I-valve yokuhlola ibhekisela ku-valve evula futhi ivale ngokuzenzakalelayo i-valve disc kuye ngokugeleza kwe-medium ngokwayo ukuvimbela ukugeleza emuva kwe-medium.Yaziwa nangokuthi i-valve yokuhlola, i-valve yendlela eyodwa, i-valve yokugeleza ehlehlayo kanye ne-back pressure valve.I-valve yokuhlola ingeye-automatic valve.Umsebenzi wayo oyinhloko ukuvimbela ukubuyela emuva kwe-medium, ukuzungeza okuphambene kwepompo kanye nemoto yokushayela, kanye nokukhishwa kwe-container medium.
Isimiso sokusebenza se-valve yokuhlola
1. Ukuze kuvinjwe ukugeleza okubuyela emuva kwe-medium, ama-valve okuhlola kufanele afakwe ezintweni ezisetshenziswayo, kumishini kanye namapayipi;
2. Ama-valve okuhlola ngokuvamile afanelekela imidiya ehlanzekile, hhayi imidiya equkethe izinhlayiya eziqinile kanye ne-viscosity ephezulu;
3. Ngokuvamile, ivalvu yokuhlola yokuphakamisa evundlile kufanele ikhethwe epayipini elivundlile elinobubanzi obungu-50mm;
4. Ngokuqondile ngokuphakamisa i-valve yokuhlola ingafakwa kuphela epayipini elivundlile;
5. Ngepayipi lokungena lepompo, i-valve engezansi kufanele ikhethwe.Ngokuvamile, i-valve engezansi ifakwa kuphela epayipini elime mpo endaweni yokungena yepompo, futhi okuphakathi kugeleza ukusuka phansi kuye phezulu;
6. Uhlobo oluphakamisayo lunomsebenzi ongcono wokuvala kanye nokumelana noketshezi olukhulu kunohlobo lokushwibeka.Uhlobo oluvundlile kufanele lufakwe epayipini elivundlile kanye nohlobo olume mpo epayipini elime mpo;
7. Isikhundla sokufakwa kwe-valve yokuhlola i-swing ayinqunyelwe.Ingafakwa kumapayipi avundlile, aqondile noma athambekele.Uma ifakwe kumapayipi aqondile, isiqondiso sokugeleza okuphakathi kufanele sisuke phansi siye phezulu;
8. I-valve yokuhlola i-swing akufanele yenziwe ibe i-valve enobubanzi obuncane, kodwa ingenziwa ibe yingcindezi yokusebenza ephezulu kakhulu.Ukucindezela okuzisholo kungafinyelela ku-42MPa, futhi ububanzi obujwayelekile bungaba bukhulu kakhulu, obungafinyelela ngaphezu kuka-2000mm.Ngokwezinto ezihlukene zegobolondo kanye ne-seal, ingasebenza kunoma iyiphi indawo yokusebenza nanoma yiluphi uhla lokushisa olusebenzayo.I-medium ngamanzi, umusi, igesi, i-corrosion medium, uwoyela, umuthi, njll. Izinga lokushisa elisebenzayo le-medium ngu-196-800 ℃;
9. I-valve yokuhlola i-Swing ifanele ukucindezela okuphansi nobubanzi obukhulu, futhi isikhathi sokufaka sinqunyelwe;
10. Indawo yokufaka i-valve yokuhlola uvemvane ayinqunyelwe.Ingafakwa epayipini elivundlile noma ipayipi eliqondile noma elithambekele;
Isimiso sesakhiwo se-valve yokuhlola
Lapho i-valve yokuhlola i-swing ivuliwe ngokugcwele, umfutho we-fluid cishe awuphazamiseki, ngakho-ke ukwehla kwengcindezi nge-valve kuncane kakhulu.Isihlalo se-valve yokuhlola i-lift sitholakala endaweni yokuvala yomzimba we-valve.Ngaphandle kokuthi i-disc ye-valve ingakhuphuka futhi iwe ngokukhululekile, yonke i-valve ifana ne-valve yokumisa.Umfutho we-fluid uphakamisa i-disc ye-valve endaweni yokuvala yesihlalo se-valve, futhi ukugeleza kwe-backflow okuphakathi kubangela ukuthi i-disc ye-valve ibuyele esihlalweni se-valve futhi inqamule ukugeleza.Ngokwemibandela yesevisi, idiski ye-valve ingaba yazo zonke izakhiwo zensimbi noma ifakwe ngephedi yerabha noma indandatho yerabha kuhlaka lwediski ye-valve.Njenge-valve yokumisa, ukudlula koketshezi nge-valve yokuhlola i-lift nakho kuncane, ngakho-ke ukwehla kwengcindezi nge-valve yokuhlola i-lift kukhulu kunaleyo ye-valve yokuhlola i-swing, futhi ukugeleza kwe-valve yokuhlola i-swing akuvamile ukukhawulelwa.
