Nhanganyaya kune Butterfly mavharuvhu
Butterfly mavharuvhu
A Butterfly valve ikota-turn rotational motion valve, inoshandiswa kumisa, kudzora, uye kutanga kuyerera.
Butterfly mavharuvhu ari nyore uye anokurumidza kuvhura. Kutenderera kwe90 ° kwemubato kunopa kuvhara kwakakwana kana kuvhura kwevhavha. Mavharuvhu makuru eButterfly anowanzo kuve akashongedzerwa neinonzi gearbox, uko handwheel nemagiya yakabatana kune hunde. Izvi zvinorerutsa kushanda kwevhavha, asi pamutengo wekukurumidza.
Mhando dzeButterfly valves
Butterfly mavharuvhu ane muviri mupfupi denderedzwa, dhisiki dhisiki, simbi-kusvika-simbi kana zvinyoro zvigaro, kumusoro uye pasi shaft mabearings, uye stuffing bhokisi. Kuvakwa kweButterfly valve body inosiyana. Dhizaini inowanzoshandiswa imhando yewafer inoenderana pakati pemaflange maviri. Imwe mhando, kugadzirwa kwewafer, inobatwa pakati pemaflange maviri nemabhaudhi anobatana nemaflange maviri uye anopfuura nemaburi ari kunze kwevharuvhu. Butterfly mavharuvhu anotowanikwa aine flanged, threaded uye butt welding ends, asi haawanzo shandiswa.
Butterfly mavharuvhu ane akawanda mabhenefiti pamusoro pegedhi, gorobhu, plug, uye bhora mavharuvhu, kunyanya kune makuru mavharuvhu application. Kuchengeta uremu, nzvimbo, uye mutengo ndizvo zvakanakira zviri pachena. Mari yekugadzirisa inowanzove yakaderera nokuti kune nhamba shoma yezvikamu zvinofamba uye hapana mahomwe ekuteya mvura.
Mavharuvhu eButterfly akanyatsokodzera kubata kuyerera kukuru kwezvinwiwa kana magasi zvine mwero wakaderera uye nekubata slurries kana zvinwiwa zvine huwandu hukuru hwezvakarembera zvakasimba.
Butterfly mavharuvhu akavakirwa pamusimboti wepombi damper. The flow control element idhisiki rinenge dhayamita yakafanana nedhayamita yemukati yepombi yakabatana, inotenderera pane axis yakatwasuka kana yakachinjika. Kana dhisiki yakarara yakaenzana nekumhanya kwepombi, valve inovhurwa zvizere. Apo diski inosvika panzvimbo yeperpendicular, valve inovharwa. Zvinzvimbo zvepakati, zvezvinangwa zvekukwenya, zvinogona kuchengetedzwa munzvimbo nekubata-kukiya michina.
Butterfly valve Seat Construction
Kumira kwekuyerera kunoitwa nevharuvhu disk kuvharira chigaro chiri mukati medhayamita yeperiphery yemuviri wevharuvhu. Mavharuvhu mazhinji eButterfly ane chigaro che elastomeric chinosungirirwa dhisiki. Mamwe mavharuvhu eButterfly ane chisimbiso ring ring anoshandisa clamp-mhete uye kutsigira-mhete pane serrated edged rabha mhete. Iyi dhizaini inodzivirira extrusion yeO-mhete.
Mumagadzirirwo ekutanga, dhisiki yesimbi yaishandiswa kuvhara pachigaro chesimbi. Urongwa uhwu hahuna kupa kuvhara-kuvharika, asi hwakapa kuvharika kwakakwana mune mamwe maapplication (kureva, mitsetse yekugovera mvura).
Butterfly vharafu Muviri Kuvaka
Butterfly valve kuvakwa kwemuviri kunosiyana. Iyo yakanyanya hupfumi imhando yewafer inokodzera pakati pemapipeline flanges. Imwe mhando, dhizaini yewafer, inobatwa pakati pepombi mbiri dzepombi nemabhaudhi anobatana nemaflange maviri uye anopfuura nemaburi ari kunze kwevharuvhu. Butterfly mavharuvhu anowanikwa ane akajairwa flanged migumo kuti bolting kune pombi flanges, uye mune shinda magumo kuvaka.
Seat Disk uye Stem yeButterfly valve
Dzinde nedhisiki yevharuvhu yeButterfly zvidimbu zvakasiyana. Iyo dhisiki inobhowa kugamuchira dzinde. Nzira mbiri dzinoshandiswa kuchengetedza dhisiki kune tsinde kuitira kuti dhisiki inotenderera sezvo tsvina inoshandurwa. Munzira yekutanga, dhisiki inobvongodzwa uye yakachengetedzwa kune stem nemabhoti kana mapini. Imwe nzira inosanganisira kufinha dhisiki sepakutanga, wobva wagadzira chiborero chepamusoro kuti chikwane hunde ine sikweya kana hekisi. Iyi nzira inobvumira diski "kuyangarara" uye kutsvaga nzvimbo yayo pachigaro. Kuiswa chisimbiso kwakafanana kunoitwa uye zvekunze stem fasteners zvinobviswa. Iyi nzira yekuunganidza inobatsira munyaya yemadhisiki akavharwa uye mune corrosive application.
Kuti dhisiki riitike panzvimbo yakakodzera, tsinde inofanira kupfuurira mberi kwepasi pe diski uye inopinda mubhushi riri pasi pemuviri wevhavha. Imwe kana maviri mabhushi akafanana ari pamwe nechepamusoro chikamu chehunde zvakare. Aya mabhushi anofanirwa kunge achipokana nevezvenhau vari kubatwa kana kuiswa chisimbiso kuitira kuti corrosive media isasangana navo.
