Zvinoenderana nebasa uye kushandiswa kwevharafu yegedhiuyebutterfly valve, gedhi regedhi rine kushoma kuyerera kwekudzivirira uye kuita kwakanaka kwekuisa chisimbiso.Nekuti mafambiro evharuvhu regedhi nepakati ari pakona yakatwasuka, kana vharuvhu yegedhi isina kuchinjika panzvimbo pandiro yevharuvhu, kukweshwa kwepakati pandiro yevharuvhu kuchaita kuti vheji yevharuvhu ibvunde., Zviri nyore kukuvadza chisimbiso chevhavha yegedhi.
Butterfly valve, inozivikanwawo sevharavhavhavha, imhando yevhavha inogadzirisa ine chimiro chakareruka.Butterfly valve inogona kushandiswa pa-off control ye low-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, akasiyana siyana anoodza media, madhaka, oiri, simbi yemvura uye radioactive media.Iyo inonyanya kutamba basa rekucheka uye kupuruzira pane pombi.Varuvhu yeshavishavi inovhura nekuvhara chikamu idisc-shaped butterfly ndiro, iyo inotenderera yakapoteredza axis yayo mumutumbi wevhavha kuti uwane chinangwa chekuvhura nekuvhara kana kugadzirisa.
Iyo butterfly plate inofambiswa nevharuvhu hunde.Kana ikashandura 90 °, 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 seanogadzira, marasha gasi, gasi rechisikigo, liquefied petroleum gasi, gasi remuguta, mhepo inopisa uye inotonhora, kunyunguduka kwemakemikari uye kuchengetedza kuchengetedzwa kwezvakatipoteredza. , chivakwamvura uye dhiraivha, etc. Papombi yepakati, inoshandiswa kugadzirisa uye kutema kuyerera kwepakati.
Thevharafu yegedhiigedhi rekuvhura uye rekuvhara, mafambiro egedhi ari perpendicular kune kutungamira kwemvura, uye gedhi regedhi rinogona kungovhurwa zvizere uye rakavharwa zvizere.Kuvandudza magadzirirwo ayo uye kugadzira kutsauka kweiyo chisimbiso chepamusoro angle panguva yekugadzirisa, gedhi iri rinodaidzwa kuti elastic gedhi.
Kana gedhi revhavha rakavharwa, nzvimbo yekuisa chisimbiso inogona kungovimba nepakati pekumanikidza kuvhara, ndiko kuti, kungovimba nekumanikidza kwepakati 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 revhavha yegedhi inofamba mumutsara wakatwasuka netsinde yevharuvhu, inonziwo ainosimudza stem gedhi vharafu.Kazhinji, pane tambo dze trapezoidal 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 kwechokwadi, iyo yepamusoro yevhavha stem inoshandiswa sechiratidzo, ndiko kuti, nzvimbo iyo isingagoni kuvhurwa, senzvimbo yayo yakazaruka zvakakwana.Kuti utarise chiitiko chekuvhara chinokonzerwa nekushanduka 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 pasuwo, uye kutenderera kwehandwheel kunotyaira hunde yevharuvhu kutenderera, uye gedhi rinosimudzwa.Rudzi urwu rwevharuvhu runodanwaRotary stem gedhi valve or yakavanzika stem gedhi vharafu.
