Zingaki Izindlela Zokuvala I-Butterfly Valve

I-valve yebhabhathane elenziwe ngesandla

Ama-valve amaningi e-butterfly asetshenziswa ngesandla avaliwe ngokujikeleza isibambo noma isiqu, futhi ngokuvamile adinga ukujika okubili kuya kokuthathu ukuze kuvalwe ngokuphelele. Umgomo uwukushintsha isimo sobubanzi ngokujikeleza ipuleti le-butterfly cishe ngo-90° (okungukuthi, ukujika kwekota), kodwa ngenxa yokwakheka kwesakhiwo sokudlulisa (njengegiya le-worm), ukusebenza kwangempela kudinga ukujika okuningana.

Ukujikeleza kwesibambo ngokwewashi kuyindlela yokuvala, kanti ukujikeleza okuphikisana newashi kuyindlela yokuvula.

I-valve ye-butterfly yokubamba: I-valve yebhabhathane iyavulwa futhi ivalwe ngokuphendula isibambo. Kukhona idiski enamazinyo phakathi kwesibambo nomzimba we-valve, futhi ububanzi bokunyakaza kwesibambo ku-diski enamazinyo buphakathi kuka-0 ~ 90°. Uma isibambo sisesimweni esiqondile nepayipi, i-valve iyavalwa; uma isibambo sihambisana nepayipi, i-valve iyavulwa.

I-valve ye-butterfly gear ye-worm: Ukuvulwa nokuvalwa kwevalvu yebhabhathane kulawulwa ngokuphendula isondo lesandla ekhanda legiya le-worm. Ukujikeleza isondo lesandla ngokwewashi kungavala ivalvu yebhabhathane, futhi ukuyizungeza ngokwewashi kungayivula.

 

Amavalvu ebhabhathane akhethekile noma amakhulu

 

Zimbalwa kakhulu izimo ezikhethekile (njengezivikelo ezinkulu zezimboni noma izinhlelo zokudlulisa eziyinkimbinkimbi) ezingadinga izinkulungwane zokujika kokusebenza. Isibonelo, imiphumela yokusesha iveze ukuthi izivikelo zidinga ukujikeleziswa izikhathi ezingu-8,000, kodwa izimo ezinjalo ngokuvamile azihlobene namazivikelo ezimvemvane, futhi cishe zihilela ukungalingani komklamo wamazivikelo ezisango noma ezinye izinhlobo zamazivikelo.

 

I-valve yebhabhathane kagesi

Uma kusetshenziswa i-actuator kagesi, isivinini sokuvala sincike esivinini semoto (ngokuvamile singu-12 ~ 48 rpm, imiklamo ekhethekile ingafinyelela ngaphezu kuka-100 rpm)‌8. Kodwa-ke, le pharamitha ithinta kuphela isikhathi sokuvala futhi ayinalutho oluphathelene nenani lokujikeleza kokusebenza ngesandla.

 

I-valve yebhabhathane yomoya

Ngokuvamile kuthatha ukujika okungu-200 kuya ku-600 ukuvala ivalvu yebhabhathane. Imininingwane yokusebenza kwamavalvu ebhabhathane anqunywa ngokushesha asebenzisa umoya ikhomba ukuthi inani lokujika nokuvula akufanele libe liningi kakhulu, futhi amavalvu amakhulu kufanele futhi aqedele imisebenzi yokuvula nokuvala ngaphakathi kokujika okungu-200-600.
