Amavalve ovemvane angahlukaniswa abe amavalvu ovemvane womoya, amavalvu ovemvane kagesi, amavalve uvemvane, njll. Ivalve uvemvane ivalvu esebenzisa ipuleti lovemvane eliyindilinga njengengxenye yokuvula neyokuvala futhi izungeza nesiqu se-valve ukuvula, ukuvala nokulungisa. i-fluid passage.Ipuleti uvemvane we valve uvemvane ifakwe ohlangothini ububanzi iphayiphi.Endlini eyisilinda yomzimba wevalvu uvemvane, ipuleti uvemvane okumise okwediski lizungeza i-eksisi, futhi i-engeli yokuzungeza iphakathi kuka-0° no-90°.Lapho ukujikeleza kufinyelela ku-90 °, i-valve ivuliwe ngokugcwele.I-Butterfly valve, ebizwa nangokuthi i-flap valve, iwuhlobo lwevalve elawulayo enesakhiwo esilula.Ingase futhi isetshenziselwe ukulawula okuvaliwe kwemidiya yamapayipi anengcindezi ephansi.I-Butterfly valve ibhekisela ohlotsheni lwe-valve ingxenye yalo yokuvala (idiski noma ipuleti levemvane) iyidiski, ezungeza i-valve shaft ukuze ifinyelele ukuvuleka nokuvala.Isetshenziselwa ikakhulukazi ukusika nokudonsa epayipini.I-valve uvemvane evula futhi evala ingxenye iyipuleti uvemvane okumise okwediski, elizungeza i-eksisi yalo emzimbeni wevalvu ukufeza injongo yokuvula nokuvala noma ukulungisa.I-valve uvemvane ivamise ukuba ngaphansi kuka-90° ukusuka ekuvulekeni kuya ekuvalekeni ngokugcwele.I-valve uvemvane kanye nesiqu sovemvane azinawo amandla okuzivala.Ukuze kumiswe ipuleti levemvane, isinciphisi segiya lezikelemu kufanele sifakwe esiqwini sevalvu.Ukusetshenziswa kwe-worm gear reducer akukwazi nje ukwenza ipuleti le-butterfly libe nekhono lokuzivala, lenze ipuleti levemvane lime kunoma iyiphi indawo, kodwa futhi lithuthukise ukusebenza kwe-valve.I-valve ye-butterfly yezimboni ibonakala ngokumelana nokushisa okuphezulu, ububanzi bokucindezela okuphezulu okusebenzayo, ububanzi obukhulu be-valve, umzimba we-valve wenziwe nge-carbon steel, futhi indandatho yokuvala yepuleti ye-valve isebenzisa indandatho yensimbi esikhundleni sendandatho yerabha.I-valve ye-butterfly enkulu yokushisa okuphezulu yenziwe nge-steel plate welding, futhi isetshenziselwa ikakhulukazi amapayipi e-flue namapayipi egesi okushisa okuphezulu kwemidiya.

Ama-valve e-Butterfly angahlukaniswa ngohlobo lwepuleti ye-offset, uhlobo lwepuleti eliqondile, uhlobo lwepuleti ethambekele kanye nohlobo lwe-lever ngokusho kwesakhiwo.Ngokwefomu lokufaka uphawu, lingahlukaniswa ngezinhlobo ezimbili: uhlobo oluvalwe ngokuqhathaniswa nohlobo oluvalwe kanzima.Uhlobo lophawu oluthambile ngokuvamile lusebenzisa indandatho yerabha, futhi uhlobo lophawu oluqinile luvamise ukusebenzisa indandatho yensimbi.Ngokusho kohlobo lokuxhuma, ingahlukaniswa ibe uxhumano lwe-flange nokuxhumeka kwe-wafer;ngokuya ngemodi yokudlulisa, ingahlukaniswa ngemanuwali, ukuhanjiswa kwegiya, i-pneumatic, ihydraulic kanye nogesi.
