Mavavu akulu akulu akulu amatanthawuza mavavu agulugufe okhala ndi mainchesi akulu kuposa DN500, omwe nthawi zambiri amalumikizidwa ndi ma flanges, zopyapyala.Pali mitundu iwiri ya mavavu agulugufe okhala ndi m'mimba mwake: mavavu agulugufe okhazikika komanso ma valve agulugufe.
Momwe mungasankhire valavu yayikulu yagulugufe?
1. Pamene kukula kwa valve kuli kochepa kuposa DN1000, kuthamanga kwa ntchito kumakhala pansi pa PN16, ndipo kutentha kwa ntchito kumakhala pansi pa 80 ℃, nthawi zambiri timalimbikitsa valavu ya butterfly ya concentric line chifukwa idzakhala yochuluka kwambiri.
2. Kawirikawiri, pamene m'mimba mwake ndi wamkulu kuposa 1000, timalimbikitsa kugwiritsa ntchito valve butterfly eccentric, kotero kuti torque ya valve ikhoza kuchepetsedwa bwino chifukwa cha eccentric angle ya valve, yomwe imathandizira kutsegula ndi kutseka kwa valve. valavu.Kuphatikiza apo, valavu yagulugufe ya eccentric imatha kuchepetsa kapena kuthetsa kukangana pakati pa mbale ya valve ndi mpando wa valve chifukwa cha mbali ya eccentric, ndikusintha moyo wautumiki wa valve.
3. Panthawi imodzimodziyo, kukhazikitsidwa kwa mipando yachitsulo kumapangitsa kuti kutentha ndi kupanikizika kwa ma valve a butterfly kukhale bwino komanso kumapangitsa kuti mavavu agwiritsidwe ntchito.Chifukwa chake valavu yagulugufe yamitundu yayikulu yapakati nthawi zambiri imatha kugwiritsidwa ntchito pamikhalidwe yotsika ngati madzi, pomwe valavu yagulugufe ya eccentric ingagwiritsidwe ntchito m'malo okhala ndi zovuta zogwirira ntchito.

Kanema Wochokera ku L&T Valves
Komwe valavu ya Big Size Butterfly imagwiritsidwa ntchito
Ma valve agulugufe akuluakulu amagwiritsidwa ntchito m'mafakitale osiyanasiyana omwe amafunikira kuyenda kwakukulu.Zina zomwe zimagwiritsidwa ntchito pamagulu akulu akulu akulu ndi awa:
1. Malo opangira madzi: Mavavu agulugufe amagwiritsidwa ntchito m'malo opangira madzi kuti azitha kuyendetsa madzi kudzera m'mipope yayikulu.
2. Zopangira magetsi: Mavavu a butterfly amagwiritsidwa ntchito m'mafakitale opangira magetsi kuti azitha kuyendetsa madzi kapena nthunzi kudzera m'mipope yomwe imadyetsa ma turbines.
3. Mafakitale opangira mankhwala: Ma valve a butterfly amagwiritsidwa ntchito m'mafakitale opangira mankhwala kuti azitha kuyendetsa mankhwala kudzera mu mapaipi.
4. Makampani amafuta ndi gasi: Mavavu agulugufe amagwiritsidwa ntchito m’makampani amafuta ndi gasi kuwongolera kayendedwe ka mafuta, gasi, ndi madzi ena kudzera m’mapaipi.
5. Makina a HVAC: Mavavu a gulugufe amagwiritsidwa ntchito potenthetsa, mpweya wabwino, ndi mpweya wozizira (HVAC) kuti azitha kuyendetsa mpweya kudzera m'mipata.
6. Makampani opanga zakudya ndi zakumwa: Mavavu agulugufe amagwiritsidwa ntchito m'makampani azakudya ndi zakumwa kuti azitha kuyendetsa bwino madzi ndi mpweya kudzera muzokonza.
Pazonse, ma valve agulugufe akuluakulu amagwiritsidwa ntchito pa ntchito iliyonse yomwe kuthamanga kwakukulu kumayenera kuyendetsedwa ndikuzimitsa mofulumira komanso moyenera.
Ndi ma actuators amtundu wanji omwe amagwiritsidwa ntchito kwambiri popanga ma valve akulu akulu akulu?
