Lero, ama eccentric butterfly mavavuya fakitale yathu DN1000 ndi DN1200 zapakidwa ndipo zakonzeka kutumizidwa. Gulu ili la mavavu agulugufe lidzatumizidwa ku Russia.

Mavavu agulugufe omwe ali ndi ma eccentric ndi ma valve agulugufe wamba ndi mitundu yodziwika bwino ya ma valve, ndipo amasiyana pamapangidwe ndi magwiridwe antchito. Double eccentric butterfly valve ndi mtundu wochita bwino kwambirivalavu ya butterfly, ndi bwino pamaziko a single eccentric gulugufe valavu, ndi wamba gulugufe valavu zambiri amatanthauza pakati mzere zofewa chisindikizo gulugufe valavu.

Kapangidwe ka double eccentricmtengo valavu butterflyimadziwika ndi tsinde lake lomwe limapatuka kuchokera pakati pa gulugufe mbale komanso kuchokera pakati pa thupi. Kapangidwe kameneka kamapangitsa kuti valavu ikatsegulidwe, chimbalecho chikhoza kuchotsedwa mwachangu pampando, ndikuchotsa kutulutsa kosafunikira kopitilira muyeso ndi kukanda chodabwitsa pakati pa chimbale ndi mpando, potero kuchepetsa kukangana ndi kuvala, ndikuwongolera magwiridwe antchito ndi moyo wautumiki wa valavu.

Kapangidwe ka valavu yagulugufe wamba ndi yosavuta, tsinde lagulugufe, mbale yagulugufe ndi thupi zimakhala zofanana, ndipo zisindikizo zofewa zimagwiritsidwa ntchito, monga mphira kapena polytetrafluoroethylene ndi zipangizo zina, zomwe zimayenera kugwiritsidwa ntchito mu kutentha kwabwino komanso malo otsika kwambiri komanso kukhala ndi ntchito yabwino yosindikiza.

Valavu yagulugufe yamitundu iwiri imagwira ntchito mofanana ndi valavu yagulugufe imodzi yokha, koma chifukwa cha mapangidwe apakati, imakhala ndi ntchito yosindikiza bwino komanso kugundana kochepa komanso kuvala. Mfundo ntchito wamba actuated valavu gulugufe ndi kulamulira otaya madzimadzi ndi kasinthasintha mbale valavu, ndi kasinthasintha mayendedwe a mbale valavu zimatsimikizira otaya madzimadzi. Chifukwa cha mawonekedwe ake osavuta, panthawi yotsegulira ndi kutseka kwa valve ya butterfly ya 6 inchi, mbale ya butterfly ndi mpando nthawi zonse zimakhala zopopera komanso zowonongeka, zomwe zingayambitse kukangana kwakukulu ndi kuvala.

Double eccentric gulugufe valavu ndi oyenera zomera madzi, zomera mphamvu, zitsulo smelting, makampani mankhwala, gwero la madzi zomangamanga, malo zomanga ndi ngalande dongosolo ngalande, makamaka oyenera ntchito payipi madzi monga lamulo ndi kutseka zida.
