I-pneumaticuvemvane valveluhlobo lwe-valve yokulawula esetshenziswa kabanzi kumapayipi ezimboni. Ingxenye yayo eyinhloko iyidiski emise okwediski efakwe epayipini futhi izungezisa ku-eksisi yayo. Lapho i-disc ijikeleza ama-degree angama-90, i-valve ivala; Uma ijikeleziswa ngamadigri angu-0, i-valve iyavuleka.

Umgomo wokusebenza we-pneumatic stainless steel stainless valve valve ukulawula ukujikeleza kwepuleti lovemvane nge-actuator yomoya. I-actuator yomoya ithola umoya ocindezelwe njengomthombo wamandla, futhi ishayela ipuleti levemvane ukuthi livule noma livale ngokuvumelana nezidingo zesignali yokulawula. Le ndlela yokushayela yenza i-valve ye-butterfly ye-pneumatic ibe nezinzuzo zejubane lokuphendula ngokushesha, ukunemba kokulawula okuphezulu, ukusebenza okulula nokunye.

Ama-valve ovemvane womoya asetshenziswa kakhulu emikhakheni yezimboni. Ngokuyinhloko isetshenziselwa ukulungisa izinga lokugeleza nokucindezela kwe-medium, kanye nokufeza ukusika nokuxhuma kwepayipi. Ngenxa yesakhiwo sayo esilula, usayizi omncane nesisindo esilula, i-valve yevemvane ye-pneumatic eccentric inokusebenza okuhle kokugeleza ohlelweni lwamapayipi, okunganciphisa ukumelana noketshezi kanye nokusetshenziswa kwamandla. Ngaphezu kwalokho, i-valve yevemvane engu-4 Intshi yomoya inokumelana nokugqwala okuhle nokumelana nezinga lokushisa eliphezulu, futhi ingakwazi ukuzivumelanisa nezimo ezihlukahlukene ezinokhahlo.

Ama-valve emvemvane we-pneumatic asetshenziswa emikhakheni eminingi yezimboni, njenge-petrochemical, amandla kagesi, i-metallurgy, imithi, ukudla nokunye. Embonini ye-petrochemical, ama-valve emvemvane we-pneumatic avame ukusetshenziswa ohlelweni lwamapayipi kawoyela ongahluziwe, uwoyela ocolisisiwe, izinto zokusetshenziswa zamakhemikhali neminye imidiya. Embonini yamandla, ama-valve emvemvane we-pneumatic asetshenziswa kakhulu emigqeni yokudlulisela amanzi okupholisa, igesi kaphethiloli kanye neminye imithombo yezindaba ezitshalweni zikagesi. Embonini ye-metallurgical, ama-valve butterfly womoya asetshenziswa ezinhlelweni zamapayipi ezinokushisa okuphezulu kwezinsimbi ezincibilikisiwe nezinye imidiya.

Kafushane, i-valve uvemvane womoya idlala indima ebalulekile ohlelweni lwamapayipi ezimboni ngesakhiwo sawo esiyingqayizivele kanye nesimiso sokusebenza. Ayikwazi ukufeza ukulawula okunembile kokugeleza okuphakathi nokucindezela, kodwa futhi inokumelana nokugqwala okuhle nokumelana nokushisa okuphezulu, ngakho-ke isetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni.