1.Worm Gear - Zida za nyongolotsi ndizoyenera mavavu akulu akulu akulu akulu.Ndipo ndi Economical ndi otetezeka kusankha, Sichiyenera kudalira malo malo, malo okwanira ntchito.Bokosi la giya nyongolotsi limatha kukulitsa torque, koma limachepetsa liwiro losinthira.Vavu yagulugufe ya nyongolotsi imatha kudzitsekera yokha ndipo siyingasinthe kuyendetsa.Mwina pali chizindikiro cha udindo.
2.Electric Actuator-Mavavu agulugufe okhala ndi m'mimba mwake amafunikira voteji yanjira imodzi kapena voteji ya magawo atatu pamalopo, nthawi zambiri voteji yanjira imodzi ya 22V, voteji ya magawo atatu a 380V, nthawi zambiri mitundu yodziwika bwino ndi Rotork.Imagwira ntchito pamagetsi a hydropower, zitsulo, ntchito zam'madzi, chakudya ndi mankhwala, ndi zina zimagwira ntchito yayikulu.
3.Hydraulic Actuator-Chingwe chachikulu cha hydraulic butterfly valve chili ndi hydraulic station, zabwino zake ndi zotsika mtengo, zokhazikika komanso zodalirika, ntchito yotetezeka, komanso kuthekera kotsegula ndi kutseka mwachangu.
4.Pneumatic Actuator-Chachikulu Pneumatic butterflyvalavu amasankha atatu eccentric multi-level zitsulo hard seal butterfly valavu, amene ndi mkulu kutentha kugonjetsedwa, kusinthasintha, zosavuta kutsegula ndi kutseka, ndi osindikizidwa.Large-diameter butterfly valve actuator, malinga ndi malo omwe amagwirira ntchito kuti apange chisankho.Kuwongolera kwamadzimadzi nthawi zambiri kumagwiritsidwa ntchito pazomera zonse za hydropower..chomwe chimagwiritsidwa ntchito m'mafakitale azitsulo pamagetsi opangira mapaipi a ng'anjo kuti apewe kutentha kwa mpweya mu chitoliro.
Kugwiritsa ntchito valavu yayikulu ya butterfly
Large-diameter magetsi agulugufe valavu chimagwiritsidwa ntchito mphamvu siteshoni Kutentha dongosolo ndi chothandizira akulimbana chachikulu zimakupiza dongosolo ngalande ndi zitsulo, zitsulo, mankhwala ndi machitidwe mafakitale ena, komanso kuteteza chilengedwe, mankhwala madzi, mkulu-nyamuka nyumba yotunga madzi ndi ngalande payipi. kwa kudula kapena kuwongolera gawo loyenda.
Malinga ndi kusankha zipangizo angagwiritsidwe ntchito zinthu sanali dzimbiri mpweya zitsulo: -29 ℃ ~ 425 ℃ zitsulo zosapanga dzimbiri: -40 ℃ ~ 650 ℃;zogwiritsa ntchito TV mpweya, madzi, zimbudzi, nthunzi, mpweya, mafuta, etc. Magetsi flange mtundu molimba chisindikizo gulugufe valavu wa zitsulo zolimba chisindikizo gulugufe valavu, ntchito zapamwamba Mipikisano mlingo atatu eccentric dongosolo, wapangidwa DZW magetsi actuator Flange ndi zitsulo zolimba chisindikizo gulugufe vavu.Pressure level PN10-25=1.02.5MPa;mtundu: DN50-DN2000mmzakuthupi: WCB kuponyedwa zitsulo mpweya zitsulo;304 chitsulo chosapanga dzimbiri / 316 chitsulo chosapanga dzimbiri / 304L chitsulo chosapanga dzimbiri / 316L chitsulo chosapanga dzimbiri.
Valavu yagulugufe yamagetsi yayikulu yokhala ndi mawonekedwe odalirika osindikizira njira ziwiri, kutayikira kwake ndi ziro;palibe chifukwa chochotsa valavu papaipi kuti musinthe chisindikizo (m'mimba mwake kuposa DN700);mayendedwe odzipangira okha mafuta, palibe jekeseni wamafuta, kukangana kochepa;ofukula, yopingasa mitundu iwiri ya unsembe, malinga ndi zosowa za kotunga;valavu thupi, agulugufe mbale chuma angagwiritsidwe ntchito aloyi kuponyedwa chitsulo, ntchito kwa TV m'nyanja.
