I-valve yokuhlola: I-valve yokuhlola, eyaziwa nangokuthi i-valve yendlela eyodwa noma i-valve yokuhlola, isetshenziselwa ukuvimbela okuphakathi epayipini ukuthi libuyele emuva.Ivalvu engezansi yokudonsa nokuvala kwepompo yamanzi nayo ingeyesigaba sevalvu yokuhlola.Ivalvu ethembele ekugelezeni nasekuphoqeni okuphakathi ukuthi izivule noma izivale, ukuze kuvinjwe i-medium ukuthi ingabuyeli emuva, ibizwa ngokuthi i-check valve.Ama-valve okuhlola ayingxenye yama-automatic valves.Amavalvu okuhlola asetshenziswa kakhulu kumapayipi anokugeleza okukodwa kwemidiya, okuvumela inkomba eyodwa kuphela yokugeleza kwemidiya ukuvimbela izingozi.Ama-valve okuhlola angahlukaniswa abe izinhlobo ezintathu ngokuya ngesakhiwo sawo: ama-valve okuhlola okuphakamisa, ama-valve okuhlola ama-swing, nama-valve okuhlola uvemvane.Ama-valve okuhlola ama-Lift angahlukaniswa abe izinhlobo ezimbili: ama-valve okuhlola aqondile kanye nama-valve okuhlola avundlile.Ama-valve okuhlola ama-Swing ahlukaniswe abe izinhlobo ezintathu: ama-valve okuhlola ama-disc eyodwa, ama-valve okuhlola ama-disc amabili, nama-valve okuhlola amadiski amaningi.Ama-valve okuhlola uvemvane aqondile ngokusebenzisa ama-valve okuhlola, futhi izinhlobo ezingenhla zamavalvu okuhlola zingahlukaniswa zibe izinhlobo ezintathu ngokuxhunywa: ama-valve okuhlola anemicu, ama-valve okuhlola ama-flange, nama-valve okuhlola ashiselwe.
Ukufakwa kwama-valve okuhlola kufanele kunake lezi zinto ezilandelayo:
1. Ungavumeli i-valve yokuhlola ukuthi ithwale isisindo epayipini.Ama-valve amakhulu okuhlola kufanele asekelwe ngokuzimela ukuze avinjwe ukuthi angaphazanyiswa ukucindezela okukhiqizwa uhlelo lwamapayipi.
2. Ngesikhathi sokufakwa, naka isiqondiso sokugeleza okuphakathi okufanele kuhambisane nesiqondiso somcibisholo okhonjiswe emzimbeni we-valve.
3. Amavalvu okuhlola amadiski amile kufanele afakwe kumapayipi aqondile.
4. Ivalvu yokuhlola idiski evundlile yohlobo lokuphakamisa kufanele ifakwe epayipini elivundlile.
Imingcele yokusebenza eyinhloko yama-valve okuhlola:
Ingcindezi yokulinganisa noma izinga lokucindezela: PN1.0-16.0MPa, ANSI Class150-900, JIS 10-20K, ububanzi bokulinganisa noma ububanzi: DN15~900, NPS 1/4-36, indlela yokuxhuma: i-flange, i-butt welding, intambo, isokhethi i-welding, njll., izinga lokushisa elisebenzayo: -196 ℃~540 ℃, i-valve body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti.Ngokukhetha izinto ezihlukene, i-valve yokuhlola ingafaneleka emithonjeni ehlukahlukene efana namanzi, umusi, uwoyela, i-nitric acid, i-acetic acid, i-oxidizing media, urea, njll.
