Iwafer emapuleti lamabili ekuhlola ivalvuiphindze ibe luhlobo lwevalve yekuhlola lene-actuation lejikeletako, kepha iyi-disc lephindvwe kabili futsi ivala ngaphansi kwesento sentfwasahlobo. Le disc iphushelwa ivuleke ngumtfunti losuka phansi uya etulu, le valve inesakhiwo lesilula, le clamp ifakwa emkhatsini wema flanges lamabili, futsi bukhulu lobuncane kanye nesisindvo lesilula kuphansi.
Iwafer emapuleti lamabili ekuhlola ivalvuinema-disc lamabili lalayishwa intfwasanhlobo lamise ngendlela ye-D labekwe kushafti lenetimbambo ngaphesheya kwemgodzi wevalve. Lesi sakhiwo sifinyeta ibanga kutsi sikhungo gravity disc uhamba. Lokwakhiwa kuphindze kunciphise sisindvo se-disc nga-50% uma kucatsaniswa ne-valve yekuhlola le-swing-on ye-disc yinye lelinganako. Ngenca umthwalo intfwasanhlobo, valve isabela ngekushesha kakhulu backflow.
I-wafer dual plate check valve yekwakhiwa lokulula lokune-lobe lephindvwe kabili kwenta kuvalwa kwesihlalo kanye nekusebenta kusebente kahle kakhulu.
Sento sentfwasahlobo lesinemkhono lomudze seluvivane loluphindvwe kabilihlola ivalvuivumela le disc kutsi ivuleke futsi ivale ngaphandle kwekuhlikihla situlo, futsi intfwasanhlobo isebenta ngekutimela kuvala le disc (DN150 nangaphezulu).
Umkhono wekusekela lonetinsimbi weluvivane loluphindvwe kabilihlola ivalvukunciphisa kukhuhlana futsi kunciphisa isando semanti uma kukhishwa nge disc lehlukile (imbobo lenkhulu).
Nawucatsanisa nendlela levamileemavalvu ekuhlola lajikeletako,wafer emapuleti lamabili ekuhlola ivalvukwakha kuvame kuba nemandla, kulula, kuncane, kusebenta kahle, futsi akubiti kakhulu. Le valve ihlangabetana nelizinga le API 594, kuma diameters lamanyenti, bukhulu bebuso nebuso bale valve bungu 1/4 kuphela we valve levamile, futsi sisindvo ngu 15% ~ 20% we valve levamile, ngako-ke iphindze ishiphe kune valve yekuhlola yekujika. Kuphindze kube lula kufaka emkhatsini gaskets ejwayelekile kanye flanges emapayipi. Ngenca yekutsi kulula kuphatsa futsi kudzinga isethi yinye kuphela yemabhawudi ekuhlanganisa e-flange, kuphindze kugcine tincenye ngesikhatsi sekufakwa, kugcine tindleko tekufaka kanye netindleko tekunakekelwa nsuku zonke.
Le valve yekuhlola le-double-flap butterfly iphindze ibe netintfo letikhetsekile tekwakha letenta levalve ibe yivalve yekuhlola lesetulu lengaphatseki. Letici tifaka ekhatsi kuvulwa lokungekho-kuhlanteka, kwakhiwa kwentfwasanhlobo lokutimele kwemavalvu lamaningi ekubopha, kanye netinhlelo tekusekela ema-disc letitimele. Letinye taletintfo atitfolakali ngemavalvu ekuhlola. I valve yekuhlola ipuleti le-wafer lembili ingaphindze yakhelwe nge-lugs, ema-flanges lamabili kanye nemtimba loweluliwe.
Kwekucala, inchubo yekuvula nekuvala .
Lokwakhiwa kwema-disc lamabili kufaka ema-disc lamabili lalayishwa ngetintfwasahlobo (ema-semi-disc) lalengiswe ku-pin le-hinged lemile emkhatsini. Uma loludzaka lucala kugeleta, le disc ivuleka ngemandla laphumelelako (F) lasebenta emkhatsini wendzawo yekuvala. Emandla ekusekela entfwasahlobo laphikisako (FS) asetjentiswa endzaweni lengaphandle kwesikhungo sebuso be disc, kwenta kutsi umsuka we disc uvuleke kucala. Loku kugwema kukhuhlana endzaweni yekuvala leyenteka uma le disc ivulwa kumavalvu lamadzala lavamile, kucedza kugcoka kanye nekudzabuka etincenyeni.
Uma lizinga lekugeleta lincipha, intfwasanhlobo yekugucuka iyatentela, kwenta kutsi le disc ivale bese isondzela esihlalweni semtimba, kunciphisa libanga lekuhamba kanye nesikhatsi sekuvala. Uma loludzaka lugeleta emuva, le disc kancane kancane isondzela esihlalweni semtimba, bese kuphendvula lokushintjashintjako kwe valve kusheshiswa kakhulu, kunciphisa umphumela wesando semanti futsi kuzuze kusebenta lokute umtselela.
Uma kuvalwa, sento sendzawo yesento semandla entfwasanhlobo senta kutsi phezulu kwe disc kuvalwe kucala, kuvikela kuluma kanye nekukhuhlana empandeni ye disc, kwentela kutsi le valve ingagcina bucotfo bekuvala sikhatsi lesidze.
2. Isakhiwo sentfwasahlobo letimele
Lokwakhiwa kwentfwasanhlobo (DN150 kuya etulu) kuvumela kutsi kusetjentiswe i-torque lenkhulu ku-disc ngayinye bese le-disc ivala ngekutimela njengoba kugeleta kwetimboni kushintja. Kuhlola kukhombise kutsi lomphumela uholele ekukhuleni kwemphilo ye valve nga 25% kanye nekuncipha nga 50% kwesando semanti.
Sigaba ngasinye se disc lephindvwe kabili sinetitfombo tayo letiniketa emandla ekuvala latimele futsi tibekwa ngaphansi kwekugucuka lokuncane kwe angular kwa 140° (fig. 3) esikhundleni se 350° yetitfombo letivamile letinebakaki lababili.
3. Isakhiwo sekumiswa kwediski lesizimele
Lesakhiwo se-hinge lesitimele sinciphisa kukhuhlana nga-66%, lokutfutfukisa kakhulu kusebenta kwevalve. Le sleeve yekusekela ifakwa kusuka ku hinge lengaphandle kute kutsi le hinge lengetulu ingasekelwa ngekutimela ngumkhono longephansi ngesikhatsi sekusebenta kwe valve. Loku kuvumela womabili lama-disc kutsi asabele ngekushesha futsi avalwe ngesikhatsi sinye, azuze kusebenta lokuhle kakhulu lokushintjashintjako.
Kwesine, imodi yekuxhumana nephayiphi .
Emavalvu ekuhlola emapuleti lamabili e-Waferfutsi emaphayiphi angahlanganiswa ngema-clamp, ema-lugs, ema-flanges, kanye nema-clamp.
