Soft Seal Manual Operated Butterfly Valve fakitale yaku China yokhala ndipamwamba kwambiri
Kodi valavu ya Butterfly ndi chiyani?
Gulugufe Valve, imatchedwanso "concentric", "rabala yopangidwa ndi mphira" ndi "rabara yokhala" butterfly valve, ili ndi mpando wa rabara (kapena wokhazikika) pakati pa kunja kwa disc ndi khoma lamkati la valve.
Valavu ya butterfly ndi valavu yotembenukira kotala yomwe imazungulira madigiri 90 kuti mutsegule kapena kutseka kutulutsa kwa media.Lili ndi diski yozungulira, yomwe imadziwikanso kuti butterfly, yomwe imapezeka pakatikati pa thupi lomwe limagwira ntchito ngati njira yotseka valve.Chimbalecho chimalumikizidwa ndi actuator kapena chogwirira kudzera mu shaft, yomwe imadutsa kuchokera ku diski kupita pamwamba pa thupi 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.
Gulugufe valavu,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.
Zofunika Kwambiri za NORTECH butterfly valve
Mbali zazikulu za ma valve a butterfly
- 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.
- 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.

Kodi valavu yagulugufe yokhala pansi yokhazikika imagwiritsidwa ntchito kuti?
Valve ya butterfly amagwiritsidwa ntchito kwambiri mu
- Malo opangira madzi ndi zinyalala
- Ma conveyor a pneumatic, ndi ntchito za vacuum
- Zopopera mpweya, gasi ndi desulphurization zomera
- Makampani opanga moŵa, distilling, ndi chemical process process
- Mayendedwe ndi youma chochuluka akugwira
- Makampani opanga magetsi
