Mavharuvhu eshavishavi mahombe anowanzo reva mavharuvhu eshavishavi ane dhayamita rakakura kupfuura DN500, anowanzo batanidzwa neflanges, wafers.Kune marudzi maviri emavharuvhu eshavishavi hombe-dhayamita: vharavhavhavha yeshavishavi uye eccentric butterfly valves.
Iwo matatu eccentricities eTriple Eccentric Butterfly Valve anoreva:
Yekutanga eccentricity: iyo valve shaft iri kuseri kweplate yevharuvhu, ichibvumira chisimbisoRing kunyatsokomberedza chigaro chose mukubata.
Yechipiri eccentricity: iyo spindle inogadziriswa kubva pacenter mutsara wemuviri wevhavha, unodzivirira kupindira nekuvhura uye kuvhara kwevhavha.
Chechitatu eccentricity: chigaro inogadziriswa kubva pakati pemutsara wevhavha shaft, iyo inobvisa kupokana pakati pedisc uye chigaro panguva yekuvhara nekuvhura.
Iyo kaviri eccentric butterfly valve inotumidzwa zita rezvimiro zvaro zviviri eccentric.Saka iyo double eccentric structure yakaita sei?
Iyo inonzi double eccentric, yekutanga eccentric inoreva shaft yevharuvhu iri kubva pakati penzvimbo yakavharwa, zvinoreva kuti dzinde riri kuseri kwechiso chevharuvhu.Eccentricity iyi inoita kuti pakatarisana neplate yevharuvhu uye chigaro chevharuvhu chive chisimbiso, icho chinokunda kusakwana kwemukati kunowanikwa mumavharuvhu e butterfly, zvichibvisa mukana wekupinda mukati mukati mekumusoro nezasi mharadzano pakati pevharuvha shaft uye. chigaro chevharuvhu.
Butterfly valve, iyo inonziwo flap valve, iri nyore chimiro chevharuvhu yekugadzirisa, inogona kushandiswa mumapaipi epasi-pasi kuvhara kuyerera.Kutenderera kutenderedza vharafu shaft kuti uwane kuvhurika nekuvhara vharafu.
Zvinoenderana neakasiyana mafomu ekubatanidza, anogona kukamurwa kuita wafer butterfly vharafu, lug butterfly vharafu, flange butterfly vharafu, welded butterfly valve, screw thread butterfly valve, clamp butterfly valve, zvichingodaro.Pakati peanonyanya kushandiswa mafomu ekubatanidza iwafer butterfly valve uye lug butterfly valve.
Iyo pneumatic butterfly valve inoumbwa nepneumatic actuator uye butterfly valve.Air actuated butterfly valve inoshandisa mweya wakadzvanyirirwa sechitubu chemagetsi kutyaira dzinde revharuvhu uye kutonga kutenderera kwedhisiki kutenderedza shaft kuvhura nekuvhara vharafu.
Maererano pneumatic mudziyo inogona kupatsanurwa mune imwe-kuita pneumatic butterfly vharafu uye kaviri-kuita pneumatic butterfly vharafu.
