The centerline butterfly valve ine chimiro chakareruka uye chiri nyore kugadzira, asi nekuda kwechimiro chayo uye miganhu yezvinhu, mamiriro ekushandisa ane mashoma.Kuti zvizadzise zvinodiwa nemamiriro chaiwo ekushandisa, kuvandudzwa kunoenderera kwave kuchiitwa pahwaro uhwu, uyezve eccentric butterfly mavharuvhu, maviri eccentric butterfly mavharuvhu, uye katatu eccentric butterfly mavharuvhu akaonekwa.Chinhu chikuru cheiyi eccentricity yechitatu ndechekuti inoshandura chimiro chekuisa chisimbiso.Haisisiri chisimbiso chechisimbiso, asi chisimbiso che torsion, ndiko kuti, hachivimbi ne-elastic deformation yechigaro chevharuvhu, asi zvachose zvinoenderana nekubatana kwepamusoro kudzvinyirira kwechigaro chevhavha.Iyo yekuisa chisimbiso, saka, inogadzirisa dambudziko re zero kuvuza kwechigaro chesimbi valve mune imwe yakadonha, uye nekuti iyo yekubata kumeso kudzvinyirirwa inoenderana nepakati kudzvanywa, iyo yakanyanya kudzvanywa uye yakakwirira tembiricha kuramba inogadziriswa zvakare nyore.

Zvakanakira katatu eccentric dhizaini

1. Iyo yakasarudzika conical seal dhizaini inovimbisa kuti dhisiki haibati chisimbiso chepamusoro kusvikira valve yakavharwa-izvi zvinotungamirira kuchisimbiso chinodzokororwa uye chinowedzera zvakanyanya hupenyu hwebasa revhavha.

2. Chimiro cheplate yevhavha yekatatu eccentric butterfly valve is elliptical cone, uye pamusoro payo yakashongedzwa neyakaoma alloy, iyo ine yakanakisa kupfeka kusagadzikana.Iyo inoyangarara yeU-yakaita Stainless simbi chigaro chine basa rekugadzirisa otomatiki pakati.Kana vharuvhu yakavhurwa, elliptical cone sealing surface valve disc inotanga kuparadzaniswa kubva kune U-shaped elastic valve seat, uye inotenderera;kana yakavharwa, dhisiki yevhavha inotenderera, uye dhidhi yevhavha inogadzirisa pakarepo pakati pechigaro chevhavha ye elastic pasi pechiito che eccentric shaft.Chigaro chinoshandisa dzvinyiriro yekukanganisa chigaro chevharuvhu kusvika chigaro chevharuvhu uye elliptical conical sealing pamusoro pevhavha disc zvakanyatsoenderana.Kana vharuvhu yakavhurwa uye yakavharwa, butterfly disc haikwenye chigaro chevharuvhu, uye torque yehunde yevharuvhu inotumirwa zvakananga kunzvimbo yekuvharira kuburikidza neplate ye butterfly, uye torque yekuvhura idiki, zvichibva zvabvisa chiitiko chinowanzoitika. pakuvhura vharuvhu.

3. Metal-to-metal sealing inova nechokwadi chekuti mabhuru emhepo akavharwa zvakasimba kuti awane zero leakage performance.

4. Inokodzera hutsinye midhiya-iyo-yose-simbi chimiro inopa ngura uye kupisa kusagadzikana izvo mamwe madhizaini evharuvhu ane elastic seals haana.

5. Iyo geometric dhizaini yezvikamu zvekuisa chisimbiso inogona kupa frictionless kufamba mukati mevhavha.Izvi zvinowedzera hupenyu hwevhavha uye inobvumira kuiswa kwepasi torque actuators.

6. Hapana mhango pakati pezvikamu zvekuvhara, izvo zvisingazokonzeri kuvhara, kuderedza mari yekugadzirisa uye kuwedzera hupenyu hwevhavha.

7. Magadzirirwo echigaro chevhavha anogona kudzivirira vharafu kubva pakuwedzeredza
