1. Basic a Kabaldugan at Istruktura
Ing soft sealing flanged concentric butterfly valve (ausan da namang "center-line butterfly valve") metung yang quarter-turn rotary valve a dinisenyu para keng on/off o throttling flow control kareng pipelines. Deng kayang core features ilapin deng:
Concentric Design: Ing valve stem, disc, ampo ing luklukan maka-align la keng parehung central axis, gagawang simple ampo compact a istruktura.
Soft Sealing Mechanism: Ing flexible elastomeric seal (alimbawa, goma, EPDM, NBR) makayabe ya keng valve body o luklukan, mamye yang masipit a seal para aiwasan ing leakage.
Flanged Ends: Ing valve atin yang flanged connections, para mas madali yang i-install kareng pipelines a makayagpang kareng standards antimo ing ANSI, DIN, o JIS.
2.Deng susi a sangkap
3. Prinsipyu ning Pamagobra
Makabuklat a Posisyun: Ing disc mag-rotate yang 90° para makalinya ya keng direksyun ning danum, mabawas ing pressure drop ampo paintulutan ing ganap a danum.
Saradu a Posisyun: Ing disc mibalikid ya pabalik para i-press ya ing malambut a seal, gagawang masipit a pamagsara. Ing concentric a disenyu magdependi ya keng elastic deformation ning seal para akwa ing seal, gagawan neng epektibo para kareng low-pressure a aplikasyun.
4. Key Features and Advantages
Masipit a Pamag-seal: Deng malambut a seal mamye lang masanting a leak resistance, maralas makatupad la kareng bubble-tight standards (eg, ANSI B16.104 Class VI, ISO 15848-1).
Low Torque Operation: Ing concentric a disenyu ampo ing flexible seal babawasan na ing friction, para mas mayan ing manual a operasyun o gamitan kareng lightweight actuators.
Compact at Magaan: Nung ikumpara la kareng gate o globe valves, deng concentric butterfly valves mas malati la ampo mas mayan lang i-install keng limitadu a espasyu.
Cost-Effective: Ing simpleng istruktura ampo ing mababang pamangamit materyales gagawan na lang affordable para kareng basic flow control needs.
Versatile Media Compatibility: Suit para keng danum, angin, oil, non-corrosive liquids, ampo granular media (a maki abrasion-resistant coatings).
5. Technical Specifications
Pressure Rating: Keraklan mababa anggang katamtaman a pressure (alimbawa, PN6–PN16 / Class 125–Klasi 150).
Temperature Range:
Standard elastomers (eg, NR, EPDM): -10°C anggang 90°C (14°F anggang 194°F).

6. Aplikasyon
Soft sealing flanged concentric butterfly valves D341X-16Qmaralas lang gagamitan keng:
Supply ning Danum ampo Drainage: Sistema ning danum ning balen, planta ning pamaglinis keng alkantarilya, ampo network ning patubig.
HVAC Systems: Kontrol ning angin, danum, o singaw keng pamangisnawa, pamangisnawa, ampo pamangisnawa.
Industriya ning Pamangan at Inuman: Sanitary applications a maki FDA-compliant seals (alimbawa, EPDM a maki food-grade coatings).
Pangkabilugan a Prosesu ning Industriya: E makasira a pamangamit king likidu kareng tanaman a kemikal, papel, ampong parmasyutika (para mu kareng mild media).
Marine ampo Shipbuilding: On/off control keng dayatmalat o ballast systems (a maki materyales a e maka-corrosion).
7. Limitasyun at Konsiderasyon
Pressure and Temperature Limits: E ya ustung para keng high-pressure (alimbawa, >PN16) o sobrang temperatura (alimbawa, steam babo ning 150°C).
Peligro ning Corrosion: Deng metal a sangkap (alimbawa, cast iron bodies) malyari lang mangalating kareng agresibong kapaligiran; mag upgrade keng stainless steel o coated materials para keng masikan a kundisyun.
Abrasive Media: Deng malambut a seal mabilis lang masira kareng particulate-laden a likidu; isipan mu ing hard-seal butterfly valves o karagdagang proteksiun a coatings.
Pamili ning Actuator: Para kareng maragul a diametru a balbula o maralas a operasyun, gamitan me ing pneumatic/hydraulic actuators para aiwasan ing kapagalan.
8. Install at Maintenance
Pamag-install:
Siguraduan mung maka-align la reng flanges ampo deng bolts maka-tighten lang parehu para aiwasan ing leakage.
Iwasan ing pamag install keng valve keng sobrang pipeline stress.
Ayusan:
Regular meng inspeksyunan ing seal para keng wear o cracking, lalu na keng high-cycle a aplikasyun.
Lubricate me ing stem ampo ing actuator pana-panaun para siguraduan ing masaleseng operasyun.
palitan me ing seal nung atin yang leakage; deng mapilan a disenyu paintulutan da ing pamagpalit seal a alang pamaglako keng balbula keng pipeline.
9. Supplier ampo Product Selection Tips
Material Certification: Siguradwan na ing seals makatupad ya kareng standards ning industriya (alimbawa, FDA para keng pamangan, ATEX para keng explosive a kapaligiran).
Customization Options: Deng mapilan a supplier mag offer lang anti-static designs, fire-safe features, o special coatings (alimbawa, epoxy, PTFE) para kareng niche applications.
Katuntunan
Soft sealing flanged concentric butterfly valvesmetung lang epektibo, mapanalig a solusyun para keng mababang-anggang-katamtaman a pressure flow control kareng e kritikal a aplikasyun. Ing karelang simplisidad, masipit a pamag-seal, ampo ing karelang ease ning pamag-maintain gagawan na lang popular a pilinan keng danum, HVAC, ampo kareng pangkabilugan a sistemang pang-industriya. Para kareng mas demanding a kapaligiran, mas masanting ing pamag upgrade kareng eccentric a disenyu o premium a materyales. Parati meng evaluate ing media properties, operating conditions, ampo reng compliance requirements para mamili kang masanting a valve para kareng kekang kailangan.
