Ubwino Wathu Wathu Wosakwera Stem Ofewa Wosindikizira Chipata
1) Chisindikizo chapamwamba cha valavu chimasindikizidwa ndi mphete zitatu za "O" -zooneka ngati mphira, ndipo mphete ziwiri za "O" zooneka ngati mphira zimatha kusinthidwa popanda kuyimitsa madzi.
2) Thupi la valavu ndi boneti zimatengera "O" mtundu wa mphete yosindikizira ya rabara, yomwe imatha kudzisindikiza yokha.
3) Valavu ikatsegulidwa kwathunthu, mbale ya valve ndi yayikulu kuposa m'mimba mwake ya valavu, pansi pa valavu ndi yosalala popanda chipata cha chipata, ndipo mphamvu yolimbana ndi kutuluka ndi yaying'ono, yomwe imapewa chodabwitsa kuti mbale ya valve ndi yaing'ono. osatsekedwa mwamphamvu chifukwa cha zinyalala zomwe zimatsekereza gasket.
4) Mtedza wa tsinde la valve ndi mbale ya pachipata zimagwirizanitsidwa ndi T-slot, yomwe imakhala ndi mphamvu zambiri, ndipo mphamvu yowonongeka pakati pa mbale ya valve ndi thupi la valve ndi yaying'ono kwambiri, ndipo moyo wautumiki ndi wautali.
5) Anti-dzimbiri ndi odana ndi dzimbiri mankhwala utenga electrostatic kupopera mankhwala sanali poizoni epoxy utomoni otentha-kusungunuka solidification ufa.Ufawu uli ndi certification ya WRAS ndi NSF, yomwe imachotsa kuipitsidwa kwachiwiri kumtundu wamadzi ndikupanga madzi kukhala oyera.
