Mini Backflow Preventer
Kufotokozera:
Ambiri mwa anthu okhalamo samayikira chotchinga chakubwerera m'mapaipi awo. Ndi anthu owerengeka okha omwe amagwiritsa ntchito valavu yoyang'ana kuti apewe kubwerera. Chifukwa chake idzakhala ndi ptall yayikulu. Ndipo mtundu wakale woletsa kubwerera kumbuyo ndi wokwera mtengo komanso wosavuta kukhetsa. Choncho kunali kovuta kwambiri kugwiritsidwa ntchito kwambiri m’mbuyomu. Koma tsopano, timapanga mtundu watsopano kuti tithetse zonsezi. Anti drip mini backlow preventer yathu idzagwiritsidwa ntchito kwambiri mwa ogwiritsa ntchito wamba. Ichi ndi chipangizo chophatikizira mphamvu yamadzi kudzera mu kuwongolera kuthamanga kwa chitoliro kuti chikwaniritse njira imodzi. Idzateteza kubweza, kupewa mita yamadzi kutembenuzidwa ndi anti drip. Idzapereka madzi abwino akumwa komanso kupewa kuipitsa.
Makhalidwe:
1. Kuwongoka-kupyolera mu sotted kachulukidwe kachulukidwe kachulukidwe, kutsika kwamadzi otsika komanso phokoso lochepa.
2. Kapangidwe kakang'ono, kukula kochepa, kuyika kosavuta, sungani malo oyika.
3. Pewani kutembenuka kwa mita ya madzi ndi ntchito zapamwamba za anti-creeper idling,
drip tight ndi yothandiza pakuwongolera madzi.
4. Zida zosankhidwa zimakhala ndi moyo wautali wautumiki.
Mfundo Yogwirira Ntchito:
Amapangidwa ndi ma valavu awiri a chekeni kudzera mu ulusi
kulumikizana.
Ichi ndi chida chophatikizira champhamvu chamadzi kudzera pakuwongolera kukakamiza mu chitoliro kuti chikwaniritse njira ya oneway. Madzi akabwera, ma disks awiriwo adzakhala otseguka. Ikaima, idzatsekedwa ndi kasupe wake. Idzalepheretsa kutuluka kwa madzi ndikupewa mita yamadzi kutembenuzidwa. Vavu iyi ili ndi mwayi wina: Kutsimikizira chilungamo pakati pa wogwiritsa ntchito ndi Water Supply Corporation. Kuthamanga kukakhala kochepa kwambiri kuti sikulipirire (monga: ≤0.3Lh), valavu iyi idzathetsa vutoli. Malinga ndi kusintha kwa kuthamanga kwa madzi, mita ya madzi imatembenuka.
Kuyika:
1. Tsukani chitoliro musanalowetse.
2. Valavu iyi ikhoza kukhazikitsidwa molunjika komanso molunjika.
3. Onetsetsani kuti njira yoyendetsera sing'anga ndi momwe muvi amayendera mofanana mukayika.
