Bangaki Abaphendukayo Ukuvala Ivaluvu Yevemvane

I-valve ye-butterfly eyenziwe ngesandla

Amavalvu amaningi ovemvane okwenziwa ngesandla avaliwe ngokuzungezisa isibambo noma isiqu, futhi ngokuvamile adinga ukuphenduka oku-2 ukuya ku-3 ukuze avale ngokugcwele. Isimiso siwukushintsha isimo sobubanzi ngokuzungezisa ipuleti lovemvane cishe ngo-90° (okungukuthi, ukujika kwekota), kodwa ngenxa yokwakheka kwesakhiwo sokudlulisa (njengegiya lezikelemu), ukusebenza kwangempela kudinga ukuphenduka okuningi.

Ukuzungezisa isibambo ngokwewashi isiqondiso sokuvala, futhi ukuzungezisa okuphambene newashi kuyisiqondiso sokuvula.

Bamba i-butterfly valve: I-valve uvemvane ivulwa futhi ivalwe ngokuphendula isibambo. Kukhona i-disc enamazinyo phakathi kwesibambo nomzimba we-valve, futhi ububanzi bokunyakaza kwesibambo ku-disc enamazinyo buphakathi kuka-0~90 °. Uma isibambo sisendaweni eqondile nepayipi, i-valve ivaliwe; lapho isibambo sihambisana nepayipi, i-valve ivuliwe.

I-Worm gear butterfly valve: Ukuvuleka nokuvalwa kwevalve uvemvane kulawulwa ngokuphendula isondo lesandla ekhanda legiya lezikelemu. Ukuzungezisa isondo lesandla ukuya kwewashi kungavala ivalve yovemvane, futhi ukuyizungezisa ngokuphambene newashi kungayivula.

 

Ama-valve ovemvane akhethekile noma amakhulu

 

Zimbalwa kakhulu izimo ezikhethekile (njengamavalvu embonini amakhulu noma amasistimu okudlulisa ayinkimbinkimbi) angase adinge izinkulungwane zemijikelezo yokusebenza. Isibonelo, imiphumela yosesho iveze ukuthi i-valve idinga ukuzungeziswa izikhathi ezingu-8,000, kodwa izimo ezinjalo ngokuvamile azihlobene namavalve ovemvane, futhi kungenzeka zihilele ukudizayina kokudizayina kwamavalvu esango noma ezinye izinhlobo zamavalvu.

 

I-valve butterfly kagesi

Uma kusetshenziswa i-actuator kagesi, isivinini sokuvala sincike ejubaneni lemoto (ngokuvamile i-12~48 rpm, imiklamo ekhethekile ingafinyelela ngaphezu kuka-100 rpm) 8. Kodwa-ke, le parameter ithinta kuphela isikhathi sokuvala futhi ayihlanganise lutho nenani lokujikeleza kokusebenza okwenziwa ngesandla.

 

I-valve uvemvane womoya

Ngokuvamile kuthatha amajika angama-200 kuye kwangama-600 ukuvala ivalve uvemvane. Ukucaciswa kokusebenza kwe-pneumatic-cut-cut-chetterfly valves kubonisa ukuthi inani lokuvula nokuvala ukujika akufanele libe liningi kakhulu, futhi ama-valve angama-diameter amakhulu kufanele futhi aqedele imisebenzi yokuvula nokuvala phakathi nokujika kwe-200-600.
