Butterfly valve, inonziwo flap valve, ivharuvhu inogadzirisa ine chimiro chakareruka.Butterfly mavharuvhu anogona kushandiswa kushandura kutonga kwepasi-kudzvanywa pombi media.Varuvhu yeshavishavi inoshandisa dhisiki kana kuti butterfly plate sedhisiki, iro rinotenderera nevharuvhu kuvhura nekuvhara.
Butterfly mavharuvhu anogona kushandiswa kudzora kuyerera kwemhando dzakasiyana dzemvura dzakadai semhepo, mvura, chiutsi, akasiyana siyana anoodza media, madhaka, oiri, simbi yemvura uye radioactive media.Iyo inonyanya kutamba basa rekucheka uye kupuruzira pane pombi.Chikamu chekuvhura nekuvhara chevhavhavhavhavhavhavhavhavhavhavharuvhuvhu idhisiki-shape butterfly plate inotenderera ichitenderedza axis yayo mumutumbi wevharuvhu kuti iwane chinangwa chekuvhura nekuvhara kana kugadzirisa.
Izvo zvakakosha zvevhavhavhavhavhavha ndeye: diki yekushandisa torque, diki yekuisa nzvimbo uye huremu huremu.Kutora DN1000 semuenzaniso, iyo butterfly valve inenge 2 T, nepo gedhi regedhi rinenge 3.5 T, uye butterfly valve iri nyore kusanganisa nemhando dzakasiyana dzekutyaira, uye ine kusimba kwakanaka uye kuvimbika.Kuipa kwerubha-yakavharidzirwa butterfly valve ndeyokuti kana ichishandiswa kutinhira, cavitation ichaitika nekuda kwekushandiswa kusina kunaka, izvo zvichaita kuti peeling uye kukuvara kwechigaro cherubha, saka kuti ungasarudza sei zvakarurama zvinoenderana nezvinodiwa zvekushanda. mamiriro.Hukama huri pakati pekuvhurwa kwevharuvhu yeshavishavi uye mwero wekuyerera unochinja zvakanyanya.Kana iyo yakashandiswa kudzora kuyerera, maitiro ayo ekuyerera anoenderanawo zvakanyanya nekuyerera kwekupokana kwepombi.Semuenzaniso, kana mapaipi maviri akaiswa ane dhayamita yevhavha imwechete uye fomu, asi kurasikirwa kwehuwandu hwepombi kwakasiyana, kuyerera kwemavhavha kuchasiyanawo zvakanyanya.Kana vharuvhu iri mumamiriro ekukura kukuru, cavitation inowanzoitika kuseri kweplate yevhavha, iyo inogona kukuvadza valve.Kazhinji, inoshandiswa kunze kwe15 °.Kana vharuvhu yeshavishavi iri pakati pekuvhura, chimiro chekuvhura chinoumbwa nemuviri wevharuvhu uye kumucheto kwemberi kweshavishavi ndiro inonangana nevharuvhu shaft, uye mativi maviri anoumba nyika dzakasiyana.Kunoperera ndiro yeshavishavi kune rimwe divi rinofamba richitevedza nzira inoyerera mvura, uye rimwe divi richienda kudivi remvura inoyerera.Naizvozvo, rimwe divi remuviri wevharuvhu neplate yevharuvhu zvinoumba kuvhurika kwakafanana nemhuno, uye rimwe divi rakafanana nekuvhurwa kwakafanana nekuvhurika.Kuyerera kwevelocity padivi renozzle inokurumidza kupfuura iyo iri padivi re throttle, uye kudzvanywa kwakashata kunogadzirwa pasi pevharuvhu padivi re throttle, kazhinji Chisimbiso cherabha chinobuda.Iyo torque yekushandisa yevhavhavhavhavha inosiyana nekuvhura uye yekuvhura nekuvhara nzira yevharuvhu.Kune mavharuvhu ehorizontal butterfly, kunyanya mavharuvhu makuru-diameter, nekuda kwekudzika kwemvura, torque inogadzirwa nemusiyano pakati pepamusoro nepamusoro misoro yevhavha shaft haigone kuregererwa.Uye zvakare, kana gokora rakaiswa padivi rekupinza revhavha, kuyerera kwe bias kunoumbwa uye torque inowedzera.Kana vharuvhu iri pakati pekuvhura, iyo inoshanda sisitimu inoda kuzvivharira yega nekuda kwekuita kwemvura inoyerera torque.
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.Imwe yeanokurumidza mavharuvhu marudzi.Butterfly mavharuvhu anoshandiswa zvakanyanya.Iyo yakasiyana-siyana uye huwandu hwekushandiswa kwayo ichiri kuwedzera, uye iri kukura yakananga kupisa kwakanyanya, kudzvanywa kwepamusoro, dhayamita hombe, kuiswa chisimbiso, hupenyu hurefu, hunhu hwakanaka hwekugadzirisa, uye kuwanda-kushanda kwevharuvhu.Kuvimbika kwayo uye zvimwe zviratidzo zvekuita zvasvika padanho repamusoro.
Ivharuvhu yeshavishavi kazhinji inenge isingasviki 90° kubva pakazaruka kusvika pakavharwa zvakazara.Ivhavhavhavhavha neshavishavi tsvimbo hazvina kuzvivharira.Kuti ugadzike ndiro ye butterfly, worm gear reducer inofanira kuiswa padanda revhavha.Kushandiswa kwegonye giya rekudzikisira hakungogonese kuti butterfly plate ive nekuzvivharira kugona, inoita kuti butterfly plate imire pane chero chinzvimbo, asi zvakare inovandudza kushanda kwevhavha.Hunhu hweindasitiri yakakosha butterfly vharafu: kupisa kwekushisa kwepamusoro, kukwirira kunoshanda kudzvanywa, hombe dhayamita yevharuvhu, muviri wevharuvhu wakagadzirwa nekabhoni simbi, uye mhete yekuisa chisimbiso yeplate yevharuvhu inogadzirwa nesimbi mhete pachinzvimbo chesimbi. mhete yerabha.Mavharuvhu makuru-akakwirira-kupisa anogadzirwa nesimbi yesimbi uye anonyanya kushandiswa kune flue gasi ducts uye gasi mapaipi epamusoro-tembiricha media.
