Mavharuvhu egedhiuyebutterfly mavharuvhuanoshandiswa sema switch ekudzora mwero wekuyerera mukushandiswa kwepombi. Ehezve, kuchine nzira mukusarudzwa kwemavharuvhu e butterfly uye mavharuvhu egedhi.
Mumumbure wepombi yemvura, kuitira kuti uderedze kudzika kwepombi yevhu yekuvhara, dhayamita yepombi yakakura yakashongedzerwa nevhavhavhavhavhavha, uye kana kudzika kwekuvhara kwevhu kusina kukosha, edza kusarudza gedhivhavha, asi mutengo wevhavha yegedhi yezvakatsanangurwa zvakafanana yakakwirira kudarika mutengo wevhavhavhavhavha. Kana iri mutsara wekutema wecaliber, nzvimbo yega yega inofanirwa kutariswa pane imwe nyaya-ne-nyaya. Kubva pakuona kwekushandiswa kwemakore gumi apfuura, kukundikana kwevhavhavhavhavhavhavha yakakwira kupfuura iyogedhi vharafu, saka zvakakodzera kubhadhara kuwedzera kushandiswa kwevheji yegedhi kana mamiriro ezvinhu achibvumira.
Mumakore achangopfuura, vazhinji vanogadzira mavharuvhu epamba vakagadzira uye vakatevedzera mavharuvhu egedhi akapfava, ane hunhu hunotevera pane echinyakare wedge kana parallel mbiri gedhi mavharuvhu:
Thevharafumuviri uye bhoneti yevhavha yakapfava yegedhi inokandwa nenzira yekukanda nzira, iyo inoumbwa panguva imwe chete, isingagadziriswi, uye haishandisi kuvhara mhete dzemhangura, kuchengetedza simbi dzisina ferrous.
Hapana gomba pazasi penyoro chisimbiso vharafu gedhi, hapana kuunganidza slag, uye kukundikana kwehuwandu hwegedhi vharafukuvhura nekuvhara kwakaderera.
Iyo yakapfava seal lined valve plate inofanana muhukuru uye inochinjika zvakanyanya.
Nokudaro, iyo yakapfava seal gedhi valve ichava fomu iyo indasitiri yemvura inofara kugamuchira. Parizvino, dhayamita yevhavha yakapfava yegedhi yakagadzirwa muChina ndeye 1500mm, asi dhayamita yevazhinji vanogadzira iri pakati pe80-300mm, uye kuchine matambudziko mazhinji mukugadzira mudzimba. Chinhu chinokosha chevhavha yakapfava yegedhi yevhavha yevhavha yerabha yakavharidzirwa, uye zvinodiwa zveunyanzvi zvepureti yevhavha yakavharidzirwa yakakwirira, uye havasi vese vanogadzira kunze kwenyika vanogona kuizadzisa, uye inowanzotengwa uye inounganidzwa kubva kufekitari ine unhu hwakavimbika.
Iyo copper nut block yemumba yakapfava sealgedhi vharafuyakadzikwa uye yakaturikwa pamusoro perabha lining valve plate, yakafanana nechimiro chevhavha yegedhi, uye rubber lining yeplate yevharuvhu iri nyore kusvuura nekuda kweiyo inoshanda friction ye nut block. Kune iyo yakapfava seal gedhi vharafu yeimwe kambani yekunze, iyo yemhangura nut block inoiswa mugondohwe rine rabha-lined kuti riite rose, iro rinokunda zvikanganiso zviri pamusoro, asi concentricity yekubatanidzwa kwevhavhavhavha uye muviri wevharuvhu yakakwirira.
Zvisinei, pakuzarura nekuvhara chisimbiso chisimbiso chevhavha yegedhi, haifaniri kuvharwa zvakanyanya, chero bedzi mvura inomisa mvura inowanikwa, kana zvisina kudaro hazvisi nyore kuzarura kana kubvisa rubber lining. Mugadziri wevhavhavha, muvhavha yevhavha yekuedza test test, kushandiswa kwetambo wrench kudzora dhigirii yekuvhara, sekambani yemvura yevashandi vemagetsi inofanirawo kutevera nzira iyi yekuzarura nekuvhara.
Ndeupi musiyano uripo pakati pekushandiswa kwebutterfly mavharuvhuuyegedhi mavharuvhu?
Zvinoenderana nekushanda uye kushandiswa kwevharuvhu yegedhi nevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharuvhu,kuramba kuyerera kwevharuvhu kwegedhi kudiki,kusunga chisimbiso kwakanaka,nekutikuyerera kweplate regedhi revharuvhu uye yepakati ikona yakatwasuka,kana vheruvha yegedhi isiri panzvimbo muvharuvhu plate switch,pakati kukwesha ndiro yevharuvhu inoita kuti vharafu yevhavha izunguze, uye zviri nyore kukuvadza chisimbiso chevhavha yegedhi.
