Ndezvipi zvakaipa zvemavharuvhu ekuongorora wafer?

Iyovharuvhu yekutarisa ndiro mbiri yewaferzvakare rudzi rwevharuvhu rekutarisa rine kutenderera, asi idhisiki mbiri uye rinovhara pasi pekushanda kwechitubu. Dhisiki rinosundirwa kuvhurwa nemvura inobva pasi kuenda kumusoro, vharuvhu ine chimiro chakareruka, clamp inoiswa pakati pemaflange maviri, uye saizi diki nehuremu hwakareruka zvakaderera.

Iyovharuvhu yekutarisa ndiro mbiri yewaferine madhisiki maviri akaita seD akaiswa pachitubu akaiswa pagomba rakamonera paburi revharuvhu. Chimiro ichi chinopfupisa daro rinofambiswa nepakati pedhisiki. Kugadzirwa uku kunoderedzawo huremu hwedhisiki ne50% zvichienzaniswa nevharuvhu yekutarisa inotenderera nedhisiki imwe chete ine saizi imwe chete. Nekuda kwemutoro wechitubu, vharuvhu inokurumidza kupindura nekudzokera shure.

　　Kugadzirwa kwevharuvhu yekutarisa maplate maviri ewafer kunoita kuti kuvhara zvigaro uye kushanda kwacho kuve nyore.

　　Kushanda kwechitubu cheruoko rurefu cheshavishavi rakapetwa kavirivharuvhu yekutarisainobvumira dhisiki kuvhura nekuvharika pasina kukwiza chigaro, uye chitubu chinoshanda chega kuvhara dhisiki (DN150 zvichikwira).

　　Chibato cheshavishavi rine mahinji chinotsigirwa neshavishavi rine mapini mavirivharuvhu yekutarisainoderedza kukweshana uye inoderedza mvura inoyerera kana ikabviswa nedhisiki yakasiyana (bore hombe).

Zvichienzaniswa nezvakajairikamavharuvhu ekuongorora swing,vharuvhu yekutarisa ndiro mbiri yewaferKuvaka kwacho kunowanzova kwakasimba, kwakareruka, kudiki, kunoshanda zvakanyanya, uye kusingadhuri zvakanyanya. Vharuvhu iyi inosangana nechiyero cheAPI 594, kune akawanda madhayamita, saizi yevharuvhu iyi inongova 1/4 yevharuvhu yakajairika, uye huremu hwayo i15% ~ 20% yevharuvhu yakajairika, saka yakachipawo pane vharuvhu yekutarisa swing. Zvakare zviri nyore kuisa pakati pemagaskets akajairwa nemapipe flanges. Nekuti iri nyore kubata uye inoda seti imwe chete yemabhoti ekubatanidza flange, inochengetedzawo zvikamu panguva yekuisa, ichichengetedza mari yekuisa uye mari yekugadzirisa yezuva nezuva.

Vharuvhu yekutarisa butterfly ine double-flap inewo magadzirirwo akakosha anoita kuti vharuvhu iyi ive vharuvhu yekutarisa isingakanganisike inoshanda zvakanyanya. Magadzirirwo aya anosanganisira kuvhura kusina kuchena, kugadzirwa kwechitubu kwakazvimirira kwemavharuvhu mazhinji ebore, uye masisitimu ekutsigira madhisiki akazvimirira. Mamwe emagadzirirwo aya haawanikwe nemavharuvhu ekutarisa. Vharuvhu yekutarisa mawafer maviri inogonawo kugadzirwa nemalugs, double flanges uye muviri wakarebeswa.

Chekutanga, maitiro ekuvhura nekuvhara

Kugadzirwa kwemadhisiki maviri aya kune madhisiki maviri ane maspring-loaded (semi-discs) akasungirirwa papini ine hinged iri pakati. Kana mvura yacho yatanga kuyerera, dhisiki rinovhurwa nesimba rinobuda (F) richishanda pakati pesealing surface. Simba rekutsigira spring rinoshanda (FS) rinoshandiswa panzvimbo iri kunze kwepakati pe disc face, zvichiita kuti mudzi wedhisiki uvhurike kutanga. Izvi zvinodzivirira kukweshana pamusoro pesealing surface kunoitika kana dhisiki ikavhurwa mumavalvu ekare, zvichibvisa kupera simba pazvikamu.

Kana mwero wekuyerera kwemvura waderera, chitubu chetorsion chinozvipindura chega, zvichiita kuti dhisiki ivharwe yoswedera pedyo nechigaro chemuviri, zvichideredza daro rekufamba nenguva yekuvharwa. Kana mvura yacho yayerera ichidzokera kumashure, dhisiki yacho inoswedera pedyo nechigaro chemuviri zvishoma nezvishoma, uye mhinduro yevharuvhu inokurumidziswa zvikuru, zvichideredza simba remvura uye zvichiita kuti ishande zvakanaka.

Pakuvhara, chiito che spring force action point chinoita kuti pamusoro pe disc pavharwe kutanga, zvichidzivirira kuruma nekukweshana pamudzi we disc, kuitira kuti vharuvhu igone kuchengetedza kuvimbika kwechisimbiso kwenguva yakareba.

Kugadzirwa kwechitubu (DN150 zvichikwira) kunoita kuti torque yakakura ishandiswe padhisiki rega rega uye dhisiki rinovhara roga sezvo kufamba kwemaindasitiri kuchichinja. Kuedza kwakaratidza kuti izvi zvakaita kuti hupenyu hwevharuvhu huwedzere ne25% uye kudzikira kwehammer yemvura ne50%.

Chikamu chimwe nechimwe chedhisiki mbiri chine matsime aro anopa simba rekuvhara rakazvimirira uye anoiswa pakona diki ye140° (mufananidzo 3) pachinzvimbo che350° yechitubu chetsika chine mabhureki maviri.

3. Chimiro chekumiswa kwedhisiki yakazvimirira

Chimiro chehingi yakazvimirira chinoderedza kukweshana ne66%, izvo zvinovandudza zvikuru reactivity yevharuvhu. Chishongo chekutsigira chinoiswa kubva pahingi yekunze kuitira kuti hingi yepamusoro igone kutsigirwa yakazvimirira nehingi yepasi panguva yekushanda kwevharuvhu. Izvi zvinobvumira madhisiki ese maviri kuti aite nekukurumidza uye avhare panguva imwe chete, zvichiita kuti pave nekushanda kwakanaka kwazvo.
