angateteze valavu ya cheke?Valve yowunikira imatsegulidwa ndikutsekedwa ndi kusiyana kwapakati.Ngati kuthamanga kwamutu kuli kwakukulu, kudzatsekedwa ndipo kuthamanga kwapope kudzatsegulidwa.Ngati kuyenda komwe kumagwiritsidwa ntchito kumakhala kosasunthika, valavu yowunikira idzatsegulidwa ndi kutsekedwa mobwerezabwereza, zomwe zidzakhudza moyo wautumiki wa valve check.
