Na li-valve tsa serurubele lia fetisoa ka bobeli?

Butterfly Valve ke mofuta oa sesebelisoa sa ho laola phallo se nang le kotara-turn rotational motion , E sebelisoa liphaepheng ho laola kapa ho arola ho phalla ha metsi ( lino tse metsi kapa likhase ) , Leha ho le joalo, Valve ea boleng bo botle le ts'ebetso ea serurubele e tlameha ho hlomelloa ho tiisa hantle. Na li-valve tsa serurubele li fetisetsoa mahlakoreng a mabeli? Ka tloaelo re arola belofo ea serurubele ka li-valve tsa serurubele se Concentric le eccentric butterfly valve .
Re tla tšohla ka bidirectional ea li-valve tsa serurubele ka tsela e latelang:

Serurubele sa Concentric ke eng?

Concentric butterfly valve know as resilient seated or zero-offset butterfly valves , Likarolo tsa tsona li kenyelletsa :Valve body , disc ,seat , stem and seal .sebopeho sa concentric butterfly valve ke disc le setulo se tsamaisana bohareng ba valve , 'me shaft kapa stem e teng bohareng ba disc. Sena se bolela hore disc e potoloha ka har'a setulo se bonolo, Thepa ea setulo e ka kenyelletsa EPDM, NBR Viton Silicon Teflon Hypalon kapa elastomer.

Mokhoa oa ho sebetsa concentric butterfly valve ?

Ho hahoa ha valve ea serurubele ho batla ho le bonolo , ho na le mekhoa e meraro ea actuator bakeng sa ho sebetsa : Lever Handle bakeng sa boholo bo fokolang , Worm Gear box bakeng sa li-valve tse kholo ho etsa hore ho be bonolo ho laola le ho sebetsa ka Automated (ho kenyelletsa Motlakase le Pneumatic Actuators)
Belofo ea serurubele e sebetsa ka ho potoloha disk (kapa vane) ka har'a phala ho laola ho phalla ha mokelikeli. Disk e behiloe holim'a stem e fetang ka 'mele oa valve,' me ho fetola stem ho potoloha disk e ka bula kapa ho koala valve, Ha shaft e ntse e potoloha, disc e fetoha sebaka se bulehileng kapa se bulehileng, se lumella mokelikeli hore o phalle ka bolokolohi.

Na li-valve tsa serurubele li fetisetsoa mahlakoreng a mabeli?

Bidirectional-means e ka laola phallo ka mahlakoreng a mabeli, Joalokaha re buile, molao-motheo oa ho sebetsa oa li-valve o ka finyella litlhoko .Kahoo li-valve tsa serurubele se concentric li bidirectional , Ho na le melemo e mengata ea ho sebelisa serurubele se concentric.
