Iyo pneumatic flange mhando yesimbi yakaoma seal butterfly vharafu inoumbwa nekota-stroke pneumatic piston actuator uye matatu-eccentric butterfly valve body. Yakagadzirwa iine matatu-dimensional eccentric musimboti kuti iite kuti nzvimbo yekufamba trajectory yenzvimbo yekuvharisa inakidze, uye hapana kupokana uye hapana kupokana pakati penzvimbo dzekuvharira. Kupindira, pamwe chete nekusarudzwa kwakakodzera kwezvinhu zvekuisa chisimbiso, kunovimbisa kuti kuiswa chisimbiso, kusagadzikana kwekuora, kupikisa kwekushisa kwepamusoro uye kusapfeka kwevhavhavhavhavhavha inovimbika.
The valve stem axis yepneumatic flanged metal hard seal butterfly vharafu inobviswa kubva painana pamusoro pefurafura yeshavishavi uye kubviswa kubva muakisi yevharuvhu muviri passage. Iyo vharuvhu yechigaro inotenderedza axis uye vharafu body passage axis inoumba eccentric angle, nokudaro ichigadzira eccentricity katatu. Kana vharuvhu yeshavishavi yavhurwa kubva pa0°～90°, nzvimbo yekuvharisa yeshavishavi ndiro inopatsanurwa kubva pakavharika pechigaro chevharuvhu panguva yekuvhurwa. Kana yakavharwa pa90 ° ～0 °, iyo conical yekuisa chisimbiso pamusoro pepureti yeshavishavi inobata nekudzvanya chigaro chevharuvhu. Shape chisimbiso. Nokudaro, hapana kukakavara pakati pechigaro chevharuvhu uye chisimbiso chepamusoro peplate ye butterfly, kubvisa mukana wekupfeka uye kubuda.
