Valavu yagulugufe wapawiri wopangidwa ndi agulugufe amatchulidwa kutengera mawonekedwe ake awiri.Ndiye mawonekedwe a Double eccentric ndi otani?
Zomwe zimatchedwa kawiri eccentric, choyamba eccentric chimatanthawuza shaft ya valve yomwe ili pakatikati pa malo osindikizira, zomwe zikutanthauza kuti tsinde ili kumbuyo kwa nkhope ya valve.Kuphatikizika kumeneku kumapangitsa kuti mbali zonse ziwiri za mbale ya valve ndi mpando wa valavu zikhale zosindikizira, zomwe zimagonjetsa zofooka zomwe zimapezeka m'ma valve agulugufe, motero kuthetsa kuthekera kwa kutuluka kwamkati pamtunda wapamwamba ndi wapansi pakati pa shaft ndi valve. mpando wa valve.
Wina eccentricity amatanthauza valavu thupi pakati ndi tsinde olamulira kumanzere ndi kumanja kuchepetsa, ndiko kuti, tsinde amalekanitsa mbale gulugufe magawo awiri, wina mochuluka ndi wina zochepa.Eccentricity iyi ingapangitse mbale ya gulugufe potsegula ndi kutseka njira yotsegula ndi kutseka ikhoza kutsekedwa mwamsanga kapena pafupi ndi mpando wa valve, kuchepetsa kukangana pakati pa mbale ya valve ndi mpando wa valve wosindikizidwa, kuchepetsa kuwonongeka ndi kuphulika, kuchepetsa kutsegula ndi kutseka torque, ndi onjezerani moyo wautumiki wa mpando wa valve.
Kodi Mavavu Agulugufe Awiri Awiri Amasindikiza Bwanji?
Kuzungulira kwakunja kwa mbale ya valavu ndi mpando wosindikizidwa wa valavu yagulugufe wapawiri wopangidwa ndi agulugufe opangidwa ndi makina opangidwa ndi hemispherical pamwamba, ndipo mbali yakunja yozungulira ya mbale ya valve imafinya malo amkati ozungulira a mpando wosindikizidwa kuti apange mapindikidwe zotanuka kuti akwaniritse chotsekedwa. boma.Chisindikizo cha valavu yamagulugufe awiri eccentric ndi cha malo osindikizira, kutanthauza kuti kusindikiza pamwamba pa mbale ya valve ndi mpando wa valve ndi kukhudzana ndi mzere, ndipo mphete yosindikizira nthawi zambiri imapangidwa ndi mphira kapena PTFE.Chifukwa chake sichimalimbana ndi kuthamanga kwambiri, ndipo kugwiritsa ntchito pulogalamu yothamanga kwambiri kumayambitsa kutayikira.
Kodi Gawo Lalikulu la Double Eccentric Butterfly Valve Ndi Chiyani?
Kuchokera Pachithunzi Pamwambapa, Titha Kuwona Bwino Kuti Magawo Akuluakulu A Double Eccentric Butterfly Valve Ali Ndi Zinthu Zisanu Ndi Ziwiri Izi:
Thupi: Nyumba yaikulu ya valve, yomwe nthawi zambiri imapangidwa ndi chitsulo chosungunuka, chitsulo cha ductile, kapena chitsulo chosapanga dzimbiri, imapangidwa kuti ikhale ndi zigawo zamkati za valve.
Chimbale: Chigawo chapakati cha valavu chomwe chimazungulira mkati mwa thupi la valve kuti chiteteze kutuluka kwa madzi.Chimbalecho nthawi zambiri chimapangidwa ndi chitsulo chosungunuka, chitsulo choponyedwa kapena mkuwa ndipo chimakhala ndi mawonekedwe osalala kapena opindika kuti agwirizane ndi mawonekedwe a valavu.
Shaft Bearings: mayendedwe a shaft amapezeka mu thupi la valve ndikuthandizira shaft, kuti azitha kuzungulira bwino ndikuchepetsa kukangana.
Mphete Yosindikizira: mphete yosindikizira ya rabara imayikidwa pa mbale ya valve ndi mbale yoponderezedwa ndi zomangira zitsulo zosapanga dzimbiri, ndipo chiŵerengero chosindikizira cha valve chimasinthidwa posintha zomangira.
Kusindikiza Mpando: ndi gawo la valve yomwe imasindikiza disc ndikupewa kutuluka kwamadzi kudzera mu valve ikatsekedwa.
Shaft yoyendetsa: imalumikiza cholumikizira ku nthiti ya valve ndikutumiza mphamvu yomwe imasuntha chowotcha cha valve pamalo omwe mukufuna.
Actuator: imayang'anira malo a disc mkati mwa thupi la valve.Ndipo kawirikawiri wokwera pamwamba pa valavu thupi.
Gwero la Chithunzi: Hawle
Kanema wotsatirawa akupereka mawonekedwe owoneka bwino komanso atsatanetsatane a kapangidwe kake ndi mawonekedwe a valavu yagulugufe wapawiri.
Ubwino Ndi Kuipa Kwa Double Eccentric Butterfly Valve
Ubwino:
1 Kupanga koyenera, kapangidwe kaphatikizidwe, kosavuta kukhazikitsa ndi kuphatikizira, kusinthasintha kwa magwiridwe antchito, kupulumutsa antchito, kosavuta, kukonza kosavuta.
2 Mapangidwe a eccentric amachepetsa kukangana kwa mphete yosindikiza ndikuwonjezera moyo wautumiki wa valavu.
3 Wosindikizidwa kwathunthu, kutayikira kwa ziro.Itha kugwiritsidwa ntchito pamalo owuma kwambiri
4 Sinthani zinthu za valavu mbale chisindikizo, gulugufe mbale, kutsinde, etc., amene angagwiritsidwe ntchito zosiyanasiyana TV ndi kutentha osiyana.
5 Mapangidwe a chimango, mphamvu yayikulu, malo akulu osefukira, kukana koyenda pang'ono
Zoyipa:
Chifukwa kusindikiza ndi mawonekedwe osindikizira, malo osindikizira a gulugufe ndi mpando wa valavu amalumikizana mzere, ndipo kusindikiza kumapangidwa ndi kutsekedwa kwa zotanuka chifukwa cha gulugufe kukakamiza mpando wa valavu, kotero kumafuna kutseka kwakukulu. udindo ndipo ali ndi mphamvu yochepa yothamanga kwambiri komanso kutentha kwakukulu.
