LNG Cryogenic butterfly valve yokhala ndi doko lokonzekera

Ndi chidwi chachikulu choperekedwa ndi anthu ku kuipitsidwa kwa chilengedwe m'zaka zaposachedwa, mayiko komanso dziko lapansi akuyesetsa kukhala ndi mphamvu zoyera kuti pang'onopang'ono m'malo mwa magwero amphamvu achikhalidwe ndi kuipitsidwa kwakukulu Makamaka gasi wachilengedwe, monga gwero lamphamvu loyera, limakondedwa kwambiri, ngakhale kukula koopsa kwachitika. Ndi chitukuko chake, ma valve a cryogenic, monga makiyi owongolera ndi magawo odulidwa, apereka zofunikira zatsopano kwa izo.
Pachifukwachi, ife aJUDU tidazindikira izi koyambirira kwa 2008 ndipo tapanga LNG cryogenic butterfly valves (m'mimba mwake mwadzina 8 "-42", kuthamanga msinkhu 150LB-300LB) kwa makampani angapo apakhomo ndi akunja.

Flange kugwirizana kapangidwe cryogenic butterfly valve

Zomwe zimagwiritsidwa ntchito flange yolumikizidwa ndi cryogenic butterfly valve kamangidwe ku China amasinthidwa kutengera ochiritsira ochiritsira atatu eccentric gulugufe valavu. Pali zigawo ziwiri zazikulu zotengedwa. Choyamba ndikusunga mawonekedwe amkati osasinthika ndikukulitsa bulaketi. Choyipa cha kapangidwe kameneka ndikuti mawonekedwe osindikizira mpando wa valavu sangathe kusinthasintha bwino ndi ma deformations ang'onoang'ono pansi pazikhalidwe za cryogenic, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa kusindikiza kogwira mtima; Njira yachiwiri, monga momwe ikusonyezera pa chithunzi chakumanja, imaphatikizapo kusintha mpando wa valve kuti ukhale wosunthika ndikugwiritsa ntchito mbale zoyikirapo, mawotchi othamanga pampando wa valve, etc. Mapangidwe achiwiri amawongolera mawonekedwe a mpando wa vavu, kupangitsa kuti ikhale yosunthika ndikulipiritsa vuto lotayikira lomwe limayambitsidwa ndi mapindikidwe pansi pa kusintha kwa kutentha; Choyipa: Sichigwiritsa ntchito kukonza pa intaneti. Pamene ma valve mkati ayenera kusinthidwa mwachizolowezi, valve iyenera kupasuka ndi kusinthidwa poyamba.

Mbali yokhala ndi valavu ya butterfly ya cryogenic yokhala ndi doko lokonzekera

Kapangidwe kam'mbali kokhala ndi doko lokonza, zomwe sizimangotsimikizira kusindikizidwa kodalirika ngakhale m'malo ovuta kwambiri a -196 ℃, komanso kutha kuwongolera ndikusintha zida zamkati pa intaneti. Pamaziko a dongosolo lapitalo, dzenje limatsegulidwa pambali, ndipo mbale ya butterfly ndi zigawo zosindikizira zimayikidwa kudzera pa doko lokonzekera. Vavu ikafunika kukonzedwa, tsegulani chivundikiro chokonzekera kuti mulowe mkati ndikulowetsamo zigawo zamkati.

Zomwe zili m'mbali mwa mawonekedwe agulugufe wa cryogenic wokhala ndi doko lokonzekera

Kapangidwe ka katatu ka offset

1st offset: Axial eccentricity, malo osindikizira amayikidwa mbali imodzi ya tsinde la valavu, ndipo malo osindikizira ndi eccentric ku tsinde la valve.
2nd offset: Radial eccentricity, pakati pa tsinde la valavu imapatuka pakatikati pa payipi, ndipo tsinde la valavu limakhala lapakati pa tchanelo.
3rd offset: Pamwamba pa cone ndi eccentric, ndipo kuzungulira kwa mphete yosindikizira ya elliptical kumakulitsidwa kuti apange kondomu yokhazikika, yomwe ili ndi nsonga ya cone yokhazikika pakati pa njira.

atanyamula

Kulongedzaku kumatengera kulongedza kwa EagleBurgmann othawa kwawo, ndipo mphete yake yomaliza imalukidwa ndi kaboni fiber ndi graphite yokulitsidwa. M'mphepete mwa mphete yomaliza imakhala ndi mphete ya graphite yochuluka kwambiri, ndipo pakati ndi kapu yokhala ndi kachulukidwe kakang'ono kamene kamakulitsidwa ndi mphete ya graphite, yomwe imakumana ndi TA luft, ISO15848, API622, AP1589 ndi mfundo zina.

