Li-valve tsa cheke ke life?

E le sesebelisoa sa bohlokoa ho thibela ho khutlela morao,hlahloba li-valveli sebelisoa haholo tsamaisong ea liphaephe. Ho ea ka meaho e fapaneng le melaoana ea ts'ebetso, li-valve tsa cheke li arotsoe haholo ka mekhahlelo e latelang:

1. Swing ho hlahloba valve

Rotary check valve e bula le ho koala ka ho potoloha disc ea valve ho potoloha axis e tsitsitseng. Ha seaplane se phalla pele, valve disc e sutumetsoa e bulehile; Ha u khutlela morao, "valve disc" e koala tlas'a boima ba eona le matla a karabelo ea seaplane. Melemo ea eona ke ho hanyetsa phallo e fokolang, ho bula ka potlako le ho koala, ho loketse bakeng sa bophara bo boholo, maemo a tlaase a phallo e kang lipompo kapa liphaephe tse otlolohileng. Leha ho le joalo, phello ea hamore ea metsi e ka etsahala nakong ea phallo e phahameng ka potlako, 'me sesebelisoa sa buffer sea hlokahala.

2. Phahamisa valve ea ho hlahloba

Sesepa sa valve sa liftho hlahloba valvee tsamaellana le axis e emeng ya mmele wa valve. Ha e phalla pele, khatello e bohareng e sutumelletsa "valve disc" holimo; Ha u khutlela morao, "valve disc" e oela tlas'a ketso ea matla a khoheli kapa matla a selemo, e khaola bohareng. Mofuta ona oa li-valve tsa ho hlahloba o na le ts'ebetso e ntle ea ho tiisa, empa ho hanyetsa phallo e phahameng, 'me e sebelisoa haholo ka lisebelisoa tse nyenyane, tse nang le khatello e phahameng kapa tse kentsoeng ka holimo, tse kang litsamaiso tsa mouoane.

3. Butterfly hlahloba valve

Butterfly check valve e kopanya litšobotsi tsa li-valve tsa rotary le serurubele, tse nang le disk e chitja e potolohang ho pota-pota bohareng. E na le sebopeho se kopaneng le boima bo bobebe, bo loketseng liphaephe tse bophara bo boholo le khatello e tlase, 'me hangata e sebelisoa ho phepelo ea metsi le boenjiniere ba drainage. Empa ho tiisa ho batla ho fokola 'me ho hloka tlhokomelo ea kamehla.

4. Lebelo la ho hlahloba diaphragm

Li-valve tsa tlhahlobo ea diaphragm li sebelisa deformation ea elastic ea li-diaphragm tsa rabara ho laola ho bula le ho koala. Ha mochine o phallang o ea pele, diaphragm e otlolloa; Ha o khutlela morao, diaphragm e khutlela morao ho tiisa mocha. Mofuta ona oa li-valve tsa ho hlahloba ha o na likhohlano tsa mechine le bophelo ba nako e telele ea tšebeletso, empa mocheso oa eona le khatello ea khatello e fokotsehile, 'me e sebelisoa haholo bakeng sa ho hloekisa mecha ea litaba kapa mekhoa e tlaase ea khatello.

5. Piston hlahloba valve

Sesepa sa ho hlahloba piston se bula le ho koala ka tšebelisano ea piston le selemo. Khatello e mahareng e hlola matla a selemo ho sutumelletsa piston hore e tsamaee, 'me selemo se khutla ebe se koala ha se kheloha. E na le ts'ebetso e babatsehang ea ho tiisa 'me e loketse mocheso o phahameng le maemo a khatello e phahameng, joalo ka indasteri ea petrochemical, empa sebopeho sa eona se rarahane ebile litšenyehelo li phahame.

Maemo a sebetsang a mefuta e fapaneng eahlahloba li-valvee hloka ho khethoa ka botlalo ho latela litšoaneleho tsa seaplane, khatello, sekhahla sa phallo, le maemo a ho kenya ho netefatsa ts'ebetso e bolokehileng le e sebetsang ea sistimi.
