Damper butterfly valve kana yatinodaidza kuti Ventilation butterfly valve inonyanya kushandiswa muair conditioning system yeindasitiri blast furnace gasi rekugadzira magetsi, metallurgy uye migodhi, kugadzira simbi, yepakati imhepo kana flue gasi.Nzvimbo yekushandiswa iri pamugero mukuru weiyo ventilation system kana chiutsi exhaust system, saka saizi yevharuvhu kazhinji ichave yakakura.

Basa guru re damper nderokugadzirisa chiyero chekuyerera, zvinodiwa zvechisimbiso hazvisi zvakakwirira, uye imwe chiyero chekudonha inobvumirwa.Kazhinji, simba rekunze rinodiwa kutyaira, semagetsi kana pneumatic nzira.

Mamiriro evharuvhu ari nyore, uye anongova necenterline butterfly plate uye dzinde revharuvhu.Nokuda mukaha mukuru pakati shavishavi ndiro uye vharafu muviri, pane zvakakwana kuwedzera nzvimbo, saka anogona zvinobudirira kudzivirira thermal kuwedzera uye contraction kunokonzerwa tembiricha kuchinja panguva kushandiswa, uye ikoko hakuzoitike dhisiki akanamatira mamiriro .

Kubatsira kweiyo Damper chimiro:

• Pachave pasina kupokana kana uchichinja, hupenyu hwesevhisi hwakareba zvakanyanya,
• Uye kushorwa kwayo kuyerera kudiki, kutenderera kwakakura, uye hakuzokonzerwi nekuwedzera tembiricha
• kureruka, nyore, nekukurumidza actuated
