Gedhi vharafuuyebutterfly valveese ari maviri anoita basa rekuchinja uye kudzora kuyerera mukushandiswa kwepombi.Asi pane nzira mukusarudza nzira ye butterfly mavharuvhu uye gedhi mavharuvhu.
Mumambure ekupa mvura, kuti kuderedze kudzika kwevhu rakafukidzira pombi, vharuvhu yeshavishavi rinowanzosarudzirwa mapaipi makuru edhayamita.Kana iine zvishoma zvishoma pakadzika kwevhu rakavhara, edza kusarudza vheji yegedhi, asi mutengo wevhavha yegedhi yezvinyorwa zvakafanana yakakwirira kudarika iyo yevhavhavhavhavhavha.Kana iri mutsara wekutema we caliber, inofanirwa kutariswa zvinoenderana nemamiriro chaiwo enzvimbo yega yega.Kubva pakuona kwekushandiswa mumakore gumi apfuura, kukundikana kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha zwa magevhu,nahone zwa fanela u dzhia zwine zwa vhathu vha tshi shumisa vhene vha tshi tendelana.
Nezvemavharuvhu emagedhi Mumakore achangopfuura, vagadziri vakawanda vevharuvhu vakagadzira uye vakatevedzera mavharuvhu egedhi akapfava.Kuenzaniswa neyechinyakare wedge kana parallel mbiri gedhi mavharuvhu, iyi vharafu yegedhi ine zvinotevera maitiro:
1. Muviri wevharuvhu uye bhoneti yevhavha yegedhi yakapfava-yakavharwa inokandwa nenzira yekukanda nzira, iyo inoumbwa panguva imwe chete, haidi kugadzirwa kwemagetsi, haishandisi mhete yendarira yekuisa chisimbiso, uye inochengetedza simbi dzisina ferrous. .
2. Hapana gomba riri pasi pevhavha yegedhi rakapfava, uye hapana slag inounganidzwa, uye kukundikana kwevhavha yegedhi kuzarura nekuvhara kwakaderera.
3. The soft seal rubber-lined valve plate ine yunifomu saizi uye kuchinjika kwakasimba.
Naizvozvo, iyo yakapfava yekuisa chisimbiso gedhi vharuvhu ichava fomu iyo indasitiri yemvura inoda kutora.Parizvino, dhayamita yezvinyoro-yakavharwa gedhi mavharuvhu anogadzirwa muChina anosvika 1500mm, asi dhayamita yevazhinji vanogadzira iri pakati pe80-300mm.Pachine matambudziko akawanda mukugadzirwa kwepamba.Chinhu chakakosha chevhavha yakapfava yekuvharisa gedhi ndiro rabha-lined valve plate, uye zvinodiwa zvehunyanzvi zverabha-lined valve plate zvakakwirira, izvo zvisiri izvo vese vanogadzira vekunze vanogona kuwana, uye vanowanzotengwa uye kuunganidzwa kubva kune vanogadzira vakavimbika. quality.
Iyo yemhangura nut block yemumba yakapfava yekuvharisa gedhi vharafu yakamisikidzwa pamusoro perabha-lined valve plate, yakafanana nechimiro chevhavha yegedhi.Nekuda kwekukweshana kunofambiswa kwe nut block, rubber lining yeplate yevharuvhu inopepetwa zviri nyore.Mamwe makambani ekune dzimwe nyika anopinza chivharo chemhangura mugedhi rine rabha-mutsetse kuti riite rose, iro rinokunda zvikanganiso zviri pamusoro, asi concentricity yekusanganiswa kwevhavhavhavha uye muviri wevharuvhu wakakwira zvakanyanya.
Zvisinei, pakuzarura nekuvhara jira rakapfava rekuvhara gedhi, haifaniri kuvharwa zvakanyanya, chero bedzi mvura inomisa mvura inowanikwa, kana zvisina kudaro hazvisi nyore kuzarura kana rubber rubber runobviswa.Mugadziri wevharuvhu anoshandisa torque wrench kudzora dhigirii rekuvhara panguva yekuedzwa kwevhavha.Sevhavhavhavha yekambani yemvura, iyi nzira yekuvhura nekuvhara inofanirawo kutevedzerwa.
Ivhavha yegedhi igedhi rekuzarura nekuvhara, nzira yekufambisa yegedhi inotenderera kune nzira yemvura, uye gedhi regedhi rinogona kuvhurwa zvakakwana uye rakavharwa zvakakwana.Kuvandudza magadzirirwo ayo uye kugadzira kutsauka kweiyo chisimbiso chepamusoro angle 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, iyo inozvisunga.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 revharuvhu regedhi rinofamba mumutsara wakatwasuka netsvimbo yevharuvhu, inonziwo rising stem 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).Imwe gedhi vharafu stem nati yakaiswa pagedhi, uye kutenderera kwehandwheel kunotyaira hunde yevharuvhu kuti itenderere, izvo zvinoita kuti gedhi risimuke.Rudzi urwu rwevharuvhu inodaidzwa kuti vheruvha yegedhi inotenderera kana kuti vharafu regedhi rakasviba.
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 vharuvhu 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 yekuvhara (disc kana ndiro) 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.Kana ikashandura 90 °, inogona kupedza imwe kuvhura nekuvhara.Nekushandura deflection angle ye disc, kuyerera kwepakati kunogona kudzorwa.
Mamiriro ekushanda uye midhiya: Mavharuvhu eButterfly akakodzera kutakura zvinwiwa zvakasiyana-siyana zvinoparadza uye zvisingaparadzi mumainjiniya masisitimu akadai semugadziri, gasi remarasha, gasi rechisikigo, gasi repetroleum rakanyungudutswa, gasi remuguta, mhepo inopisa uye inotonhora, kunyunguduka kwemakemikari uye kuchengetedza kwezvakatipoteredza. , kuvaka kwemvura uye kunyura, nezvimwewo Papombi yepakati, inoshandiswa kugadzirisa uye kutema kuyerera kwepakati.
