Kukanganisa kwerubha seal butterfly valve ndeyokuti kana ichishandiswa kutinhira, cavitation ichaitika nekuda kwekushandiswa kusina kunaka, zvichiita kuti chigaro cherubha chibvise uye kukuvara.Nechikonzero ichi, simbi-yakavharwa butterfly mavharuvhu akagadzirwa pasi rese, uye iyo cavitation zone yakaderedzwa.Mumakore achangopfuura, nyika yangu yakagadzirawo mavharuvhu akavharwa nesimbi.MuJapan, mavharuvhu akaita semashavishavi ane cavitation kuramba, kudedera kwakaderera uye ruzha rwakadzika zvakare akagadzirwa mumakore achangopfuura.
Kazhinji, hupenyu hwechigaro chevhavhavhavhavhavhavha yevharuvhu 15-20 makore erabha uye 80-90 makore esimbi pasi pemamiriro ezvinhu.Zvisinei, kusarudzwa kwakarurama kunoenderana nezvinodiwa nemamiriro ekushanda.
Hukama huri pakati pedhigirii rekuvhura resimbi yekuvharisa shavishavi vharuvhu uye mwero wekuyerera unochinja zvakanyanya.Kana iyo yakashandiswa kudzora kuyerera, maitiro ayo ekuyerera anowiriranawo zvakanyanya nekuyerera kwekupokana kwepombi.Semuenzaniso, mapaipi maviri akaiswa neakaenzana dhayamita yevharuvhu uye fomu, asi pombi kurasikirwa coefficient yakasiyana, uye kuyerera kwevhavha kuchave kwakasiyana kwazvo.Kana iyo valve iri muhurumende ine throttle yakakura, kumashure kweplate yevhavha inotarisana ne cavitation, iyo inogona kukuvadza valve.Kazhinji, inoshandiswa kunze kwe15 °.
Kana simbi yechisimbiso butterfly inogadziriswa iri pakati pekuvhura, iyo yekuvhura chimiro inoumbwa nevharuvhu muviri uye kumucheto kwemberi kweshavishavi ndiro iri pakati pevharuvhu shaft, uye mativi maviri anoumbwa kuti apedze nyika dzakasiyana.Kunoperera ndiro yeshavishavi kune rimwe divi kunofamba kwakananga kumvura inoyerera, uye rimwe divi kunoyerera neshure.Naizvozvo, rimwe divi remuviri wevharuvhu neplate yevharuvhu inoumba kuvhurika-kunge kuvhurika, uye rumwe rutivi rwakafanana nekuvhurika kwemhepo.Rutivi rwenozzle rune kukurumidza kuyerera kupfuura throttle side, uye throttle side valve inoburitsa yakaipa Kudzvanya, zvisimbiso zverabha zvinowanzodonha.
Iyo inoshanda torque yesimbi seal butterfly gadziriso ine hunhu hwakasiyana nekuda kwekusiyana kwekuvhura uye kuvhara nzira dzevhavha.Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhangana,nekuda kwekudzika kwemvura, torque inogadzirwa nemusiyano pakati pemisoro yemvura yepamusoro neyepasi yevhavhavhavhavha 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.

Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