Butterfly valve, inozivikanwawo sevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha kumisa kumisa/kumisa kuvharisa kwepipelinena xikandzo lexi xikan’we. 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 axis yayo mumutumbi wevharuvhu, kuitira kuti iwane chinangwa chekuvhura nekuvhara kana kugadzirisa.
Iyo butterfly plate inofambiswa nevhavha stem, uye kana ikatendeuka 90 °, inogona kupedzisa kuvhura nekuvhara. Nekuchinja kutsauka kwekona ye butterfly, kuyerera kwepakati kunogona kudzorwa.
Mamiriro ekushanda nepakati:Butterfly valveinokodzera kutakura mapombi akasiyana-siyana ekuora uye asingaorese emvura mumainjiniya masisitimu akadai sechoto, gasi remarasha, gasi rechisikigo, liquefied petroleum gasi, gasi reguta, mhepo inopisa uye inotonhora, kunyungudutswa kwemakemikari uye kuchengetedza kwemagetsi kuchengetedza kwezvakatipoteredza, kuvaka mvura nekugezera, nezvimwewo, uye inoshandiswa kudzora uye kucheka kuyerera kwenhau.
Gedhi valve (gedhi revhavha) chikamu chekuzarura nekuvhara chegedhi, kutungamirirwa kwekufamba kwegedhi kunotenderera kune kutungamirirwa kwemvura, gedhi regedhi rinogona kuvhurwa zvakakwana uye rakavharwa, kusagadzikana kwemiganhu yegonhi kwakasiyana, kazhinji 5 °, apo kutonhora kwepakati hakusi kukwirira, i2 ° 52′. Kuti ivandudze magadzirirwo ayo uye kugadzirisa kutsauswa kwechisimbiso chepamusoro angle mukugadzirisa, rudzi urwu rwegondohwe rinonzi elastic ram.
Apo iyogedhi vharafuyakavharwa, nzvimbo yekuisa chisimbiso inogona kungovimba nepakati pekumanikidza kuvhara, ndiko kuti, kuvimba chete nekumanikidza kwepakati kudzvanya nzvimbo yekuisa chisimbiso chegondohwe kune chigaro chevharuvhu kune rumwe rutivi kuti ive nechokwadi chekuisa chisimbiso chekuisa chisimbiso chepamusoro, iko kuzvisimbisa. Mavharuvhu mazhinji emagedhi anovharwa nechisimba, ndiko kuti, kana vharuvhu yakavharwa, gondohwe rinofanira kumanikidzirwa kuchigaro chevhavha nechisimba chekunze kuti ive nechokwadi chekusimba kwechisimbiso chepamusoro.
Movement mode: Iro regedhi revhavhavha yegedhi rinofamba mumutsara wakatwasuka netsvimbo yevharuvhu, iyo inonziwo vharanda regedhi rakavhurika. Kazhinji pane tambo yetrapezoidal padanda rekusimudza, kuburikidza nenati kumusoro kwevharuvhu uye gwara regirovha pamutumbi wevharuvhu, iyo inotenderera inoshandurwa kuita mutsara kufamba, ndiko kuti, torque yekushanda inoshandurwa kuita basa rekushanda. Apo valve yakavhurwa, apo gondohwe rinosimudza urefu rakaenzana ne1: 1 nguva yevhavha yevhavha, kuyerera kwemvura kunenge kusina kuvharwa zvachose, asi nzvimbo iyi haigoni kuongororwa panguva yekushanda. Mukushandiswa chaiko, inotaridzwa ne vertex ye stem, ndiko kuti, chinzvimbo chisingagoni kuvhurwa, sechinzvimbo chayo chakazaruka. Kuti uverenge nezve kukiya-up phenomenon yekuchinja kwekushisa, inowanzovhurwa kune apex chinzvimbo, uye yozodzoserwa kumashure kune 1/2-1 kutendeuka senzvimbo yevhavha yakazaruka. Nokudaro, nzvimbo yakazaruka yevharuvhu inotariswa nenzvimbo yegondohwe (kureva sitiroko). Imwe gedhi vharafu stem nut iri pagedhi, uye handwheel inotenderera kuti ityaire hunde yevharuvhu kuti itenderere, uye ndiro yegedhi inosimudzwa, iyi vharafu inonzi rotary rod gedhi vharafu kana yerima tsvimbo yegedhi vharafu.
