Vhiki yapfuura, fekitari yakapedza basa rekugadzira bhechi resimbibutterfly valve. Zvinhu zvacho zvakanga zvakaumbwa nesimbi, uye vharafu imwe neimwe yakanga ine mudziyo wevhiri remaoko, sezvinoratidzwa mumufananidzo unotevera.

Thematatu eccentric butterfly valveinowana chisimbiso chinoshanda kuburikidza nechimiro chakasiyana. Kana nzvimbo yekutenderera yeplate yevharuvhu (kureva, nzvimbo yeshaft) inotsauka kubva pakati pemuviri wevharuvhu, inoumba yekutanga eccentricity. Mutsara wepakati pechisimbiso chepamusoro peplate yevharuvhu inotsauka kubva pakati pemuviri wevharuvhu, ichigadzira yechipiri eccentricity. Chisimbiso pamusoro pechigaro chevharuvhu chakagadzirwa mune conical chimiro, kuitira kuti chisimbiso pamusoro peplate yevharuvhu uye chisimbiso chepamusoro pechigaro chevhavha chiumbe imwe Angle. Iyi ndiyo yechitatu eccentricity.

Paunenge uchivhura vharafu, ndiro yevharuvhu, pasi pechiito chemudziyo wekutyaira, chokutanga chinobvisa kubva pachisimbiso chechigaro chevhavha uye yozotenderera kuderedza kukweshera. Kana yakavharwa, mushure mokunge chivharo chevhavha chichitenderera panzvimbo, pasi pekumanikidzwa kwepakati kana simba remudziyo wekufambisa, inonyatsoomerera kune chisimbiso chechigaro chechigaro chevhavha, ichivhara kuyerera kwepakati. Iyi matatu-eccentric dhizaini inovimbisa kuti panguva yekuvhura nekuvhara nzira yevhavha, panenge pasina kupokana pakati peplate yevharuvhu uye chigaro chevhavha chisimbiso chepamusoro, nekudaro kuwedzera hupenyu hwebasa. Zvichakadaro, inogona kuwana bidirectional pressure kuramba uye ine yakanaka yekuisa chisimbiso kuita.

Mamiriro ezvinhu umo china katatu eccentric butterfly mavharuvhu anoshandiswa zvakanyanya:

1. Petrochemical field: Muzvikamu zvinoputika zvinoputika zvemafuta ekugadzirisa mafuta, inoshandiswa kudzora kutonhora kwepamusoro-kupisa, high-pressure mafuta uye gasi media ine tsvina yakasvibiswa kuti ive nechokwadi chekushanda kwakagadzikana kwechikwata; Mukugadzira kemikari, kana uchitakura zvakanyanya corrosive acid uye alkali mhinduro, yakakosha yekuisa chisimbiso chimiro chinogona kudzivirira nepakati kuvuza uye kuve nechokwadi chekuchengetedzwa kwekugadzirwa.

2. Indasitiri yemagetsi: Mupombi yepombi yemagetsi emagetsi ekupisa, katatu eccentric manual butterfly valve (worm gear butterfly valve) inogona kuenderana nemamiriro ekushanda ekugara achivhura uye kuvhara kwemhepo inopisa uye kunyatsogadzirisa kuyerera kwemhepo. Mune inotonhorera sisitimu yechitsuwa chenyukireya chegwenya remagetsi enyukireya, ine kuvimbika kwakanyanya uye kuita chisimbiso, kuendesa kwakachengeteka kwekutonhodza kunovimbiswa uye kuvuza kwezvinhu zvine radioactive kunodzivirirwa.

3. Mvura yemumaguta uye madhiraini: Mapombi anorasa tsvina emiti mikuru yekuchenesa tsvina anogona kudimbura tsvina ine mvura yakawanda kudzivirira kusvibiswa kwekudzokera shure. Inoshandiswa pamapombi makuru emvura yemumaguta kukurumidza kutema kuyerera kwemvura, kufambisa kuongororwa kwepombi uye kugadzirisa, uye kuve nechokwadi chekugadzikana kwemvura yemumaguta.

4. Metallurgical industry: The blast furnace gas pipelines mumagetsi esimbi anogona kuwana chisimbiso chakavimbika munzvimbo dzakaoma nepamusoro-soro uye guruva, kunyatsogadzirisa kuyerera kwegasi, uye kupa simba rakagadzikana rekuputika kwevira kwemoto.
