Valve yeButterfly yeEccentric Triple
Chii chinonzi triple eccentric butterfly valve?
Vharuvhu yeshavishavi ine eccentric katatu, inozivikanwawo sevharuvhu yeshavishavi ine mativi matatu, imhando imwe yemavharuvhu eshavishavi anoshanda zvakanyanya, akagadzirirwa kushanda mumamiriro ekushanda ane kumanikidzwa kwakanyanya, tembiricha yakakwira, uye mafrequency akakwira ekuvhurika nekuvhara.
Vharuvhu yemapuruguru ine rabha yakasimba, ine dhizaini yakakura uye tekinoroji yekugadzira, yakavimbika mumhando uye inodhura zvishoma. Asi kana zvikashandiswa zvakanyanya senge tembiricha yakakwira kana pakuvhurwa nekuvharwa kwakakwira, hazvibvumidzwe kushandisa mavharuvhu emapuruguru ane chigaro chakapfava. Saka mavharuvhu emapuruguru ane chisimbiso chakasimba, chigaro chesimbi kana chigaro checeramic, chakagadzirirwa tembiricha yakakwira, kumanikidzwa kwakakwira kana mafrequency akakwira ekuvhurika, akatanga kushandiswa, asi kushanda kwevharuvhu yemapuruguru echinyakare ane chisimbiso chakasimba kwaigara kuri kunetseka kukuru.
Vharuvhu yeshavishavi ine eccentric katatu(inozivikanwawo se triple offset butterfly valve) yakagadzirwa munyaya iyi.
Kune zvinhu zvakawanda zvinoumbamavharuvhu eshavishavi ane hunyambiri hutatu.Kune chigaro chevharuvhu chinoshanda pamwe chete nemuviri, chine makona ekugara akagadziridzwa, chakaputirwa nezvinhu zvisingapfekwi zvakakodzera kuvhura nekuvhara kwemamiriyoni, simbi isingasvibi kudzivirira ngura, uye zvinhu zvekupisa kwakanyanya. Uye mhete yakapfava yekuvhara ine layer yakawanda kana mhete yakaoma yekuvhara yakaiswa padhisiki rebhatafurayi. Rudzi urwu rwedhizaini runobvumira vharuvhu yebhatafurayi ine eccentric katatu kuti isanyanya kubatwa nekupisa kwakanyanya kana kukwirira kwekumanikidzwa uye ngura, zvichienzaniswa nemavharuvhu ebhatafurayi echinyakare.
kusabuda kwemvura kweduvharuvhu yeshavishavi ine eccentric katatuInoitwa nerin'i yesimbi isina tsvina yakaiswa padhisiki. Dhizaini yekutenderera kwerudyi isina kukweshana inoitwa nepfungwa ye triple eccentric. Inobvisa kukweshana pakati pechigaro nerin'i yekuvhara nekutenderera kwe90º, torque diki zvinoreva kuti tinogona kutanga vharuvhu ne actuator diki, kuchengetedza mari yakawanda nenzvimbo.
Kana vharuvhu yavharwa, simba remuchina wekutumira rinogona kuwedzera kuti ripe muripo. Izvi zvinovandudza zvikuru mashandiro ekuvharavharuvhu yeshavishavi ine eccentric katatuuye inowedzera hupenyu hwebasa rayo.
Dhizaini yeTriple offsets
- Chinhu chekutanga ndechekuti vharuvhu iri kumashure kwedhisiki kuitira kuti chisimbiso chikwanise kuvhara chigaro chose chevharuvhu.
- Kubviswa kwechipiri ndekwekuti mutsetse wepakati pevharuvhu unobviswa kubva papombi nepakati pevharuvhu kudzivirira kukanganiswa nekuvhurwa nekuvhara kwevharuvhu.
- Dambudziko rechitatu nderekuti axis yekoni yechigaro inotsauka kubva pakati pemubato wevharuvhu, izvo zvinobvisa kukweshana panguva yekuvhara nekuvhura uye zvinoita kuti chisimbiso chekumanikidza chienderane chakakomberedza chigaro chose.
Zviri pamusoro apa ndiko kusumwa kwevharuvhu yeshavishavi ine eccentric katatuImhando yevharuvhu yemashavishavi inoshanda zvakanyanya inoshandiswa parizvino muminda yakawanda.
Zvinhu zvikuru zvemavharuvhu eshavishavi matatu eccentric
- Chigadzirwa chesimbi yose chisingatsvi.
- Zvigaro zveStellite® zvegiredhi rechitanhatu zvinogara kwenguva refu.
- Mareferensi edhisiki yakavhurika/yakavharwa uye chiratidzo chenzvimbo yedhisiki yekunze zvinoita kuti nzira dzekuisa/kubvisa dzive nyore kuAPI 609.
- Mhete yechisimbiso yesimbi inosanganisa mativi ese inoita kuti zvigaro zvikwanise kupararira zvakanaka zvichienderana nedenderedzwa rezvigaro rakanyatsogadzirwa.
- Nzvimbo yeflange inovimbisa kuti matanda e bolt nati ne washer zvinogara zvakanaka, zvichiita kuti majoini arambe akavimbika uye akachengeteka.
- Mhete dzechisimbiso dze duplex ne graphite dzine jira rakawanda dzinogona kutsiviwa zviri nyore.
- Mugodhi wakasimbiswa zvikuru wechikamu chimwe chete wakagadzirirwa kutamisa/kuchengetedza torque zvinobudirira.
- Zvidziviriro zvemabheya egirafiti zvakarukwa zvinodzivirira kupindira kwetsvina, zvichiita kuti torque irambe ichishanda uye mavharuvhu ashande zvakanaka.
- Kurongedza kwepurasitiki negrafiti zvine zvidimbu zviviri zvinoderedza njodzi yekubuda kwemhepo kubva kunze.
- Kubatanidza shaft-to-disc nekiyi kwakasimbiswa kuti shaft ive yakasimba.
- Magasket emumaronda anotenderera, zvisimbiso uye mhete dzekurongedza zvinotsiviwa pasina zvishandiso zvakakosha.
- Mabheyaringi anorema anodzivirira mitoro yekumanikidzwa kwakanyanya uye kusakara.
- Kubatwa kwenjodzi dzekubvisa shaft mukati nekunze kunoenderana nezvinodiwa zvepasi rose.
