Kenyelletso ea ts'ebeliso, lisebelisoa tse ka sehloohong le litšobotsi tsa sebopeho sa valve ea ho hlahloba liphaephe

Hlahloba valve e bua ka valve e bulang le ho koala sekhahla sa valve ka ho itšetleha ka phallo ea sehare ka boeona ho thibela ho khutla ha sehare, se tsejoang hape e le.ho hlahloba valve, valve ea tsela e le 'ngoe, valve e phallang ka morao le khatello ea morao. Theho hlahloba valveke valve ea othomathike eo mosebetsi oa eona o ka sehloohong e leng ho thibela ho khutla ha sehare, ho potoloha ka morao ha pompo le mochini o khannang, le ho ntšoa ha sehare ka har'a setshelo. Li-valve tsa ho hlahloba li ka boela tsa sebelisoa meleng e fanang ka lisebelisoa tse thusang moo khatello e ka 'nang ea phahama ka holim'a khatello ea tsamaiso.

1.To sebelisa valve ea ho hlahloba liphaephe:

Theho hlahloba valve e kenngoa tsamaisong ea liphaephe, 'me mosebetsi oa eona o ka sehloohong ke ho thibela ho khutlela morao ha seaplane. Theho hlahloba valveke valve ea othomathiki e buloang le ho koaloa ho latela khatello e mahareng.Sekhahla sa ho hlahloba valve e loketse khatello ea lebitso PN1.0MPa ~ 42.0MPa, Class150 ~ 25000; bophara ka lebitso DN15 ~ 1200mm, NPS1/2 ~ 48; Phallo e mahareng. 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, sehare se matla sa oxidizing le uric acid.

2.To lintho tse ka sehloohong tsathipa e hlahlobang valve:

Ho na le tšepe carbon, tlaase mocheso tšepe, dual phase steel (F51/F55), titanium alloy, aluminium bronze, INCONEL, SS304, SS304L, SS316, SS316L, chrome molybdenum steel, Monel (400/500), 20# alloy, Hastelloy le lisebelisoa tse ling tsa tšepe.

3. Likarolo tsa sebopeho sathipa e hlahlobang valve:

A. 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.

B. Boholo bo nyane le boima bo bobebe, boima ba eona ke 1/4 ~ 1/20 feela ea valve ea setso ea ho hlahloba flange

C. The valve disc e koala ka potlako 'me khatello ea hamore ea metsi e nyenyane

D. Ka bobeli liphaephe tse rapameng kapa liphaephe tse otlolohileng li ka sebelisoa, ho bonolo ho li kenya

E. Mocha oa phallo o boreleli mme ho hanyetsa mokelikeli ho nyane

F. Ketso e hlokolosi le ts'ebetso e ntle ea ho tiisa

G. Leeto la li-valve disc le khuts'oane mme matla a ts'ebetso a koalang a nyane

H. Sebopeho sa kakaretso se bonolo ebile se kopane, 'me sebopeho se setle

I. Bophelo bo bolelele ba tšebeletso le ts'ebetso e tšepahalang

4.Tliphoso tse tloaelehileng tsa valve ea ho hlahloba ke:

A. Sesepa sa valve se robehile

Khatello ea seaplane pele le ka mor'a valve ea ho hlahloba e boemong bo haufi le ho leka-lekana 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.

B. Phallo e mahareng

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.
