Kodi valavu ya butterfly yokhala ndi Rubber ndi chiyani?
Vavu ya butterfly yokhala ndi mphira imatchedwanso "concentric", "rabala yokhala ndi mphira" ndi "rabara yokhala" butterfly valve, ili ndi mpando wa rabara (kapena wokhazikika) pakati pa kunja kwa diski ndi khoma lamkati la valve.Valavu ya butterfly imagwiritsidwanso ntchito ngati valavu yowongolera kuthamanga, ngati diskiyo sizungulira mpaka kotala, zikutanthauza kuti valavu yatseguka pang'ono, titha kuyang'anira kutuluka kwamadzi ndi ngodya zosiyanasiyana zotsegulira.
Vavu ya butterfly yokhala ndi mphira,nthawi zambiri amagwiritsidwa ntchito pomwe valavu ili kumapeto kwa chitoliro popeza palibe 2nd flange yotetezera ma studs.M'malo mwake, zipilala zimaponyedwa pa valavu yokhala ndi mabowo okhomedwa omwe amafanana ndi mtundu wa bawuti wa kukula ndi kukakamiza kwa flange.Maboti amadutsa m'mabowo a flange ndipo amakongoleredwa m'mabowo otsekedwa a lug.
Vavu ya butterfly yokhala ndi mphira,mawonekedwe ophatikizika kwambiri okhala ndi nkhope zazifupi ndi maso. amakwanira pakati pa ma flanges awiri, okhala ndi zingwe zodutsa kuchokera ku flange imodzi kupita kwina.Valavu imagwiridwa ndikusindikizidwa ndi gasket chifukwa cha kugwedezeka kwa ma studs. Mtundu wokhazikika wokhala ndi butterfly valve lug ndi wopepuka, wopanda kukonza, wotchipa, komanso wodalirika yothetsera ntchito zosiyanasiyana.
Zofunika Zazikulu za mtundu wa lug wa gulugufe wa NORTECH
Mbali zazikulu zaVavu ya butterfly yokhala ndi mphira
- ISO 5211 top flange ndiyosavuta kugwiritsa ntchito makina opangira makina komanso kubwezeretsanso makina oyendetsa.
- Ma torque otsika amapangitsa kuti ntchito ikhale yosavuta komanso kusankha koyendetsa ndalama.
- PTFE mizere mayendedwe amapangidwa kuti odana ndi kukangana ndi kuvala, palibe mafuta chofunika.
- Akalowa m'thupi, liner yosavuta kusintha, palibe dzimbiri pakati pa thupi ndi akalowa, oyenera kutha ntchito mzere.
- Kumanga kocheperako kumabweretsa kulemera kochepa, malo ochepa posungira ndi kuyika.
- Centric shaft position, 100% bi-directional bubble tightness, yomwe imapangitsa kuyika kovomerezeka kulikonse.
- Thupi lathunthu limapereka kukana kutsika kwakuyenda
- Palibe ma cavities mu ndime yotaya, zomwe zimapangitsa kuti zikhale zosavuta kuyeretsa ndi kupha tizilombo toyambitsa matenda amadzi amchere etc.