I-1, i-Swing check valve: i-disc ye-valve yokuhlola i-swing isesimweni se-disc futhi izungeza i-shaft ejikelezayo yesiteshi sesihlalo se-valve.Ngenxa yokuthi isiteshi esiku-valve silungiswa futhi ukumelana nokugeleza kuncane kune-valve yokuhlola i-lift, ifanele izikhathi zobubanzi obukhulu ngezinga eliphansi lokugeleza nokushintsha kokugeleza okungajwayelekile, kodwa ayifanele ukugeleza kwe-pulsating, futhi ukusebenza kokuvala akukuhle njengalokho kwevalve yokuhlola i-lift.I-valve yokuhlola i-Swing ihlukaniswe yaba uhlobo olulodwa lwe-disc, uhlobo lwe-disc oluphindwe kabili kanye nohlobo lwe-multi half.Lezi zinhlobo ezintathu zihlukaniswa ngokuyinhloko ngokobubanzi be-valve, ukuze kuvinjwe umthelela we-hydraulic ekubeni buthakathaka lapho okuphakathi kuma ukugeleza noma ukugeleza emuva.
2, Phakamisa i-valve yokuhlola: i-valve yokuhlola i-valve yayo eyidiski islayida eduze komugqa ophakathi nendawo womzimba we-valve.Ivalvu yokuhlola i-lift ingafakwa kuphela epayipini elivundlile.Ku-valve yokuhlola enobubanzi obuncane yokucindezela okuphezulu, i-valve disc ingathatha ibhola.Ukuma komzimba we-valve yokuhlola i-lift kuyafana ne-valve yokumisa (engasetshenziswa ne-valve yokumisa), ngakho-ke i-coefficient yayo yokumelana noketshezi inkulu.Ukwakheka kwayo kufana ne-valve yokumisa, futhi umzimba we-valve ne-disc kufana ne-valve yokumisa.Ingxenye engenhla yediski ye-valve kanye nengxenye engezansi yesembozo se-valve icutshungulwa ngomkhono womhlahlandlela.Umkhono womhlahlandlela wediski ye-valve ungakhuphuka futhi wehle ngokukhululekile kumkhono wekhephu yevalvu.Lapho i-medium igeleza yehla nomfula, i-valve disc ivuleka ngokuphonswa kwe-medium.Lapho okuphakathi kuyeka ukugeleza, i-valve disc iwela esihlalweni sevalvu iqonde ukuvimbela ukugeleza okubuyela emuva kwe-medium.Isiqondiso se-medium inlet kanye neshaneli yokuphuma ye-valve yokuhlola iqonde ngokuphakamisa i-perpendicular kusiqondiso sesiteshi sesihlalo se-valve;Isiqondiso sesiteshi sokungena esiphakathi nendawo sokuphuma se-valve yokuhlola ephakamisayo siyafana nesesiteshini sesihlalo se-valve, futhi ukumelana nokugeleza kwayo kuncane kunokwe-valve yokuhlola eqondile.
3, Ivalve yokuhlola uvemvane: ivalve yokuhlola idiski yayo ezungeza iphinikhodi esihlalweni.Ivalvu yokuhlola idiski inesakhiwo esilula futhi ingafakwa kuphela epayipini elivundlile elingasebenzi kahle ngokuvala.
4, I-valve yokuhlola ipayipi: ivalvu idiski yayo islayida emgqeni omaphakathi womzimba wevalvu.I-valve yokuhlola ipayipi iyivalvu entsha.Inomthamo omncane, isisindo esincane kanye nobuchwepheshe obuhle bokucubungula.Ingenye yezinkomba zokuthuthukiswa kwe-valve yokuhlola.Kodwa-ke, i-coefficient yokumelana noketshezi inkulu kancane kune-valve yokuhlola i-swing.
5, Ivalve yokuhlola ukucindezela: Le valve isetshenziswa njengamanzi okuphakelayo kubhayela kanye nevalve yokuvala isitimu.Inomsebenzi obanzi wokuphakamisa i-valve yokuhlola, i-valve yokumisa noma i-engeli valve.
Ngaphezu kwalokho, kukhona ama-valve okuhlola angafanelekile ukufakwa kwe-pump outlet, njenge-valve engezansi, uhlobo lwentwasahlobo, uhlobo lwe-Y, njll.
