Avalavu ya butterflyndi mtundu wa chipangizo chowongolera otaya, chomwe chimaphatikizapo diski yozungulira kuti igwiritse ntchito madzi omwe akuyenda.Mu malo ofukula a gulugufe valavu, pali zitsulo ofotokoza chimbale kuti ntchito kutseka luso madzimadzi ikuyenda.Ntchito yotseka ya valve iyi ndi yofanana ndendende ndi kutseka kwa valve ya mpira.
Poyerekeza ndi valavu ya mpira woyandama, valavu iyi ili ndi izi:
Opepuka;choncho sichifuna chithandizo chochuluka.
Poyerekeza ndi ma valve ena ofanana ndi mapangidwe osiyanasiyana, mtengo wake ndi wotsika.
Valve ya butterfly ndi yodalirika komanso yotseka njira ziwiri, yomwe imagwiritsidwa ntchito kwambiri pazakudya, kupanga zombo, ndi mafakitale ena.Poyerekeza ndi ma valve ena, kukhazikitsa ma valve a butterfly ndi njira yotsika mtengo.Potseka diski, valavu ya butterfly ingathandizenso kutsogolera kutuluka ndi kutseka madzi / gasi.
Momwe mungakonzere ndikusamalira mavavu agulugufe pamapaipi osiyanasiyana?
Malangizo otsatirawa pakukonza ma valve a butterfly atha kuperekedwa kwa inu kuti muwonetsetse:
Mavavu agulugufe amafunika kusamalidwa ndi kukonzedwa nthawi zonse akamagwira ntchito m'malo osiyanasiyana kwa nthawi.Kukonza zonse kungathe kugawidwa m'makonzedwe ang'onoang'ono, kukonzanso kwapakatikati, ndi kukonzanso kwakukulu.
Kusanthula kwachindunji kumadalira momwe chilengedwe chikuyendera.Chifukwa mafakitale osiyanasiyana amafunikira njira zosiyanasiyana zokonzera ndi kukonza, mwachitsanzo, pakukonza mapaipi amakampani a petrochemical, kuthamanga kwa mapaipi kumafunika kukhala kotsika kuposa PN16MPa, ndipo kutentha kwapakati kumakhala kotsika kuposa 550 ° C.Kukonzekera kosiyanasiyana kumafunika pamayendedwe osiyanasiyana akuthupi ndi amankhwala pamapaipi.
Njira yaying'ono yokonza mavavu agulugufe wa mapaipi, kuphatikiza kuyeretsa ma nozzles ndi makapu amafuta, kusintha mphete za o, ulusi woyeretsa ndi ma valve, kuchotsa zinyalala mu valavu, zomangira zomangira, ndi kukonza magudumu am'manja.Zonsezi zitha kugwiritsidwa ntchito ngati kukonza kokonzekera.Kukonzekera kwapakatikati: kuphatikizapo kukonzanso zinthu zazing'ono, kukonzanso ziwalo zoyera, kukonza thupi la valve, mchenga wa zisindikizo, kuwongola tsinde la valve, ndi zina zotero. Zinthuzi zingagwiritsidwe ntchito kukonzanso fakitale.Kukonzekera kolemera: Kuphatikizidwa mu ntchito yokonza yapakati, kulowetsa tsinde la valve, kukonza mabakiti, kulowetsa akasupe ndi zisindikizo.Izi zikafunika, valavu ya gulugufe imawonongeka kwambiri.
Pofuna kupewa dzimbiri ndi mafuta, ma valve a butterfly ayenera kusamalidwa bwino.
Pamwamba pa valavu, pali mafuta opaka mafuta.Izi sizingawoneke pamene valve ifika.Onetsetsani kuti mumapaka mafuta pakhosi la valve nthawi ndi nthawi mpaka mafuta ochulukirapo atuluka.
Mu gearbox, mutha kugwiritsa ntchito mafuta a lithiamu pokonza.
Mutha kugwiritsa ntchito chilichonse chopangidwa ndi silicon / lubricant kuti muyeretse mosavuta magawo onse a valve.
Ngati simugwiritsa ntchito pafupipafupi, chonde yesani kuzungulira kapena kuyendetsa valavu yamafuta kamodzi pamwezi.
Ife ndifeothandizira agulugufe.Chonde omasuka kulankhula nafe ngati mukufuna zinthu zathu.
