Ma Vavu Agulugufe Awiri Omwe Amakhala Pawiri
Mawonekedwe
▪ Kukwaniritsa kapena kupitilira zofunikira za EN593.Mtundu wa Double Eccentric.
▪ Torque yaing'ono, yosinthasintha komanso yosavuta kugwiritsa ntchito, yopulumutsa antchito komanso yopulumutsa mphamvu.
▪ Mapangidwe apadera, kulemera kwake, kutsegula ndi kutseka mofulumira.
▪ Zida zosindikizira ndizokalamba komanso kukana dzimbiri, ndipo zimakhala ndi moyo wautali wautumiki.
▪ Ikhoza kuikidwa mu positini iliyonse komanso yosavuta kukonza.
▪ Mphete ya Rubber Seat imangiriridwa pa diski ya valve kapena thupi kuti musankhe.
▪ Chida chopatsira nyongolotsi chimakhala chotsekedwa mokwanira ndipo chimatha kugwiritsidwa ntchito m'madzi kwa nthawi yayitali.
▪ Gawo losindikizira losinthika, kusindikiza kodalirika komanso kusatayikira kwa njira ziwiri zosindikizira.
▪ Mounting Flange mogwirizana ndi ISO 5211.
▪ Face to Face Dimension ikugwirizana ndi EN558 Series 13 kapena Series 14.
▪ Kuthamanga kwa mayeso:
Kupanikizika kwa Shell Test 1.5 x PN
Kuthamanga kwa Chisindikizo 1.1 x PN
Mapangidwe a Diski Owongolera
Timagwiritsa ntchito ukadaulo wotsogola kwambiri wothandizidwa ndi makompyuta kupanga ma disc a valve kukhala mawonekedwe ozungulira.Mawonekedwe a mawonekedwe a mafunde amapereka kukhazikika kwamadzimadzi odutsa, kuchepetsa kutayika kwa kuthamanga ndikulola kuyika bwino kwa cavitation.
Zofunikira Zakuthupi

Kupaka
▪ Chovala Chokhazikika cha Epoxy
▪ Chophimba Chapadera Choteteza Ku dzimbiri
Kuphimba kwapadera kumapereka chitetezo chodalirika cha valavu, makamaka pazovuta zina zogwirira ntchito, monga asidi kapena alkali media, madzi okhala ndi matope, dongosolo lozizira, machitidwe a hydropower, madzi a m'nyanja, madzi amchere ndi madzi owonongeka a mafakitale.
EPC (Ceramic ndi Epoxy Two-Comonent Coating)
Kupaka Rubber Wolimba Kapena Wofewa
Polyurethane Painting Mkati ndi Kunja
Kutsekera Kwapadera Kwapadera Kupewa Moto
Kuyitanitsa Zambiri
▪ Mitundu yodziwika bwino komanso yosaphulika pali ma valve agulugufe okhala ndi mphira omwe amakhala ndi makina opangira magetsi.
▪ Chonde tchulani ngati mavavu agulugufe oyendetsedwa ndi nyongolotsi akufunika panjira ziwiri.
▪ Zina zofunika zilipo, chonde fotokozani.
Mfundo Yogwira Ntchito
▪ Vavu ya agulugufe osindikizira njira ziwiri amatsika mphamvu kudzera pa giya ya nyongolotsi ndi njira zina potembenuza gudumu la m'manja kapena lalikulu la chogwirira chake, ndikuyendetsa shaft ya agulugufe ndi gulugufe kuti azizungulira mkati mwa digirii 90 kudzera pakutsika kwa nyongolotsi. , kuti akwaniritse cholinga chodula, kulumikiza kapena kuwongolera kuyenda.Valavu yagulugufe yosindikizira yamagetsi imachepetsedwa ndi chowotcha chamagetsi kudzera mu giya ya nyongolotsi kapena kuyendetsa mwachindunji shaft ya valve ndi diski ya butterfly kuti izungulira mkati mwa digiri ya 90, kuti akwaniritse cholinga cha valve yotseguka ndi kutseka.
▪ Ziribe kanthu kuti ndi zida za nyongolotsi kapena njira yoyendetsera magetsi, kutsegulira kapena kutseka kwa valve kumakhala kochepa ndi malire.Ndipo njira yowonetsera imawonetsa mawonekedwe otseguka a chimbale cha butterfly.
Kugwiritsa ntchito
▪ Ma valve a butterfly amagwiritsidwa ntchito kwambiri pamayendedwe operekera madzi a tauni, makina oziziritsa madzi, kugawa madzi, hydropower system, malo opangira zimbudzi, projekiti yosinthira madzi, makampani opanga mankhwala, kusungunula ndi njira zina zoperekera madzi & ngalande ndi njira zopangira magetsi.Imagwiritsidwa ntchito pamadzi osaphika, madzi oyera, gasi wowononga, sing'anga yamadzimadzi ndi ma multiphase fluid, ndipo imakhala ndi malamulo, odula kapena osabwerera.
▪ Vavu yagulugufe yokhala ndi mipangidwe iwiri yotchinga imagwira ntchito posindikiza njira imodzi.Nthawi zambiri, imayikidwa munjira yolembedwa.Ngati kusindikiza kuli ndi njira ziwiri, chonde zisonyezeni mu mgwirizano wa dongosolo, kapena gwiritsani ntchito mzere wapakati wa gulugufe.
Zolemba
▪ Mapangidwe, zida ndi mafotokozedwe omwe akuwonetsedwa amatha kusintha popanda chidziwitso chifukwa chakukula kosalekeza kwa zinthuzo.
