Gedhi vharafu uyebutterfly valve ese ari maviri anoita basa rekuchinja uye kudzora kuyerera mukushandiswa kwepombi. Ehezve, pachine nzira mukusarudzwa kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha yegedhi. Kuti kuderedze kudzika kwevhu rakafukidzira pombi mumambure emvura, kazhinji pombi dzakakura dhayamita dzine mavharuvhu eshavishavi, ayo asina zvazvinoita pakudzika kwevhu, uye anoedza kusarudza mavharuvhu emagedhi.
Ndeupi musiyano uripo pakati pevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha yegedhi?
Zvinoenderana nebasa uye kushandiswa kwevhavha yegedhi uye butterfly vharafu, vharafu yegedhi ine kushoma kuyerera kwekudzivirira uye kuita kwakanaka kwekuvhara. Nekuti mafambiro evharuvhu regedhi nepakati ari pakona yakatwasuka, kana vharafu yegedhi isina kuchinjika panzvimbo pandiro yevharuvhu, kukweshwa kwepakati pandiro yevharuvhu kuchaita kuti vheji yevharuvhu ibvunde. , Zviri nyore kukuvadza chisimbiso chevhavha yegedhi. Butterfly valve, inonziwo flap valve, imhando yevharuvhu yekudzora ine chimiro chakareruka. Butterfly valve inogona kushandiswa pa-off control yepasi-pressure pipeline medium zvinoreva kuti nhengo inovhara (disc kana butterfly plate) idhisiki, rinotenderera kutenderera shaft yevharuvhu kuti iwane kuvhura nekuvhara. Ivhavha inogona kushandiswa kudzora kuyerera kwemhando dzakasiyana dzemvura dzakadai semhepo, mvura, chiutsi, zvakasiyana-siyana zvinoparadza midhiya, madhaka, mafuta, simbi yemvura uye radioactive media. Iyo inonyanya kutamba basa rekucheka uye kupuruzira pane pombi. The butterfly valve kuvhura nekuvhara chikamu idisc-shaped butterfly plate, iyo inotenderera ichitenderedza akisi yayo mumutumbi wevharuvhu kuti iwane chinangwa chekuvhura nekuvhara kana kugadzirisa. Iyo butterfly plate inofambiswa nevharuvhu hunde. Kana yasvika makumi mapfumbamwe°, inogona kupedza imwe kuvhura nekuvhara. Nekushandura deflection angle ye disc, kuyerera kwepakati kunogona kudzorwa.
Mamiriro ekushanda uye zvepakati: Butterfly vharafu yakakodzera kuendesa mvura dzakasiyana-siyana dzinoparadza uye dzisingaparadzi mumainjiniya masisitimu akadai semugadziri, marasha gasi, gasi remumvura, gasi remuguta, mhepo inopisa uye inotonhora, kunyunguduka kwemakemikari uye kuchengetedza kwemagetsi kuchengetedzwa kwezvakatipoteredza. , kuvaka kwemvura uye kunyura, nezvimwewo Papombi yepakati, inoshandiswa kugadzirisa uye kutema kuyerera kwepakati.
Ivhavha yegedhi ine gedhi rekuvhura nekuvhara nhengo, nzira yekufambisa yegedhi inotarisana negwaro remvura, uye gedhi regedhi rinogona kuvhurwa zvakakwana uye rakavharwa zvakakwana. Kuvandudza manufact ayoor kugona uye kugadzirisa kutsauswa kwekona yekuisa chisimbiso panguva yekugadziriswa, gedhi iri rinonzi elastic gedhi.
Kana gedhi revhavha rakavharwa, nzvimbo yekuisa chisimbiso inogona kungovimba nepakati pekumanikidza kuvhara, ndiko kuti, kungovimba nepakati pekumanikidza kudzvanya nzvimbo yekuisa chisimbiso chegedhi kuchigaro chevhavha kune rumwe rutivi kuti ive nechokwadi chekuisa chisimbiso. nzvimbo yekuisa chisimbiso, iko kuzvisunga. Mazhinji mavharuvhu emagedhi akavharwa nechisimba, ndiko kuti, kana vharuvhu yakavharwa, gedhi rinofanira kumanikidzwa kurwisa chigaro chevhavha nechisimba chekunze kuti ive nechokwadi chekusimba kwechisimbiso chepamusoro.
Movement mode: Gedhi regedhi revhavha rinofamba mumutsara wakatwasuka netsvimbo yevharuvhu, iyo inonziwoOS&Y gedhi vharafu. Kazhinji, pane trapezoidal tambo padanda rekusimudza. Kuburikidza nenati iri pamusoro pevharuvhu uye girovha yegirovha pamutumbi wevharuvhu, iyo inotenderera inofamba inoshandurwa kuita mutsara wekufamba, ndiko kuti, torque yekushandisa inoshandurwa kuita yekusundira kwekushanda. Kana iyo valve yakazarurwa, apo kukwidziridzwa kwegedhi kwakaenzana ne1: 1 nguva yakareba yevhavha, chiteshi chemvura hachina kuvharwa zvachose, asi nzvimbo iyi haigoni kuongororwa panguva yekushanda. Mukushandiswa chaiko, iyo yepamusoro yevhavha stem inoshandiswa sechiratidzo, ndiko kuti, nzvimbo iyo isingagoni kuvhurwa, senzvimbo yayo yakazaruka zvakakwana. Kuti utarise chiitiko chekuvhara nekuda kwekushanduka kwekushisa, inowanzovhurwa kunzvimbo yepamusoro, uye zvakare kudzokera ku 1/2-1 kutendeuka, sechinzvimbo chevhavha yakazaruka zvakakwana. Nokudaro, nzvimbo yakazaruka yevhavha inotarirwa maererano nenzvimbo yegedhi (kureva sitiroko). Mamwe magedhi evhavha stem nuts akaiswa pagedhi, uye kutenderera kwehandwheel kunotyaira hunde yevharuvhu kuti itenderere, izvo zvinoita kuti gedhi risimuke. Rudzi urwu rwevharuvhu inonzi Rotary stem gedhi vharafu kanaNRS gedhi vharafu.
