Butterfly valve imhando yevharuvhu inoshandisa disc mhando yekuvhura nekuvhara zvikamu kufuratira nekudzoka kumashure anenge 90 ° kuvhura, kuvhara kana kugadzirisa mafambiro epakati.Butterfly valve haina kungoita chimiro chakareruka, hukuru hudiki, huremu huremu, kuderera kwekushandisa, diki yekuisa saizi, diki yekutyaira torque, nyore uye nekukurumidza kushanda, asi zvakare ine yakanaka yekuyerera mutemo basa uye kuvhara uye kuisa chisimbiso maitiro panguva imwe chete.Butterfly mavharuvhu anoshandiswa zvakanyanya.
Nekuiswa kwekemikari inodzivirira synthetic rabha pamavharuvhu eshavishavi, kushanda kwemavharuvhu eshavishavi kwakavandudzwa.Sezvo rabha rekugadzira riine hunhu hwekuramba corrosion, kusakura kwekukukurwa, saizi yakagadzikana, kugadzikana kwakanaka, kuumba nyore, uye kudhura kwakaderera, rabha rekugadzira rine zvinhu zvakasiyana rinogona kusarudzwa zvinoenderana nezvinodiwa zvakasiyana zvemashandisirwo kusangana nemamiriro ekushanda evhavhavhavhavha.
Nekuti polytetrafluoroethylene (PTFE) ine corrosion resistance yakasimba, kuita kwakadzikama, kusiri nyore kuchembera, kuderera kwe friction coefficient, nyore kuumba, kugadzikana ukuru, uye kuita kwayo kwakazara kunogona kuvandudzwa nekuzadza nekuwedzera zvinhu zvakakodzera kuti uwane simba riri nani uye kukweshana.Butterfly valve sealing materials ine yakaderera coefficient inokunda miganhu yesynthetic rubber.Naizvozvo, yakakwirira molecular polymer zvinhu zvinomiririrwa ne polytetrafluoroethylene uye kuzadza kwavo kwakagadziridzwa zvinhu zvakashandiswa zvakanyanya mumavharuvhu e butterfly, kuitira kuti kushanda kwemavharuvhu e butterfly kuve nani.Yakave yakagadziridzwa zvakare, uye vharuvhu yeshavishavi ine tembiricha yakafara uye kudzvanywa kwemhando, yakavimbika yekuisa chisimbiso uye hupenyu hwesevhisi hurefu hwakagadzirwa.
Kuti zvizadzise zvinodikanwa zvekushandiswa kwemaindasitiri senge tembiricha yakakwira uye yakaderera, kukukurwa kwakasimba, uye hupenyu hurefu, simbi-yakavharwa butterfly mavharuvhu akagadzirwa zvakanyanya.Nekushandiswa kwekudzivirira kwekushisa kwepamusoro, kupikisa kwekushisa kwakadzika, kupikisa kwakasimba kwekuora, kupikisa kwakasimba kwekukurwa kwevhu, uye simba guru-alloy zvinhu mumavharuvhu e butterfly, mavharuvhu akavharidzirwa nesimbi ave achishandiswa zvakanyanya muminda yemaindasitiri senge tembiricha yakakwira uye yakaderera, yakasimba. kukukurwa, uye upenyu hurefu.Butterfly mavharuvhu ane dhayamita hombe (9 ~ 750 mm), high pressure (42.0 MPa), uye yakakura tembiricha siyana (-196 - 606 ° C) akaonekwa.
Kana vharuvhu yeshavishavi yakazarurwa zvizere, ine diki yekuyerera inopikisa.Kana kuvhura kunenge kuri pakati pe15 ° ~ 70 °, inogonawo kuita seti yekudzora kuyerera, saka mumunda wekutonga-dhayamita hombe, kushandiswa kwemavharuvhu e butterfly kwakajairika.
Sezvo kufamba kweshavishavi ndiro kuchipukuta, mavharuvhu mazhinji eshavishavi anogona kushandiswa kune midhiya ane akaturikwa akasimba zvidimbu.Zvichienderana nekusimba kwechisimbiso, inogonawo kushandiswa kune powdery uye granular media.
Butterfly mavharuvhu akakodzera kuyerera kwemutemo.Sezvo kupera simba kwevhavhavhavha yeshavishavi mupombi yakakura, inopeta katatu iyo yevharuvhu yegedhi, pakusarudza vharuvhu yeshavishavi, pesvedzero yekurasikirwa kwekumanikidzwa kwepombi system inofanirwa kutariswa zvizere, uye kusimba kweiyo butterfly plate yekumira nepressure ye pipeline medium kana yakavharwa inofanirwa kutariswawo..Uye zvakare, kudzikisira kwekushisa kwekushanda kweiyo elastic chigaro zvinhu pakupisa kwakanyanya kunofanirwawo kutariswa.
Kureba kwechimiro uye kureba kwese kwevhavhavhavhavha idiki, kuvhura nekuvhara kumhanya kunokurumidza, uye ine yakanaka yekudzora hunhu.Nheyo yemaitiro evhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha ndiyo inonyanya kukodzera kugadzira mavharuvhu makuru.Kana iyo butterfly valve inofanirwa kushandiswa pakudzora kuyerera, chinhu chinonyanya kukosha ndechekusarudza zvakatemwa uye mhando yevhavhavhavhavha kuitira kuti ishande nemazvo uye zvinobudirira.
Kazhinji, mavharuvhu eshavishavi anokurudzirwa kupuruzira, kudzora kudzora uye madhaka media uko kupfupi kwechimiro kureba, kukurumidza kuvhura uye kuvhara kukurumidza, uye kuderera kwekudzvanywa-kubvisa (kuderera kudiki mutsauko) kunodiwa.Butterfly mavharuvhu anogona kusarudzirwa kaviri-chinzvimbo kugadzirisa, kuderedzwa-dhayamita chiteshi, yakaderera ruzha, cavitation uye vaporization, shoma shoma yekudonha kumhepo, uye abrasive media.Kugadziriswa kweThrottle pasi pemamiriro ekushanda anokosha, kana mamiriro ekushanda anoda kuiswa chisimbiso chakasimba, kupfeka kwakanyanya, kupisa kwakadzika (cryogenic) nezvimwe zvakadaro.
