Flanged butterfly valveskeraklan gagamitan da la keng industrial production pipelines. Ing manimunang obra na yapin ing pututan ne ing dagus ning medium keng pipeline, o kaya i-adjust ne ing daloy ning medium keng pipeline.Flanged butterfly valvesmaralas lang gagamitan kareng pipeline ning produksyun kareng pangkabilugan a industriya antimo reng proyektung pamag-ingat king danum, pamag-treat king danum, petrolyu, industriya ning kemikal, ampong pamag-init king lakanbalen, at malyari la muring gamitan kareng condensers ampong cooling water systems da reng thermal power stations.

Flanged butterfly valvesila reng masanting para gawa kareng maragul a diametru a balbula. Maralas lang magagamit keng larangan ning regulasyun a maragul a diametru. nung ingflanged butterfly valvemebuklat ya, ing resistensya ning danum malati ya. nung ing butterfly plate mibuklat ya keng angle a 15-70° nung ingflanged butterfly valveagyu nang kontrolan ing medium flow a sensitibo.

Dagdag pa, uling ing butterfly plate ningflanged butterfly valveatin yang wiping properties nung mag rotate ya, ining klasing balbula malyari yang gamitan kareng pipeline a ating suspended particle media. Agpang keng sikanan ning seal, malyari ya namang gamitan para keng powder Shaped ampo granular medium pipeline.

Klasipikasyun ningflanged butterfly valves

Flange butterfly valvesmalyari yang pipartian keng malambut a sealflange butterfly valvesat matigas a tatakflange butterfly valvesagpang keng materyales ning sealing surface.

Ing sealing pair ningsoft-sealing flanged butterfly valvegawa ya keng elastic sealing materials antimo ing goma ampo fluoroplastics; ing pamagtatak kareng matibe-tatakflanged butterfly valvegawa ya keng metal-to-metal, metal-to-fluoroplastic ampo multi-layer composite board.

Ing sealing ring ningsoft-sealed flanged butterfly valvemalyari yang i-inlay keng valve body passage, ampo malyari yang i-inlay keng paligid ning butterfly plate. Nung gamitan ya bilang shut-off valve, ing kayang sealing performance miras ya keng FCI70-2:2006 (ASME B16 104) VI Ing level na mas matas ya kesa keng hard-sealed flanged butterfly valve; pero uling ing soft-sealed a materyal limitadu ya keng operating temperature, ing soft-sealed flanged butterfly valve keraklan gagamitan de keng larangan ning pamag-ingat keng danum ampo ing pamag-treat keng danum keng temperatura ning silid.

Ing metal hard sealflange butterfly valveatin yang advantage kareng materyales, malyari yang makibagay keng mas matas a temperatura, mas matas a pressure, ampo mas makaba ya ing service life kesa keng soft seal, pero atin yang disbentaha ing hard sealflange butterfly valvemalino la naman. Masakit yang akwa ing kumpletung pamag-seal, at ing pamag-seal e ya masanting, inya ining uri ning flanged butterfly valve keraklan gagamitan de kareng okasyun a e mangailangan matas a pamag-seal para ma-regulate ing danum.