Chivundikiro cha Valve Chachitali cha Neck ndi bolodi lodontha    

Kutengera kapangidwe ka chivundikiro cha khosi lalitali la valavu, malo a bokosi lolongedza amakwezedwa kuti athe kulongedza kuti azigwira ntchito pamalo opitilira 0 ℃. Kuphatikiza kuwerengera kwamalingaliro, kusanthula kwazinthu zomaliza, ndi zoyeserera, kutalika kwa chivundikiro cha vavu ndi makulidwe a khoma kumatsimikiziridwa kuti achepetse kutentha kwambiri momwe angathere.
Mapangidwe a drip board amachepetsa kufalikira kwa kutentha kwa thupi kupita kumalo onyamula ndi kumtunda kwa valavu, kuonetsetsa kuti kutentha kwapang'onopang'ono ndi kumtunda kwa tsinde la valve kuli pamwamba pa 0 ℃. Drip board imateteza bwino mpweya wamadzi wotentha kwambiri kuti usagwere pamaboti a flange ndikupangitsa dzimbiri.

mphete yosindikiza yoyandama

Mphete yosindikiza yoyandama imagwiritsidwa ntchito, yomwe imatha kusintha malo ake pathupi la valavu molingana ndi kukankhira pomwe mbale ya valve yatsekedwa. Chisindikizo choyandamachi chikhoza kubweza zinthu monga mapindikidwe ndi kufalikira kwa matenthedwe a valavu ya thupi pansi pa kutentha kochepa, kuthetsa kuwonongeka kwa malo osindikizira, kuonetsetsa kuti yunifolomu yosindikizira ikugwira ntchito, kuwonjezera moyo wautumiki wa chisindikizo, ndikuwongolera kusindikiza kwachitsulo chosindikizira cholimba. Kapangidwe kameneka kamathetsa vuto la kutsekeka kwamadzi chifukwa cha kusintha kwa kutentha.

Kukonza Port

Kugwiritsa ntchito valavu yokhala ndi doko lokonzekera kumathandizira kuti ma valve otenthetsera azitha kukonzedwa popanda kufunikira kochotsa valavu yonse, mbale yagulugufe, tsinde la valavu, ndi zolumikizira zina zogwirizana ndi payipi yamadzimadzi. Mapangidwe osindikizira otsekeka amapangitsa kukonza ndikusinthanso zosindikiza kukhala zosavuta komanso zogwira mtima. Chophimba cha valve chokhala ndi mphete zonyamulira kuti chiwunikidwe chimapangitsa kukonza kukhala kosavuta.

Kapangidwe kameneka kakukonza kwatsopano pa intaneti valavu ya butterfly sangangosintha kuchuluka kwa zomwe zilipo mavavu agulugufe pa mapaipi a LNG, komanso azilimbikitsidwa kwambiri ndikugwiritsidwa ntchito m'malo ena komwe kuli kovutirapo kutulutsa mavavu pamapaipi akulu ofanana. M'malo mwake, m'mapaipi opangira zinthu zosiyanasiyana monga mafuta a petrochemicals ku China, pali malo ambiri komwe ntchito singayimitsidwe maola 24 patsiku, kapena kuyimitsidwa kwakanthawi pakukonza mwadzidzidzi. Panthawiyi, ngati valavu yathyoledwa ndipo kukonzanso pang'ono kukuchitika, nthawi ndi yaitali, mphamvu yake ndi yochepa, ndipo mtengo wake ndi wokwera kwambiri, makamaka m'malo ovuta a kugwetsa ndi kukweza mapaipi akuluakulu. Kapangidwe kameneka kamapewa bwino mavutowa, kupulumutsa kwambiri nthawi komanso kuchepetsa ndalama.
