Kaviri eccentric butterfly valve ndeyekuti tsinde yevharuvhu inotsauka kubva pakati pefurafura yefurafura nepakati pemuviri. Pahwaro hwehuviri eccentricity, chisimbiso peya yekatatu eccentric butterfly valve inoshandurwa kuita inclined cone.

Kuenzanisa kwechimiro:

Ose maviri eccentric butterfly valve uye katatu eccentric butterfly valve anogona kuita kuti butterfly plate ikurumidze kusiya chigaro chevharuvhu mushure mekuvhurwa, kubvisa zvakanyanya kusingakodzeri kuwedzeredza uye kukwesha pakati pepureti ye butterfly nechigaro chevharuvhu, kuderedza kuvhurika kwekupokana, kuderedza kupera uye kupera simba. kunatsiridza hupenyu hwebasa rechigaro chevhavha.

Kuenzanisa kwezvinhu:

Iwo makuru ekumanikidza zvikamu zvekaviri eccentric butterfly valve akagadzirwa ne ductile iron, uye makuru ekumanikidza zvikamu zveeccentric butterfly valve akagadzirwa nesimbi yekukanda. Simba re ductile iron uye simbi yekukanda inofananidzwa. Ductile iron ine goho repamusoro simba, ine goho rakaderera re310mpa, ukuwo simba regoho resimbi yakakandwa ingori 230MPa. Mumasevhisi mazhinji emanisipala, senge mvura, mvura yemunyu, chiutsi, nezvimwewo, kupikisa kwecorrosion uye oxidation resistance ye ductile iron zviri nani pane zvesimbi yakakandwa. Nekuda kwe spheroidal graphite microstructure ye ductile iron, ductile iron iri nani pane yakakandwa simbi mukudzikisa kuzunguzika, saka zvinonyanya kubatsira kuderedza kushushikana.

Kuenzanisa kwekuisa chisimbiso:

Iyo kaviri eccentric butterfly valve inotora spherical uye inoyangarara elastic chigaro. Pasi pekumanikidzwa kwakanaka, kucheneswa kunokonzerwa nekushivirira kwekugadzira uye kushanduka kwevharuvhu shaft uye butterfly plate pasi pekumanikidzwa kwepakati kunoita kuti spherical surface ye butterfly plate inyatsoenderana pamusoro pekuvhara pamusoro pechigaro chevharuvhu. Pasi pekumanikidzwa kwakashata, chigaro chinoyangarara chinoenda chakananga kumanikidziro epakati pasi pekumanikidzwa kwepakati, Zvinobudirira kubhadhara kubviswa kunokonzerwa nekugadzirisa kushivirira uye deformation yevharuvhu shaft uye butterfly plate pasi pekuita kwepakati pekumanikidzwa, kuitira kuti uone kuvharwa kwechisimbiso.

Iwo matatu eccentric hard sealing butterfly valve anotora yakagadzika yakarerekera conical valve chigaro uye akawanda-level yekuisa chisimbiso mhete. Pasi pekumanikidzwa kwakanaka, kucheneswa kunokonzerwa nekushivirira kwemuchina uye kushanduka kwevhavha shaft uye butterfly plate pasi pekumanikidzwa kwepakati kunoita kuti mhete yekuisa chisimbiso yakawanda-level inyatsoenderana pachisimbiso chechigaro chevharuvhu, asi pasi pekumanikidzwa kunopesana, iyo yakawanda-level sealing. mhete ichave iri kure nechisimbiso pamusoro pechigaro chevharuvhu, Saka, reverse sealing haigone kuwanikwa.
