makananu la gagawan deng butterfly valves?

Balbula ning parulmetung yang uri ning valve na gagamit disc opening ampo closing part para mag reciprocate mga 90° para makabuklat, makasara o maka adjust keng flow rate ning medium. Ing butterfly valve ali yamu simple ing istruktura, malati ya sukad, magaan ya timbang, mababa ing pamangailangan na keng materyales, malati ya ing sukad ning pamag-install, malati ya ing torque ning pamagmaneho, simple ya at mabilis ing operasyun na, nune atin ya namang masanting a flow regulation function ampo closing sealing characteristics, at metung ya kareng pekamasikan a daragul a uri ning balbula keng milabas a apulung banua. Deng butterfly valves maralas lang gagamitan. Ing miyayaliwang uri at dagul ning pamangamit na patuloy yang lalawak, at daragul ya angga king matas a temperatura, matas a presyur, maragul a diametru, matas a kasiksikan, makabang bie, masanting a regulasyun a katangian, at multi-function ning metung a balbula. Ing kayang kapanaligan ampo reng aliwang indicator ning performance miras nala keng matas a antas.

keng pamangamit keng chemically resistant synthetic rubber parabalbula ning parul, ing pamagganap ningbalbula ning parulme-improve ya. Uling ing synthetic rubber atin yang katangian ning corrosion resistance, erosion resistance, dimensional stability, masanting a resilience, madaling maporma, mababang presyu, atbp., ing synthetic rubber a maki miyayaliwang katangian malyari yang mapili agpang kareng miyayaliwang pamangailangan king pamangamit bang akit ing kundisyun ning obra ningbalbula ning parul.

Uling ing polytetrafluoroethylene (PTFE) atin yang masikan a resistensya keng corrosion, matatag a performance, ali ya madaling luma, mababa ing coefficient ning friction, madaling gawan, dimensional stability, ampo malyari yang isundu ing kayang komprehensibung katangian kapamilatan ning pamagpuno ampo pamagdagdag kareng ustung materyales, ing butterfly valve sealing material a mas masanting a sikanan ampo mas mababang coefficient ning friction malyari yang mika limitasyun ing synthetic rubber melampasan ya, inya ing polymer polymeric material a pekakatawan ning PTFE ampo ing kayang filling modified material maralas yang megamit keng butterfly valve, inya ing performance ning butterfly valve lalu yang mipabuti.Balbula da reng parulmas malawak a temperatura ampo pressure, mapanalig a pamag-seal ampo mas makabang bie ning serbisyu ing megawa.

Para akit la reng requirements da reng industrial applications antimo ing matas ampo mababang temperatura, masikan a erosion, ampo makabang bie, deng metal seal butterfly valves me-develop la. Uling king pamangamit king matas a temperatura a resistensya, mababang temperatura a resistensya, masikan a resistensya king kaagnasan, masikan a resistensya king erosion, at matas a sikanan a alloy a materyales kareng butterfly valves, deng metal sealed butterfly valves maralas lang megamit kareng industrial a larangan antimo ing matas ampong mababang temperatura, masikan a erosion, at makabang bie, ampo reng butterfly valves a maki maragul a diametru (~7050), matas a presyur (~ 200 MP). at malawak a temperatura (-196~606°C) ing linwal, inya pin ing teknolohiya da reng butterfly valves miras na king bayung antas.

Nung ing butterfly valve lubus yang makabuklat, atin yang malating flow resistance. Nung ing pasbul atyu ya pilatan ning 15°~70°, malyari yang gamitan para keng sensitive flow control, inya ing pamangamit keng butterfly valve maralas ya keng field ning large-diameter adjustment.

Uling keng wipeable a kimut ning butterfly valve butterfly plate, keraklan kareng butterfly valves malyari lang gamitan para keng media a maki suspended a solidu. Depende keng sikanan ning seal, malyari ya namang gamitan para keng pulbura ampo granular a media.

Deng butterfly valves masanting la para keng pamag-regulate ning danum. Uling ing pressure loss ning butterfly valve keng pipe medyu maragul ya, mga atlung besis kesa keng gate valve, nung mamili kang butterfly valve, ing impluwensya ning pressure loss ning sistema ning pipeline dapat yang lubus a ikonsidera, ampo ing sikanan ning butterfly plate para magdala keng pressure ning pipeline medium nung makasara ya dapat ya namang ikonsidera. Dagdag pa, kailangan mu namang ikonsidera ing limitasyun ning operating temperature nung nukarin ing elastomeric seat material malyari yang i-subject keng matas a temperatura.

Ing butterfly valve atin yang malating kaba ampo katas, mabilis ing pamagbukas ampo pamagsara, ampo masanting a fluid control characteristics. Ing structural principle da reng butterfly valves ing peka masanting para keng pamaglalang kareng large-bore valves. Nung kailangan ing butterfly valve para makontrol ing flow rate, importanti ing mamili kang ustung sukad ampo uri ning butterfly valve para magobra yang masalese ampo epektibo.

Keraklan, keng throttling, regulation control ampo mud medium, ing kaba ning istruktura makuyad ya, ing bilis ning pamagbukas ampo pamagsara mabilis ya, ampo ing mababang pressure cut-off (malating pamiyaliwa ning pressure) kailangan ya, ampo ing butterfly valve ing rekomendadu. Deng butterfly valves malyari lang gamitan nung atin yang adwang posisyun a pamag-adjust, metung a mababang diametru a channel, mababang ingay, cavitation ampo vaporization, ditak a leakage keng atmosphere, ampo abrasive media. keng lalam ning espesyal a kundisyun ning obra, pamag-adjust keng throttling, o mahigpit a pamag-seal, grabing pangasira, mababang temperatura (cryogenic) ampo aliwa pang kundisyun ning obra.
