Triple Eccentric Butterfly Valve
triple eccentric butterfly valve ke eng?
Boraro eccentric serurubele valve,e tsejoang hape e letriple offset butterfly valve,ke mofuta o mong oa li-valve tsa serurubele tse sebetsang hantle, tse etselitsoeng maemo a ts'ebetso a khatello e phahameng, mocheso o phahameng, le maqhubu a phahameng a ho buleha le ho koaloa.
Li-valve tsa serurubele tse nang le rabara e kholo, tse nang le moralo o holileng le theknoloji ea tlhahiso, li tšepahala ka boleng ebile li mosa ka litšenyehelo. li-valve tsa serurubele se thata, setulo sa tšepe kapa setulo sa ceramic, se etselitsoeng mocheso o phahameng, khatello e phahameng kapa maqhubu a phahameng a ho koala, a ile a qala ho sebelisoa, empa ts'ebetso ea tiiso ea serurubele sa setso se thata e ne e lula e le taba e kholo.
Boraro eccentric serurubele valve(eo hape e tsejoang e le triple offset butterfly valve) e qapiloe tabeng ena.
Ho na le litšobotsi tse ngata bakeng sali-valve tsa serurubele sa eccentric tse tharo.Ho na le setulo sa li-valve se kopantsoeng le 'mele, se nang le li-angles tse ntlafalitsoeng tsa litulo, tse koahetsoeng ka lisebelisoa tse thibelang ho koaheloa tse loketseng limilione tsa ho bula le ho koala, tšepe e sa hloekang e thibelang kutu, le lisebelisoa tsa mocheso o phahameng. lesale la ho tiisa ka thata li behiloe ka har'a diski ea serurubele.Moetso oa mofuta ona o lumella ho etsa hore valve ea serurubele sa eccentric e se ke ea hlola e hanana le litšisinyeho tsa mocheso kapa litlhoro tsa khatello le corrosions, ha e bapisoa le li-valve tsa setso tsa serurubele.

Moralo oa Triple offsets
- Ntho ea pele ea ho fokotsa ke hore sekhahla sa valve se ka morao ho "disk shaft" e le hore tiiso e ka koala ka ho feletseng setulo sohle sa valve.
- Phapang ea bobeli ke hore moeli o bohareng oa shaft ea valve o fokotsehile ho tloha pipe le valve centerline ho qoba tšitiso ea ho bula le ho koala valve.
- Phetoho ea boraro ke hore mokokotlo oa li-cone oa setulo o kheloha bohareng ba shaft ea valve, e leng ho felisang khohlano nakong ea ho koala le ho bula le ho finyella tiiso e tšoanang ea compression ho potoloha setulo sohle.
Ka holimo ke kenyelletso eatriple eccentric butterfly valve.Ke mofuta oa valve ea serurubele e sebetsang hantle haholo e sebelisoang hona joale libakeng tse ngata.
Likarolo tsa mantlha tsa li-valve tsa serurubele sa eccentric tse tharo
- Kaho ea tšepe eohle e sa cheng.
- Stellite® grade 6 setulo se koaheletsoeng se fana ka nako e telele haholo.
- Litšupiso tsa disc tse bulehileng/tse koetsoeng le sesupo sa boemo ba disc sa kantle se nolofatsa lits'ebetso tsa ho kenya / ho tlosa ho API 609.
- selikalikoe sa tiiso ea tšepe e kopaneng e tiisa hore ho ajoa ka matla a litulo ho potoloha selika-likoe sa setulo se entsoeng ka mochini.
- Letheba le shebaneng le flange le tiisa bolting nut le washer planarity, ho eketsa ts'epahalo le polokeho ea manonyeletso.
- Mehele ea tiiso ea graphite e ka nkeloa sebaka habonolo.
- Shaft e matlafalitsoeng haholo e etselitsoeng ho fetisa / ho boloka torque hantle.
- Litšireletso tse nang le graphite tse lohiloeng li thibela ho kenella ha litšila, li netefatsa hore torque e ntse e sebetsa le ho sebetsa ha valve.
- Li-packing gland tse peli le liphutheloana tsa graphite li fokotsa kotsi ea ho tsoa ka ntle.
- Khokahano ea senotlolo e sirelelitsoeng ea shaft-to-disc bakeng sa botšepehi bo phahameng ba shaft.
- Li-gaskets tsa leqeba la Spiral, tiiso le ho paka mehele e ka nkeloang sebaka ntle le lisebelisoa tse khethehileng.
- Li-bearings tse boima li mamella meroalo e phahameng ea khatello le ho senyeha.
- Ho sebetsana le kotsi ea ka hare le ka ntle ea shaft extrusion e lumellana le litekanyetso tsa machaba.
