1. Ts'ebeliso ea valve ea Wafer Check:
Sesepa sa ho hlahloba se kenngoa tsamaisong ea liphaephe, 'me mosebetsi oa eona o ka sehloohong ke ho thibela ho khutlela morao ha sehare.Sesepa sa ho hlahloba ke valve ea othomathiki e buloang le ho koaloa ho latela khatello ea seaplane.Sekhahla sa ho hlahloba valvee loketse khatello ea lebitso PN1.0MPa ~ 42.0MPa, Class150 ~ 25000;bophara ka lebitso DN15 ~ 1200mm, NPS1/2 ~ 48;mocheso o sebetsang -196 ~ 540 ℃ liphaepheng tse fapaneng, tse sebelisetsoang ho thibela Medium backflow.Ka ho khetha lisebelisoa tse fapaneng, e ka sebelisoa mecheng ea litaba e fapaneng joalo ka metsi, mouoane, oli, asiti ea nitric, asiti ea acetic, mahareng a oxidizing e matla le uric acid.
Taba ea bobeli, lisebelisoa tsa mantlha tsa valve ea ho hlahloba liphaephe:
Ho na le tšepe e entsoeng ka tšepe, tšepe ea carbon, tšepe ea mocheso o tlase, tšepe ea mekhahlelo e 'meli (F51/F55), motsoako oa titanium, boronse ba aluminium, INCONEL, tšepe e sa hloekang SS304, SS304L, SS316, SS316L, chrome molybdenum steel, Monel (400/500), 20 # motsoako, Hastelloy le lisebelisoa tse ling tsa tšepe.
3. Likarolo tsa sebopeho sa valve ea ho hlahloba liphaephe:
1. Bolelele ba sebopeho bo khuts'oane, 'me bolelele ba eona ba sebopeho ke 1/4 ~ 1/8 feela ea valve ea setso ea ho hlahloba flange.
2. Boholo bo nyane le boima bo bobebe, boima ba eona ke 1/4 ~ 1/20 feela ea valve ea setso ea ho hlahloba flange.
3. Sesepa sa valve se koala ka potlako 'me khatello ea hamore ea metsi e nyenyane
4. Liphaephe tse peli tse rapameng kapa liphaephe tse otlolohileng li ka sebelisoa, ho bonolo ho li kenya
5. Mocha oa phallo o boreleli mme ho hanyetsa mokelikeli ho nyane
6. Ketso e utloahalang le ts'ebetso e ntle ea ho tiisa
7. Leeto la li-valve disc le khutšoanyane 'me matla a ts'ebetso ea ho koala a nyenyane
8. Sebopeho sa kakaretso se bonolo ebile se kopane, 'me sebopeho se setle
9. Bophelo bo bolelele ba tšebeletso le ts'ebetso e tšepahalang
Ntlha ea bone, liphoso tse tloaelehileng tsa valve ea ho hlahloba ke:
1. Sesepa sa valve se robehile
Khatello ea seaplane pele le ka mor'a valve ea ho hlahloba e boemong bo leka-lekaneng le "saw" e kopanetsoeng.Hangata diski ea valve e otloa ka setulo sa valve, 'me diski ea valve e entsoeng ka lisebelisoa tse ling tse brittle (tse kang tšepe ea tšepe, koporo, joalo-joalo) e robehile.Mokhoa oa thibelo ke ho sebelisa valve ea ho hlahloba e nang le disc e le thepa ea ductile.
2. Merero e bohareng
Sebaka sa ho tiisa se senyehile;litšila li qabeletsoe.Ka ho lokisa sebaka sa ho tiisa le ho hloekisa litšila, ho khutlela morao ho ka thibeloa.
