Khetho ea li-valve tsa butterfly, tšebeliso e nepahetseng le tataiso ea tlhokomelo

Li-valve tsa serurubele ke lisebelisoa tsa ho laola phallo ea kotara tse sebelisang diski ea tšepe e potolohang ho potoloha axis ea stem e tsitsitseng. Ke li-valve tse laolang phallo tse sebetsang ka potlako tse lumellang likhato tse 90 tsa ho potoloha ho tloha ho bula ka botlalo ho isa boemong bo koetsoeng. Ha disc e le perpendicular ho ea bohareng ba pipe, valve e sebakeng se koetsoeng. mochine oa ho laola (disk) o batla o lekana le bophara bo ka hare ba phala e haufi. Li-valve tsena li tla ka boholo bo fapaneng le meralo e khethollang ts'ebetso ea tsona lits'ebetsong tsa ts'ebetso ea indasteri; lisebelisoa tsa li-valve tsa bohloeki; litšebeletso tsa mollo; mekhoa ea ho futhumatsa, ea ventilation, le air conditioning (HVAC); le li-slurries.Ha re bua ka mokhoa o pharaletseng, li-valve tsa serurubele li bohlokoa bakeng sa taolo ea phallo le ho itšehla thajana. Ho tsamaea ha disc ho qala, ho liehisa kapa ho emisa ho phalla ha metsi e 'ngoe ea litšoaneleho tse latelang tsa phallo: • Hoo e ka bang linear - lebelo la phallo le lekana le ho sisinyeha ha angular ea disc.Ka mohlala, ha disc e bulehile 40%, phallo ke 40% ea boholo.Tlhaloso ena ea phallo e tloaelehile ka holimo. li-valve tsa serurubele tsa ts'ebetso. • Ho bula ka potlako - Tšobotsi ena ea phallo e bontšoa ha ho sebelisoa li-valve tsa serurubele tse lutseng tse tsitsitseng. Lebelo la phallo ea mokelikeli le phahameng ka ho fetisisa ha disc e tloha sebakeng se koetsoeng.Ha valve e atamela sebaka se bulehileng ka ho feletseng, phallo e theoha butle-butle ka phetoho e nyenyane. • Phallo Isolation - Li-valve tsa Butterfly li ka fana ka ts'ebeletso ea mokelikeli oa ho tima / ho tima. Ho itšehla thajana hoa hlokahala neng kapa neng ha karolo e itseng ea tsamaiso ea liphaephe e hloka tlhokomelo. Li-valve tsa butterfly li loketse likopo tse fapaneng ka lebaka la moralo oa tsona o bobebe le ts'ebetso e potlakileng.Li-valve tsa serurubele tse lutseng li loketse mocheso o tlase, lits'ebetso tse tlase tsa khatello, ha li-valve tsa serurubele tse lutseng ka tšepe li na le bokhoni bo botle ba ho tiisa ha li sebetsana le maemo a mokelikeli a thata.Ts'ebetso ena e sebetsa. ka mocheso o phahameng le likhatello 'me e fetisa maro a viscous kapa a senyang.Melemo ea li-valve tsa serurubele e kenyelletsa: • Kaho e bobebe ebile e kopane - Serurubele se sebelisa diski e tšesaane e le mokhoa oa ho laola phallo.Li-disc li nyane ebile li nka sebaka se senyane, empa li matla ka ho lekaneng ho laola ho phalla ha metsi.Li-valve tsena li na le 'mele o momahaneng o etsang hore li tšoanelehe ho sebelisoa tsamaisong ea liphaephe libakeng tse moqotetsane.Liphaephe tse bophara bo boholo li hloka li-valve tse khōloanyane tse sebelisang thepa e ngata ea ho etsa thepa, ho eketsa litšenyehelo.Serurubele se nang le serurubele se tla theko e tlaase. ho feta valve ea bolo ea boholo bo lekanang hobane e sebelisa thepa e nyane ho e etsa. • Ho Tiisa ka Potlako le ka Hantle - Li-valve tsa serurubele li fana ka tiiso e potlakileng ha li sebetsa, e leng se etsang hore e be tse loketseng bakeng sa ho phalla ka mokhoa o nepahetseng haholo. e tla fana ka tiiso e lekaneng bakeng sa lits'ebetso tsa khatello e tlaase - ho fihlela ho lik'hilograma tse 250 ka square inch (psi) .The valve double offset e fana ka tiiso e babatsehang bakeng sa lits'ebetso ho fihlela ho 1,440 psi. Li-valve tsa triple offset li fana ka tiiso bakeng sa lisebelisoa tsa phallo ho feta 1,440 psi. • Ho theoha ha Khatello e tlase le ho Pholisoa ha Khatello e Phahameng - Li-valve tsa serurubele li na le khatello e tlase ea khatello ho sa tsotellehe taba ea hore disc e lula e le teng ka har'a mokelikeli.Ho theoha ha khatello e tlaase ho bohlokoa ho laola litlhoko tsa ho pompa le matla a tsamaiso.Li-valve tsa butterfly li etselitsoe ho lumella mokelikeli ho khutlisa matla kapele ka mor'a hore a tlohe belofo. • Litlhoko tsa tlhokomelo e tlase - Li-valve tsa Butterfly li na le likarolo tse fokolang tsa ka hare. Ha li na lipokotho tse ka tšoarang maro kapa lithōle, ka hona, li hloka ts'ebetso e fokolang ea tlhokomelo. joalo ka ho tjheseletsa ho hlokahala. • Ts'ebetso e Bonolo - Ka lebaka la boholo ba tsona bo kopaneng le boima bo bobebe, li-valve tsa serurubele li hloka torque e batlang e le tlase ho sebetsa. Li-discs tsa tšepe tse tšesaane li sebelisa matla a manyane ho hlola ho hanyetsana ha mokelikeli. fana ka torque e lekaneng bakeng sa ts'ebetso ea bona.Sena se fetolela litšenyehelo tse tlase tsa ts'ebetso - li-activator tse nyane li sebelisa matla a fokolang mme li bitsa chelete e nyane ho eketsa valve. • Li-valve tsa butterfly li ka hlaseloa ke cavitation le phallo e koetsoeng - sebakeng se bulehileng, valve ha e fane ka sekepe se feletseng.Ho ba teng ha disc ka tsela ea phallo ea mokelikeli ho mpefatsa litšila tse pota-potileng valve, ho eketsa monyetla oa ho ba le cavitation.Ball valves. ke mokhoa o mong bakeng sa lits'ebetso tsa mokelikeli tse hlokang likou tse felletseng. • Ho bola ka potlako litšebeletsong tsa mokelikeli oa viscous - maro a ntša li-valve tsa serurubele ha li ntse li phalla. ho hanyetsa ho feta li-valve tsa serurubele. • Ha e tšoanelehe bakeng sa khatello e phahameng ea khatello - valve e lokela ho sebelisoa feela bakeng sa ho ts'oara lits'ebetsong tsa khatello e tlaase, e lekanyelitsoeng ho likhato tse 30 ho isa ho tse 80 tsa ho bula. Sephahla sa valve sebakeng se bulehileng ka ho feletseng se thibela ho hloekisoa ha tsamaiso le ho thibela pigging ea mola o nang le valve ea serurubele. Boemo ba ho kenya valve ea serurubele hangata bo pakeng tsa li-flanges. Li-valve tsa butterfly li lokela ho kenngoa bonyane li-diameter tse 'nè ho isa ho tse tšeletseng tsa liphaephe tse tsoang ho li-nozzles tse ntšang metsi, li-elbows, kapa makala ho fokotsa liphello tsa moferefere.
