Butterfly valveimhando yevharuvhu inoshandisa dhisiki yekuvhura nekuvhara nhengo kudzoreredza nezve 90 ° kuvhura, kuvhara kana kugadzirisa kuyerera kwepakati.Butterfly valve haina kungoita chimiro chakareruka, hukuru hudiki, huremu huremu, kuderera kwekushandisa, diki yekuisa saizi, diki yekutyaira torque, nyore uye nekukurumidza kushanda, asiwo ine yakanaka yekuyerera mutemo basa uye kuvhara chisimbiso maitiro panguva imwe chete.Ndiyo imwe yemhando dzevharuvhu dziri kukurumidza kukura mumakore gumi apfuura.Butterfly mavharuvhu anoshandiswa zvakanyanya mumaindasitiri mazhinji.Iyo yakasiyana-siyana uye huwandu hwekushandiswa kwayo ichiri kuwedzera, uye iri kusimukira yakananga kukushisa kwepamusoro, kukwirira kwepamusoro, dhayamita yakakura, kuisa chisimbiso chepamusoro, hupenyu hurefu, maitiro ekugadzirisa, uye akawanda-kushanda kwevhavha imwe.Kuvimbika kwayo uye zvimwe zviratidzo zvekuita zvasvika padanho repamusoro.
Nekushandiswa kwekemikari inodzivirira synthetic rabha pavharuvhu yeshavishavi, kushanda kwevhavhavhavhavha yakavandudzwa.Sezvo rabha rekugadzira riine hunhu hwekuramba corrosion, kusakura kwekukurwa, kugadzikana kwedimensional, kusimba, kusimba, kuumba nyore, uye kudhura kwakaderera, rabha rekugadzira rine zvinhu zvakasiyana rinogona kusarudzwa zvichienderana nezvinodiwa zvakasiyana zvekushandisa kusangana nemamiriro ekushanda.butterfly mavharuvhu.
Nekuti polytetrafluoroethylene (PTFE) ine corrosion kusimba yakasimba, kuita kwakagadzikana, kusiri nyore kuchembera, kuderera kwe friction coefficient, nyore kuumba, uye kugadzikana muhukuru, uye hupfumi hwayo hunogona kuvandudzwa nekuzadza nekuwedzera zvinhu zvakakodzera, zvichikonzera kusimba kuri nani uye. kukakavara.Iyo butterfly valve sealing material ine yakaderera coefficient inokunda miganhu ye synthetic rubber, saka zvinhu zvepolymer zvinomiririrwa nePTFE uye kuzadza kwayo uye zvinhu zvakagadziridzwa zvakashandiswa zvakanyanya mumavhavhavhavhavha, kuitira kuti kushanda kwevhavhavhavha inovandudzwa.A butterfly valve ine yakafara tembiricha uye kumanikidzwa siyana, yakavimbika yekuisa chisimbiso kuita uye hupenyu hwesevhisi hurefu hwakagadzirwa.
Kuti usangane nezvinodiwa zvekushandiswa kwekushisa kwepamusoro uye kwakaderera, kukukurwa kwakasimba, hupenyu hurefu uye mamwe maindasitiri ekushandisa,simbi yakanamwa butterfly mavharuvhudzakagadziridzwa zvikuru.Nekushandiswa kwekudzivirira kwekushisa kwepamusoro, kupikisa kwekushisa kwakadzika, kupikisa kwakasimba kwekuora, kusagadzikana kwekukurwa kwevhu, uye simba guru-alloy zvinhu mumavharuvhu emashavishavi, mavharuvhu akavharwa nesimbi ave achishandiswa zvakanyanya muminda yemaindasitiri senge tembiricha yakakwira uye yakaderera, yakasimba. kukukurwa, uye upenyu hurefu.
Kana vharuvhu yeshavishavi yakazarurwa zvizere, ine kushomeka kwekudzivirira kuyerera.Kana kuvhura kunenge kuri pakati pe15 ° ne70 °, kudzora kuyerera kusinganzwisisike kunogona kuitwa, saka mumunda wekugadzirisa dhayamita hombe, kushandiswa kwemavharuvhu e butterfly kwakajairika.
Nekuti kufamba kweshavishavi ndiro kuri kupukuta, mavharuvhu mazhinji eshavishavi anogona kushandiswa kune midhiya ane zvidimbu zvakaturikwa zvakasimba.Zvichienderana nekusimba kwechisimbiso, inogonawo kushandiswa kune yehupfu uye granular media.
Butterfly mavharuvhu akakodzera kuyerera kwemutemo.Nekuti kumanikidzwa kurasikirwa kwevhavhavhavhavha mupombi yakakura, iyo inopeta katatu iyo yevharafu yegedhi, pakusarudza butterfly valve, simba rekumanikidzwa kurasikirwa kwepipeline system inofanira kunyatsotariswa, uye simba repureti ye butterfly kuti rimire kumanikidzika kwepakati pepipeline inofanirawo kufungwa kana yakavharwa.Uye zvakare, iyo yekumisikidza tembiricha yekushanda yeiyo elastomeric chigaro zvinhu pane yakakwirira tembiricha inofanirwawo kutariswa.
Butterfly mavharuvhu ane diki dhizaini kureba uye kureba kwese, kukurumidza kuvhura uye kuvhara kumhanya, uye yakanaka yekudzora hunhu.Chimiro chevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha ndiyo inonyanya kukodzera kugadzira vharafu hombe.Kana iyo butterfly valve inofanirwa kushandiswa pakudzora kuyerera, chinhu chinonyanya kukosha ndechekusarudza zvakatemwa uye mhando yevhavhavhavhavha kuitira kuti ishande nemazvo uye zvinobudirira.
Kazhinji, mukupuruzira, kudzora kudzora uye dhaka svikiro, zvinodikanwa kuve nehurefu hwechimiro chechimiro, kukurumidza kuvhura uye kuvhara kumhanya, kuderera kwekudzvanywa-kubvisa (kusiyana kudiki kwekumanikidza), uye butterfly valve inokurudzirwa.Butterfly valve inogona kushandiswa mukugadzirisa-nzvimbo mbiri, yakaderedzwa dhayamita chiteshi, yakaderera ruzha, cavitation uye vaporization, shoma shoma yekudonha kumhepo, uye abrasive medium.Butterfly valve inogonawo kushandiswa kugadzirisa throttling pasi pemamiriro ekushanda akakosha, kana kushandiswa pasi pemamiriro ekushanda akadai sekusunga chisimbiso, kupfeka kwakanyanya, tembiricha yakaderera (cryogenic), nezvimwe.
