Butterfly mavharuvhu uye gedhi mavharuvhu mamiriro akasiyana ekushanda

Gedhi mavharuvhu uyebutterfly valvesmupombi inoshandiswa kuita basa rekushandura, kugadzirisa kuyerera. Ehezve, kuchine nzira mukusarudzwa kwemavharuvhu e butterfly uye mavharuvhu egedhi.

Izvo zvakafanana zvemutengo wevhavha yegedhi yakakwirira kudarika mutengo we butterfly valve. Asi kubva kushandiswa kwemakore gumi apfuura, shavishavi vharafu kukundikana kupfuura gedhi vharafu yakakwirira, saka mumamiriro ezvinhu mvumo, kuwedzera kushandiswa gedhi vharafu zvakakodzera kutarisirwa.

Butterfly valve mukushandiswa kwegedhi revhavha musiyano:

Zvinoenderana nebasa regedhi vharuvhu uye butterfly vharafu uye kushandiswa kwevharuvhu, gedhi revhavha inoyerera kuramba idiki, yakanaka yekuisa chisimbiso, nekuti gedhi revhavhavhavha ndiro uye media inoyerera iri vertical angle, kana gedhi vharafu. muvharuvhu chinja haisi panzvimbo, vezvenhau pamusoro vharafu ndiro scouring kuti vharafu ndiro kudedera, zviri nyore chaizvo kupenya kupinda gedhi vharafu chisimbiso kukuvara.

Butterfly ndiro inosundwa nevhavha hunde, kana yatendeuka 90 °, ichakwanisa kupedzisa kuvhura nekuvhara. Chinja deflection angle ye butterfly plate, unogona kudzora kuyerera kwe media.

Kushandiswa kwemamiriro uye midhiya: butterfly vharafu inokodzera muchoto, gasi, gasi rechisikigo, liquefied petroleum gasi, gasi reguta, mhepo inopisa uye inotonhora, kunyungudutswa kwemakemikari uye kugadzirwa kwemagetsi uye kuchengetedza kwezvakatipoteredza, kuvaka kwemvura uye dhiraivha uye mamwe mainjiniya masisitimu ekutakura. zvakasiyana-siyana zvinoora, zvisingasvibisi fluid media papombi, inoshandiswa kugadzirisa uye kucheka kuyerera kwenhau.

Gedhi vharafuinhengo yekuvhura uye yekuvhara yegedhi, mafambiro egedhi ari perpendicular kune kutungamira kwemvura, gedhi revhavha rinogona kushandiswa chete kune rakazaruka rakazara uye rakazara rakavharwa, harishandisi kune paramita yemusuwo uye. zvakasiyana. Kuvandudza hunyanzvi hwayo, gadzira kona yenzvimbo yekuisa chisimbiso mukugadzirisa kutsauka, gedhi iri rinonzi elastic gedhi.

Kana gedhi revhavha rakavharwa, nzvimbo yekuisa chisimbiso inogona kungovimba nepakati pekumanikidza kuvhara, ndiko kuti, kuvimba chete nekumanikidza kwepakati kuchava nzvimbo yekuisa chisimbiso chegedhi kune rumwe rutivi rwechigaro kuti ive nechokwadi chekuti chisimbiso chepamusoro. yenzvimbo yekuisa chisimbiso, iko kuzvisimbisa. Yakawanda yevhavha yegedhi inoshandiswa kumanikidzira kuvhara, kureva, kana vheji yakavharwa, kuvimba nemasimba ekunze kumanikidzira gedhi kuchigaro chevhavha kuti ave nechokwadi chokuti chisimbiso chekuvhara kwechisimbiso.

Motion: gedhi revharuvhu gedhi rine hunde revharuvhu rekufamba kwemutsara, inozivikanwawo seinosimudza stem gedhi vharafu. Gedhi vharafu stem nut pa gedhi, handwheel rotation inofambisa valve stem kutenderera, kuitira kuti gedhi risimudze, iyi valve inonzinrs gedhi vharafu.
