Check valve ndi chiyani?
Chongani valavu ndi mtundu wa vavu pa cholinga uni-directional, komanso ngati mavavu osabwerera.
Onani Vavundi valavu yosavuta komanso yodalirika yokhala ndi mpira wozungulira ngati gawo lokhalo losuntha kuti liletse kuyenda mozungulira.Chifukwa cha kayendedwe kake kosavuta komanso kopanda kukonza bwino valavu imatchulidwa kawirikawiri ndipo imagwiritsidwa ntchito m'malo okwera madzi otayira pansi pamadzi.Mpando wa valve wodzaza ndi valavu umapangidwa mwapadera kuti mpira ukhale wotsekemera popanda kulowa mumpando wa valve.Pogwiritsa ntchito vacuum kapena anti-flooding valve, mpira "woyandama" m'malo mwa "kumira" umagwiritsidwa ntchito.
fufuzani ma valvekhalani ndi mpira womwe umakhala pampando, womwe uli ndi bowo limodzi lokha.Imagwira ntchito pogwiritsa ntchito mpira womwe umayenda m'mwamba ndi pansi mkati mwa valve.Mpandowo umapangidwa kuti ugwirizane ndi mpirawo, ndipo chipindacho chimapangidwa mozungulira kuti chiwongolere mpirawo pampandowo kuti usindikize ndikuyimitsa kutuluka kobwerera.Pamene kupanikizika kumbuyo kwa mpando kupitirira pamwamba pa mpira, madzi amaloledwa kudutsa mu valve.Koma kukanikiza pamwamba pa mpirawo kukadutsa pansi pa mpando, mpirawo umabwerera kukapuma pampando, kupanga chisindikizo chomwe chimalepheretsa kubwereranso.Mpira umayenda m'mwamba ndi pansi mkati mwa valavu malingana ndi kutuluka ndi kusindikiza pampando wopangidwa ndi makina pamene palibe kutuluka kapena kubwereranso komwe kumachitika ndikusindikiza pampando kuti asiye kubwereranso.
Zinthu zazikulu za valavu ya cheki
Features ndi ubwino waOnani Vavu
- kuletsa reverse flow,kapangidwe kopanda kukonza, suitbale kwa malo onyamulira madzi oyipa apansi pamadzi.
- *Mpando wa valavu wokhala ndi zingwe zonse umapangidwa mwapadera kuti mpirawo ukhale wothina popanda kulowa mu valavu.
- *NortechOnani Vavundi odziyeretsa, pamene mpira umazungulira panthawi yogwira ntchito zomwe zimachotsa chiopsezo cha zonyansa zomwe zimakakamira pa mpirawo.
- * Kubowola kokwanira komanso kosalala kumapangitsa kuyenda kwathunthu ndi kutsika kwapakatikati ndikuchotsa chiwopsezo cha ma depositi pansi chomwe chingalepheretse kutseka kolimba. mpira kuti usatseke pampando.Mipira ya polyurethane ndi yoyenera kwa abrasive media ndipo pamene mipira yolemetsa yosiyana imafunika kupewa phokoso ndi nyundo yamadzi.
