M'munda wa ma valve a mafakitale, ma valve a butterfly amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga mafuta ndi gasi, chithandizo cha madzi, kukonza mankhwala, ndi zina zotero. valavu ya butterfly. M'kufananitsa kwakukuluku, tiwona mozama mapangidwe, ubwino, kuipa ndi kugwiritsa ntchito ma valve awiriwa.
Vavu yagulugufe ya Double Offset
Monga momwe dzinalo likusonyezera, mavavu agulugufe omwe ali ndi magawo awiri ali ndi zosinthika ziwiri: choyamba ndi kutsetsereka kwa shaft, ndiko kuti, kutsika kwa shaft axis kuchokera pakatikati pa payipi, ndipo njira yachiwiri ndiyo kutsekeka kwa chisindikizo, ndiko kuti, geometry ya valve disc chisindikizo. Kapangidwe kameneka kali ndi ubwino ndi kuipa kwake.
Ubwino wa double eccentric butterfly valve
1. Kuchepetsa kuvala
Cholinga cha shaft eccentricity design ndikuchepetsa kukangana pakati pa mbale ya valve ndi mpando wa valve panthawi yotsegula ndi kutseka, potero kuchepetsa kuvala ndi kuchepetsa chiopsezo cha kutayikira. Itha kuwonjezeranso moyo wa valavu ya butterfly ndikuchepetsa ndalama zolipirira.
2. Kusindikiza kowonjezera
Kukhazikika kwachiwiri kumapangitsa kuti malo osindikizira agwirizane ndi mpando wa valve pokhapokha pomaliza kutseka, zomwe sizimangotsimikizira chisindikizo cholimba, komanso zimayendetsa bwino sing'anga.
3. Torque yochepetsedwa
Mapangidwe a double offset amachepetsa friction coefficient, zomwe zimachepetsa mphamvu yotsegula ndi kutseka valve ya butterfly.
4. Kusindikiza kuwirikiza kawiri
Mavavu agulugufe omwe ali ndi ma eccentric atha kusindikiza kuwirikiza kawiri, kulola kuyenda kozungulira, ndipo ndi osavuta kuyiyika ndikugwiritsa ntchito.
Kuipa kwa mavavu agulugufe awiri eccentric:
1. Mtengo wapamwamba
Mapangidwe apamwamba ndi zida za ma valve agulugufe omwe ali ndi ma eccentric eccentric agulugufe nthawi zambiri amabweretsa ndalama zambiri zopangira poyerekeza ndi ma valve agulugufe wapakati.
2. Kuthamanga kwambiri kwa madzi kumataya
Chifukwa cha valavu yokhuthala iwiri, mpando wa valve wotuluka, ndi tinjira tating'ono, mphamvu yamadzi imatayika kudzera mu valve yagulugufe imatha kuwonjezeka.
3. Kutentha kochepa
Mavavu agulugufe ang'onoang'ono amatha kukhala ochepa pogwira kutentha kwambiri kapena kutentha kwambiri chifukwa zipangizo zomwe zimagwiritsidwa ntchito sizingapirire kutentha kwambiri.
Valve yagulugufe ya Triple Offset
Valavu yagulugufe katatu imayimira chitukuko china cha mapangidwe agulugufe okhala ndi magawo atatu. Pamaziko a eccentric iwiri, eccentricity yachitatu ndiyo kuchotsedwa kwa axis poyerekeza ndi pakati pa thupi la valve. Kupanga kwatsopano kumeneku ndi mwayi wapadera kuposa valavu yagulugufe yachikhalidwe.
Ubwino wa triple eccentric butterfly valves
1. Zero kutayikira
Maonekedwe apadera a chinthu chosindikizira cha valve ya butterfly eccentric katatu imathetsa kukangana ndi kuvala, zomwe zimapangitsa kuti valavu ikhale yolimba m'moyo wonse wa valve.
2. Kutentha kwakukulu ndi kukana kwamphamvu
Mavavu agulugufe agulugufe omwe ali ndi zitsulo zitatu zonse komanso valavu yagulugufe yamitundu yambiri yosanjikiza katatu amatha kutentha kwambiri komanso madzi othamanga kwambiri.
3. Kapangidwe kamoto
Zida zonse za katatu eccentric agulugufe valavu amatha kukwaniritsa miyezo yolimba yosayaka moto, ndikupangitsa kuti ikhale yopambana pamapulogalamu osayaka moto.
4. Torque yochepa ndi kukangana
Valavu yagulugufe yamitundu itatu imatha kuchepetsanso torque ndi mikangano, potero imagwira bwino ntchito, kuchepetsa torque ndikukulitsa moyo wautumiki.
5. Ntchito zosiyanasiyana
Valavu ya butterfly ya katatu ndi yoyenera kugwiritsa ntchito zosiyanasiyana, kuphatikizapo mafuta ndi gasi, petrochemical, kupanga magetsi ndi mafakitale oyenga.
Kuipa kwa katatu eccentric agulugufe mavavu
1. Mtengo wapamwamba
Valavu yagulugufe yamagulugufe atatu imakhala ndi mtengo wokwera poyambira chifukwa cha mapangidwe ake apamwamba komanso kapangidwe kake.
2. Kutaya mutu pang'ono
Zowonjezera zowonjezera mu katatu kapangidwe ka eccentric zingapangitse kutayika kwamutu pang'ono kusiyana ndi valavu yawiri eccentric.
Vavu yagulugufe yamtundu wa Double eccentric VS katatu eccentric butterfly valve
1. Mpando wa vavu
Mpando wa valavu wa valavu ya gulugufe wapawiri nthawi zambiri umayikidwa mu groove pa mbale ya valve ndipo umapangidwa ndi mphira monga EPDM, kotero ukhoza kukwaniritsa chisindikizo chopanda mpweya, koma sichiyenera kugwiritsidwa ntchito kutentha kwambiri. Mpando wa valavu wa katatu eccentric agulugufe valavu ndi zonse zitsulo kapena Mipikisano wosanjikiza, choncho ndi oyenera kutentha kwambiri kapena dzimbiri zamadzimadzi.
2. Mtengo
Kaya ndi mtengo wamapangidwe kapena zovuta zopangira, mavavu agulugufe agulugufe atatu ndi apamwamba kuposa ma valve agulugufe opangidwa ndi ma eccentric. Komabe, mafupipafupi a kukonzanso pambuyo pokonza ma valve atatu a eccentric ndi otsika kusiyana ndi ma valve awiri a eccentric.
3. Torque
Cholinga choyambirira cha mapangidwe amtundu wa agulugufe atatu ndikuchepetsanso kutha komanso kukangana. Chifukwa chake, torque ya valavu yagulugufe katatu ndi yaying'ono kuposa ya agulugufe ang'onoang'ono.
