Mavavu a Butterfly
Titanium B367 Gr.C-2 API Standard Flanged Butterfly Valve
Kuchepetsa katatu kumatanthawuza kuwonjezera kuwonjezereka kowonjezera kwa angular pamaziko a kapangidwe kaŵirikaŵiri kotchulidwa pamwambapa, ngakhale kusindikiza pamwamba pa valve ya butterfly ndi yokhotakhota komanso yozungulira. Maonekedwe a kamangidwe kameneka ndi kusindikiza m'mphepete mwa mbali ya gulugufe kumalo ozungulira akunja, ndi kusindikiza mbali yamkati ya mpando wa valve yosindikizira kuti ikhale pamwamba. Panthawiyi, gawo losindikiza la valavu ya butterfly lakhala elliptical, ndipo mawonekedwe a kusindikiza pamwamba pa mbale ya butterfly ndi asymmetrical. Chifukwa cha malo osindikizira ozungulira, mbali yaikulu ya gulugufeyo imasiyanitsidwa ndi shaft tsinde ya valve ndikukankhira mmwamba ku mpando wa valavu pambali yaikulu yokhotakhota, pamene mbali yaing'ono ya gulugufe imakanikizidwa pansi kupita ku mpando wa valve. pamodzi ndi malo ang'onoang'ono okhotakhota. Kusindikiza pakati pa mphete yosindikizira ya gulugufe ndi mpando wa valavu sikudalira mapindikidwe otanuka a mpando wa valve, koma kwathunthu pa kukanikiza kwa malo okhudzana kuti akwaniritse kusindikiza. Choncho, kutsegula ndi kutseka kwa valavu ya agulugufe atatu osasunthika kwenikweni, ndipo pamene mphamvu yotseka ikuwonjezeka, valavu imatseka molimba kwambiri.

Mpando wa valavu wa agulugufe atatu eccentric amapangidwa ndi zitsulo zosapanga dzimbiri komanso mapepala a graphite. Kapangidwe kameneka kamatha kulepheretsa kukhudzidwa kwa zinthu zing'onozing'ono zolimba mkatikati ndi kuluma komwe kungasindikizidwe chifukwa cha kuwonjezeka kwa kutentha. Ngakhale patakhala kuwonongeka pang'ono, sipadzakhala kutayikira, komwe sikungaganizidwe kwa valve ya butterfly yapawiri kapena ma valve ena atatu agulugufe.
Mphete yosindikizira ya valavu yagulugufe atatu eccentric imatha kunenedwa kuti ndi yapadera. Sikuti mpando waukulu wa valve ungasinthidwe, komanso chifukwa chosindikizira pamwamba pa mbale ya butterfly sichidziimira pa mbale ya butterfly, malo osindikizira a gulugufe amatha kusinthidwanso. Izi zikutanthauza kuti pamene malo osindikizira a gulugufe awonongeka, palibe chifukwa chothamangira ku fakitale yopanga kapena kusokoneza valve. Malo osindikizira okha a gulugufe ayenera kusinthidwa. Izi sizimangochepetsa kwambiri ndalama zolipirira, komanso zimachepetsa kwambiri maola osamalira, kulimba kwa kukonza, komanso zovuta.

Mapulogalamu
Ma valve atatu a butterfly eccentric, monga crystallization ya zamakono zamakono mu ma valve, amasonyeza mphamvu za ma valve osiyanasiyana ndikupewa kufooka kwa ma valve osiyanasiyana, mosakayikira adzalandira chidwi chowonjezeka kuchokera kwa ogwiritsa ntchito ndi okonza. Kupanikizika kwake kwakukulu kumatha kufika mapaundi a 2500, kukula kwake kumatha kufika mainchesi 48, ndipo kumatha kufananizidwa ndi ma clamps, lugs, ma flanges, mafupa a mphete, ma welds a matako, ma jekete, kutalika kosiyanasiyana, etc. Komanso, chifukwa chamitundu yosiyanasiyana Kusankha kwazinthu, kumatha kufananizanso momasuka ndi kutentha kwakukulu komanso kotsika, komanso ma media osiyanasiyana owononga monga asidi ndi alkali. Makamaka pankhani ya mainchesi akulu, ndi mwayi wake wa kutayikira kwa zero, nthawi zonse imasintha zipata zazikulu ndi ma valve a mpira mumavavu otseka. Mofananamo, ndi ntchito yake yabwino yolamulira, imakhalanso ndi nthawi zonse m'malo mwa ma valve akuluakulu a globe poyendetsa ma valve. M'malo mwake, amagwiritsidwa ntchito pamapaipi ofunikira osiyanasiyana monga kuwongolera njira m'mafakitale akuluakulu monga kutulutsa mafuta ndi gasi, nsanja zakunyanja, kuyenga mafuta, mafuta a petrochemicals, mankhwala ophatikizika, komanso kupanga mphamvu, kuphatikiza China. Mavavu atatu eccentric gulugufe chimagwiritsidwa ntchito mapaipi mafakitale monga zitsulo, mphamvu, petrochemicals, madzi ndi ngalande, ndi zomangamanga tauni kumene kutentha sing'anga ndi ≤ 425 ℃. Amagwiritsidwa ntchito kuwongolera kutuluka ndi kudula madzimadzi.
