Mtundu wa valavu ya gulugufe wokhala ndi mpando wolimba
Kodi Mtundu wa Valavu ya Gulugufe Yokhazikika Yokhala ndi Malo Okhazikika ndi Chiyani?
Valavu Yokhazikika Yokhala ndi Gulugufe— yomwe imatchedwanso valavu ya gulugufe ya "concentric", "rabber lined" kapena "rabber seated" — ili ndi mpando wa rabara wolimba pakati pa mainchesi akunja a diski ndi khoma lamkati la thupi la valavu, zomwe zimapangitsa kuti kutseka kolimba ngati thovu kukhale kodalirika m'mafakitale osiyanasiyana.
Valavu yozungulira kotala yomwe imazungulira 90° kuti itsegule kapena kutseka madzi oyenda bwino. Disiki yozungulira — yoyikidwa pakati pa thupi la valavu — imagwira ntchito ngati njira yayikulu yotsekera, yolumikizidwa ku actuator kapena chogwirira kudzera mu shaft yapakati. Disiki ikamaliza kuzungulira kwathunthu kwa madigiri 90, valavu imagwira ntchito ngativalavu yodzipatula.
Ngati diski siizungulira mpaka kutembenuka konse kwa kotala, valavu imakhala yotseguka pang'ono - zomwe zimathandiza kuti igwire bwino ntchitomalamulo oyendetsera kayendedwe ka madzipa ngodya zosiyanasiyana zotsegulira.
Tchati cha CV/KV cha mtundu wa valavu ya gulugufe yokhazikika ikupezeka ngati mungafune.
Mtundu wa Lug — mawonekedwe akutsogolo ndi akumbali
Vavu ya Gulugufe ya Mtundu wa Lug— yopangidwira ntchito yomaliza mzere pomwe palibe flange yachiwiri yomwe ilipo. Mabowo a lug opangidwa ndi ulusi amaponyedwa mkati mwa valavu, ndi mabowo omangika ofanana ndi mawonekedwe a bolt a kukula kwa flange kofanana ndi kalasi yokakamiza. Mabowo amalumikizana mwachindunji ndi mabowo a lug kuchokera mbali iliyonse, kulola valavu kuchotsedwa mbali imodzi ya payipi popanda kusokoneza flange yotsutsana nayo.
Utumiki womaliza Wopepuka Yopanda kukonza Yotsika mtengo Kusindikiza mbali ziwiri
Zinthu zazikulu za mtundu wa valavu ya gulugufe yokhazikika
Kapangidwe kakang'ono — kulemera kochepa, malo ochepa osungiramo zinthu ndi malo oyikapo
Shaft yapakati, kutseka kolimba kwa thovu kozungulira mbali zonse ziwiri, njira iliyonse yoyikira
Thupi lonse lodzaza ndi chitoliro — kukana kuyenda bwino kwa madzi
Njira yolowera madzi yopanda mabowo — yosavuta kuyeretsa komanso yophera tizilombo toyambitsa matenda, yoyenera madzi akumwa
Thupi lokhala ndi rabara — madzi sagwirana ndi thupi lachitsulo
Kapangidwe ka ma diski opanda pin - kamachotsa njira zotayikira pa diski
ISO 5211 flange yapamwamba - yosavuta kuyimitsa yokha komanso kukonzanso kwa actuator
Kusankha kwa torque yotsika - kotsika mtengo
Maberiya okhala ndi PTFE — opanda kukonza, palibe mafuta ofunikira
Chovala choyikidwa — chosavuta kusintha, sichiwononga thupi, choyenera kugwiritsidwa ntchito kumapeto kwa mzere
DN32–DN600 Masayizi onse
Kapangidwe ka mpando wa manja a rabara
DN32–DN600 Kapangidwe ka chikwama cha rabara chofanana kamagwiritsidwa ntchito pamitundu yonse. Chikwamacho chimapangidwa bwino kuti chigwirizane ndi mizere ya thupi, zomwe zimapangitsa kuti chitsekeredwe bwino mbali zonse ziwiri komanso kusintha mosavuta popanda zida zapadera.
