I-24KW Electric Steam Generator yezicindezelo ze-Iron

2. Ukuhlukaniswa kanye nezici zama-valve okuhlola angenisiwe
I-valve yokuhlola:
1. Ngokusho kwesakhiwo, ingahlukaniswa ngezinhlobo ezintathu: i-valve yokuhlola isheke, i-valve yokuhlola i-swing kanye ne-butterfly check valve.
①I-valve yokuhlola i-Lift ingahlukaniswa ngezinhlobo ezimbili: iqonde futhi ivundlile.
②Ama-valve okuhlola ama-Swing ahlukaniswe abe izinhlobo ezintathu: i-flap eyodwa, i-flap ephindwe kabili kanye ne-flap eminingi.
③Ivalve yokuhlola uvemvane iwuhlobo oluqondile.
Amafomu okuxhumana ama-valve okuhlola angenhla angahlukaniswa abe yizinhlobo ezintathu: uxhumano lwentambo, uxhumano lwe-flange kanye ne-welding.
Ngokuvamile, amavalvu okuhlola ukuphakamisa aqondile (ububanzi obuncane) asetshenziswa kumapayipi avundlile anobubanzi obungu-50mm. Ivalvu yokuhlola i-lift eqondile ingafakwa kuwo womabili amapayipi avundlile naqondile. Ivalvu engezansi ivamise ukufakwa kuphela epayipini elime mpo le-pump inlet, kanti ephakathi igeleza ukusuka phansi ukuya phezulu. Ama-valve okuhlola okuphakamisa asetshenziswa lapho ukuvala ngokushesha kuyadingeka.
I-valve yokuhlola i-swing ingenziwa ibe yingcindezi yokusebenza ephezulu kakhulu, i-PN ingafinyelela ku-42MPa, futhi i-DN nayo ingenziwa ibe nkulu kakhulu, enkulu kunazo zonke ingafinyelela ngaphezu kwe-2000mm. Kuye ngezinto zegobolondo kanye nophawu, ingasetshenziswa kunoma iyiphi indawo yokusebenza nanoma yiluphi uhla lokushisa olusebenzayo. Okuphakathi kwamanzi, umusi, igesi, indawo edlayo, uwoyela, ukudla, umuthi, njll. Izinga lokushisa eliphakathi nendawo elisebenzayo liphakathi kuka -196~800℃. Isikhathi esisebenzayo sokuhlola uvemvane ukucindezela okuphansi nobubanzi obukhulu.
3. Ukukhethwa kwe-valve yokuhlola umusi kufanele kuhlangabezane nezidingo ezilandelayo
1. Ingcindezi ngokuvamile kufanele ikwazi ukumelana ne-PN16 noma ngaphezulu
2. Izinto ezisetshenziswayo ngokuvamile ziyinsimbi eyinsimbi nensimbi engagqwali, noma insimbi ye-chrome-molybdenum. Akufanelekile ukusebenzisa i-cast iron noma ithusi. Ungakhetha ama-valve okuhlola insimbi ye-steam cast kanye nama-valve okuhlola insimbi engenasici engenisiwe.
3. Ukumelana nokushisa kufanele kube okungenani ama-degree angu-180. Ngokuvamile, ama-valve okuhlola avalwe ngokuthambile awakwazi ukusetshenziswa. Amavalvu okuhlola ukujika kwesitimu angenisiwe noma amavalufu okuhlola ama-steam lift angakhethwa, bese kusetshenziswa izigxivizo eziqinile zensimbi engagqwali.
4. Indlela yokuxhuma ngokuvamile isebenzisa uxhumano lwe-flange
5. Ifomu lesakhiwo ngokuvamile lithatha uhlobo lokushwiba noma uhlobo lokuphakamisa.
