Shavishavi rinovhura nekuvhara chidimbu idisc-shaped butterfly plate, iyo inotenderera ichitenderedza akisi yaro mumuviri wevharuvhu, nokudaro kuwana kuvhura nekuvhara kana kugadzirisa kwevharuvhu kunonzi shavishavi vharuvhu. Butterfly mavharuvhu kazhinji asingasviki 90 madhigirii akavhurika uye akavharwa. Mavharuvhu e butterfly nemashavishavi haana simba rekuzvivharira. Kuti uwane ndiro yeshavishavi, worm gear reducer inofanira kuiswa pahunde yevharuvhu. Iko kushandiswa kweworm gear reducer haingoite kuti butterfly plate ive nekuzvivharira kugona, kuita kuti butterfly plate imire pane chero chinzvimbo, asi zvakare inovandudza mashandiro evhavha.
Industrial butterfly mavharuvhu anoratidzirwa nekupisa kwekushisa kwakanyanya, kudzvanywa kwepamusoro, dhayamita hombe, kabhoni simbi muviri uye mhete yesimbi panzvimbo yerabha mhete. Hombe tembiricha yeshavishavi vharafu inosungirirwa nendiro yesimbi, inonyanya kushandiswa kufambisa gasi duct uye pombi yegesi yepakati tembiricha yepakati. Concentric butterfly valve Maumbirwo evharuvhu iri ndeekuti axis yehunde, pakati pefurafura yeshavishavi nepakati pemuviri zvakamira zvakafanana. Iyo yekushandisa modhi ine mabhenefiti eyakapusa chimiro uye nyore kugadzira. Iyo yakajairika rabha yakavharwa butterfly valve ndeyerudzi urwu.
Izvo zvisingabatsiri ndezvokuti butterfly plate uye chigaro chevharuvhu chinogara chiri mumamiriro e extrusion, scratch, kureba kukuru kwekudzivirira uye kukurumidza kupera uye kubvarura. Kuti ugadzirise dambudziko reextrusion pakati pe butterfly plate uye chigaro che concentric butterfly valve, imwe eccentric butterfly valve inogadzirwa. Chimiro chayo chechimiro ndechekuti axis ye stem inotsauka kubva pakati pe butterfly plate, kuitira kuti iyo yakadzika mugumo we butterfly plate haisisiri iyo yepakati yekutenderera, uye yakawandisa extrusion pakati pekumucheto kwezasi kwe butterfly plate uye chigaro chakaderedzwa.
Double eccentric butterfly valve ndiyo inonyanya kushandiswa kaviri eccentric butterfly valve, iyo inowedzerwa kuvandudzwa pahwaro hweimwe eccentric butterfly valve. Chimiro chinoratidza kuti axis yehunde yevharuvhu inotsauka kubva pakati pebhoti re butterfly nepakati pemuviri. Mhedzisiro yekaviri eccentricity inoita kuti butterfly plate ibude kubva pachigaro chevharuvhu pakarepo mushure mekuvhurwa kwevharuvhu, ichibvisa zvakanyanya kuwedzeredza-extrusion uye kukwenya pakati peplate ye butterfly nechigaro chevharuvhu, kuderedza kuvhurika, kuderedza kusakara uye kubvaruka, uye kuvandudza hupenyu hwebasa rechigaro chevhavha.