Stem seals inozadzikiswa pamwe nekurongedza mubhokisi rakajairwa rekuisa kana kuburikidza neO-ring seals. Vamwe vanogadzira mavharuvhu, kunyanya avo vane hunyanzvi hwekubata zvinhu zvinoora, vanoisa chisimbiso mukati mevharuvhu kuitira kuti pasave nechinhu chiri kubatwa nevharuvhu chinosangana nedzinde revharuvhu. Kana bhokisi rekuputira kana O-ring yekunze ikashandiswa, mvura inopfuura nepakati pevharuvhu inosangana nevharuvhu.
Mashandiro akajairika eButterfly valves
Bharuvha yeButterfly inogona kushandiswa mumasevhisi mazhinji akasiyana emvura uye inoita zvakanaka mukushandisa slurry. Zvinotevera ndezvimwe zvinowanzoitika zveButterfly valves:
- Mvura inotonhorera, mhepo, magasi, kudzivirira moto nezvimwe.
- Slurry nemamwe masevhisi akafanana
- Vacuum service
- High-pressure uye yakakwirira-tembiricha mvura uye sevhisi masevhisi
Zvakanakira Butterfly mavharuvhu
- Compact design inoda nzvimbo shoma, zvichienzaniswa nemamwe mavharuvhu
- Chiedza muhuremu
- Kukurumidza kushanda kunoda nguva shoma yekuvhura kana kuvhara
- Inowanikwa muhukuru hukuru
- Kuderera-kuderedza kuderera uye kupora kwepamusoro
Zvakaipa zveButterfly valves
- Throttling sevhisi inogumira kune yakaderera mutsauko kudzvanywa
- Cavitation uye kukachidzwa kuyerera zvinhu zviviri zvinogona kunetsekana
- Disc movement haina kutungamirwa uye inobatwa nekuyerera turbulence

Gaskets uye kuiswa kweButterfly valves
Musi waGunyana 14, 2012 ndakagamuchira e-mail ine chirevo chinotevera:
Ndine zano kwauri randisingafungiri rakatariswa pane yako saiti, iro rekutsanangura rudzi rwegasket rekushandisa kune akasiyana Butterfly mavharuvhu (Type E kana F) uye rudzii rweshamwari flange inofanira kushandiswa (RF kana FF), uye zvakare kana gasket isingakodzeri nekuti mamwe mavharuvhu eButterfly ane akakosha gaskets. Ndakaona kuti panowanzoita confusion panyaya iyi.
Kuona kwakanaka uye saka zvinotevera:

Kudzivisa matambudziko neButterfly valves
Mazhinji ematambudziko ese ane Butterfly mavharuvhu mumunda ane hukama zvakananga nemaitiro asina kunaka ekuisa. Nokuda kwechikonzero ichi, kuchenjera kufunga zvakanakisisa-kuita paunenge uchiisa pombi-basa uye kuisa valve pachayo.
Chigaro chiri muvharuvhu yeButterfly yakagara yakasimba kazhinji inotenderera ichitenderera kune zviso zvese zvevharuvhu. Nekuda kweizvozvo, hapana gaskets inodiwa sezvo zvigaro izvi zvinoshanda basa regasket. Iyo chigaro zvinhu izvo zvinotambanukira mberi kwechiso zvinomanikidzwa panguva yekuiswa uye inoyerera yakananga pakati pechigaro chevharuvhu. Chero shanduko mune iyi gadziriso nekuda kwekumisikidzwa kusina kufanira inokanganisa zvakananga kudzvanywa chiyero uye zvigaro zvekugara / kusunungura torque.
Kusiyana nemhando dzakawanda dzevharuvhu, dhisiki reButterfly valve rinowedzera kupfuura chiso chemuviri wevharuvhu pamakona akapihwa ekuvhura (ti, 30 ° kana kupfuura) kana yaiswa pakati pemafurangi. Nokudaro, zvakakosha zvikuru kusati kwaiswa kuti ive nechokwadi chokuti diski inokwanisa kusununguka kutendeuka uye kupinda maflanges uye pombi-basa.
Kutumira uye Kuchengeta
- Position discs pa10% yakavhurika kuitira kuti irege kuvharwa.
- Zviso zvevharuvhu yega yega zvinofanirwa kuvharwa kudzivirira kukanganisa kuchiso chechigaro, disc edge, kana mukati mevharuvhu.
- Chengetedza mukati memba, pamwe paine tembiricha iri pakati pe5°C ne30°C.
- Vhura uye uvhare mavharuvhu mwedzi mitatu yega yega.
- Ngarava uye mavharuvhu ekuchengetedza kuitira kuti pasave nemitoro inorema inoshandiswa kumitumbi.
Valve Nzvimbo
- Butterfly mavharuvhu anofanira kuiswa kana zvichibvira shoma 6 pombi madhayamita kubva mamwe mutsara zvinhu, kureva gokora, pombi, mavharuvhu, etc. Dzimwe nguva izvi hazvigoneki, asi zvakakosha kuwana kureba sezvinobvira.
- Ipo iyo Butterfly valve yakabatana nevhavha yecheki kana pombi, chengetedza nzvimbo yakakwana pakati pavo kuti uone kuti dhisiki haikanganisi nemichina iri pedyo.
Valve Orientation
Sekutonga kwechigunwe, mavharuvhu eButterfly anogadzikwa nedzinde munzvimbo yakatwasuka ine actuator yakasimudzwa yakamira yakananga pamusoro payo, zvisinei, pane mamwe maapplication apo dzinde rinofanira kunge rakachinjika. Iyo .pdf faira pazasi inokuudza kuti sei dzinde somtimes richifanira kuiswa rakachinjika.
