Mavharuvhu egedhiuyebutterfly valvesanoshandiswa sema switch ekudzora mwero wekuyerera mukushandiswa kwepombi. Ehezve, kuchine nzira mukusarudzwa kwemavharuvhu e butterfly uye mavharuvhu egedhi.
Mumvura yepombi yepombi network, kuitira kuderedza kudzika kwepombi yevhu yakavharwa, iyo yakawanda dhayamita yepombi yakakura inoshongedzerwa nevhavhavhavhavha, uye kana kudzika kwevhu kuvharwa kusingakoshi, edza kusarudza vharafu yegedhi, asi. mutengo wevhavha yegedhi yezvinyorwa zvakafanana zvakakwirira kudarika mutengo wevhavhavhavhavhavha. 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 chakakosha chesoft seal gedhi vharafu ndiyo rabha yakamisikidzwa vharafu ndiro, uye zvinodiwa zvehunyanzvi zverabha lined valve plate zvakakwirira, uye havasi vese vagadziri vekunze vanogona kuzviita, uye inowanzotengwa nekuunganidzwa kubva kufekitari nekuvimbika. quality.
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 copper nut block inoiswa mugondohwe rine rabha-lined kuti riite rose, iro rinokunda kukanganisa kuri pamusoro, asi concentricity yekubatanidzwa kwevhavhavhavha uye muviri wevharuvhu wakakwira. .
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 valvesuyegedhi mavharuvhu?
Zvinoenderana nebasa uye kushandiswa kwevharuvhu yegedhi uye butterfly vharafu, kuyerera kwevhavhavhavha yegedhi kudiki, kuita chisimbiso kwakanaka, nekuti kuyerera kwegedhi revhavha ndiro uye yepakati iri vertical angle, kana gedhi vharafu. haisi panzvimbo muvharuvhu ndiro chinja, svikiro kukwesha ndiro yevharuvhu inoita kuti vheji yevharuvhu izununguke, uye zviri nyore kukuvadza chisimbiso chegedhi.
Butterfly valve, inozivikanwawo sekuti flap valve, iri nyore chimiro chevharuvhu inodzora, iyo inogona kushandiswa pakubatidza/kudzima kudzora kwepaipi yepasi-pressure yepakati butterfly valve inoreva chikamu chinovhara (disc kana butterfly plate) se. dhisiki, inotenderera yakatenderedza shaft yevharuvhu kuti iwane kuvhura nekuvhara kwerudzi rwevharuvhu, vharafu inogona kushandiswa kudzora kuyerera kwemhando dzakasiyana dzemvura dzakadai semhepo, mvura, chiutsi, akasiyana corrosive media, 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 akasiyana corrosive uye asiri-corrosive fluid midhiya mapaipi mumainjiniya masisitimu akadai sechoto, marasha gasi, gasi rechisikigo, liquefied petroleum gasi, gasi remuguta, mhepo inopisa uye inotonhora, kunyunguduka kwemakemikari uye kuchengetedza kuchengetedzwa kwemagetsi, kuvaka mvura uye drainage, zvichingodaro, uye inoshandiswa kudzora nekucheka mafambiro enhau.
Gedhi vharafu (gedhi vharafu) chikamu chekuvhura nekuvhara chegedhi, kutungamira kwekufamba kwegedhi kwakanangana negwaro remvura, gedhi vharafu rinogona kuvhurwa zvizere uye kuvharwa, kusagadzikana kweiyo paramita yemusuwo. zvakasiyana, kazhinji 5 °, kana tembiricha yepakati isiri yakakwirira, 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, kungovimba nepakati pekumanikidza kudzvanya nzvimbo yekuisa chisimbiso chegondohwe kuchigaro chevhavha kune rumwe rutivi kuti ive nechokwadi chekuvharirwa kwechisimbiso chepamusoro, ndiko 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.
