Mavharuvhu ebhorauyebutterfly valves ndiwo mapoka maviri anokosha emavharuvhu uye anoshandiswa zvakanyanya.Ivhavha yebhora inoda kuiswa chisimbiso kwakasimba pakupisa kwepamusoro uye kudzvinyirira kwakanyanya uye kushomeka kwekuyerera.Butterfly mavharuvhu anonyanya kushandiswa kumamiriro ekushanda ane low pressure uye yakaderera chisimbiso zvinodiwa.

 

Kune zvakare akawanda Classifications ebhora mavharuvhu uye butterfly mavharuvhu.Mavharuvhu ebhora anogona kukamurwa kuita: simbi yakaoma-yakavharwa bhora mavharuvhu, yakapfava-yakavharwa bhora mavharuvhu, anoyangarara bhora mavharuvhu, yakatarwa bhora mavharuvhu, eccentric semi-bhora mavharuvhu, V-yakaumbwa inodzora bhora mavharuvhu, nezvimwe.

 

Iyo shavishavi vharafu yakakamurwa kuita: matatu eccentric butterfly vharafu, kaviri eccentric butterfly vharafu, centerline butterfly vharafu, yakaoma sealing butterfly vharafu, yakapfava yekuvharisa butterfly vharafu.

 

Mavharuvhu ebhora uye butterfly mavharuvhu anowanzoshandiswa mavharuvhu.Mune zvimwe zviitiko, zvose zvinogona kushandiswa zvakafanana, uye mune mamwe mamiriro ekushanda, imwe chete inogona kushandiswa.Hunhu hwakasiyana hwemhando mbiri idzi dzemavharuvhu.Isu tinoongorora muchidimbu:

Bhora vharafu: vharafu yejongwe yakashanduka, iyo yekuvhura nekuvhara chikamu idenderedzwa, maitiro ndeaya:

1. Kudzivirira kutenderera kudiki.Kana yavhurwa zvizere, hapana zvikamu zvinovharira kuyerera kwepakati mugero;

2. Inogona kuvharwa zvachose pasi pekumanikidzwa kwepamusoro uye kupisa kwepamusoro;

3. Inogona kuvhurwa nekuvharwa nekukurumidza;

4. Ziva kukwirira kupfeka kusagadzikana uye kuramba kwakasimba kwekuora kuburikidza nekuomesera kurapwa;

5. Muviri wevharuvhu unofananidzwa, unogona kunyatsomira kumanikidzwa kwepombi uye unogona kurarama nepamusoro-soro yekushanda.

 

Butterfly valve: Chikamu chekuvhura nekuvhara idisc type butterfly plate, iyo inoratidzwa ne:

1. Chimiro chakareruka, hukuru hudiki uye kuiswa kwakakodzera;

2. Diki inoyerera inopikisa coefficient, kukurumidza kuvhura nekuvhara;

3. Inogona kushandiswa kune mavharuvhu makuru edhayamita;

4. Zvisimbiso zvakasiyana-siyana zvinogona kushandiswa munzvimbo dzakasiyana-siyana, kusanganisira powdery uye granular media.

 

Kuenzaniswa nevharuvhu yebhora, vhejivhavhavha ine chisimbiso chakashata zvishoma, asi pakati pemavharuvhu makuru-diameter, butterfly valve ine mukana wakasiyana pamusoro pevhavha yebhora;kana inoshandiswa kugadzirisa chiyero chekuyerera, butterfly valve ine chikamu chiduku chekugadzirisa, nepo V-mhando yekugadzirisa bhora revhavha inogadziriswa.Mumapaipi ekudzvanya kwepamusoro, mavharuvhu ebhora ane zvakanakira pane mavharuvhu eshavishavi.
