Cheki mavharuvhu mavharuvhu otomatiki anovhura nekuyerera kwemberi uye anovhara nereverse kuyerera.
Kudzvinyirirwa kwemvura inopfuura nepakati pegadziriro inovhura vharuvhu, nepo chero kudzoka kwekuyerera kunovhara valve.Kushanda chaiko kuchasiyana zvichienderana nerudzi rweCheck valve mechanism.Mhando dzakawanda dzeCheck mavharuvhu ndeyekuzunguza, kusimudza (piston uye bhora), shavishavi, mira uye tilting-dhisiki.
Pano mugadziri weRXVAL anosuma zvakasiyana pakati peSwing Check Valve uye Lift Check Valve.
Swing Check Valve
A basic swing Check valve ine muviri wevharuvhu, bhoneti, uye dhisiki rakabatana kune hinge.Iyo dhisiki inozununguka kubva pavharuvhu-seat kubvumira kuyerera munzira yekumberi, uye inodzokera kuvharuvhu-seat kana kumusoro kwerwizi kuyerera kunomiswa, kudzivirira kumashure-kuyerera.
Iyo dhisiki iri mumhando yekuzunguza Tarisa vharafu haina kutariswa sezvainovhura zvizere kana kuvhara.Kune akawanda dhisiki uye magadzirirwo ezvigaro aripo, kuitira kuti asangane nezvinodiwa zvezvikumbiro zvakasiyana.Ivhavha inobvumira kuyerera kuzere, kusina kuvharwa uye inovhara pakarepo sezvo kudzvinyirira kunoderera.Aya mavharuvhu akavharwa zvakazara kana kuyerera kwasvika zero, kuitira kudzivirira kumashure-kuyerera.Turbulence uye kudonha kwekumanikidza muvharuvhu kwakadzikira.
Swing cheki vharafu, swing tarisa vharuvhu kuchigaro chevhavhavha yakatenderedza chiteshi chevhavha yekutenderera, nekuti chiteshi chevhavha ichienda kune yakanyoroveswa, inoyerera inomira kupfuura iyo diki yevhavha inosimudza cheki, yakakodzera kune yakakura caliber nguva mukuyerera kwakaderera uye hapana kuyerera kunowanzo chinja. , asi haifanirwe kushandiswa pakupuruzira kuyerera, iyo yekuisa chisimbiso ishoma pane kusimudza.
Simudza Check Valve
Dhizaini yechigaro chekusimudzira-Cheki vharafu yakafanana neGlobe valve.Iyo disc kazhinji iri muchimiro chepiston kana bhora.
Lift Check mavharuvhu anonyanya kukodzera basa repamusoro-soro apo velocity yekuyerera yakakwirira.Mukusimudza Tarisa mavharuvhu, dhisiki rinonyatsotungamirwa uye rinokwana zvakakwana mudhishibhoti.Lift Check mavharuvhu akakodzera kuisirwa mune yakachinjika kana yakatwasuka pombi-mitsetse inoyerera inokwira.
Kuyerera kusimudza Tarisa mavharuvhu anofanira kugara achipinda pazasi pechigaro.Sezvo kuyerera kunopinda, piston kana bhora rinosimudzwa mukati mevatungamiri kubva pachigaro nekumanikidzwa kwekuyerera kwepamusoro.Kana kuyerera kwamira kana kudzoka shure, piston kana bhora rinomanikidzwa pachigaro chevharuvhu nezvose zviri shure uye giravhiti.
Iyo dhisiki inogona kushandiswa mune yakanyanya kudzvinyirira diki bore cheki valve.Muviri wevhavha yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha yekuchekwa (iyo inogona kushandiswa nevhavha yekumisa),saka ine coefficient yakakura yefluid resistance.Chimiro chakafanana nevhavha yakachekwa, muviri wevhavha uye disc zvakafanana nevhavha yakachekwa.Chikamu chezasi chevharuvhu yepamusoro uye chivharo chevhavha chivharo chekugadzira chigadziro chegwaro, vharafu iri muvharuvhu inosimudza yemahara gidhi nyore nyore inotyairwa, kana yepakati yakadzika, iyo vharafu yakavhurika nevezvenhau, apo midhiya yakamira kuyerera, vharafu iyo self vertical kumhara pachigaro, kudzivirira midhiya kubva kumusoro kwemvura.
Yakatwasuka yekusimudza cheki vharafu, kutungamira kwekupinda nekubuda kwepakati kune perpendicular kune kutungamira kwechigaro chevharuvhu.
Iyo vertical lift cheki valve ine kutungamira kwakafanana nechigaro chevharuvhu uye kutungamira kweinopinza uye kubuda kwevhavha, uye kuyerera kwekudzivirira kudiki pane iyo yakatwasuka kuburikidza nevhavha.
