Chifukwa cha mawonekedwe ake osavuta, kukhazikitsa kosavuta, kulemera kwake, komanso kutsegula ndi kutseka mwachangu,valavu butterflyamagwiritsidwa ntchito kwambiri m'mafakitale ndi apakati pakatikati komanso pamapaipi otsika.Ngati valavu yogwiritsidwa ntchito kwambiri yotereyi imatha kutalikitsa moyo wake wautumiki, idzatulutsa phindu lalikulu kwa ogwiritsa ntchito valve ya butterfly.
Kusankhidwa koyenera kwa valve ya butterfly yomwe ikugwira ntchito kumapereka chofunikira pa moyo wautumiki wa valavu ya butterfly pamene kusankha koyenera kwapangidwa.Mavavu agulugufe osiyanasiyana amagwiritsidwa ntchito pazochitika zosiyanasiyana, ndipo ichi ndi chifukwa cha maonekedwe a mitundu yonse ya zizindikiro ndi zitsanzo za ma valve a butterfly.Posankha mtundu, simungagwiritse ntchito mwachimbulimbuli mavavu agulugufe okwera mtengo.Zosiyanasiyanavalavu butterflyza mafotokozedwe osiyanasiyana ndizofunikira, kotero palibe chabwino kapena choipa pakati pawo, choyenera kapena chosayenera.Mikhalidwe yogwirira ntchito yoyenera kugwiritsidwa ntchito ndi yabwino kwambiri.
Kuyika koyenera: Ngakhale kukhazikitsa valavu ya butterfly ndikosavuta, sikungasamalidwebe.Kuwonongeka kulikonse, kupindika, kapena kupindika kwa zigawozo kumakhudza momwe ntchito ikuyendera.Kugwiritsa ntchito moyenera ndikofunikira.Mwachitsanzo, simungagwiritse ntchito choyatsira moto kapena torque wrench potsegula ndi kutseka valavu ya gulugufe.Nthawi zambiri, kapangidwe kake kayenera kukhala koyenera.Pamene sitingathe kutsegula ndi kutseka valavu ya butterfly, momwe tingakulitsire moyo wa gulugufe?Chifukwa chake chiyenera kufufuzidwa choyamba, kutseka mokakamiza kudzafupikitsa kwambiri moyo wautumiki wa valve.
Kapangidwe koyenera Akagwiritsidwa ntchito m'malo ena apadera, wogwiritsa ntchito amatha kukambirana ndi wopanga mapulani oyenera.Ngati mankhwala ochiritsira akugwiritsidwabe ntchito, sizingakhale zothandiza kugwiritsa ntchito ma valve a butterfly.
M'mapaipi, ngati chiwongolero chakutali kapena kutseka pafupipafupi kumafunika, mavavu agulugufe amagetsi ndi ma valve agulugufe wa pneumatic amasankhidwa.Chifukwa cha kutsegulidwa pafupipafupi ndi kutseka ndi zochitika zapadera zogwirira ntchito, chithandizo chapadera chapadera nthawi zambiri chimafunika.Pamanjavalavu butterflyndi ndodo zopukutidwa sizingayikidwe mwachindunji ndi ma valve actuators.Kawirikawiri, chithandizo chotsatirachi chiyenera kuchitidwa: tsinde la valve limakhuthala kuti tsinde la valve lisagwedezeke ndi kupunduka chifukwa cha kugwedezeka panthawi yotsegula ndi kutseka;makina olongedza amatengera njira monga kuyika mphete za spacer, akasupe amalipiro amalingaliro, ndikuyika mphete za O kuti awonjezere makina onyamula pansi pa ntchitoyi.
Zomwe zili pamwambazi ndizochitika zochepa zomwe zimasonkhanitsidwa popanga ma valve ndi kugwiritsira ntchito, kuyembekezera kupereka chithandizo choyenera kwa ogwiritsa ntchito ma valve omwe akufunikira.
