1.Centerline Butterfly Valve
a.Zvakanakira: Chimiro chakareruka uye chiri nyore kugadzira, chehupfumi;
b.Kukanganisa: Iyo butterfly plate uye chigaro chevhavha chinogara chiri mumamiriro e extrusion uye scraping, kureba kureba kwakakura uye kupfeka kunokurumidza.
c.Zvishandiso: Inoshandiswa zvakanyanya muminda yakawanda senge peturu, makemikari, simbi, uye hydropower.
2.Eccentric Butterfly Valve
a.Zvakanakira: Mira yakakwirira tembiricha uye kumanikidza, Wedzera hupenyu hwechigaro chevharuvhu
b.Zvakaipa: Zvinodhura uye zvakanyanya kuoma kugadzira
c.Zvishandiso: Inoshandiswa zvakanyanya mumvura yepombi pombi yemvura uye dhizaini, suweji, kuvaka, peturu, makemikari, machira akareruka, kugadzira mapepa, simba remvura, simbi, simba, uye mamwe mapurojekiti.
Ngationgororei misimboti yakakodzera uye nhoroondo yekusimudzira yeCentreline butterfly valve uye eccentric butterfly valve mune zvakadzama.
The centerline Butterfly Valve inoratidzwa nepakati peiyo stem axis, pakati pefurafura yefurafura, uye pakati pemuviri munzvimbo imwechete, seyakajairwa centreline valve.Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharu tembiricha-tembiricha uye yakaderera-pressure valve.Iyo ductile iron butterfly valve ndeimwe yemavharuvhu e butterfly

Kune eccentric butterfly valve, iwo marudzi matatu
a.Single Eccentric Butterfly Valve
b.Kaviri eccentric butterfly valve
Nhoroondo ye eccentric butterfly valve type
Iyo imwe eccentric butterfly vharafu imhando yeshavishavi vharafu inogadzirwa kugadzirisa dambudziko rekudzvanya ndiro yeshavishavi uye chigaro chevharuvhu mumutsara wepakati butterfly vharafu.Iyo tsinde axis inotsauka kubva pakati pevhavhavhavhavha kuitira kuti kumucheto kwezasi kwevharuvhu yeshavishavi kusisave axis yekutenderera, iyo inoparadzira uye inoderedza kuchinjika kudzvinya kwekumusoro uye kuzasi migumo yeshavishavi ndiro uye chigaro chevharuvhu.
The double offset butterfly valve imwe yemhando dzevharuvhu yeshavishavi, the stem axis iri kure nepakati pefurafura yefurafura nepakati pemuviri.Mhedzisiro yekaviri eccentricity inoita kuti butterfly plate ikurumidze kubva pachigaro mushure mekuvhurwa kwevhavha, iyo inobatsira kubvisa kudzvinyirira zvakanyanya uye kukwesha pakati pepureti yeshavi uye chigaro uye inovandudza hupenyu hwechigaro.Kunyanya kuderedzwa kwekukwenya kunoita kuti zvikwanise kushandisa zvigaro zvesimbi kune kaviri eccentric butterfly valves, iyo inogona kushandiswa mukupisa kwakanyanya.
The triple eccentric butterfly valve imhando yeshavivhavha, yehunde axis chinzvimbo kutsauka panguva imwe chete, zvichiita kuti conical axis ye butterfly plate sealing surface itsauka kubva pacylindrical axis yemuviri, chisimbiso chepamusoro pefurafura ine elliptical, chimiro chenzvimbo yekuisa chisimbiso saka asymmetric, rumwe rutivi rwakarerekera kumuviri wepakati, rumwe rutivi rwakafanana nemuviri wepakati.Matatu eccentric butterfly mavharuvhu anosandura nzvimbo yekuisa chisimbiso, isisiri chinzvimbo chekuisa chisimbiso, asi chisimbiso che torsion, ichitsamira pane inobatwa pamusoro pechigaro chevharuvhu kuti iite chisimbiso, kugadzirisa dambudziko re zero kuvuza kwechigaro chesimbi valve.Sezvo kubatwa kwepamusoro kudzvinyirirwa uye kumanikidzwa kwepakati zvakaenzana, inogadzirisawo dambudziko repamusoro uye kupisa kwepamusoro, uye butterfly valve inoshandiswa zvakanyanya.
