Ii-valve yokuhlola ipuleti eliphindwe kabili le-waferfuthi uhlobo lwevalvu yokuhlola ene-actuation ejikelezayo, kodwa iyidiski ephindwe kabili futhi ivala ngaphansi kwesenzo sesipilingi. Idiski icindezelwa ivuleke ngoketshezi oluvela phansi kuya phezulu, ivalvu inesakhiwo esilula, i-clamp ifakwa phakathi kwama-flange amabili, kanti usayizi omncane nesisindo esincane kuphansi.
Ii-valve yokuhlola ipuleti eliphindwe kabili le-waferinamadiski amabili afakwe esiphethwini anomumo we-D abekwe ku-shaft enemicu ngaphesheya kwe-valve bore. Lesi sakhiwo sifinyeza ibanga elihanjiswa yisikhungo samandla adonsela phansi sediski. Lokhu kwakhiwa kunciphisa nesisindo sediski ngo-50% uma kuqhathaniswa ne-valve yokuhlola i-swing-on yediski eyodwa enobukhulu obufanayo. Ngenxa yomthwalo wesiphethwini, ivalve isabela ngokushesha kakhulu ekugelezeni emuva.
Ukwakhiwa kwevalvu yokuhlola amapuleti amabili e-wafer elula ene-lobe ephindwe kabili kwenza ukuvala izihlalo nokusebenza kwazo kube ngcono kakhulu.
Isenzo sentwasahlobo esinengalo ende sebhabhathane eliphindwe kabiliivalvu yokuhlolaivumela idiski ukuthi ivuleke futhi ivale ngaphandle kokuhlikihla isihlalo, kanti isipilingi sisebenza ngokuzimela ukuvala idiski (DN150 nangaphezulu).
Isivikelo esisekelayo esinama-hinged sevemvane eliphindwe kabiliivalvu yokuhlolakunciphisa ukungqubuzana futhi kunciphisa isando samanzi uma sikhishwa ngediski ehlukile (imbobo enkulu).
Uma kuqhathaniswa nokuvamileamavalvu okuhlola ukujika,i-valve yokuhlola ipuleti eliphindwe kabili le-waferUkwakhiwa ngokuvamile kuqinile, kulula, kuncane, kusebenza kahle, futhi kungabizi kakhulu. Le valve ihlangabezana nezindinganiso ze-API 594, kuma-diameter amaningi, usayizi wobuso nobuso wale valve uyi-1/4 kuphela yevalvu evamile, futhi isisindo singu-15% ~ 20% yevalvu evamile, ngakho-ke ishibhile futhi kunevalvu yokuhlola i-swing. Kulula futhi ukuyifaka phakathi kwama-gasket ajwayelekile nama-flange epayipi. Ngenxa yokuthi kulula ukuyiphatha futhi idinga isethi eyodwa kuphela yama-bolts okuxhuma i-flange, igcina nezingxenye ngesikhathi sokufakwa, igcina izindleko zokufaka kanye nezindleko zokulungisa zansuku zonke.
Ivalvu yokuhlola i-butterfly enama-flap amabili nayo inezici ezikhethekile zokwakha ezenza le valve ibe yivalvu yokuhlola engasebenzi kahle. Lezi zici zifaka phakathi ukuvulwa okungahlanzekile, ukwakhiwa kwentwasahlobo okuzimele kwamavalvu amaningi e-bore, kanye nezinhlelo zokusekela amadiski ezizimele. Ezinye zalezi zici azitholakali ngamavalvu okuhlola. Ivalvu yokuhlola i-wafer dual plate ingaklanywa ngama-lugs, ama-flange amabili kanye nomzimba onwetshiwe.
Okokuqala, inqubo yokuvula nokuvala
Ukwakhiwa kwamadiski amabili kunamadiski amabili alayishwe ngesiphethu (ama-semi-disc) alengiswe ephinini eligobile eliqonde phakathi nendawo. Lapho uketshezi luqala ukugeleza, idiski ivuleka ngamandla aphumela (F) asebenza phakathi nendawo yokuvala. Amandla okusekela isiphethu aphikisayo (FS) asetshenziswa endaweni engaphandle kwendawo yokuvala idiski, okwenza impande yediski ivuleke kuqala. Lokhu kugwema ukungqubuzana endaweni yokuvala okwenzeka lapho idiski ivulwa kumavalvu amadala avamile, kususa ukuguguleka kwezingxenye.
Uma izinga lokugeleza lehla, intwasahlobo yokugoba iphendula ngokuzenzakalelayo, okubangela ukuthi idiski ivale futhi isondele esihlalweni somzimba, kunciphisa ibanga lokuhamba nesikhathi sokuvala. Lapho uketshezi lugeleza emuva, idiski isondela kancane kancane esihlalweni somzimba, futhi impendulo enamandla yevalvu ishesha kakhulu, kunciphisa umphumela wesando samanzi futhi kufezwe ukusebenza okungenamthelelo.
Lapho kuvalwa, isenzo sendawo yesenzo samandla entwasahlobo sibangela ukuthi ingxenye ephezulu yediski ivalwe kuqala, okuvimbela ukuluma nokungqubuzana empandeni yediski, ukuze ivalvu ikwazi ukugcina ubuqotho besivalo isikhathi eside.
2. Isakhiwo sentwasahlobo esizimele
Ukwakhiwa kwentwasahlobo (DN150 nangaphezulu) kuvumela ukuthi kufakwe i-torque enkulu kudiski ngayinye futhi idiski ivala ngokuzimela njengoba ukugeleza kwezimboni kushintsha. Ukuhlolwa kubonise ukuthi lo mphumela uholele ekukhuleni okungu-25% empilweni yamavalvu kanye nokwehla okungu-50% kwesando samanzi.
Ingxenye ngayinye yediski ephindwe kabili inezipilingi zayo ezihlinzeka ngamandla okuvala azimele futhi zibhekene ne-angle offset encane kakhulu engu-140° (umfanekiso 3) esikhundleni se-350° yesipilingi esivamile esinamabakaki amabili.
3. Isakhiwo sokumiswa kwediski esizimele
Isakhiwo sehinge esizimele sinciphisa ukungqubuzana ngo-66%, okuthuthukisa kakhulu ukusebenza kwevalvu. Isivikelo sokusekela sifakwa kusuka kuhinge engaphandle ukuze ihinge engenhla ikwazi ukusekelwa ngokuzimela yihinge engezansi ngesikhathi sokusebenza kwevalvu. Lokhu kuvumela amadiski womabili ukuthi asabele ngokushesha futhi avaleke ngesikhathi esifanayo, kufezwe ukusebenza okuhle kakhulu okuguquguqukayo.
Okwesine, imodi yokuxhumanisa nepayipi
Ama-valve okuhlola amapuleti amabili e-Waferfuthi amapayipi angaxhunywa ngezibambo, ama-lugs, ama-flange, kanye nezibambo.
