Mtengo wa fakitale DN50-DN2000 Valavu ya gulugufe yokhala ndi rabara yogulitsidwa
Kodi valavu ya gulugufe yolumikizidwa ndi Rubber ndi chiyani?
Valavu ya gulugufe yokhala ndi mphira Amatchedwanso valavu ya gulugufe ya "concentric", "yokhala ndi rabara" ndi "yokhala ndi rabara", ili ndi mpando wa rabara (kapena wolimba) pakati pa mainchesi akunja a diski ndi khoma lamkati la valavu.Vavu ya gulugufe imagwiritsidwanso ntchito ngati valavu yowongolera kuyenda kwa madzi, ngati diskiyo siizungulira mpaka kutembenuka konse kwa kotala, zikutanthauza kuti valavuyo yatsegulidwa pang'ono, titha kuwongolera kuyenda kwa madzi pogwiritsa ntchito ngodya zosiyanasiyana zotsegulira.
Valavu ya gulugufe yokhala ndi mphira,Nthawi zambiri amagwiritsidwa ntchito pamene valavu ili kumapeto kwa chitoliro chifukwa palibe flange yachiwiri yomangira ma stud. M'malo mwake, ma lug amaponyedwa pa valavu yokhala ndi mabowo omangika omwe amafanana ndi kapangidwe ka bolt malinga ndi kukula ndi kupanikizika kwa flange. Ma bolt amadutsa m'mabowo a flange ndipo amalumikizidwa m'mabowo omangika a lug.
Valavu ya gulugufe yokhala ndi mphira,Kapangidwe kakang'ono kwambiri kamene kali ndi kafupi kwambiri. Kamagwirizana pakati pa ma flange awiri, ndi ma stud omwe amadutsa kuchokera ku flange imodzi kupita ku ina. Valavu imagwiridwa pamalo ake ndikutsekedwa ndi gasket chifukwa cha mphamvu ya ma stud. Mtundu wa valavu ya gulugufe yokhala ndi mpando wolimba ndi njira yopepuka, yosakonza, yotsika mtengo, komanso yodalirika yogwiritsira ntchito zosiyanasiyana.
Zinthu Zazikulu za mtundu wa NORTECH reliable seat butterfly valve lug
Zinthu zazikulu yaValavu ya gulugufe yokhala ndi mphira
- Chovala chapamwamba cha ISO 5211 chimagwira ntchito bwino kuti chizigwira ntchito mosavuta komanso kuti chizigwiranso ntchito bwino.
- Ma torque ochepa ogwirira ntchito amapangitsa kuti ntchito ikhale yosavuta komanso kusankha ma actuator otsika mtengo.
- Ma bereari okhala ndi PTFE amapangidwira kuti asamavutike komanso kuti asawonongeke, mafuta odzola safunikira.
- Choyikamo mkati mwa thupi, choyikamo mkati chosavuta kusintha, palibe dzimbiri pakati pa thupi ndi mkati, choyenera kugwiritsidwa ntchito kumapeto kwa mzere.
- Kapangidwe kakang'ono kamapangitsa kuti pakhale kulemera kochepa, malo ochepa osungira ndi kuyika.
- Malo a shaft yapakati, 100% kulimba kwa thovu mbali zonse ziwiri, zomwe zimapangitsa kuti kuyika kukhale kovomerezeka mbali iliyonse.
- Thupi lonse la bore limapereka mphamvu zochepa kuti madzi azitha kuyenda bwino
- Palibe mabowo m'njira yolowera madzi, zomwe zimapangitsa kuti zikhale zosavuta kuyeretsa ndi kupha tizilombo toyambitsa matenda m'madzi akumwa ndi zina zotero.
